INyob rau hauv xyoo tas los no, UV txheej tau txais kev saib xyuas ntau dua thoob plaws hauv kev lag luam xws li kev ntim khoom mus rau cov khoom siv hluav taws xob. Paub txog nws lub peev xwm los xa cov tiav ci ntsa iab thiab kev tiv thaiv ntev, cov thev naus laus zis no tau raug qhuas tias ua haujlwm tau zoo thiab zoo rau ib puag ncig. Tab sis nws ua haujlwm li cas tiag?
Kev txheej UV siv cov txheej txheem hu ua ultraviolet curing. Lub txheej nws tus kheej yog cov kua sib xyaw uas muaj oligomers, monomers, thiab photo-initiators. Thaum siv rau ntawm qhov chaw, cov khoom siv coated raug rau lub teeb ultraviolet. Cov photo-initiators nqus lub zog teeb, tsim cov hom tshuaj reactive xws li cov free radicals. Cov molecules reactive no sai sai ua rau polymerization, hloov cov kua txheej mus rau hauv ib daim zaj duab xis khov kho, crosslinked hauv ob peb feeb.
Cov kws tshaj lij hauv kev lag luam hais tias cov txheej txheem kho sai no tsis yog tsuas yog txo lub sijhawm tsim khoom xwb tab sis kuj tshem tawm qhov xav tau kev ziab los ntawm cua sov, ua rau UV txheej txuag hluav taws xob ntau dua. Cov zaj duab xis kho no muab kev tiv thaiv khawb zoo heev, ua kom ruaj khov tshuaj lom neeg, thiab zoo nkauj dua, uas piav qhia nws siv dav hauv kev ua tiav rooj tog, cov ntaub ntawv luam tawm, kev kho tsheb sab hauv, thiab txawm tias cov khoom siv hluav taws xob siab.
Lwm qhov zoo tseem ceeb, cov kws tshuaj ntsuam kev lag luam sau tseg, yog qhov profile ib puag ncig ntawm UV coatings. Tsis zoo li cov tshuaj pleev ib txwm muaj uas tso tawm cov organic compounds (VOCs), ntau cov qauv UV tau tsim los kom yuav luag tsis muaj VOC. Qhov no txo cov pa phem thiab kev phom sij ntawm chaw ua haujlwm, ua raws li cov qauv ib puag ncig thoob ntiaj teb nruj dua.
Kev nce qib hauv daim teb no kuj ua rau kev siv cov txheej UV dav dua. Cov kev tsim kho tshiab tsis ntev los no suav nrog cov txheej UV-curable rau cov yeeb yaj kiab ntim khoom, cov txheej uas tiv taus siab rau cov khoom siv kho mob, thiab txawm tias cov qauv biocompatible rau kev siv hauv kev kho mob. Cov kws tshawb fawb kuj tab tom sim nrog cov kab ke hybrid UV uas sib xyaw ua ke kev kho hluav taws xob nrog nanotechnology los txhim kho kev ua haujlwm thaiv thiab txuas lub neej khoom.
Thaum kev ruaj khov ua qhov tseem ceeb hauv kev tsim khoom, cov kws tshaj lij kwv yees tias cov thev naus laus zis UV txheej yuav ua lub luag haujlwm tseem ceeb zuj zus. Nrog rau kev thov thoob ntiaj teb rau cov khoom siv zoo rau ib puag ncig thiab kev ua tau zoo siab nce ntxiv, UV txheej yuav tsum teeb tsa cov qauv tshiab rau kev ua haujlwm zoo, kev ruaj khov, thiab kev tsim qauv, rov tsim cov qauv thoob plaws ntau yam lag luam.
