I-HPMC (HYDROXYPROPYL Methylcellulose) Ingabe umfashini obalulekile ovame ukusetshenziswa ezintweni zokwakha ezifana ne-putty powder, ukumboza, ukunamathela, njll. Inemisebenzi eminingi efana nokuqina kwamanzi, kanye nokwenza umsebenzi wokwakha okuthuthukile. Ekukhiqizeni i-putty powder, ukungezwa kwe-HPMC akunakuthuthukisa ukugcinwa kwamanzi kuphela komkhiqizo, kepha futhi kwandise ngempumelelo nesikhathi sayo sokwakha, vimbela i-putty ekusomisweni ngokushesha okukhulu ngesikhathi sokwakha, futhi kuthinte umphumela wokwakha.
1. Khetha imodeli ye-HPMC efanele
Ukusebenza kwe-HPMC kuhlobene kakhulu nesisindo sayo se-molecular, i-hydroxypropyls esikhundleni, indawo yokungena kwe-methyl nezinye izinto. Ukuze uthuthukise ukugcinwa kwamanzi kwe-putty powder, qala ukhethe imodeli efanelekile ye-HPMC.
I-Vissesity ephezulu ye-HPMC: I-HPMC ngesisindo esiphakeme samangqamuzana ingakha isakhiwo senethiwekhi esinamandla, esiza ukuthuthukisa ukugcinwa kwamanzi kwe-putty powder futhi ivikele ukuguquguquka ngaphambi kwesikhathi kwamanzi. Ngokuvamile, i-HPMC enokubonakala okuphezulu kuzoba nomthelela omuhle kumthamo wokugcinwa kwamanzi.
I-degree efanelekile yokufaka esikhundleni sokufaka esikhundleni I-degree ephakeme ye-hydroxypropyl efakwa esikhundleni sisiza ukuthuthukisa i-hydrophility ye-HPMC, ngaleyo ndlela ethuthukisa ukusebenza kwayo kokugcina amanzi.
Ngokwezidingo ze-putty powder, ukukhetha imodeli ye-HPMC efanele kungathuthukisa kakhulu inani lokugcinwa kwamanzi lomkhiqizo.
2. Khulisa inani le-HPMC elingeziwe
Ukuze uphinde uthuthukise ukugcinwa kwamanzi kwe-putty powder, inani le-HPMC elingeziwe lingakhuphuka ngendlela efanele. Ngokwengeza isilinganiso se-HPMC, ukusatshalaliswa kwayo ku-tutty kungathuthukiswa ngempumelelo futhi nomthamo waso wokugcina amanzi ungathuthukiswa.
Ukwanda kwenani lesengezo kuzoholela ekwandeni kokubonakala kwe-putty powder. Ngakho-ke, kuyadingeka ukuthi kuqinisekiswe ukugcinwa kwamanzi okuhle ngenkathi kugwema ukubonakala ngokweqile kwento yokuthola ukusebenza kokwakha.
3. Idizayini yefomula enengqondo
Ifomula design of putty powder ithinta ngqo ukugcinwa kwamanzi. Ngaphezu kwe-HPMC, ukukhethwa kwezinye izakhi ezisefomula (ezifana nama-filler, anamathela, njll.) Kuzothinta nokugcinwa kwamanzi kwe-Putty Powder.
I-FixPeness kanye nendawo ethize yendawo: usayizi wezinhlayiyana kanye nendawo ethize yeI-filler ku-putty powder izothinta ama-adsorption amanzi. Ama-powders amahle nabasizi abanendawo ephezulu engaphezulu bangadonsa amanzi kangcono futhi banciphise ukulahleka kwamanzi. Ngakho-ke, ukukhethwa okunengqondo kosayizi wezinhlayiyana kwe-filler kuyinto ebalulekile ekwenzeni ngcono ukugcinwa kwamanzi.
Ukukhethwa kwesithasiselo sezithako: Uma i-Putty Powder iqukethe usimende nezinye izithako, ukusabela kwe-hydration ngosimende kungadla amanye amanzi. Ngakho-ke, kuyadingeka ukwandisa ukugcinwa kwamanzi kwe-putty ngokulungisa isilinganiso sikasimende kuya ku-filler.
4. Lawula inqubo yokuxuba
Inqubo yokuxuba nayo inomthelela othile ekugcinweni kwamanzi kwe-putty powder. Ukuxuba okunengqondo kungasiza i-HPMC isabalalisa ngokuphelele futhi ihlanganise ngokulinganayo nezinye izithako zokugwema ukungezwani ekugcinweni kwamanzi okubangelwa ukuxutshwa kwamanzi okubangelwa ukuxutshwa kwamanzi okubangelwa ukuxutshwa kwamanzi okubangelwa ukuxutshwa kwamanzi okubangelwa ukuxubana kwamanzi.
Isikhathi esifanelekile sokuxuba kanye nesivinini: Uma isikhathi sokuxuba sifushane kakhulu, i-HPMC ingahle ingachithwa ngokuphelele, ezothinta ukusebenza kwayo kokugcina amanzi. Uma ijubane lokuxuba liphezulu kakhulu, kungenziwa umoya omningi, othinta ikhwalithi ye-putty powder. Ngakho-ke, ukulawula okunengqondo kwenqubo yokuxuba kuzosiza ukuthuthukisa ukugcinwa kwamanzi okuphelele kwe-putty powder.
5. Lawula umswakama wezemvelo kanye nokushisa kwezemvelo
Ukugcinwa kwamanzi kwe-putty powder akuhlobene kuphela nezinto zokwakha kanye nefomula, kodwa futhi kuhlobene kakhulu nomswakama kanye nokushisa kwendawo yokwakha. Emvelweni enokushisa okuphezulu kanye nomswakama ophansi, umswakama we-putty powder kulula ukuhwamuka, okwenza kome ngokushesha okukhulu futhi kuthinte umphumela wokwakha.
Ngesikhathi senqubo yokwakha, izinga lokushisa elifanele nezimo zomswakama kufanele ligcinwe ngangokunokwenzeka ukuvikela i-putty powder ekulahlekelweni kwamanzi ngokushesha okukhulu. Ukulawulwa okufanele kokushisa okukhona kanye nomswakama kungathuthukisa ngokungaqondile ukugcinwa kwamanzi kwe-putty powder.
6. Faka umenzeli wokugcina amanzi
Ngaphezu kwe-HPMC, amanye ama-ejenti okugcina amanzi nawo angabhekwa ukuthi angezwe ku-Putty Powder, njengama-polymers athile, njll. La ma-ejenti agcinwe amanzi angathuthukisa ukugcinwa kwamanzi, futhi avikele i-Putty ekujuleni nasekuqhekeke ngokushesha okukhulu.
Kodwa-ke, lapho ungeza ama-ejenti okugcina amanzi, kuyadingeka ukunaka ukuhambisana kwawo nge-HPMC ukuqinisekisa ukuthi akukho mbono onzima owenzeka noma kuthinta ukusebenza kokwakhiwa kwe-putty.
7. Sebenzisa ubuchwepheshe bokulawula umswakama
Kwezinye izikhathi ezikhethekile, ubuchwepheshe bokulawula umswakama bungasetshenziswa ukuthuthukisa ukugcinwa kwamanzi kwe-putty powder. Isibonelo, ukusetshenziswa kwama-membranes asuselwa emanzini asuselwa emanzini noma imishini yokunikezwa komswakama kunganciphisa ngokuphumelelayo ukulahleka kwamanzi nge-putty ngesikhathi sokwakha, gcina ukumanzi kwesendlalelo se-tutty, ngaleyo ndlela uthuthukise isikhathi sawo sokwakha kanye nokwenza ngcono ukugcinwa kwamanzi.
Ukugcinwa kwamanzi kwe-putty powder kungathuthukiswa ngempumelelo ngokukhetha uhlobo olufanele lweI-HPMC, ukukhulisa inani lokungezwa, okwenza ifomula, ukuthuthukisa inqubo yokuxuba, ukulawula umswakama kanye nokushisa kwendawo yokwakha, nezinye izinyathelo. Njengengxenye ebalulekile ye-putty powder, ukuthuthukiswa kokugcinwa kwamanzi kwe-HPMC akunakuthuthukisa ukusebenza kwezokwakha kuphela, kepha futhi kuthuthukise ikhwalithi yokugcina yokwakha futhi kunciphise amaphutha nezinkinga ekwakhiweni nasezinkinga. Ngakho-ke, ukuqonda kanye nokuqonda lezi zindlela ukuthuthukisa inani lokugcinwa kwamanzi kubaluleke kakhulu kumabhizinisi akhiqiza futhi asebenzise i-putty powder.
