SGS certificate factory price black / green silicon carbide made in china

Q: What problems should be paid attention to while using refractory materials under a controlled atmosphere?: Pay attention to the performance of the materials, and the use of non oxide materials!

Q: What refractories are accessible with ease in daily life? This material is suitable as a disposable mold and crucible for melting brass.: The refractory that you want is high temperature furnace which you can buy from the market.

Q: Who knows about the differences between 3M fireproofing materials and ShiLiDe materials?: ShiLiDe materials are rubbish which can not used in many industries now, because the main materials of which are mineral wool boards. These boards are harmful to human body, will lead to chronic poisoning, and the quality of which is bad! You must pay attention to it! They can not be used in chemical and pharmaceutical plants.

Q: Is aluminium oxide refractory material?: Calcination aluminium oxide is refractory material of fine performance made from pure aluminium oxide through high-temperature calcination. It can be made into coarse-grained material, fine-grained material, fine powder and micro powder, which can be made into pure jade burnt products. For example, corundum brick, lightweight corundum bricks. It can also be made into a variety of unburning products together with other materials, such as carbonaceous materials. For example, aluminum carbon and aluminium zirconium carbonaceous materials. As for the production of unshaped refractory material, there are more species. It can be corundum, rubing grain, corundum spinel and can also be added into other materials to improve specific performance. It isn't limited to high-alumina castable refractory and it can be castable refractory, ramming?mass, impressionable plastic material, gunning mix and refractory mortar.

Q: What are refractory materials?: Refractories can be divided to two categories based on the shape and three categories according to the chemical nature of acidity, neutralily and alkalinity. Alkaline refractory materials are magnesia-carbon brick, magnesia chrome brick, calcium magnesium brick and magnesia-chrome bricks. Neutural refractory mateial are high alumina brick, corundum brick and clay brick. Case-hardened refractory materials are castable, ramming mass, gunning mix, coated mix, dry vibration material, etc.

Q: How many fire endurance grades are the AAA fire resisting shutter divided?: The different fire resistant levels of the building have different requirements of the fire endurance of the building component. According to the fire endurance, the fire doors can be divided into Class A, Class B and Class C fire doors with the fire resistances are not less than 1.20h, 0.90h and 0.60h. Even the fire resistant level of B can also use the first rate fire resistant door.

Q: Can polystyrene foam color steel plate be used as decorative fireproofing material ?: As far as I am concerned, polystyrene foam color steel plate cannot be used as decorative fireproofing material. Because polystyrene flame retardant and non-flame retardant of the points, from the fire retardant is generally self-extinguishing. Polystyrene is the polymer synthesized by styrene?monomer through free radicals polycondensation reaction. It is a transparent thermoplastic?plastic. With above 100 ℃ glass transfering temperature,it is often used to make a variety of disposable container and disposable foam lunch box which have to withstand the boiling water temperature.

Q: Where do China and foreign countries do more refractory materials?: The domestic production of refractory materials base in Henan Xinmi, Xinmi has a lot of production of refractory material factory, Zhengzhou gold refractories plant is relatively large, there is a need to go to visit the factory.

Q: Can anyone tell me what is a high alumina refractory?: Refractories refer to a class of inorganic non-metallic materials whose refractoriness are no less than 1580 ℃. Refractoriness is the Celsius temperature when cone-shaped samples can resist high temperature without softening and melting down in the absence of a load. But it is not accurate to define refractory merely by judging that whether the refractoriness is no less than 1580 ℃. Currently, the materials whose physical and chemical properties allow them to be used in high temperature environments are called refractories. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, power and so on, among which the metallurgical industry is the largest demander in this regard, accounting for 50% to 60% of total output. Hope it will help you out!
