Ama-Oligomers ama-molecule ahlanganisa amayunithi ambalwa aphindaphindayo, futhi ayizingxenye eziyinhloko zamayinki alaphekayo e-UV. Oyinki abelaphekayo be-UV bangoyinki abangomiswa futhi belapheke ngokushesha ngokuchayeka ekukhanyeni kwe-ultraviolet (UV), okubenza balungele izinqubo zokuphrinta nezokumboza ngesivinini esikhulu. Ama-Oligomers adlala indima ebalulekile ekunqumeni izakhiwo nokusebenza kweziyinki ezilaphekayo ze-UV, njenge-viscosity, ukunamathela, ukuguquguquka, ukuqina, nombala.
Kunezigaba ezintathu eziyinhloko zama-oligomers alaphekayo e-UV, okuyi-epoxy acrylates, i-polyester acrylates, nama-urethane acrylates. Ikilasi ngalinye linezici zalo kanye nokusetshenziswa kwalo, kuye ngohlobo lwe-substrate, indlela yokwelapha, kanye nekhwalithi efiswayo yomkhiqizo wokugcina.
Ama-epoxy acrylates ama-oligomer anamaqembu e-epoxy emhlane wawo, namaqembu e-acrylate ekugcineni kwawo. Baziwa ngokusebenza kwabo kabusha okuphezulu, i-viscosity ephansi, nokumelana okuhle kwamakhemikhali. Kodwa-ke, banezihibe ezithile, njengokungaguquguquki kahle, ukunamathela okuphansi, nokuthambekela kokuphuzi. Ama-epoxy acrylates afanele ukuphrinta kuma-substrates aqinile, njengensimbi, ingilazi, nepulasitiki, kanye nezinhlelo zokusebenza ezidinga ukucwebezela okuphezulu nobulukhuni.
Ama-polyester acrylates ama-oligomer anamaqembu e-polyester emhlane wawo, namaqembu e-acrylate ekugcineni kwawo. Baziwa ngokusebenza kabusha okumaphakathi, ukushwabana okuphansi, nokuguquguquka okuhle. Kodwa-ke, ziphinde zibe nezithiyo ezithile, njengokubonakala okuphezulu kwe-viscosity, ukumelana namakhemikhali aphansi, nokukhipha iphunga. Ama-polyester acrylate afanele ukuphrinta kuma-substrates aguquguqukayo, njengephepha, ifilimu, nendwangu, kanye nezinhlelo zokusebenza ezidinga ukunamathela okuhle nokunwebeka.
Ama-Urethane acrylates ama-oligomer anamaqembu e-urethane emhlane wawo, namaqembu e-acrylate ekugcineni kwawo. Baziwa ngokusebenza kabusha okuphansi, i-viscosity ephezulu, nokuguquguquka okuhle kakhulu. Kodwa-ke, banezihibe ezithile, njengezindleko eziphezulu, ukuvimbela umoya-mpilo ophezulu, kanye nesivinini esiphansi sokwelapha. Ama-urethane acrylates afaneleka ukuphrinta kuma-substrates ahlukahlukene, njengokhuni, isikhumba, nerabha, kanye nezinhlelo zokusebenza ezidinga ukuqina okuphezulu nokumelana nemihuzuko.
Sengiphetha, ama-oligomers abalulekile ekwakhiweni nasekusebenzeni koyinki obulaphekayo be-UV, futhi angahlukaniswa abe amakilasi amathathu ayinhloko, okuyi-epoxy acrylates, i-polyester acrylates, nama-urethane acrylates. Ikilasi ngalinye linezinzuzo zalo kanye nokubi, ngokuya ngesicelo kanye ne-substrate. Ukuthuthukiswa kwama-oligomers kanye noyinki we-UV kuyinqubo eqhubekayo, futhi izinhlobo ezintsha zama-oligomers nezindlela zokwelapha ziyacutshungulwa ukuze kuhlangatshezwane nezidingo ezikhulayo zemboni kayinki.
