Bambancin Tsakanin TPU Da Rubber

TPU (Thermoplastic polyurethanes) abu ne tsakanin roba da filastik.Kayan abu yana da mai da ruwa kuma yana da kyakkyawar ɗaukar nauyi da juriya mai tasiri.TPU abu ne na polymer wanda ba mai guba ba.Tpu abu yana da abũbuwan amfãni daga high elasticity na roba da kuma aiki yi na filastik.Ba ya buƙatar vulcanization kuma ana iya sarrafa shi ta hanyar injunan gyare-gyaren thermoplastic na yau da kullun.A taƙaice, thermoplastic elastomer tpu an haɗa shi da ma'aunin zafi da sanyio kuma ana iya samar da shi ta amfani da injunan gyare-gyaren allura, extruders, injunan gyare-gyare.Scrap da ragowar ana iya sake yin amfani da su 100%, kayan da aka zaɓa don maye gurbin PVC, roba da silicone kuma sun mamaye masana'antar roba da robobi.

Rubber: Rubber polymer ce ta kwayoyin halitta tare da nauyin kwayoyin halitta na daruruwan dubban.Ana buƙatar jiyya na vulcanization don kula da babban elasticity a cikin kewayon zafin jiki na -50 zuwa 150 ° C.Low na roba modulus, 3 oda na girma kasa da na talakawa kayan, babban nakasawa, elongation iya isa 1000% (General kayan ne kasa da 1%), zafi da aka saki a lokacin mikewa tsari, da kuma elasticity yana ƙaruwa da zafin jiki, wanda shi ne m. fiye da na kayan gabaɗaya akasin haka.

Bambanci tsakanin TPU da roba:

1. Rubber yana da laushi mai laushi, kuma iyakar taurin (0-100a) na kayan tpu yana da fadi sosai tsakanin roba da filastik;

2. Ma'anar elastomer yana da faɗi sosai, kuma ana kiran tpu thermoplastic rubber (tpr), kuma rubber yawanci yana nufin rubber thermosetting;

3. Hanyoyin sarrafawa sun bambanta.Ana sarrafa roba ta hanyar hada roba, yayin da TPU yawanci ana sarrafa shi ta hanyar extrusion;

4. Kaddarorin sun bambanta.Rubber yawanci yana buƙatar ƙara abubuwa daban-daban kuma yana buƙatar vulcanized don ƙarfafawa, yayin da aikin tpu na elastomers na thermoplastic yana da kyau sosai;

5. Thermoplastic elastomer tpu yana da tsarin layi na layi kuma an haɗa shi ta jiki ta hanyar haɗin gwiwar hydrogen.Haɗin hydrogen yana karye a yanayin zafi mai girma kuma filastik ne.Rubber yana haɗe-haɗe ta hanyar sinadarai kuma ba thermoplastic ba.

6. TPU filastik abu yana da kyakkyawan juriya na lalacewa, wanda ya fi sau biyar fiye da na roba na halitta, kuma yana daya daga cikin kayan da aka fi so don samfurori masu jurewa.
