Itandukaniro riri hagati ya tpr na BR rubber mu nganda zikora caster rikubiyemo byose, ku bantu batarigeze bamenyana n'urusobe rw'amakuru biragoye cyane gutandukanya, uyu munsi n'inyigisho ihujwe n'ikibazo, ku nshuti zabo gusesengura itandukaniro riri hagati ya tpr na BR rubber mu buryo bwimbitse.
tpr ni impfunyapfunyo y'ibikoresho bya Thermo-Plastic-Rubber, dushobora kubyita ibikoresho bya thermoplastic rubber. Ni ibikoresho bya thermoplastic byoroshye bifite ubwisanzure budafite vulcanization, kandi bishobora gutunganywa no gutegurwa mu buryo butaziguye (nk'imashini zitera, extrusion, blow molding, nibindi).
1, ikoreshwa ry'ubushyuhe buri hagati ya -45-90 ℃, ubusanzwe ibikoresho bya tpr bishingiye ku gice cya SBS, imiterere yabyo ya shimi ni iyi ikurikira: kurwanya marble, kurwanya gusaza muri rusange, kurwanya ubushyuhe 70-75 ℃. Niba ukeneye ibikoresho byiza birwanya gusaza, ushobora guhitamo ibikoresho byahinduwe by'ibanze bya SEBS.
2, ubushobozi bwo kwihanganira imipira ya BR no kudashwanyagurika neza, kudacika intege no gushotora ni byiza cyane, ibikoresho bya tpr byoroshye kandi byoroshye kurusha imipira, ariko imbaraga zo gukurura, kudacika intege n'imiterere ya mekanike ntabwo ari byiza nka vulcanized rubber.
3, imiterere y’ibidukikije, ibikoresho bya tpr nk'umupira woroshye udahumanya ibidukikije, ibintu by'ingenzi biteza akaga nka pulasitiki zikoresha phthalate, nonylphenol NP, PAHs Kumenya PAHs, hakurikijwe amabwiriza ya ROHS, REACH, EN71-3, ASTMF963 yo gupima kurengera ibidukikije.
4, imiterere y'ubukana, ibikoresho bya tpr bishobora guhindurwa mu bukana bwa Shore dogere 5-100 z'ubukana bwabyo, ibikoresho byahinduwe bishingiye kuri SEBS bishobora guhindurwa ku bukana bwo hasi.
Rubber ya BR ni ibikoresho bya polymeri biremereye cyane bifite impinduka zishobora guhinduka, birareshya ku bushyuhe bw'icyumba, bishobora gutuma habaho impinduka nini bitewe n'imbaraga nto zo hanze, kandi bishobora kugarura imiterere y'umwimerere nyuma yo gukuraho imbaraga zo hanze. Rubber ni iya polymeri idahinduka burundu, ubushyuhe bwayo bwo guhindura ikirahure (T g) ni buke, uburemere bwa molekile akenshi buba bunini cyane, burenga ibihumbi amagana.
Reba itandukaniro riri hagati y'ibice bya TPR n'ibice bya rubber:
Hari ibikoresho byinshi byo gukora ku mpande z'ibiziga by'ibiziga, nka TPU casters, PP casters, TPR casters, PU casters, TPE casters, nylon casters, rubber casters n'ibindi.
1, ibyuma bicukura umupira bya BR byoroshye kandi bituje kurusha ibyuma bicukura umupira bya TPR.
2, ugereranije n'igiciro, rabha ntishobora kongera gukoreshwa, TPR ishobora kongera gukoreshwa, TPR igura make ugereranyije n'ibiciro bya BR.
4, mu rwego rwo kurengera ibidukikije, TPR ni ibikoresho bishya bitangiza ibidukikije, BR rubber ntabwo irinda ibidukikije.
