Kufurira kweHPMC Viscosity uye Fineness pane Mortar Performance

Iyo viscosity uye kunaka kweHydroxypropyl Methylcellulose (HPMC) inogona kukanganisa zvakanyanya kushanda kwedhaka.Heano maitiro ega ega parameter anogona kukanganisa kuita kwedhaka:

1. Viscosity:
   • Kuchengeta Mvura: Yakakwira viscosity HPMC mamakisi anowanzo kuchengetedza mvura yakawanda mumusanganiswa wedhaka.Izvi zvakagadziridzwa kuchengetedza mvura zvinogona kuvandudza kushanda, kuwedzera nguva yakazaruka, uye kuderedza njodzi yekuoma nguva isati yakwana, iyo inonyanya kubatsira mumamiriro ekupisa uye akaoma.
   • Yakavandudzwa Adhesion: HPMC ine yakakwirira viscosity inoumba gobvu uye rakabatana firimu pamusoro pezvimedu, zvichikonzera kunamira kwakagadziridzwa pakati pezvinhu zvedhaka, senge aggregates uye mabhainda.Izvi zvinoguma nekuwedzerwa simba rezvisungo uye kuderedzwa kwengozi ye delamination.
   • Yakaderedzwa Sagging: Yepamusoro viscosity HPMC inobatsira kudzikisa tsika yedhaka kuti isag kana kudonha kana yaiswa yakatwasuka.Izvi zvinonyanya kukosha mupamusoro kana vertical application apo dhaka inoda kuchengetedza chimiro chayo uye kunamatira kune substrate.
   • Kuwedzeredzwa Kushanda: HPMC ine viscosity yakakodzera inopa inodiwa rheological zvimiro kudhaka, zvichibvumira kusanganisa nyore, kupomba, uye kushandisa.Inovandudza kupararira uye kubatana kwedhaka, kuita kuti kusungirirwa kwakakodzera uye kupedza.
   • Mhedzisiro paMhepo Yemukati: Yakanyanya kukwirisa viscosity HPMC inogona kutadzisa kupinda kwemhepo mumusanganiswa wedhaka, zvichikanganisa kuomesa kwayo-kunyorova uye kusimba.Naizvozvo, zvakakosha kuenzanisa viscosity nezvimwe zvivakwa kuti ive nechokwadi chekupinda kwemhepo.
2. Fineness:
   • Particle Dispersion: Finer particles eHPMC anowanzo kupararira zvakanyanya kufanana mumatope matrix, zvichikonzera kufambiswa kwakanaka uye kushanda kwepolymer mumusanganiswa wese.Izvi zvinoguma nekuwedzera kuenderana kwekuita zvinhu, sekuchengetedza mvura uye kunamatira.
   • Yakadzikira Njodzi Yekubhera: Finer HPMC zvimedu zvine zvirinani zvekunyorova zvivakwa uye hazvinyanyi kuumba agglomerates kana "mabhora" mumusanganiswa wedhaka.Izvi zvinoderedza njodzi yekusaenzana kugovera uye inova nechokwadi chekuti hydration uye activation yepolymer.
   • Surface Smoothness: Yakanatswa HPMC zvimedu zvinopa kune yakatsetseka yedhaka nzvimbo, kuderedza mukana wehurema hwepamusoro senge pinholes kana makatsemuka.Izvi zvinowedzera kutaridzika kwechigadzirwa chakapedzwa uye kunovandudza huwandu hwese.
   • Kuenderana Nezvimwe Zviwedzerwa: Finer HPMC zvimedu zvinowirirana nezvimwe zvinowedzera zvinowanzo shandiswa mukugadzira dhaka, senge sementitious zvinhu, admixtures, uye pigment.Izvi zvinobvumira kuiswa nyore nyore uye kunovimbisa homogeneity yemusanganiswa.

Muchidimbu, zvese viscosity uye kunaka kweHPMC kunoita basa rakakosha mukuona kuita kwedhaka.Sarudzo chaiyo uye optimization yeaya ma paramita anogona kutungamira mukuvandudza kushanda, kunamatira, sag kuramba, uye huwandu hwese hwedhaka.Izvo zvakakosha kuti utarise zvakanangana nezvinodiwa zvekushandisa uye mamiriro kana uchisarudza yakakodzera HPMC giredhi kune yakapihwa dhaka kugadzirwa.
