$Refractory For Furnace Silica Fire Brick$

Q: The fire prevention board line is made of what material?: Crural line: wooden, in the market, there are sjoiner woodblock, peach wood and artificial engraving. The second classification is stone and the most used one is the marble graved or ceramics well-made one is taken as the first choise. Its price is a little bit expensive than the wooden one, but also a suitable choise. Condole supports: It has various category. The general furniture choose plaster and anti-firing plate and the other also have a choice of steel. You can make a suitable choice according to the need. If it is contracting project, it depends on your project specific plan and funds plan. In a word, beauty and harmony should be given priority since it is the source of design.

Q: How long is the duration of fire resistance of hollow glass magnesium board: Glass magnesium board is non-combustible board with excellent fire resistance ability, the continuous burning time of flame is 0, non-combustible at 800℃, no flame at 1200℃, achieving the highest level of fire retardant level A1; Partition System cooperated with high-quality keel can endure fire for more than 3 hours. In the process of combustion, a large amount of heat energy can be absorbed, and the temperature of the surrounding environment will be delayed.

Q: what's the classification of fireproof and thermal inuslation matertial?: Inorganic thermal insulation material can do it, such as glass wool,rock wool,foam glass,etc. phenolic foam materials in organic foam material is special. phenolic foam not only has good thermal insulation properties but also can be composited with steel plate and other materials, A class thermal insulation materials that reach A class combustion performance include: rock (mine) wool, foam glass, EVB, etc. thermal insulation materials with A class combustion performance mainly include: phenolic aldehyde,gelatine powder polyphenyl granule, etc. thermal insulation material of fire barrier zone can use rock (mine) wool, foam glass, EVB and other materials with A class combustion performance.

Q: Where is the sizing nozzle for refractories? Just enter the line, master into!: This is the use of steel tapping water procedures inside!!

Q: What refractories are accessible with ease in daily life? This material is suitable as a disposable mold and crucible for melting brass.: There are many refractories in daily life. Such as the lining of furnace! And refractory cotton ... If you want to melt brass, you need to resort to professionals! It's rare in daily life to find out those molds that can be made by ourselves. You can buy a corundum crucible in the neighbouring laboratory equipment market! Remember that brasses' melting point is at above1000 degrees, so the material must have refractoriess of 1000 degrees.

Q: The performance of refractory material: The mechanical properties of refractory material include withstand voltage strength. The structure properties of the refractory materials include porosity, bulk density, such as thermal emission rate. The physical properties of the refractory materials include temperature conductivity structure performance, wear resistance, hiphotos, electrical conductivity, creep, the hydration resistance, adhesive strength.

Q: Does anyone know fire-proof material of fireproof wooden door?: Fireproof wooden door goes through the flame treatment, so it can prevent fire. Its principle: Fire-retardant treated timber has become flame retardant material itself and its fire endurance has increased. The commonly used method of fire retardant treatment for timber including: Spraying method, soaking method, boiling method, vacuum method, vacuum-pressure method.

Q: What thickness is needed of the ultra-thin fireproof paint with a fireproof time of 2.5 hours?: The thickness of steel structure fire retardant coating hasn't been regulated in the steel structure application specification (CECS24:90). The above thickness refers to a certain thickness that must (at least) achieve a certain time of the fire resistance. The thickness of fire-retardant coating in engineering is generally determined according to factory inspection report. We use thin steel structure fire retardant coating: 2.5 hours' fire resistance with the thickness of 4.9 mm; 2.0 hours' fire resistance with the thickness of 3.5 mm; 1.5 hours' fire resistance with the thickness of 1.75 mm; 1.0 hours' fire resistance with thickness of 1.17 mm. I hope I can help you.

Q: What is shapeless refractory with high performance?: The popular ones are: Non-cement fine powder bonded castable is a functional refractory castable with nano material introduced.
