Lihlahisoa tsa rabara li thehiloe ho rabara e tala 'me li eketsoa ka bongata bo loketseng ba metsoako e kopanyang. …
1.Rabara ea tlhaho kapa ea maiketsetso ntle le metsoako e kopanyang kapa ntle le vulcanization e bitsoa rabara e tala. Rabara ea tlhaho e na le thepa e ntle e felletseng, empa tlhahiso ea eona e ke ke ea fihlela litlhoko tsa indasteri, leha e le hore e ka fihlela litlhoko tse ling tse khethehileng tsa ts'ebetso, kahoo ho na le lits'ebetso tse ngata tsa rabara ea maiketsetso. …
Sehlahisoa sa ho kopanya E le ho ntlafatsa le ho ntlafatsa litšobotsi tse fapaneng tsa lihlahisoa tsa rabara, ntho e ekelitsoeng e bitsoa sehlahisoa sa ho kopanya. Sehlahisoa sa ho kopanya se kenyelletsa meutloa ea vulcanization, li-filler, li-accelerator tsa vulcanization, li-plasticizer, li-anti-botsofali le li-agent tse foufatsang.
① Karolo ea moemeli oa vulcanizing e tšoana le moemeli oa ho folisa polasetiking ea thermosetting. E etsa hore liketane tsa limolek'hule tsa rabara li thehe liketane tse otlolohileng, tse hokahaneng ka nepo, 'me e be sebopeho sa marang-rang, ka hona li ntlafatsa thepa ea mechini le ea 'mele ea rabara. Sulfide e sebelisoang hangata ke sebabole le sulfide. …
② Setlatsetso se reretsoe ho ntlafatsa thepa ea mechini ea rabara, joalo ka matla, ho thatafala, ho hanyetsa ho tsofala le ho tiea. Litlatsetso tse sebelisoang haholo ke carbon black le masela, likhoele, esita le lithapo tsa tšepe kapa li-braids tsa tšepe e le thepa ea foreimi. Ho eketsa li-filler ho ka boela ha fokotsa bongata ba rabara e tala le ho fokotsa litšenyehelo tsa rabara. …
③ Lisebelisoa tse ling tse kopanyang li-accelerator tsa vulcanization li ka potlakisa ts'ebetso ea vulcanization le ho ntlafatsa phello ea vulcanization; li-plasticizer li sebelisoa ho eketsa plasticity ea rabara le ho ntlafatsa ts'ebetso ea ts'ebetso ea ho bopa; li-antioxidants (li-antioxidants) li sebelisoa ho thibela kapa ho liehisa botsofali ba rabara.
2.Likarolo le lits'ebetso tsa lihlahisoa tsa rabara
Lihlahisoa tsa rabara li na le litšobotsi tsa ho tenyetseha ho hoholo, ho mamella ho hoholo, matla a hodimo le ho hanyetsa ho tlola ho hoholo. Modulus ea eona e tenyetsehang e tlase haholo, ke 1-10 MPa feela, 'me phetoho ea eona e tenyetsehang e kholo haholo, ho fihlela ho 100% ho isa ho 1000%. E na le ho tenyetseha ho hoholo le bokhoni ba ho boloka matla. Ho phaella moo, e na le ho hanyetsa ho tlola ho hoholo, ho thibela molumo, ho damping le ho thibela ho tlola. Leha ho le joalo, rabara e na le ho hanyetsa mocheso ho fokolang le ho hanyetsa serame (e khomarela mochesong o phahameng, e robeha ha e pepesehetse serame), 'me e tla qhibiliha ka har'a li-solvents. …
Indastering, rabara e ka sebelisoa ho etsa mabili, litiiso tse sa fetoheng le tse feto-fetohang, likarolo tse thibelang ho thothomela le tse thibelang ho thothomela, mabanta a phetisetso, mabanta a tsamaisang le liphaephe, lithapo, likhoele, thepa ea ho thibela motlakase le likarolo tsa brake.
