Ungawuthuthukisa kanjani ukugcinwa kwamanzi kwe-hydroxypropylllyllose methylcellulose?

1
Izinga lokufaka esikhundleni se-hydroxypropyl kanye namaqembu we-methoxyI-HPMCkuthinta ngqo amandla ayo okugcina amanzi. Izinga eliphakeme lokufaka esikhundleni sezinselelo zizothuthukisa amandla ayo angu-Adsorption ama-molecule wamanzi futhi athuthukise umphumela wokugcinwa kwamanzi. Ngakho-ke, ngesikhathi sokukhiqiza, izinga lokufakwa esikhundleni se-hydroxypropyllopyl kanye namaqembu we-methoxy akhuphuke ngokufanelekile ukwenza i-HPMC ibe nokusebenza okungcono kokugcinwa kwamanzi.

2. Lungiselela isisindo se-molecular se-HPMC
Isisindo samangqamuzana se-HPMC sizothinta i-viscosity kanye nomthamo wokugcina amanzi wesisombululo saso. Ngokuvamile, i-HPMC ngesisindo esikhulu samangqamuzana ingakha isixazululo esibonakalayo, ngaleyo ndlela yenza ngcono umthamo wokugcina amanzi. Ngakho-ke, izinga le-polymerization ye-HPMC lingalawulwa ukuze linikeze isisindo esifanelekile sokuthola umphumela ofanele wokugcina amanzi.

3. Lungisa i-viscosity ye-HPMC
I-Viscollity yeKimacell®HPMC inethonya elibalulekile ekusebenzeni kokugcinwa kwamanzi. I-High-Viscutity HPMC ingakha ifilimu enamandla yokugcina amanzi ebusweni be-substrate, ukunciphisa ukuhwamuka kwamanzi, futhi ngaleyo ndlela kuthuthukiswe amandla okugcina amanzi. Ekusetshenzisweni kwezinto zokwakha (njengodaka no-putty powder), i-viscosity ephakathi nendawo ephezulu ye-HPMC evame ikhethwe ukuthola ukusebenza okungcono kokugcinwa kwamanzi.

4. Lungiselela usayizi wezinhlayiyana we-HPMC
Ubukhulu bezinhlayiyana ze-HPMC buthinta izinga lokuchithwa kwalo kanye nomthamo wokugcina amanzi. I-Fener HPMC Powder inciphisa ngokulinganayo emanzini, ngokushesha yakha isixazululo se-colloidal eyunifomu, futhi ithuthukisa ukusebenza kokugcinwa kwamanzi. Ngakho-ke, kwinqubo yokukhiqiza, ubuchwepheshe bokugaya kwe-Ultrafine bungasetshenziswa ukwenza i-HPMC ibe nosayizi omncane wezinhlayiyana, ngaleyo ndlela ithuthukise nomthamo wokugcina amanzi.

I-5. Lawula izinga lokuchithwa kwe-HPMC
Izinga lokuchithwa kwe-HPMC lithinta ukungafani kwalo kanye nekhono elenza ifilimu kuhlelo lokusebenza. Uma i-HPMC inciphisa ngokushesha okukhulu, kungadala ukuhwamuka okusheshayo kwamanzi, ngaleyo ndlela kunciphise ukusebenza kokugcinwa kwamanzi. Ngakho-ke, izinga lokuthethelwa kwe-HPMC lingashintshwa noma likhishwe kancane ngokweqiniso lenze izinga lokuchithwa kwalo emanzini alinganiselwe, ngaleyo ndlela athuthukise umphumela wokugcinwa kwamanzi.

6. Khulisa izinga lokushisa le-gelation ye-HPMC
I-HPMC inezakhiwo ezishisayo ze-gelaeties. Lapho amazinga okushisa edlula inani elithile, uzokwakha ijeli bese ukhulula amanzi. Ngakho-ke, ukwandisa izinga lokushisa le-gelalotion ye-HPMC (okusho ukuthi, izinga lokushisa lapho i-HPMC iqala khona i-gel) ingagcina amandla ayo okugcina amanzi angaphansi kwendawo yokushisa kwamanzi. Ngokuvamile, izinga lokushisa elishisayo le-gelation ye-HPMC lingandiswa ngokulungisa izinga lokufakwa esikhundleni kanye nesisindo se-hpmc.

7. Ukuhlanganisa namanye ama-polymer amanzi agcina ama-ejenti
I-HPMC ingahlanganiswa nezinye izinto ze-polymer (ezinjenge-polyvinyl alcohol PVA, i-xanthan gum, gum gum, njll.) Ukuthuthukisa umphumela wayo wokugcina amanzi. Isibonelo, ku-pulasimende kanye no-putty powder, inani elithile le-latex tablex ye-latex (RDP) noma i-ruble powder ingangezwa ukuze ithuthukise impahla ekwakheka ifilimu kanye nomthamo wokugcina amanzi we-HPMC.

8. Ukuthuthukisa ukuhlakazwa kwe-HPMC
I-HPMC kulula ukugibela lapho isetshenziswa, ithinta ukuchithwa kwayo okufanayo, ngaleyo ndlela kunciphise umphumela wokugcinwa kwamanzi. Ngakho-ke, izindlela zokwelashwa ezifanele zokwelashwa (njengokungeza inani elincane kasawoti noma ama-dispersants) lingasetshenziselwa ukwenza ngcono ukungafani kwalo, ukuze i-HPMC incibilike ngokulinganayo emanzini, ngaleyo ndlela yenza ngcono umthamo wawo wokugcina amanzi.

9. Ukukhetha imodeli efanelekile ye-HPMC
Izinhlobo ezahlukahlukene ze-HPMC zinezakhiwo ezihlukile zokugcina amanzi. Emikhakheni ehlukene yohlelo lokusebenza njengezinto zokwakha, ukumboza, nemithi, imodeli efanele ye-HPMC kufanele ikhethwe. Isibonelo, ekwakheni udaka, i-high-vissusity hpmc kuvame ukukhethwa, ngenkathi kumathebulethi wezemithi, i-HPMC enokusebenza okungcono kwe-solubity idinga ukukhethwa ukuze kuqinisekiswe ukuqina kokukhishwa kwezidakamizwa.

10. Lungiselela indawo yesicelo se-HPMC
Ukusebenza kokugcinwa kwamanzi kweKimacell®HPMC kuthintwa futhi yizici zezemvelo ezifana nokushisa, umswakama kanye nezilinganiso ezibonakalayo. Isibonelo, endaweni evumayo yokushisa ephezulu, inani le-HPMC elingeziwe noma ukusetshenziswa kwemodeli ephezulu kakhulu kungakhuphuke ngokufanele ukuze kugcinwe ukugcinwa kwamanzi okuhle. Ngasikhathi sinye, ukulawula isilinganiso samanzi futhi ulungisa ezinye izithako efomula (njengokukhulisa inani le-gypsum noma ngendiza ash) futhi ungathuthukisa ngokungaqondile umphumela we-HPMC.

Ukuthuthukisa ukugcinwa kwamanzi kweI-Hydroxypropyl methylcellulose (HPMC)Kudinga insizakalo kusuka ezicini eziningi ezifana nesakhiwo samangqamuzana, izakhiwo ezibonakalayo, kanye namafomula wesicelo. Ngokulungisa amapharamitha afana ne-degree yokufaka esikhundleni, isisindo se-molecular, i-viscosity, usayizi wezinhlayiyana, kanye nokuhlanganisa izindawo ezisebenzayo zohlelo lokusebenza namafomula, umthamo wokugcina amanzi we-HPMC angathuthukiswa kakhulu ukuze ahlangabezane nezidingo zezinkambu ezahlukahlukene.
