Mokhoa oa tlhahiso ea rabara
Rubber ke thepa e otlolohileng eo hangata e nkiloeng ho latex ea lifate tsa rabara kapa mehloli ea maiketsetso. E bonts'a elasticity e ntle haholo, ho hanyetsa abrasion, le ho hanyetsa botsofali, ho e etsa hore e sebelisoe haholo lits'ebetsong tse fapaneng tse kang ho etsa mabili, litiiso, liphaephe, lipampiri tsa rabara le tse ling. Ts'ebetso ea tlhahiso ea lihlahisoa tsa rabara hangata e kenyelletsa mehato e mengata ea bohlokoa ea ts'ebetso e joalo ka mastication, compounding, calendering, extrusion, molding, le vulcanization. Mohato o mong le o mong o na le karolo ea bohlokoa ho khethollang ts'ebetso le boleng ba lihlahisoa tsa ho qetela. Ka tlaase mona ke tlhaloso e qaqileng ea mokhoa oa ho etsa lihlahisoa tsa rabara.
1. Mastication:
Rabara e tala le li-additives li kopantsoe 'me li futhumatsoa ka har'a rabara ho nolofatsa rabara, ho matlafatsa ho khomarela, le ho tlosa litšila tse teng ho eona.
Lintlha tsa Bohlokoa: Taolo ea nako, mocheso, matla a mochini, le mefuta / boholo ba lisebelisoa tsa ho masticating.
2. Ho kopanya:
Ka har'a motsoako, rabara le li-additives tse fapa-fapaneng (tse kang li-vulcanization agents, li-anti-aging agents, li-fillers, joalo-joalo) li kopantsoe ka mokhoa o ts'oanang ho ntlafatsa ts'ebetso ea lihlahisoa tsa rabara.
Lintlha tsa Bohlokoa: Mofuta, tekanyo, le tatellano ea li-additives, mocheso o kopanyang le nako, matla a ho kopanya, har'a tse ling.
3. Khalendara:
Rabara e tsoakiloeng e hatelloa ka maqephe a tšesaane kapa lihlopha tse tšesaane ka mochine oa calender bakeng sa ts'ebetso e latelang le ho bōptjoa.
Lintlha tsa Bohlokoa: Taolo ea mocheso oa khalendara, lebelo, khatello, boima ba rabara le viscosity.
4. Extrusion:
Rabara e fetisoa ke mochine oa extrusion hore e be lihlahisoa tse tsoelang pele tse nang le sebopeho se itseng sa sefapano, se sebelisetsoang ho etsa lihlahisoa tsa rabara ka li-tubes, lithupa kapa libopeho tse ling tse rarahaneng.
Lintlha tsa bohlokoa: Taolo ea mocheso oa mochini oa extrusion, khatello, lebelo, moralo oa hlooho ea lefu, jj.
5. Ho Bopa:
Thepa ea rabara e kenngoa ka har'a hlobo, 'me tlas'a ketso ea ho futhumatsa le khatello, e tlatsa sekoti sa hlobo ebe e fumana sebopeho se batlang.
Lintlha tsa Bohlokoa: Moralo oa hlobo, mocheso, khatello, taolo ea nako, palo ea tlatsetso ea rabara le thepa ea phallo.
6. Vulcanization:
Lihlahisoa tsa rabara tse entsoeng li behiloe ka sebōping sa vulcanization, 'me karabelo ea vulcanization e etsoa tlas'a mocheso o itseng, nako le khatello, e le hore limolek'hule tsa rabara li hokahane, ka hona li ntlafatsa matla a mochine, ho apara ho hanyetsa le ho hanyetsa botsofali. rabara.
Lintlha tsa Bohlokoa: Taolo ea mocheso oa vulcanization, nako, khatello, mofuta / boholo ba moemeli oa vulcanizing, le sekhahla sa lihokelo le sebopeho.
Tlhaloso e qaqileng e ka holimo e hlalosa mehato ea bohlokoa ea ts'ebetso tlhahisong ea lihlahisoa tsa rabara, 'me mohato o mong le o mong ts'ebetso e nepahetseng le taolo li bohlokoa ho khetholla boleng le ts'ebetso ea lihlahisoa tsa ho qetela tsa rabara.
