Products Description

Needled-fiber blanket,made from common , high pure,high aluminium and zirconium alumina silicate

fiber bulk produced by blowing fiber forming technology, has undergone several processes including

needling , thermal forming, vertical and transverse slitting and rolling.

Needled-fiber blanket have even texture and smooth surface . Long fiber and low ball sediment,which

comprehensively improves the inter-weaving degree, delamination resistance,performance , wind

erosion resistance , flexibility and tensile strength of fiber. Therefore , the application property of

needled blankets is improved and material loss is cut down.

Typical Application

1.Industrial furnace, heating devices, high temperature pipe wall linings.

2.High temperature boilers, steam turbine and nuclear power thermal insulation.

3.Chemical industrial high-temperature reaction equipment and heating equipment wall linings.

4.High building fireproof and thermal insulation.

5.Furnace door and roof thermal insulation.

White Ceramic Fiber Blanket

Q:Would you like to know if there are any enterprises in Mianyang that need fire-resistant materials?: I only know that the Stone Town Youxian district with a fire stopping collar.

Q:What are the uses of refractory materials of glass furnace?: crown--high-purity silica bricks; wall--melting end 41# fused zirconia corundum bricks with no shrinkages(41% of zirconium, similarly hereinafter), cooling end 33# fused zirconia corundum bricks with no shrinkages; bottom--33# fused zirconia corundum bricks(with shrinkages); breastwork--33# fused zirconia corundum bricks(with shrinkages); port--33# fused zirconia corundum bricks(with shrinkages); regenerator chamber--the upper part is for magnesite-chrome bricks, the bottom part is for high-duty fireclay bricks; checker--the upper part is for high purity magnesia bricks, and the bottom part is for magnesite-chrome bricks; flue--clay bricks. This is the best configuration. If the funds are limited, the configuration can be lowered, for example, the wall will be changed to 38 #......

Q:What do we mean by saying that a ladle cover knots, elbow knots, blowpipe knots in refractory materials? What is the “knot”?: Blowpipe is also the construction of unshaped refractory materials. Refractory material for ladle cover is light weight heat insulation refractory material. What you said that the construction of bend out refractory materials in some steel mills called "knot".

Q:The primary problem, does the gas permeable brick is fired refractory bricks(refractory) ?: gas permeable brick have two types:built-in type and external mounted type. the built-in gas permeable brick and the external mounted gas permeable brick are usually made by fire burning, and small part of bricks are made by the low temperature heat.

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:What are the qualifications of refractory industry?: Certificate for production and sale is needed, just like the certificate for other products.

Q:What thickness is needed of the ultra-thin fireproof paint with a fireproof time of 2.5 hours?: Fireproof of steel components can adopt outsourcing concrete (or laying bricks method), fireproof coatings, fire prevention board coated and composite structure. Anti-firing plate can be divided into the fire protection lamella thickness plate and thin plate. Fire protection lamella thickness plate is of 20 ~ 50 mm. There are mainly calcium silicate and decayed stone of fire prevention board fire board, main varieties KB board, CF board; Fire sheet thickness is between 6 to 15 mm and the main varieties have short fiber reinforced cement pressure plate, fiber reinforced ordinary calcium silicate board and glass cloth reinforced inorganic plate. I hope you can be satisfied.

Q:What do refractory materials include?: What refractories are included? Refractories include AZS brick, corundum brick, direct-bonded?magnesia-chrome, carborundum brick, silicon nitride bonded silicon carbide brick, non-oxide refractory materials such as nitride, silicides, sulfides, borides and carbides, oxidation calcium, chromium oxide, aluminum oxide, magnesium oxide and beryllium oxide.

Q:Does anyone know about the classification standards of B2-level fireproof and thermal insulation materials?: The fire-resistant differences of B1- and B2-level extruded insulation boards are as follow: B1-level materials will be smothered as soon as staying away from fire, namely, they will be extinguished after leaving fire, or be put out in 10 seconds. B2-level materials will be in low-grade combustion, namely, the fire will not get wilder, and drippings will not ignite the filter paper. I hope my answer can help you!

Q:What is refractory cement?: The introduction of properties and chemical composition of refractory cement. Refractory cement usually refers to the cement with calcium?aluminate as the mian compopnent. Refractory cement is a monolithic refractory. It is in particular a basic binder of castable refractory. Its chemical composition is mainly Al2O3 and CaO, and some contain a considerable number of Fe2O3 and SiO2.
