- Q: What advantage and disadvantages it has compared to common fire insulation materials
- Advantage and disadvantages of A-level heat perserving materials of equal effectiveness 1, the component materials of A level thermal insulation materials are inorganic materials, so it is high temperature resistant, non-combustible, fire-resistant; 2, good durability, aging resisitant, and having the same service life as buildings; 3, a level thermal insulation material can be well combined without using polymeride to bond, coat mortar, reinforced net, needing only few construction procedures. It is anti seepage with few quality problems; 4, absorb few water, and can bond firmly with the cement mortar, tile adhesive tile, safe and reliable; 5, a level thermal insulation material have the same service life as buildings, without the need to increase the cost on maintenance and renovation during its life span, and can maximize resource conservation.
- Q: What are the fire protection standards of insulation materials?
- According to the three versions of GB8624 (1997,2006,2011), the fire rating of external walls can be basically divided into: A1-, A2-, B1-, B2-, B3-level. The detailed divisions are determined by many technical indicators. It is a very professional and technical long story. Please contact QINGDAO SHANFANG INSTRUMENT CO., LTD for detail information, they are specialized in manufacturing fire rating testing instruments of external walls.
- Q: What are the meanings of azs, 34% and ec in fused brick?
- The fused brick, also called zircon corundum brick, is shorted as AZS for three chemical components in Al2O3-ZrO2-SiO2 ternary diagram. I don't know the meaning of EC.
- Q: What's the refractory material?
- Main components of basic refractory are magnesium oxide and calcium oxide, and magnesia brick is commonly used. For the magnesia brick with magnesium oxide content of more than 80%-85%, it has good resistance to basic slag and scum, and it has higher refractoriness than that of the clay brick and silica?brick. It is mainly applied to the open hearth furnace, oxygen-blown converter, electric furnace, non-ferrous metal smelting equipment and some high-temperature devices.
- Q: How to use fireclay?
- Fire-resistant adhesive material is needed, its effect equals to the cement. Cement will certainly do.
- Q: Which are fireproofing external wall materials?
- 1. Acording to national standard GB8624-97, the combustion performance of construction materials are classified as: Grade-A: incombustible building material: Grade-A WW thermal insulation material which hardly burns. Grade-B1: nonflammable building material: nonflammable building material has good flame resistance. It is difficult to burn or spread in the air or at high temperature. Grade-B1: nonflammable building material: nonflammable building material has good flame resistance. It is easy to burn in the air or at high temperature, thus spreading the fire, such as wooden column, timber roof truss, timber beam and wooden stairway. Grade-B3: inflammable building material. Without fire resistance, inflammable building material is easy to burn and thus cause a fire. 2. According to fireproofing performance, external wall thermal insulation materials can be classified as: 1. Thermal insulation material with Grade-A combustion performance: WW inorganic thermal insulation material, rock wool, glass wool, foam glass, foamed ceramics and foam cement. 2. Thermal insulation material with Grade-B1 combustion performance: XPS panel after special treatment/ PU, phenolic aldehyde, gelatine powder polyphenyl granule after special treatment. 3. Thermal insulation material with Grade-B2 combustion performance: EPS, XPS, PU, PE, ETC.
- Q: Who knows about the differences between 3M fireproofing materials and ShiLiDe materials?
- ShiLiDe materials are relatively poor, and have nothing to do with 3M at all. 3M is a brand! 3M company is famous for innovation around the world. It has developed a variety of products in a hundred years, involving in automotive, chemicals, telecommunications, construction and other fields. 3M automotive aftermarket has more than 3,000 products (more than 20% of which are high-tech patented products). The world's first explosionproof and heat insulating film, and the first waterproof abrasive paper were born in 3M Company. The abraser, polishing materials, mirror finish of paintwork, the internal and external auto beauty of 3M Company rank the first place in the world. 3M films are divided into conventional films and crystalline auto films. The conventional films of 3M generally have five-layer structure, the base of films is a polyester film which is s plastic film of tearing and puncture resistance. The film is coated with thermal insulation layer, ultraviolet isolation?layer, adhesive layer, wear-resistant layer, and protective layer which finally becomes thermal insulation and explosion-proof film with metal sputtering method. Optical micro-attach technology is used in the polyester?film which is the base of 3M crystalline auto film. It is coated with more than 240 layers of optical coatings in order to achieve better thermal insulation performance, and be the top anti-explosion and heat-insulating film with clear sight. I hope my answer can help you. Thank you.
- Q: what's the requirements of refractory for forge furnace?
- operating temperature of forge furnace is 1000 ° C, reasonably choosing refractory for build furnace has an important meaning for guaranteeing the normal operation of the heating furnace, improving the service life of furnace and energy saving. general requirements for the properities of refractory: 1, it should be equipped with the properity of no deformation and melting under certain temperature. 2, it should be equipped with the neccessary structural strength without softening deformation in high temperature. 3, volume stability at high temperature, brick body won't be deformation or cracked due to expansion and contraction; 4, not broken and peel off under rapid changes of temperature or uneven heating; 5, resistant to chemical erosion of molten metal, slag and furnace gas,etc.
- Q: who knows the fire endurance of fireproof coating?
- It's fire endurance is 3hours. Fire endurance test of certain building components showed by standard time temperature curve from the starting of fire to lose of supporting capabilities or its integrity or fireproof property. unit time is one hour.
- Q: Which refractory is better for building 1500 degree kiln ?
- The top and wall use alumina hollow ball brick. If it is cubic kiln, the kiln bottom should use heavy corundum brick. If it is continuous kiln, burning zone should use alumina hollow ball brick, burning zone seal and kiln car face brick. If it is pit furnace, curved seal should use heavy corundum brick, and furnace wall and top should use alumina hollow ball brick. That depends on what kind of kiln it is. Curved seal and kiln car should use heavy corundum brick. You can add me friends to have further talks.
