Q:What is the interior fireproof thermal insulation material?
The methods of thermal insulation wall have three kinds of materials. First: gypsum board or cement board are stuck outside the polyphenyl board; second: lightweight brick build; third: infill polyphenyl board, lightweight brick is built outside. The first two has almost the same price. The latter is slightly expensive. 60 yuan / square meter is not very expensive!
Q:How to choose construction external wall thermal insulation and fireproofing materials?
The width of fireproof partition shuld be greater than 30CM, and the thickness should be the same as total thickness of thermal insulation materials. Fire barrier zone thermal insulation board and base wall should be stuck in whole area. Fire Barrier zone thermal insulation board should be stuck with the assistance of anchor bolt which must press the mesh of the bottom layer. Fire Barrier zone should be set above the door and window, with a distance of less than 50cm between the lower edge of fire barrier zone and the upper edge of window.
Q:what needs to be noted when choosing and using blast furnace fireproof materials?
it depends on the size of the blast furnace. below 200 cubic meters alumina bricks and carbon brickcan be used. 200 cubic meters and above are currently integrated bottom, not the same as the size of the cubic level, varying in the use of refactory. I hope my answers above are helpful to you and your ideal anwers.
Q:Which are fireproofing external wall materials?
For example, Grade-A waterproofing external wall thermal insulation material: glass wool, foam glass, foam cement, hole-closed perlite, rock wool; Grade-B1 waterproofing external wall thermal insulation material: XPS after special treatment. There are also PU after special treatment, phenolic aldehyde and gelatine powder polyphenyl granule. Grade-B2 waterproofing external wall thermal insulation material: PE, and EPS. Grade-A: Completely fireproofing buliding material. Without probility of burning, completely fireproofing buliding material is expensive and unnecessary for home decoration. It is usually used in arsenal and electrical equipment department store. Grade-B1: nonflammable building material: With good flame resistance, nonflammable building material will not burn in the air or at high temperature, but it maby burn in the air and at high temperature. But when the fire source ransfers, it will be out immediately. Grade-B2: combustible building materials. Due to its small firresistance, it is easy to burn in the air or at high temperature, such as wooden building materials. The above are external wall fireproofing material of different classes.
Q:which kind of material is chosen for fireproofing window?
(1) the inside filler material of steel, wood frame should use incombustible material. (2) window frame uses steel frame or wooden frame with certain strength that can safeguard the integrity and stability of the components. (3) steel frame and mound layer can choose galvanized steel sheet or stainless steel plate. Its selection criteria conform to the article 5.1 in GB12955 Steel Fireproof Door General Technical Condition. (4) the selection criteria of wooden frame and mound layer should conform to the article 5.1 in GB12955 Wooden Fireproof Door General Technical Condition. (5) fire-resistant glass can choose test approved products without affecting the fire resistance of fireproofing windows . Light transmittance of glass should not be less than 75% of same layers commom sheet glass. (6) the sealing material between the frame and the fire-resistant glass should use flame retardant materials, it can play a role of fireproofing and smoke insulation in the fire. (7) hardware accessories should be tested qualified approved supporting product.
Q:Who knows the texture of fire-proof wooden door material?
The so-called fire doors are only posted a layer of fireproof material. Door selection still depends on the timber inside. The simplest way is to see the weight value, fireproof material layer, and they are generally paint-free doors. With fireproofing function.. Hope you adopt.
Q:What is molten silicon? What refractoriness do refractories made by it have? What properties of using does it have?
Molten silicon can be called quartz glass, which shows an amorphous silicon state. It is a liquid fusion at above 1723 degree and is an ultra-cooling state at low temperatures. It is not generated in refractories, but generated in the matrix, showing liquid state at a high temperature capable of buffering the stress with somewhat binding properties. If quartz glass is used as refractory, its function are melrly these ones. (These are what I konw for reference only.)
Q:What's the fire endurance of hollow brick?
This question is really very simple. It is better no to exceed 1050℃, or it will be easily burnt. I think 980℃ is ok actually. Around 950℃, no more than 1100℃, or brick will be burnt and melted easily.
Q:Who can tell me what is neutral refractory?
Refractories mainly refer to aluminum oxide, chromium oxide and carbon as the main component of refractory materials, such as corundum brick, high alumina brick, and carbon brick. Its characteristic goes to the resistance to both acidic and basic slag. Basic refractories mainly refer to the refractory materials whose mian components are magnesium oxide and calcium oxide, including magnesia bricks, magnesia-alumina bricks, magnesia chrome bricks, dolomite bricks, etc. Basic refractory is good at resisting basic slag erosion.
Q:How much is the duration of fire resistance of the porous brick shale?
This is really a simple question. The temperature should be limited within 1050℃, or it will be scorched. I think 980℃would be acceptable.
