PPDI waa 1,4-Phenylene diisocyanate saafi ah (PPDI), lambarka CAS waa 104-49-4. PPDI waa wakiil daaweyn oo horumarsan / fidiye silsilad ah oo loogu talagalay elastomers-ka thermoplastic polyurethane (PU). elastomers-ka shubista ee ku salaysan PPDI waxaa lagu soo bandhigay waxqabad firfircoon oo heer sare ah. Faa'iidada muuqata ayaa ah in taayirrada xawaaraha sare leh ee lagu soo saaro PPDI ay u taagan yihiin heerkul aad u sarreeya marka la eego hawlgal degdeg ah/dhaqdhaqaaq joogto ah. Sidaa darteed, taayirrada ku salaysan PPDI waa xal ku habboon kuwa u baahan cimri dheer, awood rarid weyn iyo baahida sare ee iska caabbinta kulaylka. Guud ahaan, elastomers-ka PU waxaa lagu gartaa xoqid, jeexitaan iyo iska caabin jaris oo aad u fiican marka la barbar dhigo caagagga synthetic-ka ah. Inkasta oo PPDI iyo MDI ay leeyihiin qaabayn isku mid ah, adkeysi iyo sifooyin modulus ah marka loo eego TODI, isocyanate wuxuu leeyahay saamiga hoose ee polyol ilaa polyol ee PPDI. Asal ahaan, elastomers-ka nooca PPDI-ga ayaa ka dabacsan noocyada caadiga ah ee MDI iyo TODI-ga polyurethane-ga nooca TODI. Dhammaan qalabka polyurethane-ka ku shaqeeya, kuwa ku salaysan PPDI waxaa loo yaqaanaa taayirada aadka u walwalsan, tusaale ahaan taayirada fargeetooyinka, gawaarida iyo diyaaradaha; giraangiraha hagaha, giraangiraha mashiinnada; giraangiraha barafka xawaaraha sare leh iyo wixii la mid ah. Marka la soo koobo, nooca PPDI-ga ah ee elastomer-ka ayaa ah doorashada ugu habboon ee loogu talagalay isticmaalka xoqidda ugu hooseysa iyo heerkulka ugu sarreeya. Maalmahan, wakiilka daaweynta PPDI waxaa si weyn loogu isticmaalaa alaabada TPU-ga sida fidiyaha silsiladda ugu weyn, codsiguna wuu sii fidayaa, oo ay ku jiraan giraangiraha O-rings, shaabaddaha haydarooliga, xiddigaha isku xidha iyo daabyada daabacaadda shaashadda.
Faa'iidooyinka faa'iidooyinka aan caadiga ahayn ee kulaylka, xoqidda, jeexjeexa iyo iska caabbinta jarista, elastomer-yada ku salaysan PPDI waxaa si weyn loogu isticmaalaa warshadaha u baahan shaqooyin aan isbeddelin oo aan waaraayn kulaylka. PPDI waa ciyaaryahanka ugu muhiimsan ee TPU (elastomer polyurethane thermoplastic). Shaabadayaasha haydarooliga, masaxayaasha, shaabadaha bistoonka, giraanta O, shaabadaha usha, pulleys-yada codsaday iska caabbinta kulaylka iyo iska caabbinta cadaadiska waa goobo kale oo muhiim ah oo ka mid ah wakiilka daaweynta PPDI. Ha xusin taayirada fargeetooyinka, gawaarida, mashiinnada, diyaaradaha iyo pulleys-yada, giraangiraha, rollers-ka hagaha ee walxaha qoynaya kuwaas oo ah qaybta kale ee elastomer-ka nooca PPDI.
Baakad: 20kg, 40kg, 50kg/durbaan bir ah.
Kaydinta iyo rarista: PPDI aad bay ugu nugul tahay qoyaanka. Biyuhu waxay la falgalaan dhammaan diisocyanates si ay u sameeyaan wax soo saar urea ah oo aan milmi karin. Ha ku darin PPDI cuntada oo iska ilaali inaad ku dhacdo jawi ka sarreeya 30℃. Ka dib marka la isticmaalo, daboolka waa in isla markiiba la xiraa haddii cillad dhacdo. Xaaladaha dibadda ee ku habboon, PPDI waxay shaqaynaysaa ugu yaraan lix bilood laga bilaabo taariikhda la keenay.
