FAQ
Q1: How do you control the products quality?
A1: With strict quality control system throughout the materials selection and production process, our refractory and ceramic fiber products quality is effectively controlled to meet customer requirements.
From the raw materials selecting, our quality control begin. The quality certificates of raw materials are required and each batch will be tested before using. During production, the quality control are conducted by workers and then each piece will be sorted and examined by quality supervis
Q2: What`s the lead time for my order?
A2: It depends on customers’ requirements and our production schedule. And usually we need 30-60 days for refractory bricks,10-25 days for unshaped refractory materials and 10-20 days for ceramic fiber blankets
- Q: Application of electric high temperature regulating valve?
- Many kinds of refractory materials, usually by refractoriness level is divided into ordinary refractory materials (1580 to 1770 DEG C), advanced refractories (1770 to 2000 DEG C) and special refractories (more than 2000 DEG C); according to the chemical characteristics into acid refractory material, refractory materials and basic refractory materials. In addition, there are refractories for special occasions.
- Q: How much is a thermal brick?
- Insulation brick prices also have a great relationship with the material and workmanship, such as clay brick price is much lower than high alumina brick, mullite and corundum brick prices will be higher.
- Q: Zirconium corundum 25 content and 40 content, how to distinguish in appearance?
- Fused zirconia corundum brick is pure alumina and zirconia containing silica 65%, about 34% of the zircon sand in electric furnace melting after internalization into moulds cooling and the formation of the white solid, the petrographic structure by zirconium corundum and plagioclase eutectoid and glass phases, from the phase is eutectoid zirconium corundum and plagioclase phase, glass phase filling between their crystallization.
- Q: What is the price of concrete self insulation bricks?
- If you really want to buy thermal insulation brick, do not simply look at the price, but also to consider the quality of the product. (a piece of brick in the market basically in 6 yuan, if there is a floating price if it is because of the size of the insulation brick or distance, but floating slightly.)
- Q: Which is good, glazed brick and whole cast glazed brick?
- Vitreous tile is all ceramic tile, the material is hard, strong wear resistance, smooth finish is very good, in general, looks very bright. Microcrystalline brick, corundum brick Market said, they really mean bohuazhuan. Because of its low water absorption and high strength and hardness, glazed tile has been widely used. Many hotels, shopping malls and office space are widely used glass tile.
- Q: Which is faster for heat transfer between corundum bricks and high alumina bricks?
- For example: 75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.
- Q: What is the difference between corundum and high alumina?
- The main component of high purity 99 corundum brick is corundum sand,90 corundum brick is mainly composed of corundum sand and a small amount of Suzhou soil, mullite.
- Q: High temperature refractory material?
- Now the definition of refractory materials, has not only depends on whether the refractoriness at 1580 DEG. Refers to the current refractories used in metallurgy, petrochemical, cement, ceramics and other production equipment with inorganic non-metallic materials.
- Q: Is liquid phosphoric acid two aluminum hydrogen flammable?
- Liquid phosphoric acid two hydrogen aluminum features: easy mixing, molding, especially suitable for field construction, so liquid phosphoric acid two hydrogen aluminum is not flammable
- Q: How do corundum bricks bind?
- Each refractory brick is provided with corresponding refractory mud, and corundum bricks are bonded with corundum mud.
