Q:Who knows how many kinds of fireproof insulation materials are there in the market?

Portland cement, insulation stone, calcium powder and platycodon grandiflorum are the main raw materials of inorganic active insulation materials. Advanced manufacturing techniques and chemical Technologies have been used to conduct many tests, thus the close-celled inorganic active insulation materials are successfully developed. Products have advantages of fire-resistance, small deformation coefficient, aging-resistance, stable performance, environmentally-friendly, and good compatibility with rendering coating and subtractive wall, security, stability, and also have a life as long as the building itself. Good fireproofness: The materials of fireproof insulation board are inorganic (cement) which has A1-level fire-resistance, are non-combustible materials, and good at resisting fire. I hope my answer can help you.

Q:what is the requirements of roofing insulation materials fire rating?

The fireproofing requirements of architectural design are regulated by architectural design fire?safety?rules, roofing insulation material only has the requirements of materials combustion performance, namely non-combustible material. No fire rating requirements.

Q:How to choose construction external wall thermal insulation and fireproofing materials?

Now external wall insulation decoration one board is more popular thermal insulation material. Low-carbon energy-saving insulation decoration board combine two constructions (decoration, insulation) into one, saving nearly ten processes,and construction period. Compared with conventional thermal insulation methods, it can increase construction efficiency one time by shortening 60% of the construction period. It integrates low carbon, energy conservation, decoration, fireproof and building aesthetic effect by combining like-dissolving-like binding system installation and bump fixed system, and under long-term cooperation of air handling system and waterproof system. It has excellent outdoor weather resistance, colour?retention, alkali?resistance, water resistance, scrubbing resistance, crack resistance and temperature change resistance, wear resistance, collion resistance and the paint film is firm and durable, with strong adhesive force and mould proof effect. It can provide all-dimensional thermal insulation, decoration, low carbon and energy conservation and fire prevention for construction projects.

Q:What is the definition and classification of amorphous fire resistance materials?

9.8. brick made of refractory bone material and powder material can be used directly or after adding appropriate liquid formulation Refractory paint. Refractory slinging material 6. Prefabricated cubes, bonding agent or other additives. fire-resistance sparying material compround additives. Refractory pressed into the material, binder. Refractory ramming material 3, The material is a new fire proof material without calcination Heavy aggregate and lightweight aggregate: Inorganic binding agent and organic bond, its fire resistance is not less than 1580. Refractory castables 2 mouldable refractory Classification according to the type of bonding agent: 1. Classification according to refractory aggregate. According to the production and construction method, refractory mud or refractory mire, with a certain proportion of the mixture

Q:The development prospect of fire-resistant material

I also want to know, who can say, thanks all the way.

Q:What does fire-resistant insulation coating have?

Refractory thermal insulation material mainly refers to the inorganic thermal insulation material and composite thermal insulation material. According to the shape, it can be divided into: Finishing of fibrous shape, mineral?cotton, rock wool, glass wool, aluminum?silicate?wool, ceramic fiber, etc. Diatomaceous earth of microporous pile, calcium silicate, expanded perlite,expanded vermiculite,aerated concrete, etc. Foam glass of bubble shape, volcanic ash glass, foamed clay, foamed?concrete, gelatine powder polyphenyl granule heat insulating slurry of pasty form, etc. Their common feature is fire-retardant and firproof. It can be used in buildings with high requirements of fire?rating. Calcium silicate, aluminum silicate and asbestos can also be used for piping insulation of heat transport with high temperature.

Q:Who knows what material is in the center of fireproof rolling curtain?

made of inorganic super fireproof rolling curtain: Glass fiber cloth ceramic fiber cloth (reinforced stainless steel wire) ceramic fiber blanket aluminum foil cloth. Hope my answer will help you.

Q:What refractories are used in various parts of the blast furnace.

Blast furnace from top to bottom has the throat, hearth staves, waist, bosh, hearth and furnace bottom. the specific structure is as follows: The throat is the first to be affected by the impact and abrasion, generally use high-density alumina bricks. the upper and central portion of temperature furnace is only 400 ~ 800 ℃, the area with high alumina bricks and silicate bricks. The lower part of furnace is subject to erosion and dust erosion alkali metal vapor due to high temperatures, it is required in such case to use high quality clay brick,high alumina brick,carborundum brick,corundum brick that is slag resistance and alkali?resistance, temperature resustant and wearproof. Furnace bosh temperature reached 1400 ~ 1600 ℃, serverly eroded by slag,vapor, flush. so we use carborundum brick and reaction-bonded silicon?carbide?brick. Bosh temperature reaching1600 ~ 1650 ℃, using alumina brick, corundum brick or silicon carbide brick. the temperature of Hearth near the upper portion of the outlet zone at 1700 ~ 2000 ℃, use of silicate bricks and corundum castable graphite filler, silicon carbide bricks. In 1450 Silly twitch bottom temperature sealing die of hunger slander bet phoenix astringent preserved Grade ~ 1500 ℃, use of graphite bricks and microporous carbon bricks, now use more corundum brick, corundum mullite brick and synthetic mullite brick. x26lt;P class x3d "share-btn"x26gt;

Q:Who knows the fire endurance of B-level fireproof doors and windows?

B-grade fireproof windows refer to those fireproof windows whose fire retardant limit is not less than 1 hour. Technical requirements: I. Materials and Accessories (1) Window frame should have a certain strength to ensure the integrity and stability of the steel frame or the wood frame. (2) Steel frame and mound layer can employ galvanized?steel?sheet or stainless steel plate. Its selection criteria should be in line with the stipulation of the Article 5.1 of GB12955 "General Technical Requirements of Steel Fireproof Doors". (3) The selection standard of wood frame and mound layer should be in line with the provision of Article 5.1.1 of GB14101 "General Technical Requirements of Wooden Fireproof Doors". (4) Filling materials inside steel frame and wood frame should be non-combustible materials.

Q:Does anyone know what is the use of waste refractory materials?

1.Waste refractory bricks can be reused to make the refractory bricks after being crushed by crusher, but the price is not very high. The purchasing price of refractory plant is ?60/ton. Because the refractory material has been calcinated for two times, it becomes easier to make bricks expansion coefficient with waste refractory bricks, but too much is inadvisable. If too much, the refractory materials would have a bad combination, which will give rise to loose bricks and incomplete corners. Nowadays, ordinary refractory plants would purchase waste refractory bricks to produce bricks, but better plants wouldn’t do this.
