Q:What kind of refractory decorative board has good quality?
Baby Rabbit has excellent refractory decorative board. It once won the Chinese famous brand, and was awarded iconic brand in plywood industry and the most influential integrated service providers of indoor decoration materials . Fireproof panel is made from body paper(titanium coated paper, kraft paper) in high temperature and pressure through impregnation technology of melamine and phenolic resin. Refractory door slab is made by sticking fireproof panel on base materials such as density board or chipboard.
Q:What is the biggest difference between refractory bricks and clay refractory bricks? Where can I find information on the refractory bricks?
You can look up knowledge manual of refractory material to find phosphatic material, etc. Xinjiang refractory bricks, castable refractory, refractory material, silicious, corundum and alumina-magnesia: High alumina and clay refractory bricks can be divided into
Q:I would like to ask a friend that how much is the fire endurance of level A fireproofing glass?
Fireproofing doors can be divided into Class A, Class B and Class C by the fire endurance, the fire endurance is seperately not less than 1.20h, 0.90h and 0.60h. Fireproofing glass is a kind of special glass which can retain its integrity and insulation in the prescribed fire test, it can be divided into three categories according to fire resistance rating: class A is the fireproofing glass with refractory integrity and refractory thermal insulation. Such glass has the properties of transmittance, fireproofing (smoke insulation, fire insulation, heat radiation shielding), sound insulation and shock resistance, which is suitable for architectural steel and wood fire doors, windows, partition walls, daylighting roof, ceiling screen, perspective floor and other building components required both transparent and fireproofing. Class B is a fireproofing glass with refractory integrity and thermal radiation intensity. Such fireproofing glass is mostly composite fireproofing glass with transmittance, fireproofing and smoke insulation. Class C is a fireproofing glass with refractory integrity. Such glass has the features of transmittance, fireproofing, smoke insulation and high strength. it can used in partition wall, fire window and outdoor curtain wall without the thermal insulation requirements. fireproofing glass can be divided into composite fireproofing galss and monolithic fireproofing glass by the structure.
Q:Who can tell me what is neutral refractory?
Refractories mainly refer to aluminum oxide, chromium oxide and carbon as the main component of refractory materials, such as corundum brick, high alumina brick, and carbon brick. Its characteristic goes to the resistance to both acidic and basic slag. Basic refractories mainly refer to the refractory materials whose mian components are magnesium oxide and calcium oxide, including magnesia bricks, magnesia-alumina bricks, magnesia chrome bricks, dolomite bricks, etc. Basic refractory is good at resisting basic slag erosion.
Q:Which fireproofing materials factory is the best in Xiangyang?
Xiangyang Tianhua Fireproof Materials Co., Ltd. has a variety of products with complete specifications. The products include fireproof cable tray, fire resistant groove, fire-resistant shield, ATD-AB, organic fire-proof caulking, intumescent fireproof pillow, fire retardant module, cable refractory coating, ultra-thin fireproof coatings for steel structure and other products. All products have passed the relevant tests and inspections, all performance indexes are in full compliance with national or industrial standards, and meet the technical requirements of cable fireproofing. Xiangyang Weicheng Fireproof Materials Co., Ltd. is specialized in research and development of fire-fighting apparatus and fire retardant materials! It's main products: fireproof bag, asbeston, fireproofing mud, and other types of fireproofing materials.
Q:Using what kind of melting aluminium furnace refractories is more appropriate?
If it's the ordinary, you can use high aluminum refractory brick with general clay, GB/T 3994-2005 clay heat insulation refractory brick. If you need these with good material, there is high alumina thermal insulation refractory brick, GB/T 3995-2006 high aluminum heat insulation refractory brick, models have A13 and material is the alumina, A13 50 u, high insulating brick B5.Intermediate insulating brick B2, etc. Dolomite brick: good hang kiln performance, good erosion resistance, but brick is usually without f - CaO, hydration, and difficult to transport and storage, less used in the production. Magnesia-chrome bricks: good hang kiln, used in calcining zone. The disadvantage is that its thermal shock resistance is poor and plus hexavalent Cr is toxic, the production and use of magnesite chrome bricks in international countries gradually reduce. Now unit using the brick find replacements as soon as possible.
Q:What are the chemical composition of refractory cement?
Calcium aluminate prepared by calcining as the main component. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. Refractory cement is also known as aluminate cement.
Q:Can refractory be used as sealing element?
It can. For example, a kind of irregular part that is made of fiber or some injection mix is used for sealing things.
Q:Is it necessary for the frame of glass fireproof door to be crammed with fire-proof material?
Fire resistance steel door——means that use a cold rolled steel sheet as door frame, door plank and framework, and stuff a door leaf with incombustible material.
Q:What kinds of fireproof and fire retardant materials are there?
It is the fire retardant material is not completely fireproof. It is time-limited.
