Q:POM plastic flower mold how to solve?
Causes of plastic mould material bloom:A, plastic raw materials contain moisture, resulting in plastic hydrolysis after heating.B, molding temperature is too high, plastic decomposition!
Q:How to classify waste plastics? Identification methods?
In general, transparent plastic bags, such as common use fresh-keeping bag, belonging to recycled plastic bags, and opaque plastic bags, such as markets with color and black plastic bags, garbage bags, transparency, flexibility is poor, belongs to Unrecyclable plastic bags. The reason is that opaque plastic bags are made from waste plastics and have lost the value of recycling.
Q:How to mend cracks in a plastic bucket?
AB is a nickname for the two liquid mixed hardening glue, the glue is a liquid, a liquid hardener, two feed to hardening, is not required by the temperature should be hard ripening, so it is a kind of adhesive curing at room temperature, the model is sometimes used to do. Generally used in industry.
Q:Is PC the same as plastic?
PC should be a kind of plastic, PC, its strength can meet the needs from mobile phones to bullet proof glass, the disadvantage is that compared with metal, lack of hardness
Q:Can plastic bottles drink hot water?
The plastic bottles or other plastic appliances of this material are mainly used for microwave ovens, special plastic tableware, some bottles and daily drinking cups.No. 5 plastic polypropylene (PP) is the most heat-resistant plastic. Generally speaking, this kind of plastic material is milky and translucent, and the color is uniform. Some also add a transparent (harmless to human body) to make it all transparent. Can be reused after cleaning.  Be careful not to choose the smell or colour. Because the pure PP plastic has no odor, and the addition of color is often to cover the defects of the product itself.
Q:How do I see if the plastic cup is qualified?

At present, this kind of material has few containers for packing food. Never use it if it is in use. "
Q:Plastic products in the injection process should pay attention to what?
Plastic thermoplastic plastic molding process because of the presence of the crystalline volume changes shape, inner stress, frozen in plastic residual stress in the large, strong molecular orientation and other factors, so compared with thermosetting plastic shrinkage shrinkage is large, wide range, obvious direction, also after molding the shrinkage, annealing or conditioning after shrinkage generally than thermosetting plastic.
Q:How can plastic paint be used to prevent paint falling off?
In addition to electricity and dust: plastic products are insulators, surface resistance is generally around 1013, easy to generate static electricity. After electrification, it is easy to absorb small dust in the air and adhere to the surface. It is very difficult to remove dust by electrostatic adsorption by general blowing method. The effect of using high pressure ionized air flow and removing dust at the same time is better.
