Nei HPMC ichikosha mune wet musanganiswa dhaka?

Hydroxypropylmethylcellulose (HPMC) chinhu chakakosha chekuwedzera chinoshandiswa mune zvese zvakaoma-musanganiswa uye wet-musanganiswa dhaka application.Wet-mix mortar idhaka rinogara rakasanganiswa nemvura risati ravakwa, nepo dry-mix mortar inoda kuti mvura iwedzere panzvimbo yekuvaka.HPMC inonatsiridza dzinoverengeka zvivakwa zvemisanganiswa iyi, kusanganisira kushanda, kuchengetedza mvura, nguva yekuisa, simba uye kunamatira.

Vandudza kushanda

Chokutanga uye chakakosha, HPMC inovandudza kushanda kwemvura-musanganiswa dhaka.Kushanda (workability) zvinoreva kuti dhaka rinogona kuiswa nekuumbwa zviri nyore pasina kurasikirwa nehunhu hwayo.Kana ichishandiswa zvine mwero, HPMC inogona kubatsira dhaka kuchengetedza kuenderana, kunoshanda kunoenderana.Izvi zvinonyanya kukosha mukunyorova kusanganisa dhaka maapplication sezvo ivo vachifanira kukwanisa kuumbwa uye kuumbwa zvakanaka pasina kurasikirwa kwezvinhu zvakakosha.

kuchengetedza mvura

Imwe yemabhenefiti makuru eHPMC mune wet musanganiswa dhaka kugona kwayo kuwedzera kuchengetwa kwemvura.Kuchengetedzwa kwemvura (water retention) zvinoreva kugona kwedhaka kuchengetedza mvura inenge yasanganiswa nayo kuitira kuti idiwe nemvura uye ichiporeswa.Kana HPMC yawedzerwa kune yakanyorova musanganiswa dhaka, inogadzira chipingamupinyi pakati pedhaka nenzvimbo yakatenderedza, ichideredza mwero wekubuda kwemvura.Nekuda kweizvozvo, iyo dhaka inogona kunyatsorapwa uye kuwana inodiwa simba uye zvivakwa.

nguva yekusimbisa

HPMC inogona zvakare kubatsira kudzora nguva yekumisikidza yemvura yakasanganiswa madhaka.Kuisa nguva ndiyo nguva inotora kuti dhaka ritange kuoma nekuoma.HPMC inoderedza nguva yekuisa, ichibvumira nguva yakawanda yekushanda nedhaka isati yagadzika.Izvi zvinonyanya kukosha nekunyorova kusanganisa madhaka, sezvo nzira yavo yekuvaka inoda nguva yakawanda yekuumba uye kuseta.

Simba uye Kunamatira

HPMC inogonawo kuvandudza simba uye kunamatira kwemvura-musanganiswa dhaka.Kuwedzera simba kunoreva kuti dhaka rinokwanisa kumira zvirinani kumanikidza uye mamwe masimba ekunze nekufamba kwenguva.Kunatsiridza kunamatira kunoreva kuti dhaka rinonamatira zvirinani kune substrate, ichigadzira chisungo chakasimba.Nekuwedzera HPMC kune yakanyorova musanganiswa dhaka, vashandisi vanogona kuwana yakakwira mazinga esimba uye kunamatira, zvichiita kuti chigadzirwa chakapedzwa chiwedzere kusimba.

Kuenderana nezvimwe zvinowedzera

Chekupedzisira, HPMC inoenderana neyakasiyana-siyana yezvimwe zvinowedzera zvinowanzo shandiswa munyoro musanganiswa dhaka.Izvi zvinosanganisira plasticizers, air-entraining agents uye mamwe thickening agents.Nekubatanidza zvakasiyana-siyana zvekuwedzera, vashandisi vanogona kugadzirisa zvivakwa zvemvura inosanganiswa dhaka kuti isangane nezvinodiwa zveprojekiti.

Mukupedzisa, Hydroxypropyl Methyl Cellulose (HPMC) inovandudza kushanda, kuchengetedza mvura, nguva yekuisa, simba uye kunamatira uye chinhu chakakosha chekuwedzera mune wet mix mortar applications.Kuenderana kwayo nezvimwe zvinowedzera zvinopa vashandisi mukana wekugadzirisa dhaka kuti isangane nezvinodiwa zveprojekiti.Nekubatanidza HPMC mune wet mix mortar formulations, vashandisi vanogona kuwana yakakwira nhanho dzekuita uye kusimba, zvichikonzera emhando yepamusoro zvigadzirwa zvakapedzwa.
