Ikoranabuhanga ryo Gutunganya UV

1. Ikoranabuhanga ryo Gukiza UV ni iki?

Ikoranabuhanga ryo Gukuraho UV ni ikoranabuhanga ryo gukangura cyangwa kumisha ako kanya mu masegonda aho ultraviolet ishyirwa kuri resins nka coating, kole, wino igaragaza na photo-resists, nibindi, kugira ngo itere photopolymerization. Mu buryo bwo gukora olymerization hakoreshejwe ubushyuhe butuma uruhu rushya cyangwa uruvange rw'amazi abiri, akenshi bifata hagati y'amasegonda make kugeza ku masaha menshi kugira ngo resins yumuke.

Mu myaka igera kuri 40 ishize, iri koranabuhanga ryakoreshejwe bwa mbere mu kumisha icapiro ku plywood mu bikoresho by'ubwubatsi. Kuva icyo gihe, ryakoreshejwe mu nzego runaka.

Vuba aha, imikorere ya resin ivurwa n’imirasire ya UV yateye imbere cyane. Byongeye kandi, hari ubwoko butandukanye bwa resin ivurwa n’imirasire ya UV ubu kandi ikoreshwa ryayo ndetse n’isoko ryayo ririmo kwiyongera cyane, kuko ifite akamaro mu kuzigama ingufu/umwanya, kugabanya imyanda, no gutanga umusaruro mwinshi no kuvura ubushyuhe buke.

Byongeye kandi, UV ikwiriye no gukoreshwa mu gushushanya urumuri kuko ifite ingufu nyinshi kandi ishobora kwibanda ku bunini bw'ibanga buke, ibi bikaba bifasha kubona byoroshye ibikoresho bikozwe neza cyane.

Muri make, kubera ko ari umuti udahumanya ikirere, resine ivurwa n’imirasire ya UV ntabwo irimo umuti w’umwimerere utera ingaruka mbi (urugero: ihumana ry’ikirere) ku bidukikije. Byongeye kandi, kubera ko ingufu zikenewe mu gushonga ari nke kandi imyuka ya dioxyde de carbone ikaba mike, ubu buryo bugabanya umutwaro ku bidukikije.

2. Ibiranga UV Curing

1. Indwara yo kuvura ibaho mu masegonda make

Mu gihe cyo gucika, monomer (Liquid) ihinduka polymer (Solid) mu masegonda make.

2. Uburyo bwiza bwo kwita ku bidukikije

Kubera ko ibikoresho byose bivurwa na photopolymerization idafite solvent, ni ingirakamaro cyane kuzuza ibisabwa n'amabwiriza n'amabwiriza ajyanye n'ibidukikije nka PRTR (Pollutant Release and Transfer Register) cyangwa ISO 14000.

3. Ni byiza cyane mu gukora ikoranabuhanga mu buryo bwikora

Ibikoresho bivurwa n’imirasire y’izuba ntibikira keretse bishyizwe ku mucyo, kandi bitandukanye n’ibikoreshwa mu gushyuha, ntibikira buhoro buhoro mu gihe cyo kubibika. Bityo, igihe cyabyo cyo kuba mu nkono ni gito bihagije ku buryo bishobora gukoreshwa mu buryo bwikora.

4. Gukoresha ubushyuhe buke birashoboka

Kubera ko igihe cyo gutunganya ari gito, birashoboka kugenzura ukwiyongera k'ubushyuhe bw'ikintu kigamije. Iyi ni imwe mu mpamvu ituma ikoreshwa mu bikoresho byinshi by'ikoranabuhanga bikoresha ubushyuhe.

5. Bikwiriye ubwoko bwose bw'ibikoresho kuko hari ibikoresho bitandukanye

Ibi bikoresho bifite ubukana bwinshi kandi birabagirana. Byongeye kandi, biboneka mu mabara menshi, bityo bikaba bishobora gukoreshwa mu mirimo itandukanye.

3. Ihame ry'ikoranabuhanga ryo gupima imirasire y'izuba

Uburyo bwo guhindura monomer (amazi) muri polymer (ikomeye) hifashishijwe UV bwitwa UV Curing E naho ibikoresho by’umwimerere bigomba kuvurwa byitwa UV Curable Resin E

Resin ivura UV ni ikintu kigizwe na:

(a) monomer, (b) oligomer, (c) igikoresho gitangira fotopolymerization na (d) inyongera zitandukanye (ibikomeza, ibyuzuza, ibara, nibindi).

(a) Monomer ni ibintu by’umwimerere bihindurwamo polymeri bigahinduka molekile nini za polymeri kugira ngo bikore pulasitiki. (b) Olimer ni ibintu byamaze gukorana na monomer. Kimwe na monomer, olimer ihindurwamo polymeri igahinduka molekile nini kugira ngo ikore pulasitiki. Monomer cyangwa olimer ntibikora reaction ya polymeri byoroshye, bityo bihuzwa na fotopolymerize itangiza reaction kugira ngo bitangire reaction. (c) Photopolymerize itangiza ishimishwa no kwinjiza urumuri kandi iyo reactions, nk'izi zikurikira, zibayeho:

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

(c) Muri ubu buryo, ibintu nka molecule za radical, hydrogen ions, nibindi, bitangira ubwo buryo birakorwa. Molekyuli za radical zikozwe, hydrogen ions, nibindi, zitera molecule za oligomer cyangwa monomer, hamwe na polymerization cyangwa crosslinking reaction y’ibice bitatu bibaho. Kubera ubwo buryo, iyo molecule zifite ingano irenze ingano yagenwe zikozwe, molecule zihura na UV zihinduka ziva mu mazi zijya mu bintu bikomeye. (d) Inyongera zitandukanye (stabilizer, filler, pigment, nibindi) zongerwa ku mvange ya UV ivurwa uko bikenewe, kugira ngo

(d) kuyiha ituze, imbaraga, n'ibindi.

(e) Resin ivurwa n'imirasire ya UV isanzwe, ishobora gutemba neza, ikunze kuvurwa n'intambwe zikurikira:

(f) (1) Ibikoresho bitangira fotopolymerization bikurura UV.

(g) (2) Izi mashini zitangira gukoresha fotopolymerisation zafashe UV zirashyuha cyane.

(h) (3) Ibikoresho bya fotopolymerization bikora hamwe n'ibice bya resin nka oligomer, monomer, nibindi, binyuze mu kubora.

(i) (4) Byongeye kandi, ibi bicuruzwa bikora hamwe n'ibice bya resin maze hagakurikiraho uburyo bwo guhuza uruhererekane. Hanyuma, uburyo bwo guhuza ibintu butera imbere, uburemere bwa molekile buriyongera maze resin igakira.

(j) 4. UV ni iki?

(k) UV ni umuraba wa elegitoroniki ufite ubunini bwa 100 kugeza kuri 380nm, ukaba muremure kurusha uwa X-rays ariko ukaba mugufi kurusha uwa rays igaragara.

(l) UV igabanyijemo ibyiciro bitatu bigaragara hano hepfo hakurikijwe uburebure bw'umuraba wayo:

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

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

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

(p) Iyo UV ikoreshejwe mu kuvura resin, ibi bikurikira bikoreshwa mu gupima ingano y'imirasire ya UV:

(q) - Ubukana bw'imirasire (mW/cm2)

(r) Ubukana bw'imirasire kuri buri gice

(s) - Indwara ya UV (mJ/ cm2)

(t) Ingufu zo gushyushya imirasire kuri buri gice cy'ubutaka n'ingano yose ya fotoni kugira ngo igere ku buso. Umusaruro w'ubukana n'igihe cyo gushyushya imirasire.

(u) - Isano iri hagati yo kwibasirwa n'imirasire ya UV n'ubukana bw'imirasire

(v) E=I x T

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

(x) I = Ubukana (mW/cm2)

(y) T = Igihe cyo gushyushya imirasire (s)

(z) Kubera ko ubwiyongere bw'imirasire ya UV bukenewe mu gushya biterwa n'ibikoresho, igihe cyo kuyishyiramo gishobora kuboneka hakoreshejwe formula yavuzwe haruguru niba uzi ubukana bw'imirasire ya UV.

(aa) 5. Intangiriro y'ibicuruzwa

(ab) Ibikoresho byo gusiga UV byo mu bwoko bw'ibikoresho byoroshye

(ac) Ibikoresho byo kuvura by’ubwoko bw’ibikoresho byo kuvura ni byo bikoresho bito kandi bihendutse cyane mu bicuruzwa byacu.

(ad) Ibikoresho byo gusiga UV byubatswemo

(ae) Ibikoresho byo gukangura imirasire ya UV byubatswemo bifite uburyo buke bukenewe bwo gukoresha itara rya UV, kandi bishobora guhuzwa n'ibikoresho bifite icyo bitwara.

Ibi bikoresho bigizwe n'itara, iradiateri, isoko y'amashanyarazi n'igikoresho gikonjesha. Ibice bishobora gushyirwa kuri iradiateri. Hari ubwoko butandukanye bw'amasoko y'amashanyarazi kuva kuri inverter yoroshye kugeza kuri inverter z'ubwoko bwinshi.

Ibikoresho byo kuvura UV byo kuri mudasobwa

Iyi ni UV Curing Equipment yagenewe gukoreshwa kuri mudasobwa. Kubera ko ari nto, isaba umwanya muto wo kuyishyiraho kandi ihendutse cyane. Ikwiriye cyane kugeragezwa no kugerageza.

Ibi bikoresho bifite uburyo bwo gufunga bwubatswemo. Igihe cyose imirasire ikenewe ishobora gushyirwaho kugira ngo imirasire ibe myiza cyane.

Ibikoresho byo kuvura UV byo mu bwoko bwa conveyor

Ibikoresho byo gukangura UV byo mu bwoko bwa conveyor bitangwa n'amakompanyi atandukanye.

Dushushanya kandi tugakora ibikoresho bitandukanye kuva ku bikoresho bito byo gukangura UV bifite amakompanyi manini kugeza ku bikoresho binini bifite uburyo butandukanye bwo kohereza, kandi duhora dutanga ibikoresho bijyanye n'ibyo abakiriya bakeneye.
