Ukwahlukaniswa Okulula kwama-UV Resins

I-resin ye-UV, eyaziwa ngokuthi i-photosensitive resin, iyi-oligomer engabhekana nezinguquko zomzimba namakhemikhali ngesikhathi esifushane ngemva kokuchayeka ekukhanyeni, bese i-crosslink futhi iqine.I-UV resin ihlukaniswa kakhulu ibe yi-solvent based UV resin kanye ne-UV resin esekwe emanzini.

I-solvent based UV resin

Ama-solvents ajwayelekile asekelwe kwi-UV resins ikakhulukazi ahlanganisa: i-Unsaturated polyester, i-UV epoxy acrylate, i-UV polyurethane acrylate, i-UV polyester acrylate, i-UV polyether acrylate, i-UV pure acrylic resin, i-UV epoxy resin, i-UV silicone oligomer, njll.

I-resin ye-UV etholakala emanzini

I-resin ye-UV etholakala emanzini ibhekisela kunhlaka ye-UV encibilika emanzini noma engahlakazwa ngamanzi.I-molecule iqukethe inani elithile lamaqembu aqinile we-hydrophilic, njenge-carboxyl, i-hydroxyl, i-amino, i-ether, namaqembu e-acylamine;Futhi iqukethe amaqembu angagcwele, njenge-acryloyl, i-methacryloyl noma amaqembu e-Allyl.Izihlahla ze-UV ezitholakala emanzini zingahlukaniswa zibe izigaba ezintathu: okokugcoba, amanzi ahlakazekayo kanye nokuncibilika emanzini, ikakhulukazi okuhlanganisa izigaba ezintathu: i-polyurethane acrylate yamanzi, i-epoxy acrylate ne-polyester acrylate ephuma emanzini.

I-resin ye-UV esemanzini ngokuvamile iqukethe i-80-90% yenhlaka yamanzi kanye ne-10-20% yezinye izithasiselo.Ngemuva kokumbozwa nokupholishwa, ungqimba oluncane olwakhiwe nge-polymer lushiywa ebusweni be-substrate, olunikeza ukumbozwa ngezici ezihlukile ngenxa yenhlanganisela yefomula ehlukene.Okufana ne-gloss ephezulu, i-matt, i-abrasion resistant, njll.

I-resin ephuma emanzini iyisakhi esiyinhloko se-Z esenhlakani ye-UV esemanzini.Inquma futhi ithinte izakhiwo ze-resin ye-UV ephuma emanzini, njengokucwebezela, ukunamathela, ukumelana nokuhuzuka, ukoma, njll. Ngakho-ke, ukukhethwa okufanele kwe-resin ye-UV ephuma emanzini kuyisihluthulelo sokuthunyelwa ngempumelelo kwe-resin ye-UV ephuma emanzini.

Kunezinhlobo eziningi zama-resin, okuhlanganisa i-rosin yamanzi eguquliwe ye-maleic resin, i-waterborne polyurethane resin, i-waterborne acrylic resin, i-alkyd resin ephuma emanzini, i-amino resin ephuma emanzini, njll ukukhishwa kwamanzi, isicwebezelisi esihle ngemva kokwakheka kwefilimu, ukumelana nokushisa, ukumelana namakhemikhali, isivinini sokumisa ngokushesha, njll., kuyilapho i-acrylic copolymer resin ephuma emanzini ingahlangabezana nezidingo zokunyathelisa nokucwebezela ngezinga elikhulu.Ngakho-ke, lapho ulungiselela i-UV resin ephuma emanzini, isistimu ye-acrylic copolymer yamanzi iba yisinqumo sethu esingcono kakhulu.

I-aqueous acrylic copolymer resin ingahlukaniswa ibe isixazululo se-acrylic resin enamanzi, ukuhlakazeka kwe-acrylic enamanzi, kanye ne-acrylic lotion.I-Acrylic lotion ingahlukaniswa ibe i-acrylic lotion eyenza ifilimu kanye ne-non-forming acrylic lotion.Izakhiwo ze-acrylic copolymer resin zamanzi zenziwe ngama-monomers.Ukusebenza kanye nenqubo yokuhlanganisa.Amanye ama-monomers angathuthukisa ukucwebezela nobulukhuni, kanti amanye anganikeza ukumelana namakhemikhali nokunamathela.Ukuhlola okuningi kuye kwafakazela ukuthi inhlaka ye-UV esemanzini, ehlanganiswe ngokwesayensi nesisombululo se-aqueous acrylic acid kanye ne-acrylic acid lotion, inendawo ekahle.
