Maitiro Ekuvandudza Kuchengeta kwemvura kweHydroxyPropropyl methylcellose?

1. Wedzera iyo degree rekutsiva
Iyo degree rekutsiva kwehydroxypruppropyl uye mapoka mapoka eHpcinobata zvakananga kudzokorora kwemvura kwayo. Dhigirii repamusoro rekutsiva rinozosimudzira kugona kwayo kwemamorekuru emamolekyudhi uye kuvandudza kuchengetwa kwemvura. Naizvozvo, panguva yekugadzira maitiro, chiyero chekutsiva che hydroxyprupyl uye mapoka mapoka anogona kuwedzerwa nenzira kwayo kuti gadzira HPMC ive neyako yekuchengetedza mvura.

2. Ongorora iyo molecular uremu hweHPMC
Iyo smecular uremu hweHPMC ichakanganisa visikopa uye kuchengetwa kwemvura kuchengetedza kwayo mhinduro kwayo. Kazhinji, HPMC ine yakakura molecular uremu inogona kuumba imwe mhinduro yeViscous, nokudaro ichivandudza huwandu hwekuchengetwa kwemvura. Naizvozvo, iyo degree rePolymerization yeHPMC inogona kudzorwa kuti ipe iyo yakakodzera molecular uremu hwekuita iyo yakakodzera mvura yekuchengetedza mvura.

3. Gadzirisa iyo viscosity yeHPMC
Iyo viscosity yekimacell®hpmc ine yakakosha pesvedzero pane yekuchengetedza mvura kuita. Yakakwira-viscosity HPMC inogona kuumba firimu rakasimba remvura rakasimba pamusoro peiyo substrate, kuderedza kubuda kwemvura, uye nekudaro kugadzirisa mvura yekuchengetwa kwemvura. Mukushandiswa kwezvinhu zvekuvaka (senge motty uye putty poda), yepakati-yakakwira viscosity hpmc inowanzo sarudzirwa kuti uwane kudzokorora kwemvura.

4. Ongorora saizi yehukuru hweHPMC
Iyo saizi yehukuru hweHPMC inokanganisa chiyero chayo yekunyungudika uye kuchengetwa kwemvura. Finer HPMC Powder inodonha zvakanyanya mumvura, nekukurumidza inoumba yunifomu mhinduro yekodhi, uye inovandudza kudzokorora kwemvura. Naizvozvo, muitiro wekugadzira, ultrafine tekinoroji inogona kushandiswa kugadzira HPMC ine size diki yechikuru, nekudaro ichisimudzira mvura yekuchengetedza mvura.

5. Dzora chiyero chekunyungudika cheHPMC
Iyo yekunyorovesa chiyero cheHPMC inokanganisa kuparadzaniswa kwayo uye kusarudzika kwemafirimu mukushandisa. Kana HPMC ichipinda nekukurumidza, inogona kukonzera kuwedzera kwemvura kwemvura, nekudaro kuderedza kudzokorora kwemvura. Naizvozvo, dhigirii rekutsvaga reHPMC inogona kugadziriswa kana tekinoroji yekuburitswa inogona kuiswa kuti iite kuti iite mwero waro mumvura zvine mwero, nokudaro uchivandudza kuchinjika kwemvura.

6. Wedzera iyo inopisa yekupisa tembiricha yeHPMC
HPMC ine etermal gelation zvivakwa. Kana tembiricha ichidarika imwe kukosha, ichaumba gel uye kusunungura imwe mvura. Naizvozvo, kuwedzera iyo yekupisa yeHPMC (kureva kuti, tembiricha iyo HPMC inotanga kuGel) inogona kuchengetedza iyo yakanaka yekuchengetwa kwemvura pasi pemamiriro ekunze epamhepo. Kazhinji, tembiricha yemhepo yekupisa yeHPMC inogona kuwedzerwa nekugadzirisa iyo degree rekutsiva uye smecular uremu hweHPMC.

7. Kuwedzeredza neimwe polymer mvura inochengetedza vamiririri
HPMC inogona kuumbwa nedzimwe zvinhu zvekushandisa polymer (senge polyvinyl doro peva, xanthan gamu, guar gum, etc.) kusimudzira kuchengetedza kwemvura. Semuenzaniso, mudhaka uye putty poda, imwe huwandu hwenzvimbo dzinotenderera latex poda (RDP)

8. Kuvandudza Kupararira kweHPMC
HPMC iri nyore kuunganidzira kana ichishandiswa, ichikanganisa kusagadzikana kwaro, nekudaro kuderedza kudzokorora kwemvura. Naizvozvo, nzira dzekurapa dzakarapwa (dzakadai dzekuwedzera hushoma hweloranic saltts

9. Kusarudza yakakodzera HPMC modhi
Mhando dzakasiyana dzeHPMC ine akasiyana mvura yekuchengetwa kwemvura. Mune akasiyana nzvimbo yekushandisa sevhisi yekuvaka, majasi, nemishonga, iyo yakakodzera HPMC muenzaniso inofanirwa kusarudzwa. Semuenzaniso, mukuvaka motoro, hombe-viscosity hpmc inowanzo sarudzirwa, nepo mumapiritsi emishonga, HPMC ine Zvirinani Solubility Kubata kunoda kusimbiswa kwekusunungurwa kwezvinodhaka kuburitswa kwezvinodhaka.

10. Ongorora nzvimbo yekushandisa yeHPMC
Iyo yekuchengetwa kwemvura performance yekimacell®hpmc inokanganiswawo nezvakakomberedza zvinhu zvakadai sekutyisa, humidity, uye rukudzo. Semuenzaniso, mune yakakwirira-tembiricha nzvimbo, huwandu hweHPMC yakawedzerwa kana kushandiswa kwemhando yepamusoro-viscosity yemhando inogona kuwanda zvakaringana kuchengetedza kuchengetedza kwemvura. Panguva imwecheteyo, kudzora iyo yemvura-simende yezvinhu nenzira yemukati mufomula (yakadai sekuwedzera huwandu hwe gypsum kana kubhururuka ash) inogona zvakare kuvandudza kuchengetwa kwemvura kweHPMC.

Kuvandudza kuchengetwa kwemvura kwehydroxyprupyl methylcellose (HPMC)inoda kuti ugadzirire kubva pane zvakawanda zvikamu senge molecular chimiro, zvivakwa zvemuviri, uye mafomu ekushandisa. Nekugadzirisa paramita semagadhi rekutsiva, mamorekuru, viscosity, kusanganisa nzvimbo dzekushandisa uye mafomu ekuratidzira HPMC inogona kuvandudzwa zvakabudirira kuita zvinodiwa neminda dzakasiyana.
