三、包装：
工业级氢氟酸：采用聚乙烯塑料桶：10kg/桶，25kg/桶，200kg/桶，1000kg/桶。
试剂级氢氟酸：采用聚乙烯塑料桶：7kg/桶，21kg/箱，1000kg/桶。（纸箱装为纸箱内位3桶7kg/桶的聚乙烯塑料桶）
四、重要说明
桶装氢氟酸的度数通常为30-70%，可根据客户的需要进行生产。
五、用途
由于氢氟酸溶解氧化物的能力，它在铝和铀的提纯中起着重要作用。氢氟酸也用来蚀刻玻璃，半导体工业使用它来除去硅表面的氧化物，在炼油厂中它可以用作异丁烷和丁烷的烷基化反应的催化剂，除去不锈钢表面的含氧杂质的“浸酸”过程中也会用到氢氟酸。氢氟酸也用于多种含氟有机物的合成，比如teflon(聚四氟乙烯）还有氟利昂一类的致冷剂。 hydrofluoric acid
one, the introduction of hydrofluoric acid, hydrofluoric acid to aqueous solution of hydrogen fluoride, colorless transparent, has a strong irritating smell and corrosiveness, can rapid corrosion silicon-based materials such as glass. mainly used for fluoride salt production and etched glass, metal cleaning and surface treatment, etc.

3, packing:
industrial-strength hydrofluoric acid: the polyethylene plastic bucket: 10 kg/barrel, 25 kg/barrels, 200 kg/barrels, 1000 kg/barrel.
reagent grade hydrofluoric acid: the polyethylene plastic bucket: 7 kg/barrels, 21 kg/box, 1000 kg/barrel. (in cartons as the cartons a polyethylene plastic bucket) 3 barrels of 7 kg/drum
fourth, important note
barrel hydrofluoric acid degree usually is 30-70%, according to the customer's need for production.
fifth, use
because the hydrofluoric acid to dissolve the oxide ability, it is in aluminum and uranium purification plays an important role. hydrofluoric acid is also used to etch glass, the semiconductor industry to use it to remove oxide on the surface of the silicon, it can be used for isobutane and butane in refinery alkylation reaction catalyst, removal of oxygen impurity on the surface of the stainless steel in the process of "acid" is also using hydrofluoric acid. hydrofluoric acid is also used in a variety of synthesis of fluorinated organic matter, such as teflon (ptfe) and refrigerant freon.
