Q:What are the applications of refractory busway?
Fire-resistant busway has excellent insulation property, and it can not only be used continuously in a normal environment, but also be used continuously when catching fire for more than one hour. It can be used in high buildings and important facilities in replace of fire-resistant cables to transmit and distribute electricity.
Q:How many kinds of A-level fireproof and thermal insulation materials are there?
Shenyang polystyrene board, extruded sheet, polystyrene particles, and polystyrene plastic plates...
Q:Refractory material, refractory brick
Refractory materials of various varieties, different uses, it is necessary to scientifically classify refractory materials, so as to facilitate scientific research, rational selection and management. There are many classification methods for refractory materials, among which chemical properties classification method, chemical mineral classification method, production technology classification method, material form classification method and so on are included.
Q:What antioxidant will be used in refractories?
Specifically speaking, it is an antioxidant used in carbon refractory products, which belongs to the fire resistant technology. A kind of refractory used antioxidants, formula proportion is as follows calculated by weight percentage: aluminium zinc alloy 1 ~ 100, conventional antioxidants in 0 ~ 100. Described in the aluminum zinc alloy element of aluminum content is 3% ~ 3%, the rest is zinc. Described aluminium zinc alloy is powder or fibrous long; The biggest size and long fiber powder makeup of maximum diameter is 0.2 mm. Preparation of the present invention contains aluminum zinc alloy antioxidants can prevent carbon oxidation temperature range is big, less side effects, and can adjust the thermal expansion of refractory. Hope I can help you.
Q:How is refractory material made?
It is made from yellow mud and water.
Q:What is the main material of fireproof wooden door?
Fireproof wooden door has a lot of materials! including imported timber decorative effects: utilizing the diversity and easiness to cut of the timber, with all the decorative characteristics of the timber. Material selection features, door frames: Using high-quality hardwood, such as imported miscellaneous wood, camphorwood, lauan, hemlock, etc., insetting fire and smoke proof adhesive tape
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:How to classify the grade of wall fireproof and thermal inuslation matertial?
To sum up three versions of GB8624 (1997, 2006, 2011), fire?rating of external wall thermal insulation can be basically divided into: A1, A2, B1, B2, B3 and other levels. Specific division has many technical indicators to judge. It can't be said for a moment. It is very professional and technical. For details, please contact Qingdao Shanfang Instrument. They specialized in tester of fire?rating of external wall thermal insulation 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:hat kind of fire retardant materials are there
There are many flame retardant plastics, which are modified on the basis of raw materials, such as flame-resistant ABS, flame-resistant HIPS, flame-resistant PP, flame-resistant PE, flame-resistant the PET, flame-resistant PBT, flame-resistant PC, flame-resistant PC/ABS alloy. Now there are mainly halogen flame retardant, though there are a lot of researches about halogen free flame retardant, the product stability and flame retardant effect remain to be improved. Testing methods of flame retardant materials are mainly: horizontal and vertical combustion, oxygen index method, NBS smoke box , thermal analysis, cone calorimeter, etc.
