Product Description
hydrofluoric acid is an aqueous solution of hydrogen fluoride and is a colorless transparent liquid. The density was 1.15g/mL(so%HF) at 25 °c. It is highly corrosive to metals, glass, concrete, etc.
Use
hydrofluoric acid can be used as a cleaning agent for stainless steel to remove oxides from metal surfaces and increase the corrosion resistance of stainless steel. Hydrofluoric acid is a weak inorganic acid, less corrosive to metals than sulfuric acid and hydrochloric acid. Hydrochloric acid at room temperature in addition to silicon scale, iron scale ability, can clean austenitic stainless steel, will not produce stress corrosion, cleaning time is short, high cleaning efficiency, good surface condition. But hydrofluoric acid on cast iron, titanium and other metal corrosion. It can be mixed with hydrochloric acid and nitric acid, and the content of hydrofluoric acid used alone is generally 1.0% to 2.0%.
Safety
It is highly corrosive and can corrode glass and nails. Inhalation of vapors should be avoided. Hydrofluoric acid is corrosive to the eyes, skin and mucous membranes, and inhalation can cause pulmonary edema. Skin contact caused by redness and burning sensation, eyes will appear blurred vision, Laryngalgia, Cough, Dyspnea after inhalation. After entering the digestive tract will cause Abdominal Pain, Diarrhea, Vomit. Ingestion of fluid can lead to esophageal and gastric necrosis, circulatory collapse, and even death. Personnel exposed to hydrofluoric acid should be protected. When the skin is exposed to hydrofluoric acid, it should be immediately washed with a large amount of water, and in severe cases, it should be sent to the hospital for treatment. Attention should be paid to ventilation at the work site. Should be stored in a ventilated warehouse. Containers must be sealed and protected from direct sunlight. When metal can release hydrogen, Mars easily cause combustion or explosion, and therefore can not be mixed with metal powder, oxidant, alkali, organic matter and other storage.
