Hydroxypropyl Methylcellulose (HPMC) ether inowanzoshandiswa sechinhu chinowedzera mumichina yekupfapfaidza dhaka maumbirwo nekuda kwehuwandu hwayo hunobatsira. Mechanical spraying mortar, inozivikanwawo sedhaka rakaiswa muchina kana dhaka rinopfapfaidza, rinoshandiswa kuita sekupurasita, kuisa, uye kupeta pamusoro muzvirongwa zvekuvaka. Heano mashandisirwo eHPMC mumakanika yekupfapfaidza dhaka:

1. Kuchengeta Mvura: HPMC inovandudza kuchengetedza kwemvura kwemakanika yekupfapfaidza dhaka. Iyo inoumba firimu rinodzivirira rakakomberedza simenti particles, inonoke kudonha kwemvura uye kuwedzera nguva yekushanda yedhaka. Izvi zvinogonesa hydration yakakwana ye simenti uye inosimudzira kugadzika kwakakodzera uye kunamatira kwedhaka rakapfapfaidzwa kune substrate.
2. Kuwedzeredzwa Kwekushanda: HPMC inoshanda senge rheology modifier, inosimudzira kushanda uye kuyerera zvimiro zvemakanika yekupfapfaidza dhaka. Inovandudza kupararira uye kupomba kwemusanganiswa wedhaka, ichibvumira kushandiswa kwakatsetseka uye kunoenderana kuburikidza nekupfapfaidza michina. Izvi zvinoguma nekuvharika kwakafanana nekukora kwedhaka rakapfapfaidzwa.
3. Adhesion: HPMC inonatsiridza kunamatira kwemakanika yekupfapfaidza dhaka kune akasiyana substrates, kusanganisira kongiri, masonry, zvidhinha, uye simbi. Iyo inosimudzira hukama huri nani pakati pedhaka neiyo substrate, ichidzikisa njodzi yeku delamination kana dhizaini mushure mekushandisa. Izvi zvinovimbisa kugadzika uye kunogara kwenguva refu pamusoro pekuvhara uye kupera.
4. Anti-Sagging Properties: HPMC inobatsira kudzivirira kudonha kana kudonha kwemakanika yekupfapfaidza dhaka panzvimbo yakatwasuka kana pamusoro. Iyo inowedzera viscosity uye goho kushushikana kwemusanganiswa wedhaka, ichibvumira kuti inamate kune yakatwasuka nzvimbo pasina yakawandisa deformation kana kutama panguva yekushandisa.
5. Crack Resistance: HPMC inosimudzira kuchinjika uye kubatana kwemakanika yekupfapfaidza dhaka, ichideredza mukana wekutsemuka kana kupera mushure mekushandisa. Iyo inogadzika kufamba kudiki uye kuwedzera mu substrate pasina kukanganisa kutendeseka kweakapfapfaidzwa dhaka layer, kuve nechokwadi kuti yakatsetseka uye isina-yakapwanyika kupera.
6. Kuenderana neZviwedzerwa: HPMC inowirirana neakasiyana ekuwedzera anowanzo shandiswa mumichina yekupfapfaidza dhaka maumbirwo, senge air-entraining agents, plasticizers, uye accelerators. Inobvumira kugadziridzwa kwezvivakwa zvevhu kuti isangane nezvinodiwa zvekuita uye zvinodiwa zvekushandisa.
7. Zviri nyore Kusanganisa uye Kubata: HPMC inowanikwa muhupfu uye inogona kuparadzirwa nyore nyore uye yakasanganiswa nezvimwe zvakaoma zvinosanganiswa isati yawedzera mvura. Kuenderana kwayo nemvura-yakavakirwa masisitimu inorerutsa nzira yekusanganisa uye inova nechokwadi chekugovera yunifomu yezvinowedzera mukati memusanganiswa wedhaka. Izvi zvinogonesa kugadzirira uye kubata kwemakanika yekupfapfaidza dhaka panzvimbo dzekuvaka.
8. Mafungiro Ezvakatipoteredza: HPMC ine hushamwari kwezvakatipoteredza uye haina chepfu, ichiita kuti ive yakakodzera kushandiswa mukuvaka zvikumbiro pasina kuisa njodzi kuhutano hwevanhu kana nharaunda.

HPMC inoita basa rakakosha mukuvandudza mashandiro, kushanda nesimba, kunamatira, uye kusimba kwemechini yekupfapfaidza dhaka, kuve nechokwadi chepamusoro uye chemhando yepamusoro yekupfeka uye kupera muzvirongwa zvekuvaka.
