Uru na ọghọm nke ETPU Materials
ETPU (polyurethane na-ekpo ọkụ elastomer) bụ elastomer thermoplastic nke polyether polyols na polyisocyanates mejupụtara. Ebe a bụ uru na ọghọm nke ETPU ihe onwunwe:
uru:
1. Mgbochi iyi siri ike: ETPU nwere ike na ike dị elu karịa rọba ọdịnala na rọba, yabụ na ọ nwere nguzogide iyi siri ike na ịdịte aka.
2. Mgbochi mmanụ na mmiri: ETPU nwere ezigbo mmanụ na mmiri na-eguzogide mmiri, a pụkwara iji ya mee ihe ruo ogologo oge na ebe iru mmiri ma ọ bụ mmanu na-eme ka ọ ghara imebi ngwa ngwa.
3. Ezi nhazi usoro: ETPU Enwere ike ịhazi ihe dị iche iche nke ngwaahịa site na ịkpụzi injection, extrusion, calendering na ụzọ nhazi ndị ọzọ, nke nwere ike izute mkpa nke ngwa dị iche iche.
4. Ezi ngbanwe: ETPU nwere ezigbo elasticity na resilience, nke nwere ike belata mmetụta na ịma jijiji nke ọma, ma chebe ihe site na mmebi.
5. Enyi na gburugburu ebe obibi: ETPU ihe a na-emegharịgharị na gburugburu ebe obibi.
ọghọm:
1. Ọnụ ahịa dị elu: E jiri ya tụnyere roba omenala na ihe plastik, ETPU ka ọnụ.
2. Ogbenye elu okpomọkụ na-eguzogide: ETPU nwere adịghị mma elu okpomọkụ na-eguzogide na-apụghị iguzogide iji ogologo oge na elu okpomọkụ.
3. Ọ naghị eguzogide ụzarị ultraviolet: Mgbe ekpughere ya na ìhè anyanwụ ruo oge ụfọdụ. ETPU ga-esi ike, na-agbaji agbaji, na ọbụna tụfuo ngbanwe ya.
Na nchịkọta, ETPU ihe onwunwe nwere ọtụtụ uru, karịsịa na ngwa na-achọ ike dị elu, na-eyi nguzogide, na elasticity. Otú ọ dị, e nwekwara ụfọdụ ọghọm ndị a ga-amata, dị ka ọnụ ahịa dị elu, nguzogide okpomọkụ na-adịghị mma, na iguzogide ụzarị ultraviolet na-adịghị mma.
