Application :
High alumina refractory cement CA50,have passed the ISO international quality certifify.According to the different content of Al2O3,they can have totally foue types:CA50,CA60,CA70 and CA80.They have the advantage of longer setting time,can resist high temprature,better stability in air,rapidly strength,no addivity and suitable for confect all kinds of castables and low cement refractory castables,refractory concrete,ramming mixes, gunning mixes and manmade marble bricks etc.
- Q: Where is the production of refractory manganese alloy manufacturers? Manganese is recommended between 63 and 70!

- Q: Does anyone know what kind of light fireproof materials are there?
- 二, 1, Gypsum plaster board With the building plaster as main raw material, gypsum plaster board is a kind of processed plate made by a special board for protective with an addition of additives and fibers as board core. Gypsum plaster board is characterized by light weight, sound insulation, heat insulation, strong processing performance and simple construction method. 2, Gypsum block Gypsum block is a kind of lightweight building gypsum product which is mainly made of building gypsum, and by adding water, stirring, casting and drying. During the process, , the fiber reinforced materials or light aggregates are allowed in, and the foaming agent can also be added. It has many advantages, such as sound insulation and fire prevention, convenient construction and so on. It is a kind of new and healthy wall material which produces low carbon, enhances environmental protection, and caters to the the times. 3, Fly ash brick is a new type of wall material, and bulk density is one of the main technical indexes. The weight of bulk density can be controlled according to the need of construction and adjustment of technical formula. The dry bulk density of the fly ash brick is about 1540 to 1640 kg / m 3, slightly lighter than the clay brick (1601800 kg /m 3). The flexural and compressive strength of fly ash brick is mainly determined by the production process, the formula and the hydrothermal synthesis reaction mode as well as the need of construction. According to the standards of architectural material industry (JC239 - 2001) released by People's Republic of China, the average value of the flexural strength is 2.5 ~ 6.2Mpa, compressive strength is between 10 ~ 30Mpa. I hope this will be helpful to you
- Q: How many types of special refractories are there?
- Metal ceramics, high temperature coatings, high temperature fiber and other reinforced materials
- Q: What's the function of aluminium dihydrogen phosphate on the refractories?
- Mainly used for binder of high-temperature furnace refractory. Characteristics of liquid aluminum dihydrogen phosphate, castable. solid used for refractory spraying coating, chamotte, ceramic construction, which has high break resistance after being dried in 350-500 ° C, phosphate bricks. Characteristics of the solid aluminum dihydrogen phosphate, binding agent used for castable and casting industry: together with the refractory aggregate, ramming mixes at room temperature: Easy to mix, crush resistance, hydration resistance, chamotte, will not become soft even if soaked or boiling in water, molding. Liquid use refractory spraying coating, mainly used for corundum, chrome corundum water gap in refractory industry. The production of chrome aluminum zirconium corundum brick for water-coal-slurry gasifier is especially suitable for site construction applications mainly used for the electrical industry, high-temperature kiln and furnace, hardener, after mixing between 90-110 ° C for 4-24 hours at a constant temperature, forming strong bonding strength, electrical insulation, heat treatment resistance furnace
- Q: What kind of materials can be tested their electrical resistivity in the current refractory industry?
- Graphite, Magnesium Oxide, and alumina are all feasible.
- Q: what's the classification of fireproof materials?
- Fireproof materials are used in construction, in various forms and it has played an absolute role in modern fireproofing, common fireproofing materials include fireproof?panel, fire door, fireproofing glass, fire?retardant?coating, fireproof bag,etc Or the material itself has a high temperature resistance, heat-resistant, flame-retardant properties. Most of them are used for the construction industry.
- Q: How should fireproof building materials be ranked?
- Division of fire-proof grade of buildings is one of the most basic measures in the fire-fighting technology and measures of buildings. According to our national code of building design, fire-proof grade of buildings are classified into four levels of first, second, third and fourth, of which the first level is the highest in fire resistance and the fourth level is lowest in fire resistance. Fire resistance rating of buildings depends on the combustion performance and fire endurance of the building component. The so-called building component refers to the walls, foundations, beams, pillars, floors, stairs, ceilings, etc.
- Q: Refractories for iron-making blast furnace?
- This question is too professional - as far as I know, there are blast furnace noumenon bricklaying - trough slag runner fire-resistant model ~ main channel carbon rod ~ ramming mixes ~ ~ I do not know the specific details.
- Q: how does the fire endurance of first rate fire resistant window?
- class A window not less than 1.5 hours, class B window not less than 1 hours, Class C window not less than 0.5 hours.
- Q: Are there any differences between insulation and refractory materials ?
- I will explain to you in a simple way. Refractory materials can resist more than 1200 degrees, some of which are not insulation materials, such as firebricks, which can directly contact with heat source, has little insulation effect. Ceramic fiber, high silica, etc. are all refractory materials which can insulate. Insulation materials with poor performance usually is lower than 800 degrees, which have large thermal resistance, and low thermal conductivity, high porosity. Thus they reduce the thermal loss. To put it simply, insulation materials store most of the heat and only let a small part of heat lose through the air, thus the heat has been isolated. Glass fiber, rock wool, flexible material for thermal insulation, etc. I hope you can understand it.
