Silicone oil - a linear polysiloxane that remains in a liquid state at room temperature, is a silicone product with a wide range of products and a wide range of applications. Classified according to the different substituent groups on the polysiloxane chain. Silicone oil can be divided into: methyl silicone oil, hydrogen silicone oil, vinyl silicone oil and polyether modified silicone oil, phenyl silicone oil, hydroxy silicone oil, fluorosilicone oil, amino silicone oil, ethyl silicone oil and other types.










Silicone oil consumption structure and application field




At present, silicone oil is mainly used as high-grade lubricating oil, anti-vibration oil, insulating oil, defoaming agent, mold release agent, polishing agent, release agent and vacuum diffusion pump oil; silicone oil emulsion can be used for car tire glazing, instrument panel light And other uses.

Whether it is long hair,


a smooth, shiny hair,


Probably the pursuit of every beautiful little fairy.














but,


As a non-mainstream person,


How can hair now hide from the hot dye of washing and cutting?


One year old and one year old, year after year...


Can you still be proud? nonexistent!


So I went further and further on the road of destruction...


Is there a better way than not to dye it?






- Of course!


Then,


What is the secret between silicone oil and shampoo?








[The role of silicone oil in shampoo]


The outermost layer of the hair is hair scales, the scales are very fragile, shampooing, combing and hot dyeing will make the scales curl up and open, which makes the hair look rough, easy to knot, and combing is very inconvenient. As a softener, silicone oil acts in the shampoo to fill the gap between the scales, making the hair more supple and reducing knotting.

Silicone oil emulsions are widely used in personal care products and cosmetics. Appropriate addition can not only improve the texture of cosmetics, but also make the cosmetics have smooth, sunscreen and UV radiation resistance, and good breathability. Moreover, due to the special hydrophobic properties of the silicone oil, the cosmetic can also be made waterproof and sweat-proof.














2 textile industry






Silicone oil can be used as a softener, lubricant, waterproofing agent and finishing agent for fabrics in the textile and garment industry.






 In order to meet the high-end needs of textiles, chemical companies are also exploring the potential applications of silicone oils, and continuously developing silicone oils that can be used in combination with various functional additives such as water repellents, flame retardants, antistatic agents, and fixing agents. In addition, in order to improve the performance of the fabric, there are silicone oils which can be used together with dyeing; silicone products which can improve the hand of the fabric, and silicone-based deepeners which give the fabric an excellent hand.


In addition to enhancing the function of textiles as an additive in textiles, silicone products will also be applied to other areas of textiles, such as the combination of silicone and polyurethane to form a coating of fabric; the polymerization of silicone and acrylic to form a fabric; silicone A water-repellent coating or the like which forms a surface of the fabric in combination with organic fluorine.

3 industrial machinery




Damping damping
Silicone oil is widely used in motors, electrical appliances, and electronic instruments as an insulating medium for temperature resistance, arcing resistance, corrosion resistance, moisture resistance, and dustproofing, and is currently used as an impregnating agent for transformers for transformers, capacitors, and televisions. Used as a liquid shockproof and damping material in various precision machinery, instruments and instruments. Since the vibration damping performance of silicone oil is less affected by temperature, it is often used in the case of strong mechanical vibration and large changes in ambient temperature, such as: instruments for airplanes and automobiles. It is used for shockproof, damping, and stable meter readings. It can also be used as a liquid spring and in the landing gear of an aircraft.






Thermal conduction
Thermal grease is a kind of heat transfer medium which is widely used at present. It is a kind of ester which is formed by using silicone oil as raw material and adding a thickener and other fillers after heating, decompression, grinding and the like. The substance has a certain consistency and no obvious graininess. The thermal grease works at temperatures ranging from -50 ° C to 180 ° C and has excellent thermal conductivity, high temperature resistance, aging resistance and water resistance. During the heat dissipation process of the device, after heating to a certain state, the thermal grease exhibits a semi-liquid state, fully filling the gap between the CPU and the heat sink, so that the joint between the two is tighter, thereby enhancing heat conduction. Under normal circumstances, thermal grease is insoluble in water, is not easily oxidized, and has certain lubricity and electrical insulation. Similar to thermal grease, thermal silica gel is also chemically processed by adding certain chemical materials from silicone oil. Unlike thermal grease, there is some kind of viscous material in the chemical raw materials it adds, so the finished thermal silica gel has a certain adhesive force. The most important feature of thermal silica gel is that it has a hard texture after solidification and its thermal conductivity is slightly lower than that of thermal grease.






Cutting fluid
Silicone oil is added to the cutting fluid to provide lubrication and defoaming.






Demolding
Silicone oil can be widely used as a release agent for molding various rubber and plastic products. Its advantage is that the mold release is convenient and the surface of the product is clean, smooth and the texture is clear.

4 medical and food




Polydimethylsiloxane is commonly used in medical treatment. Because of its defoaming properties, it can be used as an anti-dwelling tablet for treating abdominal distension and an aerosol for treating pulmonary edema. It can also be used as an anti-adhesion agent for preventing intestinal adhesion in abdominal surgery. , as a lubricant for gastric juice defoamers and some medical surgical instruments in gastroscopy.


Silicone oils can also be used as defoamers in the food industry.


Silicone grease is a silicone grease that is thickened with an inorganic thickening agent and is made of a variety of additives such as anti-oxidation and anti-corrosion.






what? Silicone oil is also useful in the food industry?






Silicone paper is a commonly used wrapper with a three-layer construction: a first layer of backing paper, a second layer of laminating film, and a third layer of silicone oil. Because silicone paper has the characteristics of high temperature resistance, moisture resistance and oil resistance, it is generally used for packaging in the food industry.










Silicone oil paper






5 surface treatment




Mainly used for waterproofing and antifouling of glass fiber materials. After the building materials are treated with silicone oil, the weathering resistance and water repellency can be improved. The silicone oil emulsion with 0.1% to 0.15% or higher solid content can be added to the mortar to improve the fluidity of the mortar.


Asbestos, cement, gypsum board, etc. can also be treated with silicone oil.
