Plastic profiles due to the huge market demand and broad prospects for development in recent years has been the rapid development of our country, because of the intensity of competition in the market, all plastic machinery manufacturers are considered a problem, how to improve the plastic profiles under the premise of ensuring product quality productivity and product qualification rate, the maximum capacity of play equipment to reduce production costs. [1] The growing competition in the industry of plastic profiles, plastic profiles large mergers and acquisitions integration and capital operation is becoming more frequent, more and more attention to the domestic producers of plastic profiles of outstanding research on the industry market, especially for enterprise development environment and customer needs depth study of the trend change. Because of this special-shaped plastic pvc pipe, a large number of outstanding domestic brands of plastic profiles rapid rise, has become the industry leader in plastic profiles! PVC plastic profiles formula mainly composed of PVC resins and additives which aid is divided by function : heat stabilizers, lubricating plastic pvc shaped pipe supply, agents, processing modifiers, impact modifiers, fillers, anti-aging agents, coloring agents and the like. Before designing PVC formulations, should first understand the PVC resins and various additives performance. [3] 1, the resin should choose PVC-SC5 resin or PVC-SG4 resin, that is, the degree of polymerization of PVC resin in 1200-1000. 2, shall be added to the thermal stability of the system. According to the actual requirements of production options, attention synergy and antagonism between the effects of heat stabilizers. 3, shall be added to the impact modifier. You can choose the CPE and ACR impact modifiers. According to other components of the formulation and extruder plasticizing capacity, adding the amount of 8-12 copies. CPE lower prices pvc plastic shaped pipe products, wide range of sources; ACR anti-aging ability, high weld strength. 4, the amount added to the lubrication system. Lubrication systems can reduce the load of processing machinery, the product is smooth, but too much can cause fillet strength. 5, by adding processing modifier can improve the quality of plastics, improve product appearance. General joined ACR processing modifier, amount 1-2 parts. 6, adding fillers can reduce costs and increase the rigidity of the profile, but a greater impact on the low-temperature impact strength, you should choose a higher fineness of the activity of PCC added, addition of 5-15 copies. 7, must be added in order to play a certain amount of titanium dioxide UV shielding effect. Rutile titanium dioxide should be selected, adding the amount of 4-6 parts. UV absorbers can be added if necessary UV-531, UV327, etc. in order to increase the profile of anti-aging ability. 8, the amount added to the blue and fluorescent brighteners, can significantly improve the color profiles. 9, in the design of the formula should be simplified as much as possible without adding liquid additives, and in batches according to the order of addition of the formula I, into material, Ⅱ number expected, Ⅲ number of packaging materials were based on the mixing process requirements (see mixing problems).
