Mine sealing filling material

Product Overview This airtight filling material is produced and developed by Hebei Xingtai Maosen Foam Plastic Co., Ltd. This material was developed to improve the construction speed of underground coal mine sealing and cavity filling and increase production efficiency. It is a block foam body that is preformed by reacting a variety of polymer compounds with an appropriate amount of cross-linking agent, stabilizer and curing agent under specific conditions. The foam is light in weight and has good sealing performance. It is produced by a two-component reaction and has good gas barrier and foaming properties. It is widely used in temporary (permanent) sealing of coal mines and tunnels, filling of coal caves and coal seam fissures, construction of firewalls, blocking of toxic and harmful gases and Roof support and other areas. It is especially suitable for filling coal caves, various fissures and air leakage channels in high-risk areas, and sealing up and down the working surface to prevent air leakage and gas outflow in goaf areas. The product does not burn or support combustion. It has outstanding explosion-proof and anti-static properties and has a good effect on gas sealing and fire prevention. After the material is formed, its performance is stable, durable, and does not break.
Reaction Principle
The two-component is divided into base material and catalyst and mixed at a volume ratio of: or: to instantly foam and expand rapidly, and the expansion multiple can reach times of the initial volume. Expanding foam solidifies and hardens within minutes.
Product usage
. Can be used for temporary sealing in rapid construction
. Blocking the working surface to prevent gas from gushing out in the goaf area
. Filling the hollow.
Product material features
. The material is light in weight and easy to transport, which can greatly reduce the labor intensity of workers when closed during construction
. When used, it can be cut into units of different sizes and shapes according to construction requirements
/> .The construction speed is fast and the tunnel can be sealed in minutes
.The product is flame retardant and explosion-proof, airtight and airtight, and when there is pressure on the roof, the more pressure the better the sealing performance
.The product has a certain plasticity and can maintain the tunnel after construction It is dense and airtight
. There is no need to purchase special equipment and the product can be reused to save costs
. Users can customize products of different strengths and sizes according to different locations and requirements
. The product is an environmentally friendly product that is non-toxic, odorless and pollution-free during use.
How to use the product
. Rapid construction of temporary airtight walls: Determine the approximate number of cubic meters of airtight material required based on the cross-sectional size of the construction tunnel, and then cut it into appropriate units according to the construction conditions and requirements
. Fill with coal Yankong Cave: According to the volume of the cave, select stronger material blocks, intercept blocks of appropriate size and press them into the cave, which can play a good role in supporting and filling.
Product Precautions
. Do not press heavily during transportation to avoid damaging the product
. During construction, use the entire product as much as possible according to the size of the sealed section to reduce the number of cuts to avoid waste.
