Detergents production needs through mucous membranes and skin absorption can produce toxic effects on the body mainly on the enzyme systems have toxic effects, such as inhibition of succinate dehydrogenase can affect cellular respiration: fluoride and calcium in the bones or body fluids combined into difficult soluble calcium fluoride, calcium and phosphorus metabolism so, resulting in adverse effects on bone, causing bone sclerosis and osteoporosis, and to crown incomplete calcification Ferrer detergents production, enamel damage. Scope of dental erosion disease, bleeding gums, dry rhinitis, epistaxis, hyposmia and laryngitis, chronic bronchitis:: symptoms hydrofluoric acid as an important raw material of fluorine chemical industry can produce fluorine refrigerants, fluoropolymers polymers used for industrial cleaning rust stainless steel plant can not be used for medical devices, ferrous oxalate produced after descaling treatment oxalic acid is insoluble in water and rust reaction caused by the toxic effects of repeated oxalic acid poisoning mechanism can produce exposed parts irritant or corrosive acid can combine with calcium to calcium oxalate, which leads to another due to low blood calcium oxalate mainly excluded by the kidneys, it can be caused due to the deposition of calcium oxalate urolithiasis, renal calcium oxalate may be deposited in the liver, heart, lungs, blood vessels and other organs, and organ function abnormalities produce symptoms of poisoning: oral pain, ulcers (may have mucosal white phenomenon), dysphagia can not be used for medical devices rust, descaling treatment citrate when PH> 4 时citric acid descaling will generate ferric citrate effect caused by repeated precipitation Scope: At present mainly in the industry as the metal rust Rust is not recommended for use in medical devices, a hydrochloric acid descaling treatment, pre-wash to clean the boiler system and temporarily filled with tap water pipeline full, if the cleaning system contrast dirty water flow rate may be appropriate to progressive erosion. After scouring stick full level, and then firing the furnace hearth water heated to a predetermined temperature, the heating process always adhere to the water circulating in the cleaning system. 2, alkaline water constantly circulating in the process, a good number of the pre-accounting caustic agents participate in batches to the tank system's temporary. When caustic agent concentration and pH value reaches a predetermined index suspend dosing and continue to maintain the water cycle 6 ~ 8h were caustic. 3, after the completion of the caustic lye washed clean emissions, and then water washed, of course. Boiler cleaning agents and cleaning agents conventional solar water heater is not the same. 4, pickling suspended after reaching a predetermined temperature heating, clean water within the system continued to insist on continuous loop. And then participate in a corrosion inhibitor should participate and make sure that all of the cleaning system to adhere to meet concentration. And then participate in concentrated acid, acid speed should be slow. Especially carbonate scale is based boiler will add a lot of carbon dioxide gasification after escaping acid, acid speeds but can not be too fast. 5, after washing pickling is completed, the pickling solution with the fastest speed emissions, and do everything possible to clean high flow rates of water erosion Ferrer detergents wholesale system, in the shortest possible time for the water to reach a pH of 4 to 5. 6, Hou Furui passivated finish washing detergents to clean the entire boiler system washed over the water, and then the same way with the aforementioned boiler water temperature, while the amount of time to participate in accordance with the accounting formula deactivator and adhere to cycle, heating After heating to estimate the temperature of the suspension, and sampling analysis passivation solution of alkali concentration Ferrer detergents agent, Dongguan Ferrer trade (certified), Ferrer Ferrer detergents provided by the Dongguan City Trading Co., Ltd ..
