Industrial cleaning agents commonly used surfactants: cationic surfactants / anionic surfactants / amphoteric surfactants / nonionic surfactants, general low-foam cleaners commonly used nonionic surfactants.
Industrial cleaning agents have gone through about the following development period:
1, chlorine solvents (hazardous to human health)
2, hydrocarbon-based solvents (need to be explosion-proof policy)
3, the use of surfactants in aqueous cleaning agents (high cost of treatment of cleaning waste)
4, strong alkaline electrolytic water equipment to produce strong alkaline Electrolyzed water (without adding any chemicals, no environmental pressure)
Chemical agents used for industrial dirt cleaning, generally should meet the following technical requirements. Cleaning agents for different cleaning purposes and cleaning objects, for these requirements can be focused or trade-offs.
(1) the speed of cleaning dirt, dissolve the scale thoroughly. Cleaning agent itself on the dirt has a strong reaction, dispersion or dissolution of the ability to remove, in a limited period of time, can be more thoroughly remove the dirt.
(2) the damage to the cleaning object should be within the limits of the production permit, the metal may cause corrosion has the appropriate measures to inhibit.
(3) cleaning agents used in cheap and easy to obtain, and based on localization; low cleaning costs, without excessive resource consumption.
(4) cleaning agent on the biological and environmental non-toxic or low-toxic, generated by the waste gas, waste liquid and waste residue, should be able to be processed to meet the requirements of relevant national regulations.
(5) Cleaning conditions are mild, and do not rely on additional strengthening conditions, such as temperature, pressure, mechanical energy, etc. do not need high requirements.
(6) cleaning process does not remain on the surface of the cleaning object insoluble material, does not produce new dirt rout, does not form a new harmful to the subsequent process of covering layer, does not affect the quality of the product.
(7) does not affect the cleaning process and site hygiene foam and odor.
(8) cleaning agent can not be flammable, explosive substances, or the need to clean the product or equipment has some potential safety threat.
(9) The cleaning agent is required to be as phosphorus-free and environmentally friendly as possible, and to reduce the COD value.
