石墨是碳的结晶体,是一种非金属材料,具有耐高温,导电、导热、润滑、可塑和抗腐蚀等性能。由于它具有金属、非金属及塑料等所具有的优良特性,因此广泛应用于冶金,机械、化工、电气、原子能及国防等工业部门中,关于石墨粉尘本身对肺脏是否有致纤维化作用,至今意见还不一致。随着我国社会主义建设事业的飞速发展,石墨的生产和使用更加广泛,因而接触石墨粉尘作业的工人也逐渐增多,因此,研究石墨粉尘对机体的危害性质有着重要的实际意义,本实验的目的是了解土状石墨粉尘本身对肺脏是否有致纤维化作用。
Graphite is a crystalline carbon, a non-metallic material with high temperature, electrical conductivity, thermal conductivity, lubrication, plasticity and corrosion resistance. Due to its excellent properties of metal, non-metal and plastic, it is widely used in metallurgy, machinery, chemical, electrical, atomic energy and defense industries. So far, whether graphite dust itself causes fibrosis to the lungs has so far been observed Not the same. With the rapid development of socialist construction in our country, the production and use of graphite is more extensive, so that the workers exposed to graphite dust are gradually increasing. Therefore, it is of great practical significance to study the harmful properties of graphite dust to the body. The purpose of this experiment Is to understand the earth-like graphite dust itself on the lung fibrosis caused by the role.
