1. I-solubity kanye nokubonakala kwe-HPMC
Njenge-cellulose ancibilikayo esuselwa e-cellulose, i-HPMC isetshenziswa kabanzi ezintweni zokwakha, ikakhulukazi ku-putty powder, lapho idlala khona indima yokuqina, ukugcinwa kwamanzi, kanye nokwenza ngcono ukusebenza kokwakha. Ngesikhathi senqubo evuthayo ye-putty powder, ijubane lokuvuselela isikhathi kanye nesikhathi isikhathi kungathinta i-solubity nokubona kokugcina kwe-HPMC. Uma ukugqugquzela kukhulu kakhulu noma isikhathi esishukumisayo isikhathi eside kakhulu, i-solubity ye-HPMC ingancipha, ngaleyo ndlela kuthinte umphumela wayo wokuqina nokugcinwa kwamanzi. Kulokhu, ukusebenza kwezokwakha kwe-putty powder kungathinteka, njengokuqhekeka, ukulahleka kwempuphu nezinye izinkinga.
Ngakolunye uhlangothi, ikhwalithi ye-diliunt izothinta nokusebenza kwe-HPMC. Uma izinga lamanzi le-dilount limpofu, liqukethe ukungcola okuningi kakhulu noma linokuqukethwe kukasawoti okuphezulu, kungasabela kabi nge-HPMC, okuholela ekuchitheni okungaphelele kwe-HPMC noma umphumela wokuncishiswa we-gelation, okugcina kuthinta ikhwalithi yokwakha ye-Putty powder.
2. Ukufana kokuvusa
Ukufana kwenqubo evuthayo kubalulekile kwikhwalithi yokugcina ye-putty powder. Uma ukugqugquzela akwanele, i-HPMC nezinye izithako (njenge-gypsum, i-titanium dioxide, i-calcium carbonate, i-calcium carbonate, okungase kubangele ukugxilwa kwe-HPMC kwezinye izindawo ze-putty kanye nendlela ephansi kakhulu, ngaleyo ndlela kuthinta umphumela ophelele kanye nokusebenzisa umphumela. Isibonelo, okuqukethwe okuphezulu kakhulu kwe-HPMC endaweni yendawo kungadala ukuthi i-putty powder ibe nokubona kakhulu, okuthinta ukusakazeka; Ngenkathi okuqukethwe okuphansi kakhulu kwe-HPMC kungadala ukuthi i-putty powder ibe nokunamathela kabi futhi kulula ukuwa ngesikhathi sokwakha.
3. Ithonya lamanzi e-dilution
I-Dilution Water iyinto ebalulekile kwinqubo yokukhiqiza ye-Putty Powder. Ubulukhuni, ph, usawoti oncibilikisiwe, njll. Amanzi azothinta i-solubity nokusebenza kwe-HPMC. Isibonelo, i-calcium kanye ne-magnesium nama-ion emanzini anzima azosabela nge-HPMC ukwakha imvula, kunciphise insocility ye-HPMC, futhi ngaleyo ndlela kuthinte umphumela wokugcina we-Putty Powder. Uma kusetshenziswa amanzi athambile noma amanzi amsulwa, i-HPMC ingadlala indima engcono, ukuze ukwakhiwa nokunamathela kukaPutty Powder kuqinisekisiwe.
4. Ingxenye ye-HPMC
Isilinganiso sokungeza se-HPMC sithinta ngqo ikhwalithi yokugcina ye-Putty powder. Ngesikhathi senqubo yokuxuba nokunciphisa, uma ingxenye ye-HPMC ayifanelekile, noma ngabe ikhulu kakhulu noma incane kakhulu, izothinta ukusebenza kwe-putty powder. Isibonelo, uma i-HPMC ingezwa kakhulu, ukubonakala kwe-putty powder kuzoba phezulu kakhulu, okungaholela ekusetshenzisweni okungalingani; Ngenkathi i-HPMC ingezwa incane kakhulu, kungaholela ekunikezelweni okunganele kwe-Putty Powder bese uwa ngesikhathi sokwakha.
5. Umphumela wokushisa
Izinguquko zokushisa ngesikhathi sokuxuba nokubhulubula nazo zizothinta nekhwalithi nokusebenza kwe-HPMC. Ngaphansi kwezimo zokushisa eziphakeme, i-HPMC ivame ukuncibilikisa kakhulu, kepha lapho izinga lokushisa liphezulu kakhulu, kungasheshisa ukucekelwa phansi kwe-HPMC, ngaleyo ndlela kunciphise ukusebenza kwayo. Ngakolunye uhlangothi, i-solubity ye-HPMC izokwehla ngaphansi kwezimo zokushisa eziphansi, ithinta umphumela wayo wokuqina. Ngakho-ke, ngesikhathi senqubo yokuxuba nokuhlamba, kuyadingeka ukuqinisekisa ukuthi izinga lokushisa kufanelekile ukuqinisekisa ukuthi i-HPMC ingachithwa ngokuphelele futhi isebenze kahle kakhulu.
I-6. Umphumela wokuvuselela imishini ku-HPMC
Indlela nesivinini sokuvuselelwa kwemishini nakho kuyinto edinga ukunakwa. Uma ijubane lokuvuselela lishesha kakhulu, ikakhulukazi eliphakeme elinobudlova elinobudlova, kungadala ukuthi isakhiwo se-HPMC sibhujiswe, sinciphise imisebenzi yaso yokugcina amanzi. Ngaphezu kwalokho, ukushukumisa okukhulu kakhulu kungadala ukuthi amanzi akhiphe ngokushesha okukhulu, okuholele ekuchitheni okungaphelele kwe-HPMC kanye nokuthinta umphumela wokugcina wokusetshenziswa kwe-Putty Powder.
Inqubo evusa amadlingozi ye-putty powder iyathinta ikhwalithi nokusebenza kwe-HPMC. Ukuze uqinisekise ikhwalithi ye-putty powder, kuyadingeka ukulawula ukufana nokushisa okuvusa, khetha i-dilution amanzi afanele, bese wengeza i-HPMC ngokuqinile ngokuya ngesilinganiso. Ngasikhathi sinye, gwema isivinini esishukumisayo eseqile kanye ne-dilorent engafanele yokuqinisekisa ukuthi i-HPMC ingadlala ngokugcwele indima yayo ekukhulekeni, ukugcinwa kwamanzi kanye nokwenza ngcono ukusebenza kokwakha.
