Cov tshuaj surfactants uas tsis yog ionic:
Lub lim tiam dhau los, kev lag luam surfactant nonionic tau poob qis. Ntawm sab nqi, cov khoom siv raw ethylene oxide tus nqi ruaj khov ib ntus, tab sis cov nqi cawv rog tau poob qis heev, rub kev lag luam surfactant nonionic thiab ua rau tus nqi poob qis. Ntawm sab kev muab khoom, ib lub Hoobkas hauv South China tau kaw rau kev kho thaum lub lim tiam, txo cov khoom lag luam. Txawm li cas los xij, qhov kev thov qis qis tau them rov qab rau qhov cuam tshuam ntawm kev muab khoom tsawg. Kev ua lag luam tau tswj hwm qhov sib npaug ntawm kev muab khoom thiab kev thov, tsis muaj kev muab khoom ntau dhau lossis tsis txaus, txawm hais tias qhov no tsis tau muab kev txhawb nqa zoo rau tus nqi. Ntawm sab kev thov, kev xav ceev faj tau kov yeej thaum cov tuam txhab downstream, xav tias tus nqi yuav poob qis ntxiv rau cov khoom siv raw, qhov tseem ceeb yog txo cov khoom muag uas twb muaj lawm. Kev thov kawg tseem qeeb, ua rau kev siv khoom muag qeeb. Kev yuav khoom tsuas yog txwv rau cov kev xav tau tam sim ntawd, tsis muaj kev txaus siab txaus los txhawb kev thov tseem ceeb.
Cov Tshuaj Anionic Surfactants (AES):
Lub lim tiam dhau los, cov nqi lag luam AES tseem poob qis, nrog rau qee cov neeg tsim khoom anionic surfactant txo cov nqi. Hais txog tus nqi, cov nqi ethylene oxide ruaj khov, tab sis qhov poob qis ntawm cov nqi cawv rog ua rau cov nqi txhawb nqa tsis muaj zog, ua rau muaj kev nyuaj siab ntxiv rau kev lag luam anionic surfactant. Kev muab khoom tseem muaj ntau, tab sis kev muag khoom tsis zoo. Txawm hais tias tus nqi poob qis rau AES, qhov poob qis tam sim no tsis tau txhawb nqa kev thov los ntawm cov neeg yuav khoom hauv qab. Feem ntau cov neeg koom nrog kev ua lag luam xav kom muaj kev kho tus nqi ntxiv, ua rau kev yuav khoom ceev faj tsom mus rau cov kev xav tau tam sim ntawd.
