Fa'aaogāga
O le Photoinitiator TPO o se ituaiga photoinitiator e matuā aogā tele mo le free radical (1) e mitiia i se vaega umi o le galu. Ona o lona lautele tele o le mitiia, o lona tumutumuga aoga o le mitiia e 350-400nm ma e mitiia pea lava pea e oo atu i le 420nm. O lona tumutumuga mitiia e umi atu nai lo o initiators masani. A uma ona fa'amalamalamaina, e mafai ona gaosia ni free radical se lua, benzoyl ma le phosphoryl, ma e mafai ona amataina ai le polymerization. O le mea lea, e vave le saoasaoa o le photocuring. E iai fo'i lona aafiaga photobleaching ma e talafeagai mo le fa'amago loloto o le ata mafiafia ma le uiga o le ufiufi e le samasama. E maualalo le volatility ma e talafeagai mo faiga e fa'avae i le vai.
E masani ona faʻaaogaina i faiga papaʻe ma e mafai ona faʻaaogaina i ufiufi e mafai ona faʻamaʻalili i le UV, vaitusi lomitusi, kelu faʻamaʻalili i le UV, ufiufi alava opitika, photoresists, ipu lolomi photopolymer, resins stereolithography, mea tuʻufaʻatasi, mea faʻatumu nifo, ma isi mea faapena.
I le avea ai ma se photoinitiator, e masani ona faʻaaogaina i vaitusi lolomi lau, vaitusi lolomi lithographic, vaitusi lolomi flexographic, ma ufiufi laupapa. E mafai ona faʻamago atoatoa le TPO i luga o luga paʻepaʻe poʻo luga e tele ai le titanium dioxide pigment. E lautele lona faʻaaogaina i vali eseese. Ona o ona uiga lelei e mitiia ai, e matua talafeagai lava mo vaitusi lolomi lau, lolomi lithographic, vaitusi lolomi flexographic, ma vali laupapa. E le liu samasama le vali, e maualalo lona aafiaga pe a uma le polymerization, ma e leai se toega. E mafai foi ona faʻaaogaina i vali manino, aemaise lava mo oloa e itiiti le manaʻoga mo le manogi. A faʻaaogaina na o ia i polyesters unsaturated o loʻo i ai faiga styrene, e matua maualuga lava lona aoga i le amataga. Mo faiga acrylate, aemaise lava faiga lanu, e masani ona manaʻomia le faʻaaogaina faʻatasi ma amines poʻo acrylamides. I le taimi lava e tasi, e faʻapipiʻiina ma isi photoinitiators e ausia ai le faʻamago atoatoa o le faiga. E matua talafeagai lava mo le faʻamagoina o faiga paʻepaʻe e maualalo le samasama ma vaega mafiafia o ata tifaga. A fa'aogaina le photoinitiator TPO fa'atasi ma le MOB 240 po'o le CBP 393, e mafai ona fa'aleleia atili le lelei o le fa'amamago. O le vaila'au sili lea ona lelei e fa'amama ai le suāu'u mo iunite o le hydrocarbon aromatic petroleum ma e fa'aaogaina fo'i o se formylation reagent i le matata o vaila'au lelei.
Afifiina ma le Felauaiga
20KG/Palu po'o mana'oga o tagata fa'atau.
E patino i oloa masani ma e mafai ona tilivaina i le vasa ma le ea
Tausia ma teuina
Umi e teu ai: 24 masina mai le aso na gaosia ai i totonu o le afifiina muamua e leʻi tatalaina teuina i se nofoaga malūlū ma mago, ʻaloʻese mai le la saʻo, vai.
Faleteuoloa e fa'amamago i le ea, fa'amago i le vevela maualalo, Vavae'ese mai mea e fa'aola ai le ea, 'asi.
