Recently, researches on defoamers havefocused on the compound of organosilicon compounds and surfactants, thecompound of polyether and organosilicon, the combination of water-soluble oroil-soluble polyether and silicon-containing polyether, etc. Agent, thecompound is one of the development trend of defoamer. At present defoamers,polyether and silicone defoamer performance is the most excellent, these twotypes of defoamer modification and the development of new varieties of researchis also more a ...

Polysiloxane defoamer with defoamingrapidly, anti-foam for a long time and safe non-toxic and so on. But it isinsoluble in water, high temperature, alkali resistance is poor, polyetherdefoamer high temperature, strong alkali resistance, but its defoaming speedand suppression bubble time are not ideal The polyether chain is grafted intothe polysiloxane chain through the condensation technology, which has theadvantage of the second kind of antifoaming agent, and becomes a defoamingagent with excel ...

Coupling agent is an important, widely usedin the field of treatment agent, mainly for polymer composites additives. Themost important characteristic of the molecular structure of the coupling agentis that the molecule contains two groups with different chemical properties. Oneis a group of pro-inorganic, easily with the inorganic surface of the chemicalreaction; the other is the pro-organic groups, and synthetic resin or otherpolymer chemical reaction or hydrogen bond dissolved in them. So the ...

To achieve a high degree of low gas evolution.Rubber: Improve product mechanicalstrength, wear resistance, wet electric ...

Coupling agent is very common in our liveschemical raw materials. In plastic compounding, the coupling agent is toimprove the synthetic resin and inorganic filler or reinforcing materialinterface properties of a plastic additive, coupling agent, also known assurface modifier. It can reduce the viscosity of synthetic resin melt in theplastic processing, improve the dispersion of filler to improve the processingperformance, thus enabling the products to obtain good surface quality andmechanical, t ...

Trichlorosilaneis an important synthesis of organic silicon intermediates, but also the preparationof semiconductor grade polysilicon and solar cell grade polysilicon of the mainraw materials. For a longtime, due to China's smaller production capacity of polysilicon,trichlorosilane is mainly used for organic silicone rubber coupling agent andother silicone materials, the amount of polysilicon is very small.Hydrogenchloride method: the method is to use metallurgical grade silicon powder as rawmat ...

For the surface treatmentof glass fiber. Silane coupling agent can improve theglass fiber and resin adhesive properties, improve the glass fiber reinforcedcomposite material strength, water resistance, weather resistance and otherproperties. In 2004 the use of glass fiber silane coupling agentaccounts for about 50% of the total consumption, which used more varieties ofvinyl silane, aminosilane, methacryloxysilane and so on.For surface treatment ofinorganic fillers. Silane coupling agent In thein ...

Silane coupling agent is a kindof special structure of low molecular weight organic silicon compounds. The general formula for RSiX3, where R representsamino, mercapto vinyl, epoxy, chloropropyl, cyano and methacryloxy groups andother groups. These groups and different matrixresins have a strong ability to react, and x represents a hydrolyzable groupsuch as halogen, alkoxy, acyloxy and the like. Silane couplingagent is trichlorosilane (HSiCl3) and with reactive groups of unsaturatedolefins in th ...

Theaction of the defoamer is to suppress and eliminate the generation of airbubbles. In general, when the viscosity of water-based ink is toohigh, PH value is low, or when the press speed is relatively fast when it iseasy to produce bubbles, if the amount of bubbles will appear larger than thedirty version. Water-based inks generally usealkali-soluble binder, the binder material is an acidic resin alkali solution. Itis an aqueous solution similar to soap, because water-soluble binders have soapc ...
