Polymethylene Polyphenyl Polyisocyanate (PMDI; Polymeric MID) (CAS: 9016-87-9)
PMDI o se diisocyanate-diphenylmethane (MDI)-faʻavae tuʻufaʻatasiga o loʻo i ai nisi o isocyanates maualuga atu.O le faʻatinoga e tusa ma le 2.6-2.7.O le vai enaena i le vevela o le siosiomaga.
PMDI e mafai ona faʻaaogaina lautele i le gaosiga o mea faʻamaʻaina PU foam vevela-insulating;faʻaaogaina foʻi i le foam isocyanurate, vali, faʻapipiʻi, foam fausaga, foam paʻu cellular integral, taʻavale taʻavale ma vaega totonu, foam maualuga-maufetuunaʻi ma fafie faʻapipiʻi, ma isi.O le mea lea, e fetaui lelei mo le gaosiga e manaʻomia ai le faʻaogaina o faiga.
PMDI o se polymer inisinia faʻaaogaina i le tuʻufaʻatasia o foaʻi polyurethane sili ona malosi ma le mumu o le afi.
Faʻaaogaina mo le gaosiga o le microporous polyurethane elastomer maualuga, faʻapipiʻiina ma le polyurethane vaivai e paʻu ai le tagata lava ia, e aofia ai alofivae, paʻu malosi, fenders o taavale, faʻalavelave faʻafuaseʻi, faʻafefeteina ipu, uili uili, aluga ulu nofoa, faʻamau, mea faʻaoga, ma isi. .E faʻaaogaina lautele foi i le gaosiga o mea faʻapipiʻi, faʻapipiʻi, prepolymers ma semi-prepolymers.
Faʻaaogaina i le gaosiga o foam plastics, adhesives, ma isi mea faʻaaogaina i le gaosiga o mea polyurethane, faʻaaogaina lautele i fale faufale, fale gaosi oloa, eletise eletise, e pei o mea faʻamalama vevela poʻo moega.
O le PMDI e matua faʻafefete ma faʻaitiitia le oona i le manava manava ma le paʻu o le paʻu, ae o loʻo i ai vaega o le isocyanate (NCO) e faigofie ona tali atu i le susu, pe a vevela le vevela i le sili atu i le 40 ℃ (e pei o le faʻafefe) poʻo le galue. siosiomaga e le lelei ventilated, o le a faateleina ai le ausa toxicity, e faaopoopo atu i le faaaogaina o le faiga spraying nofoaga galuega fausiaina, e mafai ona taitai atu ai i le faateleina o le concentration o vaega le tumau i le ea ma mafua ai oona.O le galue i se si'osi'omaga fa'apea e tatau ona fa'aofuina se ufimata kesi ma le manava, a le o lea, o le fa'aauau pea ona manavaina o le tele o le ausa e mafua ai le manava manava.O le taimi lava e te maua ai i luga o le paʻu poʻo totonu ole mata, fufulu ile vai ma fufulu le paʻu ile fasimoli ma vai.Fa'apipi'i pa'u u'amea u'amea, o le oloa e le fa'afefeteina, e mafai ona feavea'i e tusa ai ma aiaiga talafeagai o vaila'au masani.Ona o le natura kemisi malosi o le PMDI, e faigofie ona tali atu i le vai e faʻatupu ai le faʻaogaina o le urea ma faʻasaʻo le carbon dioxide, mafua ai le paʻu paʻu ma faʻateleina le viscosity.O le mea lea, i le taimi o le teuina, e tatau ona faʻamaufaʻailogaina le atigipusa ma faʻatumu i le puipuiga o le nitrogen mago.PMDI e tatau ona i le vevela potu (20 ~ 25 deg C) i totonu o se potu lelei-ventilated faʻamaufaʻailoga faʻamaufaʻailogaina;Afai o le vevela o le teuina e maualalo tele (i lalo ifo o le 5 deg C) e mafai ona taʻitaʻia ai le faʻavaeina o le tioata, o lea e tatau ai ona gauai atu i le antifreeze.O le taimi lava e tupu ai le tioata, e tatau ona faʻamafanafana ma faʻafefete i le 70-80 ℃ aʻo leʻi faʻaaogaina, ma faʻafefe lelei.E tatau ona aloese mai le teuina umi i luga aʻe o le 50 ℃, Ina ia aloese mai le faʻavaeina o mea e le mafai ona faʻaaogaina ma faʻateleina le viscosity.Ole ola ole PMDI ole 1 tausaga ile tulaga talafeagai e teu ai.
Meatotino Faaletino ma Vailaau:Enaena lanu manino vai ma manogi manogi.
Tali a le Ea & Suavai:E fa'afefe i le vai e fa'atupu malie ai le palapala mamafa ma fa'asa'oloto ai le kasa kaponikyeta.E mafai ona fa'atupula'ia omiga mata'utia pe a fa'amaufa'ailoga pusa.
Tala'aga Fa'agaioiga:O le Polymethylene polyphenyl polyisocyanate e tali atu i le vai e fa'atupu malie ai le palapala mamafa ma fa'asa'oloto ai le kasa oona.E mafai ona fa'atupula'ia omiga mata'utia pe a fa'amaufa'ailoga pusa.E tatau ona faia le fa'aogaina o le isocyanates fa'atasi ma le ava malosi i so'o so'o.O ia gaioiga i le leai o ni solvents e masani lava ona tupu i le vevesi pa [Wischmeyer 1969].
Mata'utia Fa'afesili oona.
Tulaga lamatia ole Soifua Maloloina:O le inhalation e mafua ai le le manava, faʻalavelave faʻalavelave, ma faʻaitiitia le gaioiga o le mama;e mafai fo'i ona tupu le uigi, tale, ma le fue.O le fa'afeso'ota'i ma le vai e fa'afefe ai mata ma le pa'u.O le inuina e mafua ai le ita o le gutu ma le manava.
Tulaga Afi:Amioga i le Afi: E ono pa.
Fa'amatalaga Saogalemu:O'ona feololo ile 'ai.O'ona vaivai pe a manava.Carcinogen fesiligia faʻatasi ma faʻamatalaga neoplastigenic faʻataʻitaʻiga e ala i le faʻaogaina o auala.A fa'avevela e pala e fa'asu'a mai ai le asu oona ole NOx.
