I-1. Indalo yendalo
Izinto ezisisiseko zeI-HPMCNgaba i-sellyulose yendalo, edla ngokufumaneka kwi-Pulp yeWood okanye i-Cotton Pulp. Ezi fibers zendalo ziqulethe inani elikhulu leeyunithi ze-β-glucose kwaye zisisiseko esiphambili sokuveliswa kwe-HPMC. I-cottuloty ecocekileyo ecocekileyo isetyenziswa rhoqo ekuvelisweni kwe-HPMC ekumgangatho ophezulu ngenxa yomxholo ophantsi.
2. Isodium hydroxide (NaOH)
I-Sodium hydroxide (i-nah) iyafuneka ukuze iphinde iqale kwaye iphumelele i-seluplose. Imisebenzi yayo ephambili ibandakanya:
Ukudumba iimolekyuli zeseluplose kunye nokwandisa umsebenzi wokuphendula;
Ukutshabalalisa indawo ye-crystalline ye-selsulose ukwenza kube lula ukuba enze isigqibo sokuphendula;
Ukukhuthaza ubume bemithi elandelayo kunye nokuphendula kwe-hydroxypropypropy.
I-3. I-Methyl Chloride (Ch₃cl)
I-Methyl Chloride (i-methyl chloride) yinkqubo ephambili yokuphinda kwenziwe kwi-methylid yokuphendula kwi-Kimbacell® yemveliso. I-idilesi ye-alkal ye-alkal ukuze ithathe indawo yokutshintsha amaqela e-hydroxyl (--------------the)I-Methyl Selelose (MC), ngaloo ndlela kuphucule ukunyibilikisa kunye neepropathi zomzimba kunye neekhemikhali ze-sellulose.
I-4. I-propylene oxide (c₃h₆o)
I-propylene oxide isetyenziswa kwi-hydroxyproplopypropy, enokwazisa i-hydroxypropyl Ukuqaliswa kwe-hydroxypropy yakho:
QAPHELA ukuphucula ukubethwa kwamanzi kwe-HPMC;
Ukuphucula i-viscofity kunye nepropathi ye-suloology yesisombululo sayo;
Ukuphucula uzinzo kwalo kubushushu obahlukeneyo.
I-5. Isinyibilikisi (amanzi okanye i-organic selvent)
Amanzi okanye i-orgaccent selvent (ezinjengeSopropanol, iMethanol, njl.njl.) Isetyenziswa njengokuphendula kwimveliso yokuncedisa ukudityaniswa kwezixhobo kunye nokulawula. Ukongeza, ezinye izicombulo zisetyenziselwa ukususa iimveliso ezingasetyenziswanga kwimveliso elandelayo kunye nokuhlamba ukuze kuqinisekiswe ubunyulu bemveliso.
I-6. I-acidic okanye i-alkaline catalyst
Ukwenzela ukuba uqhubekeke neemeko zokuphendula kunye nokuphucula ukusebenza kwe-E-AChenter, i-acidic okanye i-alkaline catalysbonate (Nahco₃) okanye i-ANODIIC BID
7. Ezinye izinto ezincedisayo ezincedisayo
Abanye abantu abazinzileyo, oovimba okanye ezinye iichemicals zinokusetyenziswa kwinkqubo yemveliso yokuphucula umgangatho we-HPMC, ukuphucula uzinzo, kunye nokulawula iipropathi zayo zomzimba kunye nezikhewu.
I-kimbacell®hpmc iveliswa ikakhulu yi-alkalization, i-methyling kunye ne-hydroxyyprocy ye-seluplose yendalo.Izinto zayo ezibukhali zibandakanya:
I-seluplose yendalo (ikakhulu ivela kwi-pulp yenkuni okanye i-cotton ehlaziyiweyo)
I-Sodium hydroxide (i-nah) (ye-alkalization)
I-Methyl Chloride (Ch₃cl) (ye-methyting)
I-propylene oxide (c₃h₆o) (ye-hydroxyypropy)
Amanzi okanye i-solforpec solvent (yokuphendula kunye nokuhlamba)
I-Catalysts kunye ne-Statilibers (yokuphendula okuqinisekileyo)
I-HPMC isetyenziswa ngokubanzi kumashishini amaninzi anje ngamayeza, ukwakhiwa, ukutya, kunye neepasethi ngenxa yokuzola kwamanzi amanzi, ubuchule bokuhlengahlengiswa kobuchule kunye nokulungelelaniswa kwe-viscosity kunye nokulungelelaniswa kwe-viscosity kunye ne-bi viomity.
