Q:How many kinds of plastics are there?!
General engineering plastics include: polyamide, POM, polycarbonate, modified polyphenylene oxide, thermoplastic polyester, ultra high molecular weight polyethylene, methyl amyl polymer, vinyl alcohol copolymer, etc..Special engineering plastics are crosslinked and non crosslinked. The crosslinked types are poly amino bis maleic amide, poly three triazine, crosslinked polyimide, heat-resistant epoxy tree fingers and so on. Non crosslinked types are polysulfone, polyethersulfone, polyphenylene sulfide, polyimide and PEEK.
Q:How can the strength and toughness of plastic products be tested simply?
According to the chemical composition of different plastics, the plastic reinforcing agent can improve the strength of the plastics by corresponding chemical action. Mainly used in a variety of modified plastics (including glass fiber reinforced, flame retardant, halogen free flame retardant, mineral filling, etc.) and common (including recycled) plastic. Different types of plastics are suitable for reinforcing agent, modified PP, PE, ABS, HIPS, PBT, PA, PC/ABS and other plastic varieties, in the use of a small amount of conditions, can significantly improve the mechanical strength and impact strength of plastics and plastic products. Suitable for all kinds of plastic molding methods and all kinds of plastic products. Ma'anshan Keli chemical technology development and production company.
Q:How do you dye plastics?
Dry staining dye and a certain proportion of plastic pellets into the rotating drum, and adding 0.01%~0.1% zinc stearate or white mineral oil as a wetting agent to make plastic and easy to dye binding, rotating drum to make plastics and dye mixing.
Q:EVA plastic products poisonous?
1 、 Vinyl acetate content of less than 5% EVA, its main products are films, wires and cables, LDPE modifier, adhesives and so on;2 、 the content of vinyl acetate in 5%~10% is EVA, the product is elastic film, etc.;3 、 Vinyl acetate content of 20~28% EVA, mainly used for hot-melt adhesives and coating products;EVA is made up of LLDPE (linear low density polyethylene) and acetic acid (VA).
Q:New plastic products have a strong taste, how to remove?
Adsorption method: let the plastic contact soak in the right amount of milk, vinegar, baking soda, salt water, waste tea, rice or rice water, grapefruit peel and pineapple block (good quality), liquor, dilute sulfuric acid (quality of time) and other cleaning agents, after a certain time can remove part of taste.Now the supermarket also has a lot of activated carbon air purification package sold, put plastic in it can also remove the flavor, the smaller the activated carbon particles, the better the adsorption effect. But note that carbon packs need to be removed from the sun for a period of time in order to expel toxic substances.
Q:What harm does plastic particles do to the body in the factory?
Heating inside the screw shear will release some of the lower molecular gas, especially PVC, POM, PS and other chlorine containing benzene plastic raw materials, volatile gases are harmful to human body.
Q:The working principle of plastic mould
The structure is usually composed of molding parts, gating system, guiding parts, pushing out mechanism, temperature regulating system, exhaust system and supporting parts.
Q:Can the plastic lunch box be heated by microwave oven?
Although some plastic products also say that you can use microwave heating, such as "5" PP material.But my advice is not to use plastic as much as possible. After all, in such a hot, complex electromagnetic environment, no one can guarantee that the molecules of the plasticizer are not diffused. I suggest you still use high temperature resistant glass or ceramic products!
Q:Do plastic products contain toxic substances?
Can not say both, more in favor of ystm's statement.Some plastic products are non-toxic, such as water cups, etc., but some plastic products are poisonous, for example, plastic bags will not be solved.Still have specific plastic concrete analysis, is.I work in Tai'an modern plastics Co., Ltd., mainly providing plastic geogrid and other materials
Q:How many grades are there in the plastic block? How to divide?
Flame retardant grade bottom HB:UL94 CSA and C22.2 No 0.17 standard, requirements for 3 to 13 mm thick sample, the burning rate is less than 40 mm per minute; less than 3 mm thick sample, the burning rate is less than 70 mm per minute; or extinguished in 100 mm signs before.V-2: the flame was extinguished in 60 seconds after the two and 10 second combustion test of the sample. A fire can fall off.V-1: the flame was extinguished in 60 seconds after the two and 10 second combustion test of the sample. No fire can fall.V-0: the flame was extinguished in 30 seconds after the two and 10 second combustion test of the sample. No fire can fall.
