Umphumela we-Vulcanization ngesakhiwo nezakhiwo:
Enqubweni yokukhiqiza yemikhiqizo yenjoloba, i-vulcanization yisinyathelo sokugcina sokucubungula. Kule nqubo, irabha lithola uchungechunge lokuphendula okuyinkimbinkimbi kwamakhemikhali, ishintsha kusuka esakhiweni esinomugqa ohlelweni olubunjiwe emzimbeni, ngaleyo ndlela sithola ukumelana okuphezulu kwenjoloba, ukumelana nokuqina kokuqina kanye nokuphikiswa kokugqwala nokuqina kokugqwala kuthuthukise inani lokusetshenziswa kanye nohlelo lokusebenza lwemikhiqizo yenjoloba.
Ngaphambi kokuvuselela: Ukwakheka okuqondile, ukusebenzisana kwama-intermolecular ngeVan der Waals Force;
Izakhiwo: I-Plastic Great, ukunwebeka okuphezulu, kanye ne-solubility;
Nge-Vutecanization: I-molecule iyasungulwa, futhi kwakha ukusabela okuxhumeka kwamakhemikhali;
Ngemuva kokuvuselela: Isakhiwo senethiwekhi, i-intermoletular enamabhondi wamakhemikhali;
Isakhiwo:
(1) isibopho samakhemikhali;
(2) Isikhundla sesibopho esixhumanisayo;
(3) degree lokuxhumanisa;
(4) Ukuxhumanisa; .
Izakhiwo:
(1) Izakhiwo zemishini (amandla ahlala njalo. Ubulukhuni. Amandla ashubile. Ukugcwala. Ukuqina);
(2) Izakhiwo ezibonakalayo
(3) ukuqina kwamakhemikhali ngemuva kokuvuselela;
Izinguquko ezeza ngezakhiwo zenjoloba:
Ukuthatha irabha yemvelo njengesibonelo, ngokwanda kwezinga le-Vulcanization;
(1) Izinguquko ezeza ngezakhiwo zemishini (ukuqina. Amandla. Amandla abuhlungu
.
(3) Izinguquko ekuzinyokeni kwamakhemikhali
Ukukhulisa ukuqina kwamakhemikhali, izizathu
a. Ukusabela okuxhumanisayo kwenza amaqembu amakhemikhali asebenzayo noma ama-athomu angasekho, okwenza kube nzima ngokusabela kokuguga ukuze uqhubeke
b. Ukwahlulela kwenethiwekhi kuvimbela ukuguquguquka kwama-molecule aphansi, okwenza kube nzima kuma-radicals werabha ukuze kuphazamise
Ukukhetha kanye nokunqunywa kwezimo ze-rubber Vulcanization
1. Ukucindezela Kwe-Vulcanization
(1) Ingcindezi idinga ukusetshenziswa lapho imikhiqizo yenjoloba i-Vulcanized. Inhloso ukuthi:
a. Vimbela irabha kusuka ekukhiqizeni ama-bubble futhi uthuthukise ukuhlanganiswa kwenjoloba;
b. Yenza izinto zenjoloba zigeleze futhi zigcwalise isikhunta ukwenza imikhiqizo ngamaphethini acacile
c. Thuthukisa ukunamathela phakathi kwesendlalelo ngasinye (ungqimba olunamathelane nendwangu noma ungqimba lwensimbi, ungqimba lwendwangu kanye nesendlalelo sendwangu) kumkhiqizo, futhi uthuthukise izakhiwo ezibonakalayo (njengokuphikiswa okuguqukayo) kwe-Vulcanzise.
(2) Ngokuvamile, ukukhethwa kwengcindezi ye-Vulcanization kufanele kunqunywe ngokuya ngohlobo lomkhiqizo, ifomula, i-plastikity kanye nezinye izinto.
(3) Umgomo, le mithetho elandelayo kufanele ilandelwe: i-plasticity inkulu, ingcindezi kufanele ibe yincane; Ubukhulu bomkhiqizo, inani lezendlalelo, nesakhiwo esiyinkimbinkimbi kufanele kube mkhulu; Ingcindezi yemikhiqizo emincane kufanele ibe yincane, futhi ingcindezi ejwayelekile ingasetshenziswa
Kunezindlela eziningana ze-Vulcanization kanye nokucindezela:
.
(2) ukucindezelwa ngqo ngobuso obuphakathi (njengomusi)
(3) acindezelwe umoya ocindezelwe
(4) umjovo ngumshini wokujova
2. Ukushisa kwe-Vulcanization kanye nesikhathi sokwelapha
Izinga lokushisa le-vulcanization liyisimo esiyisisekelo kunazo zonke sokusabela kwe-vulcanization. Izinga lokushisa le-Vulcanization lingathinta ngqo ijubane le-Vulcanization, ikhwalithi yomkhiqizo kanye nezinzuzo zezomnotho zebhizinisi. Izinga lokushisa le-vulcanization liphezulu, ijubane lokuvuselela ngokushesha, futhi ukusebenza kahle kokukhiqiza kuphezulu; Ngaphandle kwalokho, ukusebenza kahle kokukhiqiza kuphansi.
Ukwandisa izinga lokushisa le-vulcanization kungenza lezo zinkinga ezilandelayo;
.
(2) Yehlisa amandla ezindwangu emikhiqizweni yenjoloba
.
(4) Ngoba imikhiqizo emibi izokhulisa umehluko wokushisa phakathi kwangaphakathi nangaphandle komkhiqizo, okuholela ekuvuseleleni okungalingani
