Njengohlobo lwenjoloba olungewona ama-polar nge-chain enkulu egcwele, i-ethylene propylene rubber inokusebenza okuhle kakhulu ekumelaneni kwesimo sezulu, ukumelana nemidiya ye-polar, ukumelana nokuguga, ukumelana namabanga amaningi enjoloba ye-ethylene propylene. Kodwa-ke, kunamabanga amaningi enjoloba ye-ethylene propylene, amamaki ahlukene wenjoloba e-ethylene propylene enobuchwepheshe be-ethylene ybrene ruble irobi njo okusetshenziswa kakhulu embonini esetshenziswa kakhulu embonini kokuqukethwe kwe-ethylene, okuqukethwe kwesithathu kwe-monomer kanye ne-money viscosity ekwenzeni okuqukethwe. Kwenziwe ucwaningo oluthile, olunokubaluleka okuthile okuqondisayo.
Ngokuthuthukiswa kobuchwepheshe kanye nomphakathi, ukufunwa kwabantu kwemikhiqizo ekhanyayo kuyanda, imikhiqizo enjoloba ekhanyayo futhi enemibala ingangena kancane kancane, i-agent enkulu yokuqinisa imikhiqizo yenjoloba ekhanyayo idlala indima ebaluleke kakhulu.
Njengomenzeli wokuqinisa ikakhulukazi esetshenziswa yimikhiqizo enjoloba ekhanyayo ekhanyayo, i-silica idlala indima ebaluleke kakhulu.

Ukusebenza kwe-Vulcan kwe-ethylene propylene ruble
Umphumela wokuqukethwe kwe-ethylene kokushiswa ngesikhathi (TC10) futhi ucubungule icebo le-ethylene propylene ruble.
(Umphumela wokuqukethwe kwe-ethylene ngesikhathi sokuphequlula kwe-ethylene propylene rubber (TC10) isikhathi sokuvuselela (i-TC90) sinciphile kancane kancane, okuqukethwe kwe-TC10 kwe-ethylene kuncane, okuqukethwe kwe-TC10, lapho okuqukethwe kusondele kokuqukethwe okufanayo kwe-ethylene noma okufanayo, kwehlise okuqukethwe okwelwesithathu monomer, imfushane i-TC10 ne-TC90; I-torque encane (ml) yezinto ezibonakalayo, kwehlisa okuqukethwe kwe-monomer yesithathu.
I-torque ephansi (ml) yalokhu kuthinteka kakhulu kokuqukethwe kwe-ethylene, okuphezulu okuqukethwe kwe-ethylene, okubangelwa ukuhamba kwe-polcani, ngoba i-torque yerabha ibuye ikhuphuke kancane kancane, okuqukethwe kwesithathu kwe-monomes ku-modulus. Ukulingana okuhle nokunikela kokuqukethwe kwesithathu kwe-monomer kukhuphuka okuqukethwe okuqukethwe, kukhulu i-modulus yezinto ezibonakalayo, kukhulu modulus wezinto ezibonakalayo. Ngokuqukethwe okufanayo noma okufanayo kwe-ethylene, kuphakama okuqukethwe kwesithathu kwe-monomer, kuphakama i-modulus. Umehluko phakathi kwe-torque ephezulu kakhulu kanye ne-torque ephansi (i-MH -ML) isetshenziselwa ukwenza iziqu zokuxhumanisa okuxhumeka kwerabha, futhi kungabonakala ukuthi okuqukethwe kwe-ethylene kanye nokuqukethwe okuphezulu kwe-monomer yesithathu, okuphezulu okuphezulu kwe-monomer yesithathu, kukhuphuka ngezinga elikuxhumanisayo.
Izici ezi-2 zemishini yocwaningo lwe-ethylene proplene ruble rubber
Ubulukhuni benjoloba buthinteka kakhulu kokuqukethwe kwe-ethylene, okuphezulu okuqukethwe kwe-ethylene, kuphakama ubulukhuni benjoloba, okuqukethwe kwesithathu kwe-monomer kunomthelela omncane ngobulukhuni; Amandla ashubile wezinto ezibonakalayo kanye namandla ezinyathelayo yi-Ethylene kusobala, ngokwanda kokuqukethwe kwe-ethylene, amandla okuqukethwe akhuphukile kancane, lapho amandla okuqukethwe akhuphukile, okuphezulu kwawo mandla, akhuphuka mandla ashubile Amandla, akhuphuka amandla ashubile athe xaxa, akhuphuka amandla ashubile kanye nokuqina kwezinyembezi. Ngokufanayo, okuphezulu kwe-monomer yesithathu, kukhuphuka amandla ashukumisayo kanye nokuqina kwezinyembezi zezinto ezibonakalayo, okukhombisa ukuthi okuqukethwe kwe-ethylene kanye nokuqukethwe kwe-monomer yesithathu emandleni omphumela we-pernergistic; okuqukethwe kwe-ethylene kanye nokuqukethwe kwesithathu kwe-monomer yokucindezela okubonakalayo kuyafana nomthelela emandleni okuqukethwe, okuphezulu kokuqukethwe kwe-ethylene kwezinto ezibonakalayo, okuphezulu kokuqukethwe kwe-monomer yesithathu ngokugcwele; Okuqukethwe kwe-ethylene kokubukwa okuthe xaxa komphumela omncane, ngaphakathi kohlu oluthile lokugcwaliseka okuthe xaxa kwezinto zokwanda kokuqukethwe kwe-ethylene, iphuzu elithile, amandla athile okuqukethwe kukhula kancane, kukhuphuka okuqukethwe kwesithathu kwe-monomer. Ngaphakathi kwebanga elithile, ukugcwala kwekhefu kukhuphuka kancane kancane ngokwanda kokuqukethwe okususelwa ku-ethylene, bese kuqala ukwehlisa kancane ngemuva kokushintshwa kwe-excation, okuqukethwe okufanayo noma okuqukethwe kwe-ethylene okususelwa ku-ethylonger, kukhula okukhulu kakhulu kokuqhekeka kokungephulwa kwekhefu lokuqukethwe; Ukusebenza kwe-abrasion kwezinto ezibonakalayo kunobulukhuni obukhulu nobulukhuni bayo, ngokuvamile, kukhuluma ubunzima namandla, umthamo we-abrasion buzoba mncane ngokufanele, futhi ukusebenza kwegciwane kuzoba ngcono; Njengoba okuqukethwe okususelwa ku-ethylene kukhuphuka, kunobudlelwano obuthile phakathi kobulukhuni namandla nokusebenza kwe-abrasion kwezinto. Ubulukhuni obungokwenyama namandla anokukhuphuka okuthile, umthamo ohlukumezayo wehla kancane kancane, izinhlangothi zombili ze-monomer yesithathu zizothinta nenqubo yokuqukethwe kwe-monomer, kodwa kuqhathaniswa nomphumela wokuqukethwe kwe-ethylene, okuqukethwe kwe-monomer yesithathu kunethonya eliphansi kwizakhiwo zalo ezixakile.
3 Ukwenza Okungamelana Nama-Air Ager Agerant Air Agerant
Kuyabonakala ukuthi, ngemuva kokuguga ngo-160 ℃ ngo-24h, ubulukhuni bezinto ezibonakalayo buncane kakhulu, ukucindezelwa okuqhubekayo okuthe xaxa kukhuphuka kancane, amandla okugcinwa kuwo ancipha kancane, izinga lokugcina elibunjiwe lihlale liphezulu, futhi izinga lokugcina eliphakeme liphunyela kancane; Lokhu kungenxa yokuthi injoloba ye-ethylene-proppene yirabha enochungechunge oluyinhloko olubanzi, olunokumelana nokuguga okunamandla okuguga okunamandla. Ngenxa yokumelana nokuguga komoya okushisayo kwe-ethylene propylene rubber, kunzima ukukhombisa umphumela wokuqukethwe kwe-ethylene nokuqukethwe kwesithathu kokusebenza kokuguga kokuguga okufushane kokuguga komoya okushisayo.
4 ehlukile ethylene proppene rain ukumelana nokushisa okuphansi okuphansi
Ngokukhuphuka kokuqukethwe kwe-ethylene, ukumelana kwezinga lokushisa okuphansi kokuqukethwe kwehla kancane kancane.
Ngokukhuphuka kokuqukethwe kwe-ethylene, ukumelana okuphansi kwezinga lokuqukethwe kuwohloka kancane kancane, okuqukethwe okufanayo noma okufanayo, okungukuqukethwe kwe-ethylene purlene rubber kwalapho, lokhu kungukuphakamisa ama-macromolececes ku-crystallize kancane kuyakhuphuka kancane kancane [10]. Ukwanda kwekhono le-crystallization kuzoholela ekwandeni kobulukhuni namandla ento, kepha futhi kunciphisa ukuguquguquka kwamaketanga amangqamuzana awonke, ukuze ukumelana nezinga lokushisa okuphansi kwentokozo. Lapho okuqukethwe kweqembu le-Ethylene kusondelene, okuqukethwe okuphansi kwe-monomer yesithathu kuzoholela ezingeni eliphansi lokuxhumanisa okuqukethwe, okuzokwandisa ukuguquguquka kwe-molecule konke, futhi kuthuthukise ukumelana nokushisa okuphansi kwezinto ezibonakalayo.
