Malisan is a kind of chemical raw material. When used, the raw materials and auxiliary materials are mixed, react and foam within a certain period of time, and form a hard solid after solidification. In recent years, Malisan has been widely used in coal seam plugging. Water, hole sealing, support repair, and other uses. What are the advantages of Malisan? 1. The tools used for Malisan construction are simple, and only a dual-liquid grouting pump and hole sealer are needed. 2. Malisan has low cost. Compared with other sealing materials, the price is reasonable, and the cost of use is equivalent to that of using cement. cost. 3. The strength of Malisan is very high. The solid material formed by Malisan is very hard through the process of reaction foaming and solidification. Malisan is a low-viscosity, two-component synthetic polymer polyimide gel material.
When this product uses high-pressure infusion to block water, when the resin and catalyst are mixed together and react or expand when encountering water, there will be a reaction of its own, or it will foam to form a multi-dimensional network dense elastomer. Characteristics. When the product is pushed under high pressure and injected into the coal rock layer or the location of concrete cracks, the cracks will be filled completely. To put it simply, the function of Malisan is to fill all the gaps and achieve the purpose of stopping leakage. From this we can see that Malisan is the product with the best performance among leak-stopping materials, especially water-blocking materials. Long service life and short construction period. Because Malisan has good pressure resistance and can withstand the movement of the formation, it has the characteristics of long life. At the same time, Malisan responds quickly, which greatly shortens the construction period, saves time, and does not affect production. , to ensure the safety production progress of coal mines. The construction equipment is simple and easy to operate. This product only requires a special pump and a mixing gun, and the construction process is simple and easy. Advanced hole sealing technology The hole sealing equipment and technology are the most advanced in the country. Only holes need to be drilled and the hole sealing operation is carried out under the action of special equipment. The raw material is injected into the hole sealer through the injection pipe. The hole sealer is expanded with a pressure of: (ratio of piston pressure to wind pressure) (diameter on the left and right). After the raw material is injected into the construction area, due to the hole sealer's impact on the drill A large pressure is applied around the hole, which closely combines with the surrounding rock and coal seams, effectively sealing the hole.
Secondly, the hole sealer can expand under the action of a minimum pressure of br force and can generate a pressure above br. The high-pressure thrust will extend the Malisan along the coal seam cracks until all cracks (including cracks that are difficult to detect with the naked eye and those in the coal seam) are cracks that reopen under the action of high pressure), thereby achieving the purpose of stopping leakage and sealing cracks. Mineral materials can penetrate into fine cracks very well. Although its viscosity is low, it can form a strong bonding force with the formation. It has good flexibility and can withstand subsequent formation movements. It reacts very quickly when it encounters water. It can react within ten seconds, thereby quickly sealing the water flow, and the foam formed after the reaction will not dissolve in water. It has very good pressure resistance, a very high expansion rate, and a small construction amount, saving money and effort. When this product uses high-pressure infusion to block water, when the resin and catalyst are mixed together and react or expand when encountering water, there will be a reaction of its own, or it will foam to form a multi-element network dense elastomer. When the product is pushed by high pressure and injected into the coal rock layer or concrete cracks, the cracks will be filled completely. To put it simply, the function of Malisan is to fill all the gaps and achieve the purpose of stopping leakage.
