Q:What are the fireproof materials for Class A roof insulation?: At present, only phenolic board can meet the requirements, the test temperature of 2000 degrees, no droplets, good integrity. The thermal conductivity of non-combustible, non-toxic, smoke-free!

Q:Height greater than 60m residential building construction, when the use of B1-class insulation material, every few layers to set the level of fire isolation belt?: Now the external wall insulation materials are required to reach A level, see "Gong [2017] 65"

Q:A1 grade external wall insulation materials which: At present, only rock wool, glass wool, ceramic fiber, foam glass, inorganic insulation mortar, a1 grade materials generally should not contain organic materials.

Q:Polyurethane fireproof material really effective?: This ad, I also served

Q:Plastic products in the classification of fire levels is how the standard ah?: Flammability UL94 grade is the most widely used standard for combustible properties of plastic materials. It is used to evaluate the ability of the material to be extinguished after being ignited. According to the burning speed gallbladder Ding book scratching calcium difference water to promote the alarm, burning time, anti-drop ability and drop beads can burn a variety of judging methods. Each test material can be a lot of values ??depending on color or thickness. When a material of a product is selected, its UL grade shall meet the thickness requirements of the wall part of the plastic part. UL grade should be reported along with the thickness value. It is not enough to report only UL grade without thickness. Plastic flame retardant grade by HB, V-2, V-1, to V-0 step by step increase. 1.HB: UL94 standard in the bottom of the flame retardant grade. Requires a sample with a burning rate of less than 40 mm per minute for samples of 3 to 13 mm; a sample less than 3 mm thick, a burning rate of less than 70 mm per minute; or extinguished at 100 mm mark. 2. V-2: After two 10 seconds of burning test, the flame was extinguished in 60 seconds and no burner could fall. 3.V-1: After two 10-second burn tests on the sample, the flame was extinguished in 60 seconds and no combustibles could fall. 4.V-0: After two 10-second burn tests on the sample, the flame is extinguished in 30 seconds and no combustibles can fall.

Q:What is the bulk density of rock wool A grade fireproof material?: Rock wool board capacity of 80-200 range

Q:Is the soundproof cotton a fireproof material?: Can be said to be ,,, but not that he will not burn, I tried to burn with fire, when we still fire when he was still burning, the fire that went to immediately off, that he is flame retardant of,,,

Q:Is the material inside the fire door gypsum board?: No, it is fire board (perlite).

Q:Why do the cabinets in the bathroom use fireproof board material, the bathroom is easy to fire?: Because the fire board has: waterproof performance. The concept of the fire board is easy to confuse with the professional name. In fact, the fireproof plate we talk about is the fireproof sheet (for example, on the cupboard). It is made of fireproof board (or fire board veneer) and substrate MDF or particleboard) by hot sol high temperature and pressure made by paste. Fireproof board (fire board veneer), also known as fire board, formerly known as thermosetting resin impregnated paper high pressure decorative laminated board, abbreviated as HPL, is a surface decoration with refractory building materials, a rich surface color, pattern and special Physical properties and ease of processing, widely used in interior decoration of the surface material. It is impregnated with phenolic resin for the core (bottom) layer and the amino resin (mainly melamine resin) impregnated paper for the surface layer by heating and bonding at a pressure of not less than 5MPa, the outer layer of one or two A decorative color or pattern. Fire board / fire board is the base paper after melamine resin and phenolic resin processing, the main physical properties are shown by the resin characteristics. Melamine resin thermosetting after a good gloss, good transparency, high surface hardness, wear resistance, high temperature, impact resistance, surface pores are not easy to be pollution, chemical resistance, water resistance, solvent resistance, Such as excellent performance, mechanical strength, electrical insulation, good arc resistance and easy aging. Phenolic resin resin after heat curing and heat and hard and other properties. After the combination of two resins, fire board / fire board both the performance of both.

Q:What does the fire door frame fill with?: According to the region can not, the requirements are not the same, and some areas require grouting (ie, cement mortar), some areas can be filled.
