氢氟酸是氟化氢的水溶液,有很强的腐蚀性,主要用于制造药物、塑料、冷冻剂、灭火剂、杀虫剂、弹性剂、防酸物处理剂等,以及金属铸件砂型残粒的清除、陶器的雕刻、地质矿样的分析、半导体器件的清洗等等。在生产过程中由于不注意或意外事故常引起氢氟酸灼伤。低浓度氢氟酸接触皮肤后,人们往往没有什么感觉,也不太注意,但经过2～3小时后感到灼伤部位剧烈疼痛。如果是高浓度氢氟酸灼伤,可立即产生针刺样疼痛,常常难以忍受,甚至打止痛针,有的疼痛也不减
Hydrofluoric acid is an aqueous solution of hydrogen fluoride, a strong corrosive, mainly used in the manufacture of drugs, plastics, refrigerants, fire extinguishing agents, insecticides, elastomers, anti-acid treatment agent, and metal casting sand remnants Removal, carving of ceramics, analysis of geological samples, cleaning of semiconductor devices, and more. In the production process due to lack of attention or accidental cause hydrofluoric acid burns. Low concentrations of hydrofluoric acid after contact with the skin, people often do not have any feeling, nor too much attention, but after 2 to 3 hours after the site of intense pain felt burns. If it is a high concentration of hydrofluoric acid burns, can immediately produce acupuncture-like pain, often unbearable, and even hit the pain needle, and some pain is not diminished
