Why use calcium gluconate solution when the skin stained with hydrofluoric acid? The skin stained with hydrofluoric acid, running water must be wash the wound surface residues, it can help distribute heat at the same time, and reduce the secondary damage. Hydrofluoric acid penetration ability of the organization is strong, the flushing effect is often unsatisfactory and need to tie in with the soaking solution of calcium gluconate. Soaked in a solution of calcium ion and fluorine ion binding calcium fluoride formation and lose the corrosion effect of skin tissue, and application of sodium bicarbonate of hydrofluoric acid neutralization, glucocorticoid can inhibit the activity of proteolytic enzymes and coenzymes, and has anti tissue amine, so as to reduce the hydrofluoric acid destruction.

Hydrofluoric acid has been widely used in stimulation treatments since 1935, when mud acid was introduced to the petroleum industry. Originally, this hydrochloric-hydrofluoric acid mixture was intended to remove mud filter cake, but it has since been successfully applied to many other oilfield problems. Mud acid treatments have been unusually successful in sandstone reservoirs where hydrochloric acid is unreactive due to a lack of enough calcite in the formation. The relatively small amount of hydrofluoric acid present (2.1 per cent) reacts with sand grains, clays and traces of calcite which are generally present in sandstone reservoirs. Since hydrofluoric acid (HF) is the key to mud acid success, this research effort has been dedicated to gaining a more thorough understanding of the basic chemical and physical principles involved as hydrofluoric acid reacts. Hydrofluoric acid's reactivity with silica makes it unique in application. Other mineral acids such as hydrochloric, sulfuric or nitric are unreactive with most silicious materials which comprise sandstone formations. A typical sandstone reservoir may contain 50 to 85 per cent silicon dioxide, more commonly called sand or quartz. Hydrofluoric acid reacts as follows:

Hydrofluoric acid stained nail, can we ingore ? Because there is no nails keratosis layer and the infiltration of the role of the hydrofluoric acid will be stronger. Therefore it is necessary to timely treatment, lest cause matrix of bone injury.

Hydrofluoric acid splashed into the eyes inside,what shall we do? Filed eyelid, rinse immediately with plenty of water, and then glucose acid calcium, cortisone eye drops, erythromycin, bFGF and eye drops eye.
