Umahluko phakathi kwerabha ye-tpr kunye ne-BR kwishishini le-caster ubandakanya yonke into, kwabo bangakhange banxibelelane nenethiwekhi kunzima kakhulu ukwahlula, namhlanje kwithiyori edibene nemeko, kubahlobo ukwahlula umahluko phakathi kwerabha ye-tpr kunye ne-BR ngokubanzi.
I-tpr sisifinyezo sezinto ze-Thermo-Plastic-Rubber, singazibiza ngokuba zizinto zerabha ze-thermoplastic. Yinto yerabha ethambileyo ye-thermoplastic enobuthambileyo ngaphandle kwe-vulcanization, kwaye inokucutshungulwa ngqo kwaye ibunjwe (njengokubumba ngenaliti, ukukhupha, ukubumba nge-blow, njl.njl.).
1, ukusetyenziswa koluhlu lobushushu -45-90 ℃, ngokuqhelekileyo izinto ze-tpr zisekelwe kwi-SBS substrate, iipropati zayo zeekhemikhali zezi zilandelayo: ukumelana nemabula, ukumelana nokwaluphala ngokubanzi, ukumelana nobushushu 70-75 ℃. Ukuba ufuna izixhobo ezilungileyo zokulwa nokwaluphala, ungakhetha izixhobo ezilungisiweyo zezinto zesiseko se-SEBS.
2, Ukuqina kwerabha ye-BR kunye nokumelana okuhle nokukrala, ukusebenza kokungatyibiliki kunye nokufunxwa komothuko kugqwesileyo, izinto ze-tpr zithambile kwaye zikhululekile ukuba zibe ngcono kunerabha, kodwa amandla okuxinana kwezinto, ukumelana nokudinwa kunye neempawu zoomatshini azilunganga njengerabha evulcanized.
3, iimpawu zokusingqongileyo, izinto ze-tpr njengerabha ethambileyo enobuhlobo nokusingqongileyo, izinto eziphambili eziyingozi ezifana neeplastiki ezisebenzisa i-phthalates, i-Phthalate, i-nonylphenol NP, ii-PAHs Ukufunyanwa kwee-PAHs, ngokuhambelana nemigangatho yovavanyo lokukhuselwa kokusingqongileyo ye-ROHS, i-REACH, i-EN71-3, i-ASTMF963.
4, iimpawu zobulukhuni, izinto ze-tpr zinokulungiswa kwi-Shore hardness degrees 5-100 yobunzima bayo, izinto eziguqulweyo ezisekelwe kwi-SEBS zinokulungiswa kwi-hardness ephantsi.
Irabha ye-BR yinto yepolymer ethambileyo kakhulu ene-deformation eguqukayo, ethambileyo kubushushu begumbi, inokuvelisa i-deformation enkulu phantsi kwesenzo samandla amancinci angaphandle, kwaye inokubuyisela imeko yokuqala emva kokususa amandla angaphandle. Irabha yeyepolymer engaguqukiyo ngokupheleleyo, ubushushu bayo botshintsho lweglasi (T g) buphantsi, ubunzima bemolekyuli buhlala bukhulu kakhulu, bungaphezulu kwamakhulu amawaka.
Jonga umahluko phakathi kwee-TPR casters kunye nee-rubber casters:
Kukho izinto ezininzi zokwenza umphezulu wamavili ee-casters, ezinje ngee-TPU casters, ii-PP casters, ii-TPR casters, ii-PU casters, ii-TPE casters, ii-nylon casters, ii-raber casters njalo njalo.
1, ii-casters zerabha ze-BR zithambile kwaye azixoli kunee-casters ze-TPR.
2, xa kuthelekiswa neendleko, irabha ayinakuphinde isetyenziswe, i-TPR ingaphinda isetyenziswe, ii-TPR casters zibiza ngaphantsi kunee-BR raber casters.
4, ngokwembono yokhuseleko lokusingqongileyo, i-TPR yinto entsha enobuhlobo nokusingqongileyo, irabha ye-BR ayinabuhlobo nokusingqongileyo.
