Product Description:

General Information:

CMAX brand Silica bricks are made from high quality quartz tail sand, lime and mineralizing agent through the process of crashing, screening, mixing, pressing, drying and sintering.

 

Features of Refractory silica bricks for Glass Kiln:

1. high volume density of 2.34 g/cm3

2. high SiO2 content of 96%

3. low iron content of 0.8%

4. low melting point of 5%

 

Applications of Refractory silica bricks for Glass Kiln:

Because of the high temperature resistant performance significantly, long service life characteristics (as long as more than eight years) of refractory silica brick for Glass Kiln, it can significantly improve the quality of glass, so the refractory silica bricks are widely used in all kinds of glass furnace melting department, regenerator and other important parts.

Q:Who knows what kind of material the fire-proof plate use, and is it good?
It is the decorative board made by adopting silicious material or calcareous material as the main raw material, and blending them with certain proportion of fibrous material, lightweight aggregate, adhesive and chemical additive before steam pressing. It is a kind of new material and more and more frequently used currently not only for it is fireproof. Construction of the fire-proof plate has higher requirements on the adhesive, and the price of the fire-proof plate with better quality is more expensive than that of the decoration panel. The thickness of the fire-proof plate is generally 0.8mm, 1mm, and 1.2mm. So it is the best material for making cupboards.
Q:What kinds of refractory materials that can resist 3,000 Celsius degree?
steel fiber reinforced spalling resistant bricks, phosphate bonded high alumina brick with high strength and wear-resistance, and high R.U.L bricks and composite bricks
Q:Who can introduce the difference between galvanized fireproof coatings and steel structure fireproof materials?
When the steel surface derusted, it generally needs to brush rich-zinc primer before spraying fireproof coating. Fireproof coating plan itself includes anticorrosion plan, and fireproof coating is just a layer of coating plans, which is an intermediate layer in general. Fireproof coating plan generally includes primer, fireproof coating and finishing paint. Some fireproof coatings can be directly painted on the bare steel elements without primer and finishing paint. Galvanized surface generally is not necessarily needed for brushing fireproof coating. Fireproof and galvanized surface have relatively poor bond strength, so it is advisable to brush transitional lacquer or micaceous iron on the galvanized surface.
Q:The primary problem, does the gas permeable brick is fired refractory bricks(refractory) ?
gas permeable brick have two types:built-in type and external mounted type. the built-in gas permeable brick and the external mounted gas permeable brick are usually made by fire burning, and small part of bricks are made by the low temperature heat.
Q:Which one is the best refractory material?
1, Acid refractory usually refers to the refractory material whose content of SiO2 is more than 93% , and is characterized by erosion resistance to acid slag under high temperature , but it is easy to react with alkaline slag. Commonly used acid refractory materials include silica bricks and clay bricks. 2, Alkaline refractory material is a kind of refractory material whose components are magnesium Oxide or the mixture of magnesium oxide and calcium oxide. 3, Aluminosilicate refractory refractory material refers to refractory material which makes SiO2-Al2O3 as the main component. According to the content of Al2O3, it can be divided into semi silica (Al2O3 15~30%), clay (Al2O3 30~48%), high alumina (Al2O3 > 48%). 4, Fusion-cast refractory material refers to a kind of refractory product that melt the batch through some certain methods refractory products, and then pouring into a certain shape. 5, Neutral refractory materials mean that under high temperature, don’t react with acidic or alkaline slag. 6, Special refractory material is a new type of inorganic nonmetal material, which is developed on the basis of traditional ceramic and refractory materials. 7, The amorphous refractory material is a mixture of refractory aggregate and powder, binder or admixture, which can be used directly or after adding the appropriate liquid mixing.
Q:What are grade classifications of the external walls fireproofing material?
1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3 combustion performance is level B2 insulation material: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
Q:Fefractory of aluminium oxide.
Do you mean the alumina hollow ball brick? We can exchange private messages in specific.
Q:What is the fireproofing requirements of external wall thermal insulation materials?
According to the "building external wall insulation fire barrier zone technical regulations" to be published: it is not less than the level B2. But before the procedure was published, it should be strictly implemented the document, level A is the best, I hope to help you, hope to adopt
Q:What are the differences of ceramics and refractories? Is the ceramics belonging to refractories?
No In the high school chemistry, the former is talking about the traditional inorganic material, the latter is belonged to the new materials.
Q:How much refractory material is needed when 1 million ton coke oven is produced?
