Q:How to repair the boiler?: use refractory bricks and plastic refractory

Q:air-cooled razheng times of magnesia-alumina spinel refractory bricks: The ingredients are magnesium, oxygen, and aluminum. the components of spinel refractory can be magnesia-alumina spinel with excessive aluminium oxide, or magnesia-alumina spinel with excessive magnesium oxide. excessive magnesium oxide and aluminium oxide can form magnesia-alumina spinel in above 1700 degrees.

Q:Why is the house made of refractory bricks not warm in winter: Heating equipment can be used

Q:What is the use of refractory bricks: Refractory bricks are mostly used as furnace lining in high temperature industry. Such as the iron and steel industry blast furnace, hot blast furnace, converter; colored reverberatory furnace

Q:Is fireclay brick acidproof? Does clay brick anti corrosion when it's used to build chimney lining?: Refractory bricks anti acid and alkali after high-temperature calcination, and anti-corrosion won't be a problem

Q:What are the release agents of refractory bricks?: Alkalinity, the production process of alkaline, acid and alkali resistant transparent instant thickening powder, you can adjust the proportion according to the cost and needs of quality, environmental protection: One: Add the preservative into water to mix, after soaking one hour, then mixing evenly the production ratio, and then add the super core release agent into water to mix, add flavor pigment masterbatch into water to mix with water mixing, ensure completely dissolved, then add the waste oil, falvor is appropriate amount= release agent. Two, the newest recipe of release agent super core release agent masterbatch, waste engine oil, water, instant acidproof and alkaliproof transparent thickening powder, wire drawing powder, preservative, flavor and pigment= release agent super core wire drawing powder with water mixing, it is the most newly developed special core masterbatch and engine oil of Chengdu Hengfeng Hongye detergent factory, and it doesn't contain toxic solvents, especially 1, it has the following features, after thickening more than half an hour or so, mix evenly is ok, in a few seconds will waste oil and alkali: 10% of waste engine oil, 20% of release agent core masterbatch, 88% of water, 500g instant acidproof alkaliproof transparent thickening powder, 80g wire drawing powder, 1g pigment and preservative and lubricating oil and industrial grease, these integrate with water.

Q:How good is the hardness of corundum refractory brick?: The basic materials of corundum refractories are fused corundum or sintered corundum. the refractory brick containing more than 90% of Al2O3 is called corundum refractory brick. so, corundum refractory brick. Corundum has a high hardness (9 level of Mohs hardness) such as zirconium corundum refractory brick. Corundum refractory brick is resistant to acid well and melting point is also high, also known as pure alumina refractory brick products, , it has a good effect. These are closely related with the structure of the Al - 0 key, titanium corundum refractory brick, and other basic slag. It is used in high temperature oxidizing atmosphere or in reducing atmosphere. the metal and glass solution have good stability. a-Al2O3 is the main material of high temperature refractory brick and high temperature electrical insulating material .

Q:What material is good of refractory bricks?: It can also be divided into a variety of kinds, it mainly depends on where it is used, each has its own advantages, neutral three categories of refractory bricks have a variety of materials

Q:Clay brick, red brick, always fried brick how to do?: Clay brick and red brick are of very important quality and must not contain sand or gravel.

Q:What kind of coal should be used to burn refractory brick? and how many calories smoke is suitable?: Coal briquette's effect is also good
