Principles of selection of adhesives

Principles of selection of adhesives

(1) Consider the type, nature and hardness of the bonding material;(2) Consider the shape, structure and process conditions of the bonding material;(3) Consider the load and form (tensile force, shear force, peeling force, etc.) borne by the bonding part;(4) Consider the special requirements of materials such as electrical conductivity, thermal conductivity, high temperature resistance and low temperature resistance.

Introduction of hydroxyl silicone oil for softener

Introduction of hydroxyl silicone oil for softener

After matching dimethyl hydroxy silicone oil and dimethyl hydrogen siloxane, a silicone emulsion is made for fabric finishing, which can react to form a silicone film covering the surface of the fabric. This very thin silicone film has a good covering strength, so that the treated fabric is soft and has the characteristics of waterproof. In order to obtain a better finishing effect, it is generally necessary to transform the thermodynamically stable spiral configuration of hydroxyl silicone oil into a linear extended chain configuration above 140 ℃, which can be exhibited on the surface of the fiber in the form of a monolayer. The more suitable conditions are drying at 90 ℃ and then baking at 140 ℃ for a short time. Hydroxy silicone oil after baking in the fabric surface to form an elastic film, the film is also insoluble in the lye, there is a good wash.

Vinyl trimethoxysilane Application field

Vinyl trimethoxysilane Application field

This product is an important crosslinking agent for crosslinking polyethylene in the manufacture of wire and cable insulation and sheath materials. Compared with general peroxide crosslinking and radiation crosslinking, its crosslinking process has the advantages of simple equipment, less investment, easy control, wide density range of polyethylene, suitable for the production of fan-shaped cores with special shapes, and high extrusion speed. Because silane crosslinked polyethylene has excellent electrical properties, good heat resistance and stress cracking resistance, this product is widely used in the manufacture of wire, insulation and sheath materials.

Development Status of Silicone Pressure Sensitive Adhesive

Development Status of Silicone Pressure Sensitive Adhesive

Silicone pressure-sensitive adhesives are solvent-based and heat-curing. Solvent-based silicone pressure-sensitive adhesive is usually heated or naturally dried for a period of time to allow the solvent to volatilize, which can have pressure-sensitive adhesive, but this type of pressure-sensitive adhesive can be dissolved by the solvent. Heating curing silicone pressure sensitive adhesive usually needs to be heated to more than one hundred degrees to form a pressure sensitive adhesive performance. If you need to use isolation film, with ordinary pressure sensitive adhesive isolation film can be.

Advantages of silicone defoamer

Advantages of silicone defoamer

Due to the special chemical structure of silicone oil, it is neither soluble with water or substances containing polar groups, nor soluble with hydrocarbons or organic compounds containing hydrocarbon groups. Due to the insolubility of silicone oil to various substances, it has a wide range of applications, even if it is defoamed in water system, it can be used in oil system.

Silicone defoamer type introduction

Silicone defoamer type introduction

Polyether modified silicone is a polyether-siloxane copolymer (referred to as silicone ether copolymer) made by introducing polyether segments into siloxane molecules. Polyether modified silicone defoamer is a new type of high efficient defoamer which combines the advantages of both. It is a defoamer composed of polyether with strong anti-foam ability and dimethyl silicone oil with strong hydrophobicity and rapid bubble breaking as the main components, and is matched with emulsifiers, stabilizers and other components that can make silicone oil and polyether organically combine.

Silicone defoamer use introduction

Silicone defoamer use introduction

Silicone is used as a spray-dyeing defoamer, which has been reported in many literatures. The old dyeing process, the general application of dimethyl polysiloxane defoamer, can achieve satisfactory defoamer effect, and ensure uniform dyeing. However, the new dyeing process uses high temperature and high pressure machinery. In this machinery, the dye is moved by the jet of the dye solution and is dyed at the same time.
