Umehluko phakathi kwenjoloba ye-tpr ne-BR embonini ye-caster ihlanganisa konke, kulabo abangazange baxhumane nenethiwekhi kunzima ngempela ukuhlukanisa, namuhla kusukela kumbono ohlangene necala, ukuze abangane baphule umehluko phakathi i-tpr ne-BR irabha ekujuleni.
I-tpr isifinyezo se-Thermo-Plastic-Rubber material, singabhekisela kuyo njengento yerabha ye-thermoplastic. Kuyinto yerabha ethambile ye-thermoplastic ene-elasticity ngaphandle kwe-vulcanization, futhi ingacutshungulwa ngokuqondile futhi ibunjwe (njengokubumba umjovo, ukukhishwa, ukubunjwa kokushaywa, njll.).
I-1, ukusetshenziswa kwezinga lokushisa -45-90 ℃, ngokuvamile kuthiwa impahla ye-tpr isekelwe ku-substrate ye-SBS, izakhiwo zayo zamakhemikhali zimi kanje: ukumelana nemabula, ukumelana nokuguga ngokuvamile, ukumelana nezinga lokushisa 70-75 ℃. Uma udinga izinto ezinhle zokumelana nezinga lokushisa lokumelana nokuguga, ungakhetha izinto eziguquliwe zesisekelo se-SEBS.
I-2, ukuqina kwerabha ye-BR kanye nokumelana okuhle nokuhuzuka, ukusebenza kwe-anti-slip kanye nokumuncwa kokushaqeka kuhle kakhulu, impahla ye-tpr ithambile futhi inethezekile ukuze ibe ngaphezu kwerabha, kodwa amandla aqinile wezinto ezibonakalayo, ukumelana nokukhathala kanye nezakhiwo zemishini azilungile njengerabha eshisiwe.
3, izici zemvelo, izinto ze-tpr njengenjoloba ethambile evumelana nemvelo, izinto eziyingozi eziyinhloko njengama-plasticizers phthalates Phthalate, nonylphenol NP, ukutholwa kwe-PAHs PAHs, ngokuhambisana ne-ROHS, REACH, EN71-3, ASTMF963 amazinga okuhlola ukuvikelwa kwemvelo.
4, izici zobulukhuni, impahla ye-tpr ingalungiswa ku-Shore hardness 5-100 degrees of its hardness, izinto eziguquliwe ezisekelwe ku-SEBS zingalungiswa zibe lukhuni obuphansi.
Irabha ye-BR iyinto enwebeka kakhulu ye-polymer ene-deformation ebuyela emuva, enwebekayo ekamelweni lokushisa, ingaveza ukuwohloka okukhulu ngaphansi kwesenzo samandla amancane angaphandle, futhi ingabuyisela isimo sangempela ngemva kokukhipha amandla angaphandle. Irabha ingeyepolymer e-amorphous ngokuphelele, izinga lokushisa layo lengilazi (T g) liphansi, isisindo samangqamuzana ngokuvamile sikhulu kakhulu, ngaphezu kwamakhulu ezinkulungwane.
Bheka umehluko phakathi kwe-TPR casters nama-rubber casters:
Ziningi izinto ezisetshenziswa ebusweni besondo lama-casters, njengama-TPU casters, ama-PP casters, ama-TPR casters, ama-PU casters, ama-TPE casters, ama-nylon casters, ama-rubber casters nokunye.
1, izikhangisi zenjoloba ze-BR zithambile futhi zithule kunabakhangisi be-TPR.
2, uma kuqhathaniswa nezindleko, irabha ayikwazi ukugaywa kabusha, i-TPR ingagaywa kabusha, ama-casters e-TPR abiza ngaphansi kwama-rubber casters we-BR.
4, ngokombono wokuvikelwa kwemvelo, i-TPR iyinto entsha ehambisana nemvelo, irabha ye-BR ayihambisani nemvelo.
