The broad concept of penetrant refers to a class of chemicals that can help the substance that needs to be permeated to penetrate the substance that needs to be permeated, and the industry generally uses surfactants (which can be anionic or non-ionic) or organic or inorganic solvents. Penetrants are generally divided into two categories: non-ionic and anionic. The non-ionic ones are JFC, JFC-1, JFC-2, JFC-E, etc. The anions are rapid penetrant T, alkali-resistant penetrant OEP-70, alkali-resistant penetrant AEP, high temperature penetrant JFC-M and so on.
① Classified by application process.
Penetrant for pre-treatment (including: penetrant for desizing, boiling, bleaching, mercerizing, wool carbonizing, etc.), dyeing penetrant, printing penetrant, finishing penetrant, etc.
② Classification by application pH range.
Strong alkaline penetrant resistance, weak alkaline penetrant resistance, near neutral penetrant, weak acid penetrant resistance, strong acid penetrant resistance.
③ Classified by ionic type.
Non-ionic penetrants, anionic penetrants, compound penetrants, etc., rarely use amphoteric and cationic penetrants.
④ Classification by raw material variety.
Sulfated castor oil, Sodium alkyl sulfonate, Sodium alkyl benzene sulfonate, sodium alkyl sulfate, sodium para-alkyl sulfonate, Sodium alkyl sulfate, Sodium a monoalkyl sulfonate, Sodium alkyl naphthalene sulfonate, sodium succinate alkyl ester sulfonate, Yigapu T, sodium sulfamate, fatty alcohol polyoxyethylene ether, alkyl phenol polyoxyethylene ether, polyether, phosphate compounds, And alcohol compounds, ketones, ethers and so on.
