Liquid silicone rubber and liquid silicone

Liquid silicone or liquid silicone rubber, we often do not know whether they are looking for liquid silicone or liquid silicone rubber, or both are one thing, the purpose of this article is to answer the above questions.
 
First, a liquid silicone rubber, which is a type of silicone rubber, is present in a liquid state. However, we often refer to liquid silicone rubber as liquid silicone. In fact, many of our common daily necessities are processed from liquid silicone rubber. Such as liquid silicone nipples, liquid silicone bottles.

Liquid silicone rubber
 
There are many ways to classify liquid silicone rubber. Interested friends can look at the links. Addition liquid silicone rubber is generally colorless and transparent, and condensation liquid silicone rubber is mostly milky white, of course, they can all have color paste coloring. Liquid silicone rubber based adhesives are generally odorless. Liquid silicone rubber is mostly non-toxic, especially for daily necessities. A small amount of liquid silicone rubber can not pass the ROHS test, which is micro-toxic. These products are generally used in industrial molds. Liquid silicone rubber is widely used in silicone nipples, silicone bottles, silicone cable accessories, silicone watch belts, silicone mobile phone sets, silicone bottles, silicone bowls, silicone nose pads, silicone earplugs, silicone goggles, various silicone tubes and so on.


Liquid silicone rubber can be divided into one-component liquid silica gel and two-component liquid silica gel according to its packaging form. According to its crosslinking mechanism, it can be divided into two types: condensation type liquid silica gel and addition liquid silicone gel. Condensed liquid silicone rubber A small number of added liquid silicone rubber can be vulcanized into an elastomer at room temperature, so it is also called room temperature vulcanized silicone rubber (RTV glue for short).
Combined with the packaging form and cross-linking mechanism, liquid silica gel can be classified as follows:
1. One-component liquid silica gel:


1. Condensed liquid silicone-RTV:
(1) Deacetic acid type RTV
(2) dealcoholic RTV
(3) Deketoxime type RTV
(4) Deamidated RTV
(5) Deaminated RTV
(6) Deacetone-type RTV

2, adding liquid silicone - LTV

Second, two-component liquid silica gel:

1. Condensed liquid silicone-RTV:
(1) Dealcoholic RTV
(2) Dehydrogenated RTV
(3) Deaminated RTV
(4) Dehydroxyamine type RTV

2. Adding liquid silicone (RTV, LTV)
So is liquid silicone rubber liquid silicone rubber?
In addition to liquid silicone rubber, is there any other stuff called liquid silicone?

One product, called silica sol, is a dispersion of nanoscale silica particles in water or in a solvent. The product is a kind of inorganic silica gel, which is also in a liquid state, and is also called liquid silica gel by people in the industry.

Silica sol is a colloidal solution, odorless and non-toxic. Silica sol is a dispersion of nano-sized silica particles in water or in a solvent. Since SiO2 in the silica sol contains a large amount of water and hydroxyl groups, the silica sol can also be expressed as SiO2.nH2O.
Silica sol has the following characteristics:
1. Due to the fine colloidal particles (10-20 nm), there is a considerable specific surface area, and the particles themselves are colorless and transparent, and do not affect the true color of the covering.
2. The viscosity is low, and the water can penetrate into the place, so the dispersibility and permeability are very good when mixed with other substances.
3. When the silica sol water evaporates, the colloidal particles adhere firmly to the surface of the object, and the silicon-oxygen bond is formed between the particles, which is a good binder.

Its uses are as follows:
1. Used as a binder for various refractory materials, featuring strong adhesion and high temperature resistance (1500-1600 ° C).
2. It is used in the coating industry to make the coating firm, and it can resist dirt, dust, aging, fire and other functions.
3. For thin shell precision casting, it can make the shell type strong and the casting smoothness is high. The shape is better than that of the water glass, and the replacement of the ethyl silicate shape can reduce the cost and improve the operating conditions.
4. Silica sol has a high specific surface area and can be used in catalyst production and catalyst carrier.
5. Used in the paper industry, it can be used as cellophane release agent, photographic paper pretreatment agent, cement bag anti-slip agent, etc.
6. It is used as sizing agent in textile industry. It is used together with oil agent to treat the spinnability of wool and rabbit hair, reduce breakage, prevent flying flowers, improve yield and increase economic benefits.
7. Used as a silicon steel sheet treatment agent, a picture tube dispersant, a floor wax anti-slip, and the like.
