- Q:who knows the technology of fireproofing material?
- 1, dealing mould, scrape and clean the thick liquid on the surface of mould with tin-coated steel scraper blade or plaster tool. 2, adjust laminator, according to the thickness of fireproof?panel, adjust each roller, keep them parallel. 3, ingredient, according to the requirements of recipe, stir the raw materials uniform with agitator. (usually we should add bittern firstly, stir it with modifying agent for 5 minutes, then add filler and stir for 2-3 minutes, finally add grogs and stir it to uniform) note: the stirring speed should be kept in 60-80 r/min. 4, place the cloth, place a layer of non-woven fabric and two layers of glass fiber fabric (mechanical spread fabric). 5, flitch, place the materials after compounding and stirring into stop gauge of laminator, then you can start up and produce continuously, it's finished product after finishing. note: the distance between two templates is 2-4mm.
- Q:What are the applications of refractory busway?
- Fire-resistant busway has excellent insulation property, and it can not only be used continuously in a normal environment, but also be used continuously when catching fire for more than one hour. It can be used in high buildings and important facilities in replace of fire-resistant cables to transmit and distribute electricity.
- Q:what's the requirements of refractory for forge furnace?
- . . . . . . . .
- Q:How many types of fire-resistant material?
- 1. Acid fire-resistant material refers to one with more than 93% SiO2. It is featured by resistance to the corrosion of acidic slag ad high temperature and easy to react with alkaline molten slag. 2. Alkaline refractory material generally refers to one with magnesium oxide or magnesium oxide and calcium oxide as the main component. It has high refractoriness and strong resistance to basic slag. 3. Silicate aluminum refractory material refers to one with SiO2, Al2O3 as the main component. According to the content of Al2O, it can be divided into three categories: half siliceous (15-30% Al2O3), clay (Al2O3 30 ~ 48%), high aluminum (more than 48% of Al2O3). 4. Fused cast refractory material refers to shaped refractory products made by high temperature melting and casting.
- Q:How long is the fire-resistant time of fireproof wooden door?
- Wooden thermal insulation fireproof door using flame-retardant timber or flame-retardant timber products to make door frames, skeletons of door leaf, door panels. If the door leaf need to be filled with materials, the filling materials should be fireproof thermal insulation materials which is non-toxic and harmless to human body, and matched fireproof door composed of fireproof hardware. Use doors without age limits.
- Q:Who knows how to divide the building fire grade and fire resistance grade?
- I hope to help you building fireproof rank division is one of the most basic measure in building fire safety technical measures, Building's fireproof rank is divided into class one, two, three, four according to China's architectural design specification. Fire-resistant capability of the highest level is the strongest; Fire resistance of four level of the weakest. The fire resistance level of a building depends on the combustion performance and fire resistance of the building components that comprise the building. The so-called building component refers to a series of basic components, such as wall, foundation, beam, column, floor, stair, ceiling and so on. The judgment condition of the fire resistance There are three conditions for components' fire resistance limit to be reached, namely, the fire resistance limit of the building component: Loss of support and integrity; loss of time to fire the role of the time; as long as any of these three conditions is met, it will reach its limit of fire. Hope my answer will help you.
- Q:Who knows how many fire heat preservation material are there?
- Fire proof board is a fire refractory building material for surface decoration, widely used in interior decoration, furniture, kitchen cabinets, laboratories mesa, walls and other fields. Fire board is base paper (titanium powder paper, kraft paper) processed by melamine and phenolic resin, high temperature and high pressure. 1 mineral wool board, glass wool board: mineral wool, glass wool insulation. It does not burn itself, have good performance such as high temperature resistance, light quality. Such plate have evolved into plate with inorganic adhesive material as base material, mineral wool, glass wool as reinforcing material plate. 2 cement board: High strength, wide source. In the past, it is used to make fire prevention ceiling and partition wall, but its fire resistance is poor. Cement concrete component has good heat insulation and sound insulation performance. It can be used as the partition wall and the roof panel.
- Q:How long is the fire resistance time of the AAAfire resistance rolling shutter door?
- How long is the fire resistance time of the AAA fire resistance rolling shutter door?
- Q:which kind of material is chosen for fireproofing window?
- Firstly, fireproofing window glass must be tempered, ordinary glass won't play a role of fireproofing, and fireproofing window fan is fixed, can't be open, if you can open it, it won't play a role of fireproofing. And you can ask the property to provide texture report of fireproofing windows, fireproof material stipulated by our national fire protection laws and regulations must have fireproofing inspection reports, there must be. and fire window glass should have a fireproofing sign. The main role of fireproofing window is to isolate the fire, and play a role of fireproofing and escaping, avoid the fire quickly spread in.
- Q:which kind of material should be used in fireproofing cabinet?
- Here are a few good materials: 1. The mineral wool board, glass wool board: it mainly tales mineral wool, glass wool as insulation materials. It's non-combustible, light weight and has good high temperature resistance, but there are shortcomings ① short?fiber will harm the human respiratory system, ② poor sheet strength, ③ poor barrier property of sheet for smoke of fire disaster, ④ poor decorative properity, ⑤large installment and construction work. Thus, most of the boards were sheets that take inorganic anchoring material as base material, glass wool as reinforcing material. 2. cement board: Cement board has high strength and wide sources. It is often used in fireproof suspended?ceiling and partition in the past, but it has poor fire resistance and is easy to burst and lose protective function , which will limit it's applications. Cement concrete component has good thermal insulation and sound insulation properties, and it can be used as partition and roof board. Fiber reinforced cement board and other improved varieties appear in the construction?materials market, and they are high strength and have good fire resistance, but their disadvantages are poor toughness, large alkalinity and poor decoration effect. 3. perlite board, cenosphere board, vermiculite board: It's a kind of hollow plate that takes low alkalinity cement as base material, perlite, glass beads, vermiculite as the aerated filling material, and is made by adding some auxiliary. It has characteristics of light weight, high strength, good toughness, fireproofing and thermal insulation, easy for construction,etc. and it can be widely used in high-rise building frame compartment, household, bathroom, kitchen, communication pipe and other non-load bearing areas.
