1. Kev Siv Tshuab UV Curing yog dab tsi?
UV Curing Technology yog ib txoj kev siv tshuab uas kho sai sai lossis ziab hauv vib nas this uas siv ultraviolet rau cov resins xws li coatings, adhesives, marking ink thiab photo-resists, thiab lwm yam, ua rau photopolymerization. Nrog rau cov txheej txheem olymerization reaction los ntawm kev ziab cua sov lossis sib tov ob lub kua, feem ntau nws siv sijhawm li ob peb feeb mus rau ob peb teev kom qhuav ib lub resin.
Kwv yees li 40 xyoo dhau los, cov thev naus laus zis no tau siv thawj zaug rau kev ziab cov ntawv luam tawm ntawm cov ntoo plywood rau cov ntaub ntawv tsim kho. Txij thaum ntawd los, nws tau siv rau hauv cov teb tshwj xeeb.
Tsis ntev los no, kev ua tau zoo ntawm UV curable resin tau zoo dua qub. Ntxiv mus, ntau hom UV curable resins tam sim no muaj thiab lawv siv nrog rau kev ua lag luam tab tom loj hlob sai, vim nws muaj txiaj ntsig zoo rau kev txuag hluav taws xob / qhov chaw, txo cov khib nyiab, thiab ua tiav kev tsim khoom siab thiab kev kho mob kub qis.
Ntxiv rau, UV kuj tseem tsim nyog rau kev txhaj tshuaj kho qhov muag vim nws muaj lub zog ceev ceev thiab nws tuaj yeem tsom mus rau qhov tsawg kawg nkaus ntawm qhov chaw, uas pab kom yooj yim tau txais cov khoom pwm siab.
Yeej, vim yog ib tus neeg sawv cev uas tsis yog cov kuab tshuaj, UV curable resin tsis muaj cov kuab tshuaj organic uas ua rau muaj kev cuam tshuam tsis zoo (piv txwv li, pa phem) rau ib puag ncig. Ntxiv mus, vim tias lub zog xav tau rau kev kho yog tsawg dua thiab cov pa roj carbon dioxide tsawg dua, cov thev naus laus zis no txo cov teeb meem ib puag ncig.
2. Cov yam ntxwv ntawm UV Curing
1. Kev kho mob tshwm sim hauv vib nas this
Hauv cov tshuaj kho, monomer (Kua) hloov mus ua polymer (Khoom) hauv ob peb feeb xwb.
2. Kev teb zoo rau ib puag ncig
Vim tias tag nrho cov khoom siv tau kho los ntawm kev siv photopolymerization uas tsis muaj kuab tshuaj, nws zoo heev rau kev ua kom tau raws li cov kev cai thiab kev txiav txim siab ib puag ncig xws li PRTR (Pollutant Release and Transfer Register) Law lossis ISO 14000.
3. Zoo meej rau kev ua haujlwm tsis siv neeg
Cov khoom siv kho tau los ntawm UV yuav tsis kho tau tsuas yog raug lub teeb xwb, thiab tsis zoo li cov khoom siv kho tau los ntawm cua sov, nws yuav tsis kho maj mam thaum lub sijhawm khaws cia. Yog li ntawd, nws lub sijhawm siv tau luv txaus rau nws siv rau hauv cov txheej txheem automation.
4. Kev kho mob kub qis yog ua tau
Vim tias lub sijhawm ua tiav luv luv, nws muaj peev xwm tswj tau qhov kub ntawm qhov khoom uas xav tau. Qhov no yog ib qho ntawm cov laj thawj vim li cas nws thiaj siv rau hauv feem ntau cov khoom siv hluav taws xob uas rhiab heev rau cua sov.
5. Haum rau txhua hom kev siv vim muaj ntau yam khoom siv
Cov ntaub ntawv no muaj qhov tawv thiab ci ntsa iab. Tsis tas li ntawd xwb, lawv muaj ntau xim, yog li ntawd siv tau rau ntau yam.
3. Lub Ntsiab Cai ntawm UV Curing Technology
Cov txheej txheem ntawm kev hloov cov monomer (kua) mus rau hauv cov polymer (khoom) nrog kev pab los ntawm UV hu ua UV Curing E thiab cov khoom siv organic synthetic uas yuav tsum tau kho hu ua UV Curable Resin E.
UV Curable Resin yog ib qho tshuaj uas muaj:
(a) monomer, (b) oligomer, (c) photopolymerization initiator thiab (d) ntau yam additives (stabilizers, fillers, pigments, thiab lwm yam).
(a) Monomer yog ib yam khoom siv organic uas tau polymerized thiab hloov mus ua cov molecule loj dua ntawm polymer los ua yas. (b) Oligomer yog ib yam khoom siv uas twb tau ua rau monomers. Ib yam li monomer, oligomer yog polymerized thiab hloov mus ua cov molecule loj los ua yas. Monomer lossis oligomer tsis yooj yim tsim cov tshuaj polymerization, yog li ntawd lawv tau ua ke nrog lub photopolymerization initiator los pib cov tshuaj. (c) Lub photopolymerization initiator raug txhawb los ntawm kev nqus ntawm lub teeb thiab thaum cov tshuaj, xws li cov hauv qab no, tshwm sim:
(b) (1) Kev tawg ua tej daim me me, (2) Kev rho tawm cov hydrogen, thiab (3) Kev hloov pauv ntawm cov electron.
(c) Los ntawm qhov kev tshuaj tiv thaiv no, cov tshuaj xws li cov tshuaj radical, hydrogen ions, thiab lwm yam, uas pib qhov kev tshuaj tiv thaiv tau tsim. Cov tshuaj radical tsim, hydrogen ions, thiab lwm yam, tawm tsam oligomer lossis monomer molecules, thiab qhov kev sib txuas polymerization lossis crosslinking peb-seem tshwm sim. Vim yog qhov kev tshuaj tiv thaiv no, yog tias cov tshuaj molecules uas muaj qhov loj dua qhov loj me tau teev tseg, cov tshuaj molecules uas raug UV hloov ntawm kua mus rau khoom khov. (d) Ntau yam khoom ntxiv (stabilizer, filler, pigment, thiab lwm yam) tau ntxiv rau cov khoom siv UV kho tau raws li qhov xav tau, rau
(d) muab nws ruaj khov, muaj zog, thiab lwm yam.
(e) Cov kua nplaum uas kho tau UV, uas ntws tau yooj yim, feem ntau kho tau los ntawm cov kauj ruam hauv qab no:
(f) (1) Cov tshuaj pib ua kom pom kev zoo (Photopolymerization initiators) nqus tau UV.
(g) (2) Cov photopolymerization initiators uas tau nqus UV yog excited.
(h) (3) Cov neeg pib ua kom muaj photopolymerization ua haujlwm tau teb nrog cov khoom siv resin xws li oligomer, monomer, thiab lwm yam, los ntawm kev rhuav tshem.
(i) (4) Ntxiv mus, cov khoom no ua rau muaj kev cuam tshuam nrog cov khoom siv resin thiab ua rau muaj kev sib txuas lus. Tom qab ntawd, qhov kev sib txuas lus peb-seem txuas ntxiv mus, qhov hnyav ntawm cov molecular nce ntxiv thiab cov resin tau kho.
(j) 4. UV yog dab tsi?
(k) UV yog ib nthwv dej hluav taws xob uas muaj qhov ntev ntawm 100 txog 380 nm, ntev dua li ntawm X-rays tab sis luv dua li ntawm cov duab pom.
(l) UV raug muab faib ua peb pawg raws li nws qhov wavelength:
(m) UV-A (315-380nm)
(n) UV-B (280-315nm)
(o) UV-C (100-280nm)
(p) Thaum siv UV los kho cov resin, cov chav ntsuas hauv qab no yog siv los ntsuas qhov ntau ntawm UV hluav taws xob:
(q) - Qhov muaj zog ntawm kev tawg (mW/cm2)
(r) Qhov muaj zog ntawm kev tawg hluav taws xob rau ib cheeb tsam
(s) - Kev raug UV (mJ/ cm2)
(t) Lub zog irradiation ib cheeb tsam thiab tag nrho cov photons kom ncav cuag qhov chaw. Cov khoom ntawm qhov muaj zog irradiation thiab lub sijhawm.
(u) - Kev sib raug zoo ntawm kev raug UV thiab qhov muaj zog ntawm kev ci ntsa iab
(v) E=I x T
(w) E=Kev raug UV (mJ/cm2)
(x) Kuv = Qhov Muaj Zog (mW/cm2)
(y) T = Lub sijhawm irradiation (s)
(z) Vim tias qhov kev raug UV uas xav tau rau kev kho kom zoo nyob ntawm cov khoom siv, lub sijhawm irradiation uas xav tau tuaj yeem tau txais los ntawm kev siv cov mis saum toj no yog tias koj paub qhov muaj zog ntawm UV irradiation.
