Q:What are the materials of class A fire resistant window?
Fixed class A fire resistant window should be made up of steel frame, steel casement, and fireproof glass. Fire windows, made up of steel frame, steel casement, and fireproof glass, refers to window that isolate and stop the fire from spreading. Fire window is named according to the main materials of the frame and casement. Window frame is made up of steel and casement wood, vise versa. I hope it is useful.
Q:Does the aluminum silicate thermal insulation material fireproof?
it can be fireproof and has a strong fireproof performance.
Q:what's the varieties of thermal insulation material with A level fire rating?
the main A level fireproof material is rock wool now (note:it is rock wool not mineral wool). A1 level fireproofing, now the largest producer is Taishi rock wool Co., Ltd.; hope my answer can help you, thank you.
Q:What is fire retardant coating mainly used for?
The functions of refractory coating are as follows: 1. Non-intumescent fire retardant coating is mainly used for the fireproofing of wood, fiber board and other materials, and it is used in the surfaces of wood truss, roof, doors, windows and etc. Second, the intumescent fire retardant coating can be divided into non-toxic intumescent fire retardant coating, expansible fire retardant coating emulsions, solvent-based fire retardant coating. 3. Non-toxic intumescent fire retardant coating can be used to protect cables, polyethylene pipes and insulation board. 4, The expansible fire retardant coating emulsion and solvent-based fire retardant coating can be used for fireproofing of buildings, electricity power, and cables. 5. New fire retardant coating: Transparent fire retardant coating, water-soluble intumescent fire retardant coating, fireproof emulsion paint, polyvinyl acetate emulsion fire retardant paint, water-soluble intumescent fire retardant paint drying at room temperature, fire insulation coating polyolefin fire retardant coating, modified high chloropolyethylene fire retardant paint, chlorinated rubber fire retardant coating, firewall coating, intumescent coatings, wire and cable fire retardant paint, new fire retardant coating, casting fire retardant coating and so on.
Q:Who knows the fire endurance of B-level fireproof doors and windows?
B-grade fireproof windows refer to those fireproof windows whose fire retardant limit is not less than 1 hour. Technical requirements: I. Materials and Accessories (1) Window frame should have a certain strength to ensure the integrity and stability of the steel frame or the wood frame. (2) Steel frame and mound layer can employ galvanized steel sheet or stainless steel plate. Its selection criteria should be in line with the stipulation of the Article 5.1 of GB12955 "General Technical Requirements of Steel Fireproof Doors". (3) The selection standard of wood frame and mound layer should be in line with the provision of Article 5.1.1 of GB14101 "General Technical Requirements of Wooden Fireproof Doors". (4) Filling materials inside steel frame and wood frame should be non-combustible materials.
Q:Can the teflon material resist fire?
Teflon does not burn and with the ability of flame retardant.
Q:What are the applications of refractory?
Refractory usually refers to the inorganic non-metallic material, whose refractoriness is above 1580℃. And it can be used for necessary parts. You can search more information on the Internet. It can be used in ferrous metal metallurgy, chemical, ceramics and so on. Fire material generally refers to above 1580 ℃ refractoriness of inorganic material, where the material can be used in corrosion, the network is very strong look, we know that colored when the metallurgical, chemical-resistant ceramics, etc. of industrial production high temperature. Different things are needed in different industries.
Q:How to use fireclay?
Actually, fire clay is not strong. Fireclay are all clinkers with no strength, also known as "blade mud". It is used as the filler with a thickness of not more than 3mm. Therefore, it can not be used for thermal insulation inside the furnace. Inner thermal insulation of the civil boiler can use "alumina cement", also known as refractory cement.
Q:Does the aluminum silicate fiber can be used outdoors? If not, what other refractories can be used outdoors?
Q:What is fireproofing material? Are fireproof materials the same thing with thermal insulation materials and refractories?
Insulation materials. Thermal insulation material is characterized by thermal insulation, which is one of the four traditional inorganic nonmetallic materials. Fire retardant material is cahracterized by heat-resistant. Refractory is a kind of materials of resisit high temperature. Fireproof material, which is different from thermal insulation material and refractory, is a synthetic material with some fireproof subtrate added. It is essentially resistant to high temperature.
