Naturalmer Polymer Hydroxypropyl methylcellose yeiyo cement based plaster

HydroxyPropyl methylcellose (HPMC) inzvimbo yakasikwa yakashandiswa zvakanyanya mune yekuvaka indasitiri seyakagadzirwa-yakavakirwa plaster. Inogona kushandiswa seyekuchengetwa kwemvura mumiririri, thickener, uye inosungirwa kuti uvandudze mashandiro e-coment-based plasters.

HPMC ndeye semi-synthetic, mvura-yakadzika-mvura polymer yakagadzirwa kubva ku cellulose. Iyo inotorwa kubva kune yakasikwa cellulose kuburikidza nenzira yemakemikari inosanganisira kuwedzera kwehydroxyprupropropropropropropropropropropropropropropropropropropropropropropropropropropyl uye methyl mapoka. Uku kugadziridzwa kunoguma padzimba nedzivandudzika solubility yemvura, kugadzikana kwemvura, uye kurwisa kwemakemikari.

Iko kushandiswa kweHPMC mumasimendi-based Plaster Fomu inopa zvakawanda zvakanakira se:

1. Yakavandudzwa Workability: HPMC zviito senge rheology modifier inovandudza basa rekushanda uye kushandisa zvivakwa zveplaster. Inowedzera kuderera, kubatana, nekupararira kweplaster, kuchibvumira kuti ishandiswe nyore nyore kune substrate.
2. Kugadziridzwa Kwekuchengetwa Kwemvura: HPMC inogona kutora uye kuchengeta huwandu hwakawanda hwemvura, iyo inobatsira kudzivirira iyo plaster kubva pakuomesa nekukurumidza. Ichi chivakwa chinovimbisawo kuti plaster inochengetedza mari yayo uye kushanda kwenguva yakareba, kunyangwe mumamiriro ezvinhu anopisa uye akaoma.
3. Kuwedzera kubatana uye kuderedza: HPMC inoumba firimu rakatenderedza simenti zvikamu, izvo zvinowedzera kubatana kwavo uye kudenha kune substrate. Iyi imba inovimbisa kuti plaster inosara yakasimba uye haina kupaza kana kuparadzanisa kubva kune substrate.
4. Kuderedza kupaza: HPMC inovandudza simba renzvimbo uye kuchinjika kweplaster, kuderedza mukana wekupaza nekuda kwekutsvagisa kana kuwedzera.
5. Kuvandudzwa Kugadzika: HPMC inopa Plaster neakavandudzika kudzivisa kwemvura uye kurwisa kwemakemikari, zvichiita kuti ive yakasimba uye ichiramba kuenderera uye kuchembera.

Pamusoro peiyi mabhenefiti, HPMC iri zvakare inosimba uye zvakatipoteredza zvinowedzera zvinogona kubatsira kuderedza mamiriro ekunze ezvematongerwo enyika. Izvo zvisiri-zvine muchetura, bioderable, uye hazvisunungure zvinhu zvinokuvadza munharaunda.

Kuti ushandise HPMC mumapuranga-yakavakirwa mapuranga, zvinowanzowedzerwa kune yakaoma musanganiswa wejecha nejecha pamberi pekuwedzerwa kwemvura. Iyo Yakakurudzirwa Dosage yeHPMC inosiyana zvichienderana nekunyorera chaiko uye zvivakwa zvaunoda zveplaster. Kazhinji, dosage of 0.2% kusvika 0.5% yeHPMC yakavakirwa pane yakazara uremu hwesimu nejecha zvinokurudzirwa.

HPMC chiitiko chose uye chinoshanda chinokwanisa kugadzirisa zvakanyanya kuita kwekuita kwemasendimita. Yayo yakambovakwa, inogara, uye eco-hushamwari inoita sarudzo inokwezva yevakaroora, vagadziri, uye vanovaka varidzi vanotendeutsa maitiro ekuvaka ekuvaka.
