We make graphite parts from top grade graphite material. The finish part has excellent mechanical property. With the high compressive strenggh and high thermal shock and corrosion resistance,the usage loss is very low. It can save both your time and money.

Q: How many kinds of A-level fireproof and thermal insulation materials are there?: Please give us some information about the kinds of A-level fireproof and thermal insulation materials in the market.

Q: Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?: Strictly speaking, as long as there are solid wood packaging, you need to do fumigation inspection, proved not necessarily used, there are IPPC chapters on it.

Q: What's the function of aluminium dihydrogen phosphate on the refractories?: Mainly used for binder of high-temperature furnace refractory. Characteristics of liquid aluminum dihydrogen phosphate, castable. solid used for refractory spraying coating, chamotte, ceramic construction, which has high break resistance after being dried in 350-500 ° C, phosphate bricks. Characteristics of the solid aluminum dihydrogen phosphate, binding agent used for castable and casting industry: together with the refractory aggregate, ramming mixes at room temperature: Easy to mix, crush resistance, hydration resistance, chamotte, will not become soft even if soaked or boiling in water, molding. Liquid use refractory spraying coating, mainly used for corundum, chrome corundum water gap in refractory industry. The production of chrome aluminum zirconium corundum brick for water-coal-slurry gasifier is especially suitable for site construction applications mainly used for the electrical industry, high-temperature kiln and furnace, hardener, after mixing between 90-110 ° C for 4-24 hours at a constant temperature, forming strong bonding strength, electrical insulation, heat treatment resistance furnace

Q: What are the new refractories? What are the features? How about their application and development?: In metallurgy, in what position should it be used, in order to make the best. Answers are as following. In iron, steelmaking or converter. When questioning, pay attention to the ways. Answers: Try to use synthetic refractory materials.

Q: What's the definition of fire endurance of the fire-resistant coating for steel structure?: 1. Fire endurance. Conduct fire resistance test of any building component according to the standard time-temperature curve, and the time when it is subjected to the fire to the time when it loses support capability or fire insulation function or its integrality is destroyed is referred to fire endurance. 2. Steel has relatively low fire endurance which is usually 0.25h only, namely 15 minutes; 3. Of steel structure buildings, steel can be used as beams, pillars, etc. but its fire endurance is not enough (usually these components have higher requirement on fire endurance, and take pillar as an example, it is usually demanded that the fire endurance should be 2-3h), and under this condition, it needs to brush fire retardant coating so as to raise the fire endurance. As to the specific quantity or types of the fire retardant coating, it is decided upon the actual conditions. In short, the building material needs to meet the required fire endurance of the buildings.

Q: what is the specs of thermal insulation refractory slab ?: According to different requirements of each project to select the fire board. fireproof?panel should have product qualification certificate. Specifications shall comply with the requirements of design drawings and inspection reports from the National Fireproofing Protection Building Materials Inspection Center. General specifications are as follows: Length: it is determined according to the project width: 1200mm, 900mm; thickness: 9.5mm, 12mm, 15mm, 18mm, 25mm. Commonly used is 12mm. According to different requirements of each project to select the fire board. Fireproof?panel should have product qualification certificate. Specifications shall comply with the requirements of design drawings and inspection reports from the National Fireproofing Protection Building Materials Inspection Center. General specifications are as follows: Length: It is determined according to the project width: 1200mm, 900mm; thickness: 9.5mm, 12mm, 15mm, 18mm, 25mm. Commonly used is 12mm.

Q: Who can tell somthing about how to choose fire resistant rating of fire resistance rolling shutter doors?: There is no necessary connection between them. Different fire resistant ratings of bulidings require different fire endurance of different elemements of buildings. According to the fire endurance, fireproof doors can be divided into A-grade, B-grade and C-grade, whose fire endurance should not be less 1.2h, 0.9h and 0.6h respectively. A-grade fireproof doors can be even applied to the material whose fire resistant rating is at secondary level. "Building Regulations" mention that fire resisting shutter can be used as partition of fire?compartment in those places where setting firewalls is not so easy. When using fire resisting shutter whose fire endurance doesn't include unexposed surface temperature rise, it should install closed independent automatic sprinkler system for protection on both sides, and the sprinkler sholud last at least 3 hours.

Q: Who knows the texture of fire-proof wooden door material?: Steel door, wooden door or steel wooden door can be inset fireproof laminboard, such as rock wool, perlite. Perlite (fireproof doors filling material, fireproof doors raw material) using for fireproof door core is mainly used for the filling material of fireproof doors and security doors. Fire protection, thermal insulation, good sound insulation effects, and higher performance than aluminum?silicate?wool and rock wool. The combustion performance of perlite using for fireproof door core reaches class A non-combustion, which is new type of fireproof doors filling material with characteristics of low cost, good fireproof performance and excellent environmental protection performance. The advantages of fireproof door core perlite as fireproof door filling material: 1, Good fireproof performance, so it has a function of fire prevention. Environmental protection: all materials are environmentally friendly products. Pollution-free: the product is composed of glass fiber reinforced materials and inorganic binder. 2, with characteristics of non-flammable, non-explosive, water-resistant, oil-resistant, chemical erosion resistant, non-toxic and good mechanical strength, etc. The product can be used for mechanic processing like sawing, drilling, gouging, etc. High fire resistance, in the simulated combustion tests, it doesn't deform when the flame temperature reaching 800 degrees, has good fire retardant and fire-resistant properties. 3, product material is cheap, suitable for all kinds of fireproof materials. Perlite fireproof board is made by pressing the expanded perlite powder and high temperature fireproof adhesive through mould, suitable for the filling material of fireproof wooden door and fireproof steel door, which is the substitute products of aluminum?silicate?wool and rock wool. 4, has advantages of light volume-weight, high refractoriness, strong compressive strength, small thermal conductivity, non-flammable, non-toxic, tasteless, non-pollution, etc.

Q: Refractory inquiries: Special refractories are new inorganic non-metallic materials developed on the basis of traditional ceramics and refractory materials.
