Cov yam ntxwv ntawm cov khoom xyaw: "Qhov Tseeb" ntawm cov tshuaj tua kab mob maj mam
Polyhexamethylene Biguanide (PHMB) yog cov tshuaj tua kab mob cationic polymer. Nws cov qauv molecular zoo li "net," muaj peev xwm ntes tau cov kab mob thiab cov kab mob sai sai thaum cuam tshuam lawv cov cell membranes. Tsis zoo li cov khoom muaj zog oxidizing ntawm chlorine-raws li cov tshuaj tua kab mob (xws li "84" tshuaj tua kab mob), PHMB siv cov txheej txheem ntawm kev ua tau zoo, ua rau muaj kev puas tsuaj tsawg heev ntawm cov protein thiab fibers. Cov kev tshawb fawb soj ntsuam tau pom tias ntawm cov qauv siv ntau (0.02%-0.05%), PHMB nthuav tawm zoo li tsis muaj kev cuam tshuam rau cov ntaub xws li paj rwb thiab polyester. Nws qhov kev ruaj ntseg profile yog ntxiv underscored los ntawm nws cov kev koom tes nyob rau hauv kev sib cuag lens kev daws teeb meem.
Kev Siv Scenarios: Thaum Twg Khaub Ncaws "Poob"?
Txawm hais tias PHMB nws tus kheej maj mam, kev ceeb toom tseem ceeb hauv cov xwm txheej hauv qab no:
Kev siv tsis raug ntawm High Concentrations: Muab cov tshuaj tua kab mob ncaj qha rau hauv cov khaub ncaws (tshwj xeeb yog cov fibers zoo li cov paj rwb ntshiab lossis ntaub plaub)-los yog siv nws yam tsis muaj kev sib xyaw kom zoo- tuaj yeem ua rau qhov chaw khov lossis tawg vim qhov seem seem.
Kev Siv Ua Ke: Thaum siv ib txhij nrog enzyme-raws li cov ntxhua khaub ncaws los yog cov ntaub softeners, cationic xwm ntawm PHMB yuav txo tau me ntsis kev tu kom huv si; Txawm li cas los xij, nws tsis ncaj qha ua kev puas tsuaj rau cov fibers lawv tus kheej.
Cov Khoom Siv Tshwj Xeeb: Rau cov protein-raws li fibers xws li txhob lo lo ntxhuav thiab tawv, txhua yam tshuaj tua kab mob-xws li PHMB- yuav tsum tau siv nrog ceev faj heev. Txawm hais tias PHMB yog softer dua cawv, nws tseem pom zoo kom ua ib qho me me - thaj tsam kuaj ua ntej daim ntawv thov tag nrho.
Cov Tswv Yim Tiv Thaiv: 3 Lub Tswv Yim Los Tiv Thaiv "Cov Tshuaj Tiv Thaiv" rau khaub ncaws
Dilute Ua ntej siv: Dilute cov tshuaj nrog dej raws li qhov sib piv tau teev tseg hauv cov lus qhia khoom (feem ntau 1:200 txog 1:500). Txau cov khoom sib tov rau hauv cov khaub ncaws los yog cia cov khaub ncaws so rau 10-15 feeb, ces yaug kom huv si nrog dej huv.
Xaiv hom khoom tsim nyog: Ua ntej cov tshuaj tua kab mob tshwj xeeb tsim los siv rau ntawm khaub ncaws. Cov khoom no feem ntau muaj fiber ntau- tiv thaiv cov khoom ntxiv tsim los txo cov hluav taws xob zoo li qub thiab tiv thaiv cov ntaub los ntawm qhov tawv lossis tawv.
Kev Kho Mob Lub Hom Phiaj: Yog tias tsuas yog thaj chaw tshwj xeeb ntawm cov tsoos tsho yuav tsum muaj tshuaj tua kab mob (xws li, cuffs lossis necklines), siv cov paj rwb pad dipped rau hauv cov tshuaj diluted los so thaj tsam cuam tshuam, yog li zam qhov xav tau kom ntub tag nrho cov khaub ncaws.
Pro Tip: PHMB tswj kev ruaj ntseg ntau dua ntawm qhov kub qis dua 40 degree, vim tias qhov kub thiab txias tuaj yeem txo nws qhov ua tau zoo. Yog li ntawd, diluting cov tshuaj nrog cov dej sov so yields superior!
