ETPU Izinto Ezikhihliza Ugwebu Zinokushiyeka Kwabanye

Posted by: PECOAT | ngoSepthemba 7, 2023

Traditional EVA izinto zegwebu aziqiniseki kahle, futhi ngemuva kokugqoka isikhathi esithile, izinto zizowa futhi ziboleke. Ukushintsha impahla nge-POE, irabha, nezinye izinto kungalungisa futhi kuthuthukise izakhiwo zezinto ezibonakalayo, kodwa ukuthuthukiswa kunomkhawulo. Ngesikhathi esifanayo, kunezinkinga ezifana nokuncipha okuphezulu kanye nobunzima ekubumbeni. Inqubo yokukhiqiza isebenzisa amagwebu amakhemikhali, okungagcini nje ngokubangela ukungcola endaweni ezungezile kodwa futhi akhiqize izinsalela eziyingozi emzimbeni womuntu.

ETPU izinhlayiya zezinto ezinogwebu zinokuminyana kokukhanya kakhulu, zikwazi ukumelana nokuqina okuphezulu kakhulu, futhi zisebenzisa isikhutha esibucayi kakhulu njenge-ejenti egwebuzelayo ekulungiseni. Zenziwe ngendlela emsulwa yokukhihliza amagwebu emzimbeni, eluhlaza, evumelana nemvelo, engangcolisi, futhi engenazo izinsalela zamakhemikhali. Nokho, okwamanje ETPU izinto ezikhihliza amagwebu zisenawo amaphutha alandelayo.

1.Okwamanje, ubuchwepheshe bokulungiselela izinhlayiyana ezinegwebu abuvuthwa ngokwanele, kanye nokulungiselela ETPU izinhlayiya zincike kakhulu kokuhlangenwe nakho. I TPU inqubo yokukhihliza amagwebu nendlela yayo ayiqondi kahle, futhi zimbalwa izinkampani ezingawakhiqiza ngobuningi, okukude kakhulu nokuhlangabezana nesidingo semakethe. ETPU izinto ezikhihliza amagwebu.

2.Uma TPU izinhlayiya ezinamagwebu azikho ngaphansi kokwelashwa kwangemva kokwakheka, izinhlayiya ezinamagwebu zizoncipha kancane kancane zize zihlangane. Njengamanje, kuhlongozwa izindlela ezimbili zokwakha: indlela yokwenza ukupholisa okusheshayo kanye nendlela yesinxephezelo somoya wokubamba ukucindezela.

3.Ukushesha kwemishini icindezela, kugcwala futhi kukhanye ETPU izinhlayiya ze-foamingmaterials zizoba, futhi ukuphakama kwe-rebound kuya phezulu. Ngenxa yokungakwazi kwemishini ekhona ukuhlangabezana nezinga eliphezulu lokucindezeleka elidingekayo TPU ukukhihliza amagwebu, ukuthuthukiswa okwengeziwe kwemishini yokukhipha amagwebu kuyadingeka.

I-4. Ku TPU Inqubo yokufudumeza igwebu, izinduku zokushisa ze-thermocouple zivame ukusetshenziselwa ukushisa, okuholela ekushiseni okungalingani kwezinhlayiya, okuholela ebukhulu obungaguquki. ETPU izinhlayiya. Izinhlayiya ezinegwebu ezilungisiwe zinokuminyana okuphezulu, indawo emagebhugebhu, ukushwabana okukhulu, nokungamelani kahle nokuphuzi kanye ne-hydrolysis yezinhlayiya.

5.Ngesikhathi senqubo yokwenza i-midsole in ETPU izicathulo, indlela yokubumba yokushisela yesitimu esezingeni eliphezulu ingase ibangele ukushisela okungaphelele namaphethini angaphezulu angacacile, ikakhulukazi asekelwe ku-polyester. TPU, engase ingene ku-hydrolysis futhi ibe phuzi ngaphansi komhwamuko wamanzi onezinga lokushisa eliphezulu.

6.Okwamanje, iningi elilungisiwe ETPU izinhlayiya zezinto ezinogwebu ziyizinto ezinombala owodwa. Kunezindlela ezimbili zokufinyelela ezinombala ETPU: ukudaya okuqondile kwe TPU igwebu ngezingulube noma ukwethula ama-polyols adayiwe ukuze kulungiswe anombala TPU ngaphambi kokuphuma amagwebu.

Ukudaya okuqondile kwe TPU igwebu elinemibala yethula inkinga enkulu neyinselele, okuwukufuduka kwe-pigment okuholela ekuhlukeni kwemibala kumkhiqizo wokugcina. Lokhu kugqame kakhulu ekubumbeni umhwamuko wamanzi osezingeni eliphezulu, lapho inqubo yokushisisa iqhubekisela phambili ukukhuthaza ukufuduka kwamadayi ama-molecule amancane futhi kwandisa ukuhluka kombala.

Kwethulwa ama-polyols adayiwe ukuze kulungiswe anombala TPU ngaphambi kokuba igwebu livumela odayi ukuthi bahlakazeke ngendlela engabonakali ngaphakathi kwamaketanga e-polymer. Ngosizo lwama-agent ahlanganisayo afana ne-silane, ama-molecule kadayi axhunyelelwa emaketangeni e-polymer, avimbele ukufuduka kwama-molecule odayi ngaphakathi TPU ngaphansi komhwamuko wamanzi onezinga lokushisa eliphezulu. Nokho, le nqubo ihilela i-polymerization yezinto ezibonakalayo futhi inobunzima benqubo ephakeme.
