Q:How many kinds of plastics are there?
PMMA: organic glass (commonly known as acrylic). There are five kinds of transparent plastic material, and PMMA is one of the highest transparency, cutting when vinegar sour, easy deformation, can turn plastic soaked in boiling water. Disadvantages: easy to scratch the surface, low hardness, easy to crack when bending, the price is higher than ABS more than 20%.
Q:What is plastic and what is the difference between plastic and plastic?
Plastic material is the main component is made of polymer resin, synthetic resin as the main ingredients into a variety of auxiliary material or adding agent, at a certain temperature, the plasticity and movement under pressure, can be molded into shape and maintain the same shape of material under certain conditions;
Q:Does high strength polyurethane belong to plastics?
Rubber and plastic are juxtaposed terms, no one belongs to anyone.
Q:What are the raw materials used in the production of plastic products?
Common mineral water bottles and carbonated beverage bottles are made of this kind of material which can not be recycled or hot water. Its heat-resistant temperature is only 70 degrees, only suitable for warm drinks or cold drinks, high temperature liquid or heating, easy to deformation, will dissolve the harmful substances. The scientists also found that the plastic could release carcinogens in 10 months. Therefore, when the beverage bottle is used up, it should be thrown away. It should not be used as a drinking cup or used as a storage container to hold other foods, so as not to cause health problems.
Q:How to mend cracks in a plastic bucket?
Depending on the material of the plastic tub and the location of the hole:If the plastic is PP, only hot melt, the home unconditionally;If HIPS, GPPS, ABS ab.
Q:What kind of plastic bottles can be used again and again?
Plastic bottle and digital security unrelated to market rumors, some plastic bottles are safe, can be used repeatedly, and see a plastic bottle repeatedly with safe, through the identification of the bottom of the bottle. Online friends said, at the bottom of a lot of beverage bottles, bottles of mineral water has a triangular sign with an arrow that has a digital triangle, if the number of "05" or more can be recycled, and digital more safe. "The general mineral water bottle at the bottom of mark 01; general tea cup bottom plastic label 05; cream bottle at the bottom of mark of 02; the bottom of the bottle marked 02 yogurt......" This post sends out, that causes the netizen to discuss hotly, some people approve, but some people doubt its authenticity
Q:What is the low temperature resistance of plastic PS?
PS:= polystyrene (polystyrene)Material characteristics: the disadvantages are: product brittle, low impact strength, prone to stress cracking, poor heat resistance; heat resistance: 60-70 degrees, compared with other plastics, the characteristics of PS are highly transparent (light transmittance 88%-92%) and surface gloss, easy dyeing, high hardness, good rigidity in addition, there is a good water resistance, chemical corrosion resistance and processability.
Q:Is PC the same as plastic?
This leads to the appearance of it is easy to scratch, PC material is a Han Dynasty atlas, but its strength and good toughness, regardless of weight or general beat, as long as you're not trying to hit it with a stone, it is enough to longevity.
Q:What if the plastic is broken?
The screw connection is effective for thermoplastic resin products, which can be processed at high speed and can be arbitrarily shaped.
Q:Mobile phone shell or other plastic products, the internal screw column thread is injection, or?. After injection processing?
Like the battery car, the thread above is the post processing, those big thread bottle cap, such are injection molding out
