Itandukaniro hagati ya TPU na Rubber

TPU (Thermoplastique polyurethanes) ni ibikoresho hagati ya reberi na plastiki.Ibikoresho birwanya amavuta namazi kandi bifite imitwaro myiza kandi itwara ingaruka.TPU ni ibidukikije byangiza ibidukikije bidafite ubumara bwa polymer.Ibikoresho bya Tpu bifite ibyiza byo gukomera kwa reberi no gutunganya plastike.Ntabwo isaba ibirunga kandi irashobora gutunganywa nimashini zisanzwe za termoplastique.Muri make, thermoplastique elastomer tpu ni thermoformed kandi irashobora kubyazwa umusaruro ukoresheje imashini zitera inshinge, extruders, imashini zibumba.Ibisigazwa n'ibisigara birashobora gukoreshwa 100%, ibikoresho fatizo byo guhitamo gusimbuza PVC, reberi na silicone kandi biganje mu nganda za rubber na plastiki.

Rubber: Rubber ni polymer organic ifite uburemere bwa molekile ibihumbi magana.Kuvura Vulcanisation birasabwa kugira ngo habeho ubukana bwinshi mu bushyuhe buri hagati ya 50 na 150 ° C.Modulus yo hasi ya elastike, ordre 3 yubunini munsi yibikoresho bisanzwe, deformasiyo nini, kuramba birashobora kugera kuri 1000% (ibikoresho rusange ntibiri munsi ya 1%), ubushyuhe burekurwa mugihe cyo kurambura, kandi elastique yiyongera hamwe nubushyuhe, nabwo bukaba buri hasi kuruta ibikoresho rusange muri rusange.

Itandukaniro riri hagati ya TPU na rubber:

1. Rubber iroroshye cyane, kandi ubukana (0-100a) bwibikoresho bya tpu ni binini cyane hagati ya reberi na plastiki;

2. Igitekerezo cya elastomer ni kigari cyane, tpu nanone yitwa reberi ya termoplastique (tpr), naho reberi ikunze kuvuga reberi ya termosetting;

3. Uburyo bwo gutunganya buratandukanye.Rubber itunganywa no kuvanga reberi, mugihe TPU isanzwe itunganywa no gukuramo;

4. Imiterere iratandukanye.Ubusanzwe reberi ikenera kongeramo inyongeramusaruro zitandukanye kandi igomba guhindurwa mubirunga kugirango ishimangire, mugihe tpu imikorere ya thermoplastique elastomers nibyiza cyane;

5. Thermoplastique elastomer tpu ifite imiterere yumurongo kandi ihujwe kumubiri no guhuza hydrogen.Amazi ya hydrogène avunika ku bushyuhe bwinshi kandi ni plastiki.Rubber ihujwe na chimique ntabwo ari thermoplastique.

6. Ibikoresho bya pulasitiki ya TPU bifite imbaraga zo kurwanya kwambara, bikubye inshuro zirenga eshanu za reberi karemano, kandi nikimwe mubikoresho byatoranijwe kubicuruzwa bidashobora kwambara.
