TPU (Polurethane yo mu bwoko bwa Thermoplastic)ikoreshwa mu kubaka uburyo butandukanye bwo kwirinda amazi, harimo uturemangingo duhumeka tudahumeka, impapuro zirinda amazi, udupira dushyushye twometseho, n'udupira two gupfuka, kugira ngo ihuze n'ibikenewe mu buryo butandukanye bwo kwirinda amazi, kwirinda amazi no gufunga.
√ Impapuro z'ingenzi zo gusaba akazi n'ingero
- Impapuro zo kwirinda amazi / Uturemangingo: Bikoreshwa nk'ibice bito bito bidashobora amazi mu mishinga minini nko ku bisenge, mu mazu yo munsi y'ubutaka, mu miyoboro y'amazi, mu biraro, no mu bigega by'amazi.
- Uduce duhumeka tudapfa guhumeka: Reka umwuka w'amazi usohoke mu gihe ubuza amazi kwinjira mu mazi yo hanze - bikwiranye n'uruhande rw'inyuma rw'ibikoresho bikingira inyubako kugira ngo byongere umwuka utagira amazi, bikoreshwa ku nkuta, ku bisenge, no ku nyubako z'ibiti.
- Ibikoresho byo Gufunga Bidakoresha Amazi: Bikoreshwa mu guhuza uruzitiro, impande z'uruzitiro, imizi y'imiyoboro n'ibindi bisobanuro, cyangwa nk'ibikoresho byo gufunga bivamo amazi mu kwagura no kubaka ihuriro.
- Irangi ritaziba: Rishyirwa ku gipfundikizo ku sima, icyuma, n'ibindi bikoresho kugira ngo rikore firime idaziba idafite umugozi - ikwiriye pisine, hasi mu nganda, n'ibindi.
- Ikirahure cy’umutekano cya Laminated: Filimi ikomeye ya TPU ifata neza ibice by’ikirahure kugira ngo idacika - ikoreshwa mu nkuta z’amarido n’amatara yo hejuru.
√ Ibipimo bisanzwe bya tekiniki n'imikorere
- Imiterere ifatika/iy'imashini:
Ubusanzwe imbaraga zo gukurura impapuro zidashobora kuvogerwa n'amazi ni 30–45 MPa, uburebure bw'aho zihagarara ni 500–700%, ubunini bwa mm 0.2–0.5.
Imyenda ya TPU ivanze ifite ubushobozi bwo gutobora ≥80 N/mm² kandi ikagira uburebure mu gihe cyo kuruhuka ≥300%. - Kuramba no Guhagarara:
Ahantu ho gushonga ni hafi 90°C, ubushyuhe bwo guhindagurika kw'ubushyuhe ni 70–90°C.
Nyuma y'amasaha 500 ubushyuhe bumaze gusaza kuri 80°C, imbaraga zo gukurura zigabanuka <5%.
Imikorere ihamye kuri -40°C; imiterere imwe ishobora gukoreshwa kugeza kuri -65°C. - Ibidukikije n'umutekano:
TPU ntabwo ari uburozi, nta mpumuro, kandi ntigira ingaruka ku bidukikije.
Ifu ikomeye 100% ntabwo itanga imyuka ya VOC, ihuye n'ibisabwa mu bwubatsi bw'icyatsi kibisi.
√ Ingingo zo kubaka no gukoresha
- Uburyo bwo kuvanga: Urugero, kuvanga 69.2% TPU, 30% ifu ya rubber, na 0.8% defoamer bishobora gukora ibikoresho bihendutse kandi bidakoresha amazi byo gufunga ibyuma bivangwa n'amazi mu muhanda wa gari ya moshi wihuta.
- Guhitamo inzira:
- Ifu ya TPU: gusiga irangi + gukanda bishyushye
- Filimi ishyushye ya TPU: gusudira hakoreshejwe frequency nyinshi cyangwa ultrasonic
- Urupapuro rwa TPU: gusudira umwuka ushyushye cyangwa kole idasanzwe yo guhuza
- Gukomera ku bushyuhe ni ingenzi cyane: Kurwanya amazi ni ingenzi mu kubaka inyubako zirinda amazi. Ingano zimwe na zimwe za TPU zirangirika cyane mu mazi ashyushye igihe kirekire; ubushuhe bwinshi bushobora gutera hydrolysis bigatuma ifunga rinanirwa. Kubwibyo, guhitamo urwego rudahangarwa na hydrolysis ni ingenzi cyane.
- Gutunganya ubuso ni ingenzi: Ku bintu bifite imyenge cyangwa byoroshye, gukoresha primer ijyanye nabyo birushaho gufatana neza hagati y’igitambaro cya TPU n’igitambaro, bigatuma urwego rudapfa amazi rugumana ubuziranenge muri rusange.
- Ku bijyanye no kubaka ibikoresho byo kwirinda amazi,TPU ishingiye kuri polyetherbyakozwe naYantai Linghua ibikoresho bishyaUbusanzwe ni yo mahitamo meza kuko imigozi yayo ya ether (-COC-) itanga ubudahangarwa bukomeye bwa hydrolysis kandi ikaba ikwiriye ahantu hatose igihe kirekire.
