Q:Who know what kind of fire shutter fire rating are there?: The fire resistance limit of high steel structure reduces the loss of fire, achieves remarkable results. The specification is mae in order to unify the application technical requirements of the design, construction method and quality standard of the steel structure fire retardant coating, and ensure the application effect, safety. The specifications is formulated in accordance with national engineering construction of the relevant policies and "giving priority to prevention, combining fire prevention and fire extinguishing. investigated characteristics of steel structure fire in China, summed up the experience of fire resistant coating for steel structure, and absorb domestic and foreign advanced technology and scientific achievement in fire retardant coatings for steel structures, and repeatedly solicited the relevant scientific research and design, production of construction, colleges and universities, public security department

Q:What are the specifications of fire resistant bag?: Mesh number, namely hole number, refers to the hold number in each square inch. 5o mesh refers to 50 holes in each square inch and 500 mesh 500 holes. The larger the mesh number is, the more the holes are. The larger the mesh number is, the smaller the hole aperture is. Generally speaking, mesh number× aperture (microns) = 15000. For example, the aperture of a sieve of 400 mesh is about 38 microns; the aperture of a sieve of 500 mesh is about 30 microns.

Q:How to understand qualitative and qualitative refractory materials?: Such as amorphous refractory castable, referred to as bulk loading, cast material, ramming material, refractory clay etc., utensils and other special products. Amorphous refractory material products, refractory heat insulating bricks and experimental and industrial crucible, spraying materials, such as burning bricks, electric melting brick, turn it into required shape and process heat treatment in where it is used.

Q:What's the classification of refractory material?: Magnesium aluminum is complex and mainly seeing what classification standard is like according to the appearance shape can be divided into two categories, setting and not setting according to the acid alkali can be divided into acidic, magnesia, high aluminum, ramming expected, spinel, spray coating, plastic, just the quality of the jade, daub material according to the chemical composition is divided into, such as clay, neutral and alkaline according to the operation mode can be divided into different castable, magnesium, calcium, magnesium chrome

Q:Which are fire proofing thermal insulation materials?: Fire proofing thermal insulation materials include: fire proofing heat insulating brick, fire proofing thermal baffle, fire proofing thermal insulation paper, fire proofing thermal insulation felt, fire proofing blocking, fire proofing fiber bulker, castable refractory, etc. In addition, there are also auxiliary products such as fire proofing cement gum, high temperature binder.

Q:What needs to be paid attention to in the construction of high- temperature refractory mortar?: In the construction of high-temperature refractory mortar, the following matters should be noted: 1. Take out the organic fire blocking material and knead it into tha shape of a ball. If the temperature is too low, the blocking material along with the package can be put into 40-70℃ warm water and heated before any other operation. 2. During the use of high-temperature daub masonry stove, the minimum mortar joint should be 0.5mm and general mortar joint should be 3-5mm, which can solve the processing and fine grinding of refractory brick on the brick grinder. Besides, it is conducive to the health of workers, and can reduce the masonry effort, ensure the quality and speed up the construction progress. 3. When making urgent repair on the stove, if the joint is much too large, 2-3mm refractory pieces can be appropriately added into the high- temperature refractory mortar, and stirred to fill the joint so as to shorten the repair time and ensure normal production. 4. High- temperature refractory mortar can be painted inside various furnace body, and it should be guaranteed that the surface of the furnace body has no dust or debris before painting. The holes should be cleaned up before plugging. Lay, embed, and fill the blocking material into the gap of holes evenly. For larger holes, flame screen can be used as the framework to increase strength.

Q:what is the specs of thermal insulation refractory slab ?: it is produced in accordance with scientific formula by using asbestos, glass fiber and potclay . it has strong tension strength capable of withstanding 1400 degrees Celsius, specifications!: 1.5DD20 (mm)

Q:Who knows about the grade C fireproof door materials?: I am happy to answer your questions. Wood or steel materials are usually used. The new national standard fire doors: According to the enacted GB12955-2008, the fire endurance of grade C fire doors is 0.5 hours and that of grade A and B are 1.5 hours and 1.0 hours respectively. I hope my answer can help you.

Q:How many hours of the fire endurance time of the rock wool laminboard?: Hello. The fire endurance now on the market is generally about two hours. The 50mm color steel sandwich version of Bo magnesium rock wool, with refractory time being five or six hours, is very good.
