Q:This is the molding process of plastic products. Plastic molding process has molding, extrusion, injection molding, blow molding, spraying, calendering, roll molding, etc., each process has its own characteristics, in this inconvenience one by one detail, please understand.
This is the molding process of plastic products. Plastic molding process has molding, extrusion, injection molding, blow molding, spraying, calendering, roll molding, etc., each process has its own characteristics, in this inconvenience one by one detail, please understand.
Q:Why should I granulate before injection? What's the advantage of granulation?
Direct crushing material can also be used, but the direct crushing of the material due to uneven particle size, resulting in uneven storage process, the process becomes more unstable. And granulation, the particles are generally more homogeneous, and later injection molding process is relatively stable! As for the difference between granulation and injection: This is the two process, granulation is a number of waste plastics through melting, extrusion, in the cutting machine to cut into granular. During the granulation process, some additives can be added to improve the performance of waste plastics. Something like a toughening agent. Plastic injection is the formation of plastic products by melting the plastic material and then by pressing it into the mold. Popular to say is: injection molding is the raw material into plastic products, and granulation is to make plastic products again "raw material""!
Q:Does high strength polyurethane belong to plastics?
Polyurethane is TPU, belongs to thermoplastic elastomer, classification should belong to synthetic rubber.
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:How can plastics be broken down into harmless substances?
White pollution is one of the plastic packages that are difficult to degrade. Disposable foam tableware such as fast and we used plastic bags and so on. It is very serious environmental pollution, buried in the soil is difficult to decompose, the soil will lead to reduced capacity, if the burning causes air pollution, so I do not advocate or less with it, buy the best own tools to reduce its use.
Q:What are the codes for the plastics or plastics industries in the industry?
There are industry code query, you can check, added: 03 manufacturing, 03300 manufacturing plastic products in plastic film plastic plates, tubes, rods, wire rope, plastic manufacturing and textiles manufacturing, plastics and artificial leather;
Q:What are the hazards of plastic oiler
Phthalates, two formic acid and phenol methane, are common chemicals used in plastic products. They have carcinogenic effects on humans over a long period of time. So use plastic less food.
Q:How do I see if the plastic cup is qualified?
As a result, the identification of plastic varieties has become simple and easy, and the cost of recycling has been substantially reduced. Today, many countries in the world have adopted the SPI logo scheme. China enacted almost identical labeling standards in 1996.
Q:Do plastic products contain toxic substances?
Like PE, basically non-toxicBut some additives have low toxicity
Q:How many grades are there in the plastic block? How to divide?
UL is a plastic material standard test piece by spontaneous combustion flame after the combustion time, combustion speed, falling particle state to set the plastic material fire resistance rating, according to the level of quality, followed by HB, V2, V1, V0, 5V, VTM-0, VTM-1 and thin material grade, VTM-2, and foam material grade HBF, HF-1, HF-2.
