重鉻酸鈉在工业上应用很广,如金属加工、化学制药、油漆涂料、紡織和生产电鍍物品等。它是一种橙紅色結晶,溶于水,对于粘膜和皮肤有一定的刺激和腐蝕作用。凡从事上述工业和生产重鉻酸鈉的工人,与之經常接触或吸入就可以发生职业性疾病,甚至中毒,因此在我国迅速发展化学工业的今日,研究鉻化合物对人体的影响是必要的。本文报告某化工厂生产重鉻酸鈉車間工人90名所发生的皮肤和鼻粘膜病变以及其他病症的情况,結果和资料分析如下: 劳动卫生情况生产过程分为拌料、煅烧、浸出、制造、鉻酸、保全及其他7个工种。主要原料有鉻鈇矿(FeO、Cr_2O_3),石灰石,經过粉碎后与純碱拌合,在1100℃高溫反射炉內煅烧,轉化为水溶性六价鉻,用水浸取,加酸中和、压滤,滤出清液进行浓縮,再加硫酸进行
Sodium bichromate is widely used in industry, such as metal processing, chemical pharmacy, paint coating, textile and electroplate production. It is an orange-red crystal that dissolves in water and has some irritation and corrosion effects on mucous membranes and skin. Therefore, it is necessary to study the impact of chromium compounds on the human body in the rapid development of chemical industry in our country where workers engaged in the above industries and producing sodium birrate are exposed or exposed frequently to occupational diseases or even intoxicated. This paper reports on the production of sodium dichromate plant 90 workers in a chemical plant skin and nasal mucosal lesions and other conditions, the results and data analysis is as follows: labor and health conditions The production process is divided into spices, calcination, leaching, manufacturing, chromium Acid, preservation and other seven kinds of work. The main raw materials are chrome ore (FeO, Cr 2 O 3) and limestone, which are crushed, mixed with soda ash, calcined in a furnace with a high temperature of 1100 ° C., converted into water-soluble hexavalent chromium, leached with water, neutralized with acid, Filter, filter out the supernatant was concentrated, plus sulfuric acid
