　　350gPolyurethane sealing bagHas expansion performance, in order to improve350g gas sealing adhesiveThe sealing effect and prevention of material flow or spraying from the hole opening should be quickly sealed by wrapping a retaining ring or wooden wedge with cotton yarn or cloth after delivery. After the material is completely cured in about 30 minutes, it can be directly connected to the gas extraction system for gas extraction.

　　Next, let's introduce350g polyurethane sealed bagSpecific usage method:

　　1. Due to the occasional occurrence of floating coal or even hole collapse in drilled holes, in order to ensure that the sealing tube can be smoothly inserted into the hole during sealing, the use of350g gas sealing adhesiveBefore sealing the hole, a sealing tube should be used to drill through the hole or an air duct should be used to blow out the floating coal inside the hole.

　　2. Use cotton yarn or transparent tape to tie the sealing bag onto the sealing tube according to the following requirements. A set of two bags of products are tied symmetrically horizontally about 0.5m away from the flower tube, and a cotton yarn is appropriately wrapped in front of a sealed bag to prevent the flow of Malisan material into the flower tube hole. The second group uses one bag, and the front end of the bag is tied at a distance of 0.5m-1m from the end of the first group. The third group uses one bag, and the front end of the bag is symmetrically tied to the second group at a distance of 0.5m-1m from the end of the first group. The sealing bags behind are tied symmetrically up and down in sequence.

　　3. After kneading and tying the bag, start from a sealed hole bag on the flower tube side, remove the divider strip on the sealed hole bag, and rub it up and down with appropriate force for 20-30 times with both hands. Rub for 15-25 seconds to fully mix the materials in the bag. Continuously proceed in sequence. The sum of the kneading time for all sealed bags should not exceed the time it takes for the sealed bags to burst.

　　4. Rub and feed the gas extraction pipe while feeding, and after each kneading is completed, another operator quickly sends the gas extraction pipe into the borehole. The sealing bag expands and bursts inside the borehole, and the material reacts in the space between the extraction pipe and the borehole wall, expanding and solidifying between the borehole walls to seal the borehole.

　　5. Due to the expansion property of the material, in order to improve the sealing effect and prevent the material from flowing or spraying out from the hole opening, it should be quickly wrapped with cotton yarn or cotton cloth to form a retaining ring or wooden wedge for sealing after the delivery is completed. After the material is completely cured in about 30 minutes, it can be directly connected to the gas extraction system for gas extraction.

　　At the same time, the company's technical team is developing various mining products. With excellent quality, competitive prices, and a cooperative attitude of "one word, nine tripods, one promise, gold", we have won an increasingly large market share.

　　350gPolyurethane sealing bagGood compressive performance; The consolidated body has good toughness and does not crack when compressed by 20-30%. It can fully adapt to the deformation of rock mass and coal seam. Once consolidated, it quickly strengthens the fractured matrix.

　　350gGas sealing adhesiveThe expansion rate is high, reaching 20-25 times the original volume, with small construction usage, low cost savings, and significant economic benefits. The transportation of equipment and raw materials is convenient, and can be delivered in one go without the need for specialized equipment or pipeline laying.
