The common function of coupling agent is to establish compatibility between organic and inorganic materials. For example, to improve the dispersion of nano calcium carbonate in polymer, coupling agent and surface treatment are needed. The introduction of organic groups on the surface of inorganic materials makes it much more compatible with polymers and reduces the problems of migration, precipitation and agglomeration.This is similar to block polymer or graft polymer (such as graft maleic anhyd ...

Leather brightener is made of high-quality organic silicon. It is a water-soluble oil brightener. The leather brightener has a smooth and delicate feel (oily feeling), with high brightness and smoothness. This product is resistant to high temperature and low temperature. It does not contain solvent and does not stick to leather. It can increase the handle of leather products, make them softer and more natural, and make the leather smooth and delicate. The leather products are endowed with excell ...

Wool is one of the earliest textile fibers used by human beings. It has many excellent characteristics, such as smooth handle, good warmth retention and comfortable wearing, but it is easy to pilling. Silicone softener is widely used in wool fabric softening finishing. It can change the friction coefficient of wool fiber and improve the pilling resistance of wool fabric. However, it has poor hydrophilicity and easy to produce static electricity, which affects the wearability. The first generatio ...

surface tension of waterThe surface tension of water is 72 nm / cm at room temperature and has little change with temperature. The surface tension of these materials can be determined by the surface tension of the materials, such as water. If the water drops on the surface of plastic or lotus leaf, we call it non wetting, or poor wetting. On the contrary, if the water drops spread evenly on the surface, it shows good wetting effect. In the process of our life and production, the surface behavior ...

The amount of softener directly affects the thickness of lubricating oil film on the fiber surface. According to the oil film thickness D, the lubrication properties can be divided into fluid lubrication and boundary lubrication.The strength of lubricating film is inversely proportional to the thickness d of lubricating film. If the viscosity of lubricating layer is too large, the thickness of fluid lubrication layer will increase correspondingly, which will cause the strength of lubricating fil ...

Rigid foam refers to the foamed plastics with no flexibility, high compression hardness, high stress and a certain value, which can produce deformation and can not restore the original state after stress relief. ISO also stipulates that the foam will be compressed to 50% and the thickness of the foam will be reduced by more than 10% after the pressure is released. Its thermal insulation and mechanical properties are often used in relevant aspects. The typical products are polystyrene foam, rigid ...

Silicone pressure sensitive adhesive is a special adhesive composed of silicone resin (commonly used MQ silicone resin), silicone rubber, catalyst, crosslinking agent and other additives. Silicone pressure sensitive adhesives mainly include solvent type, high solid content type, solvent free type, emulsion type, radiation curing type, resin modified type, biodegradable type and functional type system.Due to the large amount of volatile organic compounds (VOCs) in the solvent type, the solvent vo ...

1. Structure and classification of MQ resinMQ silicone resin is a kind of silicone resin with unique structure. It is a three-dimensional spherical structure silicone grease produced by CO hydrolysis and polycondensation of organosilicon compounds containing four functional siloxane chains (SiO4 / 2, q) and silicone compounds containing single functional siloxane chains (r3sio1 / 2, m). Its molar mass is generally between 1000 and 8000g / mol. it has the state from viscous fluid to solid powder, ...

The first snow of 2020 is coming, I am waiting for you at SILIBASEIn winter in Zhejiang, snow began to fall in many places in Zhejiang last night, and some people have piled up snowmen. Last night, the cold air has entered the northern part of Zhejiang. Huzhou, Jiaxing, and Hangzhou have signed for receipts. Small partners in other parts of the province Cold Air The courier also knocked on the door one after another. With the arrival of a "quick-freezing" cold air, many places in Zheji ...
