Q:What's the requirements of fire-fighting criteria of heat insulating material?
It shouldn't be under than B2 level. Roofing insulation fire rating requirements: the ministry of public security, housing and urban-rural development department issued about printing and distributing the civil building external thermal insulation system and the interim provisions on the exterior wall decorative fireproof prescribed in the notice: roof grassroots adopted duration of fire resistance is the non-combustible component that shouldn't less than 1.00 h's. Its roof insulation materials should not be below B2; Otherwise, the combustion performance of insulating material should not be below the B1 level. The junction of the roof and wall, the insulation layer around the opening part of roof should use the grade A thermal insulation material to set level fire-fighting belt that width is not less than 500 mm.
Q:what kind of refractories is used to make the industrial silicon furnace mouth long life?
Fused zirconia corundum brick, the smelter of the glassworks is used this kind of lining, and you can contact by private letter.
Q:What kind of foundry ingot refractory materials are there? Please be more detailed.
Classification of refractory materials used in foundry smelting process: refractory brick, siliceous brick, high alumina brick, corundum brick, magnesia brick, magnesia brick, magnesia carbon brick. Unshaped refractory materials: ramming material, castable, refractory cement, silica, magnesia, etc.

Q:How long does it take for refractory cement to solidify?
1. First you should be aware of the concepts of condensation and condesation time. Refractory cement belongs unshaped refractories, which when added water or liquid binding agent to mix, the agitation material will gradually lose thixotropy or plasticity and become in a state of solidification, thus is solidified. The time needed to finish the process is called solidification time. The whole process is divided into initial and final set. When beginning to lose plasticity called the initial setting, when called plasticity completely lost the final setting. 2. For refractory cement, the solidification time depends on the matching of the material and the parts and using methods. Under normal circumstances, in order to meet the requirements of time of construction, the initial set time should be no shorter than 40min, and the final set time should be no longer than 8H 3. There are also some exceptions. When refractory cement is used for spraying and injection operation together with other refractory castable, the set time is required as short as possible, sometimes flash set is required to prevent the occurrence of peeling or collapse of the spraying layer.
Q:What are fireproofing materials?
1. With the tape made by double-coated flame-retardant and chemical defense surface adhesive and that only occurs charring with no melting drops and maintains good strength when meeting with fire as main material, and by the laminating-sewing-pasting process, clothing body and gloves are made and equipped with flame retardant, chemical defence, voltage resistant, and puncture resistant boots, the clothing assembly is constituted. 2. They are usually asbestos. Some of them have better quality and are made by wiredrawing of aluminum zirconium and silicon mixtures, and of course others are directly manufactured with some natural objects. 3. All the panels that meet the first-order fire protection requirements can be fireproofing materials. Like gypsum boards, aluminum sheets and so on. Coatings are usually those with fine powder, high density and good sealing. 4. Phenolic foam board can meet the requirement and its test temperature can reach up to 2000℃ under which it has no molten droplet but good integrality. Thermal Conductivity: 0.03W/(mk). It is non-flammable, non-toxic and smokeless! 5. The hollow ceramic micro-bead is good in thermal insulation and fire-retardance.
Q:As for fireproofing material rock wool and glass wool, which one is better?
First of all, glass wool and rock wool fireproof materials, rock wool and glass wool belong to Class A fireproofing rating, secondly, rock wool can endure high temperature of 800 degrees, glass wool high temperature of 450 degrees, again,unit weight of rock wool is relatively heavier and unit weight of glass wool is lighter, finally, glass wool has better waterproof performance.
Q:What's the refractory material?
Main components of basic refractory are magnesium oxide and calcium oxide, and magnesia brick is commonly used. For the magnesia brick with magnesium oxide content of more than 80%-85%, it has good resistance to basic slag and scum, and it has higher refractoriness than that of the clay brick and silica brick. It is mainly applied to the open hearth furnace, oxygen-blown converter, electric furnace, non-ferrous metal smelting equipment and some high-temperature devices.
Q:I am a refractory material manufacturer, sold products, money is always not back, anxious to die, what is the way?
Many manufacturers are facing the same problem, difficult to find the order, order the payment contract is more difficult, it is difficult to have binding, the better solution is to seek third party secured transactions, see the whole production or see full delivery
Q:What are the insulation fireproofing materials?
Asbestos is the most common. Asbestos containing zirconium and made of the mixture of zirconium aluminum and silicon through wire drawing is better. Of course, some are made directly from natural things which can withstand 1400 degrees for over 30 seconds while the internal temperature had no significant change, and withstand 1400 degrees for over five minutes while inside temperature increase does not exceed 5 degrees.
