Resin absorbency is not very high, for example, when the allowable value is below 0.1 ~ 0_2%, it can be processed without drying treatment for packing tightly, properly stored and product requirements are not too high. However, if the moisture content in the granules exceeds the prescribed value, it must be dried before treatment. It is also necessary to dry for the special grade particles?or?products, such as electroplated products. Molding process specification 1. injection temperature: including the barrel temperature (also can be divided into the rear, the middle, the first three sections), the nozzle temperature and mold temperature. The effect of temperature on the viscosity of ABS melt is not as obvious as the injection pressure, but it is beneficial to the mold of thin wall products under the condition of high temperature. The decomposition temperature of ABS, the theory on 00amv 270t: above, but in the actual process of injection molding, due to time and other process conditions, resin often 2501?or?so began to change, while ABS contained in the rubber phase does not adapt to high temperature, otherwise it will affect the product performance. ABS molding temperature, heat resistant resin in electroplating grade etc. grade requirements temperature slightly higher (210 - 2501) to change the chopsticks melt filling difficult?or?conducive to the performance of electroplating 4, electrical properties ABS has good electrical insulation and is almost unaffected by temperature, humidity and frequency. It can be used in most of the environment. 5, environmental performance ABS is not affected by water, inorganic salts, alkyl alcohols and hydrocarbon solvents and various acids, but it can be dissolved in ketones, aldehydes and chlorinated hydrocarbons. It will cause stress cracking by erosion of glacial acetic acid and vegetable oil. Performance testing is to test various performance indicators of the system by using automated testing tools to simulate various normal, peak and abnormal load conditions. Preparation materials: 1, 3- butadiene; styrene; acrylonitrile Production methods: ABS production methods are divided into mixing method and grafting method. Nowadays, the main producers in the world mostly use the method of first grafting and mixing. The method is also divided into emulsion grafting, emulsion SAN mixing, emulsion grafting, suspension SAN mixing, emulsion grafting and bulk SAN mixing. The emerging bulk grafting method has a great advantage in both production cost and environmental impact, which is the focus of future research. PP The blending modification of PP with compatibilizer and reactive blending technology is the main characteristic of the current PP blending. It can greatly improve the impact resistance of PP on the premise of ensuring the tensile strength and bending strength of the blends. Compatibilizer can improve the interfacial bonding state in the blend system, which is conducive to the realization of the stability of the microphase multiphase system, while the macroscopic structure is homogeneous. Reactive compatibilizer not only has the effect of general compatibilizer, but also produces molecular links between two phases in the blending process, which significantly improves the properties of the blend. Although the two element blend system of PP/ elastomer has good toughness, it often reduces the strength and stiffness of the material, and reduces the heat resistance. With the addition of Compatibilization?or?synergistic effect in the two - element blending system, a multicomponent blending system is formed, and its comprehensive properties can be further improved. In order to improve the hardness, thermal deformation temperature and dimensional stability of toughened PP, the filler?or?reinforced material treated with coupling agent activation can be strengthened. For example, the elastomer / inorganic rigid particle /PP three element composite toughening system is used to achieve toughening and strengthening of PP, improve the comprehensive properties of materials, and have low cost. In 2003, China's car output was about 4400000, the fourth in the world, up 36.6% from the same year. According to the ESM WerWide in the United States, "China's car production will exceed 6 million cars in 2008, 2015 will exceed Japan and the second place in the world." This prediction has been broken. In 2010, China's auto sales and sales volume were over 18 million vehicles, which surpassed 17 million cars in the United States. The development of automobile industry can not be separated from the process of auto plastic. At present, the self-sufficiency rate of China's engineering plastics is less than 16%. According to the prediction of China Engineering Plastics Association, the demand growth rate of engineering plastics in China is 15% in 2005, and about 10% in 2010, and the demand will increase from 440 thousand T in 2000 to 1 million 400 thousand T in 2010. The demand for engineering plastics in China's auto manufacturing industry is increasing rapidly. By 2010, the total amount will reach 940 thousand T (the amount of plastic used for the car's weight of 5%~10%).
