Uburyo bwo gukiza UV & EB

Gukiza UV & EB mubisanzwe bisobanura ikoreshwa rya elegitoronike (EB), ultraviolet (UV) cyangwa urumuri rugaragara kugirango polymerize ikomatanya monomers na oligomers kuri substrate. Ibikoresho bya UV & EB birashobora guhindurwa muri wino, gutwikira, gufatisha cyangwa ibindi bicuruzwa. Inzira izwi kandi nk'imishwarara ikiza cyangwa imishwarara kuko UV na EB ni isoko y'ingufu. Inkomoko yingufu za UV cyangwa urumuri rugaragara rusanzwe ni amatara ya mercure yumuvuduko ukabije, amatara ya xenon, LED cyangwa lazeri. EB - bitandukanye na fotone yumucyo, ikunda kwinjizwa cyane cyane hejuru yibikoresho - ifite ubushobozi bwo kwinjira mubintu.
Impamvu eshatu zikomeye zo guhindura tekinoroji ya UV & EB
Kuzigama ingufu no kongera umusaruro: Kubera ko sisitemu nyinshi zidashobora gukemuka kandi bisaba munsi yisegonda imwe yo kwerekana, inyungu yumusaruro irashobora kuba nini ugereranije nubuhanga busanzwe bwo gutwikira. Urubuga rwihuta rwa 1.000 ft / min. birasanzwe kandi ibicuruzwa bihita byitegura kugerageza no koherezwa.

Bikwiranye na Sensitive Substrates: Sisitemu nyinshi ntabwo zirimo amazi cyangwa umusemburo. Mubyongeyeho, inzira itanga igenzura ryuzuye ryubushyuhe bwo gukiza bigatuma biba byiza gukoreshwa kubutaka bwangiza ubushyuhe.

Ibidukikije hamwe n’abakoresha inshuti: Ibigize mubusanzwe bidafite ibisubizo kuburyo ibyuka bihumanya hamwe n’umuriro ntabwo ari impungenge. Sisitemu yo gukiza yoroheje irahujwe nubuhanga hafi ya bwose bwo gusaba kandi bisaba byibuze umwanya. Amatara ya UV arashobora gushyirwaho kumurongo uhari.

UV & EB Ibishobora gukira
Monomers nuburyo bworoshye bwubaka buvamo ibikoresho ngengabuzima. Monomer yoroshye ikomoka kubiryo bya peteroli ni Ethylene. Ihagarariwe na: H2C = CH2. Ikimenyetso "=" hagati yibice byombi cyangwa atome ya karubone byerekana urubuga rudasanzwe cyangwa nkuko abahanga mu bya shimi babivuga, "inkwano ebyiri" cyangwa kutuzura. Nibibuga nkibi bishoboye kubyitwaramo gukora ibikoresho binini cyangwa binini binini byitwa oligomers na polymers.

Polimeri ni itsinda rya benshi (ni ukuvuga poly-) gusubiramo ibice bya monomer imwe. Ijambo oligomer nijambo ryihariye rikoreshwa mugusobanura izo polymers akenshi zishobora kurushaho kwitabwaho kugirango habeho guhuza runini rwa polymers. Imbuga zidahagije kuri oligomers na monomers zonyine ntizishobora gukorerwa reaction cyangwa guhuza.

Kubijyanye no gukiza ibiti bya electron, ingufu nyinshi za electron zikorana na atome yikibanza kidahagije kugirango habeho molekile ikora cyane. Niba UV cyangwa urumuri rugaragara rukoreshwa nkisoko yingufu, fotoinitiator yongewe kumvange. Photinitiator, iyo ihuye numucyo, itanga radical yubuntu cyangwa ibikorwa bitangiza guhuza hagati yimbuga zidahagije.ibigize UV ​​& ude

Oligomers: Muri rusange ibintu byose bisize, wino, ibifata cyangwa binder bihujwe ningufu zumucyo bigenwa cyane cyane na oligomers ikoreshwa mugutegura. Oligomers ni polimeri yuburemere buringaniye ya polymers, inyinshi murizo zishingiye kuri acrylation yuburyo butandukanye. Acrylation itanga kudahaza cyangwa itsinda rya "C = C" kumpera ya oligomer.

Monomers: Monomers ikoreshwa cyane cyane nkimyunyu ngugu kugirango igabanye ububobere bwibikoresho bidafite umutekano kugirango byoroherezwe gukoreshwa. Birashobora kuba imikorere imwe, ikubiyemo itsinda rimwe gusa ryitwara neza cyangwa urubuga rudahagije, cyangwa imikorere myinshi. Uku kudahaza kubafasha kubyitwaramo no kwinjizwa mubintu byakize cyangwa byarangiye, aho guhindagurika mukirere nkuko bisanzwe mubisanzwe. Imikorere myinshi, kubera ko irimo imbuga ebyiri cyangwa nyinshi zidakora, zikora amahuza hagati ya molekile ya oligomer nabandi ba monomers.

Photoinitiators: Iki kintu gikurura urumuri kandi gifite inshingano zo gukora radicals cyangwa ibikorwa byubusa. Ibikorwa bya radicals cyangwa ibikorwa byubusa nubwoko bwingufu nyinshi zitera guhuza hagati yikibanza kidahagije cya monomers, oligomers na polymers. Photoinitiator ntabwo ikenewe kuri sisitemu ya elegitoroniki yakize kuko electron zishobora gutangiza guhuza.

Ibyongeweho: Bikunze kugaragara cyane ni stabilisateur, irinda gelation mububiko no gukira imburagihe bitewe nurwego ruke rwumucyo. Ibara ryamabara, amarangi, defoamers, poroteri ya adhesion, ibikoresho byo guswera, ibikoresho byo guhanagura hamwe nibikoresho bifasha kunyerera ni ingero zindi nyongeramusaruro.
