- Q: How to divide the fire resistant level of EVB?
- Inorganic materials: Level A incombustible material is mainly divided into three levels, which attributed to two types of materials! Inorganic materials: Rock wool, foam cement, vitrified micro bead, foam glass organic: Eps xps polyurethane phenolic aldehyde, polystyrene particles are divided into two manufacturing techniques including field fabrication and pre-production polyurethane - now sprayed, precast slab eps, xps, phenol - now posted, precast slab (composite board)
- Q: What requirements should refractory materials meet?
- The operating temperature of forging furnace is above 1000, which can ensure the normal operation of the furnace, prolong the life of the furnace and save energy. General requirements for refractories are as follows. 1 They should deform at a sufficient temperature without melting. 2, They should have necessary structural strength without softening and deforming. The volume should be stable at high temperature without expansion, contraction or cracking. 4, They can resist erosion of molten metal, slag, gas and other chemicals.
- Q: Refractory material, refractory brick
- 1, according to the degree of refractoriness:Ordinary refractory material: 1580 ~ 1770 DEG CAdvanced refractory material: 1770 ~ 2000 DEG CSuperfine refractory material: >2000 DEG C2, depending on the shape and size of the product:Standard type: 230mm * 113mm * 65mm;No more than 4 measurements, (size ratio) Max:Min<4:1;Profile: no more than 2 concave, (size ratio) Max:Min<6:1;Or an acute angle of 50~70 degrees;Specific type: (size ratio) Max:Min<8:1;Or not more than 4 or a sharp angle; 30 ~ 50 degrees;Special products: crucibles, vessels, tubes, etc.3, according to manufacturing methods, refractory materials can be divided into:Fired products, unfired products, unshaped refractories4. classification according to the chemical properties of materials:Acid refractory material, neutral refractory material, basic refractory material
- Q: The effect of a high content of water in liquid resin exerted on refractory material?
- For one thing, Substandard whiteness, transportation, low quality and the storage of refractory material may account for this. For another, a high content of moisture reduced the performance of refractory material. A high content of moisture is equal to buy water with same money in terms of trade settlement. Based on this, we can’t consider the super-standard water content from a single aspect, because the water content in refractory material is definitely super-standard, and another problem is particle size. Many people hold the idea that excessive amount of water content may revive its original performance, but it tends to have influenced the quality of refractory material.
- Q: As for fireproofing material rock wool and glass wool, which one is better?
- First of all, glass wool and rock wool fireproof materials, rock wool and glass wool belong to Class A fireproofing rating, secondly, rock wool can endure high temperature of 800 degrees, glass wool high temperature of 450 degrees, again,unit weight of rock wool is relatively heavier and unit weight of glass wool is lighter, finally, glass wool has better waterproof performance.
- Q: How should refractory cement be used?
- Types of refractory mortar Refractory mortar can be divided into the following types: casting of fire mortar: also known air setting fire mortar. It is used as a protective refractory layer in the kiln head burner, as a refractory material in some parts of preheater, and it is generally constructed by grouting. b: Insulation fire mortar: It is used to repair the deformed plane of the kiln shell, or for thermal insulation of the roof in the cooler. Refractory mortar: It is also known as thermosetting fire mortar, mainly used in brick masonary. When using, we must add the glassy water to stir. (silicic acid sodium, water, NaSiO3, H2O). General DiDOTECT 135 (having a heat resistance of above 1350 degrees Celsius) SK34 is used in the kiln tail. DiDOTECT 150 (having a heat resistance of above 1500 degrees Celsius). SK35 Couprit 160H is used under high temperature, and it is mainly used in the kiln head coal injection nozzle.
- Q: How long is the duration of fire resistance that fireproof door of level B can endure?
- The national standard for fireproof door of level B is 1.5h, which must be achieved. The data GB12955-2008 means that the door leaf of raw material is 0.8mm-1.2mm in thickness and door frame is 1.2mm-1.5mm in thickness. And other metal melting temperature shall not be less than 950℃, the duration of fire resistance shall not be less than 0.9 hours. Fire department will check and accept based on the manufacturer's inspection report, so you have to refer to manufacturer's inspection report if you want to know more in detail.
- 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: Does anyone know fire-proof material of fireproof wooden door?
- Because the timber of fireproof wooden door has gone through fire retardant treatment, so it can prevent fire. Its principle: Fire-retardant treated timber has become flame retardant material itself and its fire endurance has increased. The commonly used method of fire retardant treatment for timber including: Spraying method, soaking method, boiling method, vacuum method, vacuum-pressure method. Spraying method and soaking method are generally used for timber surfaces which are no longer going through planing process, and thin plate fire retardant treatment, whose thickness is less than 10mm . Vacuum method and vacuum-pressure method have excellent flame retardant efficiency, but their equipment are expensive. Fireproof wooden door refers to the door whose fire endurance of door frames, skeleton of the door leaf, door panels made of timber or timber work reaches the provisions of "GB50045-95 design of tall buildings for fire protection".
- Q: What are the differences between thermal?insulation?material and refractory?
- Just as its name implies, Thermal insulation means that it doesn't conduct heat instead it insulates heat inside, while refractory means resistance to high temperature and it will not be out of shape or damaged due to high temperature.
