Q: What's the fire?retardant material of roller shutter fire resistance door ?
Fire resistant rolling shutter door is generally filled with aluminum silicate fiber cotton inside.
Q: Is there any difference between insulating bricks and refractory bricks? Are there any professional refractories factories that are reliable in the quality and quality of these irritated materials?
Seven characteristics of insulating brick:Insulation and heat insulation: effectively reduce energy consumption.Fire prevention: up to national standard or class A.Clean and environmental protection: no two pollution will be caused by air.Per square metre weighs only about 1.4 kilograms, reduce the burden of building.Simple production: completely break through the traditional process, greatly shorten the construction cycle.Beautiful: can be modulated into a variety of colors, suitable for Ming outfit.Durable: long service life.
Q: What kind of material is refractory fiber?
Refractory fiber, also known as ceramic fiber, is fibrous thermal insulation refractory. It has the characteristics of ordinary fibers, such as softness, flexibility, having a certain tensile strength. And it can be further processed into a variety of products such as paper, wire, rope, tape, blankets and felts.
Q: How long usually will the A-level fireproof materials prevent the flame?
A-level fireproof materials refer to the materials which are made of non-combustible materials, it is a different concept from fire resistance. non-combustible elements: Components are made of non-combustible materials. Non-combustible materials refer to materials that will not burst into flame, and burn as well as be carbonized when affected by fire and high temperature in the air. Fire resistance: Having a fire resistance test on any building components -----according to the standard time-temperature curve. This period starts from the time when affected by fire and ends up with losing the ability to support or to insulate fire or the integrity of the components. It can be expressed in hours.
Q: What are the fire resistances of grc partition panels?
It's ok, calcium silicate itself is a non-combustible material. Light partition walls with keels has the longest fire resistance of 4 hours according to the thickness of the walls. We can talk about it in detail.
Q: What kind of refractory materials are used in the intermediate frequency furnace?The domestic boric acid can be used as a lining?, how much is the rate?
Acid, neutral, basic and composite materials are used in intermediate frequency furnace. Domestic boric acid is practicable. The ratio is to determined combined with material, steel (iron) species, smelting temperature, current and other factors
Q: Who knows the texture of fire-proof wooden door material?
The so-called fire doors are only posted a layer of fireproof material. Door selection still depends on the timber inside. The simplest way is to see the weight value, fireproof material layer, and they are generally paint-free doors. with fireproofing function..
Q: Who knows how many poured refactory material are there?
Casting refractory material, refractory material used often are AZS brick, corundum brick, direct bonding magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide brick, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, aluminum oxide, magnesium oxide, beryllium oxide and other refractory materials.
Q: Is it necessary for the frame of glass fireproof door to be crammed with fire-proof material?
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.
