鉴于制剂室工作的需要.要求洗并及灌酸间墙壁或地面须用耐酸瓷砖铺贴,用耐酸胶泥作粘合剂,而耐酸胶泥处方中含耐酸水泥,其中含有氟硅酸钠,笔者认为该化工原料较多溶于热水,可溶于盐酸中,其中毒症状同氟化物,成人致死量为2～4g.有剧毒不能用于食品工业故认为采用耐酸水泥及耐酸胶泥不妥。我们认为选择无毒的树脂胶泥,或其它多种新型无毒的胶泥粘合剂为好。特提示供兄弟单位参考。
In view of the needs of the work of the preparation room, it is required that the walls and floors of the washing and filling room should be coated with acid-resistant tiles, and the acid-proof cement be used as the adhesive, and the acid-proof mortar prescription contains acid-resistant cement containing sodium fluorosilicate, which I believe The chemical raw materials are more soluble in hot water, soluble in hydrochloric acid, in which the toxic symptoms with fluoride, adult lethal dose of 2 ~ 4g. Poisonous can not be used in the food industry, so that the use of acid-resistant cement and acid clay is not appropriate. We believe that it is better to choose non-toxic resin cement or other new non-toxic cement adhesives. Special hints for brothers’ reference.
