Q: what's the varieties of fire-proof?sealing?material?: ATD-AB, organic fire-proof caulking, fire retardant bag, fire retardant net, fire retardant ring, fire barrier wrap, fireproofing sealing strip, flexibility fireproofing coiled material, fireproof glue, etc., fireproofing sealing materials currently on the market can be divided into two types, one is the traditional type: flexible organic caulking, WXY-II, fire retardant bag, fire?bulkhead, cable refractory coating; there are some new materials used in large-scale projects: fireproofing coating board system (fireproofing coating board, intumescent fireproof sealing tape, elastic fireproof sealant, Waterborne Fire-retardant Coating), fire retardant module system (fire retardant module, sealing gum, cable refractory coating), fireproofing plaster system (fireproofing plaster, sealing gum, cable refractory coating).

Q: Which refractory quality inspection authority is good?: National testing agencies include National Refractory Inspection Center (i.e. LIRR), China Building Materials Academy (Guanzhuang, Beijing), National Center for Ceramic and Refractory Materials Inspection (Shandong) and China Metallurgical Research Institute (Beijing).

Q: What are the features of construction class A fire resistant door ?: 1, Save space and reduce cost. Feature of Nanjing Cathay Class A external wall thermal insulation materials : the thickness is between 60mm--180mm, so compared with the traditional block thickness, it saves architectural space greatly. At the same time, the weight is only 1/10 of that of the traditional wall, thus reducing coast in terms of architectural?structure. 2, Fireproof and green. Features of Nanjing Cathay class A fireproof external wall thermal insulation materials: fire endurance under high temperature of 1000℃ is 4 hours, and non-combustible performance can reach state A level, without any toxic gas in full compliance with international environmental standards. 3, Waterproof. Features of Nanjing Cathay Class A fireproof external wall thermal insulation materials: no slightest leakage when it is being used in containers for water without any waterproof finishing. It can be used in kitchens, bathrooms, basements and other wet areas. 4, Sound insulation. Features of Nanjing Cathay class A fireproof external wall thermal insulation materials: internal materials and EPS polystyrene foam granule have good properties of sound insulation and sound absorption. 90mm-thick wall can insulate 40dB sound, in line with national standard of sound insulation for residential building. 5, Thermal insulation. Features of Nanjing Cathay Class A fireproof external wall thermal insulation materials: main raw material is frezing resistant and thermal insulating material which is environmentally friendly and energy saving. With good effect of thermal insulation, it can keep indoor temperature at a constant level, so as to make the environment more comfortable.

Q: The development prospect of fire-resistant material: I also want to know, who can say, thanks all the way.

Q: What refractory material does cupola lining use?: In order to improve the service life of the lower wall and the bottom leather, dense and high alumina brick can be used for masonry. The front furnace is composed of the bottom, the wall and the top. The top of the furnace is vaulted or hanging flat roof. The front furnace body is usually made of clay brick and high alumina brick, and the bottom work floor is rammed with ramming material. The material is the same as that of cupola furnace. The bridge and the front guard taphole, slag hole and other parts due to erosion by high temperature molten iron and slag erosion, lower service life, frequent repairs. Large blast furnace adopts hot blast or oxygen enriched blast, which has higher temperature and higher production capacity... The damage is faster, and it is hard to maintain production by using clay brick or high alumina brick. Should be used aluminum, carbon or corundum refractory silicon carbide castables pouring or tamping, so that the integrity of good, high strength, corrosion resistance, and therefore significantly improved service life, generally up to one year or so. Refractory materials, including chimneys and spark traps, are used in other parts of the cupola. The chimney and the cupola shaft directly connected with the shell made of steel plate, lined with ordinary clay brick, can also be used ordinary refractory castable pouring. The chimney is provided with a furnace heat exchanger, which can preheat the air to 300~500 DEG C, and the spark collector is used for catching the hot coke and dust particles brought out in the flue gas. The chimney at the top of the reflector (cover) by plate welding, can also be used to cast iron, its lining refractory coating or spraying paint.

Q: What are the raw materials of refractory?: Refractory is mainly resistant to high temperature and fire. Sic refractories are widely used in refractory. I hope my answer will be helpful to you.

Q: Who knows the external wall thermal insulation materials fire rating requirements?: The basic requirements of ratings. The design should comply with relevant state regulations and standards, the combustion performance used in exterior insulation material shouls be level A and not less than the level B2 fireproofing material. The requirements of Department of Housing and the Ministry of Public Security No. 46: Residential buildings: the height of building is greater than 100 meters, the combustion performance of insulation materials should be level A. The other civil buildings: 24≤ height

Q: Firing high temperature kiln of refractory and internal temperature being as high as 1600 ℃, metal heat exchanger can't use, how to do?: Directly using silicon molybdenum kiln, the temperature is better. Now using the electricity is cheaper than the price of other fuels.

Q: Fire insulation and fireproof insulation board materials What is the difference in performance?: Fireproof Materials prevents burning through insulating while others by chemical reactions. The overall heat conductivity coefficient of Insulation materials are generally lowered by thermal conductivity of the material itself and the structure of it. Inorganic active insulation material uses ordinary cement, insulation stone, calcium powder, Platycodon grandiflorum as the main raw material.

Q: How many levels are there in the classification of PP fireproof materials?: PP fireproof materials level V-0: After two 10-second fame tests on the sample, the flame extinguishes within 30 seconds. Inflamer can not drop. V-1: After two 10-second flame tests on the sample, the flame extinguishes within 60 seconds. Inflamer can not drop. V-2: After two 10-second flame tests on the sample, the flame extinguishes within 60 seconds. Inflamer can drop.
