- Q: What is the common inorganic fireproof and thermal inuslation matertial?
- inorganic materials of insulation materials 1, inorganic thermal insulation materials are mainly concentrated in the materials that have a certain insulation effect and can achieve level A fireproofing, such as aerogel blanket, glass wool, rock wool, expanded perlite and micro-nano thermal baffle. 2, rock wool production is harmful to human body, workers also do not want to occure the situation under the construction. The cycle of rock wool construction plate is long about 2 years from construction to production. The supply of the domestic wool market also cannot meet the requirements for use. 3, expanded perlite has great weight and high water absorption. 4, the insulation performance of micro-nano insulation panels is 3-5 times that of conventional insulation materials, commonly used in high temperature environment, but is more expensive. 5, aerogel blanket is level A1 inorganic fireproofing building materials, thermal conductivity at room temperature is 0.018W / (K · m), and absolutely waterproofing, its insulation performance is 3-8 times of traditional materials, which can replace the unenvironment-friendly froconventional flexible material with poor insulation properties, such as glass fiber products, asbestos insulation felt and silicate products.
- Q: What do RH and DH stand for in refractories?

- Q: Application of refractory materials in petroleum industry
- Our natural gas transportation, chemicals, equipment, packing, safety, insulation, and even building materials are available.
- Q: What is the difference in the nature between the refractory material and thermal?insulation?material
- thermal?insulation?material is used to thermal insulation and the transfer of heat insulation. refractory material is defined as greater than 1580 ° non-metallic materials, such as calcium silicate board. its using temperature can reach to 1100 degrees, and some can also be used at high temperatures, and all high-temperature industrial can't be oprated without it, and the using temperature of polycrystalline alumina fibers can reach to 1800 degrees
- Q: Development trend of refractories
- The foundation of China's refractories industry is still relatively weak, the utilization level of refractory material resources is low, the quality of refractory materials is not high, excess production capacity of ordinary products, the key products of some high-quality high technology content can be produced, but the quality is not stable, and the service life of refractory material consumption compared with foreign advanced level, there is a considerable gap. Therefore, the new trend of tracking foreign refractories science and technology development, carry out and supporting the development and application of advanced and basic theory research, to promote technological innovation of refractory materials, optimizing product structure, industrial structure adjustment, implementation of the strategy of sustainable development, it is very necessary.
- Q: How much is the content of boron carbide in refractory material?
- Is it available to iron materials?. Answer: It can be applied to all products, what you need is just a general proportion. Nevertheless, you’d better tell me what product it is exactly.
- Q: How many hours of the fire endurance time of the rock wool laminboard?
- Limit is usually two hours. Pay attention to it please.
- Q: Please answer the questions about the packing and transportation requirements of refractory materials.. Requirements for packing of refractory bricks
- Exports should be fumigated outside of South East asia. Pallet packing is the most common, convenient and inexpensive.
- Q: Graphite and other carbon materials may be oxidized to CO or CO2 at high temperatures. But why can they be refractories?
- There is no contradiction for this. Any substance can be combustible, but different materials have different ignition points.There are many types of graphite. Pyrolytic graphite has a much lower ignition point. Therefore, as long as it reaches at a certain temperature, it can convert into graphite. Mostly, in practical applications (such as brake pads will add a certain amount of graphite), graphite is required to have refractoriness of below 1000 ℃. Graphite can serves as both the combustible and refractory material. So, it can be used as a fire-resistant and high-temperature-resisrant material because graphite (lamellar graphite) has a ignition point of at least 3000 degrees in an oxygen free condition. The above information is for reference only and is offered by Xin Ruida Graphite Company.
