Phapang pakeng tsa rabara ea tpr le BR indastering ea caster e akaretsa tsohle, ho bao ba sa kang ba kopana le marang-rang ho thata haholo ho khetholla, kajeno ho tsoa khopolo-taba e kopantsoeng le nyeoe, hore metsoalle e arole phapang pakeng tsa rabara ea tpr le BR ka botebo.

tpr ke khutsufatso ea thepa ea Thermo-Plastic-Rubber, re ka e bitsa thepa ea rabara ea thermoplastic. Ke thepa ea rabara e bonolo ea thermoplastic e nang le ho tenyetseha ntle le vulcanization, 'me e ka sebetsoa le ho bōptjoa ka ho toba (joalo ka ho enta ka ente, ho ntša metsi, ho phunya, jj.).

1, tšebeliso ea mocheso o fapaneng -45-90 ℃, hangata thepa ea tpr e thehiloe holim'a substrate ea SBS, litšobotsi tsa eona tsa lik'hemik'hale ke tse latelang: ho hanyetsa 'mabole, ho hanyetsa botsofali ka kakaretso, ho hanyetsa mocheso 70-75 ℃. Haeba u hloka thepa e ntle ea ho hanyetsa botsofali, u ka khetha thepa ea motheo ea SEBS e fetotsoeng.

2, ho mamella rabara ea BR le ho hanyetsa ho khohlela hantle, ts'ebetso ea ho thibela ho thella le ho monya ha shock e ntle haholo, thepa ea tpr e bonolo ebile e phutholohile ho feta rabara, empa matla a ho thaepa a thepa, ho hanyetsa mokhathala le thepa ea mechini ha li ntle joaloka rabara e qhibilihisitsoeng.

3, litšobotsi tsa tikoloho, thepa ea tpr e le rabara e bonolo e mosa tikolohong, lintho tse kotsi tse ka sehloohong tse kang li-plasticizers phthalates Phthalate, nonylphenol NP, PAHs PAHs detection, ho latela maemo a ROHS, REACH, EN71-3, ASTMF963 a tlhahlobo ea ts'ireletso ea tikoloho.

4, litšobotsi tsa thatafalo, thepa ea tpr e ka fetoloa ho thatafalo ea Shore likhato tse 5-100 tsa thatafalo ea eona, thepa e fetotsoeng e thehiloeng ho SEBS e ka fetoloa ho thatafalo e tlase.

Rabara ea BR ke thepa ea polymer e tenyetsehang haholo e nang le phetoho e ka fetoloang, e tenyetsehang mochesong oa kamore, e ka hlahisa phetoho e kholo tlas'a ts'ebetso ea matla a manyane a kantle, 'me e ka khutlisa boemo ba pele ka mor'a ho tlosa matla a kantle. Rabara ke ea polymer e sa fetoheng ka botlalo, mocheso oa eona oa phetoho ea khalase (T g) o tlase, boima ba limolek'hule hangata bo boholo haholo, bo feta makholo a likete.

Sheba phapang pakeng tsa li-caster tsa TPR le li-caster tsa rabara:

Ho na le thepa e mengata bakeng sa bokaholimo ba mabili a li-caster, joalo ka 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 le tse ling.

1, di-caster tsa rabara tsa BR di bonolo ebile di khutsitse ho feta di-caster tsa TPR.

2, ha ho 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-caster tsa rabara tsa BR.

4, ho ya ka pono ya tshireletso ya tikoloho, TPR ke thepa e ntjha e sireletsang tikoloho, rabara ya BR ha e sireletse tikoloho.
