Invention of plastic
Plastic - The word comes from the Greek (plastikos), meaning suitable for molding, that is, the plasticity in the manufacturing process, allowing them to be cast
Make a variety of shapes. The invention of plastic can be called a masterpiece of mankind in the 20th century, after more than 100 years of development, plastic has been everywhere It has become an indispensable raw material for modern civilized society.
Paxsing
"Paksin" was the first to be discovered - growing plastic. In the 1850s, English chemist Parkes was researching collodion processing methods,Accidentally mixed collodion with camphor, creating a. A hard material capable of bending. And named it 'Paksin'. Parkes utilization"Paxine" made everything from combs to buttons to jewelry, and people loved it.
celluloid
In the 1860s, Hiatt improved the manufacturing process of the "Paksin" and renamed it "Celluloid". "Ceruloc was originally used in the manufacture of billiard balls, but as the plastic market continued to expand, "Ceruloc" was made into various types
Product. "Celluloid" is a man-made plastic, with flammable characteristics, so its product production range is limited.
Invention of polyethylene
In 1933, Reginald Gibson and Eric Fawcett of ICI found that ethylene can be polymerized into polyethylene under high pressure.This method was known as the high-pressure method, and industrial production began in 1939. Polyethylene (PE) then evolved into low-density polyethylene(LDPE) and high-density polyethylene (HDPE) in two forms. In the early 1950s, the American Phillips Oil Company discovered chromium oxideAs a catalyst, ethylene can be polymerized to produce high-density polyethylene under medium pressure, and industrial production was achieved in 1957. In the '60s,Canada's DuPont company began using ethylene and a-Low density poly (B) field was prepared from olefin by solution method. PE is cheap, flexible, attached and resistant to chemical corrosion. LDPE is used in the manufacture of films and packaging materials HDPE is mostly used to make containers, pipes and auto parts.
Our company uses polyethylene products
Zhongshang huangpu guoyu plastic products factory The main business of the division is the plastic industry, but in the choice of materials will choose polyethylene, The reason is its Polyethylene odorless, non-toxic, feel like wax, has excellent low temperature resistance (minimum use temperature can reach -100~-70°C), good chemical stability, resistance to most acid and alkali erosion (not resistant to acid with oxidation properties). Insoluble in general solvents at room temperature, low water absorption, good electrical insulation.. This is a better guarantee for the customers who buy our products,More importantly, polyethylene is an environmentally friendly material, and environmental pollution in modern society is becoming more and more serious. Japan disregards international restrictions on the discharge of nuclear waste, which damages the ecological environment. What we can do is to do our best to protect the environment in which we can survive
