Theknoloji ea ho phekola UV

1. Theknoloji ea ho phekola UV ke eng?

UV Curing Technology ke thekenoloji ea ho folisa hang-hang kapa ho omisa ka metsotsoana eo ho eona mahlaseli a kotsi a sebelisoang ho li-resin tse kang liphahlo, likhomaretsi, enke ea ho tšoaea le li-photo-resist, joalo-joalo, ho baka photopolymerization.Ka mekhoa ea olymerization reaction ka ho omisa mocheso kapa ho kopanya maro a mabeli, hangata ho nka metsotsoana e seng mekae ho isa ho lihora tse 'maloa ho omisa resin.

Lilemong tse ka bang 40 tse fetileng, theknoloji ena e ile ea sebelisoa ka lekhetlo la pele bakeng sa ho omisa khatiso ka plywood bakeng sa thepa ea mohaho.Ho tloha ka nako eo, e ’nile ea sebelisoa libakeng tse itseng.

Haufinyane tjena, ts'ebetso ea resin e phekolehang ea UV e ntlafetse haholo.Ho feta moo, mefuta e fapaneng ea li-resin tse phekolehang tsa UV e se e fumaneha mme ts'ebeliso ea tsona hammoho le mmaraka e ntse e hola ka potlako, kaha e na le molemo mabapi le ho boloka matla / sebaka, ho fokotsa litšila, le ho fumana tlhahiso e phahameng le kalafo e tlase ea mocheso.

Ntle le moo, UV e boetse e loketse ho bōptjoa ha optical kaha e na le matla a mangata a matla 'me e ka tsepamisa maikutlo ho li-diameter tse fokolang, tse thusang ho fumana lihlahisoa tse entsoeng ka mokhoa o nepahetseng haholo.

Ha e le hantle, kaha ke ntho e sa qhibilihiseng, resin e phekolehang ea UV ha e na mokelikeli leha e le ofe oa tlhaho o bakang litlamorao tse mpe (mohlala, tšilafalo ea moea) tikolohong.Ho feta moo, kaha matla a hlokahalang bakeng sa ho folisa a fokotsehile ’me ho ntšoa ha carbon dioxide e tlaase, theknoloji ena e fokotsa moroalo oa tikoloho.

2. Likarolo tsa Pholiso ea UV

1. Karabelo ea ho folisa e etsahala ka metsotsoana

Karabelong ea ho folisa, monomer (Mokelikeli) o fetoha polymer (Solid) ka mor'a metsotsoana e seng mekae.

2. Karabelo e ikhethang ea tikoloho

Kaha thepa eohle ha e le hantle e phekoloa ke photopolymerization e se nang solvent, ho sebetsa haholo ho phethahatsa litlhoko tsa melao le litaelo tse amanang le tikoloho tse kang PRTR (Pollutant Release and Transfer Register) Molao kapa ISO 14000.

3. E phethehile bakeng sa boiketsetso ba tšebetso

Lintho tse phekolehang tsa UV ha li phekole ntle le ha li pepesitsoe leseli, 'me ho fapana le thepa e phekolehang mochesong, ha li fole butle-butle nakong ea ho bolokoa.Kahoo, pitsa-bophelo ba eona bo bokhutšoane ka ho lekana hore e ka sebelisoa ts'ebetsong ea othomathike.

4. Kalafo e tlase ea mocheso e ka khoneha

Kaha nako ea ts'ebetso e khutšoanyane, hoa khoneha ho laola ho phahama ha mocheso oa ntho e lebisitsoeng.Lena ke le leng la mabaka a etsang hore e sebelisoe ka bongata ba lisebelisoa tsa elektronike tse sa utloeng mocheso.

5. E loketse mofuta o mong le o mong oa kopo kaha lisebelisoa tse fapaneng li fumaneha

Lisebelisoa tsena li na le ho thatafala holimo holimo le ho benya.Ho feta moo, li fumaneha ka mebala e mengata, ka hona li ka sebelisoa merero e fapaneng.

3. Molao-motheo oa Theknoloji ea Pholiso ea UV

Mokhoa oa ho fetola monoma (mokelikeli) hore e be polima (e tiileng) ka thuso ea UV e bitsoa UV Curing E 'me thepa ea maiketsetso e tla phekoloa e bitsoa UV Curable Resin E.

UV Curable Resin ke motsoako o nang le:

(a) monomer, (b) oligomer, (c) photopolymerization initiator le (d) li-additives tse fapa-fapaneng (li-stabilizers, fillers, pigments, joalo-joalo).

(a) Monomer ke ntho ea tlhaho e entsoeng ka polymerized 'me e fetoloa limolek'hule tse kholoanyane tsa polymer ho etsa polasetiki.(b) Oligomer ke boitsebiso bo seng bo ntse bo sebetsana le li-monomers.Ka mokhoa o ts'oanang le monoma, oligomer e entsoe ka polymerized mme e fetoloa limolek'hule tse kholo ho etsa polasetiki.Monomer kapa oligomer ha li hlahise karabelo ea polymerization habonolo, ka hona li kopantsoe le mochini oa photopolymerization ho qala karabelo.(c) Moqapi oa photopolymerization o thabisoa ke ho monya ha leseli le ha karabelo, joalo ka tse latelang, e etsahala:

(b) (1) Cleavage, (2) Ho ntšoa ha haedrojene, le (3) Phetiso ea elektrone.

(c) Ka karabelo ena, lintho tse kang limolek'hule tse matla, li-ion tsa hydrogen, joalo-joalo, tse qalang karabelo lia hlahisoa.Limolek'hule tse hlahisoang ke radical, li-ion tsa hydrogen, joalo-joalo, li hlasela limolek'hule tsa oligomer kapa monomer, 'me ho etsahala polymerization ea mahlakore a mararo kapa karabelo ea crosslinking.Ka lebaka la karabelo ena, haeba limolek'hule tse nang le boholo bo boholo ho feta boholo bo boletsoeng li thehoa, limolek'hule tse pepesehileng ho UV li fetoha ho tloha ho metsi ho ea ho tiileng.(d) Li-additives tse fapaneng (stabilizer, filler, pigment, joalo-joalo) li eketsoa sebopehong sa resin e phekolehang ea UV ha ho hlokahala, ho

(d) e fe botsitso, matla, joalo-joalo.

(e) Liquid-state UV resin e phekolehang, e phallang ka bolokolohi, hangata e phekoloa ka mehato e latelang:

(f) (1) Li-photopolymerization tse qalang li monya UV.

(g) (2) Li-initiators tsena tsa photopolymerization tse kentseng UV li thabile.

(h) (3) Li-activators tsa photopolymerization li sebetsa ka likarolo tsa resin tse kang oligomer, monomer, joalo-joalo, ka ho senyeha.

(i) (4) Ho feta moo, lihlahisoa tsena li sebetsana le likarolo tsa resin 'me ketane e tsoela pele.Joale, karabelo ea likarolo tse tharo tsa crosslinking e tsoela pele, boima ba molek'hule boa eketseha 'me resin ea phekoloa.

(j) 4. UV ke eng?

(k) UV ke leqhubu la motlakase la 100 ho isa ho 380nm wavelength, le lelelele ho feta la X-rays empa le le lekgutshwane ho feta la mahlaseli a bonahalang.

(l) UV e arotsoe ka mekhahlelo e meraro e bontšitsoeng ka tlase ho latela bolelele ba maqhubu a eona:

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

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

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

(p) Ha UV e sebelisoa ho phekola resin, likarolo tse latelang li sebelisoa ho lekanya boholo ba mahlaseli a UV:

(q) - Matla a mahlaseli (mW/cm2)

(r) Matla a mahlaseli ka sebaka sa yuniti

(s) - Ts'oaetso ea UV (mJ/ cm2)

(t) Matla a mahlaseli a motlakase sebakeng se seng le se seng le palo eohle ea li-photon ho fihla holimo.Sehlahisoa sa matla a mahlaseli le nako.

(u) - Kamano lipakeng tsa khanya ea UV le matla a mahlaseli

(v) E=I x T

(w) E=Ho pepeseha ha UV (mJ/cm2)

(x) I =Boima (mW/cm2)

(y) T=Nako ea ho khantša mahlaseli (s)

(z) Kaha khanya ea UV e hlokahalang bakeng sa ho folisa e itšetlehile ka thepa, nako e hlokahalang ea mahlaseli e ka fumanoa ka ho sebelisa foromo e ka holimo haeba u tseba matla a mahlaseli a UV.
