Umehluko phakathi kwerabha ye-tpr ne-BR embonini ye-caster uhlanganisa konke, kulabo abangazange baxhumane nenethiwekhi kunzima kakhulu ukuhlukanisa, namuhla kusukela kumbono ohlanganiswe necala, ukuthi abangani bahlukanise umehluko phakathi kwerabha ye-tpr ne-BR ngokujulile.
I-tpr yisifinyezo sezinto ze-Thermo-Plastic-Rubber, singayibiza ngokuthi izinto zerabha ze-thermoplastic. Iyinto yerabha ethambile ye-thermoplastic enokuguquguquka ngaphandle kwe-vulcanization, futhi ingacutshungulwa futhi ibunjwe ngokuqondile (njengokubumba ngomjovo, ukukhipha, ukubumba ngokushaywa, njll.).
1, ukusetshenziswa kwezinga lokushisa -45-90 ℃, ngokuvamile izinto ze-tpr zisekelwe ku-SBS substrate, izakhiwo zayo zamakhemikhali zimi kanje: ukumelana nemabula, ukumelana nokuguga ngokuvamile, ukumelana nokushisa 70-75 ℃. Uma udinga izinto ezinhle zokumelana nokuguga, ungakhetha izinto ezishintshiwe zezinto eziyisisekelo ze-SEBS.
2, ukuqina kwerabha ye-BR kanye nokumelana okuhle nokuklwebheka, ukusebenza kokulwa nokushelela kanye nokumuncwa kokushaqeka kuhle kakhulu, izinto ze-tpr zithambile futhi zikhululekile ukuba zingcono kunerabha, kodwa amandla okuthamba kwezinto, ukumelana nokukhathala kanye nezakhiwo zemishini azilungile njengerabha evulcanized.
3, izici zemvelo, izinto ze-tpr njengerabha ethambile enobungani nemvelo, izinto eziyingozi eziyinhloko njenge-plasticizers phthalates Phthalate, nonylphenol NP, PAHs Ukutholwa kwama-PAH, ngokuhambisana nezindinganiso zokuhlola ukuvikelwa kwemvelo ze-ROHS, REACH, EN71-3, ASTMF963.
4, izici zobulukhuni, izinto ze-tpr zingalungiswa ku-Shore hardness degrees 5-100 zobunzima bazo, izinto eziguquliwe ezisekelwe ku-SEBS zingalungiswa zibe ubulukhuni obuphansi.
Irabha ye-BR iyinto ye-polymer enwebeka kakhulu enokuguquguquka okuguqukayo, enwebeka ekushiseni kwegumbi, ingakhiqiza ukuguqulwa okukhulu ngaphansi kwesenzo samandla amancane angaphandle, futhi ingabuyisela isimo sokuqala ngemva kokususa amandla angaphandle. Irabha ingeye-polymer engaguquki ngokuphelele, izinga lokushisa layo lokuguquka kwengilazi (T g) liphansi, isisindo sama-molecule sivame ukuba sikhulu kakhulu, singaphezu kwamakhulu ezinkulungwane.
Bheka umehluko phakathi kwama-TPR casters nama-raber casters:
Kunezinto eziningi zokwakha ubuso besondo lama-casters, njengezi-TPU casters, izi-PP casters, izi-TPR casters, izi-PU casters, izi-TPE casters, izi-nylon casters, izi-raber casters njalo njalo.
1, ama-caster enjoloba e-BR athambile futhi athule kune-caster ye-TPR.
2, uma kuqhathaniswa nezindleko, irabha ayikwazi ukuphinda isetshenziswe, i-TPR ingaphinde isetshenziswe, ama-TPR casters abiza kancane kune-BR casters yerabha.
4, ngokombono wokuvikelwa kwemvelo, i-TPR iyinto entsha enobungani nemvelo, irabha ye-BR ayinabungani nemvelo.
