Phapang pakeng tsa tpr le BR rabara indastering ea caster e akaretsa, bakeng sa ba e-s'o kopane le marang-rang ho hlile ho le thata ho khetholla, kajeno ho tloha khopolong e kopantsoeng le nyeoe, bakeng sa metsoalle ho senya phapang pakeng tsa tpr le BR rabara ka botebo.
tpr ke khutsufatso ea thepa ea Thermo-Plastic-Rubber, re ka e bitsa e le thepa ea rabara ea thermoplastic. Ke thepa ea rabara e bonolo ea thermoplastic e nang le elasticity ntle le vulcanization, 'me e ka sebetsanoa ka ho toba le ho bōptjoa (e kang ho bōptjoa ha ente, extrusion, blowing, joalo-joalo).
1, tšebeliso ea mocheso oa mocheso -45-90 ℃, hangata o re tpr thepa e thehiloe ho SBS substrate, thepa ea eona ea lik'hemik'hale e tjena: ho hanyetsa marble, ho hanyetsa botsofali ka kakaretso, ho hanyetsa mocheso 70-75 ℃. Haeba o hloka lisebelisoa tse ntle tsa ho hanyetsa mocheso oa botsofali, o ka khetha lisebelisoa tse fetotsoeng tsa SEBS.
2, ho tiea ha rabara ea BR le khanyetso e ntle ea abrasion, anti-slip le ts'ebetso ea ho ts'oaroa ha ts'oenyeho e ntle haholo, thepa ea tpr e bonolo ebile e phutholohile ho feta rabara, empa matla a matla a thepa, ho hanyetsa mokhathala le thepa ea mochini ha e ntle joalo ka rabara e hlabositsoeng.
3, litšoaneleho tsa tikoloho, thepa ea tpr e le rabara e bonolo ea tikoloho, lintho tse ka sehloohong tse kotsi tse kang plasticizers phthalates Phthalate, nonylphenol NP, PAHs PAHs ho lemoha, tumellanong le ROHS, REACH, EN71-3, ASTMF963 litekanyetso tsa tlhahlobo ea tšireletso ea tikoloho.
4, litšoaneleho tse thata, thepa ea tpr e ka fetoloa ka thata ea Shore 5-100 likhato tsa boima ba eona, lisebelisoa tse fetotsoeng tse thehiloeng ho SEBS li ka fetoloa ho boima bo tlase.
BR rabara ke ntho e entsoeng ka polymer e otlolohileng haholo e nang le deformation e fetolehang, e reketla mocheso oa kamore, e ka hlahisa deformation e kholo tlasa ts'ebetso ea matla a manyane a kantle, mme e ka khutlisetsa boemo ba pele kamora ho tlosa matla a kantle. Rubber ke ea polymer ea amorphous ka ho feletseng, mocheso oa eona oa phetoho ea khalase (T g) o tlaase, boima ba molek'hule hangata bo boholo haholo, ho feta makholo a likete.
Sheba phapang lipakeng tsa li-casters tsa TPR le li-casters tsa rabara:
Ho na le lisebelisoa tse ngata bakeng sa holim'a lebili la li-casters, tse kang li-caster tsa TPU, li-caster tsa PP, li-caster tsa TPR, li-caster tsa PU, li-caster tsa TPE, li-caster tsa nylon, li-caster tsa rabara joalo-joalo.
1, li-caster tsa rabara tsa BR li bonolo ebile li khutsitse ho feta li-caster tsa TPR.
2, ha e bapisoa le litšenyehelo, rabara e ke ke ea sebelisoa hape, TPR e ka sebelisoa hape, li-caster tsa TPR li bitsa chelete e ka tlase ho li-casters tsa rabara tsa BR.
4, ho ea ka pono ea ts'ireletso ea tikoloho, TPR ke thepa e ncha e nang le botsoalle ba tikoloho, rabara ea BR ha e na tikoloho.
