Umphumela we-vulcanization esakhiweni nasezimpahleni zerabha

Umphumela we-vulcanization esakhiweni nasezimpahleni:

Enqubweni yokukhiqizwa kwemikhiqizo yerabha, i-vulcanization yisinyathelo sokugcina sokucubungula. Kule nqubo, irabha idlula ochungechungeni lwezimo zamakhemikhali eziyinkimbinkimbi, ezishintsha kusuka esakhiweni esiqondile kuya esakhiweni esinomzimba, zilahlekelwa ukuqina kwerabha exubile futhi zibe nokunwebeka okuphezulu kwerabha exhumene, ngaleyo ndlela zithole izakhiwo ezinhle kakhulu zomzimba nezomshini, ukumelana nokushisa Ukusebenza, ukumelana nesinyibilikisi kanye nokumelana nokugqwala kuthuthukisa inani lokusetshenziswa kanye nobubanzi bokusetshenziswa kwemikhiqizo yerabha.

Ngaphambi kokwenziwa kwe-vulcanization: isakhiwo esiqondile, ukusebenzisana phakathi kwama-molecule ngamandla ka-van der Waals;

Izakhiwo: ukuqina okukhulu, ukunwebeka okuphezulu, kanye nokuncibilika;

Ngesikhathi sokuqhuma kwe-vulcanization: i-molecule iyaqaliswa, bese kwenzeka ukusabela kokuxhumanisa kwamakhemikhali;

Ngemva kokuhlanganiswa kwe-vulcanization: isakhiwo senethiwekhi, esiphakathi kwama-molecule anezibopho zamakhemikhali;

Isakhiwo:

(1) Isibopho samakhemikhali;

(2) Indawo yesibopho esixhumanisayo;

(3) Izinga lokuxhumanisa;

(4) Ukuxhumanisa;

Izakhiwo:

(1) Izakhiwo zemishini (amandla okunwebeka njalo. Ubulukhuni. Amandla okunamathela. Ukwelula. Ukunwebeka);

(2) Izakhiwo ezibonakalayo

(3) Ukuqina kwamakhemikhali ngemva kokuguqulwa kwe-vulcanization;

Izinguquko ezimpahleni zerabha:

Uma sithatha irabha yemvelo njengesibonelo, ngokwanda kwezinga lokwakheka kwe-vulcanization;

(1) Izinguquko ezimpahleni zomshini (ukunwebeka. Amandla okudabuka. Amandla okude. Amandla okudabuka. Ubulukhuni) ukwanda (ukude. Isethi yokucindezela. Ukukhiqizwa kokushisa kokukhathala) kwehla

(2) Izinguquko ezimpahleni zomzimba, ukungena komoya kanye nokungena kwamanzi kwehla, azikwazi ukuncibilika, zivuvukala kuphela, zithuthukisa ukumelana nokushisa

(3) Izinguquko ekuzinzeni kwamakhemikhali

Ukuqina kwamakhemikhali okwandisiwe, izizathu

a. Ukusabela kokuxhumanisa kwenza amaqembu noma ama-athomu asebenzayo ngamakhemikhali angabe esakhona, okwenza kube nzima ukuthi ukusabela kokuguga kuqhubeke

b. Isakhiwo senethiwekhi sivimbela ukusabalala kwama-molecule aphansi, okwenza kube nzima ngama-radical enjoloba ukusabalalisa

Ukukhethwa Nokunqunywa Kwezimo Zokuvunguza Kwenjoloba

1. Ingcindezi ye-Vulcanization

(1) Kudingeka kusetshenziswe ingcindezi lapho imikhiqizo yerabha ivundiswa. Inhloso ukwenza lokhu:

a. Vimbela irabha ekukhiqizeni amabhamuza futhi uthuthukise ukuqina kwerabha;

b. Yenza izinto zerabha zigeleze bese ugcwalisa isikhunta ukuze wenze imikhiqizo ngamaphethini acacile

c. Thuthukisa ukunamathelana phakathi kwesendlalelo ngasinye (isendlalelo esinamathelayo kanye nesendlalelo sendwangu noma isendlalelo sensimbi, isendlalelo sendwangu kanye nesendlalelo sendwangu) kumkhiqizo, futhi uthuthukise izakhiwo zomzimba (njengokumelana nokuguquguquka) kwe-vulcanizate.

(2) Ngokuvamile, ukukhethwa kwengcindezi ye-vulcanization kufanele kunqunywe ngokuya ngohlobo lomkhiqizo, ifomula, i-plasticity nezinye izici.

(3) Ngokuyisisekelo, imithetho elandelayo kufanele ilandelwe: i-plasticity inkulu, ingcindezi kufanele ibe ncane; ukujiya komkhiqizo, inani lezingqimba, kanye nesakhiwo esiyinkimbinkimbi kufanele kube kukhulu; ingcindezi yemikhiqizo emincane kufanele ibe ncane, futhi ngisho nengcindezi evamile ingasetshenziswa

Kunezindlela eziningana zokucindezela kanye nokucindezela:

(1) Iphampu ye-hydraulic idlulisela ingcindezi kwisikhunta nge-flat vulcanizer, bese idlulisela ingcindezi kwi-compound yerabha esuka kwisikhunta

(2) Icindezelwa ngqo yi-vulcanizing medium (njengomusi)

(3) Ukucindezela umoya ocindezelwe

(4) Ukujova ngomshini wokujova

2. Izinga lokushisa le-Vulcanization kanye nesikhathi sokwelapha

Izinga lokushisa le-vulcanization liyisimo esiyisisekelo kakhulu sokusabela kwe-vulcanization. Izinga lokushisa le-vulcanization lingathinta ngqo ijubane le-vulcanization, ikhwalithi yomkhiqizo kanye nezinzuzo zezomnotho zebhizinisi. Izinga lokushisa le-vulcanization liphezulu, ijubane le-vulcanization liyashesha, futhi ukusebenza kahle kokukhiqiza kuphezulu; ngaphandle kwalokho, ukusebenza kahle kokukhiqiza kuphansi.

Ukwandisa izinga lokushisa le-vulcanization kungabangela izinkinga ezilandelayo;

(1) Kubangela ukuqhekeka kochungechunge lwama-molecule enjoloba kanye nokuguqulwa kwe-vulcanization, okuholela ekunciphiseni kwezakhiwo zemishini zenhlanganisela yenjoloba.

(2) Yehlisa amandla ezindwangu emikhiqizweni yerabha

(3) Isikhathi sokusha kwenhlanganisela yerabha siyafinyezwa, isikhathi sokugcwalisa siyancishiswa, futhi umkhiqizo awunayo ingxenye yeglue.

(4) Ngoba imikhiqizo ewugqinsi izokwandisa umehluko wokushisa phakathi kwangaphakathi nangaphandle komkhiqizo, okuholela ekuvuvukeni okungalingani
