What is fused magnesite?
Fused magnesite is produced by high quality magnesite through electro- fusing, After melting, the SiO2 of material moves to the surface for the difference in the specific, so it has well grown crystals, well crystal perfection and structure homogeneity, excellent chemical stability, good corrosion resistance to slag and high strength at high temperature.
Where to apply fused magnesite?
It is widely used for gunning materials, fused magnesite ramming material, magnesite brick, magnesite chrome brick, vacuum and vacuum induction furnace, electric arc furnace refractory lining, magnesia crucible, furnace and a variety of refractory, such as large scale glass furnace by floating method, electrical furnace, convert furnace, house hold electrical appliances as electrical insulating materials,
- Q:What is fire retardant coating mainly used for?
- Fire retardant coating is a coating which is applied to the surface of buildings and structures and can form a protective layer of fire retardancy and thermal insulation. It can reduce the flammability of the coated materials and block the rapid spread of fire so as to improve fire endurance of the coated materials. Features of fire retardant coating: (1) Fire retardant coating itself has a flame-retardancy or non-inflammability, and it can prevent the protected substrate from direct contact with the air, and delay ignition and reduce the burning speed of the objects. (2) In addition to flame retardancy or non-inflammability, the fire retardant coating itself has a a low thermal conductivity, which can delay the transfer of flame temperature to the substrate to be protected. (3) When heating, fire retardant coating decomposes non-combustible inert gas to dilute the combustible gas decomposed by the protected, making it difficult to burn or slow down the burning rate. (4) Fire retardant coating containing nitrogen will decomposite NO, NH3 and other basic groups, which compound with the organic radicals and interrupt the chain reaction so as to reduce the temperature. (5) intumescent fire retardant coating will expand and foam when heating, and form a carbon foam insulation to block the protected objects, thus delaying the transmission of heat to the substrate.
- Q:What materials is silicious thermal insulation board made of?
- Refractories that contain more than 93% of the monox are acidic refractory materials which include ordinary silica brick, high-density and high-purity silica brick, silica brick that contains chromium, fused quartz products, unburned brick and siliceous ramming materials. It has good softening temperature under a fixed load and can resist corrosion of acid slag, but will have chemical reaction with alkaline slag. Silicious refractory of industrial value mainly is crystalline quartz, such as α and β quartz, tridymite and cristobalite.
- Q:What is the fireproofing requirements of external wall thermal insulation materials?
- According to the "building external wall insulation fire barrier zone technical regulations" to be published: it is not less than the level B2. But before the procedure was published, it should be strictly implemented the document, level A is the best, I hope to help you, hope to adopt
- Q:Who know what kind of fire shutter fire rating are there?
- There is no national standard for fire protection performance of fire roller shutter in China, and now the executive standard of GB14102-2005 "fire shutter": F1, fire-resistant time 1.50h; F2, fire-resistant time 2.00h; F3, fire-resistant time 3.00h; F4, fire-resistant time was 4.00h before the national standards of fire shutter grading is introduced, expert advice that fire resistance test be made according to national standard, to reach back fire surface temperature rise requirements, if the refractory limit is greater than or equal to 3.0h, it is said to be super fire shutter, if test not inspect unexposed surface temperature rise as a judgement of the conditions, the door is referred to as ordinary fire shutter doors. I hope my answer can help you
- Q:What kind of refractory materials are used in the intermediate frequency furnace?The domestic boric acid can be used as a lining?, how much is the rate?
- The variety of refractory materials for intermediate frequency furnace is mainly made of aluminum and silicon, both shaped and unshaped refractory materials are available. I have no ideas what you said boric acid, I’ve never seen that boric acid was used as an additive.
- Q:What's the refractory material?
- According to the product shape, it can be divided into two kinds, that is shaped refractory and unshaped refractory. According to the chemical?property, it can be classified into three categories, that is acid refractory, neutral refractory and basic refractory, among which basic refractory and neutral refractory are commonly used, such as the basic refractory of magnesia carbon brick, fired magnesite brick, magnesite-chrome brick, magnesia-calcium brick, and the neutral refractory of high alumina brick, corundum brick, clay brick. Unshaped refractory includes: castable, ramming mass, gunning mix, coating material, dry vibration material, etc.!
- Q:The difference between refractory and thermal insulation material
- In simple terms, refractoriness is different. The refractoriness of refractory is high while that of insulation material is low.
- Q:Does the aluminum silicate fiber can be used outdoors? If not, what other refractories can be used outdoors?
- Q:What are the raw materials of refractory? And what are their names?
- Q:Does anyone know the characteristics of refractory for glass kiln?
- Refractory is a kind of non-metallic material with refractoriness not less than 1580 ℃, which has better thermal shock resistance and chemical erosion resistance, low heat conductivity coefficient and low expansion coefficient. Refractoriness is the centigrade?temperature of refractory cone specimen wiyhout any load resisting high temperatures without melting down Refractory is widely used in industries like metallurgy, chemical, petroleum, machinery manufacturing, silicates, power, etc., which is mostly used in the metallurgical industry, accounting for 50% to 60% of total output.
