Hydroxypropyl methylcellulose (HPMC) chinhu chakakosha mune yakaoma-musanganiswa dhaka maumbirwo uye inoita basa rakakosha mukuvandudza akasiyana dhaka. Dry mix mortar ndeye pre-mixed musanganiswa wefine aggregate, simenti uye additives inongoda kuwedzerwa nemvura panzvimbo yekuvaka. Muchiitiko ichi, HPMC inoshanda sechinhu chinowedzera chinowedzera chinobatsira kuvandudza kushanda uye kushanda kwedhaka.
Kemikari chimiro uye zvivakwa:
HPMC ndeye semi-synthetic polymer inotorwa kubva ku cellulose, yakasikwa polima inowanikwa muchirimwa sero madziro. Kuburikidza nenhevedzano yemakemikari ekugadzirisa, hydroxypropyl uye methyl mapoka anounzwa mukati meselulosi musana kuumba HPMC. Kugadziridzwa uku kunopa HPMC yakasarudzika zvivakwa, ichiita kuti inyungudika mumvura uye ichipa kukora, kunamira, uye kugona kugadzira firimu.
Mabasa eiyo dry mix mortar:
Kuchengeta mvura:
HPMC inokwidziridza kuchengetwa kwemvura kweakaomeswa musanganiswa dhaka, kudzivirira kukurumidza kubuda kwemvura uye kuve nechokwadi chekuti simende hydration yakakodzera. Izvi zvakakosha pakukura kwesimba uye kusimba kwedhaka.
Kukora:
Nekuda kwekukora kwayo zvivakwa, HPMC inowedzera kuwirirana uye kushanda kwedhaka, zvichiita kuti zvive nyore kuisa uye kuita zvirinani panguva yekuvaka.
Natsiridza adhesion:
HPMC inoshanda sebhainda kusimudzira zvirinani kunamatira kwedhaka kune akasiyana substrates. Izvi zvakakosha pakubatanidza kunoshanda kwedhaka kumusoro kwairi kuisirwa.
Deredza sagging:
Kuwedzera HPMC kunobatsira kuderedza kudonha kana kunyura kwedhaka, kunyanya mumashandisirwo akatwasuka. Izvi zvinobatsira kugadzikana uye kufanana kwedhaka rinoshandiswa.
Seta nguva yekudzora:
HPMC inokanganisa nguva yekumisikidza yedhaka. Nekunyatso gadzirisa dosage, kuseta nguva kunogona kudzorwa kuti isangane nezvinodiwa zveprojekiti.
Natsiridza kuchinjika:
Kuvapo kweHPMC kunobatsira kuwedzera kuchinjika kwedhaka uye kunoderedza mukana wekutsemuka. Izvi zvinonyanya kukosha apo iyo substrate inogona kufamba zvishoma.
Enhanced processability:
Kuita kwekuvaka ndicho chinhu chakakosha pakuvaka zvinhu. HPMC inovandudza kushanda kwese kweiyo yakaoma musanganiswa dhaka, zvichiita kuti zvive nyore kubata nekuisa.
Inoramba kudonha uye kudonha:
HPMC inopa dhaka thixotropy, izvo zvinoreva kuti kana ikamutswa kana kushandiswa nesimba, viscosity yayo inoderera, zvichiita kuti zvive nyore kupararira, uye inodzokera kune imwe nzvimbo yakasvibirira kana yakazorora, kudzivirira kudonha kana kudonha.
Nzvimbo dzekushandisa:
HPMC inoshandiswa zvakanyanya mumhando dzakasiyana-siyana dzakaoma musanganiswa wedhaka zvikumbiro zvinosanganisira:
Tile glue
Kupa uye plaster
self-leveling compound
Caulk
dhaka remasonry
EIFS (Exterior Wall Insulation uye Finishing System)
Hydroxypropyl methylcellulose inoshandiswa zvakasiyana-siyana uye inokosha yekuwedzera mune yakaoma musanganiswa dhaka maumbirwo. Hunhu hwayo hwakasiyana hunobatsira kuvandudza kuchengetedza kwemvura, kushanda, kunamatira uye kuita kwese kwedhaka. Sezvo maitiro ekuvaka ari kuramba achishanduka, basa reHPMC mukuvandudza kunaka uye kushanda kweakaoma-musanganiswa dhaka maapplication anogona kuramba akakosha.
