HPMC (Hydroxypropyl Methyl Cellulose) i cellulose ether iri kuwana mukurumbira muindasitiri yekuvaka sechinhu chinowedzera putty. Skim coat kushandisa jira rakatetepa resimende pamusoro penzvimbo isina kusimba kuti iite kuti ive yakaenzana. Pano tinoongorora mabhenefiti ekushandisa HPMC muma clearcoats.
Chekutanga, HPMC inoshanda semushonga unobvisa hunyoro, zvichireva kuti inobatsira kuchengetedza jira rakanyorova. Izvi zvakakosha nekuti kana jira rikaoma nekukurumidza, rinogona kutsemuka kana kupfupika, zvichikonzera kuti pamusoro paro pasave nechinhu chakaenzana. Nekuwedzera nguva yekuoma, HPMC inogona kubatsira kuona kuti jira rakanyorova rinooma zvakaenzana, zvichiita kuti rive rakatsetseka uye rinoyevedza.
Chechipiri, HPMC inoshandawo sechinhu chinosimbisa kukora, zvichireva kuti inogona kubatsira kuwedzera kusimba kweputty. Izvi zvinonyanya kubatsira pakushanda nezvinhu zvakatetepa kana zvinoyerera zvakaputirwa nemafuta, sezvo zvichigona kubatsira kudzivirira madonhwe emvura uye kuona kuti chinhu chacho chinonamira zvakanaka pamusoro. Nekuwedzera kugadzikana kweputty layer, HPMC inogonawo kubatsira kuderedza mukana wekuti mapombi emhepo aumbe muchinhu chacho, izvo zvinogona kukonzera kutsemuka nezvimwe zvikanganiso.
Imwe bhenefiti yeHPMC ndeyekuti inogona kubatsira kuvandudza mashandiro eputty. Izvi zvinodaro nekuti inoshanda semafuta, zvichiita kuti zvive nyore kuisa zvinhu uye kuve nechokwadi chekuti zvinhu zvinopararira zvakaenzana pamusoro. Nekuvandudza mashandiro ekugadzira, HPMC inogona kuchengetedza nguva nesimba panguva yekuisa, zvichiita kuti ive sarudzo inozivikanwa kune vanogadzira zvinhu uye vanofarira DIY.
Pamusoro pezvo, HPMC inoenderana zvakanyanya nezvimwe zvinoshandiswa muvarnish, zvakaita se latex ne acrylic binders. Izvi zvinoreva kuti inogona kushandiswa pamwe chete nezvinhu izvi kuti iwane hunhu hwayo hwekushanda, hwakadai sekunamira kwakasimba kana kuramba mvura. Nekuwedzera kushanda kwese kwe putty, HPMC inogona kubatsira kuwedzera hupenyu hwenzvimbo dzakapedzwa uye kuderedza kudiwa kwekugadzirisa kunodhura kana kutsiva.
Zvakanakira zvekushandisa HPMC zvakatipoteredza zvakakoshawo kutaura nezvazvo. Sepolymer yechisikigo inobva mu cellulose, inogona kuora uye haina chepfu, zvichiita kuti ive imwe nzira yakachengeteka uye inogara kwenguva refu pane zvekuwedzera zvakagadzirwa. Pamusoro pezvo, sezvo ichinyungudika mumvura, hapana njodzi yekusvibisa mvura yepasi kana mamwe masisitimu emvura panguva yekuisa kana kuchenesa.
Mukupedzisa, HPMC chinhu chinobatsira pakugadzira putty chinoshanda zvakawanda uye chinoshanda zvakanaka chine zvakanakira zvakawanda maererano nekuchengetedza mvura, kukora, kuvaka, kuenderana uye kugara kwenguva refu. Nekuisa HPMC muzvinhu zvavo zvekufukidza zvakapfava, makondirakiti nevanogadzira zvinhu zvekugadzira vanogona kuwana nzvimbo dzakapfava, dzakafanana uye kushanda zvakanaka uye kugara kwenguva refu.
