UV CURING Ikoranabuhanga

1. Ikoranabuhanga rya UV rikiza ni iki?

UV Curing Technology ni tekinoroji yo gukiza ako kanya cyangwa gukama mu masegonda aho ultraviolet ikoreshwa mubisigazwa nk'ibitambaro, ibifunga, ibimenyetso bya wino hamwe n'amafoto-birwanya, n'ibindi, kugirango bitere gufotora. Hamwe na olymerisation yuburyo bwo gukanika ubushyuhe cyangwa kuvanga ibintu bibiri, mubisanzwe bifata hagati yamasegonda make kugeza kumasaha menshi kugirango wumishe resin.

Hafi yimyaka 40, iryo koranabuhanga ryakoreshejwe bwa mbere muburyo bwo kumisha icapiro kuri pani kubikoresho byubaka. Kuva icyo gihe, yagiye ikoreshwa mubice byihariye.

Vuba aha, imikorere ya UV ikiza resin yateye imbere cyane. Byongeye kandi, ubwoko butandukanye bwa UV bushobora kuvurwa ubu buraboneka kandi imikoreshereze yazo kimwe nisoko biriyongera cyane, kubera ko ari byiza mubijyanye no kuzigama ingufu / umwanya, kugabanya imyanda, no kugera ku musaruro mwinshi no kuvura ubushyuhe buke.

Byongeye kandi, UV nayo ikwiriye kubumba optique kuva ifite ingufu nyinshi kandi irashobora kwibanda kumurambararo muto, ifasha kubona byoroshye ibicuruzwa bibumbabumbwe neza.

Ahanini, kuba umukozi udashobora gukemuka, ibisigazwa bya UV ntibishobora kubamo ibinyabuzima byose bitera ingaruka mbi (urugero, guhumanya ikirere) kubidukikije. Byongeye kandi, kubera ko ingufu zisabwa mu gukiza ari nkeya kandi imyuka ya gaze karuboni ikaba nke, ubwo buhanga bugabanya umutwaro w’ibidukikije.

2. Ibiranga UV Gukiza

1. Gukiza reaction bibaho mumasegonda

Mugukiza reaction, monomer (Liquid) ihinduka kuri polymer (Solid) mumasegonda make.

2. Ibidukikije byita ku bidukikije

Kubera ko ibikoresho byose byakijijwe cyane na Photopolymerisation idafite imbaraga, ni byiza cyane kuzuza ibisabwa n'amabwiriza ajyanye n'ibidukikije n'amabwiriza nka PRTR (Kwanduza umwanda no kwimura igitabo) cyangwa ISO 14000.

3. Biratunganye kubikorwa byikora

UV ishobora gukira ntishobora gukiza keretse ihuye numucyo, kandi bitandukanye nibikoresho bishobora gukira ubushyuhe, ntabwo ikira buhoro buhoro mugihe cyo kubika. Kubwibyo, inkono-ubuzima bwayo ni ngufi bihagije kugirango ikoreshwe murwego rwo kwikora.

4. Kuvura ubushyuhe buke birashoboka

Kubera ko igihe cyo gutunganya ari gito, birashoboka kugenzura izamuka ryubushyuhe bwikintu. Iyi ni imwe mu mpamvu zituma ikoreshwa muri electronics nyinshi zumva ubushyuhe.

5. Birakwiriye kuri buri bwoko bwa porogaramu kuva ibikoresho bitandukanye birahari

Ibi bikoresho bifite uburebure bwo hejuru hamwe nuburabyo. Byongeye, baraboneka mumabara menshi, nuko rero arashobora gukoreshwa mubikorwa bitandukanye.

3. Ihame rya UV Ikiza Ikoranabuhanga

Inzira yo guhindura monomer (fluid) mo polymer (ikomeye) hifashishijwe UV yitwa UV Curing E naho ibikoresho ngengabuzima bigomba gukira byitwa UV Curable Resin E

UV Curable Resin ni uruganda rugizwe na:

(a) monomer, (b) oligomer, (c) uwatangije Photopolymerisation na (d) inyongeramusaruro zitandukanye (stabilisateur, kuzuza, pigment, nibindi).

(a) Monomer ni ibintu kama kama polymerisime igahinduka molekile nini ya polymer kugirango ikore plastike. (b) Oligomer nigikoresho kimaze kwitwara kuri monomers. Muburyo bumwe na monomer, oligomer ihindurwamo polymerize igahinduka molekile nini kugirango ikore plastike. Monomer cyangwa oligomer ntabwo byoroshye kubyara reaction ya polymerisation, kubwibyo bihujwe na fotopolymerisation yatangije reaction. (c) Uwatangije Photopolymerisation ashimishwa no kwinjiza urumuri kandi iyo reaction, nkibi bikurikira, bibaye:

(b) (1) Cleavage, (2) Gukuramo hydrogen, na (3) Kohereza electron.

(c) Ukurikije iyi reaction, ibintu nka molekile ya radical, hydrogène ion, nibindi, bitangiza reaction birabyara. Molekile zibyara umusaruro, hydrogène ion, nibindi, byibasira molekile ya oligomer cyangwa monomer, kandi reaction ya polymerisiyasi-itatu cyangwa reaction ihuza. Bitewe niyi reaction, niba molekile zifite ubunini burenze ubunini bwagenwe zarakozwe, molekile zihura na UV zihinduka ziva mumazi zikomera. .

(d) kuyiha ituze, imbaraga, nibindi.

()

(f) (1) Abatangije Photopolymerisation bakuramo UV.

(g) (2) Aba batangije Photopolymerisation batwaye UV barishimye.

(h).

(i). Noneho, ibice bitatu-byuzuzanya bigenda bikomeza, uburemere bwa molekile bwiyongera kandi resin irakira.

(j) 4. UV ni iki?

.

(l) UV ishyizwe mubyiciro bitatu byerekanwe hepfo ukurikije uburebure bwayo:

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

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

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

(p) Iyo UV ikoreshwa mugukiza ibisigazwa, ibice bikurikira bikoreshwa mugupima ingano yimirasire ya UV:

(q) - Imbaraga za Irradiation (mW / cm2)

(r) Imbaraga za Irrasiyo kuri buri gace

(s) - UV yerekanwe (mJ / cm2)

(t) Ingufu za Irrasiyo kuri buri gace hamwe nubunini bwa fotone kugirango igere hejuru. Ibicuruzwa bya irradasiyo ubukana nigihe.

(u) - Isano iri hagati ya UV guhura nimbaraga za irrasiyo

(v) E = I x T.

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

(x) I = Ubukomezi (mW / cm2)

(y) T = Igihe cyo kurasa

.

(aa) 5. Kumenyekanisha ibicuruzwa

(ab) Ibikoresho byo mu bwoko bwa UV bikiza

.

(ad) Yubatswe muri UV ibikoresho byo gukiza

.

Ibi bikoresho bigizwe n’itara, irradiator, isoko yingufu nigikoresho gikonjesha. Ibice bidahwitse birashobora kwomekwa kuri irradiator. Ubwoko butandukanye bwimbaraga zituruka kumurongo woroheje uhindura ubwoko bwinshi bwa inverter zirahari.

Ibiro bya UV ibikoresho byo gukiza

Nibikoresho bya UV bikiza bigenewe gukoreshwa kuri desktop. Kubera ko byoroshye, bisaba umwanya muto wo kwishyiriraho kandi ni ubukungu cyane. Birakwiriye cyane kubigeragezo no kugerageza.

Ibi bikoresho bifite uburyo bwubatswe. Igihe icyo aricyo cyose cyifuzwa gishobora gushyirwaho kugirango irrasiyo nziza.

Ibikoresho bya UV bikiza

Ibikoresho byo mu bwoko bwa UV bikiza bitangwa na convoyeur zitandukanye.

Dushushanya kandi tugakora ibikoresho byinshi uhereye kubikoresho bya UV bikiza bifite ibyuma bifata ibyuma bifata ibyuma bigera ku bikoresho binini bifite uburyo butandukanye bwo kohereza, kandi buri gihe dutanga ibikoresho bikwiranye nibisabwa nabakiriya.
