Kedu ihe bụ ihe mkpuchi mkpuchi UV curable?

Ihe mkpuchi ultraviolet curing (UV) bụ ụdị mkpuchi mkpuchi gburugburu ebe obibi ọhụrụ.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 nwere ike ịgwọta bụ nke oligomers, ihe na-arụ ọrụ na-arụ ọrụ, photoinitiators na mgbakwunye.

1. oligomer

Ihe na-emepụta ihe nkiri bụ akụkụ bụ isi nke mkpuchi, ọ bụkwa akụkụ mmiri nke mkpuchi.Ịrụ ọrụ ihe nkiri, ịrụ ọrụ 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.Ọrụ ya na-ekpebi ọrụ ngwa ngwa, ọnụego ọkụ ọkụ, arụmọrụ ihe nkiri na ihe ndị ọzọ pụrụ iche nke mkpuchi tupu ọgwụgwọ.

UV mkpuchi bụ tumadi free radical ìhè usoro ọgwụgwọ, otú oligomers eji bụ dị iche iche acrylic resins.Cationic UV mkpuchi oligomers bụ epoxy resin na vinyl ether ogige.

2. diluent na-arụ ọrụ

Ihe mgbaze na-arụ ọrụ bụ ihe ọzọ dị mkpa nke mkpuchi UV.Ọ nwere ike itughari ma belata viscosity, ma nwee ike ịhazigharị arụmọrụ nke ihe nkiri a gwọrọ.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.N'ime nhazi ahụ n'ezie, mono -, Bi -, na multi-functional acrylates ga-eji ọnụ mee ka ihe onwunwe ha bụrụ ihe nkwado ma nweta mmetụta zuru oke.

3. fotoinitiator

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 mkpuchi UV na-abụghị nke ferrous, photoinitiators kwesịrị ịbụ itx, 907, 369, TPO, 819, wdg Mgbe ụfọdụ, iji belata ihe mgbochi polymerization oxygen ma melite ọnụego ọgwụgwọ UV, a na-agbakwunye obere amine na-arụ ọrụ n'ime UV. mkpuchi .

4. ihe mgbakwunye

Ihe mgbakwunye bụ ihe enyemaka nke mkpuchi UV.Ọrụ nke mgbakwunye bụ imeziwanye arụmọrụ nhazi, arụmọrụ nchekwa na ngwa ngwa 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.
