- Q: What's the feature of construction external wall fireproof and thermal inuslation matertial?
- It has properties of low heat conductivity coefficient, low density, high flexibility, fireproof and waterproof. Its heat conductivity coefficient at normal temperature is 0.018W / (K · m) . The thermal insulation property is three to eight times that of the traditional materials. And it is completely waterproof. [2] Thermal insulation lining has properties of low heat conductivity coefficient, low density, high flexibility, fireproof and waterproof. Light, generally about10-96kg / m3, 20kg / m3 or less is felt, 24-48kg / m3 is middle-hard plate, 48-96kg / m3 is hard plate, wherein 48kg / m? can be used as ceiling, with softening point being 500 ° C , thermal insulation 300 ° C. It is widely used in the United States, k =0.9. Calcium silicate thermal insulation product is developed in 1970s in China. With high compressive?strength, low heat conductivity coefficient, recycle and easily construction, it is widely used in the power system. In China, small workshop?production were the most common, then four production lines were gradually introduced from America, including instant fiber forming, dry method punched felt, which are advanced and quality, temperature endurance up to 800-1250 ° C.
- Q: I wanna ask you, which level is b1 fireproof and thermal inuslation matertial ??
- which level is b1 fireproof and thermal inuslation matertial: I soppose you mean rubber and plastic! Only rubber and plastic has b1b2 level. Level b1 is the fireproofing level b1, because the rubber and plastic does not belong to the fireproofing material. It only has fire?retardant. The wholesale of all kinds of thermal insulation material and construction needs to look at the name.
- Q: What are the chemical composition of refractory cement?
- Calcium aluminate prepared by calcining as the main component. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. Refractory cement is also known as aluminate cement.
- Q: What kind of refractories do the anode baking furnace use?
- Use refractory bricks.
- Q: What are the differences between intensive refractory busway and other busways?
- Compact busway is named after its structure, especially referring to busway which is closely laminated between phases and between phase and shell and use thin insulating material to achieve the insulation result. Fire-resistant busway is named after its uses, just as its name implies, for higher fire safety requirements need busway of higher fire resistance level. The structural style of fire-resistant busway can be intensive and of air type, depending on what material it use to resist fire, so there is no direct link between them, but there is a included relationship.
- Q: What kind of foundry ingot refractory materials are there? Please be more detailed.
- This question is a little bit extensive, because there are too much foundry ingot refractory materials.
- Q: Which region use more refractory?
- Places with steel mill, such as Hebei Province, Anshan City of Liaoning Province, south of Wuhan, Shanghai, all of these places have steel mills where use various types of refractories. In addition, architectural material industry, such as cement plant and glass plant all use refractories, but the variety is single, with a large amount.
- Q: how long is the fire endurance of plasterboard?
- Plasterboard is non-flammable B1 level products. There are introductions in Fireproof Specification of National Standard Building Interior Decoration Design. Plaster board mounted on steel stud can be used as A level decoration materials. In accordance with the national fire safety rules on fire durance of walls and ceilings and other components, we can not simply say whether a piece of gypsum board can meet the requirements. In GB "gypsum board" it clearly states: Fireproof plasterboard can endure fire longer than 20minutes. Wherein Dragon brand fire-resistant gypsum board can endure fire longer than 40 mintues. Gypsum board is comprised of dry wall, steel stud and various auxiliary materials. the fireproof performance of the gypsum board system is relevant to the type, quality , layers of the gypsum board, quality of keel and installations, whether the rock wool is filled and its unit weight, the treatment of seaming and some minor joints.
- Q: What are the additives and recipes of refractory?
- Trimeric major role played bulk water reduction effect can be considered strong trimer strong bleeding effect'm sure Hey lignin sulfonate water-reducing effect of the strong retarding superplasticizer effect in two critical recommendations with more money to buy homes are equipped who is willing to disclose ah experiments to solve the problem through Chuk Wan
- Q: What is the the best ratio of mortar in refractory cement?
- The ratio of refractory cement are: M10 the ratio of cement and mortar: cement: Sand= 346kg: 1631kg M7.5 ratio of cement and mortar: cement: Sand =274kg: 1631kg M5 The mix proportion of cement and mortar: cement: Sand = 209kg: 1631kg M10 mix proportion of composite mortar: cement: Sand: Lime =306kg: 1600kg: 29kg M7.5 mix proportion of composite mortar: cement: Sand: Lime =216kg: 1600kg: 64kg M5 The mix proportion of composite mortar: cement: Sand: Lime =205kg: 1600kg: 100kg
