Q:What is refractory material?
Q:How much is refractory spraying coatings?
Different brands and models have different prices. For example: Refractory temperature: 1580 ~ 1770 ℃ | Brand: Hengli | Product category: dedicated castable for biomass burning machine | Material: castable Price: 3000.00 refractory temperature: 1770 ~ 2000 ℃ | Brand: Great Wall | Category: unshaped refractory material | Material: corundum mullite Price: Refractory temperature: 1580 ~ 1770 ℃ | Brand: Guanghuayaoye | Product category: refractory material| Material: high alumina Price: 2500.00 The above prices obtained from the Internet are for reference only, and please pay attention to the purchasing price.
Q:What is the the best ratio of mortar in refractory cement?
Specifical proportions are as following: 42.5R cement is 425 rapid hardening cement. Using the 425 cement to compound the mortar. The reducion of cement will naturally impact the workability of the mortar. The mix design standard of the mortar specifies the minimum amount of cement is not less than 200kg / m3. If it is composite mortar, and the strength and workability can be ensured, it is Ok to use 425 to compound. You can look for instructions of mixing proportion of mortar online as a reference.
Q:Who knows the setting requirements of roofing fire barrier zone?
curtain wall style architecture should meet the following requirements: The space between the inner cavity of the base wall and curtain wall and base wall, pier between two windows, window sill wall and skirt wall should be sealed by the fire-proof sealing material at each floor. I hope I can help you!
Q:What kind of flexible fireproof material is really good?
Flexible waterproof materials mostly are asphalt, linoleum and other organic material, which is also called linoleum coiled material waterproof layer. it uses the linoleum, glass cloth fabric as tire layer coil, using all kinds of cementing material phase of asphalt and so on. Make coil bind on roof structure plate leveling layer to form waterproof layer. Flexible waterproof material has high tensile strength, big elongation and light quality, which is convenient to construct. But it has relatively strict operation technology can resistant penetration and aging resistance than rigid materials, aging. Its life is short. Refers to a kind of waterproof material form relative to the rigid waterproofing materials such as waterproof mortar and waterproof concrete. In the form of its and grassroots attached two categories, it includs waterproof coating and waterproofing materials. According to different paste position of waterproof material, it can be divided into outside waterproof waterproof (outsourcing) and inside waterproof (insourcing waterproof) two kinds. Waterproof coil material must be stuck in the grass-roots that have enough stiffness of the. Before pasting, you should apply leveling layer and waterproof layer should be added protective layer of the outside, and need to make the rotation of the flexible material, the processing of subsequent and head closing, in order to ensure the continuity of the waterproof layer and sealing. In addition, there are all kinds of waterproof material and moistureproof coating material.
Q:what's the fireproof levels of fireproof and thermal inuslation matertial?
What are the fireproof levels of fireproof and thermal inuslation matertial on the market? how to divide the fireproof levels of fireproof and thermal insulation material?
Q:Who knows the roofing fireproofing and waterproof material?
Many waterproof materials are suitable for civil engineering, and almost used in the roof waterproof layer, such as: Paint categories: 911 two-component polyurethane waterproof coating single component polyurethane waterproof coating polymer cement-based waterproof coating JS composite waterproof coating and so on. . Coil categories: single-sided waterproof roll double-sided self-adhesive waterproof roll modified asphalt waterproof roll (SBS, APP) polypropylene, polyester, polymer waterproof roll, PVC waterproof roll, EPDM waterproof roll
Q:What's the poured refractory material?
Frequently used poured refractory material: AZS brick, corundum brick, direct-bonded magnesia-chrome bricks, carborundum brick, silicon nitride bonded silicon carbide brick, nonoxide refractories like nitride, silicide, sulfide, boride and carbide, and oxide refractories like calcium oxide, chromium hemitrioxide, alumina, magnesium oxide and beryllia.
Q:What are the differences and connections between softening temperature of the refractory under a fixed load and thermal resistant creep property of the refractory?
The result of refractoriness under load is temperature while the result of creep is percentage of deformation. Refractoriness under load and creep can be tested by an instrument. Refractoriness under load reflects the temperature in which the deformation reaches a certain degree under the condition of load. Creep reflects the deformation refractory has under the condition of constant temperature and load. Both refractoriness under load and creep are important criterion for the operating temperature of refractory.
Q:What's the fireproof specification for constrcution external wall thermal insulation materials?
incombustible material: Class A1 (homogenous): such as YT inorganic active insulation material for wall thermal, foam glass, rock(ORE) wool, glass wool, insulation board of aerogel,expanded perlite series, expaned glazed hollow bead, foam insulation boards, ETC. Class A2 (non-homogeneous composite): such as phenolic foam, gelatine powder polyphenyl granule thermal insulation material, inorganic coating materials and other nonflammable material. phenolic foam insulation board, urea resin foam and board, high flame-retardant polyurethane rigid foam and board, high flame retardant polystyrene cystosepiment, gelatine powder polyphenyl granule heat insulating slurry and other combustible materials. Requirements for combustion levels of common antiflaming EPS, common inflaming retarding XPS, common antiflaming rigid PU foam board: Class A is incombustible material (product); B1 nonflammable material (product); B2 combustible material (product); B3 combustible material (product).
