PPS1, electrical insulation (especially high frequency insulation) is excellent, white hard and brittle, falling on the floor with metal noise, light transmission rate is next to plexiglass, coloring and water resistance, chemical stability is good. Have excellent flame retardancy? For non flammable plastics. 2, the strength is general, the rigidity is very good, but the quality is crisp, is easy to produce the stress embrittlement, does not endure benzene, the gasoline and so on organic solvent. The long-term use temperature can reach 260 degrees, maintains the stability in the 400 degree air?or?the nitrogen. By adding glass fiber?or?other reinforcing material modified? Can make the impact strength greatly improved? Heat resistance and other mechanical properties are also improved? The density increased to 1.6-1.9? Mold shrinkage to 0.15-0.25% suitable for the production of heat-resistant parts. Insulation and chemical instrument. Optical instrument parts etc.. The molding performance is 1. amorphous material, the moisture absorption is small, but it should be dry after forming. 2. fluidity is between ABS and PC? Fast solidification, small contraction, easy decomposition, high injection pressure and injection speed. The mold temperature is 100-150 degrees. The main channel taper should be large and the channel should be short. The scope of application can be used to make materials such as PPS tube, PPS plate and so on. It is used in building and home. PPS, called polyphenylenesulphide, English name Polyphenylenesulfide, referred to as PPS (hereinafter referred to as PPS?or?PPS). The molecular structure of PPS is relatively simple. The main chain of molecules is alternately arranged by benzene and sulfur atoms. A large number of benzene rings give PPS rigidity and a large number of thioether bonds, which provide flexibility. The molecular structure is symmetrical, easy to crystallize, no polarity, good electrical properties, no water absorption.

Table 1 formula and process for whole surface treatment project process parameters Acetone / portion 1 water / 3 temperature / centigrade temperature treatment time /mi15 - 20 (2) oil removal ABS plastic surface often Zhanyou oil, hand sweat and release agent, it will make the paint poor adhesion, coating cracking, blistering and shedding. Oil removal should be carried out before coating. ABS plastic parts are usually cleaned with gasoline?or?alcohol and then chemically deoiling. The process formula is listed in Table 2. Table 2 oil removal process formula and process The project process parameters of sodium hydroxide (S/L) 50~70 (S/L) 20~30 sodium phosphate, sodium carbonate (S/L) 10~20 surfactant (S/L) 5~10 / 50~60 C temperature treatment time /min10 to thoroughly clean the residual lye surface 15 chemical oil, and finally clean with water, dry?or?drying. (3) power removal and dust removal Plastic products are insulators, the surface resistance is usually about 1013 Omega, and it is easy to produce static electricity. After being charged, it is easy to adsorb fine dust in the air and attach to the surface. The electrostatic adsorption dust is very difficult to remove by the general blow method. High pressure ionization air flow is used to remove dust and dust at the same time. 1. plastic ABS coating The properties of the plastic ABS coatings are listed in Table 3. Table 3 properties of plastic ABS coatings project AP-1 plastic black lacquer Plastic - varnish Plastic - colored enamel Acrylic metal flash paint Acrylic color transparent paint Characteristic Dry at normal temperature, hard and wear-resistant coating, moisture proof The film is bright, hard and wear-resistant, and the adhesion is good The paint film is brightly colored, water resistant, wear-resistant and good adhesion The film is bright, wear-resistant, and with good adhesion The film is bright and transparent and has good wear resistance. purpose Plastic coating for ABS, PS, PVC and HIPS Plastic coating for ABS and PS Plastic coating for ABS and PS ABS plastic coating ABS plastic coating Coating process of 1. ABS plastic coating PC/ABS resin has been widely applied in the field of consumer goods, such as building materials, pipes, sheets?or?sheets, which is now replaced by a cheaper PVC resin. ABS resins are used in building related fields, including extruded sheets for sanitary appliances, such as bath boxes, swimming pool linings, etc., and pipes and pipes for injection molding, and a small number of extruded telephone cable lines are produced. Jia Xin plasticizing material market trend followed by force, committed to development and promotion of ABS materials, launched a series of excellent comprehensive performance and technical performance of ABS automotive materials, the development of many new ABS composite materials, such as high impact resistance, flame retardancy, appearance, color, used for end users to provide full support and help and continue to provide new solutions. Main origin The world's largest manufacturer of ABS five are: Taiwan China CMO company, the total capacity of 1 million 250 thousand tons / year, of which 1 million tons / year, Zhenjiang Tainan plant unit of 250 thousand tons / year; the total production capacity of 930 thousand tons / year of Bayer LG; chemical total production capacity of 700 thousand tons / year; GE Plastics GE total capacity of 650 thousand tons / year; BASF production capacity of 560 thousand tons / year, five enterprises accounted for 55.6% of the world's total production capacity. Five major production enterprises have accounted for more than half of the global ABS capacity. Due to the large gap of ABS supply in the mainland of China, a large number of products have been exported to China. At the same time, Chi Mei and LG have set up factories in mainland China and have the intention of expanding [3].
