產(chǎn)品簡介 產(chǎn)品性能： 氟化氫ＨＦ，常成二分子狀態(tài)H2F2存在。 和水的親合性：液態(tài)氟化氫具有很強的脫水能力，木才、纖維一旦與其接觸立即碳化。這些產(chǎn)品均可用于致冷劑、氣霧劑，工業(yè)上還用作金屬機件的清洗劑和聚氨酯、聚乙烯等泡沫塑料的發(fā)泡劑。平均每噸不銹鋼消耗10kg氫氟酸（以100％HF計），氫氟酸還用于玻璃蝕刻、金屬拋光、稀有金屬鈮和鉭的分離，濕法磷酸化除鉻、鋁等。盡管浙江衢州化工廠90 年代初由德國引進10000噸/年氫氟酸生產(chǎn)線，使之成為中國的氟化工基地，但仍適應(yīng)和滿足不了國內(nèi)的需求，制約和束縛了某些關(guān)聯(lián)行業(yè)的發(fā)展，在國際上仍處于較為落后的狀況。４、生產(chǎn)工藝、技術(shù)及流程 生產(chǎn)方法： 氟化鈣(螢石)與濃硫酸反應(yīng)，可制得氟化氫并副產(chǎn)硫酸鈣。℃，以進一步除去殘存的少量硫酸和水，％或更高純度的無水氟化氫。 排水：企業(yè)排水已有排水專管，通過沉淀，中和理達國際標準后集中排水，不會對周圍環(huán)境造
