Kusindikiza kwa UV Ndi Njira Yapadera

Njira yoyeretsera misomali pogwiritsa ntchito UV - njira yowumitsa pogwiritsa ntchito photochemical - idayambitsidwa poyamba ngati njira yowumitsa misomali pogwiritsa ntchito gel yomwe imagwiritsidwa ntchito popanga manicure, koma posachedwapa yagwiritsidwa ntchito ndi makampani osindikizira kumene imagwiritsidwa ntchito kusindikiza chilichonse kuyambira zizindikiro ndi mabulosha mpaka mabotolo a mowa. Njirayi ndi yofanana ndi yosindikizira yachikhalidwe, kusiyana kokha ndi inki zomwe zimagwiritsidwa ntchito ndi njira yowumitsa - ndi zinthu zabwino kwambiri zomwe zimapangidwa.

Mu kusindikiza kwachikhalidwe, ma inki osungunula amagwiritsidwa ntchito; awa amatha kusungunuka ndikutulutsa mankhwala osasunthika achilengedwe (VOCs) omwe ndi owopsa ku chilengedwe. Njirayi imapanganso - ndikugwiritsa ntchito - kutentha ndi fungo lotsagana nalo. Kuphatikiza apo, imafuna ufa wowonjezera wopopera kuti uthandize njira yochepetsera inki ndi kuumitsa, zomwe zingatenge masiku angapo. Ma inkiwo amalowa mu chosindikizira, kotero mitundu imatha kuoneka ngati yatsukidwa ndikuzimiririka. Njira yosindikizira imangokhala makamaka pa mapepala ndi makadi, kotero singagwiritsidwe ntchito pa zipangizo monga pulasitiki, galasi, chitsulo, zojambulazo kapena acrylic monga kusindikiza kwa UV.

Mu kusindikiza kwa UV, magetsi a mercury/quartz kapena LED amagwiritsidwa ntchito poyeretsa m'malo mwa kutentha; kuwala kwa UV kwamphamvu kwambiri komwe kumapangidwa mwapadera kumatsatira kwambiri pamene inki yapadera imagawidwa pa chosindikizira, ndikuuma ikangogwiritsidwa ntchito. Chifukwa inkiyo imasintha kuchoka pa cholimba kapena phala kukhala madzi nthawi yomweyo, palibe mwayi woti isungunuke ndipo motero palibe ma VOC, utsi wapoizoni kapena ozoni omwe amatulutsidwa, zomwe zimapangitsa ukadaulowu kukhala wochezeka kwa chilengedwe popanda kuwononga mpweya.

Inki, guluu kapena chophimbacho chimakhala ndi chisakanizo cha ma monomers amadzimadzi, ma oligomers - ma polima okhala ndi mayunitsi ochepa obwerezabwereza - ndi ma photoinitiators. Panthawi yokonza, kuwala kwamphamvu kwambiri m'mbali ya ultraviolet ya sipekitiramu, yokhala ndi mafunde pakati pa 200 ndi 400 nm, imatengedwa ndi photoinitiator yomwe imadutsa mu chemical reaction - chemical cross linking - ndipo imapangitsa inki, chophimbacho kapena chophimbacho kuuma nthawi yomweyo.

N'zosavuta kuona chifukwa chake kusindikiza kwa UV kwaposa njira zachikhalidwe zoumitsira pogwiritsa ntchito madzi ndi zosungunulira komanso chifukwa chake kukuyembekezeka kupitiliza kutchuka. Sikuti njira iyi imangofulumizitsa kupanga - zomwe zikutanthauza kuti zambiri zimachitika munthawi yochepa - kuchuluka kwa kukana kumachepa chifukwa cha kuchuluka kwa utoto. Madontho a inki onyowa amachotsedwa, kotero palibe kupukuta kapena kufinya, ndipo pamene kuumitsa kumachitika nthawi yomweyo, palibe kusungunuka kwa madzi ndipo chifukwa chake palibe kutayika kwa makulidwe kapena kuchuluka kwa utoto. Tsatanetsatane wabwino ndi wotheka, ndipo mitundu ndi yakuthwa komanso yowala bwino chifukwa palibe kuyamwa kwa njira yosindikizira: kusankha kusindikiza kwa UV m'malo mwa njira zachikhalidwe zosindikizira kungakhale kusiyana pakati pa kupanga chinthu chapamwamba, ndi chinthu chomwe chimamveka ngati chosakwera kwambiri.

Inkiyi ilinso ndi mawonekedwe abwinobwino, kunyezimira bwino, kukanda bwino, kukana mankhwala, zosungunulira ndi kuuma, kusinthasintha bwino ndipo chomaliza chimapindulanso ndi mphamvu yabwino. Ndi cholimba komanso cholimba, ndipo chimapereka kukana kowonjezereka kwa kutha kwa zinthu zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito zizindikiro zakunja. Njirayi ndi yotsika mtengo kwambiri - zinthu zambiri zimatha kusindikizidwa munthawi yochepa, pamtundu wabwino komanso popanda kukanidwa kwambiri. Kusowa kwa ma VOC omwe amatulutsidwa kumatanthauza kuti chilengedwe sichiwonongeka kwambiri ndipo machitidwewa ndi okhazikika.
