UV curing (UV) mkpuchi bụ ụdị ọhụrụ nke gburugburu enyi na enyi mkpuchi.Ọnụ ọgụgụ ihicha ya dị ngwa ngwa.Enwere ike ịgwọ ya site na ọkụ UV n'ime sekọnd ole na ole, na mmepụta mmepụta dị elu.
Ihe mkpuchi UV na-agwọta na-abụkarị nke oligomers, diluents na-arụ ọrụ, photoinitiators na mgbakwunye.
1. Oligomer
Ihe na-emepụta ihe nkiri bụ isi ihe nke mkpuchi, nke bụ mmiri mmiri nke mkpuchi.Ihe nkiri a na-eme ihe nkiri, ịrụ ọrụ ihe owuwu na ihe ndị ọzọ pụrụ iche nke mkpuchi na-adabere na ihe na-emepụta ihe nkiri.Ihe na-emepụta ihe nkiri nke mkpuchi UV bụ oligomer, na arụmọrụ ya na-ekpebi ihe nrụpụta ụlọ na ọnụọgụ ọkụ ọkụ nke mkpuchi tupu agwọ ọrịa, arụmọrụ ihe nkiri mgbe ọgwụgwọ na ihe ndị ọzọ pụrụ iche.
UV mkpuchi bụ tumadi free radical ìhè usoro ọgwụgwọ, otú oligomers eji bụ ụdị niile nke acrylic resins.Cationic UV mkpuchi oligomers bụ epoxy resin na vinyl ether ogige.
2.Active diluent
Ihe mgbaze na-arụ ọrụ bụ ihe ọzọ dị mkpa nke mkpuchi UV.Ọ nwere ike itughari ma belata viscosity, ma nweekwa ihe onwunwe nke imezi ihe nkiri na-agwọ ọrịa.Acrylate arụ ọrụ monomers nwere nnukwu reactivity na ala volatility, n'ihi ya, a na-eji ọtụtụ ebe na UV mkpuchi.A na-ejikarị esters acrylic eme ihe dị ka ihe na-arụ ọrụ maka mkpuchi UV.Na usoro n'ezie, mono -, bifunctional na multi-functional acrylates ga-eji ọnụ mee ka ihe onwunwe ha dịkwuo mma ma nweta nzube nke mmetụta zuru oke.
3. Onye na-ese foto
Photoinitiator bụ ihe mkpali pụrụ iche na mkpuchi UV.Ọ bụ akụkụ dị mkpa nke mkpuchi UV ma na-ekpebi ọnụọgụ ọgwụgwọ UV nke mkpuchi UV.
Maka mkpuchi mkpuchi UV na-enweghị agba, 1173, 184, 651 na bp/ tertiary amine na-ejikarị eme ihe dị ka fotoinitiators.184 nwere ọrụ dị elu, obere isi na nguzogide na-acha odo odo, ọ bụ fotoinitiator na-ahọrọ maka mkpuchi UV na-acha odo odo.Iji meziwanye ọnụego ọgwụgwọ ọkụ, a na-ejikarị ya na TPO.
Maka ihe mkpuchi UV na-acha agba, ndị na-ese foto kwesịrị ịbụ itx, 907, 369, TPO, 819, wdg. Mgbe ụfọdụ, iji belata nkwụsị nke ikuku oxygen polymerization ma melite ọnụego ọgwụgwọ UV, a na-agbakwunye obere amine reactive na-agbakwụnye na mkpuchi UV.
4. Ihe mgbakwunye
Ihe mgbakwunye bụ ihe enyemaka nke mkpuchi UV.Ọrụ nke mgbakwunye bụ iji melite arụmọrụ nhazi, ọrụ nchekwa na ịrụ ọrụ nke mkpuchi, melite arụmọrụ ihe nkiri na inye ihe nkiri ahụ ụfọdụ ọrụ pụrụ iche.Ihe mgbakwunye a na-ejikarị eme ihe maka mkpuchi UV gụnyere defoamer, onye na-ahụ maka ọkwa ọkwa, wetting dispersant, adhesion promoter, matting agent, polymerization inhibitor, wdg, nke na-arụ ọrụ dị iche iche na mkpuchi UV.
