Q:What are the materials of white firebricks?
White refractory materials are generally divided into two types, namely, unshaped refractory materials and shaped refractory materials. Unshaped refractory materials, also called castables, is a mix of powdery particles of many aggregates and one or multiple adhesives. They must be stirred well with one or multiple liquids when in use, which has a strong liquidity. Unshaped refractory materials generally refers to firebricks. They have standard rules about their shapes and can also be processed temporarily as needed.
Q:what are the requirements of fireproofing material?
The producing process of fire and moth proof wood: firstly, put general wooden materials into solution with calcium, aluminum and other cations, then soak it into the solution with phosphate radical, silicate and other anions. Thus, the two ions will be carried out chemical reaction in the wood, forming a ceramic-like material, and intimately fill the voids of cells, so that the wood has the fireproofing and mothproof properties.
Q:Refractory factory grinding brick dust harmful to the body?
The effect is very large and belongs to lung disease.
Q:What is refractory cement?
How to use exactly refractory cement? Someone professional advised me to buy this cement. Does it differ a lot from common cement? Is refractory cement expensive?
Q:Is fireclay poisonous?
Refractory materials are typically oxides, alumina, magnesium oxide and aluminate cement and etc, which are non-toxic.
Q:I want to know what is the slim in the refractory bricks
Where are you from, I can introduce to you
Q:Technical scheme of refractory for refuse incinerator
The equipment shall be subject to the construction of refractory materials after acceptance by the relevant personnel.The furnace body is divided into two parts: the construction of a refractory material are respectively first half brick masonry, steel shell near the first building refractory clay brick masonry to both sides from the middle to the lowest height semicircle, clay brick masonry completed all started after graphite brick masonry, also to the semicircle; after the completion of the second half part of all the brick masonry, began laying it on the semicircle: first set semicircular pattern suggested pattern width is 1 ~ 2 brick masonry first width, graphite brick, clay brick masonry and masonry, from both sides to the middle, laying a piece of graphite brick masonry clay brick.
Q:What is the main material of fireproof wooden door?
Fireproof door is an important part of fire-fighting apparatus and society fire prevention, so the quality and use of fireproof door is the key to the success of the fire prevention. Some customers don't know clearly that whether the fireproof door should install a door closer. Today I specially read the explanation of relevant state departments for fireproof door, in the explanation in 5.3.3, fireproof door should be installed fireproof door closer or set, so that normally open fireproof door can automatically close close-door device of the door leaf (except for the use of special parts, such as pipe shaft doors, etc.) in the event of a fire. In other words, except for some special parts which don't need to be installed door closer, such as pipe shaft doors, other parts are required to install fireproof door closer.
Q:Procedures for producing common refractory materials?
The general procedures of producing refractory materials include calcination of raw materials, selection of raw material , crushing, grinding, screening, mixing, ageing mixture, molding, drying, burning and etc. At present, the refractory factory usually purchases the calcined clinker, so the calcination of raw material is no longer a consideration of common refractory plants.
