Zophimba zoyendetsedwa ndi madzindi mtundu waukulu kwambiri wa ukadaulo wopaka utoto womwe umagwiritsidwa ntchito padziko lonse lapansi ndipo akuyembekezeka kupitiliza kukula ngati peresenti ya msika wonse wopaka utoto. Pofika chaka cha 2022,kukula kwa msika wapadziko lonse lapansiKuchuluka kwa zophimba zomwe zimapakidwa m'madzi kukuyembekezeka kupitirira $146 biliyoni USD. Kukula kwakukulu kumachitika chifukwa cha kuchuluka kwa ntchito m'misika yomanga ndi yamagalimoto ndima acrylickukhala mtundu umodzi waukulu kwambiri wa makina opangidwa ndi utomoni wa m'madzi omwe akuyimira oposa 80% ya msika wonse wopangidwa ndi madzi.

Iyi ndi Athena.MIT-IVY INDUSTRY yomwe imagwira ntchito makamaka ndi utoto wa mafakitale wopangidwa ndi madzi, ndikudziwa kuti mukufuna zinthu zabwino, zotsika mtengo komanso zothandizira zaukadaulo, tili ndi satifiketi ya ISO, makamaka mndandanda wazinthu zomwe zili ndi mtengo wake. Timakhulupirira kwambiri zamtundu wapamwamba,

Ndipo makasitomala athu akukhutira. Ngati mukufuna kufunsa, chonde nditumizireni uthenga. ️ Lumikizanani nafe:

Mphamvu zoyendetsaKugwiritsa ntchito kwambiri zophimba zamadzi ndi monga:

• VOC Yotsika
• Kuyeretsa kosavuta nthawi zambiri
• Kuchepa kwa ngozi ya moto
• Mtengo wotsika wa inshuwaransi
• Kugwiritsa ntchito mphamvu zochepa pazokutira zophikidwachifukwa chosowa mpweya wochepa wopaka zodzoladzola mu uvuni
• Kufunika kwa kuchepa kwa milingo yamafuta-zinthu zopangidwa ndi zinthu.

Monga nkhani ya Prospector ya mu Meyi, 2014 paKuyenda, Kusanja ndi Kuwongolera Kukhuthala mu Zophimba Zochokera M'madzizikusonyeza kuti, magulu awiri akuluakulu a zokutira zogwiritsidwa ntchito m'madzi ndi awa:chochepetsedwa madzindilatex, ndipo zophimba zambiri zophikidwa zili mgulu loyamba ndipo zophimba zambiri zomangidwa zili mgulu lachiwiri. Mawuwachochepetsedwa madziamagwiritsidwa ntchito pa ma resin opangidwa mu solvent ndi kuchepetsedwa m'madzi kuti apange kufalikira kwa utomoni m'madzi.LatexKoma ma resin amakonzedwa ndi emulsion polymerization m'madzi.

Zoyipa zogwiritsa ntchito zokutira m'madzi ndi izi:

• Kudalira kwambiri kuchuluka kwa nthunzi pa chinyezi
• Kutentha kwambiri kwa madzi kumafuna 2260 J/g pa madzi ndipo mwachitsanzo 373 J/g yokha pa madzi.2-butoxyethanol, chinthu chomwe chimagwiritsidwa ntchito kwambiricosolvent
• Chophimba chochepetsera kukhuthala kopanda mzere cha zokutira pogwiritsa ntchito ma resini ochepetsa madzi
• Kudalira kwambiri kwa kayendedwe ka madzi ndi mawonekedwe ake pa chinyezi
• Kuthamanga kwakukulu kwa madzi pamwamba (kunyowa pang'ono) kumafuna kuwonjezerazinthu zopangira ma surfactantszomwe nthawi zambiri zimalepheretsa kukana chinyezi
• Zophimba zoyendetsedwa ndi madzi zimawononga kwambiri kuposa zophimba zosungunuka ndipo motero zimafuna zotengera zokhala ndi mipanda, pulasitiki kapena chitsulo chosapanga dzimbiri kuti zipewe dzimbiri
• Zophimba zogwiritsidwa ntchito m'madzi zimakhala zosavuta kuonekera m'mafakitale ophikidwa pamene filimu imayamba kupangika madzi asanatuluke mu filimuyo (onani Gome I)

Komabe, kupita patsogolo kwa sayansi ya zinthu zakuthupi kuphatikizapo zatsopano mu utomoni wa chemistry, ma surfactants,zinthu zonyowetsandizinthu zoyendetsera kayendedwe ka madzizithandiza kuti zinthu zophimba m'madzi zipitirire kukula.

Chithunzi Choyamba chikuyimira magawo osiyanasiyana pakuuma kwa utoto wopangidwa ndi latex. Gawo loyamba limakhudza kuuma kwa madzi. Gawo lachiwiri limaphatikizapo kuuma kwa madzi ndi cosolvent mpaka pomwe tinthu ta latex timakhudza ndikuyamba kugwirizana kuti tipange filimu yomwe imauma pang'ono.

Gawo lomaliza limaphatikizapo kupitiriza kuphatikizika ndi kuchira (mu dongosolo lolumikizidwa) kuti apange filimu yowuma komanso yolimba yopaka utoto.

Chimodzi mwa zinthu zofunika kwambiri pakugwiritsa ntchito zophimba za m'madzi ndi kuchuluka kwa ntchito yomwe chinyezi komanso kutentha zimachita pakugwiritsa ntchito ndi kuchiritsa zophimba izi. Mwachitsanzo, kuti zipereke mawonekedwe ovomerezeka ogwiritsira ntchito, kutentha ndi chinyezi ziyenera kulamulidwa mosamala monga momwe zasonyezedwera pa Chithunzi Chachiwiri. Zotsatira za chinyezi pa zophimba zomwe zili ndi madzi-organic solvent sizinganyalanyazidwe.

Mwachitsanzo, kuchuluka kwa evaporation rate (E) ya madzi pa 0 - 5% RH pa 25°C ndi 0.31, koma pa 100% RH E ndi 0. E ya 2-butoxyethanol, cosolvent yomwe imagwiritsidwa ntchito kwambiri, ndi 0.077. Pa RH yotsika, madzi amasanduka nthunzi mofulumira ndipo motero chiŵerengero cha 2-butoxyethanol ndi madzi chimawonjezeka; zosiyana ndi izi zimachitika pakakhala chinyezi chambiri.

Ngati zophimba zogwiritsidwa ntchito m'madzi zikugwiritsidwa ntchito, ngati chinyezi sichinyalanyazidwa, kusintha kwa mawonekedwe ndi mawonekedwe a ntchito kudzachitika. Mwachitsanzo, ngati kutentha komwe kumagwiritsidwa ntchito chaka chonse ndi 70° – 80° F, kugwiritsa ntchito kouma (kutayika kwa madzi) kudzachititsa miyezi yozizira chifukwa cha chinyezi chochepa makamaka m'nyengo yozizira komanso kuchuluka kwa madzi kudzawoneka m'miyezi yachilimwe (kuchuluka kwa chinyezi). Chitsanzo cha zomwe zimachitika pambuyo pake ndichakuti pafupifupi 65% Relative Humidity/25 °C, chophimba chogwiritsidwa ntchito m'madzi chokhala ndi 10.6% 2-butoxyethanol ya volatiles, kuchuluka kwa madzi ndi 2-butoxyethanol ndi kofanana. Chinyezichi chimatchedwa Critical Relative Humidity.

Chithunzi Chachiwiri Kugwiritsa Ntchito Kudalira kwa Zophimba Zochokera M'madzi pa Chinyezi ndi Kutentha.

Gome Loyamba likuwonetsa kudalira kwakukulu kwa zophimba zoyendetsedwa ndi madzi pakutuluka kwa makulidwe osiyanasiyana a filimu poyerekeza ndi zophimba zobadwa nazo.

Gome I Kukhuthala Kofunikira kwa Mafilimu Opangidwa ndi Ma Micron, Zophimba Zachilengedwe, Wiley-Interscience, 2007, Zeno W. Wicks Jr., Frank N. Jones, S. Peter Pappas, Douglas A. Wicks

Zophimba zoyendetsedwa ndi madzi zimaphatikizapo mitundu yosiyanasiyana ya utomoni mongaacrylic,alkyd,urethane,poliyesitala,epoxy,fluoropolymer, ufa wopangidwa m'madzi komanso mankhwala ochiritsa kuphatikizapoMachiritso a UV,aminoplast, urethane,epoxy-polyamide,okosijenindithermoplastic youma ndi mpweyamitundu. Monga momwe Gome II likusonyezera, kukula kwa tinthu ndi kapangidwe ka tinthu (monga chipolopolo chapakati) zimathandizanso pakupanga filimu yabwino kwambiri ya utoto. Mwachidule, nkhani zapadera zokhudzana ndi kugwiritsa ntchito utoto wopangidwa ndi madzi zikaganiziridwa bwino, zimapereka magwiridwe antchito abwino kwambiri pamitundu yosiyanasiyana.
