PVC resin is the second largest raw material in the world, and there are many kinds of PVC resin on the market. Today, let's introduce the SG series. SG represents the PVC resin produced by suspension method,

The density of pure titanium at room temperature (25 ℃) is 4.505g/cm3. melting point of titanium is (1668 ± 5) ℃. boiling point of titanium is (3260 ± 20) ℃. the specific heat capacity of titanium at 20 ℃ is 500J/(kg · K).

There are many production processes of PVC. According to the different monomer vinyl chloride, the production processes are mainly divided into calcium carbide method and ethylene m

Differences in PVC production technology. There are two production processes of PVC, one is chlorination process, the other is acetylene process.

According to Vietnam's 《Business report》, in the first 11 months of 2022, the exportation of Vietnam rubber is around 1.86 million tons, value 2.93 billion US dollars, increased 9.1% and 3% year on year respectively.

Polypropylene (PP), as one of the five general plastics in China, is widely used. Plastic woven bags, films on the outside of packaging materials, masks, non-woven protective clothing, wave buckets inside washing machines, and car bumpers are all made of polypropylene. It is understood that at the beginning of 2022, the planned new capacity of the industry statistics is about 7.35 million tons. Up to now, 2.8 million tons have been put into production in the first half of the year and 1.8 million tons in the second half of the year.

The capacity utilization rate of PVC manufacturers increased by 0.88% month on month to 71.16%, a year-on-year decrease of 4.32%; Among them, calcium carbide PVC increased by 0.67% month on month to 68.59%,

Polyvinyl chloride, short for PVC, It is the second largest industrial raw material in the world. There are a various of brands and types of PVC in China nationwide. Qilu, a large manufacturer in China, it’

According to the PVC industry, there is no big difference between the application fields of ethylene PVC and calcium carbide PVC, but the production process is different.

As opening up to the control of epidemic, this coating is popular in market! Nowadays, the government published "20 rules for epidemic prevention and control",the prevention measure not only involve taking face-mask,

The International Energy Agency (IEA) said that oil prices may rise next year as western countries' sanctions squeeze Russia's oil supply and market demand may exceeds previous expectations.

据俄罗斯《专家》周刊在12月19日报道，廉价石油时代已经终结。The era of cheap oil has ended, according to a report on the website of the Russian weekly Expert on December 19.在很长一段时间内，需求将大于供应。For a long time, demand for oil will exceed supply.

As the most widely used and most productive industrial raw material PVC in the world, it is necessary for you to understand the development history of PVC. PVC was discovered by V. Lenio in 1835. PVC was discovered twice in the 19th century, once in 1835 by Henri Victor Regnault and the other in 1872 by Eugen Baumann. In 1912, Fritz Klatte, a German, synthesized PVC and applied for a patent in Germany. PVC was industrialized in the early 1930s. Since the 1930s, for a long time, the output of PVC has been ranking first in the world plastic consumption. In the late 1960s, polyethylene replaced PVC. Although PVC plastics now rank the second, its output still accounts for more than a quarter of the total plastic output.

Polypropylene (PP) is a thermoplastic resin with the lowest density, which can be divided into homo polypropylene (PP-H) and co polypropylene. Among them, co polypropylene can be divided into block (impact resistant)
