1. He aha ka UV Curing Technology?
ʻO UV Curing Technology kahi ʻenehana no ka hoʻōla koke ʻana a i ʻole ka maloʻo ʻana i nā kekona kahi e hoʻohana ʻia ai ka ultraviolet i nā resins e like me nā uhi, nā adhesives, ka māka ʻana i ka inika a me nā kiʻi-kūʻē, a me nā mea ʻē aʻe, e kumu i ka photopolymerization. Me nā ʻano hoʻololi olymerization ma ka hoʻomaloʻo ʻana i ka wela a i ʻole ka hui ʻana i ʻelua wai, ʻo ia ka mea maʻamau ma waena o kekahi mau kekona a i kekahi mau hola e hoʻomaloʻo ai i kahi resin.
Ma kahi o 40 mau makahiki i hala aku nei, ua hoʻohana mua ʻia kēia ʻenehana no ka hoʻomaloʻo ʻana i ka paʻi ʻana ma ka plywood no nā mea kūkulu hale. Mai ia manawa, ua hoʻohana ʻia ma nā ʻano kikoʻī.
I kēia mau lā, ua hoʻomaikaʻi nui ka hana o ka resin curable UV. Eia kekahi, loaʻa nā ʻano resins curable UV i kēia manawa a ke ulu wikiwiki nei kā lākou hoʻohana ʻana a me ka mākeke, ʻoiai ʻoi aku ka maikaʻi o ka mālama ʻana i ka ikehu / wahi, hōʻemi i ka ʻōpala, a loaʻa i ka huahana kiʻekiʻe a me ka mālama haʻahaʻa haʻahaʻa.
Eia kekahi, kūpono hoʻi ʻo UV no ka hoʻoheheʻe ʻana i ka optical no ka mea he kiʻekiʻe ka ikehu kiʻekiʻe a hiki iā ia ke nānā aku i nā anawaena wahi liʻiliʻi, e kōkua maʻalahi i ka loaʻa ʻana o nā huahana i hoʻoheheʻe ʻia kiʻekiʻe.
ʻO ka mea maʻamau, ʻo ia he mea hoʻoheheʻe ʻole, ʻaʻole i loaʻa i ka resin hiki ke mālama ʻia o UV kekahi mea hoʻoheheʻe kūlohelohe e hoʻopilikia ai (e laʻa, hoʻohaumia ea) i ke kaiapuni. Eia kekahi, no ka mea ʻoi aku ka liʻiliʻi o ka ikehu e pono ai no ka hoʻōla ʻana a me ka haʻahaʻa o ka hoʻokuʻu ʻana o carbon dioxide, hoʻemi kēia ʻenehana i ke kaumaha o ke kaiapuni.
2. Nā hiʻohiʻona o ka UV Curing
1. Hiki ke ho'ōla i nā kekona
I ka ho'ōla ʻana, hoʻololi ka monomer (Liquid) i ka polymer (Solid) i loko o kekahi mau kekona.
2. ʻO ka pane kaiapuni koʻikoʻi
No ka mea ua ho'ōla maoli ʻia nā mea āpau e ka photopolymerization ʻole solvent-free, ʻoi aku ka maikaʻi o ka hoʻokō ʻana i nā koi o nā lula pili i ke kaiapuni a me nā kauoha e like me PRTR (Pollutant Release and Transfer Register) Law a i ʻole ISO 14000.
3. Pono no ka automation kaʻina hana
ʻAʻole hoʻōla ka mea hiki ke mālama ʻia o UV ke ʻole ka ʻike ʻia i ka mālamalama, a ʻaʻole like me nā mea hiki ke hoʻōla ʻia me ka wela, ʻaʻole e ola mālie i ka wā mālama. No laila, pōkole kona ola pot no ka hoʻohana ʻana i ke kaʻina hana automation.
4. Hiki ke mālama i ka wela haʻahaʻa
No ka pōkole o ka manawa hana, hiki ke hoʻomalu i ka piʻi ʻana o ka mahana o ka mea i hoʻopaʻa ʻia. ʻO kēia kekahi o nā kumu i hoʻohana ʻia ai i ka hapa nui o nā mea uila wela.
5. He kūpono no kēlā me kēia ʻano o ka noi ʻana mai ka loaʻa ʻana o nā ʻano mea like ʻole
Loaʻa i kēia mau mea ka paʻakikī o ka ʻili kiʻekiʻe a me ka nani. Eia kekahi, loaʻa iā lākou i nā kala he nui, a no laila hiki ke hoʻohana ʻia no nā kumu like ʻole.
3. Kumu o ka UV Curing Technology
ʻO ke kaʻina hana o ka hoʻololi ʻana i kahi monomer (wai) i polymer (paʻa) me ke kōkua o UV ua kapa ʻia ʻo UV Curing E a ʻo ka mea hoʻolaʻa synthetic e hoʻōla ʻia ua kapa ʻia ʻo UV Curable Resin E.
ʻO UV Curable Resin kahi pūhui i loaʻa i:
(a) monomer, (b) oligomer, (c) photopolymerization initiator a (d) mau mea hoʻohui like ʻole (stabilizers, fillers, pigments, etc.).
(a) ʻO ka Monomer kahi mea ola i polymerized a hoʻololi ʻia i mau molekala nui o ka polymer e hana i ka plastic. (b) ʻO ka Oligomer kahi mea i hana mua i nā monomers. Ma ke ʻano like me ka monomer, ua polymerized ka oligomer a hoʻololi ʻia i mau mole nui e hana i ka plastic. ʻAʻole hiki i ka Monomer a i ʻole ka oligomer ke hana maʻalahi i ka hopena polymerization, no laila ua hui pū ʻia lākou me kahi mea hoʻomaka photopolymerization e hoʻomaka i ka hopena. (c) Hoʻohauʻoli ka mea hoʻomaka photopolymerization e ka lawe ʻana o ka mālamalama a i ka wā e hana ʻia ai nā hopena, e like me kēia:
(b) (1) Cleavage, (2) Hydrogen abstraction, a (3) Electron transfer.
(c) Ma kēia pane ʻana, ua hoʻokumu ʻia nā mea e like me ka radical radical, hydrogen ions, etc., e hoʻomaka i ka pane. ʻO nā molekala radical i hana ʻia, nā ion hydrogen, a me nā mea ʻē aʻe, e hoʻouka i ka oligomer a i ʻole nā molekole monomer, a loaʻa kahi hopena polymerization ʻekolu a i ʻole crosslinking. Ma muli o kēia pane ʻana, inā hoʻokumu ʻia nā molekala i ʻoi aku ka nui ma mua o ka nui i ʻōlelo ʻia, e hoʻololi nā molekala i ka UV mai ka wai a paʻa. (d) Hoʻohui ʻia nā ʻano mea hoʻohui like ʻole (stabilizer, filler, pigment, etc.) i ka hoʻokumu ʻana o ka resin curable UV e like me ka mea e pono ai.
(d) hāʻawi i ke kūpaʻa, ka ikaika, a pēlā aku.
(e) Hiki ke ho'ōla ʻia ka resin UV-state UV curable, hiki ke hoʻoheheʻe ʻia, maʻamau e hoʻōla ʻia e nā pae aʻe:
(f) (1) Hoʻopili nā mea hoʻomaka photopolymerization i ka UV.
(g) (2) Hoʻohauʻoli kēia mau mea hoʻomaka photopolymerization i komo i ka UV.
(h) (3) Hoʻoulu ʻia nā mea hoʻomaka photopolymerization me nā mea resin e like me ka oligomer, monomer, etc., ma o ka decomposition.
(i) (4) Eia hou, hoʻopili kēia mau huahana me nā ʻāpana resin a hoʻomaka ka hopena o ke kaulahao. A laila, hoʻomaka ka hopena crosslinking ʻekolu-dimensional, piʻi ka paona molecular a hoʻōla ʻia ka resin.
(j) 4. He aha ka UV?
(k) ʻO UV ka nalu electromagnetic o 100 a 380nm ka lōʻihi hawewe, ʻoi aku ka lōʻihi ma mua o nā kukui X akā ʻoi aku ka pōkole ma mua o nā kukuna ʻike ʻia.
(l) Hoʻokaʻawale ʻia ʻo UV i ʻekolu mau ʻāpana i hōʻike ʻia ma lalo nei e like me kona lōʻihi hawewe:
(m) UV-A (315-380nm)
(n) UV-B (280-315nm)
(o) UV-C (100-280nm)
(p) Ke hoʻohana ʻia ʻo UV e hoʻōla i ka resin, e hoʻohana ʻia nā ʻāpana e ana i ka nui o ka radiation UV:
(q) - Ka ikaika o ka hoʻomālamalama ʻana (mW/cm2)
(r) Ka ikaika o ka iradiation ma kēlā me kēia ʻāpana
(s) - Hōʻike UV (mJ/cm2)
(t) Ka ikehu hoʻoheheʻe i kēlā me kēia ʻāpana a me ka nui o nā kiʻi kiʻi e hiki i ka ʻili. Huahana o ka irradiation ikaika a me ka manawa.
(u) - Ka pilina ma waena o ka ʻike ʻana o UV a me ka ikaika o ka irradiation
(v) E=I x T
(w) E=Hōʻike UV (mJ/cm2)
(x) I = Ka ikaika (mW/cm2)
(y) T=Ka manawa hoʻomālamalama (s)
(z) No ka mea e pili ana ka ʻike ʻana o UV no ka ho'ōla ʻana i ka mea, hiki ke loaʻa ka manawa irradiation i makemake ʻia ma o ka hoʻohana ʻana i ke ʻano o luna inā ʻike ʻoe i ka ikaika o ka irradiation UV.
(aa) 5. Hoʻolauna Huahana
(ab) Nā lako hoʻōla UV ʻano lima lima
(ac) ʻO nā mea hana hoʻomaʻamaʻa lima lima ka mea liʻiliʻi a haʻahaʻa loa i ka UV Curing Equipment ma waena o kā mākou laina huahana.
(ad) Nā lako ho'ōla UV i kūkulu ʻia
(ae) Hāʻawi ʻia nā lako hoʻomaʻemaʻe UV i kūkulu ʻia me ka mīkini liʻiliʻi i koi ʻia no ka hoʻohana ʻana i ke kukui UV, a hiki ke hoʻopili ʻia i nā lako i loaʻa kahi conveyor.
Hoʻokumu ʻia kēia mea hana me kahi kukui, kahi irradiator, kahi kumu mana a me kahi mea hoʻomaha. Hiki ke hoʻopili ʻia nā ʻāpana koho i ka irradiator. Loaʻa nā ʻano kumu mana mai kahi inverter maʻalahi a hiki i nā ʻano inverters lehulehu.
Lako Papahana UV Curing
ʻO kēia ka UV Curing Equipment i hoʻolālā ʻia no ka hoʻohana papa. No ka mea paʻa, pono ia i ka liʻiliʻi o ka wahi no ka hoʻokomo ʻana a he mea waiwai loa. He kūpono loa ia no nā hoʻokolohua a me nā hoʻokolohua.
Loaʻa i kēia mea hana kahi hana pani paʻa. Hiki ke hoʻonohonoho ʻia ka manawa hoʻomāmā i makemake ʻia no ka hoʻomālamalama maikaʻi loa.
Mea hoʻolaʻa UV ʻano ʻano conveyor
Hāʻawi ʻia ka Conveyor-type UV Curing Equipment me nā conveyors like ʻole.
Hoʻolālā a hana mākou i nā ʻano mea hana like ʻole mai nā lako UV Curing Equipment me nā mea hoʻokele paʻa a hiki i nā lako nunui me nā ʻano hoʻololi like ʻole, a hāʻawi mau i nā lako kūpono i nā koi o nā mea kūʻai aku.
