HydroxyPropyl methylcellose (HPMC) ipolmer yakawedzera kushandiswa mukuvaka, mushonga, chikafu uye mamwe minda. Nekuda kwekuchengetwa kwaro kwemvura kwakanakisa, inopa basa rakakosha mumutumbi wetsiva, porofu hupfu, hukudzo uye gadziriso yemishonga. Kuchengetwa kwemvura kweHPMC kunokanganiswa nezvinhu zvakawanda, kusanganisira zvayo zvinongedzo, degree rekutsiva, viscosity, kuwanda kwemari, kusimuka kweiyo substrate uye yekufananidza system.
1. Shandura manyorerwe emanyoreri uye degree rekutsiva
HPMC inoenderana neCellulose Skeleton Chimiro uye Nzira (-Och₃) uye hydroxypriropopopopopoxy (-Och₂chichch₃) Srips, uye danho raro rinotsiva rinoita basa rinokosha mukuchengetwa kwemvura. Kuvapo kwevanopfuura kunowedzera iyo hydrophilicity yeHPMC, nepo ichikanganisawo yayo solubility uye firimu-inoumba zvivakwa. Kazhinji, iyo yakakwira mwero we hydroxyprupropyl substitution, iyo yakasimba iyo hydrophilikuita uye kuchengetwa kwemvura kweHPMC. Iyo nzira yakakwira inobatsira kuvandudza salubility, zvichiita kuti zvive nyore kukiya mumvura uye kudzikisira chiyero chemvura yekubuda kwemvura.
2. Mhedzisiro yeViscosity
Iyo viscosity yeHPMC isakoshesa paramende yekuyera zvivakwa zvetsiva zvemhinduro yayo, kazhinji inotaridzirwa seyekuvona kwe2% mhinduro (MPA · omiti). Mhinduro yacho yakaumbwa neyekumusoro-viscosity HPMC inowedzera uye inogona kuumba yakawanda yemvura yemvura yemvura pamusoro pezvinyorwa, ichinonoka kubuda kwemvura uye nekuvandudza mvura yekuchengetwa kwemvura. Iyo yakaderera-vcosity HPMC Solution ine yakasimba fluidity uye yakakodzera kune nzvimbo dzekushandisa dzinoda kukurumidza kusunungurwa kwemvura. Naizvozvo, muminda yakadai sekuvaka motsi, yakakwirira-viscosity hpmc inoenderana nekuvandudza kuchengetwa kwemvura, nepo low-viscosity HPMC yakakodzera mamiriro ekushandisa anoda kukurumidza kuoma.
3. Mhedzisiro yekuwedzera huwandu
Iko kudzokorora kwemvura kweHPMC kunowedzera nekuwedzera kwekuwedzera kwehuwandu, asi zvakanyanya kunaka. Iyo yakakodzera huwandu hweHPMC inogona kuumba iyo yakagadziriswa hydration firimu mudhaka kana kuunganidza system, kuderedza kukurumidza kurasikirwa kwemvura, uye kuvandudza kushanduka kwekuvaka. Nekudaro, kunyanyisa kushandisa kunogona kutungamira pakukosheswa kwekuona uye kukanganisa maitiro ekuvaka, sekudzora iyo fluidity yemutya uye nekuwedzera nguva yekugara. Naizvozvo, mune zvinoshanda zvinoshandiswa, huwandu hweHPMC hunoda kuve hwakanangana nekufungidzirwa kuti uwane iyo yakanakisa mvura yekuchengeta mvura.
4. Mhedzisiro yeAmberient tembiricha
Tembiricha ine kukosha kwakakosha pakuchengeta kwemvura yeHPMC. Pasi pokupisa zvakanyanya, mvura inoparidza nekukurumidza, uye mvura iri mudhaka kana pendi yakarasika nyore nyore, zvichikonzera kuderera kwekushanda kwekuvaka. HpMC ine zvimwe zvimwe zvigadzirwa zveGel. Kana ichinge ichipfuura tembiricha yayo denderedzwa, ichava nemvura, ichikanganisa mamiriro ekuchengeta mvura. Naizvozvo, munzvimbo dzinopisa kana dzakaoma, zvinodikanwa kusarudza mhando dzakakodzera HPMC uye zvakafanira kuwedzera mari yayo yekuwedzera kwayo yekuchengetedza mvura. Uye zvakare, matanho akadai seyekuvhara uye kupapa kwemvura kunogona kutorwa kuti uderedze kurasikirwa kwemvura.
5. Mvura inotora mwero wekujekesa
Substrate akasiyana ane akasiyana emvura ekunyora masangano, ayo achakanganisawo mvura yekuchengetwa kwemvura yeHPMC. Subsrates neakakwira mvura yekunyora, senge zvidhinha, mabhodhi eGypsum, etc. Mune ino kesi, kushandiswa kwekakwirira-viscosity, yakakwira-kutsiva HPMC inogona kuumba iyo firimu remvura rinogara rakawanda-rekuchengetedza pamusoro pekuderedza kurasikirwa kwemvura. Uye zvakare, kugadzirisa kwakakodzera kune formula, sekuwedzera vamiriri vemvura kana kuderedza mwero wekunyora kwemvura kweiyo substrate, inogona zvakare kuvandudza kuwanda kwemvura yekuchengetedza mvura.
6. Simba reiyo nzira yekufananidza
HPMC inowanzo shanda pamwe chete nezvimwe zvinhu mudhaka, putty kana yekuvhara masisitimu, uye kuchengetwa kwemvura kuchikanganiswa nekuumbwa kwese. Semuenzaniso, chikamu cheiyo simende, lime, hydrate gypsum uye zvimwe zvinhu zvekumisikidza musicum Iko kushandiswa kweAdmiture akadai sekushomeka kwemhepo yekushambadzira vamiririri, manhau, uye machira anozochinjawo mamiriro eHPMC, nekudaro achichinja mari yekuchengetedza mvura. Naizvozvo, kana uchironga kuumbwa, zvinodikanwa kuti ufunge nezvayo yekudyidzana pakati peHPMC uye zvimwe zvinongedzo kuti uwedzere kudzokorora kwemvura yekupedzisira.
Kuchengetwa kwemvura kweHPMC kunokanganiswa nezvinhu zvakawanda, kusanganisira molecular chimiro, degree rekutsiva, viscosity, tembiricha, tembiricha yemvura, yemvura yekunyora, uye nzira yekuumbwa. Mune zvakanyatso mayoreti, zvakakodzera kusarudza iyo yakakodzera HPMC akasiyana-siyana uye kuwedzera huwandu hweshanduro dzakasiyana dzekushandisa uye zvinhu zvekushandisa zvakanakira kudzokorora kwemvura. Uye zvakare, kugadzirisa fomula uye maitiro musanganiswa nemamiriro ekuvaka kunogona zvakare kuwedzeredza kudzokorora kwemvura kuita uye kugadzirisa hunhu uye kushandisa mhedzisiro yechigadzirwa chekupedzisira.
