Zovala za UV zokhala ndi madzi - kuphatikiza mtundu wapamwamba kwambiri wazinthu zomwe zimakhudzidwa ndi chilengedwe

Ndi chidwi chowonjezereka pa mayankho okhazikika m'zaka zaposachedwa, tikuwona kufunikira kokulirapo kwa midadada yomangira yokhazikika komanso makina otengera madzi, kusiyana ndi zosungunulira. Kuchiritsa kwa UV ndiukadaulo wothandiza kwambiri womwe unapangidwa zaka makumi angapo zapitazo. Kuphatikiza mapindu ochiritsa mwachangu, machiritso apamwamba kwambiri a UV ndiukadaulo wamakina otengera madzi, ndizotheka kupeza mayiko awiri okhazikika.

Kuchulukitsa kwaukadaulo pakukula kokhazikika
Kukula kwa mliriwu mchaka cha 2020, kusintha kwambiri momwe timakhalira ndikuchita bizinesi, kwakhudzanso kuyang'ana kwambiri zopereka zokhazikika mumakampani opanga mankhwala. Kudzipereka kwatsopano kumapangidwa pazandale zapamwamba m'makontinenti angapo, mabizinesi amakakamizika kuwunikanso njira zawo ndikudzipereka kokhazikika kumawunikidwa mpaka mwatsatanetsatane. Ndipo zili mwatsatanetsatane mayankho omwe angapezeke amomwe matekinoloje angathandizire kukwaniritsa zosowa za anthu ndi mabizinesi m'njira yokhazikika. Momwe matekinoloje angagwiritsire ntchito ndikuphatikizidwa m'njira zatsopano, mwachitsanzo kuphatikiza kwaukadaulo wa UV ndi machitidwe otengera madzi.

Kukankhira kwachilengedwe kwaukadaulo wakuchiritsa kwa UV
Ukadaulo wamachiritso a UV udapangidwa kale mu 1960s pogwiritsa ntchito mankhwala okhala ndi unsaturations kuti achize ndi kuwala kwa UV kapena Electron Beams (EB). Kuphatikizana komwe kumadziwika kuti kuchiritsa ma radiation, mwayi wawukulu unali kuchiritsa pompopompo komanso zida zabwino zokutira. M'zaka za m'ma 80s luso linapangidwa ndikuyamba kugwiritsidwa ntchito pamalonda. Pamene chidziŵitso cha zosungunulira’ chisonkhezero cha chilengedwe chinawonjezereka, momwemonso kutchuka kwa machiritso a radiation monga njira yochepetsera unyinji wa zosungunulira zogwiritsiridwa ntchito. Mchitidwewu sunachedwe ndipo kuwonjezeka kwa kutengera ndi mtundu wa ntchito kwapitilira kuyambira pamenepo, komanso kufunikira kofanana ndi magwiridwe antchito ndi kukhazikika.

Kuchoka ku zosungunulira
Ngakhale kuti UV kuchiza palokha ndi luso zisathe, ntchito zina amafunabe ntchito zosungunulira kapena monomers (ndi chiopsezo kusamuka) kuchepetsa mamasukidwe akayendedwe kwa zotsatira zokhutiritsa pamene ntchito ❖ kuyanika kapena inki. Posachedwapa, lingaliro linatuluka lophatikiza ukadaulo wa UV ndiukadaulo wina wokhazikika: machitidwe opangira madzi. Machitidwewa nthawi zambiri amakhala amtundu wosungunuka m'madzi (mwina kudzera m'madzi osungunuka kapena kusakanikirana kosakanikirana ndi madzi) kapena amtundu wa PUD (polyurethane dispersion) pomwe madontho a gawo losagwirizana amamwazikana m'madzi pogwiritsa ntchito wobalalitsa.

Pamwamba pa matabwa
Poyamba zokutira za UV zokhala ndi madzi zakhala zikugwiritsidwa ntchito makamaka ndi makampani opaka matabwa. Apa zinali zosavuta kuwona ubwino wophatikiza phindu kuchokera ku mlingo waukulu wa kupanga (poyerekeza ndi osakhala UV) ndi kukana kwa mankhwala ndi VOC otsika. Zofunikira mu zokutira pansi ndi mipando. Komabe, posachedwapa ntchito zina zayamba kupeza mphamvu ya UV yochokera kumadzi. Makina osindikizira a digito a UV (inkjet ink) amatha kupindula ndi ubwino wamadzi onse (otsika kukhuthala ndi kutsika kwa VOC) komanso ma inki ochiritsa a UV (kuchiritsa mwachangu, kusamvana bwino komanso kukana mankhwala). Chitukuko chikupita patsogolo mwachangu ndipo ndizotheka kuti mapulogalamu ena ambiri posachedwa awunika mwayi wogwiritsa ntchito machiritso a UV amadzi.

Zopaka za UV zochokera m'madzi kulikonse?
Tonse tikudziwa kuti dziko lathu lapansi likukumana ndi zovuta zina m'tsogolomu. Ndi kuchuluka kwa anthu komanso kuchuluka kwa moyo, kugwiritsa ntchito komanso kasamalidwe ka zinthu kumakhala kofunika kwambiri kuposa kale. Kuchiritsa kwa UV sikungakhale yankho ku zovuta zonsezi koma zitha kukhala gawo limodzi lachidule ngati ukadaulo wogwiritsa ntchito mphamvu ndi zida. Tekinoloje zachikhalidwe zosungunulira zimafunikira mphamvu zamagetsi zowumitsa, komanso kutulutsidwa kwa VOC. Kuchiritsa kwa UV kutha kuchitidwa pogwiritsa ntchito magetsi otsika amphamvu a LED a inki ndi zokutira zomwe zilibe zosungunulira kapena, monga taphunzirira m'nkhaniyi, kugwiritsa ntchito madzi okha ngati zosungunulira. Kusankha matekinoloje okhazikika komanso njira zina zimakuthandizani kuti musamangoteteza khitchini yanu kapena shelufu yamabuku ndi zokutira zowoneka bwino, komanso kuteteza ndikuzindikira zoperewera za dziko lathu lapansi.
