Foamed silica gel is a two-component addition type silica gel. It is foamed after mixing to form a low-density silica gel similar to foam. It is soft and flame-retardant. It is a non-toxic, odorless, safe and hygienic environmentally friendly material.
Foamed silicone is a special polyurethane product filled with polyurethane prepolymer, foaming agent, catalyst and other ingredients in a pressure-resistant aerosol can. When the material is ejected from the aerosol can, the cured silicone foam has a variety of effects including caulking, bonding, sealing, thermal insulation and sound absorption.
The chemical structure of foamed silicone is stable, has a long service life, does not pollute the surrounding living environment, is self-extinguishing when away from an open flame, and only chars without dripping when burned. The size and shape design of the charring layer remain basically unchanged, and can be effectively used. It blocks the entry of air and prevents the spread of fire. The fire protection system has good safety performance. The performance of thermal insulation technology is even more excellent. The continuous and dense skin of foamed silicone and nearly 100% high-strength interconnected wall closed cells have ideal water impermeability.
We can take a polyurethane foam gun and clean it with detergent to ensure smooth flow of information. Then take a bottle of foaming agent, hold the middle of the can with your hands, shake it in the transverse direction of the can at least 20 times, and be sure to ensure that the prepolymer in the tank is fully mixed. Remove the protective leather sheath from the valve on the foaming agent thread ring, remove the cleaning agent from the foaming agent gun, thread the foaming agent tank to the interface of the foaming agent gun, and hold the blower tightly. Soak the handle of the gun, making sure the material container is on top. Hold the handle of the foaming gun tightly, ensure that the material tank is placed above the society, and the foaming gun is below the material tank. Open the flow control valve at the rear of the foaming gun. The appropriate flow rate can be adjusted through the flow adjustment valve behind the foaming gun.
After spraying, if you need to replenish water, you can immediately remove the air and follow the method of rehydrating the agent.
Hongtu foamed silicone is mainly used to make silicone foam sealing strips, silicone foam sheets, earthquake-resistant silicone foam boards, silicone foam rolls, copy machine transfer roller sponge tubes, printer shaft sponge tubes, silicone foam insulation Pipes, etc., the products made are mainly used as shock-absorbing and buffering accessories, and can also be used for filling bags and other products.
