b.After that, the glue is applied, the hose is unscrewed, the plastic nozzle is installed, and then the required size is opened with a blade, so that it is easy to squeeze the glue to the required position;

c.After use, the next step is to wait for curing, then put the coated part in a stable position and wait for curing. The curing is from the outside to the inside, the depth of glue curing is 2-4mm, that needs to be cured within 24 hours, the humidity will be 55% will be cured, if the depth exceeds this depth, the time will be extended, if the humidity is relatively low, the curing time will be extended.

What kind of profile is the silicone rubber sheet.

Silicone rubber sheet is actually made of silicone rubber, and silicone rubber can be divided into two categories: organic silicone and inorganic silicone. Inorganic silica gel is a highly active adsorption material, which is made by reacting with sodium silicate and sulfuric acid, and finally made after a series of treatments such as aging and acid foaming.

Silica gel is also an amorphous substance, the chemical formula is that it is insoluble in water and other solvents, non-toxic and tasteless, and will not react with any substance other than strong alkali and hydrofluoric acid. It is also widely used, can be used as a special material in aviation, cutting-edge technology, military technology departments, and can also be used in construction, electronic and electrical, textile, automobile, machinery, leather and paper, chemical light industry, metal and paint, medicine and medical treatment.

Features: It has good insulation performance, aging resistance, sealing performance, good adhesion and high strength, and is a non-corrosive one-component room temperature vulcanized silicone rubber; Uses: The main uses of silicone rubber are insulation, moisture-proof, sealing, bonding, vibration-proof, etc

Silicone rubber has good insulation performance, aging resistance, sealing, good adhesive performance, and will not have any problems when used for a long time. It can be used for insulation, moisture-proof, sealing, shockproof, etc. It can also be used for sealing aircraft cockpit seats, aura, machine manufacturing and other related conditions.

It is characterized by heat resistance, cold resistance, weather resistance, electrical properties, electrical and thermal conductivity, radiation, flame retardancy, and air permeability. Widely used in aviation, cable, automotive, electronics, electrical appliances and other industries.

Heat resistance: Silicone rubber has much better heat resistance than ordinary rubber, and can be used almost forever at 150 degrees without performance change; 10,000 hours of continuous use at 200 degrees; It can also be used for a period of time at 350 degrees. Cold Hardiness:

Weather Resistance Electrical Properties Electrical Conductivity Thermal Conductivity The properties of silica gel vary depending on the fillers and additives added. It is mainly manifested in: physical properties (hardness, tensile strength, elongation, tear strength, shrinkage, plasticity, specific gravity), electrical properties, chemical stability (temperature resistance, weather resistance, acid and alkali corrosion resistance) and other aspects.

Longer service life in harsh environments, unaffected by weather for a long time – rain, snow, moisture, ozone, solar ultraviolet (UV) rays; When exposed to harsh environmental stresses, its inherently good electrical insulation quality does not change significantly.

Extended operating temperature range—from -100°C to 316°C (-148°C to 600°F); It retains its natural flexibility and elasticity over a wide temperature range (compression set resistance) to improve the comfort and feel of consumer products. In addition, it also has the characteristics of good sealing performance, inertness (tasteless, odorless) and so on.

Due to the characteristics of silicone rubber, it is used in hot water bottle seals, pressure cooker rings, heat-resistant handles, low-temperature sealing rings, sealing materials for outdoor use, high-voltage insulators, high-voltage caps for televisions, electrical parts, heat sinks, thermally conductive gaskets, thermal conductive rollers for copiers and fax machines, electrically insulated cables, connectors for nuclear power plants, and various fire-resistant fields. Ketaili silicone products custom factory, according to the custom needs to design and produce silicone earphone covers, silicone watch bands, silicone gifts, silicone pads, etc.

Silicone rubber classification 1, according to the degree of polymerization classification liquid silicone rubber: is a kind of organic silicone rubber relative to the mixed semi-solid silicone rubber and common room temperature vulcanized one-component silica gel, this kind of rubber has good fluidity, fast vulcanization, can be poured and molded, can be injection molding. Compounded silicone rubber:

It is a synthetic rubber made by adding silicone rubber raw rubber to a double-roller rubber mixer or a closed kneading machine and gradually adding silica, silicone oil and other additives to it repeatedly. 2. According to the vulcanization temperature classification of room temperature vulcanized silicone rubber: it is a two-component condensed room temperature vulcanized silica gel, its raw rubber is usually hydroxyl terminated polysiloxane, and then combined with other compounding agents and catalysts to form a rubber compound, the viscosity of this rubber material can range from 100 centime to 1 million centi.

High-temperature vulcanized silicone rubber: It is a linear dimethicone based polymer with high molar mass, mixed with reinforcing fillers and vulcanizing agents, etc., vulcanized into elastomers under heating and pressure 3, classified by packaging form One-component room temperature vulcanized silicone rubber: although it is easy to use, because its vulcanization is dependent on moisture in the atmosphere, the thickness of the vulcanized magnetic needle is limited, and it can only be used in occasions that require a thickness of less than 6 mm.

Two-component room temperature vulcanized silicone rubber: It is the most common room temperature vulcanized silicone rubber, and its raw rubber is usually hydroxyl terminated polysiloxane, and then combined with other compounding agents and catalysts to form a rubber compound, the viscosity of this rubber material can range from 100 centime to 1 million centi.

Silicone rubber (English name: Silicone rubber) is divided into hot vulcanization type (high temperature vulcanized silica rubber HTV) and room temperature vulcanization type (RTV), of which the room temperature vulcanization type is divided into polycondensation reaction type and addition reaction type. High-temperature silicone rubber is mainly used to manufacture various silicone rubber products, while room temperature silicone rubber is mainly used as adhesives, potting materials or molds.

The hot vulcanized type has the largest dosage, and the hot vulcanized type is divided into methyl silicone rubber (MQ), methyl vinyl silicone rubber (VMQ, the most dosage and product grade), methyl vinyl phenyl silicone rubber PVMQ (low temperature resistance, radiation resistance), and other eye silicone rubber, fluorine silicone rubber, etc.

Commonly used are: 1. Dimethyl silicone rubber; 2. Methyl vinyl silicone rubber; 3. Methyl phenylvinyl silicone rubber; 4. Fluorosilicone, nitrile silicone rubber; 5. Benzene and phenyl ether silicone rubber.
