Q:POM plastic flower mold how to solve?
Terms of settlement:1, the raw materials in the drying machine to fully dry and then production.2, reduce the size of the pipe, especially the nozzle temperature.3, slow down the speed of the injection.4. Adjust the position of the spray glue accordingly.
Q:The concept, classification and distinction of modified plastics and plastic raw materials.
Concept: modified plastics, refers to the base of the general plastics and engineering plastics, after filling, blending and enhancement processing method of modification, improve the performance of flame retardant plastic products, strength, impact resistance, toughness.
Q:How many kinds of plastic materials are there?
The molecular structure of thermosetting plastics is the body structure, softening also occurs in heated, can plastic into a certain shape, but is heated to a certain extent or amount of curing agent, hardened stereotypes, re heating will not soften and change the shape of the. Thermosetting plastic processing, molding, the heat is no longer softening, and therefore can not be recycled, such as phenolic plastics, amino plastics, epoxy resin, etc. belong to this kind of plastic. Thermosetting plastic forming process is more complex, so continuous production has some difficulties, but its good heat resistance, not easy to deformation, and the price is relatively low.
Q:The use of various plastic materials?!
Suitable plastic products: for general structures or wear resistant transmission parts and corrosion protection equipment. Gears, pumps, impellers, bearings, handles, pipes, motors, housings, electronic parts, clocks and watches, water tanks, freezers, refrigerators, housings, stationery, toys
Q:Why plastic is not environmentally friendly?
3. plastics are made from petroleum refining products, and oil resources are limited.4. plastic buried in the ground for hundreds of years, thousands of years or even tens of thousands of years will not decay.5., the heat resistance of plastic is poor, easy to aging.
Q:What do you mean by the release angle of plastic parts?
That is, the cup and the table top are not 90 degrees angle, and the angle between the outer wall of the cup and the table top is usually less than 90 degrees, and the wall thickness of the cup can be even or even uneven.
Q:Are there any other plastic products besides stretch?
Ductility refers to the degree of temper used. Forging material without annealing can be malleable material. Temper rolling, annealing and rolling to temper. Brittle material in the temper rolling after the degree of L is poor. The object under the action of external force can be extended into filaments and properties called ductility fracture;
Q:Scope and characteristics of plastics No. 7
Plastic No. 7 represents polycarbonate (PC), other plastic products. PC is a widely used material, especially for bottles and space cups, which is controversial because it contains bisphenol A. Experts point out that, in theory, as long as the process of making PC, bisphenol A percent into plastic structure, it means that the product is not bisphenol A, let alone release. However, if a small amount of bisphenol A is not converted into a plastic structure of PC, it may be released into the food or drink.
Q:Is the plastic case transparent or opaque?
From the convenience of speaking, transparent, easy to organize, easy to see the contents of the collection, and opaque, but need to open the view.
Q:What are the hazards of plastic oiler
Need to see what kind of plastic to fill the oil, at room temperature, PET plastic pot of oil is non-toxic, but other plastics in the oil will generally precipitate some chemicals.
