Nhungamidzo:
Gypsum Plaster, zvinyorwa zvekuvaka zvakazara zvinozivikanwa nekunyorwa kwake uye kusununguka kwekushandisa, kwawona kufambira mberi kwakakura mumakore apfuura nekubatanidzwa kweiyo hydroxpremyl methelose (HPMC). HPMC, iyo cellulose ether inobva, inopa huwandu hwezvinhu zvinodikanwa zvinowedzera kuita uye kushanda kwe gypsum plaster formas. Chinyorwa ichi chinopera mubasa reHPMC muGypsum Plaster Series, goverting maitiro ayo emakemikari, hunhu hunoshanda, uye zvinorehwa.
Chemical kuumbwa uye zvivakwa zveHPMC:
HydroxyPropyl methylcellose iri yakashongedzwa kuburikidza nemakemikari kugadziridzwa kwemheremalose, zvichikonzera poluble yemvura ine zvivakwa zvakasiyana. Chemakesi yayo yemakemikari inosanganisira cellucose backbone maketani ane methyl uye hydroxyprupropyl subsituents. Dhigirii rekutsiva HPMC inoratidzira yakanakisa mvura yekuchengetwa kwemvura, kugadzira yakagadzikana colodal mhinduro dzinopa kudzikisira kudzorera uye kuderedza muGypsum Plaster.
Mabasa eHPMC muGypsum Plaster:
Kuchengetwa kwemvura: HPMC zviito se hydrophilic polymer, kugadzira firimu rekudzivirira kutenderera neGypsum zvimedu, nekudaro kudzivirira kurasikirwa nekukurumidza panguva yekugadzirisa. Izvi zvinowedzera kushanda kwe plaster, kubvumira nguva dzekushandisa dzekushandisa uye kuderedza njodzi yekupaza kana kuderera.
Rheology shanduko: Kuwedzera kweHPMC kunopesvedzera maitiro eRyudology yeGypsum Plaster, kuendesa pseudoplastic kana shear-inotetepa hunhu. Izvi zvinoguma zvaitika mukuvandudzwa, kuderedza kusekerera, uye kuvandudza zvinhu zveiyo, kugonesa kureruka kwekushandisa uye kuwana yunifomu kupedzisa.
Dhezheni yekuwedzera: HPMC inosimudzira kuderera kwe gypsum plaster kune dzakasiyana substrates, kusanganisira masonry, kongiri, uye yakaoma. Kuumbwa kweiyo yakagadzikana interface pakati pePlasters uye substrate inosimudzira bond Simba uye kuderedza kushamwaridzana kana kuumbwa, kunoita kuti kusimba kwenguva refu uye kutendeka kwakarongeka.
Kuisa Nguva Yekudzora Nguva: Nekudzora iyo hydration kinetics yeGypsum, HPMC inogonesa kudzora chaiko pane iyo nguva yekuisa nguva yekugadzira plaster. Izvi zvinobvumidza kurongedza ma profiles yakagadziriswa kune chaiyo application zvinodiwa zvekushandisa, kubva pakukurumidza kuronga kwemabasa enguva yekugara kwenguva refu yekunyora kana basa rekushongedza.
Zvakanakira HPMC muGypsum Plaster Series:
Iko kubatanidzwa kweHPMC kunopa akati wandei zvakanakira Gypsum Plaster Foraster:
Kuvandudzwa Kurovedza: Kuwedzeredza Kwekuchengetwa kwemvura uye rateological zvivakwa zvinokonzeresa svutugadzike, inokatyamadza plaster inosanganisa, kufambisa kusununguka kwekushandisa uye kuderedza marara.
Kuvandudzwa Durability: Superior Donhion uye Kugadza Nguva Yekudzora Kuwedzera Kuwedzera Simba Simba
Zvishandiso Zvekushandisa: HPMC-Modified Gypsum mapuranga anowana mafomu ekuvaka mumabasa akasiyana, kusanganisira zvemukati kupedzisa, kushongedza kuumba, kugadzirisa uye kudzoreredzwa, uye kuzvishongedza
Inoshanda Kufunga uye Nhungamiro Dzinoshanda:
Paunenge uchisanganisira HPMC muGypsum Plaster Foraster, zvinhu zvinoverengeka zvinofanirwa kutariswa kuti unokwanisa kuita basa uye uve nechokwadi chekuenderana:
Kusarudzwa kweHPMC Giredhi: Sarudzo yeHPMC giredhi inofanirwa kuve yakavakirwa pane chaiyo application zvinodiwa
Kuenzanisa Kuedzwa: Kuenzanisa Kuedza Pakati peHPMC uye zvimwe zvinowedzera kana Admixture zvakakosha kuti uongorore zvinogona kuwirirana uye uve nechokwadi chekuita kwaunoda kweiyo plaster yekuumbwa.
Kusanganisa maitiro: Maitiro akakodzera ekusanganisa, kusanganisira kutevedzana kwekuwedzera, zvinofanirwa kutevedzana kudzora kweHPMC uye kugarisana.
HydroxyPropyl methylcellose (HPMC) inoita basa rekuvandudza kuita, kushanda, uye kusimba kwe gypsum plaster. Kuburikidza nekubatanidzwa kwayo kwekuchengetwa kwemvura, renhology kuchinjika, kuishongedza nguva yekudzora, HPMC inobatsira kuwanda uye kuvimbika kweGypsum Plaster muzvinyorwa zvakasiyana siyana zvekuvaka. Nokunzwisisa mabasa uye mabhenefiti eHPMC, varapi vanogona kurongedza mafambiro eplaster kusangana nemhedzisiro yekuvandudzwa kwemabasa ekuvaka emazuva ano uku uchizadzisa hunhu hwepamusoro uye maitiro ekuita.
