Q:What materials are needed to make the amorphous refractory bricks?
I am so glad to answer your question. The amorphous refractory brick is composed of a certain proportion of aggregate and powder, a binder and an additive.
Q:How long is the duration of fire resistance of hollow glass magnesium board
Glass magnesium board is non-combustible board with excellent fire resistance ability, the continuous burning time of flame is 0, non-combustible at 800℃, no flame at 1200℃, achieving the highest level of fire retardant level A1; Partition System cooperated with high-quality keel can endure fire for more than 3 hours. In the process of combustion, a large amount of heat energy can be absorbed, and the temperature of the surrounding environment will be delayed.
Q:How many kinds of A-level fireproof and thermal insulation materials are there?
A-level non-combustible materials are mostly inorganic thermal insulation materials, as well as some organic compound materials can also be non-combustible; but if the convenient construction is required, panels are exempted, you can only choose inorganic thermal insulation mortar.
Q:Who can tell me the properties and classification of insulating refractories?
Bubble method. This method is the foam agent in a frothing machine mixing with water and prepared uniform fine foam, the foam added in common mud mixing into the foam slurry injection model, together with the drying, demoulding, at 1320 DEG C to 1380 DEG C (high alumina insulating refractory brick for burning) after processing, the plastic products.
Q:what is the Specifications Grading for Fireproof rubber insulation materials ?
External insulation materials, welded wire mesh matt external wall insulation, external wall thermal insulation mesh matt. 1,inorganic activel thermal insulation materials 2,silicate thermal insulation material 3,ceramic thermal insulation 4, gelatine powder polyphenyl granule, 5,teel wire gauze picking cement cystosepiment(Estazolam platepowder particles)6 extruded sheetXPX. 7,Rigid polyurethane coating at the scene, Polyurethane insulation board8,rigid polyurethane foam,9EPS foam board roofing materials. 1, a ceramic insulation board 2, xps extrusion board 3, perlite and perlite brick 4, vermiculite and vermiculite brick heating, air conditioning Material: Phenolic resins, polyurethane waterproof thermal insulation integration, sponge rubber, polyethylene, polystyrene foam, glass wool, rock wool Steel material: Polystyrene, extruded sheet, polyurethane panels, glass wool carpets and the like. Five inorganic thermal insulation materials: Foam cement, DY inorganic active insulation system super thin vacuum insulated panel for building external walls .
Q:What kind of materials can be tested their electrical resistivity in the current refractory industry?
fused cast bricks, fused zirconia corundum blocks, corundum, high zirconium
Q:what's the fire endurance of fireproof panel?
non-asbestos calcium silicate board, fireproof panel partition will excced over 4 hours, two single 75 keel. 12 mm fireproofing calcium silicate board partition, through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 4 hours.
Q:Graphite and other carbon materials may be oxidized to CO or CO2 at high temperatures. But why can they be refractories?
There is no contradiction for this. Any substance can be combustible, but different materials have different ignition points.There are many types of graphite. Pyrolytic graphite has a much lower ignition point. Therefore, as long as it reaches at a certain temperature, it can convert into graphite. Mostly, in practical applications (such as brake pads will add a certain amount of graphite), graphite is required to have refractoriness of below 1000 ℃. Graphite can serves as both the combustible and refractory material. So, it can be used as a fire-resistant and high-temperature-resisrant material because graphite (lamellar graphite) has a ignition point of at least 3000 degrees in an oxygen free condition. The above information is for reference only and is offered by Xin Ruida Graphite Company.
Q:What is refractory material?
Q:What is the common inorganic fireproof and thermal inuslation matertial?
inorganic materials of insulation materials 1, inorganic thermal insulation materials are mainly concentrated in the materials that have a certain insulation effect and can achieve level A fireproofing, such as aerogel blanket, glass wool, rock wool, expanded perlite and micro-nano thermal baffle. 2, rock wool production is harmful to human body, workers also do not want to occure the situation under the construction. The cycle of rock wool construction plate is long about 2 years from construction to production. The supply of the domestic wool market also cannot meet the requirements for use. 3, expanded perlite has great weight and high water absorption. 4, the insulation performance of micro-nano insulation panels is 3-5 times that of conventional insulation materials, commonly used in high temperature environment, but is more expensive. 5, aerogel blanket is level A1 inorganic fireproofing building materials, thermal conductivity at room temperature is 0.018W / (K · m), and absolutely waterproofing, its insulation performance is 3-8 times of traditional materials, which can replace the unenvironment-friendly froconventional flexible material with poor insulation properties, such as glass fiber products, asbestos insulation felt and silicate products.
