DMDM hydantoin, tseem hu ua dimethyloldimethyl hydantoin, yog ib qho tshuaj tiv thaiv zoo nkauj uas siv rau hauv ntau yam khoom siv tu tus kheej. Nws qhov sib xws nrog ntau yam tshuaj pleev ib ce ua rau nws yog qhov kev xaiv zoo rau ntau tus neeg tsim tshuaj. Nov yog qee qhov laj thawj tseem ceeb vim li cas DMDM hydantoin ua rau pom kev sib xws zoo hauv cov tshuaj pleev ib ce:
Ntau yam pH dav: DMDM hydantoin ua haujlwm tau zoo hla ntau yam pH, ua rau nws tsim nyog rau cov qauv nrog ntau qib pH sib txawv. Nws tseem ruaj khov thiab ua haujlwm tau zoo hauv ob qho tib si acidic thiab alkaline mob, ua kom ntseeg tau tias kev khaws cia txhim khu kev qha hauv ntau yam khoom siv pleev ib ce.
Kev Sib Tw Nrog Cov Khoom Xyaw Sib Txawv:DMDM hydantoinqhia tau tias nws sib haum nrog ntau yam khoom xyaw pleev kom zoo nkauj, suav nrog cov emulsifiers, surfactants, humectants, thickeners, thiab cov tshuaj sib xyaw ua ke. Qhov kev hloov pauv no tso cai rau cov neeg tsim cov tshuaj kom muab DMDM hydantoin rau hauv ntau hom tshuaj yam tsis muaj kev txhawj xeeb txog kev sib cuam tshuam ntawm cov khoom xyaw.
Kev Ruaj Ntseg Thermal: DMDM hydantoin ua rau muaj kev ruaj ntseg zoo heev, khaws cia nws cov khoom tiv thaiv txawm tias nyob rau hauv qhov kub siab. Tus cwj pwm no yog qhov tseem ceeb tshwj xeeb thaum lub sijhawm tsim khoom uas muaj kev ua kom sov lossis txias cov tshuaj pleev ib ce.
Yaj hauv dej: DMDM hydantoin yaj tau hauv dej heev, uas ua rau nws yooj yim rau hauv cov tshuaj pleev ib ce xws li tshuaj pleev, tshuaj pleev, tshuaj zawv plaub hau, thiab tshuaj ntxuav lub cev. Nws tawg thoob plaws hauv cov tshuaj, ua kom ntseeg tau tias kev khaws cia zoo thoob plaws hauv cov khoom.
Cov roj-Hauv-Dej thiab Dej-Hauv-Roj Emulsions: DMDM hydantoin siv tau rau hauv ob qho tib si roj-hauv-dej (O/W) thiab dej-hauv-roj (W/O) emulsion systems. Qhov kev ywj pheej no tso cai rau cov neeg tsim qauv siv nws hauv ntau yam khoom siv pleev ib ce, suav nrog cov tshuaj pleev ib ce, tshuaj pleev ib ce, lub hauv paus, thiab tshuaj pleev thaiv hnub.
Kev Sib Tw Nrog Cov Tshuaj Tsw Qab:DMDM hydantoinNws sib xws nrog ntau yam tshuaj tsw qab, ua rau nws siv tau rau hauv cov tshuaj pleev ib ce uas muaj ntxhiab tsw qab. Nws tsis cuam tshuam rau qhov tsw qab lossis kev ruaj khov ntawm cov roj tsw qab, ua rau cov neeg tsim cov tshuaj muaj peev xwm tsim cov khoom zoo nkauj thiab tsw qab ntev.
Kev Ruaj Ntseg ntawm Cov Tshuaj: DMDM hydantoin pab txhawb rau kev ruaj ntseg ntawm cov tshuaj pleev ib ce los ntawm kev tiv thaiv kev loj hlob ntawm cov kab mob thiab tswj cov khoom kom zoo. Nws qhov sib xws nrog lwm cov khoom xyaw pab ua kom cov khoom pleev ib ce tseem muaj kev nyab xeeb thiab ua tau zoo thoob plaws nws lub neej txee.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov yam ntxwv ntawm cov tshuaj thiab cov khoom xyaw tshwj xeeb tuaj yeem cuam tshuam rau qhov sib xws ntawm DMDM hydantoin hauv cov tshuaj pleev ib ce. Nws ib txwm raug nquahu kom ua qhov kev ntsuam xyuas sib xws thiab sab laj nrog cov lus qhia thiab cov cai kom ntseeg tau tias siv DMDM hydantoin kom raug thiab siv tau zoo hauv cov tshuaj pleev ib ce tshwj xeeb.
