Q:Can the teflon material resist fire?
Teflon material does not burn, but the heat resistance temperature of it is about 300℃.
Q:What are the raw materials of refractory?
Of course, different types have different raw materials: Magnesite (the electric smelting: alkaline refractory, magnesia-carbon bricks, alkaline, high-purity) + crystalline flake graphite + phenolic resin + additive (silicon powder, aluminite powder, silicon carbide powder, or high-temperature asphalt,etc.) , acidic refractory: The neutral is not easy to answer. such as. You can check out the classification, such as
Q:How to deiron refractory?
Our company uses magnetic separation method.
Q:Can someone professionally introduce the classifications of refractories?
Whatare the classifications of the refractory index levels? There are three categories of refractory index levels. Anyone familiar with the industry may already know that if you're new to the refractory and don't know much about it, the following information may be helpful to you. Refractory index level can be devided into three general categories of special refractories, advanced refractories and ordinary refractories. The first category, special refractories. Whose refractoriness is higher than 2000 ℃, spinel brick, pure oxide products, high purity directly bonded magnesia-chrome brick, cast products, non-oxide products belong to this grade. The second category, advanced refractories. Whose refractoriness is from 1770 to 2000 Celsius degrees, mullite bricks, high alumina brick, magnesia-alumina brick, ordinary magnesia products, olivine bricks, ordinary magnesia-chrome brick belong to this grade. The third category, ordinary refractories. Whose refractoriness is between 1580 and 1770 Celsius degrees, equivalent to Al2O315% ~ 45% refractory products in the binary system of SiO2-Al2O3. Kaolinite is the main mineral of raw materials.
Q:How to determine the fire resistance rating of the aluminium-plastic panel?
The fire resistance rating of the aluminium-plastic panel is determined by two indicators, namely national compulsory standard of GB8624 "Building Materials Combustion Performance Grading Method ", and GB/T17748 "Aluminium-plastic Composite Panel National Standard" . Classifications of combustion performance of building materials in our country are as follows: A class: Incombustible building materials; B1 class: Flame-retardant building materials; B2 class: combustible building material; B3 class: flammable building materials. The fire resistance rating of the aluminium-plastic composite panel shuld be no less than B1 class. 1. Detection indexes and requirements of fireproof aluminum-plastic composite panel (B1 class): (1) Conduct the test according to GB/T8625-88, the average leftover length of each test specimen should be more than 150mm, (any test piece should have leftover length), and the maximum average flue gas temperature of each test should be no more than 200 ℃; (2) Conduct the test according to GB/T8626-88, flame hight indicators.
Q:What refractories are resistant to fluorine gas?
It is recommended to use fused-quartz brick, which will produce hydrofluoric acid fluorine (an acidic gas) when water vapors. It is cheap. While it is recommended to use silica brick if it exceeds 1,200 degrees. So acidic refractory is an advisable refractory for using. It works well if the temperature is below 1200 degrees.
Q:What is the importance of silicon powder in refractory processing?
it depends on the type of refractory material, in addition to lS friends talked about, in the amorphous mobility\ strength should also have an impact
Q:How to divided the grade of external wall thermal insulation materials?
Synthesized the three versions of GB8624 (1997,2006,2011), external wall thermal insulation fire rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. There are many technical indicators to make specific division, but I partly cannot report for a while, because it is very professional and technical. Please contact Qingdao Shanfang Instrument Co., LTD for details, they specialized in the external wall thermal insulation materials fire rating test
Q:What are the meanings of azs, 34% and ec in fused brick?
The fused brick, also called zircon corundum brick, is shorted as AZS for three chemical components in Al2O3-ZrO2-SiO2 ternary diagram. I don't know the meaning of EC.
Q:What is the role of the vermiculite fireproof material?
It can be widely used in construction, decorative ceiling, wall, floor and fireproof door . Especially suitable for airport, railway station, passenger terminal, exhibition hall, hotels, shopping malls, hotels, and other public places and factory, fuel warehouses which have high requirements for fire proofing, etc. With its special thermal insulation, it can also be made to the various types of heat insulation board offered to machines (such as a variety of industrial furnace and assembly line equipment) and furniture, etc. Due to the low density of the product itself, a lot of shipyards in foreign countries use it as ceiling, wall and deck, so the development potential of the domestic shipbuilding market is huge.Expanded vermiculite is porous, lightweight, and dystectic, the most suitable for insulating materials at high temperature (below 1000℃) and fire insulation materials. In the experiment, 15cm- thick cement vermiculite burns for 4-5 hours under 1000℃, but the back temperature is only 40℃. 7 cm-thick vermiculite slate burns for 5mins through the fire flame welding net under 3000℃, the frontage melted, but you don’t feel hot with your hands holding the back side. According to aforementioned, vermiculite slate is superior than all insulating material, such as asbestos, and diatomite products.
We has been adhering to scientific and technological innovation as the company development ideas, establishing the export-oriented development strategy and has close technical cooperation with scientific research institutions.We supply many kinds of calcined bauxite.
