Masterbatch is composed of carrier resin, filler and various additives. The limit of additives or filler content in masterbatch is several times to more than ten times higher than that in actual plastic products. In the process of molding, the ratio of masterbatch and matrix resin must be adjusted according to the content of relevant components in masterbatch and the amount to be added in actual products. Masterbatch is the most representative masterbatch in plastic masterbatch. Polyethylene wax is widely used in masterbatch processing. The purpose of adding pe wax is not only to improve the processing performance of  masterbatch system, but also to promote the dispersion of pigments in masterbatch. Pigment dispersion is very important for masterbatch. The quality of  masterbatch mainly depends on the dispersion of pigment.Qingdao Sainuo pe wax SN9079W has stable index, high melting point, high hardness than oligomers, low weight loss, it can improve the processing performance of products; With good dispersion ability can replace the medium and high low polymer dispersion force, and solve the dispersion and lubrication capacity. Widely used in filler masterbatch, color masterbatch, transparent barium sulfate masterbatch, etc.The masterbatch with good pigment dispersion has high coloring power, good coloring quality and low coloring cost. The main additives used in masterbatch are dispersant and surface treatment agent. The function of dispersant is to improve the processing fluidity of masterbatch, which is conducive to more uniform dispersion of masterbatch in matrix resin. Common dispersants include white oil (Liquid Paraffin), paraffin, dioctyl phthalate (BOP), low molecular weight polyethylene (polyethylene wax) and stearic acid. The main properties of dispersant can be selected and used according to the performance characteristics of filler and carrier resin. Polyethylene wax can improve the dispersion level of pigment to a certain extent. It is the most commonly used dispersant in the production of masterbatch.When the masterbatch system containing polyethylene wax is processed, the pe wax melts before the carrier resin and is coated on the pigment surface. Due to its low viscosity and good compatibility with pigments, polyethylene wax is easy to wet pigments, penetrate into the internal pores of pigment aggregates, weaken cohesion, make pigment aggregates easier to open under external shear, and new particles can also be quickly wetted and protected. In addition, polyethylene wax can reduce the viscosity and improve the fluidity of the system. It can effectively solve the precipitation phenomenon of filling masterbatch products; It can effectively reduce the smoke generated in the production environment and reduce material consumption.

The color masterbatch is a plastic colorant composed of a high proportion of pigments or additives and thermoplastic resin. The selected resin has good wetting and dispersion effect on the colorant and good compatibility with the colored material. Today, Qingdao Sainuo pe wax manufacturer takes you to know about color masterbatch.1. Precautions for operation of color masterbatch in injection molding machine(1) The emergence of color masterbatch and large-scale use make products of various colors appear in our life. We only need to mix and stir with resin particles according to the specified ratio. The mixing of injection molding machine generally has multiple temperature areas. In order to make the color masterbatch melt quickly after entering the mixing chamber, the temperature near the blanking port should be slightly higher, so as to facilitate the mixing of plastic resin and color masterbatch as soon as possible, which is conducive to better dispersion of pigment in products.(2) In the process of using color masterbatch, in addition to the quality of the product itself, our operation is also very important. If there are problems in the operation process, our finished products may be unqualified. Therefore, keep the above operation points in mind during operation to avoid problems.2. Advantages of Color Masterbatch compared with toner(1) It improves the environmental pollution caused by the flying toner. At present, the environmental protection problem is becoming more and more serious. The environmental protection work is more strict than before. The color masterbatch is a very good choice. It is easy to change color in the process of use, and there is no need to carry out special cleaning on the extruder hopper, which is more convenient.(2) Strong pertinence and correct color matching. Because the color masterbatch weaving factory has reasonably selected pigments (dyes), additives, processing equipment and processing technology according to the performance of applicable resins in the manufacturing process, timely corrected and supplemented the color differences that may be caused by different batches of toners in the production process, and then inspected when leaving the factory, it can ensure the color masterbatch of the same brand, The color of the first and second batches remained relatively stable.(3) Compared with making plastic parts after batch resin dry dyeing and granulation, the use of color masterbatch can reduce the changes of resin properties caused by secondary processing of plastic products, which is conducive to the improvement of the service life of plastic products.(4) In the processing process, under the action of additives, the color masterbatch is fully combined with the carrier resin after full mixing. When in use, it is placed in the resin to be processed according to a certain proportion, and the color masterbatch quickly enters the role and blends with the resin. The compatibility is obviously better than that of toner coloring.3. Precautions when using color masterbatch in spinning(1) Color masterbatch is a product mixed with resin and pigment. Compared with ordinary pigments, it is healthier and has long adhesion, so it is often used in garment spinning. However, if the pigment is used improperly, it will lead to obvious color difference on the spinning cloth, which will not only affect the beauty, but also lead to poor quality. When you want to mix with the primary color slice, you should pay special attention to the problem of static electricity to avoid separating the color masterbatch, uneven color mixing and attaching it to the bucket wall of the material. Pay attention to the moisture content of the pigment. If the moisture content is high, the color content of the same pigment may fluctuate. Generally, the water content less than 0.3% will not affect the spinnability; The coloring attempt or dilution ratio shall be determined according to the luster of the fiber. The dilution ratio of pigments with different concentrations is also different. For high concentration pigments, due to the large dilution ratio, pay attention to the uniformity of fiber luster. It should be noted that the pigment may react with other additives in the spinning solution. First, the additive can not play the role of maintaining the physical and mechanical properties of the fiber, and second, it reduces the coloring effect of the pigment. When spinning, pay attention to the diffusion of color masterbatch. Sainuo's polyethylene wax 118W can solve this problem well.4. Requirements for adding color masterbatch to polypropylene filament(1) Heat resistanceDue to the different spinning processes of polypropylene fiber, the spinning temperature is 230-300 ℃, so the selected pigment must have excellent heat resistance. The classic pigment red 42:2 is widely used in polypropylene carpet silk. Attention should be paid to the phenomenon that it will lose crystal water at high spinning temperature and absorb water and change color repeatedly during storage.(2) DispersibilityWhen the color masterbatch is used for the dispersion of polypropylene fiber, it needs to consider: wire breakage in spinneret hole, tensile deformation and tensile wire breakage. Replacement frequency and service life of filter components. In particular, ultra-fine denier polypropylene fiber is a new variety developing towards the thinness of simulated silk and fabric, which puts forward higher requirements for pigment dispersion. Polypropylene Color Masterbatch uses the filter pressure rise to measure the dispersion quality of Color Masterbatch, which is called DF value. Generally, the DF value of polypropylene color masterbatch is required to be less than 1.0. Sainuo polyethylene wax and dispersant can well help color masterbatch customers.(3) Weather resistancePolypropylene fiber is the lightest fiber among common chemical fibers. It has almost no moisture absorption and high strength. The fabric is stable in size, wear resistance, good elasticity and good chemical stability. Therefore, it is widely used in sunshade cloth. Therefore, it is necessary to have good weather resistance. When selecting pigment varieties with good weather resistance, pay attention to selecting pigments with large particle size and adding appropriate antioxidants, Anti aging additives such as anti ultraviolet agent.(4) Melt indexThe melt index of color masterbatch for polypropylene filament is required to be 15-50g / 10min, the melt index of color masterbatch for spun bonded non-woven fabric is required to be 40-60g / 10min, and the melt index of color masterbatch for melt blown non-woven fabric is 800-1500g / 10mi n. 4.5-5.0g/1min. Therefore, when selecting color masterbatch, we should pay attention to whether its melt index can meet the melt index required by polypropylene filament.(5) Moisture contentIf the spinning speed of polypropylene filament is 600-800m / min, the moisture requirements for polypropylene resin and color masterbatch are not high. Such as one-step spinning, the spinning speed is as high as 2000-3000m / min, or even faster. The slightly high water content of Color Masterbatch often causes spinning abnormalities. Generally speaking, the water content of color masterbatch is required to be controlled at about 500mg / kg.(6) Food gradeWith the continuous enhancement of people's awareness of environmental protection, polypropylene color masterbatch is required not to contain a variety of heavy metal factors that restrict the use, and various pigments containing lead and cadmium must not be used, which meets the requirements of ecological textiles. Sano lubricant and dispersant meet the FDA test report.5. Details to pay attention to when selecting color masterbatch(1) The pigment selected for heat-resistant color masterbatch is basically required to withstand the temperature in the production process of polypropylene fiber and maintain its performance stability. The temperature resistance temperature is generally above 270 ~ 280 ℃. Sano 220 is a very useful dispersant with excellent temperature resistance.(2) The pigment for dispersive masterbatch shall have excellent dispersibility and be evenly dispersed in the masterbatch, and the dispersant used will not reduce the quality of polypropylene fiber. Otherwise, it can not produce high-quality stock solution colored fibers, the operation is unstable, and it is easy to break or produce abnormal fibers when drawing fibers. (3) Brightness polypropylene stock solution coloring has a variety of uses, including for bedspread base cloth and knitted fabrics, requiring bright colors. Because organic pigments are bright and easy to color, organic pigments should be used for the above purposes.(4) Light fastness under the action of light, some pigments have photosensitive effect, which makes the colored fibers fade and brittle. The light fastness of pigments is basically related to their chemical structure. Therefore, when making color masterbatch, we should pay full attention to the light fastness of pigments. When light resistant pigments need to be used, we can consider adding ultraviolet absorbers.(5) The pigment used in the stability masterbatch should have excellent stability to the color polypropylene fiber. That is, when the colored fiber polymer is exposed to heat, light or high temperature for a long time, the pigment will not react with the fiber to form new chemical groups, so that the performance of the polymer is low.6. Role of color masterbatch in plastic productsOrdinary carbon black is made of polyethylene resin through high temperature and close training. Ordinary carbon black has strong adaptability and easy evacuation. It is applicable to general resin, film blowing, wire rod, pipe, plastic, plastic, wire drawing, etc. The function of color masterbatch is dyeing. 7. How to distinguish the quality of Color Masterbatch(1) There are usually two kinds of particles, one is cylindrical and the other is oval. No matter which kind, the particles must be uniform, the particle size must be the same, and the surface must be smooth and free of burrs. The particles come from the basic processing technology, strip drawing and grain cutting. If the size is different and the surface is rough, it means that the processing technology of the color masterbatch itself is very problematic, so do not expect the dispersion of the color masterbatch product to have a good performance.(2) With the market situation, the profit space of color masterbatch has been compressed again and again. At this time, we will find ways to reduce the cost. Adding mineral powder to the color masterbatch is a way. The influence of adding mineral powder on the addition of color masterbatch to plastic products, if a small amount is favorable, it can increase the rigidity, strength, heat resistance and size shrinkage of plastic products. The test ash content is generally less than 5%, which has a low impact on product quality, except for special requirements; If the content of calcium powder is too high, it is not appropriate.(3) The higher the pigment concentration, the less the addition proportion and save the addition amount. However, the higher the pigment concentration, the higher the process requirements. For example, adding 45% of the pigment concentration to ordinary machines basically reaches the upper limit, but for better extruders (imported), the pigment can be added up to more than 50%, and the pigment dispersion can be done very well. Sainuo 619 can solve this problem well!(4) With the same color and the same concentration, the coloring ability of different toners is different. Selecting color masterbatch with strong coloring power can reduce the amount of addition and reduce the cost. After years of research and accumulation, Sainuo has developed this 619, which has a good dispersing and brightening effect. It can also improve the flexibility of masterbatch and products.(5) The better the dispersion of Color Masterbatch, the more uniform the color of the product. For ordinary injection molding products, the difference is not very big, but for very thin film blowing products, the difference is very obvious. The film products made of color masterbatch with good dispersion have no obvious defects on the surface; However, this difference is reflected in the surface colored spots, color lines and holes of film products prepared by ordinary color masterbatch. After years of research and accumulation, Sainuo has developed this 619 to solve the difficult dispersion and high concentration color masterbatch system.Qingdao Sainuo Chemical Co., Ltd.

The chemical composition of PVC foam board is polyvinyl chloride, so it is also called foam polyvinyl chloride board.Five factors affecting the quality of PVC foam boardIn the extrusion process of PVC foam board, the problems encountered can be basically classified into five categories. The first is the problem of stability; The second is melt strength; The third is lubrication; The fourth is the problem of decentralization. These four types of problems, especially the first three types of problems, will restrict and cross influence each other. From the surface phenomenon, it is sometimes difficult to distinguish them immediately. It is necessary to conduct in-depth observation and analysis to find the root cause of the problem.pe wax for PVC foam board(1) Insufficient stability will affect the whole board surface, which turns yellow and the foamed sheet is brittle(2) Insufficient melt strength will lead to large foam cells and long longitudinal bubbles.The most direct way to judge whether the melt strength is insufficient is to press the plate wrapped on the middle roll with your fingers behind the three rolls. When the melt strength is good, you can feel elasticity when pressing. If it is difficult to bounce after pressing, it indicates that the melt strength is poor. Because the screw structure and cooling mode are quite different, it is difficult to judge whether the temperature is reasonable. Generally speaking, the temperature in zone 3-5 is better to be low within the allowable load of the extruder. In order to obtain uniform foaming products in foamed pipes, it is also necessary to ensure that PVC materials have good melt strength. Therefore, the quality and model of foaming regulator are very important. Of course, yellow and white hair foaming agent should also be well matched.(3) LubricantThe lubricant is divided into external lubricant and internal lubricant. External sliding is conducive to demoulding and is beneficial to the smoothness of the plate surface. Too little external sliding makes it difficult to control the temperature in zone 5 of the extruder and easy to rise, which will lead to high confluence core temperature, large bubbles, string bubbles, yellowing and other problems in the middle of the plate, and the plate surface is not smooth; If there is much external sliding, the precipitation will be serious, which is reflected in the structure in the die and the precipitation of external sliding on the plate surface, and some individual phenomena will move back and forth irregularly on the plate surface. Internal sliding is conducive to plasticization and melt fluidity. Insufficient internal sliding makes it difficult to control the thickness of the plate surface, which is manifested in the thickness of the plate in the middle and thin on both sides; The phenomenon of high confluence core temperature is easy to occur due to more internal sliding.(4) Poor dispersion will lead to the phenomenon that the plate surface is not smoothProcess temperature control: the three problems mentioned above are fundamental, basic and deep-seated. Compared with the above three problems, the process temperature control is much more intuitive. It is a surface problem, but poor temperature control will induce the emergence of fundamental problems. Increasing the processing temperature will reduce the material stability time and cause stability problems; The original lubrication balance will be broken, which is generally manifested in insufficient external lubrication. Especially in the later stage, the amount of external lubrication needs to be increased; The increase of temperature will also lead to the decrease of melt strength, the increase of foam cell, the decrease of cell number, the brittleness and fracture of foam sheet; The increase of temperature reduces the melt strength and also reduces the melt viscosity. The viscosity decreases and the shear dispersion ability decreases. For screws with weak dispersion ability, uneven dispersion sometimes occurs.(5) The more foaming agent, the better foaming, the smaller density and the lighter?In the actual production, we met many customers of PVC foam products. The products had large bubbles or the weight could not be reduced. We asked all kinds of expert friends and got the answer that made them believe: This is that the foaming agent was added less and did not grow up, so we had to add more foaming agent, which naturally grew up. As a result, the situation was worse, so they discussed another way to increase the amount of foaming regulator, and the results improved until the amount of regulator increased enough to avoid any problems.Qingdao Sainuo Chemical Co., Ltd.
