- Q: Where is the production of refractory manganese alloy manufacturers? Manganese is recommended between 63 and 70!
- There are a lot of silicon manganese alloy manufacturers, production market is relatively large, the manganese content in manganese alloys between 63 to 70 or more common
- Q: Who knows how many fire heat preservation material are there?
- Fire proof board is a fire refractory building material for surface decoration, widely used in interior decoration, furniture, kitchen cabinets, laboratories mesa, walls and other fields. Fire board is base paper (titanium powder paper, kraft paper) processed by melamine and phenolic resin, high temperature and high pressure. 1 mineral wool board, glass wool board: mineral wool, glass wool insulation. It does not burn itself, have good performance such as high temperature resistance, light quality. Such plate have evolved into plate with inorganic adhesive material as base material, mineral wool, glass wool as reinforcing material plate. 2 cement board: High strength, wide source. In the past, it is used to make fire prevention ceiling and partition wall, but its fire resistance is poor. Cement concrete component has good heat insulation and sound insulation performance. It can be used as the partition wall and the roof panel.
- Q: In entering fire door, which material does well?
- Entering door has two kinds: security doors, fire security door. The pure fire door does not have anti-theft function. In the relevant technical standards of fire doors : when in the fire, it can make residents in a few seconds or 1 minutes forget to open the door... The material of fire door, fire door has steel fire door and wooden fire door. There is no doubt that wooden fire door can't be used as entering door. In the steel fire door, two layers of steel plate in the clip is flame retardant material.
- Q: Who knows the fire rating of fire?partition with steel stud?
- Partition system made by fire?partition with steel stud and high-quality keel has good fireproofing performance and is non-combustible sheet. Flame burn duration is zero. It does not burn at 800℃, and it is without flame at 1200℃. Its fire resistance rating reaches GB8624-A standard through test, which reaches the highest fireproofing and non-combustible level grade A1. 10MM fire endurance can reach up to 4 hours fire resistance maximum limit. It can absorb a lot of heat during the process of burning and delay the rise of temperature in surrounding environment.
- Q: Would you like to know if there are any enterprises in Mianyang that need fire-resistant materials?
- I only know that the Stone Town Youxian district with a fire stopping collar.
- 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: Can anyone say something about what A-level fire-proof decorative material is?
- Combustion performance rates of decoration materials ratess combustion performance of decoration materials A incombustible B1 flame retardancy B2 flammability B3 high flammability The B1 rate combustion performance of gypsum plaster board and mineral wool acoustic panel absorber installed on steel joist can be used as A-level decoration materials. Inorganic decorative coating applied on the A level substrate can be used as A level decoration materials. Hope you adopt
- Q: which is better as household fireproof material ?
- the thickness recommended is 1mm or more # 304 stainless steel plate, refractory corrosion-resistant, easy to clean. It now appears that among the most common fireproof material, asbestos is the best. But the asbestos harmful effect is also great, especially for lung damage. Now on the market, the polyurethane, polystyrene, rock wool glass wool, phephenolic aldehyde fireproofingthermal insulation board. But now the phenolic aldehyde fireproofing thermal insulation board has superior performance! phenolic aldehyde containing only carbon, hydrogen and oxygen atoms, when subjected to pyrolysis, except small amounts of CO gas, the other will not produce toxic gases, maximum smoke density is 5.0%.
- Q: How many levels are there in the classification of PP fireproof materials?
- PP fireproof materials level V-0: After two 10-second fame tests on the sample, the flame extinguishes within 30 seconds. Inflamer can not drop. V-1: After two 10-second flame tests on the sample, the flame extinguishes within 60 seconds. Inflamer can not drop. V-2: After two 10-second flame tests on the sample, the flame extinguishes within 60 seconds. Inflamer can drop.
- Q: What's the commonly used refractory material for ladle?
- Commonly used types of refractory material for ladle are as follows: high-alumina brick, clay brick, magnesia-carbon brick, aluminum carbon brick, magnesia chrome brick, spinel brick, corundum brick, high alumina castables, aluminum silicon carbide carbon castables, refractory castables for ladles, magnesium castables, magnesia chrome spray coating, dry vibration materials, etc. Hope it's helpful for you!
