- Q:Physical and chemical indicators of various refractory.
- There are too many of them.
- 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..
- Q:Does anyone know the difference between refractory and thermal insulation material?
- Refractory refers to inorganic nonmetallic material, whose refractorinessis not less than 1,580℃, but refractory is not necessarily insulated material. Inorganic thermal insulation material also belongs to refractory as long as its refractoriness is higher than 1580℃.
- Q:What are grade classifications of the external walls fireproofing material?
- There are many kind of external walls fireproofing material, according to the document No. 65, the grade of external wall fireproofing material can be divided into: Level A is inorganic insulation non-combustible materials, such as cement foam insulation board, vitrified?micro bead?thermal insulation?mortar, rock wool board, glass wool panels. Level B1 is nonflammable material, mostly are organic material which has added a relatively large amount of flame retardant, such as polystyrene board, extruded sheet, phenolic foam board and polyurethane board. Level B2 is flame-retardant materials, and also known as fire-retardant materials, mostly are organic insulation materials with appropriate amount of flame retardant.
- Q:which kind of fire?bulkhead is better?
- I think fire bulkhead is good, fire bulkhead also known as non-combustible fire retardance board, and it's made by various incombustible?material after the scientific pressing, and has good flame resisting properties, it's non-combustible time can reach over 3 hours, high mechanical strength,it has characteristics of non-explosive, water and oil resistance, good chemical corrosion resistance and non-toxic.
- Q:Who knows about the fire endurance of sintered shaly hollow bricks?
- 1. after roasting at high temperature of more than 1200 degrees, shale burned bricks in construction works can be free from expanding with heat and contracting with cold. 2. masonry walls can be plastered with no needs of any anti-cracking, reinforcement measures, and walls will not bulge and crack, which can reduce the construction cost, as well as are preferred building materials of frame structural engineering. 3.They have good sound insulation and thermal insulation performances, are one of the green building materials that the state currently promotes. 4. They have high intensity. The average compressive strength of them is up to 15.8, which matches with M7.5 cement mortar that has advantages of low water absorption, and good anti efflorescence performance.
- Q:What's the fire endurance of fire windows?
- Fire endurance of fire doors and fire windows stipulated by the fire prevention norm: Fire endurance of A class fire door or fire window is 1.2h rather than 1.5h, and fire endurance of B class fire door or fire window is 0.9h rather than 1.0h. Fire prevention code doesn't explicitly state that the fire door has thermal insulation function, so it can definitely be interpreted that the fire door only has fire integrity. For the fire door without heat-shielding performance, at certain distance from the unexposed surface, it has strong thermal radiation and is easy to hurt people. For the A class thermal insulating fire door, its fire integrity is 0.1h shorter than that of the corresponding fire door stipulated in the specification, but its heat-shielding performance and integrality is improved. All in all, compared with the specification that the fire integrity of the A class fire door should be 0.6h, it has much more improved its performance.
- Q:What is the difference between wear-resistant material and refractory material?
- However, the purity and the requirement are not the same. For example, brown emery is often used in abrasive paper, which doesn't matter. Refractory material uses brown corundum brick. The material used in texture and refractory material of abrasive is different. For example, it is to facilitate their forming and easy sintering. However, some other materials should be added when making brown corundum brick. In general, some top grade materials are used to make abrasive.
- Q:Which industry does refractory belong to? Does it belong to construction industry?
- I am engaged in construction. Refractory material does not necessarily belong to construction industry. Fire resistance is only a part of material?performance. Indeed, there are many places requiring refractory accorded with fire resistant level.
