Crystal Powder?


Crystal powder cementitious agent technology is a new cementitious material production technology which can integrate sulfate, nitrate and industrial solid waste independently developed by the medium crystal environment. It is a kind of cementitious material with high strength based on the molecular decomposition and combination of silicon, magnesium, iron, aluminium, sulfur and nitrate in specific proportion and reaction conditions.

Compared with other similar building materials on the market, the series of building materials with crystalline powder cementitious agent have a strong competitive advantage in cost and performance. The cost is 30% lower than that of cement products, and the compressive and flexural properties are 50% higher than those of cement products.

Medium-crystalline environment transforms harmful substances into beneficial substances through the production technology of crystal powder and cementitious agent and the production technology of building materials. Sulphur, nitrate and silicon-based cementitious materials form a high-strength, durable and stable hexagonal structure-honeycomb under pressure, which has high strength, low density, fire resistance up to A1 level, and also has the advantages of low thermal conductivity, good thermal insulation and low water absorption.

Crystal powder material can transform several sludge into new beneficial substances or change its location and application mode through simple chemical formula, so that by-products of flue gas treatment and various industrial solid wastes can radiate their new vitality. This is a new paradigm of environmental governance and a perfect integration of advanced technology concepts and advanced productive forces.

4. Mei Nei Board System

Curtain wall is a common external wall maintenance system in modern large-scale and high-rise buildings, and the building is safe for curtain wall fire protection. The requirements of energy saving and other functions are getting higher and higher. There are two problems to be noticed in the fire protection design of curtain wall buildings: one is the fire protection performance of curtain wall itself; the other is how to prevent the spread of fire in buildings as a building system. Because there are often gaps between vertical curtain wall and horizontal floor, once a fire occurs, smoke and flame will spread to the upper layer of the building through this gap. When the curtain wall material breaks down and falls behind, the flame will quickly move up to the upper layer from the outside of the curtain wall. After destroying the material of the upper curtain wall, it will run into the upper room. Therefore, if the gap is not treated or treated unreasonably, there will be a huge gap. Great fire hazards. As a kind of non-flammable A1 grade material, Zhongjing Mei Nest Board can solve the fire prevention problem for curtain wall. As a fireproofing and sealing component of curtain wall crevices, Zhongjing Mei Nest Board can organize the indoor fire in the lower floor of the building to spread to the upper floor. As an integral firewall body with curtain wall lining, Zhongjing Mei Nest Board is equivalent to adding a fireproofing wall behind the curtain wall. It can prevent the indoor fire in the lower floor of the building from spreading to the upper floor, and at the same time, it can also prevent the fire outside the curtain wall from spreading to the indoor, which The heat exchange between indoor and outdoor can provide a layer of "protective shirt" for fireproof, heat preservation and energy saving on the building ship.

Curtain wall fire lining:

Firewall should be set on the curtain wall lining board to prevent the indoor flame from destroying the outer curtain wall without any shelter in case of fire, and prevent the flame from outside to inside, and prevent smoke from the lower floor of the building to the upper room.

Fire blocking:

Fire prevention and blockade should be carried out between different floors to prevent the fire from spreading to the upper floors of the building and to prevent the flame and high temperature smoke from spreading inside the building.

Fireproof and thermal insulation partition wall

Effective organization of indoor and outdoor heat transfer, to prevent the spread of flame and high temperature smoke in the building interior.

5. Fire-proof duct system

Modern buildings have the characteristics of large scale, complex functions and centralized personnel, which bring convenience and quick experience to property users and modern fine science and technology, but also bring greater fire safety risks. A large number of fire cases prove that fire prevention ducts are conducive to fire control and increase rescue opportunities.
