Izembozo ezisekelwe emanzini uma kuqhathaniswa nezembozo ezisekelwe ku-solvent

Ama-coatings avame ukuthatha igama lawo ku-binder, noma i-resin, lapho enziwa khona. Ama-epoxies, ama-alkyd nama-urethane konke kuyizibonelo zama-resin anikeza i-coat igama lawo. Kodwa lezi akuzona zodwa izingxenye ezakha i-coat. Ngaphezu kwezithasiselo, ezinganikeza i-coat izakhiwo ezithile zokusebenza, kanye nemibala enikeza umbala, ama-coatings aqukethe nesakhi esincibilikisa konke kube uketshezi ukuze kube lula ukuyisebenzisa.

Le khemikhali encibilikisa uketshezi ivame ukuba sesimweni samanzi noma esinye isinyibilikisi samakhemikhali. Ngakho-ke amagama athi “esekelwe emanzini” kanye “esekelwe esinyibilikisi”. Uhlobo luni lomkhiqizo olufanele lo msebenzi luzoncika ezimweni. Ngokuvamile, olunye alungcono kunolunye, kodwa lusebenza ngendlela ehlukile ezimweni ezahlukene. Okungcono kakhulu, zombili izinketho zizoba khona eceleni kwezikhali zochwepheshe be-coating.

IZIMBOZO EZISEKELWE EMANZINI

Upende osekelwe emanzini wakha cishe amaphesenti angama-80 opende wasekhaya othengiswa namuhla ngokusho kwe-Paint Quality Institute, inhlangano eyeluleka futhi ehlola upende. Akungabazeki ukuthi lokhu kungenxa yesinye sezinto ezikhangayo eziyinhloko zemikhiqizo esekelwe emanzini, kungakhathaliseki ukuthi upende wangaphakathi endlini noma upende ovikelayo osindayo: amaphunga ambalwa.

Uma usebenza ezindaweni ezivalekile noma ezingenawo umoya ohlanzekile, ukuhwamuka kwezinyibilikisi kungaba yinto engakhululekile kubasebenzi noma kube yingozi empilweni yabo. Ngenxa yalesi sizathu, amaphrojekthi amaningi afana nalawo ahilela amathangi okugcina uphethiloli kanye nezinqola zamathangi ezitimela asebenzisa izembozo ezisekelwe emanzini. Lokhu kunciphisa nokugcwala kwezinto ezivuthayo ezinqwabelana endaweni evalekile. Nokho, lokho akusho ukuthi ukusetshenziswa kwezimbozo ezisekelwe emanzini kuqeda isidingo sokubaIzinyathelo zokuphepha zesikhala esivalekile ezivunyiwe yi-OSHA.

Ukuthobela imvelo kungenye isizathu esivamile sokukhetha ukusebenzisa isembozo esisekelwe emanzini. Izinyibilikisi eziningi ziyahwamuka zibe yilokho okwaziwa ngokuthi ama-volatible organic compounds, noma ama-VOC. Ohulumeni bezwe, bezifundazwe kanye nabendawo bavame ukulawula ama-VOC ngokukhawulela ukuthi amabhizinisi avunyelwe ukukhipha malini esikhathini esithile.I-EPA ibeka imithetho kazwelonkekuma-VOC, kodwa amanye amazwe aqinise imikhawulo ngisho nangaphezulu, okudinga imizamo ehlangene yokunciphisa ukukhishwa kwawo komoya.

Nokho, izembozo ezisekelwe emanzini azinazo ngempela izinyibilikisi ezingenalutho. Eziningi ziqukethe lokho okubizwa ngokuthi izinyibilikisi ezihlangene, izinyibilikisi ezikhona ngamanani aphansi futhi zenzelwe ukusiza ukususa amanye amanzi asele embekweni njengoba yoma. Kodwa njengoba izembozo ezisekelwe emanzini zingenazo, noma zincane kakhulu izinyibilikisi, ziyindlela enhle yokwehlisa umkhiqizo we-VOC webhizinisi. Kwezinye izinkampani, lokhu kungasho ukuchitha imali encane ekwelulekeni kokuthobela imithetho yezemvelo. Noma ukuzivimbela ekukhokheni izinhlawulo ezinkulu zokudlula izilinganiso ze-VOC.

IZIMBOZO EZISEKELWE KU-SOLVENT

Amapende asekelwe ku-solvent akhiwe ngezinto ezincibilikisa uketshezi ezenzelwe ukuhwamuka ngokusabela kwamakhemikhali nomoya-mpilo. Ngokuvamile, umoya ohambayo ozungeze ungqimba olusekelwe ku-solvent uzosiza ukusheshisa ukusabela, kuncishiswe izikhathi zokomisa.

Lezi zingubo zokugqoka zinenzuzo eyodwa enkulu kunezingubo ezisekelwe emanzini. Azithinteki kakhulu ezimweni zemvelo ezifana nokushisa nomswakama ngesikhathi sokwelashwa. Umswakama empeleni ungavimbela amanzi afakwe emanzini ukuthi angahwamuki, okwenza angasebenzi kwezinye izimo zezulu.

Izembozo ezisekelwe emanzini nazo ziletha inselele esigabeni sokulungiselela ubuso bomsebenzi wokumboza. Amanzi, yize ethatha indawo yezembozo ezithembisayo kwezinye izimo, nawo ayingxenye ebalulekile yenqubo yokugqwala, okuyisizathu esiphelele semboni yezembozo zezimboni kwasekuqaleni. Uma amanzi ethintana nesisekelo ngaphambi kokuba kufakwe isembozo, kungase kuqale ukugqwala kwamabala. Ukuze kuqinisekiswe ukuthi lokhu akunjalo, izembozo ezisekelwe emanzini kumele zenziwe ngendlela yokuthi wonke amanzi adonswe ngefilimu ebusweni ngaphambi kokuba kwenzeke ukugqwala. Lokhu akuyona into okufanele icatshangelwe ngezembozo ezisekelwe ku-solvent.

Ngakho-ke, ngamafuphi, yize ukugqoka okusekelwe emanzini kungaba yindlela enhle yemisebenzi ehilela izikhala ezivalekile kanye nokusetshenziswa kokugqoka okuqhubekayo, akuzona ezingenazo izindawo ezibuthakathaka. Imisebenzi ezimweni ezivulekile nezinomswakama, njengaleyo evame ukutholakala kumaphrojekthi okuvuselela ingqalasizinda, isengazuza ekugqokeni okulungile. Uma ungathanda ukuxoxa ngokuthi hlobo luni lomkhiqizo olungaba ngcono kakhulu kuphrojekthi yakho, singathanda ukuzwa kuwe.Xhumana ne-mit-ivy industry Coatingsnamuhla. Noma, uma ufuna ukubheka umugqa wethu ogcwele womkhiqizo kuqala, landa ikhathalogi yethu yomkhiqizo ngezansi.
