Kukosha kwemvura-based coatings:
Chekutanga, hunhu hwependi yemvura ndeyekuti ine mamwe maitiro emvura, ayo akasiyana nependi yechinyakare, asi mvura chinhu chatinoziva tese muhupenyu hwedu.Zvingave zvekuwachira, kubika kana kunwa, hazviparadzanisiki kubva pairi, saka pendi yemvura mumhando iyi yepende inogona kungoratidza maitiro ayo semvura, asi kubudirira kwayo kwechokwadi kunowanikwa mukuderedza chikamu chezvinonyungudutsa mupende. kana kunyange kutsiva zvachose organic solvents.Chikonzero cheichi mhedziso ndechekuti organic solvents iri mumachira echinyakare yakaunza dambudziko rakawandisa kuhupenyu hwevanhu, asi kusati kwabuda kwemvura-yakavakirwa mabhanhire, vanhu vanofanirwa kubvuma mhedzisiro yakaipa yekupfeka yechinyakare.
Chechipiri, zvakanakira mvura-yakavakirwa pendi hazvigumiri pakuchengetedza nharaunda, zvinogona zvakare kuchengetedza vashandi vekuvaka.Vashandi vanoshanda muindastiri yependi vanofanira kunge vaine chepfu yakawanda kana shoma nependi yechinyakare, uye vamwe vanhu vakatosangana nemoto unopfuta zvinhu.Kubuda kwemvura-based coatings kwaita kuti kurapwa kusiri-chepfu kuve nyore uye kushomeka kune vashandi.Nekuda kwezvakatipoteredza, zvinounzawo hutano kune avo vanoshanda kumberi.
Pakupedzisira, maererano nemutengo, mabhanhire emvura ane mari yakawanda uye inoshanda-inoshanda.Iwo organic zvinonyungudutsa zviri muzvinonyungudutsa zvechinyakare zvinodzivirirwa nepetroleum, nepo mvura-yakavakirwa mabhanhire iine zvishoma kwazvo organic zvinonyungudutsa, kana kunyange isina zvakananga ine organic zvinonyungudutsa, saka kurambidzwa kwacho kudiki, uye mutengo wakachipa zvakanyanya.Naizvozvo, zvichienzaniswa nekushandiswa kweorganic solvents, inobatwa nemutengo wemafuta kune dzimwe nyika.Kugadzira uye kugadzira maji-based coatings uri wega kwakafanana nekubvarura kubva pamaketani.Chero ani anogona kuvandudza yavo yemvura-yakavakirwa majasi uye nekuashandisa zvakanyanya anogona kurerutsa iyo shoma petrochemical indasitiri.Dzvinyiriro yekugadzira zvinonyungudutsa zvemagetsi zvemagetsi zvinogonawo kuunza pundutso huru kuhupfumi hwenyika hunotevera.Zvinogona kuonekwa kubva pane izvi kuti kugadzirwa kwemvura-based coatings haisi kungoitika mumhizha yekuputira, asiwo nzira itsva yenyika yekuvandudza kukwikwidzana kwavo uye kurerutsa kumanikidzwa kwepetrochemical energy.
Tarisiro yekuvandudzwa kwemvura-based coatings:
Kuvandudzwa kwemvura-based coatings munyika dzakasiyana-siyana kuchiri mukutsvaga.Nhasi, chikamu chemvura-based coatings muindasitiri nedzimwe minda ichiri diki.Zvinhu zvakasiyana-siyana zviri kukanganisa kugadzirwa kwemvura-based coatings.Zvishoma nezvishoma, kutengesa kwemvura-based coatings munyika dzakabudirira kunogona kuverenga nezve 80%, asi 40% chete munyika dzichiri kusimukira, izvo zvinoratidza kusiyana pakati penyika mukugadzirwa kwemvura-based coatings.Zvisinei, mumakore achangopfuura, kuiswa kwemitemo yenyika yekuchengetedzwa kwezvakatipoteredza uye kuvandudzwa kwekuziva kwevanhu nezvekuchengetedzwa kwezvakatipoteredza munyika dzakasiyana-siyana zvakakurudzira kugadzirwa kwemvura-based coatings.Vazhinji uye vechidiki vakawanda vanobatanidzwa mukutsvakurudza kwemvura-based coatings.Kubudirira kweramangwana remvura-based coatings munyika ichave yakanaka kwazvo.
Panguva imwecheteyo, kushayikwa kwepetrochemical simba kwakaunza mikana mitsva yekuvandudzwa kwemvura-based coatings.Nekuda kwekuti zviwanikwa zvepetroleum zviwanikwa zvisingadzokerike, mumamiriro ekuwedzera kwekushomeka kwemafuta epetroleum, mutengo wemafuta epasi rose uri kukwira nekukurumidza, uye mitengo yezvigadzirwa zvine chekuita nemafuta inowedzerawo saizvozvo.Panguva ino, vanhu vakacherechedza zvakanakira mvura-based coatings, saka mumakore achangopfuura, kune yakawanda uye yakawanda mienzaniso yekushandisa mvura-based coatings mukugadzirwa kwemaindasitiri.Maererano nemitemo yekuchengetedzwa kwezvakatipoteredza yenyika dzakasiyana-siyana pasi rose, maitiro emvura-based coatings anogona kupindura zvakanaka kudana kwayo, iyo isingawanzoitiki mukana wekusimudzira.
