Phenomenon: lub txheej tsis lo rau lub substrate
Vim li cas 1: Qhov saum npoo ntawm cov ntawv luam tawm ua ntej "crystallized".
Tshuaj: Cov txheej txheem luam ntawv yuav tsum xub xav txog lub rooj sib tw cov txheej txheem glazing, hloov cov txheej txheem los yog kev tsim cov vuas tshwj xeeb.
Ua Ntej 2: Cov ntaub ntawv pov thawj ntawm cov ntawv luam tawm tsis haum.
Kua: Cov cwj mem xoom xaim nws.
Vim li cas 3: UV varnish tsis phim qhov nro qhov nrawm ntawm cov ntawv luam, thiab qhov adhesion tsis txaus.
Tov: pre-kho qhov saum npoo ntawm cov khoom.
Cause 4: Cov ntaub ntawv photocuring tsis haum.
Tshuaj: Xyuas qhov ua rau thiab kho kom zoo.
Cov hauv qab no yuav tsum raug xam tias thaum xaiv UV kho:
(1) Cov duab spectrum ntawm tus yees duab duab yog sib luag kom ntau li ntau tau nrog cov zis spectrum ntawm lub teeb ci, kom lub zog hluav taws xob ntawm lub teeb ci yuav siv tau los ntawm lub siab tshaj plaws.
(2) Qhov kev siv yuav tsum tsim nyog, lub teeb muaj zog dhau lawm, cov dawb radicals yog tsim los ceev dhau, thiab qhov siab tshaj qhov siab ua rau ua rau qhov nce ntawm cov tshuaj tiv thaiv, uas muaj kev phom sij rau qhov kev sib txuam ntawm kev sib txuam; yog tias lub zog tsis dhau, cov radicals yog tsim dhau qeeb qeeb.
(3) Yuav tsum muaj lub voj voos luaj kom thiaj li tau teeb pom kev.
(4) Vim tias nws ua rau cov huab cua nyob rau hauv cov huab cua nyob hauv lub teeb ntawm lub teeb duab ultraviolet, cov cuab yeej qhov cua yuav tsum tau muab rau ntawm qhov chaw. Kev ntsuas tau meej ntawm UV zog metabolism yuav muab tau cov ntaub ntawv tsim nyog los txiav txim siab thiab tswj cov kev mob siab rau kev kho tau zoo. Kev ntsuas feem ntau yog ntsuas hluav taws xob. Vim tias lub tshuab ntsuas radiometer muab cov ntaub ntawv, muaj peev txheej ua tau tiag. Tom qab pib txhua txhua hnub, tus neeg teb xov tooj xub tshwm rau UV qhov system nrog lub tshuab ntsuas radiometer thiab sau cov ntaub ntawv los saib seb nws yog nyob rau hauv qhov ntau ntawm qhov yuav tsum tau ua.
(5) Ua tib zoo saib xyuas UV lub teeb shielding cuab yeej kom paub tseeb tias tsis pub dhau UV lub teeb txau thaum ua kom ntseeg tau tias cov pa yuav ntws mus rau hauv UV tua kab mob. Cov cua lim kom tsawg yuav tsum ceev kom huv thiab tsis muaj hmoov av thiab khib nyiab ntawm nws qhov chaw. Yog hais tias siv phom quartz yog siv hauv UV txheej txheem, qhov phaj quartz yuav tsum tau muab coj los xyuas kom paub tseeb tias kev kis tus kab mob UV yog qhov tseem siv tau.
Vim li cas 5: UV luam ntawv thiab UV tsis tsuas yog cov ntim txheej los yog cov coatings yuav tsum tsis txhob tuab heev, txwv tsis pub UV phom thiab UV varnishes yuav tsis zoo rau ntawm cov substrate.
Tov: Raws li qhov tseeb qhov teeb meem, cov khoom siv, kev tswj kom zoo thiab tus neeg teb xov tooj txiav txim siab qhov txheej thickness.
Ua Ntej 6: Qhov kub ntawm lub substrate tsawg tsawg thiab qhov ua kom qeeb qeeb.
Tshuaj: UV varnish yuav tsum yog 50 ~ 60 thaum kis tau los ntawm UV teeb irradiation, vim UV varnish kho tau sai ntawm qhov kub thiab muaj zog adhesion tom qab tua.
Vim li cas 7: Qhov saum npoo ntawm cov khoom uas tsis yog-absorbent tsis corrugated txaus.
Tshuaj: Feem ntau, qhov nro yuav tsum yog 3.8 x 10N los yog ntau dua thiaj li yuav tau txais kev nplua zoo ntawm tus cwj mem.
Nco ntsoov thaum siv kev kho mob corona:
(1) Ib txoj kev kho mob zoo ntawm corona yuav muab tau thaum qhov sib txawv ntawm electrode yog li ntawm 1 hli.
(2) Qhov ntau ntawm cov zis muaj tam sim no muaj kev cuam tshuam zoo rau txoj kev kho mob ntawm corona. Cov zis tam sim no tsis tshua muaj tsawg, thiab cov kev kho mob ntawm corona tsis zoo; tam sim no tso zis ntau zuj zus, thiab cov kev kho mob ntawm corona kho tau zoo.
(3) Ua kom sov siab, kev ceev cov tshuaj tiv thaiv yog nce, cov tshuaj tiv thaiv zoo dua tuaj, kev kho mob zoo dua, tab sis qhov kub tsis siab dhau lawm, txwv tsis pub lub zog tshiab txheej txheem yuav tsim, thiab lub zog yuav poob. ,
(4) Cov av ntawm huab cua yog loj, thiab qhov kev kho mob zoo dua qub, uas yog vim lub nqus dej ntawm cov pa dej hauv cov pa.
