1. Phallo ea motheo ea ts'ebetso
Ho na le mefuta e mengata ea lihlahisoa tsa rabara, empa mokhoa oa tlhahiso o tšoana hantle.Mokhoa oa motheo oa lihlahisoa tsa rabara tse nang le rabara e tloaelehileng ea rabara e tala e le lisebelisoa tse tala li kenyelletsa mekhoa e tšeletseng ea motheo: plasticizing, mixing, calendering, extrusion, molding le vulcanization.Ehlile, lits'ebetso tsa mantlha tse kang ho lokisa thepa e tala, ho qeta sehlahisoa, tlhahlobo le ho paka le tsona ke tsa bohlokoa.Theknoloji ea ho sebetsana le rabara ke haholo-holo ho rarolla ho hanyetsana pakeng tsa polasetiki le thepa ea elastic.Ka mekhoa e fapaneng ea mahlale, rabara ea elastic e fetoloa rabara e masticated ka polasetiki, ebe ho eketsoa lisebelisoa tse fapaneng ho etsa lihlahisoa tse felileng, ebe lihlahisoa tsa polasetiki tse felileng li fetoloa lihlahisoa tsa rabara tse nang le elasticity e phahameng, 'mele le mochini. thepa ka vulcanization.
2. Ho lokisetsa thepa e tala
Lihlahisoa tse ka sehloohong tsa lihlahisoa tsa rabara ke rabara e tala e le thepa ea motheo, 'me rabara e tala e bokelloa ka ho rema makhapetla a lifate tsa rabara tse hōlileng libakeng tsa tropike le tsa tropike.
Lisebelisoa tse fapaneng tse kopanyang ke lisebelisoa tse thusang tse kentsoeng ho ntlafatsa thepa ea lihlahisoa tsa rabara.
Lisebelisoa tsa fiber (k'hothone, hemp, boea le likhoele tse fapaneng tse entsoeng ke motho, likhoele tsa maiketsetso le lisebelisoa tsa tšepe, likhoele tsa tšepe) li sebelisoa e le lisebelisoa tsa marapo bakeng sa lihlahisoa tsa rabara ho matlafatsa matla a mochini le ho fokotsa ho senyeha ha sehlahisoa.Nakong ea ho lokisa thepa e tala, metsoako e tlameha ho lekanngoa ka nepo ho latela foromo.E le hore rabara e tala le motsoako oa motsoako o kopane ka homogeneously hammoho, thepa e hloka ho sebetsoa.Rabara e tala e lokela ho nolofatsoa ka phaposing ea ho omisa ka 60-70 ℃, ebe e khaola le ho robeha likotoana tse nyane.Motsoako oa motsoako o na le lumpy.Joalo ka parafine, asiti ea stearic, rosin, joalo-joalo ho siloa.Haeba phofo e na le litšila tsa mochini kapa likaroloana tse mahoashe, e hloka ho hlahlojoa ho tlosa metsi a kang pine tar le coumarone, tse hlokang ho futhumatsoa, ho qhibiliha, ho fetoha mouoane le ho sefshoa.Ho thehoa ha li-bubble nakong ea vulcanization e tšoanang ho ama boleng ba sehlahisoa.
3. Plasticizing
Rabara e tala e rekere 'me ha e na polasetiki e hlokahalang bakeng sa ts'ebetso, kahoo ha ho bonolo ho e sebetsa.E le hore u ntlafatse polasetiki ea eona, ho hlokahala hore u hlakole rabara e tala, e le hore moemeli oa motsoako o ka khona ho qhalakanngoa habonolo le ka mokhoa o ts'oanang ka rabara e tala nakong ea ho kopanya, 'me ka nako e ts'oanang, ho boetse ho thusa ho ntlafatsa ho phunyeletsa ha metsi. rabara le ho kenella ka har'a lesela la fiber nakong ea calendering le mokhoa oa ho etsa.le ho bopa mokelikeli.Mokhoa oa ho nyenyefatsa limolek'hule tsa ketane e telele tsa rabara e tala ho etsa polasetiki e bitsoa mastication.Ho na le mekhoa e 'meli ea ho etsa polasetiki ea rabara e tala: polasetiki ea mochini le polasetiki e futhumatsang.Mechanical mastication ke ts'ebetso eo ka eona limolek'hule tsa rabara tse telele li senyehang 'me li khutsufatsoa ho tloha boemong bo phahameng ba rekere ho ea boemong ba polasetiki ka extrusion ea mechine le ho ferekana ha polasetiki ka mocheso o tlaase.Plastiki e chesang ke ho fetisa moea o chesang o hatelitsoeng ka har'a rabara e tala tlas'a ts'ebetso ea mocheso le oksijene ho senya limolek'hule tsa ketane e telele le ho li khutsufatsa ho fumana polasetiki.
4.Ho kopanya
E le ho ikamahanya le maemo a fapaneng a ts'ebeliso, ho fumana thepa e fapaneng, 'me e le ho ntlafatsa ts'ebetso ea lihlahisoa tsa rabara le ho fokotsa litšenyehelo, li-agent tse fapaneng tsa motsoako li tlameha ho kenngoa ho rabara e tala.Ho kopanya ke mokhoa oo rabara e tala ea masticated e kopantsoeng le motsoako oa motsoako, 'me motsoako oa motsoako o qhalakantsoeng ka ho feletseng le ka mokhoa o ts'oanang ka rabara e tala ka ho kopanya mochine ka mochine oa ho kopanya rabara.Ho kopanya ke ts'ebetso ea bohlokoa ts'ebetsong ea tlhahiso ea lihlahisoa tsa rabara.Haeba ho kopanya ho sa tšoane, phello ea rabara le metsoako ea metsoako e ke ke ea etsoa ka botlalo, e amang ts'ebetso ea sehlahisoa.Thepa ea rabara e fumanoang ka mor'a ho kopanya e bitsoa rabara e tsoakiloeng.Ke thepa e feliloeng ka halofo ea ho etsa lihlahisoa tse fapaneng tsa rabara, tse tsejoang ka hore ke thepa ea rabara, eo hangata e rekisoang e le thepa.Bareki ba ka sebelisa thepa ea rabara ho e sebetsa ka kotloloho, ho e etsa le ho e kenya ka har'a lihlahisoa tse hlokahalang tsa rabara..Ho latela libopeho tse fapaneng, ho na le letoto la limaraka le mefuta e fapaneng e nang le thepa e fapaneng eo u ka khethang ho eona.
5.Ho theha
Ts'ebetsong ea tlhahiso ea lihlahisoa tsa rabara, mokhoa oa ho etsa libopeho le boholo bo fapaneng ka li-calender kapa li-extruders o bitsoa molding.
6.Vulcanization
Mokhoa oa ho fetola rabara ea polasetiki hore e be rabara ea rekere e bitsoa vulcanization.Ke ho eketsa tekanyo e itseng ea vulcanizing agent e kang sebabole, vulcanization accelerator, joalo-joalo Limolek'hule tsa linear tsa rabara e tala li hokahane ho ea ho tse ling ho etsa sebopeho sa marang-rang a mararo ka ho thehoa ha "marokho a sebabole", e le hore motsoako oa rabara oa polasetiki o fetohe vulcanizate e tsitsitseng haholo.
