HPMC (Hydroxypropyl Methyl Cellulose) is cellulose ether iri kuwana mukurumbira muindasitiri yekuvaka sekuwedzera kune putty. Skim coat iko kushandiswa kwechitsetse chitete chesimende pamusoro penzvimbo yakaoma kuti itsetseke uye kugadzira imwe nzvimbo yakatonyanya. Pano isu tinoongorora mabhenefiti ekushandisa HPMC mune clearcoats.
Chekutanga, HPMC inoita seyakanyorova, zvinoreva kuti inobatsira kuchengetedza skim layer yakanyorova. Izvi zvakakosha nekuti kana zvinhu zvikaoma nekukasira, zvinogona kutsemuka kana kushona, zvichikonzera kusaenzana. Nekuwedzera nguva yekuomesa, HPMC inogona kubatsira kuona kuti majasi e skim anooma zvakanyanya zvakaenzana, zvichikonzera kupera kwakapfava, kwakanyanya kufadza.
Chechipiri, HPMC inoshandawo seyakakora, zvinoreva kuti inogona kubatsira kuwedzera viscosity ye putty. Izvi zvinonyanya kukosha kana uchishanda nezvinhu zvakatetepa kana kuti runny skim-coated, sezvo inogona kubatsira kudzivirira kudonha uye kuve nechokwadi chekunamatira kwakakodzera kwezvinhu kumusoro. Nekuwedzera kuenderana kweiyo putty layer, HPMC inogona zvakare kubatsira kudzikisa mukana wehomwe dzemhepo kuumba mune izvo zvinhu, izvo zvinogona kutungamira mukutsemuka uye kumwe kukanganisa.
Imwe bhenefiti yeHPMC ndeyekuti inogona kubatsira kuvandudza machinability ye putty. Izvi zvinodaro nekuti inoshanda semafuta ekuzora, zvichiita kuti zvive nyore kuisa izvo zvinhu uye nekuona kupararira kwakatowanda kwechinhu pamusoro pepamusoro. Nekuvandudza machinability, HPMC inogona kuchengetedza nguva uye kushanda nesimba panguva yekushandisa, ichiita iyo yakakurumbira sarudzo kune makondirakiti uye DIY vanofarira.
Pamusoro pezvo, HPMC inowirirana zvakanyanya nezvimwe zvinowedzerwa zvinowanzoshandiswa mumavarnishes, zvakadai se latex uye acrylic binders. Izvi zvinoreva kuti inogona kushandiswa pamwe chete nezvinhu izvi kuti uwane chaiwo maitiro ekuita, akadai sekuvandudza kunamatira kana kuramba mvura. Nekusimudzira kushanda kwese kwema putties, HPMC inogona kubatsira kuwedzera hupenyu hwenzvimbo dzakapedzwa uye kuderedza kudiwa kwekugadzirisa kunodhura kana kutsiva.
Mabhenefiti ezvakatipoteredza ekushandisa HPMC anofanirwawo kutaurwa. Seyakasikwa polymer inotorwa kubva ku cellulose, inoodza uye isina chepfu, zvichiita kuti ive yakachengeteka uye inogoneka imwe nzira kune zvekugadzira zvinowedzera. Pamusoro pezvo, sezvo ichinyungudika mumvura, hapana njodzi yekusvibisa mvura yepasi kana mamwe masisitimu emvura panguva yekushandiswa kana kuchenesa.
Mukupedzisa, HPMC ndeye yakawanda inoshanda uye inoshanda putty yekuwedzera ine akatevedzana mabhenefiti maererano nekuchengetedza mvura, kukora, kuvaka, kuenderana uye kusimba. Nekubatanidza HPMC mune yavo skim coating materials, makondirakiti uye maDIYers zvakafanana anogona kuwana akapfava, mamwe mayunifomu epamusoro uye yakagadziridzwa mashandiro uye kusimba.
