Amphoteric surfactants in industrialdetergents
Water-based cleaning agent
Metal cleaning agent development trend isthe transition from solvent-based to water-based, water-based and thefrequently used amphoteric surfactants. Other types of high-pressure industrialdetergents such as detergents, sewage transport membrane scavengers, foamcleaning agent amphoteric surfactants can be used.
Amphoteric surfactants to ensure thecompatibility of the liquid product aspects of the components have a specialrole under alkaline conditions.
Currently most metal manufacturing metalcleaning operations using water-based formulations, which usually containalkali can remove the metal surface of the oil. Such as sodium hydroxide,sodium silicate, sodium orthophosphate, etc., a surfactant detergents help toimprove speed. Since the amphoteric surfactants stable in strong alkaline, andhas a high alkali-soluble, so the alkaline water-based cleaning agent that canbe used amphoteric surfactants. When the amphoteric surfactant moleculecontains a plurality of anionic groups, it is more conducive to the applicationof a strong base. Amphoteric surfactants in this case has a stronglyhydrophilic repulsion. It can exhibit hydrotropic functionality to meet theneeds in this regard the recipe, but also help improve the grain of dirt andrepulsion matrix. Furthermore, additional anionic group can increase thesolubility in alkali can make decontamination synergism.
Lubricating / cleaning automatic packagingline plays a very important role in the conveyor belt. In particular, is widelyused in beverage, milk, food processing industry, in this particularformulation will often amphoteric surfactants and soap compound used together.
Acidic cleaners
It has been suggested to use amphotericsulfonates, betaines and sulfobetaine amphoteric surfactant containing aceticacid, citric acid, hydrochloric acid, sulfamic acid, phosphoric acid, formicacid and other acidic cleaning agent. In the acid content of 2% to 5%, theamount of amphoteric surfactant is 5%. In many acidic formulations are requiredto change the rheology thickening agent formulation.
