Lo mkhiqizo ungu-55% wesisombululo samanzi se-DMDMH, usebenzisa ifomula yakamuva yokukhiqiza yamazwe ngamazwe nobuchwepheshe. Ilawulwa ngokuqinile ngabasebenzi bobuchwepheshe obuphezulu besikhungo se-R&D, ikhwalithi inokwethenjelwa, ukuhambisana kuhle, futhi umphumela uhlala isikhathi eside ngaphandle kokuphazamisa umkhiqizo Ukubukeka, iphunga kanye nokusebenza. Iphephile futhi ayinabo ubuthi. Ingasetshenziswa kububanzi obubanzi be-PH=5-12. Iyawasha, i-emulsion Kuyi-antiseptic efanelekile kanye ne-antibacterial ejenti yezimonyo ezifana, ukhilimu, njll.

Isici

Ukusebenza kahle kakhulu, isibulala-sikhunta esishibhile, kulula ukusisebenzisa, sincibilika kalula emanzini naseziphuzweni ezidakayo eziphansi, futhi zizinzile emanzini nesigaba se-emulsion samafutha. Ihambisana nama-cationic, anionic kanye nama-nonionic surfactants, ama-emulsifiers namaprotheni. Iyazinzile ngokuhamba kwesikhathi, i-pH ebanzi kanye nebanga lokushisa.

Ukusetshenziswa okuphakanyisiwe

Ngenxa yokuncibilika kwayo okuyingqayizivele kwamanzi, i-DMDMH ingangezwa kokhilimu kanye nezakhi zokunakekelwa komuntu siqu zokuwasha ngokugxila kuka-0.2~0.6%. Uma i-DMDMH yengezwa ku-surfactant, izinga lokushisa layo livamise ukuba ngu-50℃~60℃, futhi i-pH iphakathi kuka-7.5~8.5. Njengoba izithako kanye nokwakhiwa kwemikhiqizo yokunakekelwa komuntu siqu kwehluka kakhulu, okungase kuthinte ukusebenza kahle kwezivimbelakuvunda, sincoma ngokuqinile ukuthi uqinisekise ukusebenza nokuqina kwe-DMDMH ngaphambi kokukhiqizwa.
