Isingeniso
I-methyl hydrogen azelate, eyaziwa nangokuthi i-polycarboxylate, iyi-polymer ebaluleke kakhulu yamangqamuzana. Inezici ezilandelayo:
1. Izakhiwo zomzimba: I-methyl hydrogen i-azelate iwuketshezi oluphuzi olukhanyayo olungenambala noma olukhanyayo, olunokuncibilika okuhle, luncibilika emanzini, utshwala nezincibilikisi zemvelo.
2. Izakhiwo zamakhemikhali: i-methyl hydrogen azelate iyinhlanganisela ye-ester enokuqina okuphezulu kanye nokumelana namakhemikhali. Ingenziwa nge-hydrolyzed ibe yi-azelaic acid ne-methanol.
Ukusetshenziswa okuyinhloko kwe-methyl hydrogen azelate kufaka:
1. Ukulungiswa kwe-polymer: i-methyl hydrogen azelate ingenziwa i-polymerized namanye ama-monomers ukuze kulungiswe ama-polymer amangqamuzana aphezulu. Lawa ma-polymers anezakhiwo ezinhle kakhulu futhi angasetshenziswa ezimbonini ezahlukahlukene ezinjengokumboza, iglue, amapulasitiki, imicu, njll.
2. I-Surfactant: I-methyl hydrogen azelate ingasetshenziswa njenge-emulsifier, i-disperant kanye ne-ejenti yokumanzisa, isetshenziswa kakhulu kuzimonyo, okokuhlanza kanye nemikhiqizo yokunakekelwa komuntu siqu kanye neminye imikhakha.
Izindlela zokulungiselela i-methyl hydrogen azelate ikakhulukazi zimi kanje:
1. Ukusabela kwe-Transesterification: ukusabela kwe-transesterification kwenziwa nge-nonyl alcohol kanye ne-methyl formate phambi kwe-acid catalyst ukuze kutholwe i-methyl hydrogen azelate.
2. Ukusabela kwe-esterification okuqondile: i-esterification ye-nonanol kanye ne-formate ngaphansi kwesenzo se-acid catalyst ukukhiqiza i-methyl hydrogen azelate.
Qaphela ulwazi olulandelayo lokuphepha lapho usebenzisa futhi uphatha i-methyl hydrogen azelete:
1. I-methyl hydrogen azelate iyacasula futhi kufanele ihashazwe ngokushesha lapho ithinta isikhumba namehlo.
2. Gwema ukuhogela umhwamuko we-methyl hydrogen azelate futhi uwusebenzise endaweni enomoya omuhle.
3. I-methyl hydrogen azelate inobuthi obuphansi, kodwa ukuchayeka kwesikhathi eside nokukhulu kungase kube nomthelela empilweni, futhi ukuchayeka ngokweqile kufanele kugwenywe.
4. Lapho ugcina futhi uhambisa i-methyl hydrogen azelate, igcine kude nomlilo kanye nezinga lokushisa eliphezulu ukuze uvimbele ingozi yokusha nokuqhuma.
Sicela uqaphele ukuthi ngaphambi kokusebenzisa i-methyl hydrogen azelate nanoma iyiphi ikhemikhali, kufanele ufunde ngokucophelela futhi ulandele izinqubo zokuphepha ezifanele.
