Q: How to use fire-resistant soil?: Clay refractory soil 1, characteristics and uses: Clay refractory brick is a weak acid refractory material, its thermal stability is good, suitable for hot air furnace, all kinds of boiler lining, and flue, smoke room, etc.. 2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.

Q: What's the fire endurance of fire windows?: Fire endurance of fire windows: A class fire window: no less than 1.2h; B class fire window: no less than 0.9h; C class fire window: no less than 0.6h. Technical requirements: 1. Materials and fittings: (1) Window frame should adopt the steel frame or wood frame with certain strength so as to guarantee the integrality and stability of the fitting; (2) Steel frame and mound layer can choose the galvanized steel sheet or stainless steel sheet. Its selection standard is in line with provisions of Article 5.1 in GB12955 "General Technical Requirements on Steel Fire Doors"; (3) Selection standard of wood frame and mound layer should be consistent with the provisions of Article 5.1.1 in GB14101 "General Technical Requirements on Wood Fire Doors"; (4) Filler material inside the steel frame and wood frame should be incombustible material; (5) Fireproof glass can choose the qualified product with no influence on the fire resistance test of the fire window, and its light transmittance should be no less than 75% of that of the ordinary sheet glass with the same layers; (6) Sealing material between the frame and the fireproof glass should use flame retardant material which can play the role of fire prevention and smoke control in the case of fire. (7) Hardware fittings should be approved supporting products which is detection qualified.

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 roof thermal insulation fireproofing material?: Aluminium foil, bubble, aluminium foil/air bubbles/fireproofing aluminium foil thermal insulation material, fireproofing bubble thermal insulation material, fire?retardant thermal insulation material, thermal insulation construction materials, aluminum foil insulation material.

Q: Which industry does the metallurgy and thermal insulating and refractory material belong to?: Materials Industry

Q: what kind of fireproof materials is used for high rise buildings?: First, fire resistance steel door: in the general real estate, developer uses more of fire resistance steel door. The mid-low-end doors are the earliest products and mostly widely used with longer servce time. The disadvantages are corrosions, thus it will rust, fade after being used for a while, and will affect the overall appearance. Styling lines are hard, not matching well with modern home decorative styles. Second, the stainless steel fire doors: anti-theft performance ,durable, stronger security. Compared to the general iron or mixed iron and steel security doors, stainless steel doors never rust and most importantly its uniqueness in addition to lasting bright color. Disadvantages: Stainless steel security doors are mostly silver, giving us dull feelings by seeing its appearance and color, lack of coordination. Third, glass fire door: high quality fire glass doors. recent years have seen wide application in office buildings and some high end public place, less in individual users. Compared to the current categories of timber, fire glass door is not only simple and luxury and durable.

Q: What is refractory?: Refractory materials are widely used in metallurgy, machinery manufacturing, chemical industry, petroleum, power and other industrial fields. It is an inorganic nonmetallic material mostly used in metallurgical industry with the minimum refractoriness of 1580 ℃, able to resist high temperature without softening (annealing). It accounts for 50% to 60% in total output. Refractoriness refers to refractory's ability to resist fire.

Q: What needs to be paid attention to in the construction of high- temperature refractory mortar?: In the construction of high-temperature refractory mortar, the following matters should be noted: 1. Take out the organic fire blocking material and knead it into tha shape of a ball. If the temperature is too low, the blocking material along with the package can be put into 40-70℃ warm water and heated before any other operation. 2. 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. 3. 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. 4. 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. The holes should be cleaned up before plugging. Lay, embed, and fill the blocking material into the gap of holes evenly. For larger holes, flame screen can be used as the framework to increase strength.
