I-Diethanolamine (i-Bis(beta-hydroxyethyl)amine)

Imvelo yamakhemikhali

I-Diethanolamine iyisisekelo se-organic esisetshenziswe njenge-emulsifying and dispersing agent. Ingasetshenziswa futhi njenge-baffer eyisisekelo, ene-pH efanele cishe nge-pH 9, uma ifakwe i-HCl noma enye i-asidi. Okunye ukusetshenziswa kufaka phakathi: "ukuhlafuna" amagesi, njenge-intermediate yamakhemikhali, njenge-humectant noma i-softening agent.

Izicelo

I-Diethanolamine efana ne-triethanolamine isetshenziswa njenge-surfactant. Iphinde ibe yisithiyo sokugqwala ngokusebenzisa i-chemisorption.

Ukuhlanza amagesi njengoba kuboniswe ngaphansi kwe-ethanolamine. I-Diethanolamine ingasetshenziswa namagesi aqhekekayo namagesi amalahle noma amafutha aqukethe i-carbonyl sulfide engasabela nge-monoethanolamine. Njengamakhemikhali erabha aphakathi nendawo. Ekwenziweni kwezinto ezisebenzayo ezingaphezulu ezisetshenziswa ezikhungweni zezindwangu, ama-herbicides, ama-petroleum demulsifiers. Njenge-emulsifier kanye ne-dispersing agent kumakhemikhali ahlukahlukene ezolimo, izimonyo, kanye nemithi. Ekukhiqizweni kwezinto zokugcoba embonini yezindwangu. Njenge-humectant kanye ne-softening agent. Ekwenziweni kwezinto eziphilayo.

I-Diethanolamine isetshenziswa ekukhiqizweni kwezinto ezisebenzayo ebusweni kanye nezinto zokugcoba embonini yezindwangu; njengesithako samakhemikhali erabha; njenge-emulsifier; njenge-humectant kanye ne-softening agent; njengesihlanzi kumapende, kuma-shampoo, nakwezinye izinto zokuhlanza; futhi njengesithako esiphakathi kwama-resins nama-plasticizer.

Ifomu elibonakalayo

Uketshezi olunamafutha olungenambala noma amakristalu amhlophe aqinile

Isikhathi sokuphelelwa yisikhathi

Ngokusho kokuhlangenwe nakho kwethu, umkhiqizo ungagcinwa izinsuku ezingu-12.izinyanga kusukela osukwini lokulethwa uma zigcinwe ezitsheni ezivalwe kahle, zivikelwe ekukhanyeni nasekushiseni futhi zigcinwe emazingeni okushisa aphakathi kuka-5 -30°C.
