Lihlahisoa tsa rabara li thehiloe holim'a rabara e tala 'me li eketsoa ka bongata bo loketseng ba metsoako. …
1.Rabara ea tlhaho kapa ea maiketsetso ntle le li-agent kapa ntle le vulcanization e bitsoa rabara e tala. Rabara ea tlhaho e na le litšobotsi tse ntle tse akaretsang, empa tlhahiso ea eona e ke ke ea finyella litlhoko tsa indasteri, ebile e ke ke ea finyella litlhoko tse khethehileng tsa ts'ebetso, kahoo ho na le lisebelisoa tse ngata tsa rabara ea maiketsetso. …
Motsoako oa motsoako Bakeng sa ho ntlafatsa le ho ntlafatsa thepa e fapaneng ea lihlahisoa tsa rabara, ntho e ekelitsoeng e bitsoa motsoako oa motsoako. Lisebelisoa tse kopanyang haholo-holo li kenyelletsa meutloa ea vulcanization, li-filler, li-accelerator tsa vulcanization, li-plasticizers, li-anti-aging le li-accelerator.
① Karolo ea moemeli oa vulcanizing e ts'oana le e phekolang ka har'a polasetiki ea thermosetting. E etsa hore liketane tsa limolek'hule tsa rabara li thehe liketane tse rapameng, li hokahane ka nepo, 'me li fetohe sebopeho sa marang-rang, ka hona ho ntlafatsa thepa ea mochini le ea 'mele ea rabara. Sulfide e sebelisoang hangata ke sebabole le sulfide. …
② Filler ke ho ntlafatsa thepa ea mochini ea rabara, joalo ka matla, boima, ho hanyetsa le ho tiea. Li-filler tse sebelisoang haholo ke carbon black le masela, likhoele, esita le lithapo tsa tšepe kapa li-braids tsa tšepe e le lisebelisoa tsa moralo. Ho eketsa li-filler le hona ho ka fokotsa palo ea rabara e tala le ho fokotsa litšenyehelo tsa rabara. …
③ Lisebelisoa tse ling tse kopanyang vulcanization accelerators li ka potlakisa ts'ebetso ea vulcanization le ho ntlafatsa phello ea vulcanization; li-plasticizers li sebelisoa ho eketsa polasetiki ea rabara le ho ntlafatsa ts'ebetso ea ho bopa; li-antioxidants (antioxidant) li sebelisoa ho thibela kapa ho liehisa botsofali ba rabara.
2.Likarolo le ts'ebeliso ea lihlahisoa tsa rabara
Lihlahisoa tsa rabara li na le litšoaneleho tsa elasticity e phahameng, botsitso bo phahameng, matla a phahameng le khanyetso e phahameng ea ho apara. Modulus ea eona ea elastic e tlase haholo, ke 1-10 MPa feela, 'me deformation ea eona ea elastic e kholo haholo, ho fihla ho 100% ho isa ho 1000%. E na le matla a ho tenyetseha le matla a ho boloka matla. Ho phaella moo, e na le khanyetso e ntle ea ho apara, ho thibela molumo, ho senya le ho pata. Leha ho le joalo, rabara e na le ho hanyetsa mocheso o fokolang le ho hanyetsa serame (e khomarelang mocheso o phahameng, e brittle ha e le tlas'a serame), 'me e tla qhibiliha ka har'a metsoako. …
Indastering, rabara e ka sebelisoa ho etsa lithaere, litiiso tse tsitsitseng le tse matla, li-vibration damping le likarolo tse thibelang ho sisinyeha, mabanta a phetiso, mabanta a tsamaisang liphaephe le liphaephe, lithapo, lithapo, lisebelisoa tsa ho kenya motlakase le likarolo tsa mariki.
