PPDI yog 1,4-Phenylene diisocyanate (PPDI) ntshiab, CAS tus lej yog 104-49-4. PPDI yog ib qho tshuaj kho kom zoo / cov saw hlau txuas rau polyurethane (PU) thermoplastic elastomers. PPDI-based casting elastomers muaj kev ua tau zoo heev. Qhov zoo dua yog tias cov log ceev ceev tsim nrog PPDI tuaj yeem sawv rau qhov kub siab dua hauv qab kev ua haujlwm / kev txav mus los sai thiab txuas ntxiv. Yog li, PPDI-based log yog qhov kev daws teeb meem zoo tshaj plaws rau cov neeg xav tau lub neej ntev, muaj peev xwm thauj khoom loj thiab kev xav tau kub siab. Feem ntau, PU elastomers muaj qhov zoo heev abrasion, tear thiab txiav tsis kam piv rau cov roj hmab hluavtaws. Txawm hais tias PPDI thiab MDI muaj cov qauv zoo sib xws, hardness thiab modulus piv rau TODI, isocyanate muaj qhov sib piv qis dua ntawm polyol rau polyol hauv PPDI. Yeej, PPDI-hom elastomers muaj kev ywj pheej ntau dua li cov MDI-hom thiab TODI-hom polyurethane elastomers ib txwm muaj. Ntawm txhua cov polyurethane elastomers, cov PPDI-based yog paub txog cov log uas muaj kev ntxhov siab heev, piv txwv li cov log tsheb rau forklifts, tsheb thiab dav hlau; cov log qhia, cov log rau tshuab; cov log skate ceev ceev thiab lwm yam. Hauv ntej, PPDI-hom elastomer yog qhov kev xaiv zoo tshaj plaws rau kev siv qis tshaj plaws thiab kub tshaj plaws. Niaj hnub no, PPDI curing agent siv dav hauv TPU-khoom ua lub ntsiab saw extender, thiab daim ntawv thov txuas ntxiv nthuav dav, suav nrog O-rings, hydraulic seals, coupling stars thiab screen printing squeegee blades.
Vim nws cov txiaj ntsig zoo kawg nkaus ntawm kev tiv taus kub, kev sib txhuam, kev tsim kua muag thiab kev txiav, PPDI-based elastomers tau siv dav hauv kev lag luam uas xav tau kev ua haujlwm tsis tshua muaj kev hloov pauv, kev ua haujlwm ruaj khov kub. PPDI yog tus neeg ua si tseem ceeb hauv TPU (thermoplastic polyurethane elastomer). Cov foob hydraulic, cov wipers, cov foob piston, O-rings, cov foob pas nrig, cov pulleys uas xav tau kev tiv taus kub thiab kev tiv taus siab yog lwm qhov tseem ceeb ntawm PPDI curing agent. Tsis hais txog cov log tsheb rau forklifts, tsheb, tshuab, dav hlau thiab pulleys, log, cov menyuam qhia rau cov ntsiab lus dampening uas yog lwm pawg rau PPDI-hom elastomers.
Ntim: 20kg, 40kg, 50kg / hlau nruas.
Kev Khaws Cia thiab Kev Thauj Mus Los: PPDI rhiab heev rau cov dej noo. Dej ua rau cov diisocyanates sib xyaw ua ke los tsim cov urea derivatives uas tsis yaj. Tsis txhob muab PPDI tso nrog zaub mov thiab tsis txhob muab tso rau hauv qhov chaw kub tshaj 30 ℃. Tom qab siv, lub hau yuav tsum kaw tam sim ntawd yog tias muaj teeb meem. Nyob rau hauv cov xwm txheej sab nraud tsim nyog, PPDI siv tau tsawg kawg yog rau lub hlis nrog rau hnub uas nws xa tuaj.
