Hunhu hweHPMC mune yakaoma-yakasanganiswa moter

1. Hunhu hweHPMC mune yakajairika motsi

HPMC inonyanya kushandiswa seyedzorwe uye yekuchengetwa kwemvura mumirimo mukugadzika kwesimendi. Muzvikamu zvekongiri uye mongwe, inogona kuvandudza zvevasangano uye kuderera kwehuremu, kusimbisa simba rekushongedza, kudzora simenti kushanda nguva, uye kuvandudza kutanga kwekutanga uye kusimba kwekutama. Nekuti ibasa rekuchengetedza mvura, inogona kuderedza kurasikirwa kwemvura pane imwe kongiri pamusoro, dzivisa marara kumucheto, uye nekuvandudza kuderera uye kuita zvekuvaka. Kunyanya mukuvaka, nguva yekugara inogona kuwedzerwa uye yakagadziriswa. Nekuwedzera kwezvinhu zveHPMC, nguva yekugara yevhu ichaendeswa zvakanyanya; Kuvandudza iyo michina uye kusimuka, yakakodzera pakuvaka kuvaka; Kuvandudza kushanda kwekuvaka uye kubatsirwa nzvimbo yekuvaka inochengetedza kubva kumamiriro ekunze emvura inoyevedza mvura.

2. Hunhu hweHPMC mune yakakosha motsi

HPMC ndeyekubudirira kwemvura-inokwanira mumiririri weiyo yakaoma poda poda dhiri, iyo inoderedza chiyero chekubuda ropa uye chinonhuwira cheturusi uye chinovandudza kosi yemutya. Kunyangwe HPMC zvishoma inoderedza simba rinosindimara uye rinomanikidza rwejasi, rinogona kuwedzera zvakanyanya simba resimba uye bond simba remutya. Mukuwedzera, HPMC inogona kunyatsoita basa rekuumbwa kwepurasitiki mumbato uye kuderedza iyo plastiki yekuvhuvhuta indekisi yemota. Kuchengetwa kwemvura kwekuwedzera kwemota kunowedzera nekuwedzera kweHPMC viscossity, uye apo visikoka kupfuura 100000mpa 000, kuchengetwa kwemvura hakuwedzere zvakanyanya. Iyo yakajeka yeHPMC zvakare ine imwe pesvedzero pane iyo mvura yekuchengetera mwero wedhaka. Kana iwo masisitimu ari akanaka, iyo mvura yekuchengetwa kwemvura inovandudzwa. Iyo HPMC yekristle saizi kazhinji inoshandiswa kune simende frin inofanirwa kunge isingasviki mazana masere emicons (80 mesh skrini). Iyo yakakodzera dosage yeHPMC mune yakaoma PoWder Dorar ndeye 1 ‰ ~ 3 ‰.

2.1. Mushure meiyo HPMC muMoturu yakanyungudutswa mumvura, iyo inoshanda uye yunifomu yekugoverwa yezvinyorwa zvekushandiswa mune system inovimbiswa nekuda kweiyo nzvimbo yekuita. Sechiverengero cholloid, hpmc "kuputira" masisitimu akasimba uye anoumba dhizaini pane yayo yekunze. Chikamu cheLubricating firimu inoita kuti iyo dormy system yakagadzikana, uye zvakare inovandudza iyo fluidity yemutya panguva yekusanganisa maitiro uye kusimba kwekuvaka.

2.2. Nekuda kweizvozvo mholocular chimiro, mhinduro yeHPMC inoita kuti mvura iri nyore kurasikirwa, uye inoburitsa zvishoma nezvishoma kwenguva yakareba, inoburitsa dhayeti nekuchengetwa kwakanaka kwemvura uye nekuchengetwa kwemvura. Inogona kudzivirira mvura kubva mukuyerera nekukurumidza kubva mudura pachigadziko, zvekuti mvura yakachengetwa inogara pamusoro pezvinyorwa zvitsva, izvo zvinogona kusimudzira hydration yeiyo simende uye kugadzirisa simba rekupedzisira. Kunyanya kana iyo interface ichisangana neComent Motar, Plaster, uye inonamatira inorasikirwa nemvura, ichi chikamu hachina simba uye chero pasina simba. Kunyanya kutaura, nzvimbo dzekusangana nezvinhu izvi zvese zvinoshambadzira, zvichikonzerwa neyakawoneka pasi, kuganhurisa tiles simbetera uye ceramic matairi kana plaster uye madziro simba rekubatanidza pakati pezvivakwa zvinodzikira.

Mukugadzirira kwerufu, kuchengetwa kwemvura kweHPMC kwakanyanya kuita. Zvakaratidzwa kuti kuchengetwa kwemvura kunogona kuve kwakakwirira se 95%. Kuwedzera kweiyo molecular uremu hweHPMC uye kuwedzera muhuwandu hwesimende kuchavandudza kuchengetedza kwemvura uye kusimbisa simba remutya.

Muenzaniso: Sezvo zvinoshatisa zvinoshatisa zvinofanirwa kuve nesimba rakakwirira simba pakati nepakati nepakati uye mataira, chinonamatira chinokanganiswa neyemvura kubva kune maviri manhamba; substrate (rusvingo) kumusoro uye mataira. Kunyanya kune matairi, hunhu hwakasiyana-siyana, vamwe vane pores hombe, uye mataira ane mvura yakakwira yemvura, inoparadza basa rekubatanidza. Iyo yemvura-yekuchengetedza mumiririri inonyanya kukosha, uye kuwedzera HPMC inogona kusangana ichi chinodiwa.

2.3. HPMC yakagadzikana kuAcid naAlkali, uye yavo yemvura mhinduro yakagadzikana kwazvo mune huwandu hwePH = 2 ~ 12. Caustic soda uye lime mvura ine zvishoma kushanda pane zvayo kuita, asi Alkali inogona kukurumidza kukurumidza kupaza uye zvishoma kuwedzera viscosity yayo.

2.4. Kuita kwekuvaka kweiyo motoro kwakawedzerwa neHPMC kwave kwakagadziriswa zvakanyanya. Iyo motwe inoita kunge "oiri", iyo inogona kuita kuti madziro azere, gadzira nzvimbo kana zvidhinha uye zvidhina uye zvinogona kuwedzera nguva yekuvhiya, yakakodzera kuvaka kwakakura.

2,5. HPMC ndeye isiri-ionic uye isiri-polymeric Electrolyte, iyo yakagadzikana pakupedzisira mhinduro nesimbi uye emagetsi emagetsi, uye inogona kuwedzerwa pakuvaka kwenguva yakareba kuti ive yakafanira kugadzikana kunovandudzwa.
