- Q:How to hang the suspended brick in the refractory masonry?
- First you can fasten the girder and the suspended brick with screws, and then move them to the specified location by a crane. You can contact the refractory plant in Shanshan mountain, Ningxiang Countym, Hunan Province at 0731-7150098.
- Q:What materials is silicious thermal insulation board made of?
- Siliceous insulating panels use quartz sand as the main material and are composited with fiber. Of course the amount of insulation board materials used by different companies is different. In terms of Hua Heng, siliceous insulating boards can be divided into insulating panels for casting slabs and insulation board for intermediate tank according to the usage. The latter one can be divided into liner plate (wallboard, side panels, baseboard) and impingement plate based on parts it is used on. Siliceous insulating panels use quartz sand as the main material and are composited with fiber. Method for manufacturing a silicon insulating panel is divided into semi-dry method and wet method. It is used for casting ingot insulation cap of the killed steel and continuous casting tundish.
- Q:which kind of fire?bulkhead is better?
- Fire bulkhead also known as non-combustible fire retardance board, and it's made by various incombustible?material after the scientific pressing, and has good flame resisting properties, it's non-combustible time can reach over 3 hours, high mechanical strength,it has characteristics of non-explosive, water and oil resistance, good chemical corrosion resistance and non-toxic. As for the combustion test of YD-Ba-type inorganic fire?bulkhead, it's best to be deformation under the flame temperature of 1000 ℃, the indicators comply requirements of GA161-1997, combustion performance reaches A level standards of GB8624(non-flammable). J fire bulkhead is mainly applicable to the fireproofing protection and fireproofing isolation of cables with all kinds of voltage?classes laid on scaffold or bridge. It's widely used in cable project fireproofing and fire?retardant in the places with crowded cables, such as various power plants, chemical companys, iron and steel smelting enterprises, mines,etc. It's also the best fireproofing and fire?retardant materials of fireproofing and fire?retardant projects in indoor decoration of public places, such as large shopping malls, hotels, guesthouses, sports hall, closed clothing market, light industrial markets, theaters and so on. Construction method: Fire?bulkhead products can be cut by saw, according to the shape required to be made in the construction site, using steel brackets or expaned anchor bolt to fix it while assembling, steel brackets should be coated with fire-resistant coating for steel structure. You can also use various cable and fireproofing trays made of fire bulkhead, and used in the board gaps.
- Q:How can the furnace be replaced after the gasifier or water wall is replaced with refractory material?
- If there is only a small local, bake according to the overall it is really troublesome, water wall repair point of direct drive estimation problem is not large, the water wall itself is used to slag slag slag principle, can also play the role of refractory materials.
- Q:I know which material is the fire resistance rolling shutter door
- the materials of fire resistance rolling shutter door are: the inner of fire resistance rolling shutter door is generally filled with aluminum silicate fiber cotton. fire resistance rolling shutter door is divided into AAA inorganic fireproof rolling shutter door and steel fire resistance rolling shutter door. the fireproof?performance of inorganic fireproof rolling shutter door is better, but steel fire resistance rolling shutter door has a certain wind load resistance, which can be installed outdoors.
- Q:How to classify the grade of wall fireproof and thermal inuslation matertial?
- External wall thermal insulation materials are mainly divided into grade A, grade B1, grade B2 and grade B3. In accordance with the current "Combustion Performance Classification Method of Building Materials", grade A thermal insulation material is incombustible?material and belongs to inorganic heat preservation material. However, grade A thermal insulation material is few in terms of the current market. There are only JETCO YT inorganic active wall thermal insulation material, glass wool, rock wool board, foam glass, vitrified micro bead and grade A fireproofing thermal insulation board. However, compared with grade A thermal insulation material, the more welcomed by the market is the organic insulation materials. Thermal insulation material that is determined as grade B is divided into three levels. Grade B1 is grade is flame retardant. Grade B2 is combustible. Grade B3 is flammable.
- Q:what grades are fire resistance of fireproofing glass divided into?
- Fireproofing glass is a kind of special glass which can keep its integrity and thermal insulation performance in regular insulating refractory trials. and it can be divided into three classes according to its fire resistance: Class A, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. This kind of glass has the properiyies of transmittance, fireproofing ( smoke insulation, fireproofing, and keeping out thermal radiation), sound insulation, shock resistance, and it's suitable for steel and wooden fire door of building decoration, windows, varnishing, partition walldaylighting?roof,ceiling?screen,perspective floor and other construction components demading for transparency and fireproofing. Class B, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. Such kind of fireproofing glasses mostly are composite fireproofing glasses and has characteristics of transmittance,fireproofing and smoke insulation. Class C, it's a kind of fireproofing glass that only satisfies the requirements of refractory integrity. This kind of glass has characteristics of transmittance, fireproofing, smoke insulation and high strength,etc. It's suitable for fireproofing glass partition wall, fire Windows, outside curtain wall and other places without insulation requirements.
- Q:Who can introduce the difference between galvanized fireproof?coatings and steel structure fireproof materials?
- There is no difference between them because they are the coating with the same texture. But generally galvanized treatment is not necessarily needed for brushing fireproof coating. Fireproof coating and galvanized surface have relatively poor bond strength. So it is advisable to bursh trasitional lacquer or micaceous iron on galvanized surface.
- Q:What is the importance of silicon powder in refractory processing?
- it can certainly improve the fire resistance
