Polymethylene Polyphenyl Polyisocyanate (PMDI; Polymeric MID) (CAS: 9016-87-9)
PMDI ndeye diisocyanate-diphenylmethane(MDI)-yakavakirwa kuumbwa ine mamwe epamusoro mashandiro isocyanates.Iko kushanda kunenge 2.6-2.7.Iri mvura yebrown pane ambient tembiricha.
PMDI inogona kushandiswa zvakanyanya mukugadzira yakaomesesa PU furo kupisa-inodzivirira zvinhu;inoshandiswawo mu isocyanrate foam, pendi, adhesives, structural foam, cellular integral skin foam, bumper yemotokari uye zvikamu zvemukati, high-resilience foam uye matanda ekugadzira, etc. Pamusana pekugadzirwa kwayo kwakasiyana-siyana, PMDI inogona kupa kuyerera kuri nani.Izvo, saka, zvakanyanya kukodzera kugadzirwa kunoda kwakasimba kuyerera kwemasystem.
PMDI ipolymer yeinjiniya inoshandiswa mukugadzirwa kwemafuro akasimba epolyurethane ane moto unoramba uripo.Muchetura wepamhepo paUS EPA Toxic Release Inventory list (TRI) list.
Inoshandiswa kugadzira yakakwirira-inoshanda microporous polyurethane elastomer, kukoira uye yakapfava polyurethane self-peeling furo, kusanganisira masosi, yakasimba musimboti matai, mota fenders, shock absorbers, kukachidza ndiro, mavhiri, chigaro musoro mapiro, armrests, mukati accessories, etc. Inoshandiswawo zvakanyanya mukugadzira zvinonamira, machira, prepolymers uye semi-prepolymers.
Inoshandiswa mukugadzira furo mapurasitiki, adhesives, nezvimwewo zvinoshandiswa mukugadzirwa kwe polyurethane zvinhu, zvakanyanya kushandiswa muindasitiri yekuvaka, indasitiri yemotokari, indasitiri yemagetsi, senge thermal insulation zvinhu kana zvekuvata.
PMDI inoputika uye haina muchetura mukufema inhalation uye kunyura kweganda, asi ine masocyanate mapoka (NCO) mapoka ayo ari nyore kuita nehunyoro, kana tembiricha yechinhu ichipisa kupfuura 40 ℃ (sekunyungudika) kana kushanda. nharaunda haina kufefeterwa zvakanaka, ichawedzera mhute yehupfu, mukuwedzera kune kushandiswa kwekupfapfaidza nzira yekuvaka nzvimbo yebasa, inogona kutungamira mukuwedzera kwekusangana kweakaturikwa zvimedu mumhepo uye kukonzera chepfu.Kushanda munzvimbo yakafanana kunofanirwa kupfeka gasi mask uye respirator, zvikasadaro, kudzokororwa kufemerwa kweyakanyanya kuwanda kwemhepo kunokonzeresa allergy yekufema.Paunenge uchinge waiwana paganda kana mukati meziso, simbura nemvura uye wogeza ganda nesipo nemvura.Galvanized iron drum packaging, chigadzirwa hachina kusimba, chinogona kutakurwa zvinoenderana nezvinodiwa zvemakemikari akajairwa.Nekuda kweiyo inoshanda kemikari chimiro chePMDI, zviri nyore kuita nemvura kuti ibudise insoluble urea makomisheni uye kuburitsa kabhoni dhiabhorosi, zvichikonzera dhiramu dhiramu uye kuwedzera viscosity.Nokudaro, panguva yekuchengetedza, chigadziko chacho chinofanira kunge chakanyatsooma chakavharwa uye chizere ne nitrogen yakaoma kudzivirira.PMDI inofanira kunge iri pakushambidzika kwekamuri (20 ~ 25 deg C) muimba inofefetera zvakanaka yakanyatsovharwa kuchengetedza;Kana tembiricha yekuchengetera yakadzikira (pasi pe5 deg C) inogona kutungamira pakuumbwa kwekristalllization phenomenon, saka unofanirwa kuterera kune antifreeze.Kamwe crystallization yaitika, inofanirwa kupiswa uye kunyungudutswa pa70-80 ℃ isati yashandiswa, uye yakamutswa zvakanaka.Inofanirwa kudzivirira kuchengetwa kwenguva refu pamusoro pe50 ℃, Kuti udzivise kuumbwa kweisina kunyungudika solids uye kuwedzera viscosity.Hupenyu hwesherufu yePMDI ndeye 1 gore pasi pemamiriro ekuchengetedza akakodzera.
Zvenyama neKemikari Properties:Mvura yebrown inoonekera uye inonhuwa.
Mhepo & Mvura Mhinduro:Inopindirana nemvura zvishoma nezvishoma ichigadzira heavy scum uye kusunungura carbon dioxide gasi.Dzvinyiriro ine ngozi inogona kukwira kana mudziyo ukavharwa.
Reactivity Profile:Polymethylene polyphenyl polyisocyanate inobata nemvura zvishoma nezvishoma ichigadzira heavy scum uye kusunungura carbon dioxide gasi.Dzvinyiriro ine ngozi inogona kukwira kana mudziyo ukavharwa.Base-catalysed reactions ye isocyanates ine madoro inofanira kuitwa mune inert solvents.Kuita kwakadaro kana pasina zvinonyungudutsa zvinowanzoitika nechisimba chinoputika [Wischmeyer 1969].
Hazard Inobvunza carcinogen.
Dambudziko rehutano:Kufema kunokonzera kufema, kusagadzikana kwechipfuva, uye kuderera kwekushanda kwepulmonary;kufema, kukosora, uye sputum zvinogonawo kuitika.Kubata nemvura kunoshatisa maziso neganda.Kudya kunokonzera kushatirwa kwemuromo nemudumbu.
Moto Hazard:Maitiro muMoto: midziyo inogona kuputika.
Nhoroondo Yekuchengetedza:Muchetura zvine mwero nekumwisa.Muchetura zvishoma nekufemesa.Inopokana kenza yekenza ine yekuyedza neoplasigenic data nekuisa nzira.Kana ichipisa kuti iore inoburitsa huturu hweNOx.
