有机硅享有“工业味精”的美誉,是国民经济的重要基础原料,用途极为广泛。接下来
一起了解有机硅的生产过程。
Silicone material is the so called "industrial monosodium glutamate". It is an
important basic raw material of the whole country’s economy growth and has a wide
range of application. In the following, let us have a quick look about the production
process of silicone.
首先,购置来的金属硅块通过研磨机磨成硅粉,合格的硅粉会通过气体输送给单体合成
装置。
First of all, metal silicon block is milled into powder by miller, after that, milled
silicon will be transported to MCS reaction unit by gas.
再和催化剂、氯甲烷一起进入流化床进行气固相催化反应生成有机硅粗单体,通过洗涤
塔过滤出渣浆后,顶部得到的物料到粗单体塔进一步分离得到粗单体。
Milled silicon and methyl chloride( MCl) reacts in the presence of catalyst to produce
methylated crude MCS (methyl chlorosilanes) in a fluid bed through catalytic
reaction of gas and solid phase. Methylated crude MCS will be scrubbed to remove
fines and then fed to demethylation column to separate methyl chloride from MCS
to get demethylated crude MCS.
这期间产生的废气、废水、废渣都会被工厂循环利用,绿色处理。
Waste gas, waste water and waste solid generated during reaction will be recycled
and green treated.
粗单体是包含多种物质的混合物,必须要经过甲基单体精馏塔分离。
Crude MCS produced from reaction unit is a mixture containing multiple substance
and must to be separated by distillation column.
而这种甲基单体精馏具有分离组分多、组分相对挥发度小、分离纯度高等特点,粗单体
通过多塔分离工艺,分离出一甲,二甲等多种高纯度甲基单体产品。
The distillation column can manage multi-component separation, enable relatively
low volatility and high purity of separation, it can separate highly pure methyl
chlorosilane such as M1(Methyltrichlorosilane), M2(Dimethyldichlorosilane) etc.
通过单体精馏出来的产品,哈尔滨配音公司在二甲水解装置进行水解后又能变成氯化氢和硅氧烷,氯化
氢在氯甲烷装置中与甲醇循环回用生产氯甲烷,氯甲烷返回合成装置生产粗单体。硅氧烷可
以生产 D4(八甲基环四硅氧烷)、D5(十甲基环五硅氧烷)、DMC、107 胶、甲基硅油,供给
下游生产和外卖。
The distillated M2 is fed to hydrolyzation unit to produce siloxane and recycle HCl
gas.
Siloxane can be used to produce D4, D5, DMC, H48, PDMS oil for downstream
production and sales. Recycled HCl gas will be sent to MeCl unit to react with
methanol to produce MeCl which will go back to MCS reaction unit.
有机硅拥有耐高温、耐候等出色性能,广泛应用于航空航天、建筑、电子、个人护理、
纺织、涂料等各行各业,以及新能源汽车、高铁、3D 打印等新兴市场。尤其在许多尖端领
域,有机硅有着不可替代的特殊作用。
Silicone has outstanding properties such as high temperature resistance, weather
proof. It is widely used in all different applications, such as aerospace, construction,
electronics, personal care, textile, coating, as well as emerging market, such as green
energy vehicle, high-speed train and 3D printing. Silicone has unique functions and is
non-replaceable, especially in some cutting-edge application areas.
如今,埃肯星火有机硅已成为国内化工行业中为数不多的,哈尔滨配音公司真正依靠自主创新发展起来
的拥有自主知识产权的民族工业,成为世界有机硅工业的重要力量。
Nowadays, Chinas silicone industry has become one of the few national industries in
the domestic chemical industry, which has independent intellectual property rights
and has become an important player in the worlds silicone industry.
世界有机硅工业已进入中国时代。
The global silicone industry has entered the era of China.
