Q:what textures of furnace refractories are good?: Common ceramics use ordinary clay and high alumina bricks, as well as thermal insulation bricks, calcium silicate boards and fiber cotton. The vessels fired with potter's earth are called pottery, and the vessels fired with porcelain clay are called porcelain. Ceramic is generic term of pottery, stoneware and porcelain. The objects taking the two different types of clay as the raw materials, like, potter's earth and porcelain clay, and made through the technological process of ingredients, forming, drying and roasting, ect. can be called ceramics.

Q:Who knows the external wall thermal insulation materials fire rating requirements?: 1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, 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: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 Level A insulation material is only for fireproofing, but its thermal insulation performance is not better than organic XPS \\ EPS and other materials. I feel the best insulation materials should be modified phenolic board, which can keep insulation and fireproofing, but the unit price is very expensive. Insulation materials in the domestic market have some disadvantages, it is better to considere the materials within the acceptable range in the building needs.

Q:Is there a worker in (Jigang refractory plant)?: Units in this way, it is necessary to slowly boil it, wages will come up. You are a labor worker, and can not share with the stock system staff. There's a difference between salary and vacation.

Q:What are refractory materials?: Refractories can be divided to two categories based on the shape and three categories according to the chemical nature of acidity, neutralily and alkalinity. Alkaline refractory materials are magnesia-carbon brick, magnesia chrome brick, calcium magnesium brick and magnesia-chrome bricks. Neutural refractory mateial are high alumina brick, corundum brick and clay brick. Case-hardened refractory materials are castable, ramming mass, gunning mix, coated mix, dry vibration material, etc.

Q:Who knows the refractoriness of high temperature lightweight firebricks?: The disadvantage of light refractory bricks is its poor thermal insulating ability and the advantage is its endurable heat resistance property. The temperature range and main features of thermal insulation refractory are as follows. Diatomite brick

Q:Which one is better, fire-resistant wood or steel?: From the aspect of low-carbon and environment protection, the steel and timber structures are both OK, they are both renewable resources, the steel can be recycled and melt down again and wood can continue to be planted. Fireproof board Fireproof board is a refractory material used for surface decoration. It is widely used in interior decoration, furniture, kitchen cabinets, laboratory tables, walls, and other fields.

Q:What 's the highest temperature can magnesium plate glass resist ?: 2 hours, according to the fire resistance test report, 2h

Q:Who knows the highest temperature the high-temperature refractory coating can resist?: The temperature resistance degree of high temperature coating is different according to different coating types. The temperature resistance degree is vary from tens to thousands, magnesia brick: Greater than 2000 degrees dolomite brick: Greater than 2000 degrees casting corundum brick: Greater than 1990 degrees. The above data come from the network, for reference only.

Q:Can anyone tell me what material the first rate fire resistant door is?: Class A fire door materials are mainly steel, wood, steel and wood,and other materials. If there is filling material in a Class A fire door, it is generally the perlite. According to the actual situation in China, the fire doors and windows are divided into class A, class B, class C, whose minimum fire endurances are stipulated, namely class A 1.50h, class B 1.00h, Class C 0.50h. There are fireproof wooden doors and fireproof steel doors. whose main purpose is to achieve fire endurance time. But door closers are required to be installed.

Q:What type of firebrick does TZ-3 represent?: It is the standard brick.
