Q:What are the differences between first-level fire-resistant materials and second-level fire-resistant materials?
The combustion performance of materials could be divided into: A( noninflammability), B1(flame retardancy), B2(flammability), B3(inflammability). Building materials are divided into four ranks according to these properties. 1. In accordance with Code for Design of Building Fire Protection(GBJ16-1987)(revised edition in 2001), fire hazards in producing and storage can be divided into five types. In Fire Prevention Code of Petrol Chemical Enterprise Design(GB50160--1992)(revised edition in 1999), classification of fire hazards is also achieved according to the hazards of materials that have been using, producing and storing. Measures in prevention of fire explosion could be taken from the perspectives of fire separation, fire resistance level of structures, allowable floors, safe evacuation, and fire extinguishing facilities based on different levels of fire hazards. 2. Four fire resistance rating of buildings are listed in the book Code for Design of Building Fire Protection. And specific stipulations are made to the fire resistance of main elements of buildings, such as bearing walls, beams,pillars, and floors. When designing a building, if permitted, refractory materials of high-rank should be adopted in those buildings which have high potential fire hazard and a lot of combustible material and valuable equipment. While making sure fire resistance rating, the duration of fire resistance of each elements should meet its requirements.
Q:What is the material composition of the new fire-resistant coating?
New fire retardant coating materials are produced by non-toxic expanding materials and special process, with no pollution. Use natural bite when installing, without using the formaldehyde and other toxic glue. It consists of a variety of organic matters, so it adapts to the natural environment, with long time of fire-resistant; The fire-resistant time for new fire retardant module is up to 4 hours or more, three hours more than the standard prescribed by the state. It is composed by the specially formulated materials, with no flying smoke, good heat insulation effect, fast heat dissipation, scientific and rational design, easy using and no falling off and long period of effective.
Q:What thickness is needed of the ultra-thin fireproof paint with a fireproof time of 2.5 hours?
Fireproof of steel components can adopt outsourcing concrete (or laying bricks method), fireproof coatings, fire prevention board coated and composite structure. Anti-firing plate can be divided into the fire protection lamella thickness plate and thin plate. Fire protection lamella thickness plate is of 20 ~ 50 mm. There are mainly calcium silicate and decayed stone of fire prevention board fire board, main varieties KB board, CF board; Fire sheet thickness is between 6 to 15 mm and the main varieties have short fiber reinforced cement pressure plate, fiber reinforced ordinary calcium silicate board and glass cloth reinforced inorganic plate. I hope you can be satisfied.
Q:How many kilns using refractories are needed? What are the furnaces respectively?
There are many magnesia-chrome bricks and alkali insulation tiles); aluminum manufacturer roaster; The bottom of the glassworks regenerative chamber generally use the clay checker bricks, which is popularly used in many places of the steel mill. the upper of the power plant uses low pore brick and magnesia bricks. The forehearth uses the corundum bricks, and the cement plant uses dry and wet rotary kiln (silmo brick
Q:How long is the duration of fire resistance that fireproof door of level B can endure?
According to the duration of fire resistance, fireproof doors can be divided into three levels, namely level A,B,C. And accordingly, the duration of fire resistance of them should not lower than 1.20h, 0.90h and 0.60h. Fireproof door, a door that can meet the requirements of fire resistance stability, fireproof door integrity and thermal insulation at a certain time, is a fireproof separator which is located in fireproof partition, emergency staircase and vertical silo. Apart from functioning as a common door, a fireproof can also prevent the spread of fire and smoke in a certain period to make sure that people are safely evacuated.
Q:What are included in wall fireproofing material?
Wall fireproofing materials include dry wall and gypsum block. Dry wall is made into board material through process by using building plaster as main material, adding an appropriate amount of additive and fiber to make board core and using tailor-made board paper as protection surface. Dry wall ia characterized by light weight, sound insulation, heat insulation, strong processing performance and easy construction method. Gupsum block is lightweight building plaster product made by using building plaster as main raw material, adding water, stirring, moulding by casting and drying. Fiber reinforced material or lightweight aggregate are allowed to add during the production and foaming agent can also be added.

It is a kind of new wall material with low carbon, environmental protection, health and in line with the development requirements of the times.
Q:What is the material of fire resistant glass reinforced plastics grating?
What is the material of fire resistant glass reinforced plastics grating?
Q:Is the ball mill used in production of refractories?
Refractory is a kind of non-metallic material that is of resistance to thermal shock and chemical erosion, low thermal conductivity and low expansion coefficient. The refractoriness of the refractory is not less than 1580℃. The usage of the refractory is broad. Refractory materials include refractory bricks and powders. Abandoned refractory bricks can be recreated as new bricks after they are crushed by a crusher and grinded by a ball mill. The ball mill and crusher are needed to grind and crush the material in the production of the refractory. The ball mill produced by Zhengzhou Xinhai Machinery Manufacturing Co. has excellent performance and there are many successful cases in Inner Mongolia, Heilongjiang and Guangdong. At the request of the national environmental policy, the company adjusts the equipment details, allowing the equipment to ensure the volume of production while reduce energy consumption.
Q:What are the electrical fire protection materials?
Electrical fire protection materials are the following: 1, fire proof board It is the most commonly used materials in the market, which has the advantages of fire prevention, moisture, abrasion, oil, easiness to clean, and more varieties of colors. Installed in the building exit corridors, stairs and corridors, such as fire ceiling ceiling, it can ensure that people can be evacuated safely, and to protect people from the spread of the fire. 2, fire proof door, fire proof door is divided into wooden fire door, steel fire door and stainless steel fire door. Fire proof doors are usually used for the opening of the firewall, the entrance of the staircase, the evacuation of the aisle, the openings and other parts of the pipeline, the fire prevention, playing an important role in reducing the loss of fire. 3, fire shutter It can be set in the location where it is not convient to install a fire proof wall, fire shutter generally has functions such as good fire resistance, heat insulation, smoke, compression, anti aging, wear and corrosion. 4, fireproof and mothproof wood fire wood moth is made by putting ordinary wood into the solution containing calcium and aluminum, and then into the solution containing phosphate and silicate. In this way, two ion will be undergong chemical reaction in the wood, forming materials similar to the ceramic, and filling the gap of cells and tissues, so that allowing it to have fireproof and mothproof performance.
Q:Can anyone tell me what is a high alumina refractory?
Refractories refer to a class of inorganic non-metallic materials whose refractoriness are no less than 1580 ℃. Refractoriness is the Celsius temperature when cone-shaped samples can resist high temperature without softening and melting down in the absence of a load. But it is not accurate to define refractory merely by judging that whether the refractoriness is no less than 1580 ℃. Currently, the materials whose physical and chemical properties allow them to be used in high temperature environments are called refractories. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, power and so on, among which the metallurgical industry is the largest demander in this regard, accounting for 50% to 60% of total output. Hope it will help you out!
