HCl acid is widely used in many industries: Food industry, tanning, textile industry, mechanics, metallurgy, electroplating, total Hopes of organic compounds ...
+ Rusty: Use HCl acid solution to clean the surface Iron before going through the next stage such as rolling, pressing, galvanized, painted ...;
+ Producing inorganic compounds: producing water treatment chemicals PAC; Producing calcium chloride, nickel (II) chloride is used for electroplating and zinc Chloride for plating industry and electrochemical battery production;
+ Producing organic compounds: PVC synthesis, bisphenol A export polycarbonate, activated carbon, Ascobic acid, as well as in some products of the pharmaceutical industry;
+ Oil exploitation: HCl acid can be used to pump inside The stone layer of the oil well is to dissolve a part of the stone (also known as washing well) and created larger pores;
+ Control and neutralization: In industry requiring degrees Pure (food, pharmaceutical, drinking water), HCl acid is used to adjust pH of water to be treated. Also use HCl acid to neutralize wastewater industry, pool water ...;
+ Regeneration of ion exchange resin: use HCl acid with content Fe3+ ≤ 0.8ppm to separate the cations adsorbing plastic particles: Na+ replaced by h+, Ca2+ replaced So 2 o'clock+ (If the iron content in large acids will lose activity calculation of plastic beads);
+ HCl acid used in food processing industry: hydrolysis Protein in meat, fish, plants to produce amino acids (amino acids makes protein of fish sauce);
+ Application in textile industry: HCl acid used in overtime The fabric dyeing process (iron content requires less than 0.03%acid);
+ Some other applications: tanning, house hygiene, production Gelatin, food additives.
+ Respiratory: toxic HCl gas for respiratory system, strong corrosion should When inhaled, there is a burning sensation, shock, breathing, sore throat. Maximum concentration Allow in the air: 0.25 ÷ 10 mg/m3 air.
Handling measures: Bring the victim to the air with clear air Heaven, artificial respiration if the victim stops breathing. Provide oxygen when the victim breaths hard Towels (medical staff perform).
+ Eye: HCl acid corroses the mucosa, causes pain, no See clearly, serious burns.
Handling measures: Need to wash eyes with clean water right after the next Contact for about 15 minutes then go to the medical facility for treatment.
+ Skin: HCl acid causes skin burns, itching, burning.
Processing measures: Remove immediately clothes and protective clothes when sticky solution, wash skin with lots of clean water.
+ Digestive system: When taking HCl acid, it is shocking, may be unconscious.
Processing measures: Do not cause vomiting unless there is instructions Medical staff, need to be transferred to the medical facility immediately.
Contains:
+ Packaging in a bottle, closed packaging.
+ Avoid near metal, alkaline solutions.
+ Suitable materials as containers, equipment, pipes HCl acid: Composite, glass, PVC, PE, PP, PA ...
+ Materials are not used containing HCl acid: Most needles Type and alloy.
Preserve:
+ Do not mix with strong bases, metals and alloys, substances reducing and burning substances, powerful oxidants.
+ Leave in a cool place, good ventilation, warehouse background covered with coating Composite or Black corrosion.
Transport:
+ Use compatible materials to make fortune containers Transfer HCl acid.
