Hydroxypropyl methylcelcelculose (hpmc, hpmcroxypropyl Methylcelcelse) I-Polymer Polymer ye-Polymer esetyenziswa ngamanzi asetyenziswa kakhulu kwimveliso yokwakha, ngakumbi kwi-pobty powder, iingubo kunye nezinye izinto. I-HPMC ayinayo kuphela iipropathi ezintle zeRheeology kuphela, ukugcinwa kwamanzi, kunye neepropathi ezinkulu, kodwa kunokuphucula ukungasebenzi kunye nokubiyela komda we-poty powder. Kwindlela yoyilo lwefom ye-Stoty, isixa esifanelekileyo se-HPMC sinefuthe elibalulekileyo kumgangatho, ukusebenza kunye noqoqosho lwemveliso.
1. Indima kunye nomsebenzi we-HPMC
Njengesitshixo se-isty powder, i-HPMC inemisebenzi ephambili:
Isiphumo sokuqaqamba: I-HPMC inokwandisa i-viscofity yomgubo wokubeka kwaye iphucule ingqele yakhe. Ngokuhlengahlengisa isixa se-HPMC songezwe, ukungqinelana komgubo ongezantsi kunye nobungqingqwa ngexesha lokwakha kunokulawulwa ukuqinisekisa ukuba i-poty inamathele kudonga.
Ukugcinwa kwamanzi: i-HPMC inokuphucula umsebenzi wokugcina amanzi, kwandise ixesha lokuvula lomgubo, kwaye uphephe ukomisa ngaphambi kwexesha kunye nokuqhekeka kwezinto ngexesha lenkqubo yokwakha. Oku kubaluleke kakhulu xa ufaka isicelo kwiindawo ezinkulu, ngakumbi ngendlela eshushu, eyomileyo.
Ukuphucula i-adhesion: Ukusetyenziswa kwe-HPMC kwi-popler enokunyusa ububi phakathi kwayo kunye nezinto ezisisiseko (njengodonga lweqhinga (iBhodi yeGypsim, njl.njl.
Ukuphucula ukugqitywa komgangatho: Ngenxa yesiphumo esihle se-HPMC, i-pople powder inokugcwalisa ngcono ubukhulu obuncinci eludongeni, esenza ukuba umhlaba ugudile kwaye uthambile, kunye nokuphucula i-aesthetics.
2. Isiphumo se-HPMC Dosage kwintsebenzo yomgubo we-putty
Ukusebenza ngokwakha
Isixa se-HPMC kwi-posty powder ichaphazela ukusebenza kwayo ngokwakhiwa. Isixa esifanelekileyo se-HPMC sinokuphucula i-fluidsity kwaye ivule umgubo we-poty powder. Uluhlu lwedosi oqhelekileyo yi-0.3% ~ 1.0% (ibalwe ngokusekwe kubunzima be-poty powder). Xa idosi ye-HPMC iphantsi, umgubo ongezantsi unobungqingqwa kwaye unokunamathela kwaye atywinwe ngexesha lokwakha, enze ukuba kube nzima ukulawula ubukhulu; Ngelixa idosi ye-HPMC egqithisileyo inokubangela ukuba i-powty powder ibe mncinci kakhulu kwaye kunzima ukuyifaka isicelo ngexesha lokwakha, ukwandisa ubukhulu bomsebenzi.
umgangatho womphezulu
Iziphumo ezihlekisayo ze-HPMC zenza ukuba i-powty powder ineendlela ezingcono zokwakha. Ingakumbi ngexesha lenkqubo yokwakha, umgubo ongezantsi unokuwathobela ngokungqameko kudonga kwaye unciphise i-phenomenon yomgubo. Imali ephakathi ye-HPMC inokulawula ngempumelelo isantya sowoyikisayo somgubo wokubeka kwaye siphephe iziphene zomphezulu ezibangelwa kukuqhekeka kowo. I-dosage ye-HPMC ye-HPMC inokubangela umgubo wokubekwa ukuba ume ngokukhawuleza kwaye wenze imifula; Ngelixa idosi ephezulu kakhulu inokubangela ukuba umphezulu ogudileyo kakhulu, okhokelela ngokulula ekunciphiseni komthendeleko kunye nokuhamba.
Ubunzima kunye namandla
Isixa se-HPMC sikwanayo nefuthe elithile kubunzima kunye namandla omgubo we-poty powder. Ngokubanzi, xa isixa se-HPMC siphantsi, ubunzima kunye namandla e-poty powder ihlwempu, kwaye ukhulula okanye ukrokrela okanye ukuthuthuzela kunokuza kwiiyure ezimbalwa emva kokwakha; Ngokufanelekileyo ukwandisa isixa se-HPMC sinokuphucula ukunganyangeki kwamandla kunye namandla e-poty powder. Ukomelela, ukunika ukuqina okungcono emva kokukhanya.
Ukugcinwa kwamanzi kunye nesantya esomileyo
Inqaku elahlukileyo le-HPMC kukuba linokuphucula kakhulu ukugcinwa kwamanzi kumgubo we-poty powty, obaluleke kakhulu ukusebenza ngexesha lenkqubo yokwakha. Xa idosi iphantsi, umgubo ongezantsi uya kuphulukana namanzi ngokukhawuleza, kwaye ukomisa ngokukhawuleza kuya kukhokelela kwiingxaki ezinje ngemiguba yomgubo kwaye aqhekeka ngexesha lokwakha. Isixa esifanelekileyo se-HPMC sinokugcina umgubo obekwe eludongeni ngokufuma ngokwaneleyo, ukuqinisekisa ukuba inexesha elaneleyo lokuthambisa kwaye linciphise. Xa idosi iphakame kakhulu, ipowuni ye-setty isenokuba yi-viscous kakhulu, ikhokelela ekumonisweni okungalinganiyo emva kokwakha emva kokwakha kwaye kuchaphazele ukugungqa komaleko otyhafileyo.
Uqoqosho
Nangona i-HPMC inezinto ezininzi ezibalaseleyo, njengesongezo ezisebenzayo, iindleko zayo ziphezulu. Nangona ukusetyenziswa kakhulu kwe-HPMC kunokuphucula ukusebenza kwe-powty powder, iya kukwandisa iindleko zemveliso. Ke ngoko, kwinkqubo yemveliso yomgubo, ukusetyenziswa kwe-HPMC kufuneka kulawulwa ngokufanelekileyo ngokweemfuno ezithile kunye neemfuno zoqoqosho ukufezekisa ibhalansi phakathi kokusebenza kunye neendleko.
3. Umahluko kwivolumu yeentlobo ezahlukeneyo ze-HPMC
I-HPMC yahlulahlulwe yaziintlobo ezahlukeneyo ngokweendlela ezahlukeneyo zokulungiswa, ezinje nge-HPMC enenqanaba eliphantsi lokufaka endaweni kunye nenqanaba eliphezulu. Iziphumo zokusetyenziswa kwayo kwi-patty powder zinokwahluka. I-HPMC enenqanaba eliphantsi lokufakelwa endaweni yexesha lokuvula kunye nexesha elide lokuvula, kwaye ilungele umgubo ofuna ixesha ofuna ixesha elide lokusebenza; Ngelixa i-HPMC enenqanaba eliphezulu lokufaka endaweni yokuphucula ulwelo kunye nolwelo lwe-podty powder ngexesha elifutshane. Ukwakha. Ngokweentlobo ezahlukeneyo ze-HPMC, uluhlu lwedosi ziya kulungiswa. Ngokubanzi, umthamo we-HPMC enasezantsi iphezulu kakhulu.
Isixa se-HPMC esisetyenziswa kwi-popler sinefuthe ngqo kwintsebenzo yomgubo we-poty powder. Umthamo ofanelekileyo unokuphucula ukusebenza kwe-powty powder, ukuphucula umgangatho womhlaba, ukuphucula ukugcinwa kwamanzi, ukuphucula ubumbethe kwaye unyuse amandla. Nangona kunjalo, ukusebenzisa kakhulu okanye kuncinci kunokuba kuchaphazela kakubi ukusebenza komgubo obekiweyo. Ukuphamba, idosi efanelekileyo ye-HPMC kufuneka ithathelwe ingqalelo ngokusekwe kwiimfuno ezithile zesicelo zomgubo, indawo yokwakha, iindleko zoqoqosho kunye nezinye izinto. Ngokwenza isixa se-HPMC, ukusebenza kunye nomgangatho we-poty powder inokuphuculwa ngokufanelekileyo ukufezekisa iimfuno zemarike kunye nabasebenzisi.
