Q:What materials do you use for plastic moulds?
Can ask. So, many developed countries have formed a wide range of plastic mold steel series. Including carbon structural steel, carburizing type plastic mould steel, pre hardened plastic mould steel, aging hardening plastic mould steel, corrosion resistant plastic die steel, free cutting plastic die steel, hardened plastic die steel, maraging steel and plastic mould steel with mirror polishing.
Q:How can plastics be cleaned?
This is because the principle of similar blending, grease and oil is easily mixed together, so that the dirt float to the surface. With soaked tea bags, when the tea and hot water meet, the fibers of tea will be destroyed, so that the broken fibers in tea have the role of adsorption dirt, so it is more likely to cause dirt to fall off.
Q:What is cleaner for plastic bathtub?
Use gauze to wrap up the tea residue you drink and dip in a bit of cooking oil. Gently wipe the stains from the plastic basin. After cleaning, rinse it with a little detergent, so that the basin is cleaned.
Q:What are the advantages and disadvantages of plastic packaging materials?
Have to mention here is that the plastic packaging materials of good health, for those of the pure polymer resin, plastic packaging can be said to be almost no toxicity, when we have food packaging, can be assured of the application.
Q:Waste plastics recycling plant how to solve environmental problems
Characteristics of plastics:Plastic has excellent chemical stability, corrosion resistance, electrical insulation and shock absorption, sound insulation effect is good sound insulation,, and has good elasticity, good with metal, glass, wood and other materials bonding, easy processing. In the four big industrial materials, the quantity, function, status and application range of plastics are expanding rapidly, leading a large number of metals, wood, paper and so on. They are widely used in various fields of national economy.Hazards of plastic use:However, it is because of some excellent properties of plastics that it is not easy to decay after use or consumption. It has seriously affected the ecological environment of the earth, and has aroused great concern all over the world.
Q:What plastics are environmental protection materials now?
Biodegradable plastics: plastics that can be completely broken down into low molecular compounds under the action of microorganisms. The utility model has the advantages of convenient storage and transportation, as long as the utility model has the advantages of dry drying, no need of avoiding light and wide application range, and not only can be used for agricultural film and packaging bags, but also can be widely used in the medical field. With the development of modern biological technology, biodegradable plastics have been paid more and more attention and become a new hot spot of research and development.
Q:When was plastic invented?
The main component of plastics is resin. The term was first resin secrete by animal and plant lipid and its name, such as rosin, shellac, resin is not mixed with various additives and polymer compounds. Resin accounts for about 40% to 100% of the total weight of plastics. The basic properties of plastics depend mainly on the nature of the resin, but additives also play an important role. Some plastics are made up of synthetic resins, with or without additives such as plexiglass and polystyrene.
Q:What's the difference between cans and plastic bottles?
The glass bottle can be used repeatedly and is inconvenient to carry, but there are phenomena of cleaning up, cross contamination and fraud, and people can not be relieved.Plastic bottle, glass with respect to that of oxygen and carbon monoxide permeability coefficient is large, it will lead to a chemical reaction between packing objects and packaging, packaging is also due to the oxidation of the flavor deterioration occurred, and the aging of plastic products also affect the appearance quality, beautiful appearance and practicability, and environmental pollution.
Q:Do all plastics have plasticizers?
Plasticizer is divided into toxic and non-toxic, relieved, and now the plastic basically useless toxic plasticizers, and generally do not contain phthalate two formic acid
Q:What's the advantage of a basin made of plastic?
The advantages of the plastic basin: most plastic basins have strong corrosion resistance, not react with acids and bases, low manufacturing cost, durable, waterproof, light quality, good insulation, plastic basin atlas, beautiful and convenient
