OverviewSilane coupling agent is a kind of low molecular organosilicon compound with special structure. Its general formula is RSiX3, where R represents amino, mercapto, vinyl, epoxy, cyano and methyl propionyloxy groups. Groups, these groups and different matrix resins have strong reactivity, X represents a group that can be hydrolyzed, such as halogen, alkoxy, acyloxy and so on. Therefore, the silane coupling agent can not only interact with the hydroxyl in the inorganic substance but also wit ...

Dear customers and friends:The Dragon Boat Festival on the fifth day of the fifth month of the lunar calendar is one of the traditional folk festivals in my country. The Dragon Boat Festival is also called Duanyang Festival, Wuri Festival, May Festival, Five Days Festival, Ai Festival, Duanwu Festival, Chongwu Festival, Chongwu Festival, Noon Day, Summer Festival, and Pu Festival. It was originally a summer festival to eradicate the plague. Later, the poet Qu Yuan of the Chu State committed suic ...

According to the composition of the defoamer, it can be divided into many types, such as silicone defoamer, polyether defoamer, silicone polyether defoamer, mineral oil defoamer, tributyl phosphate defoamer, silicon Oxyane defoamer, n-butanol defoamer, etc. These are relatively common defoamers, and there are some uncommon ones, so I won't introduce them.If it is divided by industry, there are even more. Each industry has corresponding defoamers, such as water treatment defoamers, paper defoamer ...

Amino silicone oil is currently widely used in the soft finishing of cotton, linen, wool, silk and chemical fiber fabrics. After its finishing, the fabric has the advantages of softness, smoothness, plumpness, good resilience, durability, wrinkle resistance, scratching, and washing resistance. However, the general amino silicone oil has three major disadvantages: ①There is no hydrophilic group in the structure, the finished fabric has water repellency or low water absorption, and the hydrophili ...

In order to overcome the above shortcomings, the commonly used method is to modify its chemical structure. Modification methods include acylation modification, epoxy compound modification, formation of quaternary ammonium salt, etc. Organic silicon quaternary ammonium salt makes the nitrogen atom positively charged When used in fabric treatment to reduce oxidized energy and prevent yellowing, organosilicon quaternary ammonium salts are combined with fibers in two ways: one is that the positive c ...

The organopolysiloxane quaternary ammonium salt is generally synthesized by the method of first synthesizing polysiloxane and then quaternizing. When synthesizing organopolysiloxane, the method of cyclosiloxane ring-opening equilibrium polymerization is generally adopted. , The catalyst has H2SO4, KOH, (CH3)NOH, etc., and then receives functional groups (such as amine groups), and controls the amount of access groups as needed, and then performs quaternization. Quaternization of hydrogen-co ...

A composite material that uses silicone resin as a matrix, filled with fillers, or reinforced with fibers (or fabrics). Organosilicon resins are usually formed by hydrolysis and condensation of organochlorosilanes, with active groups on the molecules, which are thermosetting resins due to further curing. There are four main forms of composite materials.(1) Organic silicon glass varnished cloth, made by impregnating glass cloth with organic silicon resin and drying. Mainly used as wrapping insula ...

Cement waterproofing agent is a chemical admixture that is added to cement. When the cement hardens, it expands in volume, compensating for shrinkage and tensioning steel bars to produce prestress and fully filling the cement gap. Waterproofing agent, also known as waterproofing agent, plugging king, plugging spirit, is a new type of waterproof material, divided into organic and inorganic, and is a new high-tech waterproof product. The high-grade fatty acid mortar waterproofing agent has the cha ...

Textile brighteners are mainly used for yarn finishing and textile finishing agents. Yarn finishing is to apply textile brighteners to the finished line. The treatment of textile brighteners can produce high gloss, deeper and more vivid colors, and higher The elasticity and tensile strength. The brightener used in finishing is mainly used as an important component of textile finishing agent, the purpose is to give textiles an excellent soft hand feeling, good smoothness and gloss.Let's talk abou ...
