Itandukaniro riri hagati ya reberi ya tpr na BR munganda za caster zirimo byose, kubantu batigeze bahura numuyoboro mubyukuri biragoye kubitandukanya, uyumunsi nibitekerezo byahujwe nurubanza, kugirango inshuti ziveho itandukaniro hagati reberi ya tpr na BR mubwimbitse.
tpr ni impfunyapfunyo ya Thermo-Plastike-Rubber, dushobora kuyita nkibikoresho bya thermoplastique. Nibikoresho bya thermoplastique byoroshye reberi hamwe na elastique idafite volcanisation, kandi irashobora gutunganywa no kubumba (nko gutera inshinge, gusohora, guhumeka, nibindi).
1, ikoreshwa ryubushyuhe -45-90 ℃, mubisanzwe bivugwa ko tpr ibikoresho bishingiye kubutaka bwa SBS, imiterere yimiti niyi ikurikira: kurwanya marble, kurwanya gusaza muri rusange, kurwanya ubushyuhe 70-75 ℃. Niba ukeneye gusaza ibikoresho byo kurwanya ubushyuhe bwo kurwanya ubushyuhe, urashobora guhitamo ibikoresho fatizo bya SEBS.
2, BR reberi yo kwihanganira no kurwanya abrasion nziza, kurwanya anti-kunyerera no gukurura ibintu ni byiza cyane, ibikoresho bya tpr byoroshye kandi byoroshye kuba byiza kuruta reberi, ariko imbaraga zingirakamaro zumubiri, kurwanya umunaniro hamwe nubukanishi ntabwo ari byiza nka reberi yibirunga.
3, ibiranga ibidukikije, ibikoresho bya tpr nkibikoresho byangiza ibidukikije byangiza ibidukikije, ibintu byingenzi bishobora guteza akaga nka plasitike phthalate Phthalate, nonylphenol NP, PAHs PAHs gutahura, bijyanye na ROHS, REACH, EN71-3, ASTMF963 ibipimo byo gupima ibidukikije.
4, ibiranga ubukana, ibikoresho bya tpr birashobora guhindurwa mubukomere bwa Shore dogere 5-100 yubukomere bwabyo, ibikoresho byahinduwe bishingiye kuri SEBS birashobora guhindurwa mubukomere buke.
BR reberi ni ibikoresho bya polymer byoroshye cyane kandi bigahinduka, bigahinduka mubushyuhe bwicyumba, birashobora kubyara ihinduka rinini bitewe nimbaraga ntoya yo hanze, kandi irashobora kugarura imiterere yambere nyuma yo gukuraho imbaraga ziva hanze. Rubber ni ya polymer yuzuye ya amorphous, ubushyuhe bwayo bwikirahure (T g) buri hasi, uburemere bwa molekile akenshi ni bunini cyane, burenga ibihumbi magana.
Reba itandukaniro riri hagati ya TPR na rubber:
Hano haribikoresho byinshi byubuso bwibiziga, nkibya TPU, ibyuma bya PP, ibyuma bya TPR, PU, ibyuma bya TPE, ibyuma bya nylon, ibyuma bya reberi nibindi.
1, BR reberi ya BR yoroshye kandi ituje kuruta TPR.
2, ugereranije nigiciro, reberi ntishobora gukoreshwa, TPR irashobora gutunganywa, imashini ya TPR igura amafaranga make ugereranije na BR rubber.
4, duhereye ku kurengera ibidukikije, TPR ni ibikoresho bishya bitangiza ibidukikije, reberi ya BR ntabwo yangiza ibidukikije.
