Q:Plastic products 2 can hold hot thing?
At present, many plastic products, with colorless and transparent special food bags of food is good, no other harm, opaque, or colored plastic bags are not packaged food, agricultural film is seemingly transparent, colored, is very light. It is not a packaged food product.
Q:What is the most effective way to reduce the environmental pollution caused by plastic bags?
First, strengthen management.Two, prohibit the use of disposable biodegradable plastic packaging.Three, forced recycling.
Q:Has the plastic bottle been poisoned for a long time?
01 stands for PET (polyethylene terephthalate), most commonly used in the manufacture of mineral water, carbonated drinks and other bottled beverages. As we all know, the beverage bottles made of this material can not be hot water, only suitable for warm drinks or frozen drinks, high temperature liquid or heating, it is easy to deformation, the dissolution of harmful substances. Scientists also found that the use of the plastic could release carcinogens after more than 10 months. Therefore, it is recommended that the beverage bottle be discarded and no longer used as a water container or a storage container.
Q:What is the shell of the relay? What exactly is plastic?
Other crosslinked plastics include unsaturated polyester, epoxy resin, phthalic two, diallyl resin, etc.. In thermoplastic resins, the molecular chains of resins are linear or branched, with no chemical bonds between the chains, and soften the flow when heated. The process of cooling hardens is a physical change. The first heating thermosetting plastics can be softening, heated to a certain temperature, chemical reaction and curing a chain to harden, this change is irreversible, then again, when heated, can no longer become soft flowing.
Q:Is there a difference between recycled plastics and new ones?
Polyethylene: the performance of polyethylene has decreased after regeneration, the color yellow. After several extrusion, the viscosity of HDPE decreases, and the viscosity of LDPE increases.Polypropylene: when regenerated at one time, the color is almost constant, and the melt index rises. More than two times the color increased, the melt index is still rising. After regeneration, breaking strength and elongation decreased, but no problems in use.
Q:Mobile phone shell or other plastic products, the internal screw column thread is injection, or?. After injection processing?
High grade mobile phone, screw hole is in the beer shell, directly on the mold set of beer out. Ordinary mobile phones use a self tapping screw, that is to say, when the beer comes out, it is a light blind hole and has no thread.
Q:Can a plastic water cup be boiled in general?
There are Tupperware color series of water glass is a color, which shows that in the process of plastic is added to the color masterbatch, it is recommended that the cup as little as possible.In view of the above, buy a plastic cup to buy colorless, can not be hot water use.
Q:What are the benefits of plastic bags? What's the disadvantage?
Advantages of plastic bags: the invention of plastic bags brings convenience and sanitary life for human beings. The emergence of plastic bags will also reduce food waste, the nature of the fungusproof mold also protected the health of human beings, plastic bags are used instead of other packaging materials such as paper, glass, cans, etc., to reduce energy loss;
Q:Plastic products in the injection process should pay attention to what?
When the material is formed, the molten material contacts the cavity surface and the outer layer is cooled immediately to form a low density solid shell. Because of the poor thermal conductivity of plastic, the inner part of the plastic part is cooled slowly to form a large solid layer with high density. Therefore, the wall thickness, cooling slow, high-density layer thickness is large contraction. In addition, the layout and number of inserts have direct influence on the direction of material flow, the density distribution and the shrinkage resistance. Therefore, the characteristics of plastic parts have great influence on the shrinkage size and direction.
Q:Why don't you put the plastic bags in the fridge?
Plastic bags will also release plasticizers, contact bags of food will intake, and cause many hazards to human health.
