 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 fire?retardant material of roller shutter fire resistance door ?
Fire resistant rolling shutter door is generally filled with aluminum silicate fiber cotton inside.
Q: Why the refractories should be waterproof and wetproof
The binding agent of many raw materials is water-soluble. It will be useless when meeting water.
Q: Which brand of thermal insulating refractory is good?
Brands of thermal insulating refractory: 1, Armaflex(German brand). Manufacturer: Armacell thermal insulation materials (Guangzhou) Co., Ltd, Armacell thermal insulation materials (Suzhou) Co., Ltd. 2, Durkflex (American brand) Manufacturer: Durkee (Guangzhou) thermal?insulation?material Co., Ltd. Durkee (Wuhan) thermal?insulation?material Co., Ltd. 3, Aeroflex (Thailand Brand) Manufacturer: Aeroflex Polymer Technology (Shanghai) Co., Ltd.
Q: What kinds of refractory will be used in kiln of sintering ceramics?
Porcelain has many classes, including acid, alkaline and neutral materials.
Q: How much is the duration of fire resistance of the porous brick shale?
It depends on its formula since the highest temperature varies from formula. For example, the temperature of common bricks is 900℃, if the lime in it accounts for most part, then the temperature could reach 1050℃; if coal ash accounts for over 40%--50%, then the temperature could amount 1050℃--1150℃, I hope my answer will help you a lot.
Q: What is the concept of lightweight refractory material?
Lightweight refractory material has high porosity, mechanical strength and erosion resistance. Compared with normal refractory bricks, it is a kind of refractory material with large volume shrinkage in high temperature, low thermal conductivity and small bulk density. It is used as thermal insulation material in industrial furnace and other thermal equipments. It has poor wear resistancel.
Q: Is aluminium oxide refractory material?
Aluminium oxide with 2030?C melting?point is a kind of good refractory material. It can be used as analytical reagent, dehydration and adsorbing?material of organic solvent, catalyst of organic reaction, abraser,polishing agent, raw material of aluminum smelting technology and refractory material. Hope it is helpful to you.
Q: How many types of fire-resistant material?
1. Acid fire-resistant material refers to one with more than 93% SiO2. It is featured by resistance to the corrosion of acidic slag ad high temperature and easy to react with alkaline molten slag. 2. Alkaline refractory material generally refers to one with magnesium oxide or magnesium oxide and calcium oxide as the main component. It has high refractoriness and strong resistance to basic slag. 3. Silicate aluminum refractory material refers to one with SiO2, Al2O3 as the main component. According to the content of Al2O, it can be divided into three categories: half siliceous (15-30% Al2O3), clay (Al2O3 30 ~ 48%), high aluminum (more than 48% of Al2O3). 4. Fused cast refractory material refers to shaped refractory products made by high temperature melting and casting.
Q: how to classify the fireproofing material levels A1 A2 B1?
their classification is shown specifically in Fireproof? Specification of Building Interior Decoration?Design GB 50222-95 appendix A, flammability,inflammability materials, flame retardency, noninflammability: combustion performance of A, B3, B2, B1 materials are divided into
Q: What kinds of fireproof materials does the safe use?
The fireproof materials of the safe, cement foam. It is often said recently that the safes with cement inside are bad. Actually, it is not like this. Chemical means are taken to make the cement inside safes rise like a leaven dough so as to achieve good insulation. The principle is the cement foam. Fireproof safes with such techniques have good performance in terms of fireproofing and anti-theft. The manufacturing processes of this fireproof safe are highly technical, some safes with poor techniques have problems in quality. Here are some data of the foam cement.
