Q:Plastic pipe gas temperature 150 degrees, plastic pipe surface problems?

The most widely used plastic pipe is plastic pipe. There are many kinds of plastic pipes, which are divided into two categories: thermoplastic pipes and thermosetting plastic pipes. It belongs to thermoplastic, including PVC pipe, polyethylene pipe, polypropylene pipe, POM pipe, super high molecular weight polyethylene pipe, etc. it belongs to thermosetting phenolic plastic pipe. The main advantages of plastic pipes are good corrosion resistance, light quality, convenient molding and easy processing. The disadvantages are low strength and poor heat resistance.

Q:PE plastic bellows raw material formula (PE and PP ratio, as well as other filling)?

The additives are mostly organic additives, and they are usually analyzed by infrared, nuclear magnetic resonance and mass spectrometry. Fillers are mostly calcium carbonate, kaolin and other fillers, play a role in strengthening and reducing costs, and can be qualitatively and quantitatively analyzed by thermogravimetric analysis and fluorescence spectroscopy. After sample pretreatment, a single component, for unknown components need to go through a variety of instruments integrated spectrum, the final reduction formula, get the whole component analysis report.

Q:What are the materials for making plastic buckets? How many are there?

Domestic plastic bucket source material basically two kinds: blow molding with PE injection: PP

Q:Plastic raw materials packaging is generally divided into several categories?

1, cattle cardboard fiber bag; "such as: GPPS, HIPS CMO ABS, are using this package, he is in some plastic packaging,2, fiber bags, plastic bags, such as PP or PVC, PE and so on3, plastic bags, Exxon, Teijin etc.4, plastic bags contain tin and platinum paper, for sealing requirements or moisture absorption of the material packaging5, kraft paper bags, PBT, PET, PPS, PA and so on

Q:Plastic PPT30S add what material will increase hardness?

Technical parameters of Qilu Petrochemical PP (T30S)Project quality index test method of isotactic index% greater than 95 GB/T 2412 powder ash%, less than 0.03 GB/T 9345 tensile yield strength greater than 28 GB/T, MPa 1040 kg/m3 0.9~0.91 density, cleanness, color particle, /kg melt flow rate of 11~20, g/10min 2~4 GB/T 3682 brand name: Qilu

Q:Pollution in the production of plastic raw materials from petroleum production

Petroleum - intermediate - polymerization monomer - resin - plastic particles - plastic products, the process of the above, each will have pollutants!

Q:Is plastic bucket and plastic bottle the same raw material?

When the number of the triangle in the bottom of the plastic barrel is 5, the main component of this kind of plastic barrel is polypropylene, or PP. The melting point of this kind of plastic barrel is relatively high, reaching 167 degrees centigrade, and can be recycled after cleaning. Compared to PE plastic barrels, PP plastic barrels of heat resistance slightly better, but the higher temperature there is the risk of softening and melting, use should avoid high temperature.

Q:What's the shell of the relay? What exactly is plastic?

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:What are the specific differences between plastics and plastics?

Plastic raw materials are extracted from some oil in the most familiar part of PC material (polycarbonate) is extracted from the oil, the PC material has a gasoline burning time; ABS (acrylonitrile butadiene styrene plastic) is made from coal, ABS a soot like when burn out; POM (polyoxymethylene plastic) is made from natural gas, POM will have a very smelly smell of gas in the burn time.

Q:What raw materials do plastic color printing plants use?

PEBOPPOPS film, aluminum film and so on, the ink is usually water-based ink, polypropylene ink, etc., different films with different ink.
