Amathiphu angumongo: I-PP ingahlukaniswa ngokuya ngama-substrates ahlukene, ekuhlukaniseni kusengaba izincazelo ezahlukene zesilinganiso sokuncibilika kokuncibilika, futhi ngisho nangokusetshenziswa kwezithasiselo zezimpahla zomuntu ngamunye ukuze kunqunywe ukusetshenziswa kokucaciswa.Ngokwesibonelo, ku-polymer eyodwa, I-MFR: 12 noma ngaphezulu ingasetshenziselwa okujwayelekileimikhiqizo yomjovo, ingasetshenziselwa ukukhiqizwa kwemicu ye-multifilament, futhi ingenziwa ngokukhethekile ukuze inikeze ukusabalalisa kwesisindo se-molecular ebanzi ukuze kuthuthukiswe ukucutshungulwa kwengxenye yangemuva ye-fiber weaving. ukwandisa ukuvulwa ukuze kuhlangatshezwane nezidingo zeisikhwama sepulasitikiimikhiqizo.
1. Izinga elijwayelekile (Homopolymer)
I-monopolymer, noma i-homopolymer, yimpahla eluhlaza lapho i-propylene ehlanzekile yenziwa i-polymerized.
2. I-COPOLYMER Enomthelela
Uma i-polymer eyodwa yengezwa ngerabha ye-ethylene propylene, amandla omthelela ngokuyinhloko ancike kokuqukethwe kwerabha, futhi ukumelana nokubanda kuncike ikakhulukazi kokuqukethwe kwe-ethylene.Abakhiqizi bezinto eziluhlaza abahlukene bacubungula ngokuhlukile, okuqukethwe okuphezulu kwe-ethylene nakho kuhlukile.
3. Ama-isotacite aphezulu noma I-CRISTALLINITY ELIPHEZULU
Nciphisa okuqukethwe kwesakhiwo sokuhlukanisa ku-polymer ye-PP, ukwanda okuhlobene kokuqukethwe kwesakhiwo esivamile, futhi kuthuthukise i-crystallinity.Ithuthukisa ngokuyinhloko ukuqina, izinga lokushisa lokushisa okushisayo, ukuqina kobuso, ukumelana nokuklwebha kanye nokucwebezela kwezinto ezingavuthiwe.Yebo, ukungezwa i-nucleating agent izophinde ibe nomthelela ekuthuthukisweni kwalezi zakhiwo ezingenhla.
4. I-COPOLYMER engahleliwe
I-copolymerization engahleliwe i-propylene ne-ethylene copolymerization.I-Ethylene ihlakazeke ngendlela engafanele ku-polymer, enciphisa ngokuyinhloko i-crystallinity ye-polymer futhi ithuthukise ukucaca.
5. I-Terpolymer
Ingabe isandiso se-polymer engahleliwe, ngokuvamile iqukethe i-propylene ethylene (EPR) amazinga aphezulu kakhulu ku-3.5%, kodwa kukhona inqubo engangezwa ku-5%, nokuqukethwe kwe-ethylene ephakeme emkhiqizweni okuthambile, izinga lokushisa lokushintsha okushisayo, ukuthambisa. iphuzu, ukwehlisa izinga lokushisa lokuvalwa kokushisa, ngezinye izikhathi ukuze kwandiswe okuqukethwe kwe-ethylene ngosizo lwe-butadiene noma ezinye izithako zesithathu ziba i-polymer emithathu evamile, ukuze kuzuzwe izidingo zempahla ebonakalayo engenhla.
6. Ibanga lengxubevange
Ingxube yezinto zokusetshenziswa kwepulasitiki ehlukene enenani eliphakeme ingachazwa njengebanga le-alloy.Isibonelo, i-PP engezwe nge-LDPE ingathuthukisa ukuthambile namandla okuthinta, futhi inganciphisa ukugoqa futhi ikhulise ukushelela ekucutshungulweni.Ekubumbeni, kungase futhi kunciphise ukwenzeka kwezinto ezibonakalayo.PP kanye ne-EPR kanye ne-HDPE kungagcina ukuqina, kunciphise into emhlophe ebangelwa okuqukethwe okuphezulu kwe-EPR, futhi kuthuthukise amandla omthelela.
7.Ukuhlanganisa
Ukuxuba izinto ezahlukene
