 Description of High Alumina Refractory Cement  


Products

Calcium Aluminate Cement /High Alumina Cement CA-50

Applications

1,As binders calcium aluminates cement are used in concretes and mortars for specialised applications

 for their properties of resistance to corrosion, abrasion and heat combined

with rapid hardening and the ease of controlling grading variations.
Calcium aluminate cements are also used in combination with other fine components. Hydraulic binders

 with new properties are then obtained. In this way, aluminates act as both a complex hydraulic binder and

 a mineral reagent interacting with the other components in the mix.

2,As reagents, calcium aluminates are found in non-hydraulic systems. This is the case in metallurgical treatments

 (iron and steel industry, foundry) where specific grades of calcium aluminate are used for their low-temperature

 melting properties and for trapping molten metal impurities.

 

 

Features

1,Very low mixing-water requirement

2,Very high purity

3,High product consistency

4,High cold and sintered strength

5,Very tight specifications of setting times

Q:What's the material of electrical fire prevention board?
Industrial electrical fire prevention board is mainly aimed at fire protection and thermal insulation. Iron plate is electrically conductive with good thermal conductivity, which will cause the result that the equipment is not insulated and suffers larger superheating surface! ! ! !
Q:what is best for making refractory insulation for Blast furnace, hot stove.
High dimensional insulating blanket.
Q:How many external wall thermal insulation fireproof material are there
Inorganic active wall thermal insulation materials, cement foam thermal insulation board, glazed hollow bead insulation mortar, rock wool plate, glass wool plate etc., if used for external wall thermal insulation, rock wool board more frequently used.
Q:What kinds of fireproof and fire retardant materials are there?
recommend new Nano-insulation refractory insulation material Aerogel material, which consists of 99% pores of different sizes. it is not only the lightest and the most remarkable insualting material, but also having hydrophobic porous particles. 1830s invention.It has low thermal conductivity,not susceptibale to electrical, thermal and impact of sound with strong physical stability. It is a good insulator, but also has a strong impact resistance, three times the weight of the same volume of air. It is not heavy and can be used as heat insualting materials,buffer materials, sound proof materials. It has attracted world attention and will be widely used in the future. Aerogel (Aerogel) features: Nontoxic to humans, insoluble in water, no burning, odorless, the world's lightest, low thermal conductivity. Aerogel heat shield is a new industrial insulation products. New products based on nanotechnology materials Aerogel, Aerogel materials in foreign countries has been widely used. We find it a lot better than the traditional insulation materials. To this end, the company introduced the product to China to open the Chinese market and import the best insualting materials to oil refining, electric power, shipbuilding, chemical, industrial pipelines, aerospace, machinery and equipment industries.
Q:Who knows the refractoriness of high temperature lightweight firebricks?
Hefei Jiu oak decor help you answer; the biggest feature is refractory: refractoriness 700.
Q:The structure of refractory material
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:What are the materials of class A fire resistant window?
Environmentally friendily, non-poisoned non-peculiar smell, non-radioactive; non-combustible, fireproof, moisture-proof, corrosion-resistant; easy to operate, lightweight, high strength, themal insulation, sound insulation; able to be cut, planed, sawed and carved. It also meets GB8624 -2006A1 level non-combustible standards. Lightweight, high strength, anti-aging, corrosion resistance; meeting the GB / T20285-2006 Opium (AQ1) safety and environmentally friendly products; Foamed fire door core board specifications: 2100 × 900 × (26 ~ 65) mm; 2050 × 850 × (26-65), and many other specifications. I hope my answer can help you.
Q:What level is the rock wool board fireproofing material ?
The fire rating classification is a provision for all insulation materials, rather than to separately divide rock wool. Determine the value of the material fire rating according to the relevant test items of 8624. As the rock wool is made from basalt fusion, so it is the level A non-combustible material. And those we usually see are the mineral cotton and glass wool, with its refractory temperature lower than the rock wool's. Rock wool board is now mainly used in wall insulation, which is a level A fire insulation material.
Q:Does anyone know which materials belong to light fire resistant material?
Building board of lightweight fireproof partition material: 1, GRC lightweight partition material glass fiber reinforced concrete; it is a kind of fiber cement composite with alkali-resistant glass fiber as reinforced material and cement mortar as the base material . Aerated concrete block equipment foundation construction Its outstanding features are having good tensile, rapture strength and good toughness. This kind of material is particularly suitable for the production of ornament mould and the manifestation of strong texture. Compared with these external wall decorative materials, the biggest advantage of GRC material is to meet the individual needs of architects, completing the expression of various ornament moulds and skin textures. 2, fiber reinforced low alkalinity cement building plate. The standards stipulate the classification, raw materials, technical requirements, test methods, inspection rules, packaging, labeling, transport and storage of the fiber reinforced low alkalinity cement building plate.
