Phukusi:220kg / Drum, kapena malinga ndi zomwe kasitomala amafuna.
Manyamulidwe:Sungani padziko lonse lapansi ndi ndege, panyanja ndi FedEx / DHL Express.Perekani mwamsanga ndi yodalirika yobereka.
Kukhazikika:Wokhazikika.Zosagwirizana ndi oxidizing amphamvu, ma alcohols.Ikhoza kuwola mumlengalenga wonyowa, kapena ikakumana ndi madzi.
Popeza PMDI ndi mankhwala osokoneza bongo, kuchitapo kanthu ndi chinyezi cha mumlengalenga kumachitika mosavuta ndipo kumapangitsa kupanga ureas osasungunuka ndi mpweya wa carbon dioxide, zomwe zingayambitse kupanikizika m'mitsuko yotsekedwa ndi kuwonjezeka kwa viscosity ya mankhwala.Choncho, zotengera ziyenera kukhala zowuma ndi zosindikizidwa bwino zitadzaza ndi nayitrogeni.Zotengera za PMDI ziyenera kutsekedwa bwino ndikusungidwa m'nyumba pamalo otentha (15-35 ℃) m'malo olowera mpweya wabwino.Kusungirako pa kutentha kochepa (pansi pa 5 ℃) kungayambitse crystallization;Choncho, zinthu izi ziyenera kutetezedwa ku chisanu.Ngati crystallization ichitika, zinthuzo ziyenera kutenthedwa ndikugudubuza ng'oma mu uvuni wotentha wa 70-80 ℃ kuti zisungunuke, ndipo ziyenera kugwedezeka bwino musanagwiritse ntchito.Kusungunuka m'madzi osamba sikuvomerezeka.Kusungidwa kowonjezera pa kutentha pamwamba pa 50 ℃ sikuvomerezeka kuti tipewe kupangika kwa zolimba zosasunthika komanso kuwonjezereka kwa mamasukidwe.

Polymethylene Polyphenyl Polyisocyanate (PMDI; Polymeric MID) (CAS: 9016-87-9)
PMDI ndi diisocyanate-diphenylmethane(MDI)-based composition yomwe ili ndi ma isocyanates apamwamba kwambiri.Kugwira ntchito ndi za 2.6-2.7.Ndi madzi abulauni pa kutentha kozungulira.
PMDI itha kugwiritsidwa ntchito kwambiri popanga zinthu zolimba za PU thovu loteteza kutentha;Amagwiritsidwanso ntchito mu thovu la isocyanurate, utoto, zomatira, chithovu chomangika, thovu lophatikizika pakhungu, bumper yamagalimoto ndi magawo amkati, thovu lolimba kwambiri komanso matabwa opangidwa, ndi zina zambiri.Choncho, makamaka oyenera kupanga amene amafuna okhwima flowability kachitidwe.
PMDI ndi polima wauinjiniya wogwiritsidwa ntchito popanga thovu lolimba kwambiri la polyurethane ndi retardancy yamoto.Poizoni wa chilengedwe pa mndandanda wa US EPA Toxic Release Inventory List (TRI).
Ntchito kupanga mkulu-ntchito microporous polyurethane elastomer, ❖ kuyanika ndi zofewa polyurethane kudziona peeling thovu, kuphatikizapo nyali, matayala olimba pachimake, fenders galimoto, absorbers mantha, zitsamwitsa mbale, mawilo, mpando mutu mapilo, armrests, Chalk mkati, etc. Amagwiritsidwanso ntchito kwambiri popanga zomatira, zokutira, ma prepolymers ndi semi-prepolymers.
Amagwiritsidwa ntchito popanga mapulasitiki a thovu, zomatira, ndi zina zambiri zomwe zimagwiritsidwa ntchito popanga zida za polyurethane, zomwe zimagwiritsidwa ntchito kwambiri pantchito yomanga, mafakitale amagalimoto, mafakitale amagetsi, monga zida zopangira matenthedwe kapena zofunda.
PMDI imakhala yosasunthika kwambiri komanso imakhala ndi poizoni popuma komanso kuyamwa khungu, koma imakhala ndi magulu a isocyanate (NCO) omwe amatha kuchitapo kanthu ndi chinyezi, pamene kutentha kwa zinthu kumatenthedwa kupitirira 40 ℃ (monga kusungunuka) kapena kugwira ntchito. chilengedwe ndi bwino mpweya wokwanira, izo kuonjezera nthunzi kawopsedwe, kuwonjezera pa ntchito kupopera mbewu mankhwalawa ndondomeko ntchito yomanga, zingachititse kuwonjezeka ndende ya inaimitsidwa particles mu mpweya ndi chifukwa kawopsedwe.Ntchito mu malo ofanana ayenera kuvala mpweya chigoba ndi kupuma, apo ayi, mobwerezabwereza inhalation wa kwambiri ndende nthunzi kungayambitse kupuma ziwengo.Mukangochipeza pakhungu kapena mkati mwa diso, tsukani ndi madzi ndikutsuka khungu ndi sopo ndi madzi.zitsulo kanasonkhezereka ng'oma ma CD, mankhwala sanali kosakhazikika, akhoza kunyamulidwa malinga ndi zofunikira za mankhwala ambiri.Chifukwa cha chikhalidwe cha mankhwala a PMDI, n'zosavuta kuchitapo kanthu ndi madzi kuti apange mankhwala osasunthika a urea ndikutulutsa carbon dioxide, kuchititsa mbiya ya ng'oma ndikuwonjezera kukhuthala.Choncho, panthawi yosungiramo, chidebecho chiyenera kutsekedwa mwamphamvu ndikudzazidwa ndi chitetezo chouma cha nayitrogeni.PMDI iyenera kukhala yotentha (20 ~ 25 deg C) m'chipinda chokhala ndi mpweya wabwino wotsekedwa bwino;Ngati kutentha kutentha ndi otsika kwambiri (m'munsimu 5 deg C) kungachititse kuti mapangidwe crystallization chodabwitsa, choncho ayenera kulabadira antifreeze.Pamene crystallization ichitika, iyenera kutenthedwa ndi kusungunuka pa 70-80 ℃ musanagwiritse ntchito, ndikugwedezeka bwino.Kupewa kusungidwa kwa nthawi yayitali pamwamba pa 50 ℃, Pofuna kupewa mapangidwe a zolimba zosasungunuka ndikuwonjezera kukhuthala.Nthawi ya alumali ya PMDI ndi chaka cha 1 pansi pamikhalidwe yoyenera yosungirako.
Zakuthupi ndi Zamankhwala:Brown mandala madzi ndi fungo lamphamvu.
Ndemanga za Air ndi Madzi:Imakhudzidwa ndi madzi pang'onopang'ono kupanga scum wolemera ndikumasula mpweya woipa.Kupanikizika koopsa kumatha kukwera ngati chidebe chatsekedwa.
Mbiri Yakuchitanso:Polymethylene polyphenyl polyisocyanate imachita ndi madzi pang'onopang'ono kupanga scum wolemera ndikumasula mpweya woipa.Kupanikizika koopsa kumatha kukwera ngati chidebe chatsekedwa.Zotsatira zoyambira za isocyanates ndi ma alcohols ziyenera kuchitidwa mu zosungunulira za inert.Zoterezi popanda zosungunulira nthawi zambiri zimachitika ndi chiwawa chophulika [Wischmeyer 1969].
Hazard Yokayikitsa carcinogen.
Ngozi Yaumoyo:Kukoka mpweya kumayambitsa kupuma, kupweteka pachifuwa, ndi kuchepa kwa m'mapapo;Kupuma, chifuwa, ndi sputum zikhoza kuchitika.Kukhudzana ndi madzi kumasokoneza maso ndi khungu.Kudya kumayambitsa kupsa mtima m'kamwa ndi m'mimba.
Ngozi ya Moto:Khalidwe Pamoto: Zotengera zitha kuphulika.
Mbiri Yachitetezo:Pang'ono poyizoni ndi kumeza.Poizoni pang'ono pokoka mpweya.Carcinogen yokayikitsa yokhala ndi data yoyesera ya neoplastigenic pogwiritsa ntchito njira yopangira.Ikatenthedwa kuti iwonongeke imatulutsa mpweya woipa wa NOx.
