Gwiritsani ntchito njira 7 izi kuti muzindikire TPE ndi TPU!

TPE ikulankhula momveka bwino mawu onse a thermoplastic elastomers.Amagawidwa motere:

Koma zomwe nthawi zambiri zimatchedwa TPE ndizophatikiza za SEBS / SBS + PP + naphthenic mafuta + calcium carbonate + othandizira.Imatchedwanso pulasitiki yofewa yothandiza zachilengedwe m'makampani, koma nthawi zina imatchedwa TPR (imakonda kutchedwa ku Zhejiang ndi Taiwan) ).TPU, wotchedwanso polyurethane, ali mitundu iwiri: polyester mtundu ndi polyether mtundu.

TPE ndi TPU onse ndi zida za thermoplastic zokhala ndi mphira wa rabara.Zipangizo za TPE ndi TPU zokhala ndi kuuma kofanana nthawi zina zimakhala zovuta kusiyanitsa TPE ndi TPU pongoyang'ana ndi maso.Koma kuyambira mwatsatanetsatane, titha kusanthulabe kusiyana ndi kusiyana pakati pa TPE ndi TPU kuchokera kuzinthu zambiri.

1.Kuwonetsetsa

Kuwonekera kwa TPU ndikwabwino kuposa kwa TPE, ndipo sikophweka kumamatira ngati TPE yowonekera.

2. Gawo

Gawo la TPE limasiyanasiyana mosiyanasiyana, kuyambira 0,89 mpaka 1.3, pomwe TPU imachokera ku 1.0 mpaka 1.4.M'malo mwake, pakugwiritsa ntchito, iwo amawonekera makamaka mu mawonekedwe osakanikirana, kotero mphamvu yokoka yeniyeni imasintha kwambiri!

3.Kukana kwamafuta

TPU ili ndi kukana bwino kwamafuta, koma ndizovuta kuti TPE ikhale yosamva mafuta.

4.Atawotcha

TPE imakhala ndi fungo lonunkhira bwino ikayaka, ndipo utsi woyaka ndi wocheperako komanso wopepuka.Kuyaka kwa TPU kumakhala ndi fungo linalake, ndipo pamamveka kuphulika pang'ono poyaka.

5.Mechanical katundu

TPU ya elasticity ndi zotanuka kuchira katundu (flexion resistance ndi creep resistance) ndiabwino kuposa TPE.

Chifukwa chachikulu ndikuti mawonekedwe a TPU ndi mawonekedwe a polima osakanikirana ndipo ali m'gulu la utomoni wa polima.TPE ndi zinthu za alloy zomwe zimakhala ndi magawo ambiri ophatikizidwa ndi kuphatikiza kwamitundu yambiri.

Kuwongolera kolimba kwambiri kwa TPE kumakonda kusinthika kwazinthu, pomwe TPU imawonetsa kukhazikika bwino pamagawo onse owuma, ndipo mankhwalawo si osavuta kupunduka.

6.Kutentha kwa kutentha

TPE ndi -60 digiri Celsius ~ 105 digiri Celsius, TPU ndi -60 digiri Celsius ~ 80 digiri Celsius.

7.Kuwoneka ndi kumva

Pazinthu zina zochulukirachulukira, zopangidwa ndi TPU zimakhala ndi malingaliro owopsa komanso kukana kukangana kwamphamvu;pomwe zinthu zopangidwa ndi TPE zimakhala ndi zofewa komanso zofewa komanso zomakangana zofooka.

Mwachidule, TPE ndi TPU ndi zida zofewa komanso zimakhala ndi mphira wabwino.Poyerekeza, TPE ndiyabwino kwambiri potengera chitonthozo champhamvu, pomwe TPU imawonetsa kukhazikika komanso mphamvu.
