Litšobotsi tsa fisikokhemikhale: PPDI ke ntho e tšoeu e tiileng. Sebaka sa ho qhibiliha: 94 °C. Sebaka sa ho belisa: 110~112 °C (3.3kPa) Botenya: 1.17g/cm3
PPDI ke 1,4-Phenylene diisocyanate (PPDI) e hloekileng, nomoro ea CAS ke 104-49-4. PPDI ke sesebelisoa se tsoetseng pele sa ho phekola/ho eketsa ketane bakeng sa li-elastomer tsa thermoplastic tsa polyurethane (PU). Li-elastomer tsa casting tse thehiloeng ho PPDI li na le ts'ebetso e ntle ea matla. Molemo o totobetseng ke hore mabili a lebelo le phahameng a hlahisoang ka PPDI a ka emela mocheso o phahameng haholo tlas'a ts'ebetso/motsamao o potlakileng le o tsoelang pele. Kahoo, mabili a thehiloeng ho PPDI ke tharollo e phethahetseng bakeng sa litlhoko tseo tse phelang nako e telele, bokhoni bo boholo ba ho jara le litlhoko tse phahameng tsa ho hanyetsa mocheso. Ka kakaretso, li-elastomer tsa PU tse khetholloang ka ho taboha ho hoholo, ho taboha le ho seha ho bapisoa le liraba tsa maiketsetso. Le hoja PPDI le MDI li na le sebopeho se tšoanang, ho thatafala le thepa ea modulus ha li bapisoa le TODI, isocyanate e na le karolelano e tlase ea molar ea polyol ho polyol ho PPDI. Ha e le hantle, li-elastomer tsa mofuta oa PPDI li tenyetseha ho feta li-elastomer tsa polyurethane tsa mofuta oa MDI le TODI. Har'a li-elastomer tsohle tsa polyurethane, tse thehiloeng ho PPDI li tsebahala ka mabili a hatelletsoeng haholo, ke hore, mabili a liforoko, likoloi le lifofane; lirolara tse tataisang, mabili a mechini; lirolara tsa ho skate tse lebelo le holimo le tse ling. Ka bokhutšoanyane, elastomer ea mofuta oa PPDI ke khetho e ntle bakeng sa ts'ebeliso ea ho hohla ka tlase le mocheso o phahameng ka ho fetisisa. Matsatsing ana, moemeli oa ho phekola oa PPDI o sebelisoa haholo lihlahisoa tsa TPU e le extender ea ketane e kholo, 'me ts'ebeliso e ntse e hola, ho kenyeletsoa le li-O-rings, litiiso tsa hydraulic, linaleli tsa ho kopanya le li-squeegee blades tsa ho hatisa skrineng.
Melemo ea melemo ea eona e ikhethang ea ho hanyetsa mocheso, ho taboha, ho taboha le ho seha, li-elastomer tse thehiloeng ho PPDI li sebelisoa haholo indastering e hlokang mesebetsi e sa fetoheng haholo, e tšoarellang mocheso. PPDI ke sebapali sa bohlokoa ho TPU (thermoplastic polyurethane elastomer). Litiiso tsa hydraulic, li-wiper, litiiso tsa piston, li-O-rings, litiiso tsa lithupa, li-pulleys tse kopileng ho hanyetsa mocheso le ho hanyetsa khatello ke masimo a mang a bohlokoa a PPDI treaser. Re sa bue ka mabili a li-forklift, likoloi, mechini, lifofane le li-pulleys, mabili, li-guide rollers bakeng sa lintho tse damping e leng sehlopha se seng sa li-elastomer tsa mofuta oa PPDI.
Pakete: 20kg, 40kg, 50kg/teramo ya tshepe.
Polokelo le lipalangoang: PPDI e utloa bohloko haholo mongobong. Metsi a arabela le diisocyanate tsohle ho etsa di-derivatives tsa urea tse sa qhibiliheng. U se ke ua beha PPDI hammoho le lijo 'me u qobe ho e pepesetsa tikolohong e kaholimo ho 30℃. Kamora ho e sebelisa, sekoahelo se tlameha ho koaloa hang-hang haeba ho se sebetse hantle. Tlas'a maemo a loketseng a kantle, PPDI e sebetsa likhoeli tse tšeletseng bonyane ho tloha ka letsatsi leo e tlisoang ka lona.
