HydroxyPropyl methylcellose (HPMC) ndeyekuti inoshandiswa zvakanyanya muumbi mongororo uye ine mabasa akasiyana siyana ayo anogadzirisa kuita uye kushanda kwemutya. Zvemukati zvinosanganisira chimiro chemakemikari cheHPMC, maitiro ayo ekudyidzana mune mertar matrix, uye nekukanganisika kwacho pane zvivakwa zvevhu nyowani uye dzakaomeswa mota.
Mota chinhu chakakosha mukuvaka chinoita senge binder yemasonry zvikamu, kupa kubatana uye kugadzikana kuchimiro. Iko kuita kweiyo drar inokanganisa zvakanyanya kutendeka uye kuregererwa kwechivako, saka zvinopesana zvinodikanwa kuti ugadzirise zvivakwa zvaro. Pakati peizvi zvinodhaka, hydroxyprusyl methylcellose (HPMC) inobuda seyakaverengeka zvinyoronyoro zvinopa zvakanakira mongororo yemota. Chinyorwa ichi chinosimbisa chinzvimbo cheHPMC mune mongororo yemotokari, chinosimbisa maitiro ayo pane zvakasiyana-siyana pazvinhu zvakasiyana, uye zvinotarisa maitiro epasi pekudzora mashandiro ayo.
1.comemical chimiro uye zvivakwa zveHPMC
Hydroxyprupyl methylcellulose ndeyavo cellulose ether mhuri uye inotorwa kubva ku cellulose kuburikidza nemakemikari kugadzirisa. Kutsiva kwehydroxypropyl uye methyl mapoka pane cellulose backbone inopa HPMC yakasarudzika zvinhu, kusanganisira iyo solubility yemvura, yefirimu-inoumba kugona, uye chiitiko chemafirimu. Dhigirii rekutsiva
2. Mechanism yekuita
HPMC inokanganisa madhiri kuburikidza nemirairo dzakasiyana-siyana, kunyanya nekuda kwekudyidzana kwayo nemvura uye zvigadzirwa zvemvura. Mushure mehydration, HPMC mamorekuru inoumba iyo collive colloid yakakomberedza zvimedu zvemvura, kudzorera kubuda kwemvura uye kusimudzira hydration. Izvi zvinowedzera kuchengetwa kwemvura kwemvura mertar matrix, kuwedzera kushanda uye kuderedza njodzi yekupaza. Mukuwedzera, HPMC inogona zvakare kushandiswa sekunamatira kuti uvandudze kuderedza pakati pehudyu uye nekuvandudza simba rekubatanidza uye kuderedza shiri uye kuderedza shrinkage.
3. Mhedzisiro yekuita kweiyo nyowani nyowani
Mune madhiri matsva, HPMC inopa zvivakwa zvinodikanwa zvinodikanwa, kusanganisira yakagadziridzwa kusarudzika, kuderedza uye kusununguka kwekushandisa. Nekugadziridza maitiro eReological yerudzi, HPMC inovandudza kushanda uye kushungurudzika, kubvumira kuiswa kwakaringana uye kuenzanisa. Mukuwedzera, HPMC inoderedza tsika yekuzvitsaurira uye kubuda ropa, ichivimbisa kufanana uye homogeneity yemusanganiswa wechifuru.
4. Mhedzisiro yekuita kwekuomarara kwakaomeswa
Mumauto akaomeswa, kuvapo kweHPMC kunobatsira kuvandudza kusimba, simba uye kuramba kune zvinhu zvakatipoteredza. Nekutsvagisa mvura yekuparadzira mvura uye simende hydration, hpmc inosimudzira kukura kweiyo micrenture yercentige, inoderedza kubvumirana uye kunovandudza manhamba. Mukuwedzera, HPMC inoderedza shrinkage uye kupaza panguva yekuomesa uye kuporesa, nekuvandudza kudzikisira kwakadzikama uye kuderedza zvinodiwa.
5. Inoshanda kufunga nezvekushandisa HPMC
Okisheni yekuita yeHPMC muMormarm Compositions inoda kunyatsofungisisa nezvezvinhu zvakasiyana-siyana, kusanganisira dosage, chidimbu chevamwe, uye kuenderana nevamwe vanowedzera. Doisage yakawandisa yeHPMC inogona kutungamira kwenguva yakareba yekuedza uye yekutanga simba kuderedzwa, saka inoda kusarudzwa nekuchenjera maererano nezvinodiwa chaizvo. Chikamu chekugovera chinobata zvakare kupararira uye kushanda kweHPMC mumotokari, ine zvidimbu zvidimbu zvinoratidza zvakakwirira zvekuchengetwa kwemvura. Uye zvakare, kuenzanisa kwekuedza pamwe nezvimwe zvinyoreso zvakakosha kuti udzivise zvakashata zvekusangana uye kuona kuti synergistic mhedzisiro.
HydroxyPropyl methylcellose (HPMC) inokosha inowedzera muumbi mongororo uye inopa zvakati wandei mukuvandudza kuita uye kushanda. Nekukwanisa kwaro kusimudzira kuchengetwa kwemvura, kujaira uye kusimba, HPMC inoita basa rinokosha mukutsvagisa kuita kwemaviri mutsva uye akaomeswa motsi. Nekunzwisisa maitiro ehukadzi eHPMC uye achifunga nezvekudzivirira maitiro kuburikidza nekufungisisa kwekushandiswa kwayo, vaongorori uye varapi vanogona kunyatsoongorora kugona kufambisira mberi tekinoroji uye kuzadzisa zvido zvechishandiridzo zvekuvaka.
