Q: What is unshaped refractory?: Concrete。 Early concrete technology appears, it is not forming products in the heat furnace, some parts such as pit heating furnace furnace wall, rotary kiln mouth ring, cutting slope and discharge chamber wall, etc., are able to design large masonry (top heating block weighing 3-4 tons) made concrete. Concrete cattle production method is to pour the material into the model, vibration molding, after the release of heat treatment, to provide users in addition to large blocks, weight, in use, and machine pressure brick no essential difference. The amount of water used in the casting material produced by the manufacturer is less than 10% above that in the field, and the processing quality is good and the quality is stable. As the bricks are large and heavy, the site shall have lifting equipment. As long as the site can be hoisted, the concrete shall be used as far as possible, or smaller ones, and some people can lift it. Concrete does not require the user to do a special heat treatment, this point is very meaningful.

Q: Can anyone say something about the curtain wall fire-proof material key sealing point?: Keypoints; 1, curtain wall design must consider the safety requirements, one of which is fire protection design. 2, Generally, fire protection planning between curtain walls should use the method of setting fireproof isolation layer. 3, Two layers of fireproof isolation layer whose thickness should not be less than 100mm respectively on the top edge and lower edge of the material parts of the house. 4, the fireproof isolation layer commonly uses 1.5mm thick galvanized steel sheet as supporting plate, using for shelving fireproof sheet. The 100mm thick cavity between the layers is filled with mineral wool non-combustible materials tightly covered with tinfoil on the surfaces. 5, protective isolation layer should try to reconcile curtain wall beam level and finish floor level, so as to fill non-combustible material and to avoid that a piece of glass acrosses two fire?compartments. 6, the beam should be inside 100mm thick fireproof isolation layer to protect the beam and the upper curtain wall plate. 7, when there are open fire function areas like large-scale hotel or restaurant kitchen inside the curtain walls, curtain wall glass in these parts should consider using cesium potassium fireproof glass to improve the fireproof rating in the region. 8, Fireproof setting in the around areas of curtain wall can use the same method of the above fireproof setting between layers. The joint parts of fireproof isolaton layer and main part as well as curtain wall should use fireproof sealant to seal.

Q: What are included in fireproofing materials?: There are many types of fireproof materials, and the following listed below is the main species: All kinds of fire retardant coating such as finishing fire retardant paint, fire retardant coating components, fire-resistant coating for steel structure; all kinds of fire-proof materials such as fire?retardant material and its products, textile, fire?retardant fabric, building materials and products, flooring material and external wall thermal insulation system; all kinds of fireproofing components such as fireproof?panel, fire door, fire resistant window frame, fire resisting shutter, fireproofing glass, elevator landing door,ventilating duct, fire-proof?sealing?material and fire protection smoke exhaust fan. The main indicators to judge fire resistance are: Flame retardency, ignition,production of?toxic?gases, smoke density,heat release and exhaust gas; fire resistance, combustion performance, heat of combustion, fire-resistant performance, high temperature resistance, fire?rating, etc. There are some specific parameters which need to be judged by a professional testing equipment. You can go to the inorganic laboratory to check. The test results of fire rating are accurate.

Q: What are grade classifications of the external walls for fireproofing?: 1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 Level A insulation material is only for fireproofing, but its thermal insulation performance is not better than organic XPS \\ EPS and other materials. I feel the best insulation materials should be modified phenolic board, which can keep insulation and fireproofing, but the comprehensive unit price is very expensive.

Q: What are the types of steel refractory materials: Large steel ladle usually made with magnesia carbon brick, of course, it contains a intermediate layer (such as good a little high alumina castable), heat insulation layer and heat preservative materials Alumina-magnesia castable is OK for small steel ladle

Q: What kinds of fireproof materials does the safe use?: The fireproof materials of safe, copper is one of the most widely used material of locks for its good mechanical performance, corrosion resistance and processibility and beautiful colors.

Q: how long is the fire endurance of plasterboard?: fireproof endurance can reach a maximum of 4hours, suitable for a variety of public buildings firewall, and partitions for public exit passageway, reaching standard level of fireproof. the lightweight partition made of gypsum board and steel stud is mainly for dividing architecture space. Rock wool can be filled in the mddle according to its design requirements, using different series of gypsum board, steel stud. the walls may have fire resistance and sound insulation property of various degrees.

Q: What are the requirements on fire resistance period of C-level fireproof glass?: Class C: The fireproof glass which only meets demand of fire integrity. This glass has advantages of transmittance, fireproofing, smoke resistance and high intensity. It can be applied to fireproof glass partition walls, fire windows and with no requirements on outdoor curtain walls, etc. The fireproof glass can be classified as composite fireproof glass and single chip fire-proof glass in terms of structure. Class B: The fireproof glass which meets demands of fire integrity and thermal radiation intensity at the same time. This glass is mostly composite fireproof glass which has advantages of transmittance, fireproofing, and smoke resistance.

Q: What are the new refractories?: There are many of them. We can talk face to face. Sichuan Province Deyang City Xinxin Refractories Co. 0838-2228543

Q: What needs to be paid attention to in the construction of high- temperature refractory mortar?: As far as I'm concerned, in the construction of high-temperature refractory mortar, these matters should be noted: 1. During the use of high-temperature daub masonry stove, the minimum mortar joint should be 0.5mm and general mortar joint should be 3-5mm, which can solve the processing and fine grinding of refractory brick on the brick grinder. Besides, it is conducive to the health of workers, and can reduce the masonry effort, ensure the quality and speed up the construction progress. 2. When making urgent repair on the stove, if the joint is much too large, 2-3mm refractory pieces can be appropriately added into the high- temperature refractory mortar, and stirred to fill the joint so as to shorten the repair time and ensure normal production. 3. High- temperature refractory mortar can be painted inside various furnace body, and it should be guaranteed that the surface of the furnace body has no dust or debris before painting.
