Ukugcinwa kwamanzi kanye nomgomo we-HPMC cellulose ether

Omunye wemisebenzi eyinhloko ye-hydroxypropylmethylcellulose (HPMC) cellulose ethers iwukuqina kanye nokuqiniswa ezintweni zokwakha, ukudla kanye nemikhiqizo yokunakekelwa komuntu siqu. Kodwa-ke, iphinde idlale indima ebalulekile ekuthuthukiseni ukugcinwa kwamanzi ezinhlelweni eziningi, okuhlanganisa ukunamathela kwamathayili, ama-grouts kanye nodaka olusekelwe kusimende.

Ukugcinwa kwamanzi kuchazwa njengekhono lento ethile yokugcina noma ukugcina amanzi engeziwe. Uma into ethile ingawagcini amanzi, ingabangela ukomisa noma ukuqhekeka, okuphazamisa ukusebenza kwayo konke.

Umgomo we-HPMC cellulose ether wokuthuthukisa ukugcinwa kwamanzi usekelwe esakhiweni sawo esiyingqayizivele samangqamuzana. I-HPMC cellulose ether iyi-polysaccharide polymer eyakhiwe amayunithi e-glucose axhunywe ngamabhondi e-β-(1,4)-glycosidic. Futhi iqukethe i-hydroxypropyl kanye namaqembu aseceleni e-methyl, awanika ukuncibilika kwamanzi kanye nezindawo zokugcina amanzi.

Lapho i-HPMC cellulose ether yengezwa odakeni olusekelwe kusimende, iqembu layo le-hydroxypropyl lizokhangiswa ebusweni bezinhlayiya zikasimende. Lokhu kudala ungqimba lwamanzi azungeze ama-pellets, okuvimbela ukuthi ome ngokushesha. Ngesikhathi esifanayo, iqembu le-methyl linikeza isithiyo esiqinile, ukuvimbela izinhlayiya zikasimende ekubopheni ngokuqinile futhi zakhe i-matrix eminyene. Lokhu kuvumela amanzi ukuthi asatshalaliswe kalula kulo lonke udaka, ukuthuthukisa ukusebenza kwawo, ukungaguquguquki nokusebenza kwawo jikelele.

Ukugcinwa kwamanzi kungakalwa kusetshenziswa izindlela ezihlukene, okuhlanganisa ukuhlola ukumunca kanye nokuhlola ukuhlanganisa i-centrifugation. Ukuhlolwa kokumuncwa kukala inani lamanzi into engakwazi ukubamba ngemva kokuvalelwa i-vacuum. Ukuhlolwa kwe-centrifuge kulinganisa inani lamanzi into engagcinwa ngemva kokuba ngaphansi kwamandla we-centrifugal. Lokhu kuhlola kusiza ukucacisa ukusebenza kahle kwe-HPMC cellulose ethers ekuthuthukiseni ukugcinwa kwamanzi ezinhlelweni ezithile.

Ngaphezu kokuthuthukisa ukugcinwa kwamanzi, i-HPMC cellulose ethers inikeza ezinye izinzuzo ezintweni zokwakha nezinye izinhlelo zokusebenza. Ithuthukisa ukunamathela futhi inciphise ukuwohloka kwezinamathelisi zamathayili, ithuthukise ukusebenza namandla ebhondi odaka olusekelwe kusimende, futhi ithuthukise i-rheology nokuzinza kopende nama-coatings.

Kafushane, i-HPMC cellulose ethers idlala indima ebalulekile ekuthuthukiseni ukugcinwa kwamanzi ezintweni zokwakha nezinye izinhlelo zokusebenza eziningi. Isakhiwo sayo esiyingqayizivele samangqamuzana nezici zokuncibilika kwamanzi kuyenza ibe isithasiselo esisebenzayo sokugcina amanzi, iletha izinzuzo eziningi ekusebenzeni komkhiqizo wokugcina.
