Lijin County Changhua Chemical Machinery Factory of Dongying City, Shandong Province, according to the climate change conditions and equipment operation characteristics, starting from various aspects, a mandatory "physical examination" of all workshop production equipment in a planned manner. In the "medical examination" of the equipment, the plant strictly followed the contents and requirements of the "cross" operation and carried out comprehensive maintenance on the equipment to eliminate dirt, looseness, leakage, and lack of phenomena and ensure normal operation of the equipment. The workshops started from a small place, focused on details, and comprehensively improved the equipment in good condition, so that minor problems were promptly rectified by the workshop and the team, and major problems were promptly reported. The plant has also established and improved detailed equipment files and rewards and penalties systems, giving employees appropriate incentives for discovering hidden dangers to mobilize the enthusiasm of employees and adding a “safety symbol†to equipment operations. Silicon nitride (Si3N4)is an inorganic material technical ceramic that does not shrink during sintering. This advance ceramic has the properties of high strength, low density and high temperature resistance, especially hot-pressed silicon nitride is one of the hardest materials in the world. In addition, Si3N4 has low coefficient of thermal expansion and high thermal conductivity, so it offers excellent thermal shock resistance.

Due to the improvement of the purity of Si3N4 raw materials, the rapid development of Si3N4 powder molding technology and sintering technology, and the continuous expansion of application fields, Si3N4 is becoming an engineering structural ceramic, occupying an increasingly important position in the industry. Furthermore, Si3N4 ceramics have better mechanical properties, thermal properties and chemical stability than other high-temperature structural ceramics such as oxide ceramics and carbide ceramics. It is used as high-temperature structural parts in automobile engines, gas turbines and combustion chambers.
Currently, we produce variety silicon nitride ceramic nozzles in soldering appliance, silicon nitride ceramic rod,silicon nitride thermalcouple protective tube, silicon nitride ceramic heating parts in automation and gas equipment, electrical insulating ceramic parts in medical and so on.
