Cov lus qhia:
Txij li thaum dichlosan muaj cov solubility tsawg hauv dej, nws yuav tsum tau yaj hauv cov concentrated surfactants nyob rau hauv cov cua kub yog tias tsim nyog.Tsis txhob raug qhov kub thiab txias> 150 ° C.Yog li ntawd, nws raug nquahu kom ntxiv cov hmoov ntxhua tom qab ziab hauv cov tshuaj tsuag ntauwd.
Dichlosan tsis ruaj khov hauv cov qauv uas muaj TAED reactive oxygen bleach.Cov lus qhia tu cov cuab yeej:
Cov cuab yeej siv los tsim cov khoom siv diclosan tuaj yeem ntxuav tau yooj yim siv cov concentrated surfactants thiab tom qab ntawd yaug nrog dej kub kom tsis txhob DCPP nag lossis daus.
Dichlosan yog muag raws li biocidal active tshuaj.Kev ruaj ntseg:
Raws li peb cov kev paub dhau los xyoo dhau los thiab lwm cov ntaub ntawv muaj rau peb, diclosan tsis ua rau muaj kev phom sij rau kev noj qab haus huv yog tias nws siv kom raug, kev saib xyuas raug them rau cov kev ceev faj uas yuav tsum tau tswj cov tshuaj, thiab cov ntaub ntawv thiab cov lus pom zoo muab hauv peb. cov ntaub ntawv kev nyab xeeb tau ua raws.
Daim ntawv thov:
Nws tuaj yeem siv los ua tshuaj tua kab mob thiab tshuaj tua kab mob hauv thaj chaw ntawm cov khoom kho tus kheej lossis tshuaj pleev ib ce.Buccal tshuaj tua kab mob.
