Lokhu kubuyekezwa okuphelele kuhlola indima enezici eziningi ze-hydroxypropyl methylcellulose (HPMC) ekuthuthukiseni izakhiwo zokubopha nokunamathisela udaka.I-HPMC iwukuphuma kwe-cellulose esithole ukunakwa okusabalele embonini yezokwakha ngenxa yezakhiwo zayo ezihlukile njengokugcina amanzi, ukujiya, kanye nokusebenza okuthuthukisiwe.
ethula:
1.1 Isendlalelo:
Imboni yezokwakha iyaqhubeka nokufuna izixazululo ezintsha zokwenza ngcono ukusebenza kwezinto zokwakha.I-HPMC, etholakala ku-cellulose, ivele njengesengezo esithembisayo sokuthuthukisa izakhiwo zokuhlanganisa nokunamathisela udaka.Lesi sigaba sihlinzeka ngemininingwane yezinselele ezibhekene nodaka olujwayelekile futhi sethula amandla e-HPMC okubhekana nalezi zinselele.
1.2 Izinjongo:
Injongo eyinhloko yalokhu kubuyekezwa ukuhlaziya izakhiwo zamakhemikhali ze-HPMC, ukufunda ukusebenzisana kwayo nezingxenye zodaka, nokuhlola umphumela wayo ezimpahleni ezihlukahlukene zokuhlanganisa nokunamathisela udaka.Ucwaningo futhi lwaluhlose ukuhlola ukusetshenziswa okungokoqobo nezinselelo zokufaka i-HPMC ekwakhekeni kodaka.
Ukwakheka kwamakhemikhali kanye nezakhiwo ze-HPMC:
2.1 Ukwakheka kwamangqamuzana:
Lesi sigaba sihlola ukwakheka kwamangqamuzana e-HPMC, sigxile emaqenjini asemqoka asebenzayo anquma izici zayo eziyingqayizivele.Ukuqonda ukwakheka kwamakhemikhali kubalulekile ekubikezeleni ukuthi i-HPMC izosebenzisana kanjani nezingxenye zodaka.
2.2 Izici ze-Rheological:
I-HPMC inezici ezibalulekile ze-rheological, ezithinta ukusebenza nokuvumelana kodaka.Ukuhlaziywa okujulile kwalezi zakhiwo kunganikeza ukuqonda endimeni ye-HPMC ekwakhiweni kodaka.
Ukusebenzisana kwe-HPMC nezingxenye zodaka:
3.1 Izinto zikasimende:
Ukusebenzisana phakathi kwe-HPMC nezinto zikasimende kubalulekile ekunqumeni amandla ebhondi nokuhlangana kodaka.Lesi sigaba sicubungula izindlela ezingemuva kwalokhu kusebenzisana kanye nomthelela wako ekusebenzeni okuphelele kodaka.
3.2 Ama-aggregate nama-filler:
I-HPMC iphinde ihlanganyele nama-aggregate nama-filler, okuthinta izici zemishini zodaka.Lokhu kubuyekezwa kuhlola umphumela we-HPMC ekusabalaliseni lezi zingxenye kanye negalelo layo emandleni odaka.
Umthelela ekusebenzeni kodaka:
4.1 Ukunamathela nokubumbana:
Ukunamathela kanye nokubumbana kwezinsimbi zokubopha kanye nokuplasta kubalulekile ekwakhiweni okuhlala isikhathi eside nokuthembekile.Lesi sigaba sihlola umthelela we-HPMC kulezi zakhiwo futhi sidingida izindlela ezifaka isandla ekwenzeni ngcono ukunamathela.
4.2 Ukwakhiwa:
Ukusebenza kuyisici esibalulekile ekusetshenzisweni kodaka.Umthelela we-HPMC ekusebenzeni kodaka uyahlolwa, okuhlanganisa nomthelela wawo ekusetshenzisweni kalula nasekuqedeni.
4.3 Amandla kagesi:
Iqhaza le-HPMC ekwenzeni ngcono amandla omshini wodaka laphenywa kucatshangelwa umphumela wawo emandleni acindezelayo, aqinile kanye naguquguqukayo.Ukubuyekeza kuphinde kudingide imithamo elungile ye-HPMC ukuze kuzuzwe umfutho ofunekayo.
Ukuqina Nokumelana:
5.1 Ukuqina:
Ukuqina kodaka kubalulekile ukuze umelane nezimo zemvelo kanye nokugcina ubuqotho besakhiwo esikhathini eside.Lesi sigaba sihlola ukuthi i-HPMC ingathuthukisa kanjani ukuqina kwebhondi kanye nodaka lokuplasta.
5.2 Ukumelana nezinto zangaphandle:
I-HPMC kuxoxwa ngayo ukuze kuthuthukiswe ikhono lodaka lokumelana nezinto ezifana nokungena kwamanzi, ukuchayeka kwamakhemikhali, kanye nokushintsha kwezinga lokushisa.Lokhu kubuyekezwa kuhlola izindlela i-HPMC eyi-ejenti yokuvikela ephumelelayo.
Uhlelo Olusebenzayo Nomhlahlandlela Wokusungula:
6.1 Ukuqaliswa okungokoqobo:
Ukusetshenziswa okungokoqobo kwe-HPMC ekuhlanganiseni nasekwakheni udaka kuyahlolwa, kugqanyiswe izifundo eziyimpumelelo futhi kubonise ukuthi kungenzeka yini ukufaka i-HPMC kumaphrojekthi wokwakha.
6.2 Ukuthuthukiswa kwemihlahlandlela:
Imihlahlandlela yokwenza ama-mortars nge-HPMC inikeziwe, kucatshangelwa izici ezifana nomthamo, ukuhambisana nezinye izithasiselo, nezinqubo zokukhiqiza.Kuxoxwa ngeziphakamiso ezisebenzayo zokuthola imiphumela emihle.
Izinselelo namathemba esikhathi esizayo:
7.1 Izinselelo:
Lesi sigaba sidingida izinselele ezihambisana nokusetshenziswa kwe-HPMC emathafeni, okuhlanganisa ukonakala okungaba khona kanye nemikhawulo.Amasu okunqoba lezi zinkinga axoxa ngezinselele.
7.2 Ukubukeka Kwekusasa:
Ukubuyekezwa kuphetha ngokuhlola intuthuko yesikhathi esizayo engaba khona ekusetshenzisweni kwe-HPMC ekuhlanganiseni nasekufakeni udaka.Izindawo zocwaningo olwengeziwe kanye nokuqanjwa okusha kukhonjwa ukuze kuthuthukiswe izinsiza zokwakha.
