RTECS TR0350000
Polymethylene Polyphenyl Polyisocyanate (PMDI; Polymeric MID) (CAS: 9016-87-9)
PMDI yog diisocyanate-diphenylmethane (MDI)-raws li muaj pes tsawg leeg uas muaj qee qhov ua haujlwm siab dua isocyanates.Lub functionality yog hais txog 2.6-2.7.Nws yog abrown kua ntawm ambient kub.
PMDI tuaj yeem siv dav hauv kev tsim cov PU ua npuas ncauj cov ntaub ntawv kub-insulating;tseem siv hauv isocyanurate ua npuas ncauj, pleev xim, nplaum, cov qauv ua npuas ncauj, cellular integral daim tawv nqaij ua npuas ncauj, tsheb bumper thiab sab hauv qhov chaw, high-resilience ua npuas ncauj thiab hluavtaws ntoo, thiab lwm yam. Vim nws cov qauv muaj pes tsawg leeg, PMDI muaj peev xwm muab tau zoo flowability.Nws yog, yog li ntawd, tshwj xeeb tshaj yog haum rau cov khoom uas yuav tsum tau nruj flowability ntawm systems.
PMDI yog ib qho engineering polymer siv nyob rau hauv cov synthesis ntawm resiliant polyurethane foams nrog nplaim retardancy.Environmental toxin nyob rau hauv US EPA Toxic Release Inventory list (TRI).
Siv rau kev tsim cov microporous polyurethane elastomer, txheej thiab mos polyurethane nws tus kheej-peeling ua npuas ncauj, nrog rau cov khau looj plab hlaub, tsheb fenders, shock absorbers, choke phaj, kauj log, lub taub hau hauv ncoo, armrests, sab hauv accessories, thiab lwm yam. Nws kuj yog siv dav hauv kev tsim cov nplaum, txheej, prepolymers thiab semi-prepolymers.
Siv rau hauv kev tsim cov khoom ua npuas ncauj, nplaum nplaum, thiab lwm yam siv hauv kev tsim cov khoom siv polyurethane, dav siv hauv kev tsim kho, kev lag luam tsheb, kev lag luam hluav taws xob, xws li thermal rwb thaiv tsev cov ntaub ntawv lossis ntaub pua txaj.
PMDI yog volatile heev thiab tsis muaj tshuaj lom nyob rau hauv cov pa nqus pa thiab nqus ntawm daim tawv nqaij, tab sis nws muaj cov isocyanate pawg (NCO) pawg uas yooj yim rau reacts nrog noo noo, thaum cov khoom kub yog rhuab mus rau ntau tshaj 40 ℃ (xws li melting) los yog ua hauj lwm. Ib puag ncig yog qhov cua tsis zoo, nws yuav ua rau kom muaj pa toxicity, ntxiv rau kev siv cov txheej txheem txau cov chaw ua haujlwm, nws tuaj yeem ua rau muaj kev nce ntxiv hauv cov ntsiab lus ntawm cov khoom raug tshem tawm hauv huab cua thiab ua rau toxicity.Ua haujlwm nyob rau hauv ib qho chaw zoo sib xws yuav tsum hnav lub npog ntsej muag roj thiab lub tshuab ua pa, txwv tsis pub, kev nqus pa ntau dhau ntawm cov pa yuav ua rau ua pa ua pa.Thaum koj tau txais nws ntawm daim tawv nqaij lossis hauv qhov muag, yaug nrog dej thiab ntxuav cov tawv nqaij nrog xab npum thiab dej.Galvanized hlau nruas ntim, cov khoom yog non-volatile, tuaj yeem thauj tau raws li cov kev cai ntawm cov tshuaj siv.Vim muaj cov tshuaj lom neeg ntawm PMDI, nws yooj yim rau cov tshuaj tiv thaiv nrog dej los tsim cov urea insoluble thiab tso cov pa roj carbon dioxide, ua rau lub nruas nruas thiab nce viscosity.Yog li ntawd, thaum lub sij hawm khaws cia, lub thawv yuav tsum nruj nreem kaw thiab ntim nrog qhuav nitrogen tiv thaiv.PMDI yuav tsum nyob rau hauv chav tsev kub (20 ~ 25 ° C) nyob rau hauv ib tug zoo-ventilated chav tsev nruj nreem kaw cia;Yog tias qhov ntsuas kub qis dhau (qis dua 5 ° C) tuaj yeem ua rau muaj qhov tshwm sim ntawm crystallization, yog li yuav tsum tau them sai sai rau cov tshuaj tiv thaiv.Thaum crystallization tshwm sim, nws yuav tsum tau rhuab thiab melted ntawm 70-80 ℃ ua ntej siv, thiab stirred zoo.Yuav tsum zam lub sijhawm ntev cia siab tshaj 50 ℃, Txhawm rau kom tsis txhob muaj cov khoom tawg yooj yim thiab ua kom cov viscosity nce.Lub txee lub neej ntawm PMDI yog 1 xyoo raws li qhov tsim nyog cia.
Physical thiab Chemical Properties:Brown pob tshab kua nrog pungent tsw.
Cua & Dej Reactions:Reacts nrog dej maj mam tsim cov khoom hnyav thiab tso pa roj carbon dioxide.Kev phom sij siab tuaj yeem tsim tau yog tias ntim ntim tau kaw.
Reactivity Profile:Polymethylene polyphenyl polyisocyanate reacts nrog dej maj mam tsim cov khoom hnyav thiab tso cov pa roj carbon dioxide.Kev phom sij siab tuaj yeem tsim tau yog tias ntim ntim tau kaw.Base-catalysed cov tshuaj tiv thaiv ntawm isocyanates nrog cawv yuav tsum tau nqa tawm hauv cov kuab tshuaj inert.Cov kev tshwm sim zoo li no thaum tsis muaj cov kuab tshuaj feem ntau tshwm sim nrog kev kub ntxhov [Wischmeyer 1969].
Hazard Questionable carcinogen.
Health Hazard:Inhalation ua rau ua pa tsis xis nyob, hauv siab tsis xis nyob, thiab txo qis pulmonary function;hawb pob, hnoos, thiab hnoos qeev kuj tshwm sim.Tiv tauj nrog kua irritates qhov muag thiab tawv nqaij.Kev noj haus ua rau khaus ntawm qhov ncauj thiab plab.
Hluav Taws Xob:Cwj Pwm Hauv Hluav Taws Xob: Cov thawv ntim khoom tuaj yeem tawg.
Safety Profile:Muaj tshuaj lom los ntawm kev noj tshuaj.Mob me me los ntawm kev nqus pa.Cov lus nug carcinogen nrog kev sim cov ntaub ntawv neoplastigenic los ntawm txoj kev cog.Thaum rhuab mus rau decomposition nws emits cov pa phem ntawm NOx.
