Mining seal materials are mainly used in coal mines, its scope of application:
1, control the direction of ventilation or temporary tight tight;
2. Goaf and harmful gas are closed in coal cracks;
3, the fire area firewall is quickly sealed with flame-retardant materials;
4, other leaks, leak cracks, another closed upper and lower corners.
Second, the basic principle of rapid sealing materials
The main working principle is: the liquid synthetic material is placed in two containers, when used, under the action of pressure and catalyst, automatically mixed in proportion, sprayed with a spray gun, at the appropriate temperature, quickly penetrated into the cracks, and expanded foam in the cracks to form a rigid foam compound attached to the surface of the object, so as to play a sealing role.
Three, the main advantages of mining sealing materials
1, light weight, easy to carry and transport, the material quickly closed volume is small, packaging 11KG, packaging weight 18-20KG.
2, easy to operate, without any power source or other technical assistance teaching facilities, one person can be operated, anytime and anywhere. The intensity of labor relations is low and the efficiency is high.
3, short time, fast closure, skilled operation, can solve the problem of airtight closed wall in five minutes. The air leakage rate of the closed wall is very important to solve, especially in disaster relief, which can present the advantages of fast and short airtight materials and fast speed. Good sealing performance, spray at the target moment is liquid state, able to penetrate well into the target object, rising foam gap. Sprayer closes quickly over conventional sealing materials.
