Hydroxyprusyl methylcellose (HPMC) Gypsum-based Plaster uye Gypsum zvigadzirwa

HydroxyPropyl methylcellose (HPMC), seyakajairika cellulose ether, iri kuwedzera kushandiswa mune zvekuvakisa, kunyanya muGypsum-based plaster uye gypsum zvigadzirwa. HPMC ine yakanaka mvura solubility, kuremedza, kudzokorora kwemvura uye mafirimu-ekugadzira zvinhu, uye saka anoita basa rakakosha mukugadzirwa uye kushandiswa kwezvinhu zveGypsum.

Basic Staket of HydroxyPropyl Methylcellose (HPMC)
HPMC ndeye isiri-ionic cellulose ether, inotumidzwa mushure mekutanga kwehydroxypruppropropropropropropropropyl uye methyl mapoka pane cellulose molecule. Zvivakwa zvaro zvinosanganisira:

Solubility: HPMC inogona kunyungudika nekukurumidza mumvura inotonhora kuti iite pachena kana zvishoma turbid colodal solution.
Kukakavara: HPMC ine yakanaka kwazvo mhedzisiro uye inogona kuwedzera iyo visikopa yemhinduro.
Kuchengeta kwemvura: HPMC inogona kuramba yakanyorova kwenguva yakareba kana mvura ichiputira, ichidzivirira mvura kubva pakurasikirwa nekukurumidza.
Firimu-fomu: HPMC inogona kuumba firimu rinoshanduka uye rinojeka mushure mekuoma.
Aya maitiro anogadzira HPMC yakakosha muTripsum-based plaster uye gypsum zvigadzirwa.

Kushandiswa kweHPMC muGypsum-based Plaster
Gypsum-based Plaster yakashandiswa-mukati mekushandiswa kwemukati uye yekudzoreredza zvinyorwa zvinyorwa muzvivakwa zvemazuva ano, inonyanya kuumbwa neye-hydrate gypsum, aggreatates uye dzakasiyana siyana. Iko kushandiswa kweHPMC muGypsum-based plaster inonyanya kuratidzwa mune zvinotevera zvinhu:

Kuita kwakasimba: HPMC inogona kuwedzera zvakanyanya vhiza yeGypsum-based plaster, ichiita kuti plaster yakawanda iripo panguva yekuvaka uye kudzivirira kusimuka uye sag.
Kudzokorora Kwekuchengetwa Kwekuita: Nekuda kwekuremekedza kwemvura
Kuvandudza Kuita Kwekuvaka: HPMC inogona kuvandudza iyo lubricity uye fluidity yeiyo gypsum-based plaster, zvichiita kuti zvive nyore kupararira uye nekutsetseka pakuvaka, kuderedza kuomarara nekuvandudza kushanda kwekuvaka.
Crack Kudzikisira: Nekuwedzera kushanduka kweplaster, HPMC inogona kuderedza zvinobudirira kupaza yakakonzerwa nekudziya kwebasa rebasa rekushongedza.

Kushandiswa kweHPMC mune Gypsum zvigadzirwa
Pamusoro pekushandisa kwayo muGypsum-based plaster, HPMC zvakare yakashandiswa zvakanyanya muzvivakwa zveGypsum, yakadaro

Kugadziridzwa uye kuremerwa: Kuwedzera HPMC kuGypsum Slurry kunogona kuvandudza zvivakwa zvaro, ita kuti slandotropy yekuzadza zvivakwa, kuderedza mabhuruku uye kuremara, uye kuvandudza chimiro chechigadzirwa chakapera.
Kuvandudza kuoma uye Simba: Iyo firimu chimiro yakaumbwa neHPMC panguva yekuomesa inogona kuwedzera iyo yekuchinja uye kukanganisa kwezvinhu zveGypsum uye kuderedza kukuvara panguva yekufambisa uye kuisirwa.
Kuvandudza Kuchengetwa Kwemvura: HPMC inogona kuchengetedza mamiriro akareba kwenguva yakareba panguva yekuomesa zvigadzirwa zveGypsum zvigadzirwa, kudzivisa kupaza uye deformation inokonzerwa nekuomesa kwakanyanya.
Yunifomu kuumbwa: HPMC inogona kuita iyo gypsum slurry yakagoverwa muumbi, kuvandudza density uye kufanana kwechigadzirwa, uye chengetedza kurongeka kwekupedzisira uye kupedzisa kwechigadzirwa.

Iko kushandiswa kwehydroxypropyl methylcellose (HPMC) muGypsum-based Plaster uye Gypsum zvigadzirwa zvine zvakanakira zvakakosha. Nekuvandudza kuchinjisa, kuumbwa kwemvura, kuumbwa kwemvura uye zvimwe zvivakwa, HPMC kwete kungovandudza mari yekuvaka uye yakapedza zvigadzirwa zvechigadzirwa, asi zvakare inowedzera hupenyu hwebasa rezvigadzirwa zveGypsum. Mukutsvaga mune ramangwana uye kushanduka kwezvinhu zvekuvakisa, Hpmc, seyakakosha inoshanda inoshanda, icharamba ichitamba basa rayo rakasiyana uye rinoita mipiro yakakura yekuvandudza kweindasitiri yekuvaka.
