Q:How to measure the influence of high-temperature performance of the products refractory in the formation of the liquid phase.

Generally how can do high-temperature performance to measure how much liquid may affect hot bending strength rul refractoriness levels of high temperature creep?

Q:How to detect the acid resistance of refractory? Is there any standard? Thank you

There is a standard. However, the range what you said is a little big, it's difficult for me to say. But though the scope is a bit big, it should be: You can check the industry standard network, to see whether you can check it.

Q:how to use boiler fireclay

Boiler refractory, diluted with water to touch the places where needed, can be used after high temperature baking.

Q:Why can aluminium hydroxide not be used to make refractory material?

Hope my answer is helpful to you. It decomposes and produces aluminium oxide and water after heating, chemical equation for the reaction is: 2Al(OH)3=△=Al2O3+3H2O. Aluminium hydroxide can't be directly used to make refractory material because aluminium hydroxide is not stable.

Q:What is the main material of fireproof wooden door?

Fireproof wooden door refers to the door whose fire endurance of door frames, skeleton of the door leaf, door panels made of timber or timber work reaches the provisions of "GB50045-95 design of tall buildings for fire protection". Fireproof wooden door contain retardant timner, fireproof expanded perlite and fireproof?panel. Accessories: fireproof glue, fireproof hardware.

Q:What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?

I am not quite clear. But you should take two aspects into consideration, namely, no pollution and strong durability.

Q:Do you know the refractories?

Acidic material products: these products to quartz (SiO2) as the first phase, SiO2 is an acid oxide, helped named. Brick is representative of the product acid material; semisilica brick, alkali proof brick, acid brick in SiO2 content of 60% to 80%, is a semi acidic material.

Q:What's the difference of fire-resistant material's density, specific gravity and bulk specific gravity?

It usually used to test lightweight refractory. Density can be divided into apparent density (usually called as density) and true density: apparent density includes blow hole inside the sample; Unit weight is using quality to divide volume of sample and specific weight is used to represent liquid.

Q:I wanna ask that magnesium oxide is refractory?

Magnesium oxide is used in refractory material, because it has the following characteristics and properties: 1, high stability: Anti-oxidation, anti-reduction, thermal decomposition; 2, high melting point, 2800 degrees; 3, low prices. In particular, the stability and melting point is very good, I hope I can give you help.

Q:What kind of materials are needed to make refractory bricks?

According to requirements, there are different materials, acid refractory material, such as silica bricks; neutral refractory material, such as high alumina brick; and basic refractory material such as magnesia brick.
