Cov ntxhua khaub ncaws ntxhua khaub ncaws yog cov tshuaj ntxuav cov kua nruab nrab uas feem ntau tsim los ntawm cov tsis yog -ionic surfactants; nws haum rau ob txhais tes - ntxhua khaub ncaws thiab tshuab - ntxhua khaub ncaws ntxhua khaub ncaws. Nrog tus nqi pH ze rau nruab nrab, nws yog tus cwj pwm los ntawm kev muaj zog solubility, yooj yim ntawm yaug, thiab sai biodegradability. Ua raws li QB / T 1224 tus qauv kev lag luam, nws ua rau tawv nqaij tsawg dua piv rau cov khaub ncaws ntxhua khaub ncaws. Nws cov khoom xyaw tseem ceeb suav nrog cov uas tsis yog- ionic surfactants, nrog rau cov khoom siv xws li cov neeg tsim khoom, cov thickeners, thiab cov enzymes- tom kawg uas muaj peev xwm ua rau cov protein ntau-raws li thiab roj- raws li stains.
Cov ntxhua khaub ncaws ntxhua khaub ncaws ua tiav kev ntxuav los ntawm kev siv cov surfactants kom txo qhov nro ntawm cov dej, yog li tso cai rau cov tshuaj nkag mus rau hauv cov khaub ncaws fibers thiab encapsulate stains. Thaum yuav khoom, cov neeg siv khoom yuav tsum nrhiav cov yam ntxwv xws li homogeneous tsos, ib qho tshuaj tsw qab ntshiab, thiab cov viscosity nruab nrab; Nws raug nquahu kom xaiv cov khoom lag luam nrog cov ntsiab lus tseem ceeb uas ua tau raws li cov qauv tsim (feem ntau Ntau dua lossis sib npaug li 15% rau cov qauv qauv thiab Ntau dua lossis sib npaug li 25% rau cov qauv tsim qauv). Tuam Tshoj cov ntxhua khaub ncaws ntxhua khaub ncaws ua lag luam tau pom qhov nruab nrab txhua xyoo kev loj hlob ntawm 27.2%, mus txog qhov kev lag luam loj ntawm kaum tawm txhiab nyiaj RMB hauv 2023. Los ntawm 2024, kev lag luam nkag mus rau cov qauv tsim tau nce mus txog 10.7%-txawm tias daim duab no tseem qis dua li 96% ntawm cov teb chaws Europe thiab North America tau pom zoo. Cov khoom lag luam no feem ntau pom muaj tus nqi biodegradability ntau tshaj 90%, thaum lawv cov neeg sawv cev pabcuam tau zoo cuam tshuam cov teebmeem tsis zoo uas calcium thiab magnesium ions hauv cov dej tawv tuaj yeem ua rau kev ua haujlwm ntxuav.
