Silicone cigarette case, silicone bath brush is made of silicate polycondensation, avirulent insipidity, chemical performance is very stable, not any response from the acid and alkali salt.
Because the silicone is colloid structure, has a number of microporous and, for water has a strong absorption ability.
So silicone cigarette case, silicone bath brush can be used as food, medicine, daily necessities of the desiccant for external use only, because the silicone is after refining of raw materials production and sterilization, and won't have side effect to human body.
Reproduced in organic silicon products production capacity of ten thousand tons of the highest in the world, 68, in the struggle of several generations, silica gel products industry in the domestic chemical industry one of the few truly rely on independent innovation, developed with independent intellectual property rights of industry, both in technology, and made remarkable achievements in the size, to become the world's organic silicon industry an important force to be reckoned with.
But until the 70 s generation at the end of the silicone industry in China has been in the initial stage.
Polymer production capacity and only dozens of tons to hundreds of t, organic silicone products are expensive, mainly for military or used in some special industries.
The implementation of the reform and opening up policy, make the world manufacturing industry to a large number of transfer in our country, promoting the extensive application of organic silicon products in our country, to the organic silicon material industry has brought the development of the spring.
Organic silicon research and industrialization in our country comes from at the beginning of the 20th century 50 generations.
1951, the heavy chemical industry of Beijing experiment so Yang Dong cochrane researchers led by grignard method the synthesis of organic silicon monomer and silicone resin, pioneered and application research of silicone industry in China.
In the 80 s generation, jiangxi, Shanghai xinghuo chemical plant resin factory, jinan petrochemical factory, bengbu silicone factory
, zhejiang civilized silicone factory, sunup company calcium carbide plant and natural gas in sichuan and other 16 units successively built methyl monomer production plant, a total capacity of up to about 20000 t/a.
But insufficient supply of methyl monomer is still serious in China.
Under the market economy environment, some methyl monomer production enterprises because of outdated technology or industrial structure adjustment out of the field;
And spark chemical plant, xinan chemical industrial group co. , LTD and jilin petrochemical company backbone enterprises, speed up the development pace, some organic silicon downstream products production enterprises and related industry also join the ranks of methyl monomer production plant construction.
In the expansion of the scale of production at the same time, China's organic silicon production technical level has greatly increased.
20, hot vulcanized silicone rubber products and the actual production of room temperature vulcanized silicone rubber are respectively more than ten thousand tons, completely broke the foreign products occupying most of the domestic market, in terms of high temperature and room temperature glue also implements the technology and large quantities of export products.
By the end of 27, the methyl monomer production capacity of 2. 7 million tons.
At present, the domestic about the development of stealth materials has built up a relatively perfect system, except for some military enterprise, many joined the team in colleges and universities, such as Harbin industrial university, northwestern polytechnical university, Beijing institute of aviation materials, Qingdao university of science and technology, etc.
Silicone commodities, this is the dow secondary improve organic silicone product price this month.
On July 1, dow chemical has just raised the silicone sealant, potting glue, silica gel, thermal interface materials, such as electronic adhesive, price increases of up to 15%!
Today announced rises again, and is a bigger building organic silicon products for share.
Fluorine rubber has multiple varieties, respectively with good acid resistance, oxidation resistance and oil resistance, solvent resistance performance.
In almost all of the acid medium and some oil and solvent used in the long-term use of temperature below 200 ℃.
Propellant is to send a rocket out of the atmosphere and the key to power spacecraft in space, it is a kind of when burning can quickly generate a large amount of high temperature gas chemicals, by regularly release energy, combustion gas, push the rockets and missiles.
Whether real or accurate 3 d figure, after the software has some differences in data conversion between, some even damage data, lead to can't open the image file, this kind of situation usually it's best to be open to the same software.
