Zovala zokhala ndi madzi motsutsana ndi zokutira zosungunulira

Zopaka nthawi zambiri zimatenga dzina lake kuchokera ku binder, kapena utomoni, womwe amapangidwira. Ma epoxies, alkyds ndi urethanes onse ndi zitsanzo za utomoni womwe umapereka zokutira dzina lawo. Koma izi sizinthu zokhazo zomwe zimapanga zokutira. Kuphatikiza pazowonjezera, zomwe zimatha kubwereketsa zokutira zinthu zina zogwirira ntchito, ndi ma pigment omwe amabwereketsa mtundu, zokutira zimakhalanso ndi chinthu chomwe chimasungunula zonse kukhala madzi kuti zigwiritsidwe ntchito mosavuta.

Izi zimapangidwira ngati madzi kapena zosungunulira zina. Chifukwa chake mawu akuti "otengera madzi" ndi "zosungunulira". Ndi mtundu wanji wa mankhwala omwe ali oyenera ntchitoyo zimadalira momwe zinthu zilili. Nthawi zambiri, imodzi si yabwino kuposa ina, koma amachita mosiyana pazochitika zosiyanasiyana. Moyenera, zonse ziwirizi zitha kukhala mbali ndi mbali mu zida za akatswiri opaka.

ZOPITA ZOCHOKERA MMADZI

Utoto wapamadzi umapanga pafupifupi 80 peresenti ya utoto wapakhomo womwe ukugulitsidwa lero malinga ndi bungwe lolangiza ndi kuyesa utoto la Paint Quality Institute. Palibe kukayikira kuti izi ndizofunika kwambiri chifukwa cha chimodzi mwazokopa zazikulu za mankhwala opangidwa ndi madzi, kaya ndi utoto wamkati wa nyumba kapena zotetezera zolemetsa: fungo lochepa.

Pogwira ntchito m'malo opanda mpweya wabwino, kutuluka kwa zosungunulira kumakhala kovuta kwa ogwira ntchito kapena kuwononga thanzi lawo. Pachifukwa ichi, mapulojekiti ambiri monga omwe amaphatikizapo matanki osungira mafuta ndi magalimoto oyendetsa sitima zapanjanji amagwiritsa ntchito zokutira zotengera madzi. Izi zimachepetsanso kuchuluka kwa zinthu zoyaka zomwe zimamanga pamalo otsekeka. Komabe, izi sizikutanthauza kuti kugwiritsa ntchito zokutira zokhala ndi madzi kumalepheretsa kufunikira kwakeOSHA idavomereza njira zotetezera danga.

Kutsata chilengedwe ndi chifukwa china chodziwika chosankha kugwiritsa ntchito zokutira zokhala ndi madzi. Zosungunulira zambiri zimasanduka nthunzi kukhala zinthu zomwe zimadziwika kuti volatile organic compounds, kapena ma VOC. Maboma adziko, maboma ndi am'deralo nthawi zambiri amawongolera ma VOC pochepetsa kuchuluka kwa mabizinesi omwe amaloledwa kutulutsa munthawi yake. TheEPA imakhazikitsa malamulo adzikokwa ma VOC, koma mayiko ena akhwimitsa ziletso mopitilira apo, zomwe zikufunika kuyesetsa kuti achepetse kutulutsa kwawo.

Zovala zokhala ndi madzi sizikhala ndi zosungunulira ziro, komabe. Zambiri zili ndi zomwe zimatchedwa co-solvents, zosungunulira zomwe zimapezeka m'magulu otsika ndipo zimatanthawuza kuthandiza kukankhira madzi ena onse kuchoka mu zokutira pamene akuuma. Koma popeza zokutira zokhala ndi madzi zilibe ayi, kapena zosungunulira zocheperako, ndi njira yabwino yochepetsera kutulutsa kwa VOC mubizinesi. Kwa makampani ena, izi zingatanthauze kuwononga ndalama zochepa pa upangiri wotsatira chilengedwe. Kapena aletseni kuti asamalipire chindapusa chopitilira ma VOC.

ZOPHUNZITSIRA ZOTHANDIZA

Utoto wopangidwa ndi zosungunulira umapangidwa ndi zinthu zosungunulira zomwe zimapangidwira kuti zisungunuke pogwiritsa ntchito mankhwala omwe ali ndi oxygen. Kawirikawiri, kusuntha mpweya wozungulira zosungunulira zochokera ku zosungunulira kumathandizira kufulumira, kuchepetsa nthawi yowuma.

Zovala izi zimakhala ndi mwayi umodzi waukulu kuposa zokutira zokhala ndi madzi. Satengeka mosavuta ndi chilengedwe monga kutentha ndi chinyezi panthawi yochiritsa. Chinyezi chingalepheretse kuti madzi omwe ali m'madzi opaka madzi asamasefuke, zomwe zimawapangitsa kukhala osatheka kumadera ena.

Zovala zokhala ndi madzi zimaperekanso zovuta pagawo lokonzekera pamwamba pa ntchito yopaka. Madzi, ngakhale amalonjeza zosungunulira nthawi zina, ndi gawo lofunikira kwambiri pakupanga dzimbiri, chifukwa chonse chamakampani opanga zokutira zamakampani poyambira. Ngati madzi akhudzana ndi gawo lapansi asanapakapaka utoto, dzimbiri lingayambe kuchitika. Pofuna kuonetsetsa kuti izi sizili choncho, zokutira zokhala ndi madzi ziyenera kupangidwa kuti madzi onse atuluke kudzera mufilimu yapamwamba isanayambe kuwononga. Izi sizikuganiziridwa ndi zokutira zosungunulira.

Chifukwa chake, mwachidule, ngakhale zokutira zokhala ndi madzi zitha kukhala njira yabwino pantchito zokhala ndi malo ocheperako ndikugwiritsa ntchito zokutira mosalekeza, zilibe zofooka zawo. Ntchito zotseguka, zonyowa, monga zomwe zimapezeka nthawi zambiri mumapulojekiti obwezeretsanso, zitha kupindulabe ndi zokutira zoyenera. Ngati mukufuna kukambirana zamtundu wanji wazinthu zomwe zingakhale zabwino kwambiri pantchito yanu, tikufuna kumva kuchokera kwa inu.Lumikizanani ndi mit-ivy industry Coatingslero. Kapena, ngati mukufuna kuyang'ana mzere wathu wazinthu zonse kaye, tsitsani kalozera wathu wazogulitsa pansipa.
