UV CURING Technology

1. UV Curing Technology yog dab tsi?

UV Curing Technology yog ib qho cuab yeej ntawm kev kho tam sim lossis ziab hauv vib nas this uas ultraviolet yog siv rau cov resins xws li coatings, adhesives, marking number case thiab photo-resists, thiab lwm yam, ua rau photopolymerization. Nrog rau txoj kev olymerization cov tshuaj tiv thaiv los ntawm kev ziab kom qhuav los yog sib tov ob lub kua, nws feem ntau siv sijhawm li ob peb feeb mus rau ob peb teev kom qhuav cov resin.

Txog 40 xyoo dhau los, cov tshuab no tau siv thawj zaug rau kev ziab cov ntawv luam ntawm plywood rau cov khoom siv hauv tsev. Txij thaum ntawd los, nws tau siv nyob rau hauv tej thaj chaw.

Tsis ntev los no, kev ua tau zoo ntawm UV curable resin tau zoo tuaj. Ntxiv mus, ntau hom UV curable resins tam sim no muaj thiab lawv siv raws li kev lag luam loj hlob sai, vim nws muaj txiaj ntsig zoo ntawm kev txuag hluav taws xob / chaw, txo cov khoom pov tseg, thiab ua tiav cov khoom lag luam siab thiab kev kho cua sov.

Tsis tas li ntawd, UV tseem haum rau Optical molding vim nws muaj lub zog muaj zog thiab nws tuaj yeem tsom rau cov khoom tsawg kawg nkaus, uas tau yooj yim tau txais cov khoom lag luam siab.

Yeej, ua ib tus neeg tsis muaj kuab tshuaj, UV curable resin tsis muaj cov kuab tshuaj organic uas ua rau muaj kev cuam tshuam tsis zoo (xws li huab cua paug) rau ib puag ncig. Tsis tas li ntawd, vim tias lub zog xav tau rau kev kho mob tsawg dua thiab cov pa roj carbon dioxide emission qis dua, cov cuab yeej no txo ​​qhov hnyav ntawm ib puag ncig.

2. Nta ntawm UV Curing

1. Kho cov tshuaj tiv thaiv tshwm sim hauv vib nas this

Hauv kev kho cov tshuaj tiv thaiv, monomer (Liquid) hloov mus rau polymer (Solid) hauv ob peb feeb.

2. Kev ua haujlwm zoo ib puag ncig

Txij li thaum tag nrho cov khoom siv yog kho los ntawm cov kuab tshuaj tsis muaj photopolymerization, nws yog qhov zoo heev los ua kom tiav cov kev cai ntawm ib puag ncig kev cai thiab kev txiav txim xws li PRTR (Pollutant Release and Transfer Register) Txoj Cai lossis ISO 14000.

3. Zoo meej rau cov txheej txheem automation

UV curable khoom tsis kho tshwj tsis yog raug rau lub teeb, thiab tsis zoo li cov khoom siv hluav taws xob kho tau, nws tsis tau kho maj mam thaum khaws cia. Yog li ntawd, nws lub lauj kaub-lub neej yog luv txaus rau nws siv nyob rau hauv cov txheej txheem automation.

4. Kev kho qhov kub thiab txias yog ua tau

Txij li lub sijhawm ua haujlwm luv luv, nws muaj peev xwm tswj tau qhov kub thiab txias ntawm lub hom phiaj. Qhov no yog ib qho ntawm cov laj thawj vim li cas nws thiaj li siv rau hauv cov khoom siv hluav taws xob uas muaj cua sov feem ntau.

5. Haum rau txhua hom kev thov vim muaj ntau yam khoom siv

Cov ntaub ntawv no muaj qhov siab hardness thiab gloss. Ntxiv mus, lawv muaj nyob rau hauv ntau yam xim, thiab li no tuaj yeem siv rau ntau lub hom phiaj.

3. Txoj Cai ntawm UV Curing Technology

Cov txheej txheem ntawm kev hloov cov monomer (kua) rau hauv polymer (khoom) nrog kev pab ntawm UV hu ua UV Curing E thiab cov khoom siv hluavtaws los kho yog hu ua UV Curable Resin E.

UV Curable Resin yog cov khoom sib xyaw uas muaj xws li:

(a) monomer, (b) oligomer, (c) photopolymerization pib thiab (d) ntau yam additives (stabilizers, fillers, pigments, thiab lwm yam).

(a) Monomer yog cov khoom siv organic uas yog polymerized thiab hloov mus rau hauv cov molecules loj ntawm polymer los ua yas. (b) Oligomer yog cov khoom siv uas twb tau ua rau cov monomers. Ib yam li monomer, oligomer yog polymerized thiab hloov mus rau hauv cov molecules loj los tsim cov yas. Monomer lossis oligomer tsis yooj yim tsim cov tshuaj tiv thaiv polymerization, yog li lawv tau ua ke nrog photopolymerization pib los pib cov tshuaj tiv thaiv. (c) Tus neeg pib photopolymerization zoo siab los ntawm kev nqus ntawm lub teeb thiab thaum muaj kev cuam tshuam, xws li hauv qab no, tshwm sim:

(b) (1) Cleavage, (2) Hydrogen abstraction, thiab (3) Electron hloov.

(c) Los ntawm cov tshuaj tiv thaiv no, cov tshuaj xws li radical molecules, hydrogen ions, thiab lwm yam, uas pib cov tshuaj tiv thaiv yog generated. Lub generated radical molecules, hydrogen ions, thiab lwm yam., tua oligomer los yog monomer molecules, thiab ib tug peb-dimensional polymerization los yog crosslinking cov tshuaj tiv thaiv tshwm sim. Vim yog cov tshuaj tiv thaiv no, yog tias cov molecules muaj qhov loj dua li qhov loj me tau tsim, cov molecules raug UV hloov ntawm cov kua rau cov khoom. (d) Ntau yam additives (stabilizer, muab tub lim, pigment, thiab lwm yam) ntxiv rau UV curable resin muaj pes tsawg leeg raws li xav tau,

(d) muab nws stability, lub zog, thiab lwm yam.

(e) Liquid-state UV curable resin, uas yog ywj siab ntws, feem ntau yog kho los ntawm cov kauj ruam hauv qab no:

(f) (1) Photopolymerization pib nqus UV.

(g) (2) Cov txheej txheem photopolymerization uas tau nqus UV zoo siab heev.

(h) (3) Activated photopolymerization initiators react nrog resin Cheebtsam xws li oligomer, monomer, thiab lwm yam., los ntawm decomposition.

(i) (4) Tsis tas li ntawd, cov khoom no hnov ​​​​mob nrog resin Cheebtsam thiab cov saw hlau tshwm sim. Tom qab ntawd, cov tshuaj tiv thaiv peb-dimensional crosslinking tshwm sim, qhov hnyav molecular nce thiab cov resin kho.

(j) 4. UV yog dab tsi?

(k) UV yog ib qho hluav taws xob nthwv dej ntawm 100 mus rau 380nm wavelength, ntev dua li ntawm X-rays tab sis luv dua li pom cov rays.

(l) UV tau muab faib ua peb pawg hauv qab no raws li nws qhov wavelength:

(m) UV-A (315-380nm)

(n) UV-B (280-315nm)

(o) UV-C (100-280nm)

(p) Thaum UV siv los kho cov resin, cov chav hauv qab no yog siv los ntsuas qhov nqi ntawm UV hluav taws xob:

(q) - Irradiation siv (mW / cm2)

(r) Irradiation siv ib chav tsev

(s) - UV raug (mJ / cm2)

(t) Irradiation zog ib chav tsev thiab tag nrho cov khoom ntawm photons mus txog saum npoo. Cov khoom ntawm irradiation siv thiab lub sijhawm.

(u) - Kev sib raug zoo ntawm UV raug thiab irradiation siv

(v) E = I x T

(w) E = UV raug (mJ/cm2)

(x) I = Intensity (mW/cm2)

(y) T = Lub sij hawm Irradiation (s)

(z) Txij li UV raug xav tau rau kev kho yog nyob ntawm cov khoom siv, lub sijhawm irradiation yuav tsum tau los ntawm kev siv cov qauv saum toj no yog tias koj paub UV irradiation siv.
