The difference between silicone rubber and silicone rubber
"Silicone" this word we all heard of, but what exactly is silica gel?
Start very long time contact "silicone" this industry since my understanding of the word "silicone" are very fuzzy. Go online to see information, some people say that the silica gel is silica hydrate, someone said silicone is a synthetic rubber; silica gel English translation also has many kinds, several major is "silica gel", "silicone", "silicon rubber," said the lower the credibility of data more and the truth now on the site, the a lot of things is really a confused account. Today, we first analyze the two words "the simplest silica gel" and "silicone rubber", have a look what is the relationship between the two of them.
If by some chemical books called "silicone", because it is the condensation of silica, the molecular formula is mSiO2 H2O. The "gel" is a highly active adsorption material, belonging to the non crystalline solids, insoluble in water and any solvent, non-toxic and tasteless, stable chemical property, in addition to alkali, hydrofluoric acid does not interact with anything. We often say that the augmentation rhinoplasty, breast filled with silica gel is the kind of silica gel
But in the mold industry, silicon dioxide we mentioned "silicone" is usually not mentioned above the hydrate of silica gel. The silica gel mould industry usually mean a polysiloxane, said simply, "silicone mold industry" is a kind of synthetic rubber, because of containing silicon atom components so called silicon rubber, and is referred to as a "silica gel". Mold industry "silicone" variety, use different. As for the properties of the products according to the different raw materials have a large gap, but in general this "silicone" (specifically silicon rubber) in the future, showing a trend of replacing rubber.
We mention "silicone" usually is not simply refer to the condensation of silica in many cases, silicified synthetic rubber is not to say that the mold industry above. But the above two categories of products are called "silica gel". At this time we again "silicone" divided into organic and inorganic silica gel silica gel. The first "silicone" - SiO2 inorganic silica gel is mentioned hydrate. Silicone elastomer containing mold industry because of containing hydrocarbon groups called organic silica gel, but in some places about "silicon rubber" would regard it as the balance between organic and inorganic compounds, but more production of silicon rubber manufacturers still boasts the production of silicones.
From the above three kinds of situation, the concept of "the word of silica gel" confused, but unfortunately, so far no state expressly called. When we hear the word "silicone" must understand is silica or silicon containing synthetic rubber, or in the final analysis is inorganic silica or organic silica gel.
Here it is necessary to mention a few words about and "silicone" Name: silicone rubber, silicone rubber, silicone. The above relationship between silicone rubber and silicone have said, silica gel difference and contains silicon rubber, silicone rubber is "silicone" organic "inside the silica gel". "Silicone" RTHK crooner, called "silicone" in mainland China, then in accordance with the mainland "silicone" confusion of names, silica gel is a confusing term. Silicone is silicone transliteration, usually we say he is "silicone", what is the silica gel?
To sum up, when we refer to "to have a knowledge of his general concept of this word when silica gel", the most important is not to see what his name is, it is important to see he is used to do what, what is his chemical structure. At the same time really calls for the early introduction of a standard call method.
