Characteristics of PC raw materials

2021-10-27

PC has high strength and elastic coefficient, high impact strength, wide range of operating temperature, high transparency and high free dyeing H.D.T., good fatigue resistance, good weather resistance, excellent electrical properties, tasteless and odorless, harmless to human body, in line with health and safety, low forming shrinkage and good dimensional stability. PC is a non-crystal engineering material, it has particularly good impact strength, thermal stability, gloss, inhibition properties, flame retardant properties and stain resistance. PC notched Izod impact strength (otched Izod impact stregth) is very high, and the shrinkage rate is very low, generally 0.1%~ 0.2%. PC has good mechanical properties, but poor flow characteristics, so the injection molding process of this material is difficult. In the choice of what quality PC material, to the product's final expectations as a benchmark. If the plastic parts require a higher impact resistance, then use a low flow rate of PC material; on the contrary, you can use a high flow rate of PC material, which can optimize the injection molding process.

In the golden autumn, I wish you happiness and good health.

2021-10-14

Today is the ninth day of the ninth lunar month Double Ninth Festival While the autumn rhyme is strong While still young With family and friends Climb with a shallow drink Sharing the Joy of Double Ninth Festival Our best wish is I have grown up, you are not old I strongly repay, you are still healthy But time waits for no man In the Double Ninth Festival Please remember to greet the elders at home The family expected. May be just a soft call Respect for the elderly starts with respect for their own elderly, that is, filial piety to their parents. A Chinese proverb says, "if there is an old man in a family, if there is a treasure," he can solve any kind of difficult and miscellaneous diseases by asking him for advice, and he is wise. He has more experience and wisdom than young people. He is the pillar of a family and a small group. Climb high and look far In the golden autumn of October, the sky is clear in Yunyuan. In the season of maple red leaves and yellow Go out with friends for autumn Climb the air fresh Let people more relaxed and happy Dongguan Jiaifa Plastic Raw Material Co., Ltd. (abbreviated as: Jiaifa), specializing in plastic raw materials, is a plastic enterprise integrating plastic raw material trade, production, research and development, color matching, and storage, and is equipped with a professional management system and R & D team., Production equipment, testing equipment, escort the needs of customers.

The performance test of plastic ABS should pay attention

2021-10-13

(1) General performance: The appearance of ABS is opaque ivory granules, non-toxic, tasteless, low water absorption rate, its products can be colored into a variety of colors, and has a high gloss of 90%. ABS has good combination with other materials and is easy to surface printing, coating and plating. ABS has an oxygen index of 18.2 and is a flammable polymer. The flame is yellow, with black smoke, burnt but not dripping, and a special cinnamon smell. ABS is a resin with very good overall performance. It has high impact strength and surface hardness in a relatively wide temperature range. Its thermal deformation temperature is higher than that of PA and PVC, and its dimensional stability is good. The fluidity of ABS melt is better than PVC and PC, but worse than PE, PA and PS, similar to POM and HIPS. The flow characteristics of ABS are non-Newtonian fluids, and its melt viscosity is related to processing temperature and shear rate, but it is more sensitive to shear rate. (2) Mechanical properties ABS has excellent mechanical properties, its impact strength is good, can be used at very low temperatures. Even if the ABS product is damaged, it can only be tensile damage and not impact damage. ABS has excellent wear resistance, good dimensional stability, and oil resistance. It can be used for bearings under medium load and speed. The creep of ABS is larger than that of PSF and PC, but smaller than that of PA and POM. The bending strength and compression strength of ABS are the poorer in plastics. The mechanical properties of ABS are greatly affected by temperature. (3) Thermal performance ABS is an amorphous polymer with no obvious melting point; high melt viscosity, poor fluidity, poor weather resistance, and UV light can cause discoloration; the thermal deformation temperature is 70-107 ℃ (about 85), and the products can be annealed. Increase by about 10 ℃. It is sensitive to temperature and shear rate. ABS can still show some toughness at -40 ℃ and can be used for a long time in the temperature range of -40 ℃ to 85 ℃. (4) Electrical properties ABS has good electrical insulation and is almost unaffected by temperature, humidity and frequency, and can be used in most environments. (5) Environmental performance ABS is not affected by water, inorganic salts, alkali alcohols and hydrocarbon solvents and a variety of acids, but soluble in ketones, aldehydes and chlorinated hydrocarbons, by glacial acetic acid, vegetable oil and other erosion will produce stress cracking. Performance testing is an automated test tool to simulate a variety of normal, peak and abnormal load conditions to test the performance indicators of the system. Jia is a collection of plastic raw materials trade, production, research and development, color, storage in one of the plastic enterprises. Can provide customers with plastic raw materials related integration solutions.

Precautions for the use of ABS plastic

2021-10-12

1. Startup and shutdown for flame retardant grade ABS in order to prevent the decomposition of flame retardant, there are strict requirements. When starting up, the barrel should be cleaned with general-purpose ABS before processing. Before shutdown (referring to those who shut down for more than 20 minutes), on the one hand, the temperature of the barrel must be reduced to below 100 ℃, on the other hand, the material in the barrel must be emptied, and the barrel can be cleaned with general-purpose ABS before shutdown. Its purpose is to make the flame retardant grade ABS does not decompose. 2. The use of recycled materials for primary or secondary clean, no impurities, no decomposition of ABS recycled materials, can be crushed and used directly, can also be mixed with new materials, the mixing ratio is generally not more than 25% of the new material, so as not to affect the performance. For the regeneration of more than 5 times or add a colorant recycled materials, generally not mixed with new materials, mainly to prevent the cause of color. Whether it is a separate recycled material or a recycled material mixed with new materials, it must be dried according to regulations before it can be put into molding processing. Post-processing For the use of more demanding ABS products, in order to eliminate or reduce the internal stress, the product must be placed in a hot air circulation drying oven at a temperature of 70 to 80 ° C, processed for 2 to 4 hours, and slowly cooled to room temperature. Like other plastics, the internal stress caused by various factors in ABS products (its size can be judged according to whether the parts are immersed in glacial acetic acid solution and the length of the cracking time). However, in general, stress cracking rarely occurs. For this reason, ABS products can usually be put into use without post-processing. Performance detection Plastic performance testing technology services throughout the chemical industry, from raw material identification, chemical product formula analysis, to product production of industrial problem diagnosis, product application failure analysis, product reliability testing, can provide the most professional analysis of technical services. ABS resin combines the excellent properties of the three monomers, namely: styrene gloss, electrical properties, formability; acrylonitrile heat resistance, rigidity, oil resistance; butadiene impact resistance
