Q:Which one is better, fire-resistant wood or steel?
From the aspect of low-carbon and environment protection, the steel and timber structures are both OK, they are both renewable resources, the steel can be recycled and melt down again and wood can continue to be planted. Fireproof board Fireproof board is a refractory material used for surface decoration. It is widely used in interior decoration, furniture, kitchen cabinets, laboratory tables, walls, and other fields.
Q:What are the technical requirements for refractories?
How high the temperature is and what is this refractory?
Q:What's the poured refractory material?
According to the volume density, it can be classified as follows: Heavy (>2.0g /cm3), medium heavy (1.0-2.0g/cm3), light (0.4-1.0g/cm3); classified by binding agent: hydraulic bond, chemical bond, coagulation binder, hydraulic and coagulation binder; classified by material: material of clayey, high alumina, silicious, magnesian, alumina-magnesia, magnesian-chrome, magnesia-zirconia, silicon carbide-based, etc.
Q:what's the application of fireproofing abs materials?
a kind of ABS alloy shell, a toy of child, low load bearing, refrigerator lining, it can be processed into various wear-resisting sheets, plates,and has good electrical performance, it can be used as electronic components or auto parts, all kinds of insulation materials, it's easy to machining on the surface, so it can be made into designated special products (such as electroplate), and easy coloring, it can be processed into colorful products, also can be used as a fireproofing electrical appliance outer covering, adding alloy to it will improve its comprehensive performance, etc
Q:Which plant need to make refractory mould?
Q:Does anyone know about the A-level fireproof materials?
A-level decorative integrated plates of thermal insulation, water- and fire-proofing mainly can prevent fire and insulate heat with A-level fireproofing glass fiber as thermal insulation materials. The classification of A1-level external wall materials of thermal insulation, fire- and water-proofing: First, external wall thermal insulation materials: 1. silicate thermal insulation materials 2. gelatine powder polyphenyl granules 3. steel wire gauze picking cement cystosepiment (grs board) 4. extruded sheets; Second, roofing materials: 1. xps extruded sheet 2. EPS foam board 3. perlite and perlite brick 4, vermiculite and vermiculite bricks; Third, heating and air conditioning materials: Polyurethane, rubberplastic sponge, polyethylene, polystyrene foam, glass wool, rock wool; Four, steel structure materials: Polystyrene, extruded sheet, Polyurethane board, glass wool roll mat, etc.
Q:What types does soft fire prevention materials have?
1. In new fire retardant coatings, expanded vermiculite, expanded perlite heat insulation material and cenosphere adiabatic powder are an integral part of thick film type fire-retardant coating. They are also the main factors influencing the fire fire retardant coating performance level. And fireproof heat insulation performance of fire retardant coating is based largely on the back fire coating surface temperature factors, and also related to the fire resistance. If the time of reaching the same temperature is longer, it means its insulating fire stays is better, so the fire resistance is higher. 2. The new type of fire prevention board. Now new type of fire prevention board are welcomed by the people is mostly due to its environmentally friendly. And with an increasing number of high-rise building, the fire and strength requirements are constantly improved. It is a big test for plate performance and the standard. Now fire prevention board mainly adopts siliceous materials or calcareous materials, and then stick with the fiber material, light aggregate, binder and the mixture of chemical additives. In this way, it can not only act as fire prevention, but also can improve the thermal insulation performance, and with light quality, good bearing capacity, good durability, no aging problem. More importantly, it is environmental protection. 3. The new flame retardant materials. New flame retardant material currently focus on in polymer composite material, which performance is good with very good high temperature resistance and heat resistance, therefore it's not easy to deform after the fire. At high temperature, it also can use for a long time, so as to ensure the safety.
Q:What types of steel are silicious quicksand and chromium quicksand used in respectively?
Chromium quicksand can be used in steel-making process that has longer refining time like LF, VD and RH, in stainless steel drainage and thin plate drainage agent. Silicious quicksand is used in short steel-making process, process that is less than 45 seconds or process without refining. You can consult Hua Heng for details or inspect it by yourself.
Q:What level is the rock wool board fireproofing material ?
The fire rating classification is a provision for all insulation materials, rather than to separately divide rock wool. Determine the value of the material fire rating according to the relevant test items of 8624. As the rock wool is made from basalt fusion, so it is the level A non-combustible material. And those we usually see are the mineral cotton and glass wool, with its refractory temperature lower than the rock wool's. Rock wool board is now mainly used in wall insulation, which is a level A fire insulation material.
Q:What material is used to make furnace pipe of refractory bricks?
Furnace pipe of refractory brick is an indispensable part of casting cupola. Furnace pipe is divided into upper and lower part. Radial direction and axial breathing. The upper furnace pipe adopts double layer steel structure and countercurrent air supply mode. The lower furnace pipe is made by processing integrated heat resistant steel in flange, fin and inner wall in wearing parts. The operation life is over 3000h. There is radiating rib of heating air on the edge of furnace pipe liner by using the heat of casting cupola to heat air in cupola. Hot air temperature is about 180-250℃, which contributes to improve trhe thermal efficiency of production equipment, decrease production cost and improve economic benefit of enterprises.
