- Q: How long can gypsum board endure fire?
- General gypsum plaster board with a thickness of less than 12mm has a fire endurance which is less than half an hour. Scheme One of gypsum board partition system by using 75# series of lightgage steel joist: separation distance of keels keep 600mm in vertical direction. The thickness is greater than 0.5mm; gypsum board: it shoule be the board of double-sided and single-layer with the thickness of 12mm. Fire-resistant gypsum plaster board's fire-resistance limit: 1 hour. Sound insulation index: over 35 rwdb.
- Q: How to detect the acid resistance of refractory? Is there any standard? Thank you
- Setting the acid resistancere of fractory products is simple; R22, two measurement methods are both bricking refractory products, using the mass fraction of the original dry to indicate. It is generally select vitriol as the medium of erosion, such as the international standard determination of the resistance to sulfate of dense shaped refractory products "(ISO8890) and PRE /, grinding fine particles to 0.63 ~ 0.80 mm, and then measure its quality loss, put it in the vitriol with mass fraction of 70%, finally boil 6 h.
- Q: what kind of fireproof materials is used for high rise buildings?
- First, fire resistance steel door: in the general real estate, developer uses more of fire resistance steel door. The mid-low-end doors are the earliest products and mostly widely used with longer servce time. The disadvantages are corrosions, thus it will rust, fade after being used for a while, and will affect the overall appearance. Styling lines are hard, not matching well with modern home decorative styles. Second, the stainless steel fire doors: anti-theft performance ,durable, stronger security. Compared to the general iron or mixed iron and steel security doors, stainless steel doors never rust and most importantly its uniqueness in addition to lasting bright color. Disadvantages: Stainless steel security doors are mostly silver, giving us dull feelings by seeing its appearance and color, lack of coordination. Third, glass fire door: high quality fire glass doors. recent years have seen wide application in office buildings and some high end public place, less in individual users. Compared to the current categories of timber, fire glass door is not only simple and luxury and durable.
- Q: How long is the fire resistance time of the AAAfire resistance rolling shutter door?
- How long is the fire resistance time of the AAA fire resistance rolling shutter door?
- Q: Does refractory belong to stone, building materials or other?
- Refractories belong to organic non-metallic materials.
- Q: what is the common materials for home fireproofing material?
- 1, lumber core 2,decoration panel 3 , plywood 4 density board 5,chipboard 6 fireproof?panel, 7.gypsum board Hope to adopt my opinion
- Q: Which one is better, fire-resistant wood or steel?
- From the aspect of low-carbon and environment protection, the steel and timber structures are both OK, they are both renewable resources, the steel can be recycled and melt down again and wood can continue to be planted. Fireproof board Fireproof board is a refractory material used for surface decoration. It is widely used in interior decoration, furniture, kitchen cabinets, laboratory tables, walls, and other fields.
- Q: Can anyone tell me what is a high alumina refractory?
- Refractories refer to a class of inorganic non-metallic materials whose refractoriness are no less than 1580 ℃. Refractoriness is the Celsius temperature when cone-shaped samples can resist high temperature without softening and melting down in the absence of a load. But it is not accurate to define refractory merely by judging that whether the refractoriness is no less than 1580 ℃. Currently, the materials whose physical and chemical properties allow them to be used in high temperature environments are called refractories. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, power and so on, among which the metallurgical industry is the largest demander in this regard, accounting for 50% to 60% of total output. Hope it will help you out!
- Q: Does anyone know the fire endurance of steel stud partition?
- Indeed ① Dragon Brand gypsum board fire-resistant partition: Its fireproofing extreme time is 4 hours, suitable for firewalls of a variety of public buildings, public exit passageway and other partitions, which meets the first level of fire protection standard ② fireproofing and pressure-resistant partition: Refers to the partition which can withstand momentary gas shocks of over 1200pa , mianly used for the room partition with inert gas fire-fighting needs, such as equipment rooms. The pressure-resistant degree of fireproofing and pressure-resistant partition of Beixin Building Materials can be up to 4800Pa, especially suitable for high-rise fireproofing.
- Q: How to distinguish the fire resistant level of construction materials?
- Building materials fire resistant level is divided into four levels, among which the first level is the highest, with strongest fire resistance; fourth level is the lowest with weakest fire resistance. Fire resistance level of buildings depends on combustion performance and fire endurance of the building components. The building components refer to a series of basic components such as the building walls, foundations, beams, columns, floors, stairs, ceiling, etc.
