Kupfeka kwakavakirwa mumvura vs. kuputira kwakavakirwa pa solvent

Mapendi anowanzo tora zita rawo kubva pa binder, kana resin, yaanobva. Epoxies, alkyds uye urethanes mienzaniso yema resin anopa zita rawo rependi. Asi izvi hazvisi izvo chete zvikamu zvinoumba pendi. Kuwedzera kune zvinowedzerwa, izvo zvinogona kupa pendi mamwe maitiro ekushanda, uye pigments dzinopa ruvara, mapendi anewo chinhu chinonyungudutsa zvese kuita mvura kuti zvive nyore kushandisa.

Chinhu chinonyungudutsa mvura ichi chinowanzo shandiswa semvura kana chimwe chinhu chinonyungudutsa chemakemikari. Saka mazwi ekuti "mvura-yakavakirwa pachinhu" uye "inonyungudutsa-yakavakirwa pachinhu". Rudzi rwechigadzirwa rwakakodzera basa iri runoenderana nemamiriro ezvinhu. Kazhinji, chimwe hachina kunaka pane chimwe, asi chinoshanda zvakasiyana mumamiriro ezvinhu akasiyana. Zvakanaka, sarudzo dzese dziri mbiri dzichavapo pamwe chete muzvigadzirwa zvenyanzvi yekupenda.

Mapendi Akavakirwa Mumvura

Pendi dzinobva mumvura dzinoumba 80 muzana yependi dzinotengeswa pamba nhasi, zvichienderana nePaint Quality Institute, sangano rinopa mazano nekuyedza pendi. Hapana mubvunzo kuti izvi zvinokonzerwa nechimwe chezvinhu zvinonyanya kukwezva zvigadzirwa zvinobva mumvura, kungave pendi yemukati memba kana pendi inodzivirira: kunhuhwirira kushoma.

Pakushanda munzvimbo dzakavharirwa kana dzisina mhepo yakakwana, kupwa kwezvinonyungudutsa kunogona kusafadza vashandi kana kutoita sekuti zvine njodzi kuhutano hwavo. Nekuda kweizvi, mapurojekiti mazhinji akaita seaya anosanganisira matangi ekuchengetera mafuta nemotokari dzechitima anoshandisa machira emvura. Izvi zvinoderedzawo kuwanda kwezvinhu zvinobvira zvinoungana munzvimbo yakavharirwa. Zvisinei, izvi hazvirevi kuti kushandiswa kwemavara emvura kunoderedza kudiwa kweOSHA yakatendera matanho ekuchengetedza nzvimbo dzakavharirwa.

Kutevedzera mitemo yezvakatipoteredza chimwe chikonzero chinowanzo shandiswa pakusarudza kushandisa pendi inogadzirwa nemvura. Zvinyungudutsa zvakawanda zvinopera kuita zvinozivikanwa semakonzo eorganic anoshanduka, kana kuti maVOC. Hurumende dzenyika, dzematunhu nedzemunharaunda dzinowanzo dzora maVOC nekuganhurira huwandu hwemabhizinesi anobvumirwa kuburitsa mukati menguva yakatarwa.EPA inogadza mitemo yenyikakune maVOC, asi mamwe matunhu akatowedzera kuomesa zvirambidzo, zvichiita kuti pave nekuedza kwakasimba kuderedza kuburitswa kwemhepo inoburitsa mweya.

Mapendi emvura haawanzove asina zvinonyungudutsa, zvakadaro. Mazhinji acho ane zvinonzi zvinonyungudutsa, zvinonyungudutsa zviri muhuwandu hwakaderera uye zvakagadzirirwa kubatsira kusundira mvura yasara kubva mupendi painooma. Asi sezvo mapendi emvura asina, kana kuti asina zvinonyungudutsa zvishoma, inzira yakanaka yekuderedza kubuda kweVOC mubhizinesi. Kune mamwe makambani, izvi zvinogona kureva kushandisa mari shoma pakupa mazano ekuchengetedza nharaunda. Kana kuti kudzivirira kuti vasabhadhare faindi huru nekuda kwekupfuura mitengo yeVOC.

ZVINHU ZVAKAVHARWA

Mapendi anonyungudutsa anogadzirwa nezvinhu zvinonyungudutsa mvura zvinofanirwa kupera simba kuburikidza nemakemikari ane oxygen. Kazhinji, kufamba kwemhepo kwakakomberedza chifukidziro chine solvent kunobatsira kukurumidzisa kupindura, zvichideredza nguva yekuoma.

Mapendi aya ane mukana mukuru pane mapendi emvura. Haanyanyi kukanganiswa nemamiriro ekunze akadai sekupisa nehunyoro panguva yekucheneswa. Hunyoro hunogona kudzivirira mvura iri mupendi yemvura kuti isatsve, zvichiita kuti isashande mune dzimwe nzvimbo.

Kuputira kwakavakirwa mumvura kunokonzerawo dambudziko padanho rekugadzirira pamusoro pebasa rekugadzira machira. Mvura, kunyange zvazvo ichitsiva zvinonyungudutsa mune dzimwe nguva, inyaya huru yekugadzirwa kwengura, ndicho chikonzero chikuru cheindasitiri yekugadzira machira mumaindasitiri. Kana mvura ikasangana nechinhu chisati chaiswa machira, ngura inogona kutanga kuitika. Kuti zvive pachena kuti izvi hazvisizvo, machira akavakirwa mumvura anofanira kugadzirwa kuitira kuti mvura yese ibudiswe kuburikidza nefirimu repamusoro isati yaitika ngura. Izvi hazvisi zvekufunga nezvemachira akavakirwa mumvura.

Saka, muchidimbu, kunyange hazvo machira emvura angave sarudzo yakanaka kumabasa anosanganisira nzvimbo dzakamanikana uye kushandiswa kwemavara nguva dzose, haana kusimba. Mabasa ari munzvimbo dzakavhurika, dzine hunyoro, seaya anowanzo kuwanikwa mumapurojekiti ekugadzirisa zvivakwa, anogona kubatsirwa nemavara akakodzera. Kana muchida kukurukura kuti ndechipi chigadzirwa chingave chakanakira purojekiti yenyu, tinoda kunzwa kubva kwamuri.Taura nekambani yeMit-ivy Coatingsnhasi. Kana, kana uchida kutanga watarisa mhando yezvigadzirwa zvedu zvese, dhawunirodha katalogu yedu yezvigadzirwa pazasi.
