I-Hydroxypropyl Methylcellulose (HPMC) i-celluble celluble cellulose esetshenziswa kabanzi emkhakheni wezinto zokwakha, ikakhulukazi ngodaka, lapho indima yayo ibaluleke kakhulu khona. Njengomuntu osebenza kahle kanye ne-ejenti ye-gelling, i-hpmc ingathuthukisa kakhulu ukusebenziseka, ukugcinwa kwamanzi kanye nezinye izakhiwo zodaka, ngaleyo ndlela kuthuthukise ukusebenza kahle kodaka nokwakha kodaka.
(1) Izici eziyisisekelo ze-HPMC
I-HPMC iyindawo eyi-cellulose etholwe ngokuguqulwa, ikakhulukazi eyakhiwa nge-cellulose ngemuva kwe-hydroxypropylation ne-methylation. I-HPMC ine-solubility enhle kakhulu yamanzi, ukuqina okushisayo kanye nokuqina kwamakhemikhali. Kungakha isixazululo esiphakeme esivelele emanzini, esidlala indima ekukhulekeni, okunomswakama nokwenza ngcono uketshezi. Ngaphezu kwalokho, i-HPMC nayo inomthelela omuhle ekunamatheleni, ukugcinwa kwamanzi noketshezi lodaka.
(2) Umphumela we-HPMC ekusebenzeni kodaka
1. Ukwenza ngcono uketshezi
U-Fluity of Motar uyinkomba ebalulekile yokuhlola ukusebenziseka kwayo. Udaka olunobunzima obumpofu luzoholela ebunzimeni bokwakha, ikakhulukazi ezindaweni lapho kusetshenziswa khona isicelo esikhulu noma izidingo zokwakha eziphakeme. I-HPMC inyusa i-visarcosion yodaka, okwenza kube ngoketshezi oluningi ngesikhathi sokusetshenziswa, okusiza ukufaka ngokulinganayo nokulawula ubukhulu ngesikhathi sokwakha. Ikakhulu ekwakhiweni kodaka okuwugqinsi, i-hpmc inganciphisa ngempumelelo ukulimala okuthe mpo kokuqukethwe futhi ilondoloze ukuqina kodaka, ngaleyo ndlela kuqinisekiswe ukuthi udaka alugelezi noma luvikeleke ngaphambi kwesikhathi, ukugwema izindawo ezingalingani.
2. Thuthukisa ukugcinwa kwamanzi
Ukugcinwa kwamanzi kodaka kubalulekile ekusebenzeni ngesikhathi sokwakha, ikakhulukazi ekuxubeni, uhlelo lokusebenza kanye nezigaba ezinzima. Uma amanzi odongeni ukhipha ngokushesha okukhulu, kuzodala izinkinga ezinjengokuqhekeka komhlaba kanye nokunamathelisa. Njenge-ejenti esebenza kahle yokugcina amanzi, i-HPMC ingathuthukisa kakhulu ukugcinwa kwamanzi ngodaka lwamanzi, yehlisa izinga lokuhwamuka kwamanzi, gcina owesimame ngesikhathi sokwakha, futhi uthuthukise amandla okuvinjwa kodaka.
3. Ukunamathela okuthuthukisiwe
Ukunamathenjwa kodaka kuthinta ngqo umphumela wokwakha, ikakhulukazi isibopho sezinto ezifana namathayili namatshe. I-HPMC ithuthukisa ukwakheka kanye nezakhiwo zembongo zodaka, okuvumela udaka ukuze ahambisane kangcono ne-substrate futhi athuthukise amandla okubopha phakathi kodaka nobuso. Lokhu kubaluleke kakhulu ekwakhiweni kodonga, phansi, izimbotshana zangaphandle zodonga, njll., Futhi kungagwema ngempumelelo into yento yokuwa ngenxa yokubopha okubuthakathaka ngemuva kokwakhiwa.
4. Thuthukisa ukumelana nokulwa nokuqhekeka nokuqhekeka
I-HPMC kuDinga ingathuthukisa ukumelana nokulwa nodaka okuwa nokuqhekeka, ikakhulukazi endaweni enomswakama noma imvelo ephezulu yokushisa. I-HPMC ayikwazi ukwenza ngcono amandla okugcina okubopha ngodaka, kepha futhi yakha isakhiwo esifanayo ngesikhathi senqubo yodaka yodaka, ukunciphisa ubungozi bokuqhekeka okubangelwa ukuhwamuka okusheshayo kwamanzi noma izinguquko zokushisa.
(3) Ukusetshenziswa kwe-HPMC ngezinhlobo ezahlukene zodaka
1. Bopha ngodaka
EBonding Data, umsebenzi oyinhloko we-HPMC ukwenza ngcono amandla e-bonding, ukuze udaka lukwazi ukuhlanganisa ukusebenza ngempumelelo kodaka, kodwa nokwenza kube lula ukusebenza ngodaka, okwenza kube lula ukusebenza ngodaka, okwenza kube lula ukusebenza kwezitini, okwenza kube lula ukuthi abasebenzi bezokwakha basebenzise futhi balungise isikhundla sezitini.
2. Ukulungiswa kokulungiswa kodaka
Ngokulungiswa kokulungiswa kwe-crack, i-HPMC ingakhuphula ngempumelelo ukugcinwa kwamanzi noketshezi lodaka, ngaleyo ndlela iqinisekise ukuthi imifantu ngemuva kokulungiswa kwemali ingagcwaliswa ngokulinganayo futhi ilondoloze isibalo esihle. Izakhiwo ezikhulisa ze-HPMC zingavimbela udaka ukuthi ageleze ngokushesha kakhulu ngesikhathi sokwakha, eqinisekisa ukuqina komthelela wokulungisa.
3. Ukunamathisela udaka
Ngokudluliswa kwezinto ezifana nama-tile namatshe, i-HPMC ingathuthukisa amandla okuqala abopha kanye nokukhohlisa kodaka. Njengoba ukusebenziseka okufanele kodaka kudinga ukunakekelwa isikhathi eside ngesikhathi sokwakha, i-HPMC ingagcina ukusetshenziswa kodaka isikhathi eside futhi kunciphise inkinga yokomiswa kwe-data
I-4
Udaka odongeni lwangaphandle ludinga ukubekezelela izinguquko eziyinkimbinkimbi zemvelo, njengokuguquguquka kwemvula, ukuqina kwemvula, ukuqina kodonga olude ngaphandle kosuku lokukhangisa, ukumelana nokuqhekeka kodaka, ukugwema ukumelana noma ukuqhekeka.
(4) Izinyathelo zokuphepha ekusetshenzisweni kwe-HPMC
Yize umphumela wohlelo lokusebenza lwe-HPMC ku-motar ubalulekile, ukusetshenziswa kwayo kubuye kudinga izidingo ezithile zobuchwepheshe. Isibonelo, inani le-HPMC elingeziwe kufanele liguqulwe ngokuya ngezidingo zangempela zodaka. Ukusetshenziswa ngokweqile kungadala ukuba i-visar viscosity ibe phezulu kakhulu, okuthinta umsebenzi wokwakha. Ukusetshenziswa okunganele kungahle kube nomphumela wokuthuthukisa ukusebenza kodaka akubonakali. Ngaphezu kwalokho, i-HPMC iyancibilika kancane. Kunconywa ukuyixuba ngamanzi ngaphambi kokusebenzisa ukugwema ukubonakala kwezinto ezinamandla ezithinta ikhwalithi yodaka.
Ukusetshenziswa kwe-HPMC kuDingarst kuthuthukisa ukusebenza kodaka kodaka, kuthuthukisa ubungako, ukugcinwa kwamanzi, ukunqwabelana kanye nokuvikelwa kodaka, futhi kunika amandla udaka ukuba alondoloze ukusebenza okuhle ezindaweni ezahlukahlukene zokwakha. Ngokuthuthuka okuqhubekayo kwezidingo zemboni yezokwakha zokusebenza kahle kwezokwakha kanye nekhwalithi, i-HPMC, njengezengezo ezisebenzayo nezemvelo, zizoba nethemba lesicelo ebanzi.
