refractory grade size 1-3mm calcined bauxite

1. Calcined Bauxite 1-3mm brief introduction:

Calcined bauxite is a mixture of minerals that contain various concentrations of hydrated

aluminum oxides as well as impurities. The primary ore minerals are gibbsite (alumina tri-hydrate), boehmite and diaspore (alumina monohydrates).

Q:which kind of fire?bulkhead is better?: General business fire endurance of two products are 3 hours. Organic fire bulkhead's main ingredient is organic material, which can be used in anti-corrosion and fireproofing cable tray. Inorganic fire?bulkhead's main ingredient is inorganic material, which mianly play a role of fireproofing. It's main ingredient is inorganic material, so it can't be used in acidproof and alkali resistant projects. Of course, the price of same amount organic fire?bulkhead in general is more expensive than the inorganic fire?bulkhead.

Q:What types does refractory floor include?: The categories of refractory are: 1. the best overall performance stone flooring (waterproof, fire retardant) The full name is microcrystalline stone flooring. It is a high-performance waterproof and fire-retardant environmental wood floor synthesized with high and new technology. Its unique raw material is ground calcium carbonate micro-crystalline polymer stone with natural resin and other twenty more imported spreadings. It is formed by refining with high temperature (300 degree centigrade) and high pressure (9,000kg). It is an environmental healthing high-performance material. Its product is innocuous and unpoisonous, and won't age, deform, fade while it is fire retardant, waterproof, maintenance-free and quality, so it is an inevitable repalcement with traditional wood floor. This product has been confirmed as national key promotion program. 2. Wear-resistant composite solid wood floor It is also known as super wear-resistant multi-layer solid wood floor. First stiffening layer surface (based on inorganic materials and steel fibers for paper impregnated with thermosetting amino resin with solid wood or plywood blockboard substrate surface as a combination of facing layer), the front is wear-resistant layer, and the back is balance layer. Thtough hot pressing, it is a grooved and tongued floor, a new impregnated paper laminate floor. It also has the same wear-resistant quality as laminate floor, beauty and foot feel as solid wood floor, stable structure as solid wood composite floor, etc. 3. Waterproof plastic wood floor Plastic wood (also known as "wood plastic" or "plastic wood") composites, and the English name is WOOD-PLASTIC-COMPOSITES, WPC for short.

Q:What is refractory aggregate?: It includes two categories: coarse aggregate and fine aggregate.

Q:can slag tailings be used to be the base materials of refractory materials ?: the rest of it can be used as refractory additives. the scale currently used clay bricks to make high-temperature liquid. It is easy to produce large amounts of liquid because of the high iron content, instead of its refractoriness. But it can be used as refractory minaralizer.

Q:what's the fire endurance of fireproof?panel?: Fire endurance of fireproof?panel is 3 hours, for example, 12 mm non-asbestos fiber reinforced calcium silicate board, fireproof?panel, two single 75 keel. through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 3 hours. Fireproof board, also called fire endurance board, scientific name is thermosetting resin impregnated paper laminated wood.

Q:What is the requirement of refractory concrete for raw materials? What is the main principle of commercial mixing station?: Commodity concrete stations can not be produced in general, and are made by professional fire resistant concrete manufacturers.

Q:What brands are the best in the A-level refractory materials?: This is two descriptions, glass wool refers to the texture of insulation materials, and A-lever refers to the combustion performance of fireproof materials. Generally the glass wool can achieve A-level combustion performance, unless you have add too many other combustible materials to it.

Q:Ask some questions about refractories: Application: it is suitable for blast furnace tapping system.

Q:which kind of material is chosen for fireproofing window?: Firstly, fireproofing window glass must be tempered, ordinary glass won't play a role of fireproofing, and fireproofing window fan is fixed, can't be open, if you can open it, it won't play a role of fireproofing. And you can ask the property to provide texture report of fireproofing windows, fireproof material stipulated by our national fire protection laws and regulations must have fireproofing inspection reports, there must be. and fire window glass should have a fireproofing sign. The main role of fireproofing window is to isolate the fire, and play a role of fireproofing and escaping, avoid the fire quickly spread in.

Q:how long is the fire endurance of plasterboard?: Plasterboard is non-flammable B1 level products. There are introductions in Fireproof Specification of National Standard Building Interior Decoration Design. Plaster board mounted on steel stud can be used as A level decoration materials. In accordance with the national fire safety rules on fire durance of walls and ceilings and other components, we can not simply say whether a piece of gypsum board can meet the requirements. In GB "gypsum board" it clearly states: Fireproof plasterboard can endure fire longer than 20minutes. Wherein Dragon brand fire-resistant gypsum board can endure fire longer than 40 mintues. Gypsum board is comprised of dry wall, steel stud and various auxiliary materials. the fireproof performance of the gypsum board system is relevant to the type, quality , layers of the gypsum board, quality of keel and installations, whether the rock wool is filled and its unit weight, the treatment of seaming and some minor joints.
