- Q: How is grade of fire endurance divided?
- You can search the answer on the Internet, thank you!
- Q: Who knows what is the requirement for fireproofing of interior decoration materials ?
- In addition to the underground building, combustion performance level of interior decoration materials inside windowless room , in addition to a class, should advance 1 level based on the original provisions . Library, archives and rooms storing artifacts, ceilings, walls should use class A decoration materials, and the ground should use decoration materials no lower than class B. When high temperature parts of lighting and lighting lamps and lanterns are close to non - grade A decoration materials should be taken, fire prevention measures such as thermal insulation and heat dissipation must be taken. Combustion performance level of materials used for lighting should be no lower than B. Kitchen ceiling, wall and floor should used class a decoration materials.
- Q: What is the principal part of silicious refractory material
- Silicon nitride and aluminite powder as well as dextrin
- Q: what is the requirements of roofing insulation materials fire rating?
- The fireproofing requirements of architectural design are regulated by architectural design fire?safety?rules, roofing insulation material only has the requirements of materials combustion performance, namely non-combustible material. No fire rating requirements.
- Q: How to choose thermal insulation materials for flood heating?
- 1, Select the appropriate floor material suitable for radiant floor heating. The floor radiant heating system mainly transfer heat through the ground concrete and the ground material to the room. Therefore in the heating season the ground material will always be heated during heating season. Therefore, it is better to choose stone materials and compround floor plate insensitive to tenmperature change with good heat dissipation and functions. Currently, wood floor is not suitable for the ground radiant heating system. 2, choose the pipe with anti permeability performance. Plastic floor heating pipe itself has a certain air permeability, if oxygen penetrates in it is prone to oxygen erosion and system's mental device will be eroded, resulting in the risk of leakage. Therefore in order to ensure the reliable operation of the heating system, the selected pipe must have anti oxygen permeation performance, and meet the standard stipulated by the DIN4726 oxygen permeation quantity: and be less than 0.1mg\L.d at 40 C.
- Q: Who knows the fire resistant level of the rock wool color plate?
- Hello; Same with other unprotected steel, the fire endurance of the color steel?plate is generally 15 minutes. It is not a fireproofing material, let alone fire resistant level. If the color steel plate has sprayed fire retardant coating and the thermal insulation filling material in the core is rock wool fiber, it can achieve A level fireproofing requirements. The color steel?plate refers to the painted steel plate, which is a steel plate with organic coating. The color steel board is divided into the single plate, color steel composite board, floor support board, ect. It is widely used in large public buildings, public plants, portable dwelling, and integrated housing walls and roofings. I hope that will help you.
- Q: What material is used for making refractory stone bowl?
- It is attractive and diverse in appearance, hard, and heat fast, not stick food when using. The cooked food is attractive and delicious and rich in various trace elements which is beneficial to the human body. It is also of high quality, and all these make it popular among the customers.
- 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: How to classify fire resistance rating of brick-concrete structure?
- In order to ensure the safety of the building, the fire protection measures must be taken to make it have a certain degree of fire resistance, even if there is a fire, it will not cause too much damage. According to the national conditions of our country, and in the light of other countries standards, < high-rise civil building fire protection design specification > defines fireproof rank of high-rise civil buildings into level one and two; < code for fire protection design of buildings > divides the rank into level one, two, three, four, level one is the highest level, level four is the lowest. Besides that the minimum fire resistance of the building component is specified, buildings of fire resistance rating also specified requirements for combustion performance. Because the component with the same fire resistance limit is different, it is different in the fire.According to our country national standard < building design fire protection code >, the fire resistance rating of the building is divided into four levels. The fire resistance of a building is determined by the combustion performance and fire resistance of building components (such as beams, columns, floors, walls, etc.). Generally speaking, the fire resistance building of level one is a mixed structure of reinforced concrete structure or a mixture of brick wall and steel concrete structure; the fire resistance building of level two is a mixed structure of steel truss structure, reinforced concrete column and brick wall; the fire resistance building of level three is brick-wood structure made of wood roof and brick wall; the fire resistance building of level four is combustible structure which is composed of wood roof and non-combustible wall.
