FAQ

Does anyone know fire-proof material of fireproof wooden door?

Because the timber of fireproof wooden door has gone through fire retardant 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. Spraying method and soaking method are generally used for timber surfaces which are no longer going through planing process, and thin plate fire retardant treatment, whose thickness is less than 10mm . Vacuum method and vacuum-pressure method have excellent flame retardant efficiency, but their equipment are expensive. Fireproof wooden door refers to the door whose fire endurance of door frames, skeleton of the door leaf, door panels made of timber or timber work reaches the provisions of "GB50045-95 design of tall buildings for fire protection".

What is the the best ratio of mortar in refractory cement?

Specifical proportions are as following: 42.5R cement is 425 rapid hardening cement. Using the 425 cement to compound the mortar. The reducion of cement will naturally impact the workability of the mortar. The mix design standard of the mortar specifies the minimum amount of cement is not less than 200kg / m3. If it is composite mortar, and the strength and workability can be ensured, it is Ok to use 425 to compound. You can look for instructions of mixing proportion of mortar online as a reference.

Does refractory belong to metallurgical auxiliary materials?

Refractory includes metallurgical auxiliary materials.

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?

The variety of refractory materials for intermediate frequency furnace is mainly made of aluminum and silicon, both shaped and unshaped refractory materials are available. I have no ideas what you said boric acid, I’ve never seen that boric acid was used as an additive.

Who knows what kind of material the fire-proof plate use, and is it good?

It is the decorative board made by adopting silicious material or calcareous material as the main raw material, and blending them with certain proportion of fibrous material, lightweight?aggregate, adhesive and chemical?additive before steam pressing. It is a kind of new material and more and more frequently used currently not only for it is fireproof. Construction of the fire-proof plate has higher requirements on the adhesive, and the price of the fire-proof plate with better quality is more expensive than that of the decoration panel. The thickness of the fire-proof plate is generally 0.8mm, 1mm, and 1.2mm. So it is the best material for making cupboards.

Urgently!! Refractory problems, online, etc.

I feel that is the coating package, the coating of water is too large, the retaining wall in fused powder hydrated, can not produce strength under high temperature. What do you think?

who knows the uses of refratories?

Of course, the role of the refractory material is fireproof, generally used in large buildings. It can reduce casualties and economic losses caused by the fire. it also can be used on the chemical instruments. ! !

how to use boiler fireclay

Boiler refractory, diluted with water to touch the places where needed, can be used after high temperature baking.
