Q:Can the teflon material resist fire?

Teflon does not burn and with the ability of flame retardant.

Q:How to distinguish the fire resistant level of the rubber and plastic thermal insulation material?

Level A of non-combustible insulation materials are: W W inorganic active wall insulation materials, cement foam insulation board, glass beads of insulation mortar, rock wool board, glass wool board and foam ceramics, ect. Th e level A is non-combustible material, characterized with low density, low thermal conductivity, high bearing capacity, convenient construction, economy and durablity, and widely used as the thermal insulation materials in hot pipes, thermal equipment and other pipe-line equipment and industrial architectures, and as the thermal insulation, heat insulation and sound-absorbing materials in industrial and civil building envelope. Because of its good thermal stability, it is more used as fire-resistant protective coating material of steel structure.

Q:What are grades of refractory materials?

Refractories have lots of varieties which all have different purposes. It is necessary to classify refractories scientifically in order to scientifically study, choose and manage them. Classification methods of refractories include chemical properties classification, chemical composition of mineral classification, manufacturing technique classification, morphology of the material classification. 1 divided according to the level of refractoriness: ordinary refractory materials: 1580 ℃ ~ 1770 ℃, advanced refractories: 1770 ℃ ~ 2000 ℃ and super refractories: above 2000 ℃ 2, divided in accordance with shapes and sizes : Standard ones: 230mm × 113mm × 65mm, no more than four ruler.

Q:How to choose thermal insulation materials for flood heating?

How to choose the appropriate thermal insulation materials: 1, Thermal insulation material shall have a small thermal conductivity, good thermal insulation properties. Besides, that also depends on whether the specific temperature changes of in the insulation materials' working environment can ensure the material has good thermal insulation. 2, when purchasing, we must be make sure it is light, and loose enough. These heat insulating material can not only afford bracket, and can also increase the heat transfer performance of the heat insulation material. prevet water penetration. Waterproof function should be soild, even if it accidentally absorbs water, its thermal insulation function must be guaranteed. 3, None of the organic material should applied to production of insulation materials, Thermal insulation material containing organic matter may get rotten, mildewed, and cause other destructive . At the same time they should not contain flammable substances, in order to avoid the fire. I hope my answer can help you

Q:What are the models of refractory cables?

NH is the firat letter of "refractory" in Chinese phonetic alphabet; It is V, not W. PVC insulation and sheath; K in KVV represents the control cable. 5 * 10 represents the cable is made up of 5 core cables whose nominal cross section is 10 square milimeter.

Q:How to distinguish the construction fire-proof material rating?

Each country has its own fireproof standards, so I do not know which country you are in ? Each country has different division levels of fireproof materials, such as GB 8624, German standard DIN 4102-1, British standard BS 476, France standard NF P92-501 and so on. GB 8624 Chinese building materials and products combustion performance division levels fireproof resources network (FireTC.

Q:What are the differences between thermal?insulation?material and refractory?

Just as its name implies, Thermal insulation means that it doesn't conduct heat instead it insulates heat inside, while refractory means resistance to high temperature and it will not be out of shape or damaged due to high temperature.

Q:Which one is the best refractory material?

Resin bonded refractory is mainly abot aluminum magnesium carbon, and carbonaceous etc. Thermoplastic resins need to add the coagulant (Uto), ageing mixture for a period of time, so the production cycle is long. Hot hard resin is relatively not so complex, but it’s not as good as thermoplastic resins in thermoplastic binding.

Q:Can anyone tell me which materials are fire-proof high temperature resistant material?

Fireproof high temperature resistant materials such as: Quartz, tridymite, cristobalite, chalcedony, flint, opal, quartzite, White silica sand, diatomaceous earth, the silicon oxide (SiO2) contained in these siliceous materials is at least 90% . The silicon oxide in some pure raw material can be above 99 %. Siliceous materials are acidic in high-temperature chemokinesis. when existing metallic oxide or contact with metallic oxide, they will conduct chemical actions and conbine into fusible silicates. Therefore, if the siliceous raw material contains a small amount of metal oxide, its heat resistance will be seriously affected..

Q:Who knows what kind of fire prevention materials are there?

Plant use general steel structure more often without too much modification. If there is a need for modification, boards which can meet the requirements of fireproof are suitable, such as gypsum boards and aluminium sheets. As for coating, it is favorable to use coating that has fine powder, high density and better sealing. Hardening agent mainly depends on the specific requirements.
