250g gas sealed bag, Malisan sealed bag, high hardness polyurethane sealed bag manufacturer

Description :

　　250g gas sealed bag, Malisan sealed bag, high hardness polyurethane sealed bag manufacturer

　　Process simplification and improvement in grouting and sealing agent technology410g mining sealing bagAdopting a connected bag structure, the polymer chemical material Malisan two-component is prefabricated and packaged in bags. The materials react and mix during on-site use, relying on Malisan's excellent bonding, expansion, and sealing properties to achieve rapid sealing of gas extraction boreholes.410g mining sealing bagRelying on the expansion pressure of material reaction to achieve pressurized sealing of holes, increasing the sealing effect and improving the negative pressure of pumping.
