Q:Why do magnesium oxide refractory bricks can be made into refractories?
The substance used in refractories must have the following characteristics and properties: 1, High stability: Anti-oxidation, anti-reduction and thermal decomposition; 2, High melting point of 2800 degree; 3, Low price. The magnesium oxide refractories have all these three characteristics and properties, particularlly in the aspects of melting point and stability .
Q:what's the detailed address of fireproof and thermal inuslation matertial market?
Detailed address of fire insulation materials market is as follows: A: Guangzhou Huatai building materials co., LTD. Address: Guangzhou Tianhe Chepo Road no. 10 B: Address of Donglong building materials market: Guangzhou Tianhe Taian North Road no. 7 C: Address of Huiya building materials trade market : Guangzhou Tianhe Sports West Road No. 109
Q:What is the biggest difference between refractory bricks and clay refractory bricks? Where can I find information on the refractory bricks?
You can look up knowledge manual of refractory material to find phosphatic material, etc. Xinjiang refractory bricks, castable refractory, refractory material, silicious, corundum and alumina-magnesia: High alumina and clay refractory bricks can be divided into
Q:What is the mechanism of the errosion of the iron to the refractories?
For example, the effect of the iron oxide: Mo corundum given temperature Fe2O3 solid solubility limit of the solid solution formed of corundum stone high solubility than the solid solution Mo Mo corundum lattice shape so Fe2O3Al2O3-SiO2-based material starts melting temperature of the system or the content of Al2O3 and Al2O3 / SiO2 ratio off Al2O3 / SiO2 & lt; 2.55 starting melting temperature of 1380 ℃ when Al2O3 / SiO2 & gt; 2.55 start melting temperature is increased 1460 ℃ and with its Al2O3 content increased gradually to increase the original atmosphere Fe2O3 original FeO off the solvent into the glass phase and the system starts melting temperature drops do not fall to 1240 ℃ 1380 ℃. Lower the melting point, increase the erosion, and reduce the life span.
Q:What occupational hazards should be detected in glass ceramic and refractories industry?
Q:What characteristics do A grade external wall fireproofing material have?
1. Save space and reduce costs; 2. Fireproofing, green and environmental protection; 3. Waterproofing; 4. Sound insulation; 5. Thermal insulation; 6. Install easily and shorten the construction period; 7. High safety performance.
Q:Does the aluminum silicate fiber can be used outdoors? If not, what other refractories can be used outdoors?
Q:How long can gypsum board endure fire?
Fire endurance refers to the fire-resistent limit of the whole system of light-gauge steel structure coupled with gypsum. It does nor merely refers to gypsum board. Fire endurance of the common gypsum board with the thickness of 9.5mm keeps 1.5 hours. Those gypsum board with the thickness of 12mm has a fire endurance of 3 hours.
Q:What is the new fireproofing standard of external wall thermal insulation materials?
1, The height of fire barrier zone is not less than 300, and the thickness is same to the external insulation system; 2, the horizontal dividing joint should be set on the boundary between fire barrier zone and thermal insulation system; 3, Fire barrier zone is usually set in the horizontal direction, the fire barrier zone should be set above the door and window openings, the distance between the low edge of barrier zone and upward side of the hole should not exceed 500mm; 4, The construction of fire barrier zone insulating layer should carried on from bottom to top with EIFS insulating layer, which is not first leave the place in the EIFS insulating layer, and then paste fire barrier zone insulation board; 5, pasting the insulation board fire barrier zone insulation board and EIFS insulation board should be stitched closely, the width is more than 2mm gap application EIFS insulation materials or fire-retardant foam polyurethane padding;
Q:What the fireproofing materialare of the refractory kettle and where they can be sold?
Many places sell these. Nearly 10 years, can't brun when it is dry, adsorption. You can also baidu these materials. Heat transfer evenly, feldspar, clay and other raw materials with a ceramic products. Traditional casserole can not resist heat difference and also can withstand for 100 high temperature without crack. Aiming at the problem of traditional casserole, easy to crack and air permeability, people joined the spodumene on raw material, produce a high-temperature resistance casserole. It is produced after the high temperature burning makes an earthenware pot to keep the original advantages. Hebei has many places to sell these materials and is also relatively cheaper. The traditional casserole has features of not easy to transfer heat's quartz and slow cooling. Due to production technology and raw materials, it greatly improves the casserole' practicability after research and improvement.
