Cov Lus Qhia:
Vim tias dichlosan yaj tau yooj yim hauv dej, nws yuav tsum tau yaj rau hauv cov surfactants uas muaj concentrated nyob rau hauv qhov kub thiab txias yog tias tsim nyog. Tsis txhob cia nws kub dhau >150°C. Yog li ntawd, nws raug pom zoo kom ntxiv cov hmoov ntxhua khaub ncaws tom qab ziab hauv lub tshuab txau.
Dichlosan tsis ruaj khov hauv cov qauv uas muaj TAED reactive oxygen bleach. Cov lus qhia ntxuav khoom siv:
Cov khoom siv siv los tsim cov khoom muaj diclosan tuaj yeem ntxuav tau yooj yim siv cov surfactants concentrated thiab tom qab ntawd yaug nrog dej kub kom tsis txhob muaj DCPP nag.
Dichlosan raug muag ua ib yam khoom siv tua kab mob. Kev Ruaj Ntseg:
Raws li peb qhov kev paub dhau los ntau xyoo thiab lwm cov ntaub ntawv muaj rau peb, diclosan tsis ua rau muaj kev phom sij rau kev noj qab haus huv tsuav yog siv nws kom raug, kev saib xyuas zoo rau cov kev ceev faj uas yuav tsum tau ua rau kev siv cov tshuaj, thiab cov ntaub ntawv thiab cov lus qhia muab rau hauv peb cov ntawv qhia kev nyab xeeb raug ua raws.
Daim Ntawv Thov:
Nws tuaj yeem siv ua tshuaj tua kab mob thiab tshuaj tua kab mob hauv cov teb ntawm cov khoom siv kho mob tus kheej lossis cov tshuaj pleev ib ce. Cov khoom siv tua kab mob hauv qhov ncauj.
