Q:How is the grading of the level A new material fire insulation material?: The standard to distinguish level A and level B is the different fireproofing coefficient. The level A is non-combustible. The level B is divided into B1, B2 and B3. B1 is flame retardant, B2 combustible and B3 flammable. The level A is commonly phenolic aldehyde, rock wool, thermal?mortar, foam ceramics, foam glass and foam concrete on the current market. Among the advantages of level A materials, the biggest one is foam concrete currently, also known as foam cement, which the Xuzhou Green Year EEB company's main produces.

Q:How is the performance of refractory materials?: It is a little difficult to answer. There are some requirement for refractory materials, such as fire resistance, softness, creep, thermal shock, abrasive resistance. Besides, requirements for construction performance include: Liquidity, plasticity and other linear change rate, volume density, strength (including high temperature) and all other important indicators must be tested the same conditions with the use of test conditions and test items like body density, strength, line changes in the basic project

Q:What things and cement mixed can act as refractory?: Cement acts as cementing material. Itself works by refractory aggregate and stir the refractory material for its gelling refractory aggregate both should be fire-resistant.

Q:Who knows how many kinds of fireproof insulation materials are there in the market?: The so-called A-level materials in fire insulation materials, namely, the WW non-combustible insulation materials, and the WW material s are A-level. Inorganic fireproof and thermal insulation materials can be used as wall insulation materials to replace red bricks, therefore, they, as thermal and cold insulation materials, can reduce the thickness of walls, and save energy, as well as expand applicable areas indirectly, decreased structure weight. They are very good.

Q:which is better as household fireproof material ?: If it is from the perspective of fire rating inorganic active insulation material for wall thermal, cement foam insulation board, glass beads of insulation movitrified?micro bead?thermal insulation?mortar, rock wool board, glass wool board, ect.. thermal insulation material are Class A fireproofing, polyphenyl board, extruded sheet, phenolic foam board, Polyurethane board, ect..belong to B1 level fireproofing, if it is used for external wall thermal insulation in decorative board, then rock wool board is more often used.

Q:What kind of material is refractory fiber?: Refractory fiber, also known as ceramic fiber, is fibrous thermal insulation refractory. It has the characteristics of ordinary fibers, such as softness, flexibility, having a certain tensile strength. And it can be further processed into a variety of products such as paper, wire, rope, tape, blankets and felts.

Q:What are included in fireproofing materials?: There are many types of fireproof materials, and the following listed below is the main species: All kinds of fire retardant coating such as finishing fire retardant paint, fire retardant coating components, fire-resistant coating for steel structure; all kinds of fire-proof materials such as fire?retardant material and its products, textile, fire?retardant fabric, building materials and products, flooring material and external wall thermal insulation system; all kinds of fireproofing components such as fireproof?panel, fire door, fire resistant window frame, fire resisting shutter, fireproofing glass, elevator landing door,ventilating duct, fire-proof?sealing?material and fire protection smoke exhaust fan. The main indicators to judge fire resistance are: Flame retardency, ignition,production of?toxic?gases, smoke density,heat release and exhaust gas; fire resistance, combustion performance, heat of combustion, fire-resistant performance, high temperature resistance, fire?rating, etc. There are some specific parameters which need to be judged by a professional testing equipment. You can go to the inorganic laboratory to check. The test results of fire rating are accurate.

Q:What type of firebrick does TZ-3 represent?: Height is 65mm, length is 230mm, and width is 114mm, that is the t-3 firebricks which meet the national standard.

Q:Are the rubber insulation materials are refractory materials?: It's not.
