PPDI waa saafi 1,4-Phenylene diisocyanate (PPDI), lambarka CAS waa 104-49-4. PPDI waa wakiilka daawaynta horumarsan / silsilad fidiyeyaasha loogu talagalay poliurethane (PU) elastomerayaasha heerkulbeegga ah. Elastomers-ka tuurista PPDI-ku-saleysan waxaa lagu muujiyey waxqabad firfircoon oo heersare ah. Faa'iidada muuqata ayaa ah in taayirrada xawaaraha sare leh ee lagu soo saaro PPDI ay u taagnaan karaan heerkul aad u sarreeya marka loo eego hawlgal / dhaqdhaqaaq degdeg ah oo joogto ah. Markaa, giraangiraha PPDI-ku-salaysan ayaa ah xalka ugu habboon baahiyahaas nolol-raadsi dheer, awood wax-qabad oo weyn iyo dalabaadka iska caabbinta kulaylka sarreeya. Guud ahaan, elastomers PU waxaa lagu gartaa naaxinta, jeexjeexa iyo iska caabbinta jarista oo aad u fiican marka la barbar dhigo caagadaha synthetic. In kasta oo PPDI iyo MDI ay leeyihiin qaabayn isku mid ah, qallafsanaan iyo sifooyin modules marka la barbar dhigo TODI, isocyanate wuxuu leeyahay saamiga hoose ee molarka hoose ee polyol ilaa polyol gudaha PPDI. Asal ahaan, elastomeriyeyaasha nooca PPDI ayaa ka dabacsanaan badan nooca MDI-dhaqameedka iyo nooca TODI-ga elastomer-ka polyurethane. Dhammaan muraayadaha polyurethane, kuwa ku salaysan PPDI waxay caan ku yihiin taayirada aadka u walaacsan, tusaale ahaan taayirada fargeetada, baabuurta iyo diyaaradaha; rollers hagaha, giraangiraha mashiinada; Rollers-ka xawaaraha sare leh iyo wixii la mid ah. Marka la soo koobo, elastomer-ka nooca PPDI ayaa ah doorashada ugu habboon ee codsashada nabarka ugu hooseeya iyo heerkulka ugu sarreeya. Maalmahan, wakiilka daawaynta PPDI waxaa si weyn loogu isticmaalaa alaabada TPU-da sida silsiladda ugu weyn, codsiguna wuu sii fidayaa, oo ay ku jiraan O-rings, shaabadihii Haydarooliga, xiddigaha isku dhafka ah iyo muraayadaha daabacaadda shaashadda.
Faa'iidooyinka faa'iidooyinka aan caadiga ahayn ee kulaylka, abrasion, jeexjeexa iyo iska caabbinta jarista, PPDI-ku-salaysan elastomers ayaa si ballaaran loogu dabaqaa warshadaha u baahan qallafsanaan adag, hawlaha kulaylka u adkaysta. PPDI waa cayaartoyga furaha u ah TPU (thermoplastic polyurethane elastomer). Xirmooyinka Haydarooliga, masaxadaha, shaabadihii piston, O-rings, shaabadihii ulaha, jiidiyaasha kuwaas oo codsaday caabbinta kulaylka iyo iska caabinta cadaadiska ayaa ah meelaha kale ee muhiimka ah ee wakiilka daweynta PPDI. Ha sheegin taayirada forklifts, baabuurta, mishiinada, diyaaradaha iyo jiidilaha, wheels, rollers hagaha ee walxaha qoyaan kuwaas oo ah qaybta kale ee PPDI-alaastomers nooca.
Xirmooyinka: 20kg, 40kg, 50kg / durbaan bir ah.
Kaydinta iyo gaadiidka: PPDI aad bay ugu nugul tahay qoyaanka. Biyuhu waxay la falgalaan dhammaan diisocyanates si ay u sameeyaan dheesha urea aan la milmi karin. Ha ku darin PPDI iyo cuntada iskana ilaali inaad ku daah-furto deegaan ka sarreeya 30 ℃. Isticmaalka ka dib, daboolka waa in isla markiiba la xidhaa haddii ay cilladi timaado. Marka la eego xaaladaha ku habboon dibadda, PPDI waxay shaqaynaysaa lix bilood ugu yaraan iyada oo laga bilaabo taariikhda la keenay.
