Njira Yochizira UV & EB

Kuchiritsa kwa UV & EB kumatanthawuza kugwiritsa ntchito mtengo wa elekitironi (EB), ultraviolet (UV) kapena kuwala kowoneka kuti apange ma polymeri ndi ma oligomer pagawo. Zinthu za UV & EB zitha kupangidwa kukhala inki, zokutira, zomatira kapena zinthu zina. Njirayi imadziwikanso kuti kuchiritsa ma radiation kapena radcure chifukwa UV ndi EB ndi magwero amphamvu owunikira. Magwero amphamvu a UV kapena machiritso owunikira owoneka bwino nthawi zambiri amakhala nyali zapakatikati za mercury, nyali za pulsed xenon, ma LED kapena ma laser. EB-mosiyana ndi mafotoni a kuwala, omwe amakonda kutengeka kwambiri pamwamba pa zinthu - amatha kulowa kudzera mu zinthu.
Zifukwa Zitatu Zomveka Zosinthira Kukhala UV & EB Technology
Kupulumutsa Mphamvu ndi Kuchita Bwino Kwambiri: Popeza makina ambiri alibe zosungunulira ndipo amafunikira kutsika kwa sekondi imodzi, zopindulitsa zimatha kukhala zazikulu poyerekeza ndi njira zanthawi zonse zokutira. Kuthamanga kwa intaneti kwa 1,000 ft / min. ndizofala ndipo mankhwalawo amakhala okonzeka kuyesedwa ndi kutumizidwa.

Zokwanira Sensitive Substrates: Makina ambiri alibe madzi kapena zosungunulira. Kuphatikiza apo, njirayi imapereka kuwongolera kwathunthu kwa kutentha kwamachiritso ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pazigawo zomwe zimakhudzidwa ndi kutentha.

Zachilengedwe komanso Zosavuta Kuzigwiritsa Ntchito: Zolemba nthawi zambiri zimakhala zopanda zosungunulira kotero kuti utsi ndi kuyaka sikudetsa nkhawa. Njira zochiritsira zopepuka zimagwirizana ndi pafupifupi njira zonse zogwiritsira ntchito ndipo zimafuna malo ochepa. Nyali za UV nthawi zambiri zimatha kuyikidwa pamizere yomwe ilipo kale.

Zopangira Zochiritsira za UV & EB
Ma Monomers ndi midadada yosavuta yomangira yomwe zinthu zopangidwa ndi organic zimapangidwa. Monomer yosavuta yochokera ku chakudya chamafuta ndi ethylene. Ikuyimiridwa ndi: H2C=CH2. Chizindikiro "=" pakati pa mayunitsi awiri kapena ma atomu a kaboni amayimira malo okhazikika kapena, monga momwe akatswiri amatchulira, "chomangira chawiri" kapena kusakhazikika. Ndi malo ngati awa omwe amatha kuchitapo kanthu kuti apange zinthu zazikulu kapena zazikulu zomwe zimatchedwa oligomers ndi ma polima.

Polima ndi gulu la magulu ambiri (ie poly-) obwereza mayunitsi a monoma imodzi. Mawu akuti oligomer ndi mawu apadera omwe amagwiritsidwa ntchito kutanthauza ma polima omwe nthawi zambiri amatha kuchitapo kanthu kuti apange kuphatikiza kwakukulu kwa ma polima. Masamba osasinthika pa oligomers ndi ma monomers okha sangakhudzidwe kapena kuphatikizika.

Pankhani yochiritsa mtengo wa ma elekitironi, ma elekitironi amphamvu kwambiri amalumikizana mwachindunji ndi ma atomu amalo osatulutsidwa kuti apange molekyulu yogwira ntchito kwambiri. Ngati UV kapena kuwala kowoneka kukugwiritsidwa ntchito ngati gwero lamphamvu, chojambula chojambula chimawonjezeredwa kusakaniza. Photoinitiator, ikayatsidwa ndi kuwala, imapanga ma free radical kapena zochita zomwe zimayambitsa kulumikizana pakati pa malo osasinthika.ponents a UV & ude.

Oligomers: Zokwanira zonse zokutira, inki, zomatira kapena zomata zolumikizidwa ndi mphamvu zowunikira zimatsimikiziridwa makamaka ndi ma oligomer omwe amagwiritsidwa ntchito popanga. Oligomers ndi otsika pang'ono ma polima olemera, omwe ambiri amachokera ku ma acrylation amitundu yosiyanasiyana. The acrylation amapereka unsaturation kapena "C = C" gulu mpaka mapeto a oligomer.

Ma Monomers: Ma Monomers amagwiritsidwa ntchito ngati zosungunulira kuti achepetse kukhuthala kwa zinthu zomwe sizinachiritsidwe kuti zithandizire kugwiritsa ntchito. Atha kukhala osagwira ntchito, okhala ndi gulu limodzi lokhalokha kapena malo osakhazikika, kapena osagwira ntchito zambiri. Kusasunthika kumeneku kumawalola kuti achitepo kanthu ndikuphatikizidwa muzinthu zochiritsidwa kapena zomalizidwa, m'malo mogwedezeka mumlengalenga monga momwe zimakhalira ndi zokutira wamba. Multifunctional monomers, chifukwa ali ndi malo awiri kapena angapo zotakasika, kupanga maulalo pakati oligomer mamolekyu ndi monomers ena mu chiphunzitso.

Photoinitiators: Chogwiritsira ntchitochi chimatenga kuwala ndipo chimakhala ndi udindo wopanga ma radicals aulere kapena zochita. Ma radicals aulere kapena zochita ndi mitundu yayikulu yamphamvu yomwe imapangitsa kulumikizana pakati pa malo osasinthika a monomers, oligomers ndi ma polima. Ma Photoinitiators safunikira pamakina ochiritsa ma elekitironi chifukwa ma elekitironi amatha kuyambitsa kuwoloka.

Zowonjezera: Zodziwika kwambiri ndi zolimbitsa thupi, zomwe zimalepheretsa gelation posungira komanso kuchiritsa msanga chifukwa cha kuchepa kwa kuwala. Mitundu yamitundu, utoto, ma defoamers, zolimbikitsa zomatira, zopendekera, zonyowetsa ndi zothandizira zoterera ndi zitsanzo za zowonjezera zina.
