- Q: Does anyone know the refractory temperature of fire-resistant glass?
- Ordinary glass will be completely liquefied in the furnace of about 1100 degrees for half an hour and will not deform below 600 degrees. toughened glass fire-resistant glass is the product of ordinary glass after being processed Glass will mainly burst after encountering fire. When unevenly heated or encountering sudden drastic changes in temperature, ordinary glass will burst if the sharp temperature difference is over 70-120 degrees and toughened glass will burst at 200 degrees. It is not yet clear of the bursting temperature for the refractory glass. If the overall glass is not heated evenly, it will have no significant change below 600 degrees, and it will deform with the increase of temperature until melting. The fire-resistant time of the glass you said is the time to heat the glass into the extreme temperature differences it can endure, which should not be more than 10 minutes
- Q: Kinds of refractory mortar
- Refractory mortar can be divided into ordinary refractory material and special refractory material. Ordinary refractory materials can be divided into acidic, neutral and alkaline refractory materials chemical properties. Special refractory material can be divided into high temperature oxide, refractory compounds and high-temperature composite materials according to their components. Furthermore, according to refractoriness, it can be divided into general refractory products (1580 ~ 1770 ℃), high grade refractory products (1770 ~ 2000 ℃) and super refractory products (2000 ℃ above). It can be divided into bulks (standard bricks, special-shaped bricks, etc.), special shapes (crucible, sagger, pipe, etc.), fibrous (aluminum silicate, zirconia filter and boron carbide , etc.) and indefinite shape (refractory clay, pouring materials and ramming mass, etc.). According to the sintering process, it is divided into sintered products, fused cast products and melting jetting products.
- Q: Using what kind of melting aluminium furnace refractories is more appropriate?
- If it's the ordinary, you can use high aluminum refractory brick with general clay, GB/T 3994-2005 clay heat insulation refractory brick. If you need these with good material, there is high alumina thermal insulation refractory brick, GB/T 3995-2006 high aluminum heat insulation refractory brick, models have A13 and material is the alumina, A13 50 u, high insulating brick B5.Intermediate insulating brick B2, etc. Dolomite brick: good hang kiln performance, good erosion resistance, but brick is usually without f - CaO, hydration, and difficult to transport and storage, less used in the production. Magnesia-chrome bricks: good hang kiln, used in calcining zone. The disadvantage is that its thermal shock resistance is poor and plus hexavalent Cr is toxic, the production and use of magnesite chrome bricks in international countries gradually reduce. Now unit using the brick find replacements as soon as possible.
- Q: how to divided the external wall thermal insulation materials fire rating
- The external wall thermal insulation materials is divided by fire rating: 1. The thermal insulation material of level A combustion performance: inorganic fiber spray coating, glass wool, foam glass, foamed ceramics, rock wool, foam cement and hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
- Q: Which brand of AAA refractory is good?
- The most famous is fire dragon. The Morgan and Lu Yang are all very good at making common thermal insulation material. The price is not very expensive, and the quality is comparatively good. The refractories are capable of good thermal shock resistance ability and chemical errosion resistance ability It is a non-metal material with a low heat conductivity coefficient and expansion coefficient. It requires high temperature in nature. The production base of silicious thermal insulation board is difficult to transport raw material. The silicious thermal insulation board is a high temperature thermal insulation material with the raw material of non-porous refractory?aggregate and porous refractory?aggregate, organic fiber and inorganic fiber.
- Q: What does refractory mean?
- Basic refractory material generally refers to Magnesium Oxide or Magnesium Oxide and calcium oxide as the main component of refractory materials. This kind of refractory material has higher refractoriness and strong resistance to alkaline slag.
- Q: What types does refractory floor include?
- The categories of refractory are: 1. the best overall performance stone flooring (waterproof, fire retardant) The full name is microcrystalline stone flooring. It is a high-performance waterproof and fire-retardant environmental wood floor synthesized with high and new technology. Its unique raw material is ground calcium carbonate micro-crystalline polymer stone with natural resin and other twenty more imported spreadings. It is formed by refining with high temperature (300 degree centigrade) and high pressure (9,000kg). It is an environmental healthing high-performance material. Its product is innocuous and unpoisonous, and won't age, deform, fade while it is fire retardant, waterproof, maintenance-free and quality, so it is an inevitable repalcement with traditional wood floor. This product has been confirmed as national key promotion program. 2. Wear-resistant composite solid wood floor It is also known as super wear-resistant multi-layer solid wood floor. First stiffening layer surface (based on inorganic materials and steel fibers for paper impregnated with thermosetting amino resin with solid wood or plywood blockboard substrate surface as a combination of facing layer), the front is wear-resistant layer, and the back is balance layer. Thtough hot pressing, it is a grooved and tongued floor, a new impregnated paper laminate floor. It also has the same wear-resistant quality as laminate floor, beauty and foot feel as solid wood floor, stable structure as solid wood composite floor, etc. 3. Waterproof plastic wood floor Plastic wood (also known as "wood plastic" or "plastic wood") composites, and the English name is WOOD-PLASTIC-COMPOSITES, WPC for short.
- Q: Could you tell me the fire-resisting time of class B fire proof door?
- Could you tell me the fire-resisting time of class B fire proof door?
- Q: Which refractory is suitable for the tunnel kiln?
- Shuttle kiln refractories requires the good thermal shock properties. Because the tunnel kiln is continuous firing furnace, the temperature in the kiln is long time stable and with little fluctuation. The shuttle kiln is intermittent kiln firing. The temperature in the firing kiln is adjusted by the firing curve. It is with a relatively short time and serious fluctuation. The seal and kiln car take use of the heavy corundum brick. If it is continuous kiln, the alumina hollow ball bricks are used in the burning zone. The seal of the burning zone takes use of the kiln car brick and the seal takes use of the heavy corundum brick.
- Q: Are there any differences between insulation and refractory materials ?
- Refractory materials can resist more than 1200 degrees, some of which are not insulation materials, such as firebricks, which can directly contact with heat source, has little insulation effect. Ceramic fiber, high silica, etc. are all refractory materials which can insulate. Insulation materials with poor performance usually is lower than 800 degrees, which have large thermal resistance, and low thermal conductivity, high porosity. Thus they reduce the thermal loss. To put it simply, insulation materials store most of the heat and only let a small part of heat lose through the air, thus the heat has been isolated. Glass fiber, rock wool, flexible material for thermal insulation, etc.
