I-Polymethylene Polyphenyl Polyisocyanate (PMDI; i-Polymeric MID) (i-CAS: 9016-87-9)
I-PMDI yi-disocyanate-diphenylmethane(MDI)-based composition equlethe ezinye ze-isocyanates eziphezulu zokusebenza.Ukusebenza malunga ne-2.6-2.7.Ilulwelo oluntsundu kumaqondo obushushu akwindawo engqongileyo.
I-PMDI ingasetyenziswa ngokubanzi kwimveliso ye-PU eqinile ye-foam ye-heat-insulating materials;iphinda isetyenziswe kwi-foam ye-isocyanurate, iipeyinti, i-adhesives, i-foam yesakhiwo, i-cellular integral foam yesikhumba, i-automotive bumper kunye neendawo zangaphakathi, i-foam ephezulu kunye ne-synthetic wood, njl.Ngoko ke, ifanelekile ngokukodwa kwimveliso efuna ukuhamba okungqongqo kweenkqubo.
I-PMDI yipolymer yobunjineli esetyenziselwa ukuhlanganiswa kwe-polyurethane foams eyomelela kakhulu kunye ne-flame retardancy.I-toxin ye-Environmental kuluhlu lwe-US EPA Toxic Release Inventory (TRI).
Isetyenziselwa ukwenza i-elastomer ye-microporous polyurethane elastomer esebenza kakhulu, i-coating kunye ne-polyurethane ethambileyo yokuzicoca ugwebu, kuquka i-soles, amatayara aqinileyo angundoqo, ii-fenders zemoto, i-absorbers, iipleyiti zokuminxa, ivili lokuqhuba, imiqamelo yesihlalo, iindawo zokuhlala, izixhobo zangaphakathi, njl. Ikwasetyenziswa ngokubanzi ekwenzeni i-adhesives, i-coatings, i-prepolymers kunye ne-semi-prepolymers.
Isetyenziselwa ukwenza iiplastiki zogwebu, izinto zokuncamathelisa, njl.njl ezisetyenziswa ekwenzeni izinto zepolyurethane, ezisetyenziswa kakhulu kushishino lokwakha, ishishini leemoto, ishishini lombane, njengezinto zokugquma i-thermal okanye zokulala.
I-PMDI iguquguquka kakhulu kwaye inetyhefu encinci ekuphefumleleni ukuphefumla kunye nokufunxa kwesikhumba, kodwa iqulethe amaqela e-isocyanate (NCO) asabela ngokulula ngokufuma, xa ubushushu bezinto eziphathekayo bufudunyezwa ngaphezu kwe-40 ℃ (njengokunyibilika) okanye ukusebenza. okusingqongileyo akuphuhli komoya kakuhle, kuya kwandisa ubutyhefu bomphunga, ukongeza ekusebenziseni inkqubo yokutshiza indawo yokwakhiwa komsebenzi, kunokukhokelela ekwandeni koxinzelelo lwamasuntswana amisiweyo emoyeni kwaye kubangele ubuthi.Umsebenzi kwindawo efanayo kufuneka unxibe imaski yegesi kunye nesixhobo sokuphefumla, ngaphandle koko, ukuphefumla okuphindaphindiweyo koxinzelelo olugqithisileyo lomphunga kuya kubangela ukwaliwa nokuphefumla.Ngokukhawuleza xa uyifumana esikhumbeni okanye ngaphakathi kweso, hlambulula ngamanzi kwaye uhlambe ulusu ngesepha namanzi.Ukupakishwa kwedrum yentsimbi, imveliso ayinakuguquguquka, inokuthuthwa ngokuhambelana nemimiselo echaphazelekayo yeekhemikhali eziqhelekileyo.Ngenxa yobume bemichiza esebenzayo ye-PMDI, kulula ukusabela ngamanzi ukuvelisa i-urea engabonakaliyo kunye nokukhulula i-carbon dioxide, ebangela i-drum barrel kunye nokwandisa i-viscosity.Ngoko ke, ngexesha lenkqubo yokugcina, isitya kufuneka sivalwe ngokungqongqo kwaye sizaliswe ngokukhuselwa kwe-nitrogen eyomileyo.I-PMDI kufuneka ibe kwindawo yokushisa (20 ~ 25 deg C) kwigumbi elinomoya opholileyo ogcinwe ngokungqongqo;Ukuba ukushisa kokugcina kuphantsi kakhulu (ngaphantsi kwe-5 deg C) kunokukhokelela ekubunjweni kwe-crystallization phenomenon, ngoko kufuneka ubeke ingqalelo kwi-antifreeze.Nje ukuba icrystallization yenzekile, kufuneka itshiswe kwaye inyibilikiswe kwi-70-80 ℃ ngaphambi kokusetyenziswa, kwaye ishukunyiswe kakuhle.Kufuneka ugweme ukugcinwa kwexesha elide ngaphezu kwe-50 ℃, Ukuze ugweme ukubunjwa kwezinto eziqinileyo ezinganyibilikiyo kunye nokwandisa i-viscosity.Ubomi beshelufu ye-PMDI ngunyaka we-1 phantsi kweemeko ezifanelekileyo zokugcina.
IiPropati zoMzi kunye nezeMichiza:Ulwelo olumdaka olubalayo olunevumba elinukayo.
Iintshukumo zoMoya naManzi:Iphendula ngamanzi ngokucothayo yenze i-scum enzima kwaye ikhulule igesi yecarbon dioxide.Uxinzelelo oluyingozi lunokwakheka ukuba isikhongozeli sivalekile.
Iprofayile yeReactivity:I-Polymethylene polyphenyl polyisocyanate idibana namanzi ngokucothayo yenze i-scum enzima kwaye ikhulule igesi yecarbon dioxide.Uxinzelelo oluyingozi lunokwakheka ukuba isikhongozeli sivalekile.I-base-catalysed reactions ye-isocyanates ene-alcohols kufuneka iqhutywe kwii-solvents ezingenayo.Ukusabela okunjalo ngokungabikho kwezinyibilikisi kaninzi kwenzeka ngobundlobongela obuqhushumbayo [Wischmeyer 1969].
Ingozi ethandabuzekayo carcinogen.
Ingozi yezempilo:Ukuphefumla kubangela ukuphefumla, ukungakhululeki kwesifuba, kunye nokunciphisa ukusebenza kwemiphunga;ukuphefumla, ukukhohlela, kunye nesikhohlela nazo zinokwenzeka.Ukudibana nolwelo kucaphukisa amehlo kunye nolusu.Ukusela kubangela ukucaphuka komlomo kunye nesisu.
Ingozi yoMlilo:Ukuziphatha eMlilweni: Izikhongozeli zinokugqabhuka.
Iprofayile yoKhuseleko:Ityhefu ephakathi ngokuyiginya.Yityhefu encinci ngokuphefumla.I-carcinogen ethandabuzekayo kunye nedatha yovavanyo ye-neoplastigenic ngendlela yokufakelwa.Xa ishushu ukuze ibole ikhupha imisi eyityhefu yeNOx.
