Q:Who knows the fire rating of fire partition with steel stud?
Cement board wall of steel stud: it is used for walls with ceramic in kitchens, restroom, disinfect room, etc. If single-sided tile is made, cement pressure plate can be used on one side. Gypsum board is used on the other side. Fire rating is A1. CaSo4.2H2O is molecular structural formula of gypsum which contains 20% water, crystal water and free water. When 10% water slowly evaporates on the flame surface, there is still 10% crystal water. Itself is grade A fire retardant material. 1 hour. It is in line with the fireproof test standard of national building materials. It can reach up to 4 hours at most.
Q:what's the requirements of refractory for forge furnace?
accurate answers please refer to Current Situation and Development Trend of Refractory Material in Heating Furnace ,Quality Requirement of Modern Industrial Furnace Refractory Material(GB/T17638-1998) Standard,Furnace-constructing Technology, if you need the mail box, please senf e-mail to me, my QQ number: 249704548.
Q:Is it normal for caable fire resistant material to catch on fire?
Abnormal, preventive measures: 1 take fire preventive measures. Measures taken for fire retardant measures of cable: (1) seal closely with fire resistant materials holes ran by cables through walls, shafts to prevent the cable fire, high temperature gas diffusion and spread when cables are on fire. (2) to wrap the cable with the insulation refractory material, when the cable is surrounded with fire, warpped cable is insulated by the insulation material from fire, so it will not be burned. If the cable itself is on fire, fire will be extinguished thankes to lack of oxygen in warpped cable, to avoid the fire to spread out. 2 to strengthen the cable circuit switch and regular protective check and maintenance, to ensure that the action is reliable. 3 to strengthen the cable operation and monitoring, to avoid the overload of the cable operation. . 4 regularly clean dust on the cable, to prevent cable from catching on fire due to the accumulation of dust. 5 to ensure the construction quality, the quality the cable must be strictly in line with the requirements and standards. 6 cable laying should maintain enough distance form the heat pipe, control cable is no longer than 0.5 meters; power cable is no longer than l meters. Control cable and power cable should be divided into slots, be layered and seperated instead of being overlapped . For the parts that do not meet the requirements, measures must be taken to insulate heat and fire. 7 regularly teat cable , abnormal problem should be handled in a timely manner. 8 install fire alarm so that fire will be discovered on time, and cables will not catch on fire. 9 the cable trench should be kept dry to prevent the cable from being affected with damp, or leading to declined insulating function and short circuit.
Q:What are the structural properties of refractory materials provided by the manufacturer of the refractories include?
Metal oxides have very good resistance to high temperature, such as: three, two aluminum oxide, Magnesium Oxide...
Q:How long is the duration of fire resistance that fireproof window of level B can endure?
The duration of fire resistance: fireproof window of level A shall not be less than 1.5h, while level B shall not be less than 1.0h. The frame of both fire proof windows A and B are made of steel, and the glass, not less than 26mm, is composite insulation fireproof glass. Monolithic fireproof glass window is neither B fire proof window nor A fire proof window, but non insulated fire proof window.
Q:what grades are fire resistance of fireproofing glass divided into?
Fire resistance of fireproofing glass is generally divided into three levels, class A glass can satisfy the requirements of fire resistance and thermal insulation at the same time. Class B, it's a kind of fireproofing glass that can satisfy the requirements of fire resistance and heat radiation strength at the same time. Class C can satisfy the requirements of refractory integrity, if you want to know more specific requirements, you can also surf the internet for a more detailed description.
Q:who knows the technology of fireproofing material?
1, dealing mould, scrape and clean the thick liquid on the surface of mould with tin-coated steel scraper blade or plaster tool. 2, adjust laminator, according to the thickness of fireproof panel, adjust each roller, keep them parallel. 3, ingredient, according to the requirements of recipe, stir the raw materials uniform with agitator. (usually we should add bittern firstly, stir it with modifying agent for 5 minutes, then add filler and stir for 2-3 minutes, finally add grogs and stir it to uniform) note: the stirring speed should be kept in 60-80 r/min. 4, place the cloth, place a layer of non-woven fabric and two layers of glass fiber fabric (mechanical spread fabric). 5, flitch, place the materials after compounding and stirring into stop gauge of laminator, then you can start up and produce continuously, it's finished product after finishing. note: the distance between two templates is 2-4mm.
Q:The principle of choosing fire-resistant material in Thermal Energy and Power Engineering equipment.
What thermal equipment? The most simple principle is durable, low cost and with no environmental pollution.
Q:What are the fire resistances of grc partition panels?
waterproofing: It has good water resistance; 2. fireproofing: fire resistance of partition panel≥3.5h, it has an excellent fireproof performance and can be applied to fire-proof bulkhead; 3.soundproofing: According to the different thickness of walls and surface treatments, perlite light partition panels insulation can be 40-50 decibels, to ensure that products can be used for office, commercial, entertainment and residential buildings; 4, light weight:
Q:What thickness is needed of the ultra-thin fireproof paint with a fireproof time of 2.5 hours?
There are two kinds: 1, the thickness of the plate is between 20 ~ 50 mm with composite structure 2, sheet thickness is between 6 ~ 15 mm calcium silicate fire prevention board.
We has been adhering to scientific and technological innovation as the company development ideas, establishing the export-oriented development strategy and has close technical cooperation with scientific research institutions.We supply many kinds of calcined bauxite.
