Sound insulation; 5. Thermal insulation; 6. Install easily and shorten the construction period; 7. High safety performance.

Q:what's the classification of fireproof and thermal inuslation matertial?: 1. thermal insulation material with A class combustion performance. Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite (2) thermal insulation material with B class combustion performance: extruded polystyrene board after special processing (XPS)/ polyurethane after special processing (PU) , phenolic aldehyde, gelatine powder polyphenyl granule. 3,thermal insulation material with B2 class combustion performance: molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane (PU), polyethylene (PE),etc. sea capacity module and vitrified micro bead(cooperate with the innovator of vitrified micro bead, Liu Weihua) fireproofing issues have been completely solved.

Q:What are the requirements for fire?rating of construction suspended ceiling material ?: According to No. 42 ducument of department of housing construction and Ministry of Public Security: fire?rating of building suspended ceiling material should reach A level. Other civil buildings: Class A fireproofing material MCM should be set in buildings whose height is above 50 meters. National A level fireproof flexible?material is made up of soil, rock flour, sand, cement and other inorganic powder and modifying agent. Product density is 2327kg / m3. Upon examination, the combustion performance of the product meets A level requirements, and the additional classification meets s2, d0, t0 requirements. According to GB 8624-2006 sepcification, combustion performance of the product should reach A2-s2, d0, t0 level. Light, thin: 2-4mm thick / piece, saving space and cement, convenient to transport. : State Class A fireproof flexible?material. Freezing-thaw resistance: up to 100 freezing-thaw experiments (close to 100 years), the surface has no powder, no crack and no peeling. Aging and acid resistance: anti-aging property can reach more than 3500h, that is, it will not degenerate for 50 years. Recyclable: new energy, renewable , no "three wastes" emission

Q:Is there vermiculite in refractory?: Paint, small thermal conductivity, chemical, shipbuilding and other industries. Expanded vermiculite has excellent electrical?insulating?property, and it is stratified structure. It is a good thermal insulation material used in growing seedings, flowers and trees, bulidings, rubber and smelting. I hope my answer will make you satisfied. Refractory contains crystal water and board between its layers. For example, the interlayer of fireproof door contains expanded vermiculite, and after expansion, its specific gravity is 60-180kg& # 47. Electric insulation material. Expanded vermiculite is widely used for thermal?insulation?material and sealing material. Of course, some refractory also uses vermiculite; fireproofing material. Vermiculite is a good refractory material, whose maximum using temperature and unit weight can be repsectively up to 1,100 ℃ and 50-200kg/m3. When it is expanded, it is called expanded vermiculite. It is highly thermal insulated. Hard water softeners and paint. After unripe flake vermiculite is roasted in high temperature, its volume will expand 6- 20 times quickly. Friction materials, its volume can be quickly expanded several times to dozens of times. In addition. Quality expanded vermiculite

Q:How can the furnace be replaced after the gasifier or water wall is replaced with refractory material?: The furnace shall be made according to the type of refractory and the moisture content and the type of bond. Pay special attention to the discharge of free water and crystalline water, not too fast to prevent cracks!

Q:Refractory material, refractory brick: 1, according to the degree of refractoriness:Ordinary refractory material: 1580 ~ 1770 DEG CAdvanced refractory material: 1770 ~ 2000 DEG CSuperfine refractory material: >2000 DEG C2, depending on the shape and size of the product:Standard type: 230mm * 113mm * 65mm;No more than 4 measurements, (size ratio) Max:Min<4:1;Profile: no more than 2 concave, (size ratio) Max:Min<6:1;Or an acute angle of 50~70 degrees;Specific type: (size ratio) Max:Min<8:1;Or not more than 4 or a sharp angle; 30 ~ 50 degrees;Special products: crucibles, vessels, tubes, etc.3, according to manufacturing methods, refractory materials can be divided into:Fired products, unfired products, unshaped refractories4. classification according to the chemical properties of materials:Acid refractory material, neutral refractory material, basic refractory material

Q:What are the differences between intensive refractory busway and other busways?: Compact busway is named according to its structure, and fire-resistant busway is named after its uses. Compact busway especially refers to busway which is closely laminated between phases and between phase and shell, and use thin insulating material to achieve the insulation result. suitable for power supply system of alternating current three-phase four-wire, three-phase five-wire system, frequency of 50 ~ 60Hz, rated voltage up to 690V, rated operational current of 250 ~ 5000A, as auxiliary equipment for mining, enterprises and high-rise buildings, and especially suitable for the transformation of workshop and old enterprises. Fire-resistant busway is composed of shell coated with fire retardant paint, bus line wrapped with fire-resistant mica tape and bracket made by refractory insulating material. Bracket has a plurality of grooves where inbedding the bus line and fixed it. There is a busway connecting box at one end of the busway and there is a bus line splitter box in the busway. Fire-resistant busway has excellent insulation properties, which can not only be used continuously in a normal environment, but also can be used in the fire environment continuously for more than one hour, suitable for high-rise buildings and important facilities, replacing the fire-resistant cables to transmit and distribute power .

Q:How many fire endurance grades are the AAA fire resisting shutter divided?: The different fire resistant levels of the building have different requirements of the fire endurance of the building component. According to the fire endurance, the fire doors can be divided into Class A, Class B and Class C fire doors with the fire resistances are not less than 1.20h, 0.90h and 0.60h. Even the fire resistant level of B can also use the first rate fire resistant door.

Q:What are the requirements of refractory temperature of refractory brick?: Refractory bricks furnace pipe material is generally divided into two types, namely, shapeless refractory material and shaped refractory. Shapeless refractory material, also known as castable refractory, is hybrid powder material made up of many kinds of aggregate or aggregate and a kind of or many kinds of binders. It must cooperate and evenly stir with a kind or many kinds of liquids during use and has strong mobility. Shaped refractory material usually refers to refractory brick whose shape has standard rules. It can also be processed temporarily during cutting according to requirement. Refractory brick, called refractory brick for short, is refractory material made by firing refractory clay or other refractory raw materials. Faint yellow or brownish, it is mainly used in building smelting furnace. It can resist 1,580 ℃-1,770 ℃ high temperature.
