Application scope and advantages of mining sealing materials
Application scope and advantages of mining sealing materials mining sealing materials are mainly used in underground coal mines. Its application scope is:
1. Control ventilation direction or strong temporary tightness;
2. Goaf and harmful gas are closed in coal cracks;
3. Fast sealing of fire zone firewall with flame retardant materials;
4. Other leakage, leakage crack, another closed upper and lower corner.
2、 Working principle of fast sealing material
Fast sealing, flame retarding and antistatic, the main principle of operation is to put liquid synthetic materials in two containers. When used, they are automatically proportionally mixed under pressure and catalyst, spray out with a spray gun, penetrate into the fissures at appropriate temperature, expand and expand in fissures, and form rigid foam compounds attached to the surface of the object, thereby playing a sealing role.
3、 Main advantages of mining sealing materials:
1. Light weight, easy to carry and transport, rapid closure of materials, small volume, packaging 11kg, packaging weight 18-20kg.
2. Easy to operate, without any power source or other technical auxiliary teaching facilities, one person can operate, open and use anytime, anywhere. Low labor relationship intensity and high efficiency.
3. Short time, fast closing speed and skilled operation can solve the problem of airtight closed wall in five minutes. The air leakage rate of airtight wall is very important to solve, especially in disaster relief, which can present the advantages of fast, short time and fast speed of airtight materials. Good sealing performance, spray at the target time is liquid state, can well penetrate into the target object, rising foam gap. The sprayer quickly closes over traditional sealing materials.
