Hydroxypropylmethylcellulose (HPMC) chinhu chinoshandiswa zvakasiyana-siyana chinoshandiswa zvakanyanya muindasitiri yekuvaka.Iyo organic polymer inotorwa kubva ku cellulose uye inoshandiswa semvura-inonyungudika thickener, binder uye firimu rekare.HPMC inoita basa rakakosha mukugadzirwa kwemvura-inodzivirira putty poda, iyo inoshandiswa zvakanyanya mumunda wekuvaka.
Mvura inodzivirira putty poda inonamira inoshandiswa mukuvaka zvivakwa kuzadza mapundu, makatsemuka nemakomba mumadziro, simende, kongiri, stucco uye mamwe mapeji.Inonyanya kushandiswa kugadzira nzvimbo yakatsetseka yekupenda, kuvepa Wallpaper kana tiling.Mvura-resistant putty poda inotariswa zvakanyanya nekuda kwekugona kwayo kurwisa unyoro, ichiita iyo inofanirwa-iine zvinhu zvekugezera, makicheni uye dzimwe nzvimbo dzakanyorova.
Pane zvakati wandei zvakanakira kushandisa HPMC mumvura inodzivirira putty poda.
HPMC inyanzvi yekuchengetedza mvura, iyo inogona kuwedzera kushanda kwemvura inodzinga inowanzoshandiswa muputty powder.Inobatsirawo kudzivirira hunyoro kubva pakupinda putty kwenguva refu, yakasimba kupera.Pamusoro pezvo, HPMC ndeye firimu rekare rinogadzira chipingamupinyi chekudzivirira pamusoro peiyo putty, kudzivirira mvura kubva mukati uye kukonzera kukanganisa.
Imwe bhenefiti yeHPMC mumvura-inodzivirira putty poda ndeyekusimbisa chisungo chesimba reiyo putty uye kunatsiridza kunamatira kwayo kune substrate.Ichi chivakwa chinoita kuti HPMC ive chinhu chakakosha mukuumbwa kweputty, kuve nechokwadi chekuti putty inonamira zvakasimba kumusoro uye haina kuputika kana kuputsika nekufamba kwenguva.Nekuwedzera kweHPMC, poda isingadzivirirwe nemvura inova yakagadzikana, yakasimba uye iri nyore kushandisa, zvichiita kuti ive sarudzo yakakurumbira pakati pevashandi vekuvaka.
Pamusoro pezvimiro zvayo zvekudzivirira mvura, HPMC inewo mhedzisiro inobatsira pakukanganisa kwezvakatipoteredza kwemvura inodzivirira putty poda.Yayo biodegradable hunhu inovimbisa kuti putty ine hushamwari kwezvakatipoteredza uye haina kukuvadza nharaunda.HPMC hainawo chepfu uye haiburitse chero hutsi hunokuvadza kana hwema, zvichiita kuti ive yakachengeteka kushandiswa muzvivakwa nedzimba.
Kushandiswa kwehydroxypropyl methylcellulose (HPMC) mumvura-inodzivirira putty powders chinhu chakakosha mumhizha yekuvaka.Yayo inodzivirira mvura uye inonamira zvimiro inoita kuti ive chinhu chakanakisa cheputty, ichipa iyo inogara-yakareba, yakasimba kupera iyo inopesana nehunyoro uye kwezvakatipoteredza kupfeka.Uyezve, ine biodegradable uye isiri-chepfu, zvichiita kuti ive imwe nzira ine hushamwari nharaunda yakachengeteka kushandisa munzvimbo dzeveruzhinji.Nekushandisa HPMC, tinogona kuvaka zvivakwa zvine kusimba kukuru, kugadzikana uye kusimba.
