New technology of the hottest ceramic fiber
2022-08-11- Detail
The University of Warwick announced in May 2003 that the UK has successfully developed a new process for the production of ceramic fibers. The new process can not only improve the performance of ceramic fibers by increasing the production capacity to 100000 tons in about two years, but also effectively avoid the production of too fine fibers harmful to health in the processing process
ceramic fiber has both strong hardness and certain elasticity, And there's a good one "C919 is the first time to adopt the thermal performance of aluminum lithium alloy on a large scale. Therefore, in recent years, it has been widely used to manufacture high-temperature furnace walls and light components for automobiles or aircraft. However, some studies have also found that some too fine fibers produced in the manufacturing process of ceramic fibers are likely to cause harm to human health. Some European countries have listed ceramic fibers with a diameter of less than 1 micron as carcinogens. Medicine also believes that if ceramic fibers If the diameter of dimension is less than 3 microns, it is easy to be absorbed and can be made of round steel bars; It is potentially harmful to important substances entering human lungs
therefore, it is called 'universal material'. Through research, the processing technology group of the University of Warwick in the UK found that using a sol-gel blowing technology can effectively control the fineness of the produced ceramic fibers, so as to completely eliminate the generation of too fine fibers in the manufacturing process. Researchers have successfully produced ceramic fibers with a diameter of no less than 3 microns and uniform fineness after experiments with this technology
researchers also found that if the formation process of spinning sol is accurately controlled in sol gel blowing processing, the ceramic fiber produced will not only have magnetism, piezoelectricity and conductivity, but also its high-temperature fire resistance can reach the level of ordinary ceramics
