Q:For refractory knowledge. What is the ratio of clay ramming mass?
Soil aggregates, dispersing agent, water reducing agent, plasticizer, binding agent and powder! ~ Bone meal feed approximately 6, OK
Q:How to divide the materials according to the National Fireproofing Material Standard?
2,generally, the external wall thermal insulation materials is divided in accordance with fire rating: 1, the class A combustion performance of insulation materials : inorganic fiber spray coating, glass wool, foam glass, foamed ceramics, rock wool, foam cement, hole-closed perlite ect.. 2) class B1 combustion performance of thermal insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde, gelatine powder polyphenyl granule, etc. 3) combustion performance of class B2 insulation material: molding polystyrene board(EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. I hope it will be helpful for you
Q:Who knows about the criteria of fireproof and thermal insulation materials?
The standards of fireproof and thermal insulation material. 1. the height of buildings is greater than or equal to 100 m, the combustion performance of thermal insulation materials should be A-level; 2. the height of buildings is greater than or equal 60 m but less than 100 m, the combustion performance of thermal insulation materials should be no less than B2-level. When using B2-level thermal insulation materials, fire barrier zone should be set in each floor; 3. the height of buildings is greater than or equal to 24 m but less than 60 m, the combustion performance of thermal insulation materials should be no less than B2-level. When using B2-level thermal insulation materials, fire barrier zone should be set in every two floors; 4, the height of buildings is less than 24 m, the combustion performance of thermal insulation materials should be no less than B2-level. When using B2-level thermal insulation materials, fire barrier zone should be set in every three floors.
Q:The principle of choosing fire-resistant material in Thermal Energy and Power Engineering equipment.
Different thermal technology equipment has different operation condition and select different refractory material. We should take economical and practical as principle.
Q:Fefractory of aluminium oxide.
Do you mean the alumina hollow ball brick? We can exchange private messages in specific.
Q:What is the principal part of silicious refractory material
lightweight silica bricks, product with fused quartz, the silicon dioxide content is generally greater than 93%, including silica brick silicious refractory SiO2 as a main component of refractory products
Q:What is refractory?
Refractory materials are widely used in metallurgy, machinery manufacturing, chemical industry, petroleum, power and other industrial fields. It is an inorganic nonmetallic material mostly used in metallurgical industry with the minimum refractoriness of 1580 ℃, able to resist high temperature without softening (annealing). It accounts for 50% to 60% in total output. Refractoriness refers to refractory's ability to resist fire.
Q:Does the production of refractory belong to advanced technology?
It certainly is advanced technology as it is the new material.
Q:Who can tell me about the foundry refractory materials?
Such as: neutral, alkalic, acidic refractories. Of course, the raw materials of different materials are not the same. Such as: the magnesia-carbon bricks, basic refractory materials: magnesite(electric smelting, high-purity)+ crystalline flake graphite+ phenolic resin+ additive (aluminate or silicon powder or silicon carbide powder or high-temperature pitch) and so on.
Q:What refractories are accessible with ease in daily life?
Refractory mortar. Thermal insulation refractory materials include diatomite products, refractory castables, monolithic refractories, carborundum bricks, gun-mix refractories, semi-silica bricks, borides, beryllia, silicide, calcium oxide, high alumina refractory brick, refractory coatings, corundum bricks, fireclay bricks, silicon nitride bonded silicon carbide bricks, chromium hemitrioxide and other refractories. What refractories can be found mostly in the market? Common refractories. Common refractories include silica bricks. The mostly used unshaped refractories include fettling, ramming refractories, castable refractories, plastic refractories, refractory clay, gun-mix refractory, sling refractories, refractory coatings, lightweight refractory castables, stemming etc. The mostly used insulating refractories include diatomite products, asbestos products, insulation panels, etc. The mostly used special refractories include AZS bricks.
