- Q: Who knows about the fire endurance of A grade fireproofing glass doors?
- The fire endurance of grade A fire resistance rolling shutter doors should be no less than three hours. Fire doors can be divided into A, B and C grades according to their fire endurance which should be no less than 1.20 h, 0.90 h and 0.60h respectively. Places where are difficult to set fire-proof bulkheads can use fire resisting shutters as partitions of fire?compartments. The fire endurance of fire resisting shutters that include unexposed surface temperature rise as judging condition should be no less than 3 h. Fire resisting shutters that exclude unexposed surface temperature rise as judging condition should set up independent protection of closed automatic water spray system on both sides of shutters, and the duration of water spray system should be no less than 3.0 h.
- Q: What does fire-resistant insulation coating have?
- Refractory thermal insulation material mainly refers to the inorganic thermal insulation material and composite thermal insulation material. According to the shape, it can be divided into: Finishing of fibrous shape, mineral?cotton, rock wool, glass wool, aluminum?silicate?wool, ceramic fiber, etc. Diatomaceous earth of microporous pile, calcium silicate, expanded perlite,expanded vermiculite,aerated concrete, etc. Foam glass of bubble shape, volcanic ash glass, foamed clay, foamed?concrete, gelatine powder polyphenyl granule heat insulating slurry of pasty form, etc. Their common feature is fire-retardant and firproof. It can be used in buildings with high requirements of fire?rating. Calcium silicate, aluminum silicate and asbestos can also be used for piping insulation of heat transport with high temperature.
- Q: which kind of refractory is used in golden smelting furnace? How about his using temperature
- generally the price of the quartz sand refractory material is higher and the temperature can meet the requirement of 2000 degree.
- Q: Where is the distributing center of refractory materials in China?
- Refractories industry is one of the pillar industry of Gongyi City, the city's existing more than 300 refractory enterprises, the annual output value of 10 billion yuan, accounting for three of the city's GDPA share of the domestic market share of about 30% of refractories. Production of stereotypes, not stereotypes of two kinds of aluminum, magnesium, silicon and carbon four series of more than 1000 varieties of products, covering the whole country, and exported to Europe and other regions, is one of the Chinese refractory base. Yongan Road Subdistrict Office area is the center of the hinterland of refractories industry, Yongan is the theme of economic development, Chinese, Gongyi refractory chemical professional market, location, close to the aisle 310, Henan Provincial Highway S31, Yongan road and the construction of the Gong Teng speed transportation is very convenient.There is a good space for development and a relaxed business environment. Very conducive to customer management and development, is conducive to the full enjoyment of preferential policies in Gongyi, backed by trees good shade, head blue sky good development.
- Q: Is there requirement for radiation indicator in refractory?
- All refractories have no radiated harm to environment, so there is no requirement. From the elemental analysis, magnesite. I do not know it is helpful to you. But for refractory rwa material, any chemical element is radiated, including silicon?dioxide; If they are radioactive. From the use analysis, such as bauxite, do not have use value.
- Q: What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?
- I am not quite clear. But you should take two aspects into consideration, namely, no pollution and strong durability.
- Q: What is the appropiate thickness if fire resistant time for ultra thin steel structure coating is 2.5 hours?
- Hello steel structure can adopt surrounding concrete or brick, fireproof coating, fireproof board coating and composite structure for its fire resisitance. Fire resisitance board can be divided into thick fire protection plate and thin plate, the thickness of the plate thickness of the fire is between 20 ~ 50mm, mainly includes calcium silicate fireproof board and expansion boring stone fire board, the main varieties are KB board, CF; thin fireproof plate is between 6 ~ 15mm thick, the main varieties include enforced short fiber cement plate, ordinary enforced fiber silicate calcium board and glass cloth reinforced inorganic board.
- Q: Is the linear change on reheating the same as heating permanent linear change of refractory material?
- “+”represents expansion. the afterexpansion and aftercontraction after cooled to be at room temperature. The change may significantly damage the masonry of thermal kiln. There are regulations on the linear change on reheating of common refractory material in the national standard. Some physical chemical changes may continue. It is defined as the change from being heated to the specified temperature of refractory material sample. Heat preserving for a while till afte cooling to be at room temperature, then the residual will expand or contract in its length, heat preservation for a while, organization vitrification, the irreversible changes of its length refers to heating the firing refractory to be at high temperature, so as to make the volume of refractory materials expand or contract, due to the influence of uneven temperature or lack of time, otherwise it will cause the deformation of the refractory ball and make this indicator within standard even reach smaller value, so firing control must be strengthened in product production. But it is should not be too high. For refractory materials with same chemical composition, the linear change on reheating is produced in the heating process. Properly increasing sintering temperature and prolonging the holding time is an effective process measures, make its firing inadequate. When subjected to high temperature, it can reduce the thermal shock resistance. Minus sign "-" represents contraction. The permanent line rate refers to heating the fire refractory ball to the specified temperature. Linear change on reheating, also known as residual linear change, is an important indicator to assess the quality of refractory in the long time use. To control the permanent line rate within the standard or reach the minimum value.
- Q: What is the difference between the fire?rating and the fire resistant level of the fire-fighting equipment?
- Hello there. Fire rating and fire-fighting rating are the misnomer to the building fire resistant level. The building fire risk is measured by fire resistant level. The article 3.2.1 and 5.1.7 of "Architectural design code for fire protection" have made provision respectively on the fire resistant level of plant (the storeroom) and civil construction. Article 3.0.2 of "Code for fire protection design of tall buildings" has made provisions on the fire resistant level of tall buildings. As for the warehouse building "category malonate", it refers to one of the fire risk of goods storage, which is divided into A, B, C, D, E, and each category is refined depending on the nature of different substances. "Malonate class" specified in article 3.1.3 of "building design for fire protection" refers to the flammable solid.
