Gypsum-based yakaoma yakaoma musanganiswa mortar inowedzera hpmc

Gypsum-based yakaoma musanganiswa musanganiswa muchikamu chakakosha muindasitiri yekuvaka, inoshandiswa kune dzakasiyana-siyana manyorerwo akadai sekuparadza, masonry, uye kupedzisa. Kusimudzira maitiro ayo uye zvivakwa, zvinodhakwa senge hydroxypruslEl methylcellose (HPMC) zvinowanzobatanidzwa mumusanganiswa.

1.Todyt

Gypsum-based yakaoma musanganiswa musanganiswa usati wasanganiswa-wakasanganiswa wakasangana neakanakisa aggregates, zvinhu zvemasimudziro (kazhinji gypsum), zvinowedzera zvemakemikari, uye dzimwe nguva polymers. Kana ikasanganiswa nemvura panzvimbo yekuvaka, inoumba iyo inoshanda iyo inogona kuiswa zvakananga kune dzakasiyana siyana. Iyi motsi inopa akati wandei zvakanakira pamusoro petsika yakanyorova monganda monganda, kusanganisira kusununguka kwekushandisa, yakaderedzwa kurapa nguva, uye hunhu hunoenderana.

2.Role yekuwedzera muGypsum-yakavakirwa yakaoma musanganiswa moturu:

Kuzvidzwa kunotamba basa rakakosha mukuvandudza mashandiro eGypsum-based yakaoma musanganiswa muhomwe. Ivo vanogona kuvandudza kudzorera, kudenha, kuchengetwa kwemvura, kurongedza nguva, uye nemuchina simba. Imwe yekuwedzera kwakadaro inoshandiswa zvakanyanya muumbi mafambiro ndeye hydroxypropyl methylcellose (HPMC).

3.hydroxyprondPropyl methylcellose (HPMC):

HPMC ndeye cellulose ether inotorwa kubva kune yakasikwa cellulose. Izvo zvinowanzoshandiswa mune zvekuvaka zvakakonzerwa nekuchengetedza kwayo kwemvura yekuchengetwa kwemvura, kugona kwakasimba, uye kuderera kuvandudza. MuGypsum-based yakaoma musanganiswa musanganiswa, HPMC zviito senge rheology modifier, ichivandudza kuenderana uye kushanda kwemusanganiswa.

4.Properties yeHPMC:

Kuchengeta kwemvura: HPMC inoumba firimu rekudzivirira kutenderedza zvikamu zvechikamu, zvichidzivirira nekukurumidza kwemvura. Izvi zvinovimbisa yunifomu yekunyora kweiyo simende, zvichikonzera kuvandudzwa kwesimba simba uye kuderedza kupaza.
Kukakavara: HPMC inokwenenzvera mongwe, ichidzivirira kusimuka uye ichiratidza kuti iri nani kushandiswa pamadziro nemazere.
Adhisheni: HPMC inosimudzira iyo yekushambadzira yeiyo demo kune dzakasiyana-siyana substrates, kusanganisira kongiri, masonry, uye plasterboard.
Kumisikidza nguva: Nekudzora chiyero che hydration, HPMC inogona kugadzirisa nguva yekuisa duri, kubvumira nguva yakakwana yekushandisa uye kupedzisa.
Kuvandudzwa Kurovedza: HPMC inopa basa riri nani kune dhiri, zvichiita kuti zvive nyore kupararira, trowel, uye kupedzisa.

5.Benefits yeHPMC muGypsum-yakavakirwa yakaoma musanganiswa musanganiswa:

Yakavandudzwa Workability: HPMC inovandudza kupararira uye kuwirirana kweiyo dhaka, zvichiita kuti zvive nyore kushandisa uye chimiro.
Yakaderedzwa Shrinkage: Nekuchengetedza mvura mukati merudzi, HPMC inobatsira kuderedza kudzima marara, zvichitungamira kune kupedza uye kwakanyanya kusimba.
Kuvandudzwa Bond Simba: Iyo inonamira zvivakwa zveHPMC inokurudzira kusungwa zviri nani pakati pehudyu uye substrate, ichiratidza kuderera kwenguva refu.
Kuenderana kwekuita: Kusanganisira HPMC inosimbisa yunifomu zvivakwa uye kuita kweiyo moter batch kuti batch.
Kuedza: HPMC inogona kushandiswa mune dzakasiyana-siyana mafomu uye zvinoshandiswa, zvichiita kuti zviwedzere kuverenga kune gypsum-based yakaoma musanganiswa musanganiswa.

6.6Application yeGypsum-yakavakirwa yakaoma musanganiswa musanganiswa neHPMC:

Plastering: HPMC-yakagadziridzwa mongwe inowanzoshandiswa yemukati uye yekudzima mapepa ekushandisa nekuda kwekushanda kwayo kwakanakisa uye kushamisika.
Masonry: HPMC inowedzera kusimbisa kusimba kwemutema mukuvaka kwekuvaka, kuvandudza kutendeka kwechimiro.
Kupedzisa: HPMC inobatsira kuzadzisa yakatsiga uye yunifomu kupera pamadziro nemadziro, kuishandira aesthetics yechivako.
Gadzirisa uye Kugadziridzwa: HPMC-yakagadziriswa motars yakakodzera kugadzirisa uye kugadzirisa mapurojekiti, kupa yakanakisa kujairika kune iripo substrates.

HydroxyPropyl methylcellose (HPMC) inyaya yakakosha muGypsum-yakavakirwa yakaoma musanganiswa moterar mafomu. Zvivakwa zvaro zvakasarudzika zvinovandudza basa rekushanda, kudenha, kudzokorora kwemvura, uye kugara nguva, zvichikonzera hunhu hwakanyanya, hwakasimba, uye nyore-kushandisa motokari. Nezvekuita zvinoenderana uye zvakanaka, Hpmc inoita basa rakakura mukuita kwemazuva ano zvekuvaka, zvichikonzera kugona uye kusakwana uye kuzadza kwezvivakwa zvekuvaka.
