Ukunyanga kwe-UV & EB ngokuqhelekileyo kuchaza ukusetyenziswa kwe-electron beam (EB), i-ultraviolet (UV) okanye ukukhanya okubonakalayo ukwenza i-polymerize indibaniselwano ye-monomers kunye ne-oligomers kwi-substrate. I-UV & EB imathiriyeli inokwenziwa ibe yi-inki, i-coating, i-adhesive okanye enye imveliso. Inkqubo ikwabizwa ngokuba kukunyanga ngemitha okanye i-radcure kuba i-UV kunye ne-EB ziyimithombo yamandla eqaqambileyo. Imithombo yamandla e-UV okanye ukunyanga okubonakalayo okubonakalayo zizibane zoxinzelelo oluphakathi lwemercury, izibane ze-xenon ezipholileyo, ii-LED okanye iilaser. I-EB-ngokungafaniyo neefotoni zokukhanya, ezithanda ukufunxwa ikakhulu kumphezulu wezinto eziphathekayo-unamandla okungena nge-matter.
Izizathu eziNtathu ezinyanzelisayo zokuguqulela kwi-UV & EB Technology
Ukongiwa kwamandla kunye nokuPhuculwa kweMveliso: Kuba uninzi lweenkqubo azinasombululi kwaye zifuna ngaphantsi kwesesibini sokuvezwa, iinzuzo zemveliso zinokuba zikhulu xa kuthelekiswa neendlela eziqhelekileyo zokugquma. Izantya zomgca wewebhu we-1,000 ft/min. ziqhelekile kwaye imveliso ilungele ngokukhawuleza ukuvavanywa kunye nokuthunyelwa.
Ifanele iiSubstrates eziSensitive: Iinkqubo ezininzi azinamanzi okanye isinyibilikisi. Ukongeza, inkqubo ibonelela ngolawulo olupheleleyo lobushushu bokunyanga iyenza ilungele ukusetyenziswa kwiisubstrates ezibuthathaka.
Ukusingqongileyo kunye noBudlelwane boMsebenzisi: Imizobo iqhelekile ukunyibilika ngaphandle kwento enyibilikayo ngoko ukukhutshwa kunye nokutsha akuyongxaki. Iinkqubo zokunyanga ukukhanya ziyahambelana phantse zonke iindlela zokusetyenziswa kwaye zifuna ubuncinci bendawo. Izibane ze-UV zidla ngokufakelwa kwiintambo zemveliso ezikhoyo.
Ukwakhiwa kweUV kunye ne-EB eNyangekayo
IiMonomers zezona zitena zilula zokwakha ezivela kuzo izinto zokwenziwa kwezinto eziphilayo. I-monomer elula evela kwisondlo se-petroleum yi-ethylene. Imelwe ngu: H2C=CH2. Isimboli "=" phakathi kweeyunithi ezimbini okanye iiathom zekhabhoni zimela indawo esebenzayo okanye, njengoko iikhemisti zibhekisa kuyo, "ibhondi ephindwe kabini" okanye i-unsaturation. Ziziza ezifana nezi ezikwaziyo ukusabela ukwenza izinto ezinkulu okanye ezinkulu zeekhemikhali ezibizwa ngokuba zii-oligomers kunye neepolima.
Ipolymer liqela labaninzi (okt ipholy-) eziphinda iiyunithi zemonoma enye. Igama elithi oligomer ligama elikhethekileyo elisetyenziselwa ukumisela ezo polima ezihlala zinokuthi ziphinde ziphenduleke ukwenza indibaniselwano enkulu yeepolima. Iziza ze-unsaturation kwii-oligomers kunye ne-monomers zodwa aziyi kusabela okanye zidibanise.
Kwimeko yokunyangwa kwe-electron beam, ii-electron zamandla aphezulu zisebenzisana ngokuthe ngqo kunye nee-athom zesayithi elingaxutywanga ukuvelisa i-molecule esebenzayo kakhulu. Ukuba i-UV okanye ukukhanya okubonakalayo kusetyenziswa njengomthombo wamandla, i-photoinitiator yongezwa kumxube. I-photoinitiator, xa ibonakaliswe ekukhanyeni, yenza i-radical yasimahla okanye iintshukumo eziqalisa ukudibanisa phakathi kweendawo ezingezizo.ponents ze-UV & ude.
I-Oligomers: Iipropati ezipheleleyo zayo nayiphi na into yokugquma, i-inki, i-adhesive okanye i-binder crosslinked ngamandla e-radiant imiselwa ngokuyinhloko ngama-oligomers asetyenziswe ekuqulunqweni. Ii-Oligomers ziyi-polymers ezinobunzima obuphantsi be-molecular, uninzi lwazo lusekelwe kwi-acrylation yezakhiwo ezahlukeneyo. I-acrylation inika i-unsaturation okanye iqela elithi "C = C" kwiiphelo ze-oligomer.
Iimonomers:IiMonomers zisetyenziswa ikakhulu njengezinto zokuthambisa ukuthoba i-viscosity yezinto ezinganyangekanga ukuququzelela ukusetyenziswa. Zinokuthi zibe yinto enye, equlethe kuphela iqela elilodwa elisebenzayo okanye indawo ye-unsaturation, okanye i-multifunctional. Oku kungabikho kwe-unsaturation kuvumela ukuba basabele kwaye bafakwe kwizinto eziphilisiweyo okanye ezigqityiweyo, kunokuba ziguquke emoyeni njengoko ziqhelekile kunye neengubo eziqhelekileyo. Iimonomers ezisebenzayo, ngenxa yokuba ziqulethe iisayithi ezimbini okanye ngaphezulu ezisebenzayo, zenza izixhumanisi phakathi kwe-oligomer molecules kunye nezinye iimonomers ekuqulunqweni.
Iifotonitiators: Esi sithako sifunxa ukukhanya kwaye sinoxanduva lokuvelisa iiradicals zasimahla okanye izenzo. I-radicals yamahhala okanye izenzo zintlobo zamandla aphezulu ezenza ukuba kubekho ukuwela phakathi kweendawo ezingabonakaliyo ze-monomers, i-oligomers kunye ne-polymers. Iifotonitiators azifuneki kwiinkqubo ze-electron beam ephiliswayo kuba ii-electron ziyakwazi ukuqalisa ukudibanisa.
Izongezo: Ezona zixhaphakileyo zizizinzi, ezithintela i-gelation kwindawo yokugcina kunye nokunyanga kwangaphambi kwexesha ngenxa yamanqanaba asezantsi okukhanya. Imibala yemibala, iidayi, i-defoamers, abagqugquzeli bokubambelela, i-flatting agents, i-agent yokumanzisa kunye ne-slip aids yimizekelo yezinye izongezo.
