Q:How long is the fire endurance of the rock wool board?
The rock wool board takes the basalt as raw material and is processed into artificial inorganic fiber through high temperature melting, which is light in weight, non-combustible, heat absorptive, small in thermal conductivity. The initial development in construction is a common type of application used for industrial buildings, which should be consistent with the requirements of "building insulation application categories and basic requirements" . In June 1981 the pre-launch succeeds. The rock wool board is a new type of insulation, burning compartment and sound-absorbing material. Generally the fire resistance of the rock wool board is 140-180 degree within two hours, It is best not to exceed this safe period, in order to avoid security risks.
Q:Who knows what is the standard of insulation material whose fire proof is level A?
Fire insulation materials of level A is non combustible building materials, and does not have any burning material. Level A1: single inorganic non combustible, no open flame. Level A2: A2 level: composite organic non combustible, that is, composite materials, non flammable, smoke volume should reach the standard.
Q:What characteristics do A grade external wall fireproofing material have?
1. Save space and reduce costs; 2. Fireproofing, green and environmental protection; 3. Waterproofing; 4. Sound insulation; 5. Thermal insulation; 6. Install easily and shorten the construction period; 7. High safety performance.
Q:What are the application of old refractory bricks?
It can be used for refractory bricks again, as long as the quality is good. It is much more cost-effective than Bayerite.
Q:About the market issues of thermal insulation material and refractory material.
After all, most people have the characteristics of being accustomed with something and it will not change easily ; second, the South has few material manufacturer, but in the Northeast, there are thermal insulating and refractory material manufacturers, which is in shortage, however, but irt is in the minority, and in many areas it is not suitable for exploitation of mineral (due to heavy industry and agriculture land and other reasons). I hope that my answer will help you. first, in the Northeast, the refractory material is not very rich, but the thermal insulating and refractory material demand is very large; third; fourth, which material is used more relived, after all, we should take the transportation costs into account, and it will depend on the kilns construction engineers being willing to use which kind of material, and the thermal insulation material procurement in northeastern region is mostly from the north.
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:Does anyone know the fire endurance of steel stud partition?
The fire endurance degree is 1 hour. which is in line with the national building material fireproofing test standards. CaSo4.2H2O is molecular gypsum molecular structure formula, containing 20% ​​water, crystal water and free water, when putting on fire, 10% of the surface water will slowly evaporate, remaining10% of crystal water. It is a class A fire retardant material itself. The longest time can be 4 hours.
Q:Which refractory quality inspection authority is good?
Research Institue of Refractory Materials in Luoyang, Henan Some of our samples are made there.
Q:What is the fire resistance thickness of the thin fire-retardant coatings?
There is no detailed requirement on the thickness of the thin steelwork fireproof coatings in the "Code for application technology of steelwork fireproof coating", and the thickness there refers to a certain thickness which must(at least) have fire resistance for a certain time. The thickness of fireproof coatings in engineering generally depends on the manufacturer's test reports. Our thin steelwork fireproof coatings: the fire resistance is 2.5 hours, the thickness is 4.9 mm, the fire resistance is 2.0 hours, the thickness is 3.5 mm, the fire resistance is 1.5 hours, the thickness is 1.75 mm, the fire resistance is 1.0 hours, the thickness is 1.17 mm.
