Q:What kind of flexible fireproof material is really good?
Flexible waterproof materials mostly are asphalt, linoleum and other organic material, which is also called linoleum coiled material waterproof layer. it uses the linoleum, glass cloth fabric as tire layer coil, using all kinds of cementing material phase of asphalt and so on. Make coil bind on roof structure plate leveling layer to form waterproof layer. Flexible waterproof material has high tensile strength, big elongation and light quality, which is convenient to construct. But it has relatively strict operation technology can resistant penetration and aging resistance than rigid materials, aging. Its life is short. Refers to a kind of waterproof material form relative to the rigid waterproofing materials such as waterproof mortar and waterproof concrete. In the form of its and grassroots attached two categories, it includs waterproof coating and waterproofing materials. According to different paste position of waterproof material, it can be divided into outside waterproof waterproof (outsourcing) and inside waterproof (insourcing waterproof) two kinds. Waterproof coil material must be stuck in the grass-roots that have enough stiffness of the. Before pasting, you should apply leveling layer and waterproof layer should be added protective layer of the outside, and need to make the rotation of the flexible material, the processing of subsequent and head closing, in order to ensure the continuity of the waterproof layer and sealing. In addition, there are all kinds of waterproof material and moistureproof coating material.
Q:Who knows the classifications of magnesia refractory?
Magnesia chrome series products: The main ingredients of magnesium chromium series are MgO and Cr2O3. Periclase is the first phase and magnesia-chrome spinel is the second phase. Products belonging to this series are magnesium chrome brick and chrome magnesia brick. The main ingredients of magnesium aluminum series are MgO and Al203. As they generate MgO and Al203, all magnesium chromium series products contain magnesia material. magnesium calcium series products The main components are MgO and CaO. They have high melting points, which are important magnesia materials. 5, magnesium silicon series products: The main component of magnesite series is SiO2, when the C / S<5, SiO2 and MgO generate MgO.Al2O3 (forsterite). From the perspective of microscopic mineral, main products of pure aluminum series include magnesium aluminum brick, periclase spinel brick, corundum spinel brick and aluminum-spinel castable in unshaped materials. I hope this answer can help you.
Q:The fire prevention board line is made of what material?
(1) if it's real wood floor, the line should be made of wood. The ready-made wooden line, walnuts, price range depends on the texture width. The common width is 100 mm. One linear meter is around $17 - $30. Paulownia is cheaper with one linear meter more than 10 yuan. When it is composite wood floor, high-density plate modelling line can be used. The price is commonly between 40 to 80 yuan (2400 x 1200 mm), which depends on the thickness and density and also the factory. There are also imitated wooden aluminium line. (3) if it's the marble ground, you would better use marble line, which is 200 yuan one square meter. It's price is also unequal. The imitated stone is also available. There are a lot of kicking decoration materials and it depends on how you use it. That is to say crural line should be coordinate with the ground. It means that it sjould not only to be beautiful but also to be practical. It would be better if it is relatively cheap as well.
Q:What are the requirements of the performances of brasque refractory?
It is a kind of inorganic non-metallic material whose refractoriness is not lower than 1580 ℃. Refractoriness is the centigrade temperature of refractory cone specimen wiyhout any load resisting high temperatures without melting down But only refractoriness can not fully describe the refractories, 1580 ℃ is not absolute. Refractory is now defined as material of physical and chemical properties allowing to be used in high temperature environments. 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.
Q:Which kind of refractory does insulation board belong to ?
Q:What do RH and DH stand for in refractories?
DH :For human intelligence (diameter, board of directors). )
Q:Does refractory belong to metallurgical auxiliary materials?
Refractory is widely used in industrial circle, such as metallurgy, chemical industry, petroleum, mechanical manufacturing, silicate and power, and its coonsumption is the maximum in metallurgy, accounting for 50% to 60% in total output. In order to improve slag-corrosion resistance of furnace lining, usually choose carbon-containing refractory. Refractory of various furnace lining are respectively: For the body, it is clay brick; as for the lower part, bosh and middle, it is SiC brick; for furnace bottom, it is carbon brick. Lattice brick is an important refractory product used in air heating furnace and regenerative chamber. Refractory is widely used in metallurgy. In order to improve slag-corrosion resistance of lining. Central line in tuyere and hearth are high-alumina brick. Refractory consumption is the maximum in metallurgy, accounting for 50% to 60% in total output. For the bosh and middle, it is SiC brick. In order to improve its thermal storage capacity: The furnace stack is clay brick. It is defined as refractory where the physical and chemical properties allows its use in high temperature environments; The lower furnace body
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:What's the heat conductivity coefficient of fire-resistant material?
There are many types of fire-resistant materials woth different thermal conductivity. The question should be more specific.
Q:What is the the best matching ratio of refractory cement?
Refractory cement is very easy to use. Add some water and mix, and it will harden. Generally there is no need to add other binding agents, but you can add some refractory aggregate and powder. If you use only refractory cement, it will produce a lot of cracks after high temperature. Generally refractory cement can withstand temperature of about 1300 degrees. Refractory cement can be used together with ordinary sand, and the ratio of cement and the sand is about 30 percent.
