Theknoloji ea ho sebetsana le rabara e hlalosa mokhoa oa ho fetola lisebelisoa tse bonolo tse tala lihlahisoa tsa rabara tse nang le thepa le libopeho tse itseng. Litaba tsa mantlha li kenyelletsa:
- Sistimi ea ho kopanya rabara:
Mokhoa oa ho kopanya rabara e tala le li-additives ho latela litlhoko tsa ts'ebetso ea sehlahisoa, ho nahanoa ka lintlha tse kang ts'ebetso ea theknoloji ea ho sebetsa le litšenyehelo. Tsamaiso e akaretsang ea khokahanyo e kenyelletsa rabara e tala, tsamaiso ea vulcanization, tsamaiso ea matlafatso, tsamaiso ea tšireletso, tsamaiso ea plasticizer, joalo-joalo Ka linako tse ling e boetse e kenyelletsa mekhoa e meng e khethehileng e kang lelakabe la mollo, mebala, foaming, anti-static, conductive, joalo-joalo.
1) Rabara e tala (kapa e sebelisoang hammoho le li-polymers tse ling): thepa ea motsoali kapa thepa ea matrix
2) Sistimi ea Vulcanization: Sistimi e sebetsanang le lik'hemik'hale le li-macromolecules tsa rabara, ho fetola rabara ho tloha ho li-macromolecules tse melang ho ea sebopeho sa marang-rang a mahlakore a mararo, ho ntlafatsa thepa ea rabara le ho tsitsisa morphology ea eona.
3) Sistimi ea ho tlatsa matlafatso: Ho eketsa lisebelisoa tse matlafatsang joalo ka carbon black kapa li-fillers tse ling ho rabara, kapa ho ntlafatsa thepa ea eona ea mochini, ho ntlafatsa ts'ebetso ea ts'ebetso, kapa ho fokotsa litšenyehelo tsa sehlahisoa.
4) Sistimi ea ts'ireletso: Eketsa li-agent tse thibelang botsofali ho liehisa botsofali ba rabara le ho ntlafatsa bophelo ba litšebeletso tsa lihlahisoa.
5) Sistimi ea polasetiki: e fokotsa boima ba sehlahisoa le viscosity ea rabara e tsoakiloeng, 'me e ntlafatsa ts'ebetso ea ts'ebetso.
- Theknoloji ea ho lokisa rabara:
Ho sa tsotellehe hore na ke sehlahisoa sefe sa rabara, se tlameha ho feta ka mekhoa e 'meli: ho kopanya le ho senya. Bakeng sa lihlahisoa tse ngata tsa rabara, tse kang li-hoses, litheipi, lithaere, joalo-joalo, li boetse li hloka ho feta ka mekhoa e 'meli: ho roala le ho phalla. Bakeng sa rabara e tala e nang le viscosity e phahameng ea Mooney, e boetse e hloka ho bōptjoa. Ka hona, ts'ebetso ea mantlha le ea bohlokoa ka ho fetesisa ts'ebetsong ea rabara e kenyelletsa mekhahlelo e latelang:
1) Ho hloekisa: ho fokotsa boima ba limolek'hule tsa rabara e tala, ho eketsa polasetiki, le ho ntlafatsa ts'ebetso.
2) Ho kopanya: Kopanya likarolo tsohle ka mokhoa o ts'oanang ho etsa rabara e tsoakiloeng.
3) Ho roala: Mokhoa oa ho etsa lihlahisoa tse felileng ka mokhoa o itseng ka ho kopanya rabara kapa ho sebelisa lisebelisoa tsa skeleton tse kang masela le lithapo tsa tšepe ka ho hatella, ho bopa, ho kopanya, ho hlakola le ho kopanya.
4) Ho hatella: Mokhoa oa ho hatella lihlahisoa tse felileng ka likarolo tse fapaneng tse fapaneng, joalo ka li-tubes tse ka hare, maoto, mabota le li-hose tsa rabara, ho tsoa ho rabara e tsoakiloeng ka sebopeho sa molomo.
5) Vulcanization: Mohato oa ho qetela oa ts'ebetso ea rabara, e kenyelletsang karabelo ea lik'hemik'hale ea li-macromolecules tsa rabara ho hlahisa li-cross-link ka mor'a mocheso o itseng, khatello le nako.
