I-Cellulose Tashers (Mhec)

Methyl hydroxyethyl cellulose(Mhec) uhlobo lwe-cellulose ether esetshenziswa kabanzi kwizimboni ezahlukahlukene zezakhiwo zayo eziguquguqukayo. Nasi isibukezo se-MHEC:

Isakhiwo:

I-MHEC i-ether eguquliwe etholwa ethathwe ku-cellulose ngokusebenzisa uchungechunge lokuphendula kwamakhemikhali. Ibonakala ngokuba khona kwamaqembu we-methylyeth kanye ne-hydroxyethyls kwi-cellulose backbone.

Izakhiwo:

1. I-Solubinity yamanzi: I-MHEC iyanyibilika emanzini abandayo, yakha izixazululo ezicacile nezibonakalayo.
2. Ukuqina: Kukhombisa izakhiwo ezinhle kakhulu zokuqina, okwenza kubalulekile njengokushintsha kwe-Rheology ngezindlela ezahlukahlukene.
3. Ukwakheka kwamafilimu: I-MHHEC ingakha amafilimu aguquguqukayo futhi ahambisane namafilimu, afaka isandla ekusetshenzisweni kwawo kuzimbali kanye nama-adhesives.
4. Ukuzinza: Kunikeza ukuqina emamukeni kanye nokumiswa, ukuthuthukisa impilo yeshelufu yemikhiqizo eyenziwe.
5. I-Adhesion: I-Mhec yaziwa ngezakhiwo zayo ezinamathela, ifaka isandla ekunamathisweni okuthuthukile kuzicelo ezithile.

Izicelo:

1. Imboni Yokwakha:
   • Ama-Tile anamathela: I-MHEC isetshenziswa ezinamathekisayo zokuthuthukisa ukusebenza, ukugcinwa kwamanzi, nokunamathela.
   • Bokamezo kanye noDinder: Kuqashwa ku-Cement-based Marians kanye ne-Render ukuthuthukisa ukugcinwa kwamanzi nokusebenza kwamanzi.
   • Amakhompiyutha okuzimela: I-MHEC isetshenziswa kumakhompiyutha wokuzenzisa ezinhlaka zawo zokuqina nokuzinza.
2. Imidwebo nopende:
   • I-MHEC isetshenziswa kupende osuselwa emanzini kanye nokumbona njengomkhulu kanye ne-stabilizer. Inomthelela ekudleni okuthuthukile kanye nokusebenza okuphelele kwe-coating.
3. Adhesives:
   • I-MHEC isetshenziswa ekunamatheleni okuhlukahlukene ukuze ithuthukise ukunamathela futhi ithuthukise izakhiwo zesimbozo sokwenza okunamathelayo.
4. Izemithi:
   • Emikhakheni, i-Mhec isetshenziswa njenge-binder, ukuqhelelana ne-ejenti eyakha amafilimu ekusungulweni kwethebhulethi.

Inqubo Yokukhiqiza:

Ukukhiqizwa kwe-MHEC kufaka phakathi ukusheshisa kwe-cellulose ngenhlanganisela ye-methyl chloride ne-ethylene oxide. Imibandela ethile nezilinganiso ze-realent zilawulwa ukuze kufinyelelwe degree degree yokufaka esikhundleni (DS) kanye nokuvumelanisa izakhiwo zomkhiqizo wokugcina.

Ikhwalithi yokulawula:

Izindlela zokulawula ezisezingeni eliphakeme, kufaka phakathi amasu wokuhlaziya afana ne-pucletic magnetic resonance (NMR) Spectroscopy, aqashwa ukuqinisekisa ukuthi izinga lokufaka esikhundleni sebubanzi liphakathi kwebanga elithile nokuthi umkhiqizo uhlangabezana namazinga adingekayo.

Ukuguquguquka okuguquguqukayo kwe-MHEC kwenza kube yisithako esibalulekile ekwakhiweni okuhlukahlukene, okufaka isandla ekusebenzeni ngcono kwezinto zokwakha, ukumboza, ukunamathela, kanye nemithi. Abakhiqizi banganikeza amamaki ahlukene we-MHEC ukuze ahlangabezane nezidingo ezahlukahlukene zezimboni ezahlukahlukene.
