By signing the Paris agreement, Europe has embarked on an environmental revolution.
Taking into account the trend of modern production towards the exclusion of hazardous raw materials and environmentally unfriendly technological operations, our company, within the framework of its production and its capabilities, is developing a whole range of products that help to reduce the application of environmentally unsafe refractory and thermal insulation materials.
First, this concerns the phasing out the use of products made of ceramic fibers of aluminosilicate composition and the transition entirely to bio soluble fiber.
Our company successfully employs the technology of applying a thermally expanding coating with an identical chemical and phase composition to the working surface of a lining made of bio soluble fibers. This coating increases the operating temperature of the protected lining by 250 – 400 degrees, while maintaining its thermal insulation properties.
This application eliminates the main disadvantage of bio soluble high-temperature fibers, which implies their insufficiently high application temperature, often not exceeding 1000°C. The bio-soluble thermal insulation is technically justified up to this temperature, but at higher temperatures, the fibers are destroyed and, accordingly, the entire lining of thermal units is destroyed. This process is especially intense in the presence of vibration, even with a minimum amplitude and low power.
Even theoretically, this type of fiber, if it retains its bio-soluble properties, cannot have a long-term operating temperature of more than 1100°C. This indicator, at the present time, is precisely what is holding back the promotion of this product in the high-temperature thermal insulation market.
The thermal expansion coating has the same chemical and phase composition
Thus, in the case of a complete ban on aluminosilicate fibers application, the question of reducing the energy efficiency of heat-insulating materials based on bio soluble fibers will arise.
This problem is successfully solved with the use of our developed coating, which not only increases the operating temperature of the bio soluble fiber, but also strengthens the surface layer of the lining.
