Q:What plastic material has great impact resistance?

The ability of metal materials, machinery parts and components to resist impact damage is called impact strength.

Q:PVC what chemicals do you need for plastic surface treatment?

The commonly used techniques: solvent cleaning (skim), corona treatment, short wavelength ultraviolet radiation treatment, sandpaper treatment, sandblasting processing, plasma etching, chemical etching, heat treatment etc..

Q:I made of plastic raw materials accessories containing benzene, how to remove the teacher, please enlighten!

Benzene is generally not used as a plastic processing aid, even if mixed with a little, the plastic molding process in the high temperature also make it has long been volatile.

Q:Do you have plastic materials that are low in price instead of ABS?

The H series of PP sells for only $13.5, and /KG and ABS are lower.

Q:What is Ms plastic material?

Copolymerization of styrene and methyl methacrylateMS resin is commonly used transparent plastic raw materials, general injection molding and extrusion molding, transparency of nearly PMMA, for optical components / toys / lampshades, lighting, /OA accessories / food containers / household appliances / building materials, etc.

Q:Characteristics and uses of CA plastics

Commercially available products can be divided into general cellulose acetate (acetyl - 37% - 40%). Plasticizers are often added as injection molded parts, such as toothbrushes, brushes, etc.. Cellulose acetate with a high acetyl content (40% to 42% acetyl), white, granular, powdery or cotton solid. The light stability, not easy to burn, in dilute acid, gasoline, mineral oil and vegetable oil in stability, swelling in chloroform, insoluble in acetone, methyl acetate, can dilute alkali erosion, has advantages of toughness, transparency, good gloss, good melt fluidity, easy molding. Dichloromethane homogeneous method using refined cotton linter and acetic acid with acetyl sulfate as catalyst, esterification, hydrolysis in the presence of dichloromethane solvent, can be combined with cellulose acetate acetic acid content in 60% + 0.5% range. The traditional method is to use dry cotton, acetic acid in the presence of catalyst activation, sulfuric acid, acetic acid and acetic anhydride with mixture of acetylation, then adding dilute acetic acid hydrolysis to belong to the degree of substitution, and catalyst, precipitation, acid washing, rice drying. After partial hydrolysis, cellulose acetate is called two, and the degree of esterification is 220~270. Without hydrolysis, that is, the degree of esterification, the gamma value of 300, said three cellulose acetate. Two cellulose acetate plastic handle, can do all kinds of tools of computer and typewriter alphanumeric keys, phone chassis, car steering wheel, textile equipment parts, radio switch and insulation, pen, spectacle frame and lens, toys, daily necessities, but also do desalination membranes. Three cellulose acetate, high melting point, can only match into solution processing, used as a movie film, X film, light film, electromagnetic diaphragm insulating tape, transparent container, the silver zinc battery.

Q:What can recycled plastics do?

Can replace some wooden products; can be used to make all kinds of plastic bags, barrels, pots, toys and other plastic products, living utensils. Recycled plastic granulator, plastic prospects, turn products (plastic particles) a wide, plastic enterprises demand, a medium-sized agricultural film factory, in need of more than 1000 tons of polyethylene particles, a medium-sized shoe factory in need of more than 2000 tons of PVC particles, smaller private enterprises, with particles in years more than 500 tons, so the plastic particles in a large gap, can not meet the demand, so the plastic manufacturers, sales of excellent, excellent benefits.

Q:Pollution in the production of plastic raw materials from petroleum production

Petroleum - intermediate - polymerization monomer - resin - plastic particles - plastic products, the process of the above, each will have pollutants!

Q:How are plastic products made? What is the raw material of plastics?

Plastic products are divided into: injection molding, blow molding, spray molding, blister, and die casting. Plastic material is oil. It must be done at a high temperature. The mold you call is usually steel.

Q:What material is good for plastic bellows?

In the next case, it is recommended to use PP (polypropylene) bellowsNo strong acid and high concentration of oxidant in the environment; in more than 80 degrees Celsius in the environment of soluble in benzene, toluene and other aromatic hydrocarbons and chlorinated hydrocarbons in oil absorption; for most stable, small amount of mineral oil and vegetable oil.Mainly used in the temperature range of -20 to 120 degrees Celsius environment; used in automobiles, motorcycles and other motor vehicle wire harness sheath; also used for household appliances, precision machine tools and other equipment wiring wire sheath.
