Huicong plastic network news: process AIDS, the full name is: processing AIDS. Or processing AIDS. It is an emerging technology that has developed rapidly in the world in recent years. In fact, the development and use of process AIDS, almost in sync with the development of plastic raw materials, have been decades of history. For example, the traditional affordable lubricants stearate (zinc salt, calcium salt, magnesium salt, cadmium salt), as early as the 40's and 50's, has been widely used in plastic processing. Even at present, stearate is still widely used in plastic processing. Therefore, as practitioners of the plastic processing industry, we must first establish a concept, that is, the application of process AIDS has long existed in the traditional plastic processing industry. However, according to the contact with a large number of plastic industry practitioners found that although many people engaged in plastic processing for decades, they do not know that almost every kind of plastic raw materials contain processing AIDS! Therefore, when introducing advanced process AIDS to these senior plastics industry practitioners, most people will ask: "Why use process AIDS?" Or even doubt the need for process AIDS. The use of process AIDS is completely necessary. The simplest analogy is as follows: People must understand that in order for a car to run, gasoline (or some other fuel) must be added. But do not forget that the car must also add various types of lubricating oil, such as: engine oil, gearbox oil, bearing oil and so on. Otherwise, the car will not drive fast, the parts will wear quickly, and there will be a lot of vibration and noise. As with this simple analogy, all kinds of process additives are the "lubricating oil" of plastic melt. (A) The basic classification of plastic industry additives? Plastic industry additives are roughly divided into: (1) functional additives. The characteristic of functional additives is that they have some special function, so that the performance of plastics has been improved in some aspects. For example: antioxidant, UV absorbent, etc. (2) Process additives. The characteristics of process AIDS are that they do not directly improve the performance of plastics, but improve plastic. Be processed to obtain a good quality final product. For example: internal lubricants, external lubricants, etc. (2) What is internal lubricant? The internal lubricant is the lubricant between the carbon chains of plastic molecules. It is used to increase the fluidity of plastic melt to improve the processing performance. For example, LLDPE with Mi(melt flow index)0.8-1.0 has significantly higher tension, puncture resistance and tear resistance than LLDPE with Mi2. However, the LLDPE of Mi1 is difficult to plasticize its melt because of its large melt viscosity and small screw torque. If an internal lubricant is added, the fluidity of the melt is improved and it becomes easy to process. (3) What is external lubricant? External lubricant is a lubricant that reduces the viscosity resistance of plastic melt and steel surface of processing equipment. The plastic melt has good processing characteristics. For example, the LLDPE of Mi1 has great viscous resistance between its melt and the steel surface of the processing equipment. Without external lubricant, it can not be made into a smooth surface film. With the help of external lubricants, high surface smoothness film with high tension, high puncture resistance and high tear resistance can be made. (4) What are the effects of process AIDS? The efficiency of process additives is generally summarized as follows: (1) Reduce the power consumption in the plastic processing process. For example, the PEA series of high-tech process additives can generally increase production by 10-15% under the original power consumption level. That is, save 10-15% of electricity consumption and reduce 10-15% of business administration costs at the same time. (2) Improve the mechanical strength, surface smoothness and surface brightness of plastic products. For example, the PEA series of high-tech process additives can improve the plasticizing efficiency of plastic melt, so the longitudinal and horizontal tension of the film material is correspondingly improved. In addition, it can also improve the microscopic smoothness of the film surface to improve the surface brightness and printing quality. (3) Eliminate tiny crystal points on the surface of the film that are visible to the human eye or can only be observed by a microscope. Eliminate fine printing "white spots". (5) Will the use of process AIDS increase production costs? On the face of it, the use of any additive will have a corresponding additional use cost. However, for process auxiliaries, a large number of facts have proved that the additional cost of using process auxiliaries can not only be offset by the comprehensive benefits of several aspects, such as the reduction in power consumption, or the decrease in enterprise management costs caused by the increase in output, the decline in the rate of waste and defective products, and the use of affordable raw materials. A large number of facts have proved that the use of process additives not only does not increase the cost, but also reduces the total cost of production. (6) The use of process auxiliaries is an important technical measure to increase the profitability of enterprises. A large number of facts have proved that the use of process auxiliaries can improve the quality of products, improve the competitiveness of products, and thus improve the profitability of enterprises. For example: the use of high-tech process aid PEA, because it can make Mi1's high tensile LLDPE smooth processing, therefore, under the same tensile conditions, the plastic bag can be reduced. For plastic bag manufacturers, the price can be increased by ton; For buyers, the number of plastic bags per ton can be increased, and both sides can benefit. Another example: the use of high-tech process additives PEA can significantly improve the fine printing quality of plastic bags, so that plastic bags are more suitable for high-grade product packaging, and the price of plastic bags has been correspondingly improved.
