Q:What is the thickness of the thick fireproof coating?

According to GB-2002 "steel structure fire retardant coating" provisions: thick: coating thickness of 745mm in the fire retardant coating: coating thickness of 3-7mm in the fire retardant coating: the thickness of less than 3mm coating thickness of the fire Type fire retardant coating is non-intumescent steel structure fire retardant coating, generally by: binder, inorganic refractory insulation materials, additives and other components. The coating does not expand in the case of fire, through its own insulation performance of the protected components to improve the fire resistance time.

Q:The fire resistance of building materials includes the nature of building materials

The burning performance of a building material refers to all physical and chemical changes that occur during combustion or fire, which is caused by the fire and flame propagation of the material surface, heat, smoke, carbonization, weight loss, and toxicity Produce and other characteristics to measure. China's national standard GB8624-97 will be the burning of building materials into the following grades. Class A: Noncombustible Building Materials B1 Grade: Flammable Building Materials Grade B2: Flammable Building Materials B3 Grade: Flammable Buildings Lawyers Unrestricted Karma Karma Stuck But Stem Material Section 2 Combustion Performance and Fire Resistance of Building Components limit

Q:What are the general differences? The The

LS said the two are modified plastic, that is, the material may itself is not good flame retardant, but by adding flame retardant, you can make the material to achieve a certain level of flame retardant, in other words, that is, most of the material added Flame retardants have flame retardant properties, but this should not be the answer to the landlord want it fundamentally speaking, the flame retardant test material is to see the material off the fire after the extinguishing time, or material burning time, according to material Different, different sizes, different testing methods, of course, there are many natural flame retardant materials, such as PVC (PVC) without adding flame retardant, it is extinguished from the fire. (PEEK), polyetherimide (PEI), polyphenylene sulfide (PPS), polyphenylene sulfone (PPSU), polyphenylene sulfide (PPS) , Polyether sulfone (PES), polyvinylidene fluoride (PVDF) and liquid crystal polymer (LCP) and so on. PBT itself is not very good flame retardant, halogen-free flame retardant can also be modified, the so-called halogen-free flame retardant or halogen-containing flame retardant, it means that the use of the taste is a bit of fat, Flame retardant, halogen-containing combustion in the general produce toxic gases, but the flame retardant effect is very good, the price is low. As for how you mention the difference, do not know what you want to distinguish, I feel you are not like to ask how the difference between the plastic resistance is not flame retardant, the general is a direct test friends, fundamentally speaking, and molecular structure has a great relationship, such as PVC (Polyvinyl chloride) containing Cl, burning produce HCl, so the flame retardant effect is good, but the HCl toxic, look at the polymer aspects of the bar, I hope to help you

Q:Is it necessary to provide a fireproofing material for decoration works? Such as the use of the hanging plate.

Must be checked. Another correction, you said the burning board, such as ordinary paper gypsum board, does not belong to fire protection materials, although it belongs to B1 level. Refractory paper gypsum board is the fireproof material.

Q:Indoor to do with the gypsum board or good or good use of fire board board, fire board is made of what material ah how environmental

Do wall, then, gypsum board preferred. Cheap, sex Geng Ji Li Li Dian Dian for the bite force can be good. Do not use wood, moisture easily deformed! Fire board is now called the law is not uniform, there are metal panels inside the folder perlite. There is also a layer of wood on the surface of a fireproof material. As well as take carpentry in the fire liquid soak! The Do not know how the decoration company told you! The
