Izilondolozi Zekhwalithi Ephezulu Dimethyloldimethyl Dmdm Hydantoin
Incazelo Yemikhiqizo
I-Organic compound eyingxenye yenhlanganisela eyaziwa ngokuthi ama-hydantoin. I-preservative esebenza kahle kakhulu yobubanzi obubanzi. Uketshezi olucacile. I-pH (njengoba injalo): 6.5-7.5. Okuqukethwe okusebenzayo 55.0 - 58.0%. Incibilika kalula emanzini.

Izinzuzo
- Ukulondolozwa okusebenzayo kwe-broad-spectrum ngokumelene nama-bacteria e-gram-positive kanye ne-gram-negative, imvubelo, kanye nesikhunta
- Ngokuncibilika kwayo okuhle kwamanzi, iphakanyiswa ikakhulukazi ukwakhiwa kwama-aqueous nama-emulsions
- Inweba impilo yeshelufu yemikhiqizo yokunakekelwa komuntu siqu ngokuvamile ibe yizinyanga ezingu-6-18
- Ihambisana nezithako eziningi zezimonyo
- Umkhiqizo awucasuli futhi awuzweli
- Inobungani nemvelo njengoba ingeke yakheke ezintweni eziphila emanzini futhi izobhidlizwa ama-microorganisms emhlabathini.
Sebenzisa
Izinga lokusetshenziswa elinconyiwe lika-0.1-0.6% (ligunyazwe ukusetshenziswa kufika ku-1% e-USA futhi kufike ku-0.6% eYurophu). Isebenza kahle kumazinga we-pH kufika ku-10 (i-pH ekahle 4-10). Inganezelwa ngokuqondile ekwakhiweni ngesikhathi sokwenziwa kwangaphambili noma ngemva kwe-emulsification ku-60°C/140°F noma ngaphansi. Okokusetshenziswa kwangaphandle kuphela.
Izinhlelo zokusebenza
Zonke izinhlobo zemikhiqizo yokunakekelwa kwesikhumba nezinwele, izinto zokusula, imikhiqizo yokunakekelwa kwelanga, nemikhiqizo yezimonyo.
