Desmodur RE:Aoao e uiga i le faʻaogaina ma le aoga o isocyanates
Desmodur REose oloa o lo'o iai ile vaega ole isocyanate, fa'apitoa fa'apitoa CAS 2422-91-5. Isocyanates o mea taua ia i le gaosiga o oloa polyurethane eseese, ma Desmodur RE e leai se tuusaunoaga. O lenei tusiga e faʻamoemoe e tuʻuina atu se malamalamaaga loloto o Desmodur RE, o lona faʻaogaina ma le lelei o loʻo ofoina mai i talosaga eseese.
Desmodur REo se polyisocyanate aliphatic e faʻavae ile hexamethylene diisocyanate (HDI). E masani ona faʻaaogaina e avea o se vaega faʻamaʻaʻaina i faʻamalama polyurethane faʻamalama ma faʻapipiʻi faʻapipiʻi. O le kemisi tulaga ese o Desmodur RE ua fa'apena ona lelei mo talosaga e mana'omia ai fa'alavalava maualuga fa'atasi ma le lelei o le tau ma le fa'ama'i. E le gata i lea, o lona fetaui lelei ma le tele o polyols ma solvents e faʻaleleia atili ai lona faʻaogaina i faʻasologa eseese.
O se tasi o itu lelei autu oDesmodur REo lona gafatia e tuʻuina atu le tumau mataʻina ma le tetee UV i coatings. Ole mea lea e fa'apitoa ai mo fa'aoga i fafo, pe a fa'aalia i tulaga faigata o le si'osi'omaga e mafai ona fa'aleagaina ai le fa'atinoga o pa'u fa'aleaganu'u. Pe faʻaaogaina i mea faʻapipiʻi taʻavale, faʻapipiʻi fale gaosi oloa poʻo faʻamaeʻaina fausaga, Desmodur RE e taua tele i le faʻaleleia o le umi o le ola ma foliga o luga o le ufiufi.
I le faʻaopoopoga i lana matafaioi i paʻu, o loʻo faʻaaogaina foi Desmodur RE i le gaosiga o mea faʻapipiʻi maualuga. O lona vave fa'amaloloina o mea ma fa'apipi'i lelei i le tele o substrates e avea ma mea taua i fa'apipi'i fausaga, fa'apipi'i laminating ma fa'amau fa'amau. Desmodur RE adhesives e mafai ona tatalia faʻafitauli faʻainisinia ma mea tau le siosiomaga, ma avea ai i latou ma filifiliga muamua mo le manaʻomia o le faʻaogaina o talosaga i pisinisi eseese.
I le male,Desmodur REofoina formulators le gafatia e fetuutuunai fetuutuunai meatotino o polyurethane coatings ma pipii i manaoga faapitoa. E ala i le fetuutuunai o fua faʻatatau ma faʻapipiʻi Desmodur RE, e mafai ona ausia le tele o uiga faʻatinoga, e aofia ai le maaa, fetuutuunai ma le faʻamaʻi. O lenei tulaga fa'apitoa e mafai ai e tagata gaosi oloa ona fa'amalieina mana'oga 'ese'ese o tagata fa'au'uga i vaega e amata mai i ta'avale ma va'alele i le faufale ma atina'e.
E taua le matauina o lena taimiDesmodur REe ofoina atu le tele o mea lelei i tulaga o le faʻatinoga ma le agavaʻa, ona o le natura faʻaalia o isocyanates, e tatau ona mataʻituina le taulimaina lelei ma le saogalemu. O le fa'aalia i le isocyanates e ono a'afia ai le soifua maloloina, o le mea lea e taua ai le mulimulita'i i ta'iala mo le saogalemu ma fa'aoga mea e puipuia ai le tagata lava ia pe a tagofia Desmodur RE ma isi oloa fa'avae isocyanate.
I se aotelega,Desmodur REo se mea taua i le faʻatulagaina o faʻapipiʻi polyurethane maualuga ma faʻapipiʻi. O lona tumau fa'apitoa, fa'asagaga o le UV ma le agava'a e fai ma mea e mana'omia i le gaosiga o pa'u ma fa'apipi'i mo le tele o fa'aoga. E ala i le malamalama i le faʻaogaina ma le aoga oDesmodur RE, e mafai e tagata gaosi oloa ma tagata fa'au'uga ona fa'aogaina lona gafatia e fausia ai ni oloa polyurethane umi, umi ma maualuga. Ae ui i lea, pe a galulue ma oloa isocyanate, e taua tele le faʻamuamua o faiga saogalemu e faʻamautinoa ai le soifua manuia o tagata faigaluega ma le siosiomaga.
