Mvura-based coatings vs. solvent-based coatings

Mabhachi anowanzo tora zita rawo kubva kune binder, kana resin, kubva kwaanogadzirwa. Epoxies, alkyds uye urethanes yese mienzaniso yeresin inopa jasi zita ravo. Asi izvi handizvo chete zvikamu zvinoumba jasi. Pamusoro pezvinowedzera, izvo zvinogona kukweretesa yekubikira zvimwe zvivakwa zvekuita, uye pigment inokweretesa ruvara, machira anewo chinhu chinonyungudutsa zvese kuita mvura kuti zvive nyore kushandisa.

Iyi liquefying agent inowanzotora chimiro chemvura kana imwe imwe chemical solvent. Saka mazwi ekuti "water-based" uye "solvent-based". Ndeupi rudzi rwechigadzirwa chakakodzera basa rinoenderana nemamiriro ezvinhu. Kazhinji kutaura, imwe haisi nani pane imwe, asi vanoita zvakasiyana mumamiriro akasiyana. Sezvineiwo, sarudzo dzese dziri mbiri dzichavapo padivi-ne-parutivi mune arsenal yenyanzvi yekuputira.

MASHOKO AKABVA MVURA

Pendi dzinobva mumvura dzinoita zvikamu makumi masere kubva muzana zvependi dzemumba dziri kutengeswa nhasi maererano nePaint Quality Institute, sangano rinopa mazano nekuongorora pendi. Hapana mubvunzo kuti izvi zviri muchikamu chikuru nekuda kwechimwe chezvinonyanya kukwezva zvemvura-based products, ingave iri mukati meimba pendi kana rinorema-basa rekudzivirira rekudzivirira: kunhuhwirira kushoma.

Kana uchishanda munzvimbo dzakavharirwa kana dzisina mhepo isina mhepo zvakanaka, kufefeterwa kwezvinonyungudutsa kunogona kusagadzikana kuvashandi kana kutofuratira zvine njodzi kuhutano hwavo. Nechikonzero ichi, mapurojekiti mazhinji seaya anosanganisira matangi ekuchengetera mafuta uye mota dzechitima dzechitima dzinoshandisa mabhanhire emvura. Izvi zvakare zvinoderedza kuwanda kwezvinhu zvinopisa zvinovaka munzvimbo yakavharwa. Izvozvo hazvirevi, zvisinei, kuti kushandiswa kwemvura-based coatings kunoramba kudiwa kweOSHA yakabvumira matanho ekuchengetedza nzvimbo.

Kuteerera kwezvakatipoteredza ndechimwe chikonzero chakajairika chekusarudza kushandisa mvura-based coating. Zvinyungudutsa zvizhinji zvinonyunguduka kuita izvo zvinonzi volatile organic compounds, kana maVOCs. Hurumende dzenyika, dzematunhu nedzenzvimbo dzinowanzo gadzirisa maVOC nekudzikamisa mangani mabhizinesi anotenderwa kuburitsa munguva yakapihwa. TheEPA inogadza mitemo yenyikayeVOCs, asi dzimwe nyika dzakasimbisa zvirambidzo zvakatowedzera, zvichida kuedza kwakabatana kudzikamisa kuburitsa kwavo.

Mvura-based coatings haifaniri kunge ine zero solvents, zvakadaro. Mazhinji ane izvo zvinodaidzwa kuti co-solvents, zvinonyungudutsa zviripo muzvikamu zvakaderera uye zvinoreva kubatsira kusundira yakasara yemvura kunze kwekunge ichioma. Asi sezvo mvura-yakavakirwa machira aine aiwa, kana akanyanya kushoma zvinonyungudutsa, inzira yakanaka yekudzikisa bhizinesi rekubuda kweVOC. Kune mamwe makambani, izvi zvinogona kureva kushandisa mari shoma pakuraira kwekuteerera kwezvakatipoteredza. Kana kuti vadzivise kubhadhara faindi dzakakosha dzekupfuura maVOC quotas.

SOLVENT-BASED COATINGS

Solvent-based pendi inoumbwa ne liquefying agents izvo zvinofanirwa kunyungudika kuburikidza nekemikari inopindirana neokisijeni. Kazhinji, kufambisa mhepo yakatenderedza solvent-based coating ichabatsira kukurumidza kuita, kuderedza nguva yekuoma.

Aya machira ane mukana mukuru mumwe pamusoro pemvura-based coatings. Ivo havatani kubatwa nemamiriro ekunze akadai sekushisa uye humidity panguva yekurapa chikamu. Humidity inogona chaizvo kudzivirira mvura iri mumvura-based coating kubva pakubuda, zvichiita kuti isashande mune mamwe mamiriro ekunze.

Mvura-based coatings inopawo dambudziko kune yepamusoro prep nhanho yeprojekti yekuputira. Mvura, nepo inovimbisa inotsiva zvinonyungudutsa mune mamwe mamiriro, zvakare chikamu chakakosha chemaitiro ekuora, chikonzero chese cheindasitiri yekupfeka maindasitiri pakutanga. Kana mvura ikasangana ne substrate isati yaiswa, kupisa kwemavara kunogona kutanga kuitika. Kuti uone kuti izvi hazvisi izvo, mvura-based coatings inofanira kugadzirwa kuitira kuti mvura yose ibudiswe kuburikidza nefirimu yepamusoro isati yaitika. Uku hakusi kufunga nezve solvent-based coatings.

Saka, muchidimbu, kunyangwe mabhati emvura anogona kunge ari sarudzo yakanaka yemabasa anosanganisira nzvimbo dzakavharirwa uye anoenderera ekushandisa machira, haana asina kusimba makwapa. Mabasa munzvimbo dzakavhurika, dzakanyorova, senge dzinowanzo wanikwa mumapurojekiti ekudzoreredza zvivakwa, anogona achiri kubatsirikana kubva pakurongeka chaiko. Kana uchida kukurukura kuti ndeupi rudzi rwechigadzirwa chingave chakanakira chirongwa chako, tinoda kunzwa kubva kwauri.Bata ne mit-ivy indasitiri Coatingsnhasi. Kana, kana iwe uchida kutarisa kune yedu yakazara chigadzirwa mutsara kutanga, dhawunirodha yedu chigadzirwa katalogi pazasi.
