Rarida:Ku gaarsii adduunka oo dhan hawo, badda FedEx/DHL Express.Bixi keenid degdeg ah oo la isku halayn karo.
XasilooniDegganAan ku habboonayn walxaha oksaydhiyeyaasha xooggan, aalkolada.Waxa laga yaabaa inay ku qudhunto hawo qoyan, ama marka biyaha la taabto.
Maadaama PMDI ay tahay kiimiko fal-celisa, falcelinta qoyaanka atmospheric waxay u dhacdaa si fudud waxayna keenaysaa samaynta kaadimareenka aan milmi karin iyo gaasta kaarboon laba ogsaydh, taas oo keeni karta cadaadis ku urura weelasha xidhan iyo kororka viscosity ee alaabta.Sidaa darteed weelashu waa inay gabi ahaanba qalalan yihiin oo si taxadar leh loo xidho ka dib markay ku cidhiidhyaan nitrogen.Weelasha PMDI waa in si fiican loo xiro oo lagu kaydiyaa gudaha heerkulka jawiga (15-35℃) meel hawo fiican leh.Kaydinta heerkulka hooseeya (ka hooseeya 5 ℃) waxay u horseedi kartaa xoogaa crystallization;maaddadan, sidaas darteed, waa in laga ilaaliyaa dhaxan.Haddii crystallization ay dhacdo, walxaha waa in lagu kululeeyaa iyada oo durbaanka lagu rogo foornada hawo kulul 70-80 ℃ si loo dhalaaliyo, ka dibna waa in si fiican loo kiciyaa ka hor isticmaalka.Ku dhalaalida biyaha qubeyska laguma talinayo.Kaydinta la dheereeyey ee heerkulka ka sarreeya 50℃ laguma talinayo in laga hortago samaynta adkaha aan milmi karin iyo korodhka viscosity.

RTECS TR0350000
Polymethylene Polyphenyl Polyisocyanate (PMDI; Polymeric MID) (CAS: 9016-87-9)
PMDI waa diisocyanate-diphenylmethane(MDI) - ka kooban oo ka kooban qaar ka mid ah shaqada sare ee isocyanates.Shaqadu waxay ku saabsan tahay 2.6-2.7.Waa dareere bunni ah oo ku jira heerkulka jawiga.
PMDI waxaa si ballaaran loogu isticmaali karaa soo saarista PU-da adag ee xumbo-xakamaynta qalabka kuleylka;sidoo kale loo isticmaalo xumbo isocyanurate, rinji, xabagta, xumbo qaab-dhismeedka, unug unug xumbo maqaarka integral, bamper baabuurta iyo qaybaha gudaha, xumbo-adkeysiga sare iyo alwaax synthetic, iwm Sababo la xiriira qaab-dhismeedka gaarka ah, PMDI waxay ku siin kartaa socodka wanaagsan.Sidaa darteed, waxay si gaar ah ugu habboon tahay wax soo saarka kaas oo u baahan socodka adag ee nidaamyada.
PMDI waa polymer-ka injineernimada ee loo isticmaalo isku dhafka xumbo polyurethane oo aad u adkeysi leh oo leh dib-u-dhac olol. Sunta deegaanka ee liiska Liiska Soo-saarista Sunta ee US EPA (TRI).
Waxaa loo isticmaalaa soo saarista elastomer microporous polyurethane, dahaarka iyo jilicsan polyurethane xumbo is-dilee, oo ay ku jiraan calaacalaha, taayirada xudunta u adag, baabuurka gawaadhida, nuugista shoogga, taarikada ceejin, taayirrada isteerinka, barkimada madaxa kursiga, gacanta, accessories gudaha, iwm Waxa kale oo si weyn loogu isticmaalaa soo saarista xabagta, dahaarka, prepolymers iyo semi-prepolymers.
Waxaa loo isticmaalaa soo saarista balaastikada xumbo, xabagta, iwm loo isticmaalo soo saarista alaabta poliurethane, oo si weyn loogu isticmaalo warshadaha dhismaha, warshadaha baabuurta, warshadaha korantada, sida qalabka kuleylka kuleylka ama gogosha.
PMDI waa mid aad u kacsan oo ka yar sunta neefsashada neefsashada iyo nuugista maqaarka, laakiin waxay ka kooban tahay kooxaha isocyanate (NCO) kooxaha kuwaas oo ay fududahay in ay la falgalaan qoyaanka, marka heerkulka walxaha lagu kululeeyo in ka badan 40 ℃ (sida dhalaalka) ama shaqada deegaanka waa liidata hawo, waxa ay kordhin doontaa sunta uumiga, marka lagu daro isticmaalka habka buufinta goobta shaqada dhismaha, waxay keeni kartaa in kororka ee fiirsashada ee qayb ka ganaax hawada iyo keeni sunta.Ka shaqaynta deegaan la mid ah waa inay xidhataa maaskaro gaas ah iyo qalab neefsasho, haddii kale, neefsashada soo noqnoqda ee uruurinta xad-dhaafka ah ee uumiga waxay sababi doontaa xasaasiyadaha neefsashada.Isla marka aad ka hesho maqaarka ama gudaha isha, ku raaci biyo oo ku maydh maqaarka saabuun iyo biyo.Baakadaha durbaanka birta ah ee galvanized, alaabtu maaha mid kacsan, waxaa lagu rari karaa iyadoo loo eegayo qodobbada khuseeya kiimikooyinka guud.Sababtoo ah dabeecadda kiimikada firfircoon ee PMDI, way fududahay in lagula falgalo biyaha si loo dhaliyo xeryahooda urea ee aan milmi karin oo la sii daayo kaarboon laba ogsaydh, taasoo keenta foostada durbaanka iyo kordhinta viscosity.Sidaa darteed, inta lagu jiro habka kaydinta, weelka waa in si adag loo xiro oo lagu buuxiyaa ilaalinta nitrogen ee qalalan.PMDI waa in ay ahaataa heerkulka qolka (20 ~ 25 ° C) qol hawo leh oo si adag loo ilaalinayo;Haddii heerkulka kaydinta uu aad u hooseeyo (ka hooseeya 5 ° C) waxay u horseedi kartaa abuuritaanka ifafaale crystallization, markaa waa inaad fiiro gaar ah u yeelataa barafka.Marka crystallization dhacdo, waa in la kululeeyaa oo la dhalaaliyaa 70-80 ℃ ka hor inta aan la isticmaalin, oo si fiican loo walaaqay.Waa in laga fogaadaa kaydinta muddada-dheer ee ka sarreysa 50 ℃, Si looga fogaado samaynta adkaha aan milmi karin iyo kordhinta viscosity.Nolosha shelf ee PMDI waa 1 sano iyadoo lagu hoos jiro xaaladaha kaydinta ku habboon.
Tilmaamaha Jirka iyo Kiimikada:Dareere hufan oo bunni ah oo leh ur xun.
Falcelinta Hawada & Biyaha:Waxay ku falcelisaa biyo si tartiib ah u sameeya wasakh culus oo xoreeya gaasta kaarboon laba ogsaydh.Cadaadis khatar ah ayaa soo bixi kara haddii weel la xidho.
Xogta falcelinta:Polymethylene polyphenyl polyisocyanate waxay la falgashaa biyaha si tartiib tartiib ah u sameysma wasakh culus iyo xoreynta gaasta kaarboon laba ogsaydh.Cadaadis khatar ah ayaa soo bixi kara haddii weel la xidho.Dareen-celinta-catalysed-ka-salaysan ee isocyanates-ka leh aalkolada waa in lagu fuliyaa dareerayaasha aan firfircoonayn.Dareen-celinta noocan oo kale ah maqnaanshaha dareerayaasha waxay badanaa ku dhacaan rabshado qarxa [Wischmeyer 1969].
Khatarta kansarka su'aal la'aan.
Khatarta Caafimaadka:Neefsashada waxay keentaa neef-la'aan, laabta oo xanuun, iyo hoos u dhaca shaqada sambabada;hiinraag, qufac, iyo xaako ayaa sidoo kale dhici karta.Taabashada dareeraha waxay ka xanaajisaa indhaha iyo maqaarka.Cuncunku wuxuu keenaa cuncun afka iyo caloosha.
Khatarta Dabka:Dabeecadda Dabka: Koonteennarada ayaa qarxi kara
Xogta Badbaadada:Sumo dhexdhexaad ah marka la nuugo.Wax yar sun ah neefsashada.Kansarka su'aal leh oo leh xogta neoplastigenic ee tijaabada ah ee dariiqa la geliyo.Marka la kululeeyo si uu u burburo waxa ay sii deysaa qiiq sun ah oo NOx ah.
