- Q:Who know what kind of fire shutter fire rating are there?
- There is no national standard for fire protection performance of fire roller shutter in China, and now the executive standard of GB14102-2005 "fire shutter": F1, fire-resistant time 1.50h; F2, fire-resistant time 2.00h; F3, fire-resistant time 3.00h; F4, fire-resistant time was 4.00h before the national standards of fire shutter grading is introduced, expert advice that fire resistance test be made according to national standard, to reach back fire surface temperature rise requirements, if the refractory limit is greater than or equal to 3.0h, it is said to be super fire shutter, if test not inspect unexposed surface temperature rise as a judgement of the conditions, the door is referred to as ordinary fire shutter doors. I hope my answer can help you
- Q:what's the detailed address of fireproof and thermal inuslation matertial market?
- Detailed address of fire insulation materials market is as follows: A: Guangzhou Huatai building materials co., LTD. Address: Guangzhou Tianhe Chepo Road no. 10 B: Address of Donglong building materials market: Guangzhou Tianhe Taian North Road no. 7 C: Address of Huiya building materials trade market : Guangzhou Tianhe Sports West Road No. 109
- Q:What is the limit of fireproof rolling shutter?
- According to the national standard 14102-2005 GB standard, the provisions of 14102-2005 GB specify that: According to provision 14102-2005 GB: If fire resistance limit of fire resisting shutter is no less than 3 hours, it is AAA fireproof rolling shutter. Therefore, the fire resistance limit of AAA grade fireproof rolling shutter should be 3 hours.
- Q:What types does refractory floor include?
- There are many types refractory bricks, including silicon aluminum refractory brick, the leading product in refractory bricks. And its high temperature resistance can reach up to 600 degree centigrade or more, so it is an excellent refractory brick. And this high-alumina refractory brick is very suitable for metal industry for its strong practicability. Another one is alkaline series refractory brick, including magnesite refractory brick, and these two bricks are good materials resistant to high temperature.
- Q:Is it necessary for the frame of glass fireproof door to be crammed with fire-proof material?
- Close the door , and check if the gap is normal, whether the hole and the door leaf are in the same plane, and whether the door leaf has tendency to fall down. Fire resistance steel door——means that use a cold rolled steel sheet as door frame, door plank and framework, and stuff a door leaf with incombustible material.
- Q:What kinds of refractory materials that can resist 3,000 Celsius degree?
- steel fiber reinforced spalling resistant bricks, phosphate bonded high alumina brick with high strength and wear-resistance, and high R.U.L bricks and composite bricks
- Q:Who knows about the fire endurance of grade C fire doors?
- The fire endurance of grade C fire doors is no less than 0.5 hours. As the key role of family fireproofing, fire doors is particularly important. It can be classified according to the fire endurance and thermal insulation performance: The fire endurance of grade A fire doors is not less than 1.5 hours; that of grade B fire doors is not less than 1.0 hours; and that of grade C fire doors is not less than 0.5 hours. We can choose in accordance with different needs, but commonly used fire doors are grade A and B fire doors now.
- Q:How long does it take for refractory cement to solidify?
- 1. First you should be aware of the concepts of condensation and condesation time. Refractory cement belongs unshaped refractories, which when added water or liquid binding agent to mix, the agitation material will gradually lose thixotropy or plasticity and become in a state of solidification, thus is solidified. The time needed to finish the process is called solidification time. The whole process is divided into initial and final set. When beginning to lose plasticity called the initial setting, when called plasticity completely lost the final setting. 2. For refractory cement, the solidification time depends on the matching of the material and the parts and using methods. Under normal circumstances, in order to meet the requirements of time of construction, the initial set time should be no shorter than 40min, and the final set time should be no longer than 8H 3. There are also some exceptions. When refractory cement is used for spraying and injection operation together with other refractory castable, the set time is required as short as possible, sometimes flash set is required to prevent the occurrence of peeling or collapse of the spraying layer.
- Q:Which kind of furnace hearth refractory is better?
- Coal is acidic medium, so the matched material should be acidic refractories oriented, like silica?bricks. For example, the coking coke oven and carbon furnace made of carbon are in reducing atmosphere, so they use silica bricks which have low price and good high-temperature indicators. If the part has special requirements, you can then consider other refractory on request.
- Q:Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?
- If the outer packing is made of solid wood, it must be fumigated! If it is not solid wood, you can do without!
