- Q: hat kind of fire retardant materials are there
- At present, there are mainly organic and inorganic flame retardant materials, halogen and non halogen. Organic flame retardant materials are represented by bromine, nitrogen and phosphorus and its compounds; Inorganic fire retardant materials include antimonous oxide, magnesium hydroxide, aluminum hydroxide, and silicon. Generally speaking, organic flame retardant materials have a good affinity, and can be added in the plastics. Brominated flame retardant agent occupy the absolute advantage among organic flame retardant system, though it’s “controversial” in terms of environmental protection, it has been difficult to have other flame retardant system replaced.
- Q: Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?
- Solid wood logs are necessary. If it is the type of smoke free material, it will not be necessary. You'd better confirm it with the port of destination. Vietnam has the requirement to smoke
- 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: What's the requirements of fire-fighting criteria of heat insulating material?
- Specific provisions go as the following article 8: roof grassroots adopted duration of fire resistance is the non-combustible component that shouldn't less than 1.00 h's. Its roof insulation materials should not be below B2; Otherwise, the combustion performance of insulating material should not be below the B1 level. Article 9: The junction of the roof and wall, the insulation layer around the opening part of roof should use the grade A thermal insulation material to set level fire-fighting belt that width is not less than 500 mm. Article 10: the roof waterproof membrane or flammable insulation layer should adopt incombustible material to cover.
- Q: What is the function of refractory in ceramics?
- It depends on what purpose you want to achieve. At the same time, part of special ceramics belongs to refractory. If is is to produce ceramic products, the aforesaid answers are very comprehensive.
- 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 tell me which materials are fire-proof high temperature resistant material?
- Fireproof high temperature resistant materials such as: Quartz, tridymite, cristobalite, chalcedony, flint, opal, quartzite, White silica sand, diatomaceous earth, the silicon oxide (SiO2) contained in these siliceous materials is at least 90% . The silicon oxide in some pure raw material can be above 99 %. Siliceous materials are acidic in high-temperature chemokinesis. when existing metallic oxide or contact with metallic oxide, they will conduct chemical actions and conbine into fusible silicates. Therefore, if the siliceous raw material contains a small amount of metal oxide, its heat resistance will be seriously affected..
- Q: What are the differences between first-level fire-resistant materials and second-level fire-resistant materials?
- The combustion performance of materials could be divided into: A( noninflammability), B1(flame retardancy), B2(flammability), B3(inflammability). Building materials are divided into four ranks according to these properties. 1. In accordance with Code for Design of Building Fire Protection(GBJ16-1987)(revised edition in 2001), fire hazards in producing and storage can be divided into five types. In Fire Prevention Code of Petrol Chemical Enterprise Design(GB50160--1992)(revised edition in 1999), classification of fire hazards is also achieved according to the hazards of materials that have been using, producing and storing. Measures in prevention of fire explosion could be taken from the perspectives of fire separation, fire resistance level of structures, allowable floors, safe evacuation, and fire extinguishing facilities based on different levels of fire hazards. 2. Four fire resistance rating of buildings are listed in the book Code for Design of Building Fire Protection. And specific stipulations are made to the fire resistance of main elements of buildings, such as bearing walls, beams,pillars, and floors. When designing a building, if permitted, refractory materials of high-rank should be adopted in those buildings which have high potential fire hazard and a lot of combustible material and valuable equipment. While making sure fire resistance rating, the duration of fire resistance of each elements should meet its requirements.
- Q: How to divide fire resistant level of fire door?
- Fire resistant level of fire door【Class A fire door】. Class A fire door is also called complete fire door. It can meet the requirement of fireproof thermal insulation and refractory integrity at the same time in specified time. Fire resistant levels are 0.5h(Grade C), 1.0h(Grade B), 1.5h(Grade A) and 2.0h, 3.0h. 【Class B fire door】Class B fire door is also called part heat insulation fireproof door. Its requirement of fireproof and thermal insulation performance is 0.5h. Refractory integrity levels are 1.0h, 1.5h, 2.0h and 3.0h respectively. 【Class C fire door】Class C fire door is also called not thermal insulation fireproof door. Ther is no requirement of its fire resistance and thermal insulation. It only meets the requirement of refractory integrity in specified refractory time. The grading of refractory integrity is 1.0h, 1.5h, 2.0h and 3.0h respectively. There is the content of not thermal insulation fire door in British BS standard.
