Kenyelletso e qaqhileng
UV-1577e sebelisoa ka mokhoa o hlakileng ea moea o mo sitisang (Hals) e fanang ka tšireletso e sebetsang khahlanong le litlamorao tse mpe E sebelisoa hangata indasteri ea indasteri e fapaneng, ho kenyelletsa le Likepi, likhakatso le masela a matla a ho ntlafatsa tikoloho.
UV-1577, e tsejoang ka ka lebitso la eona la lik'hemik'hale lebitso la Bis (1,2,2,2,2,2,6 Hotels. E sebetsa ka mochine o ikhethileng o ikhethang oa ho thibela ho nyopa ha UV-amanang le Polymers. Ha UV Radiation ea UV, UV-1577 e tsoela pele ka liforomo tse feto-fetohang, tse hatisang li-radicals tsa mahala 'me li setse. Sena se thibela ho nyonyeha ha polymer le tahlehelo e latelang ea thepa ea 'mele, joalo ka mebala e felisang, e ngolisoang le mapelong a maholo.
E 'ngoe ea melemo ea bohlokoa ea UV-1577 ke ho feto-fetoha le eona le ho lumellana le thepa e ngata haholo ea li-polymis le thepa. E ka sebelisoa ho Thermoppastics, joalo ka Polyolefins (mohlala, polyethylene le polyproplene le polyproplene Ho boetse ho sebetsa hape ha re ratoa, joalo ka Polyurethanes, EPoxy Resin, le Batho ba sa Hloeng ba Polyester Polyester. Phapang ena e etsa hore UV-1577 e loketse likopo tse fapaneng, ho kenyelletsa lifoto tsa lifilimi, likarolo tse bopehileng, lidheres le liholehelo.
UV-1577 e fana ka botsitso bo boholo ba uxice, ba netefatsa thabo ea bona le katleho leha e le maemong a thata le ho pepesetsoa mahlaseli a uv. E ka mamella mocheso o phahameng oa ho sebetsa nakong ea tlhahiso ea Plymer kapa sengoloa ntle le ho hlanya.
Ho fihlela ts'ebetso e nepahetseng, UV-1577 hangata e sebelisoa hammoho le likhahla tse bobebe tse kang UV tse anngoeng kapa li-antioxidars. Motsoako ona o thusa ho holisa ts'ireletso ea UV le ho ferekana ha lisebelisoa.
Ho bohlokoa ho nahana ka tšebeliso e ikhethileng le tataiso ea ho etsa sebopeho bakeng sa ho kenyelletsa UV-1577 ho lisebelisoa tse fapaneng. Baetsi le basebelisi ba lokela ho bua ka lingoliloeng tsa mahlale, ho na le litataiso tsa sehlahisoa le litloaelo tsa indasteri ea li sebelisa.
UV-1577 ka kakaretso e nkuoa e sireletsehile ha e tšoaroa, e bolokiloe le ho sebelisoa ho latela melao le litataiso tse sebetsang.

Kopo
UV-1577 ke komporo ea lik'hemik'hale e tsejoang ka hore e tsejoa e le Tinuvin 1577 kapa bis (1,2,2 200les) sebacate. Ke seliba se siiloeng se siiloeng (li-Hals) se sebelisoang indastering le likopo. Mona ke tse ling tsa ts'ebeliso ea eona e kholo:
Strimization ea Polymer:UV-1577 e sebelisoa haholo joalo ka seliba sa lebone ho lihlahisoa tsa polymer. E sireletsa sethepu, joalo ka lipopae tse mpe tsa radiation tse kotsi tsa radiation ea UV, ho kenyeletsoa litšila, ho ferekana le ho lahleheloa ke thepa ea mochini. E thusa ho eketsa bophelo bo bophelo ebile e boloka ponahalo ea thepa e thehiloeng polymer.
Likotsi le lipente:UV-1577 e eketsoa ho makhapetla le lipente tsa ho ntlafatsa khatello ea tsona ho UV. E thusa ho thibela mebala e felisang mebala, ho fokotseha ha Gloss, le bokaholimo bo boholo bo bakoang ke ho pepesetsoa ke ho pepesetsoa ke letsatsi.
Plastic:E sebelisoa likopo tse fapaneng tsa polasetiki, ho kenyelletsa Polyolefins (joalo ka polyokerlene le polyproplene le polymphones le pvc (polyvinyl chlonide). UV-1577 e ntlafatsa maemo a leholimo le botsitso ba polasetiki ena, e ba lumella ho boloka thepa ea bona ea nama ea ho pepesetsoa ka ntle ho pepesetsoa.
Lits'ebetso le lifofane:UV-1577 e kenngoa ka likhato le li-sealant ho li sireletsa ho tsoa ho senya. Sena se thusa ho boloka matla a ho ama le ho holisa bophelo ba tšebeletso ea lihlahisoa tsena, haholo likopo tse kantle.
Likhoele le masela:UV-1577 e boetse e sebelisoa khoebong e ngotsoeng ho sireletsa masela le likhoele tse tsoang ho tšenyo ea radiation. E thibela ho hlatsuoa, ho senyeha ha sefahleho le tahlehelo ea matla a ikemiselitseng ho pepesetsoa ke ho pepesetsoa ke UV.
Ho bohlokoa ho hlokomela hore mekhoa e meholo le ea kopo ea UV-1577 e ka fapana ho latela sehlahisoa le indasteri e ikhethang. Baetsi le basebelisi ba UV-1577 ba lokela ho lula ba latela tataiso le litlhahiso bakeng sa ho sebetsana le ts'ebeliso ea eona e nepahetseng.
