Ifite imiterere myiza irimo kurwanya kwangirika cyane, ubushyuhe bwinshi, ubushobozi bwo kwirinda amazi, gukomera mu bushyuhe buke, gufunga ubushyuhe no kutangiza ibidukikije, TPU ikorwa naYantai Linghua New Material Co., Ltd.ikoreshwa cyane mu mitwaro yo hagati kugeza ku ihanitse mu bice bitatu by'ingenzi: imyenda yoroshye ifite amakaseti, igitambaro cyo hejuru ku masanduku akomeye n'ibikoresho bikora neza bikozwe mu inshinge.
1. Umuzigo w'ibitugu byoroshye:TPUImyenda ya Laminated (Igice kinini gikoreshwa)
1.1 Imiterere y'ibanze
Igitambaro cya polyester cyangwa nylon oxford gifite firime ya TPU ya 0.08 ~ 0.4 mm binyuze mu gukanda ubushyuhe, kigabanyijemo TPU ishingiye kuri polyester na TPU ishingiye kuri polyether:
- Polyester TPU: Irwanya cyane gushwanyagurika no gucikagurika kw'amavuta, imbaraga zikomeye zo gukurura no gucikagurika (≥8 N/cm), ni nziza cyane ku mizigo yo kwiyandikisha mu kazi;
- Polyether TPU: Irwanya cyane hydrolysis, iguma yoroshye kugeza kuri -30°C idakomera, ikunda gukoreshwa mu gutwara imizigo yo hanze no mu ntera ndende.
1.2 Ibyiza by'ingenzi ku mikorere
- Idapfa amazi: Uruzitiro rwa TPU rurerure rubuza amazi y'imvura kwinjira kandi rutuma ibintu by'imbere biguma byumye;
- Irwanya kwangirika no gushwanyagurika: Ikubye kabiri ubudahangarwa bwa PVC, nta gushwanyagurika cyangwa kwera nyuma yo gukurura imikandara yo ku kibuga cy'indege kenshi;
- Ubushobozi bwo guhangana n'ingaruka: Ikira vuba nyuma yo gukandamizwa, yirinda guhindagurika burundu mu gihe cyo gusohoka mu ndege;
- Igishushanyo cyoroheje: 25% ~ 30% byoroheje kurusha ibindi bikoresho by'uruhu nyarwo bifite imbaraga zimwe, bihuye n'ibigezweho byo gutwaramo byoroheje.
1.3 Ikoranabuhanga ryo Gutunganya
Ifu yumye idashonga ifite ubushyuhe buri munsi ya 180 ~ 220°C, ikoreshwa mu gukaraba imizigo mu buryo bwa VOC nkeya ikurikije amahame ngenderwaho y’ibidukikije ya EU; iboneka mu buryo butagaragara, bubengerana kandi bworoshye ku miyoboro y’imizigo ihenze.
2. Umuzigo w'ibikoresho bikomeye: TPU Film Lamination kuri PC Shells
Filimi ya TPU ifite uburebure bwa 0.1 ~ 0.2 mm ishyirwa ku gipimo cy'ubushyuhe kuri paneli zikomeye za PC / ABS kugira ngo isubize ibibazo bya mudasobwa isanzwe:
- Irwanya gushwanyagurika no gushotora: Imitako yo hanze ya TPU igabanya ingaruka kandi ikagabanya uburebure bw'umusuko wo hejuru ho hejuru ya 60%;
- Irwanya umuhondo hamwe na UV stabilizer: Irwanya gusaza no kugorama iyo imaze igihe kinini ihura n'izuba;
- Ahantu hadashyirwamo ibitoki kandi hakosorwa neza: Gukuraho ibizinga by'amavuta n'ibikumwe ako kanya, imiterere isanzwe y'udusanduku tw'ubucuruzi dukomeye.
Gutunganya: Shyushya ikibaho cyo hasi gikurikirwa na lamination ishyushye cyane, ikoreshwa cyane n'ibigo bikomeye birimo RIMOWA na 90 Points.
3. Ibice by'imizigo ya TPU yo guterwamo inshinge n'iy'umushongi
3.1 Igitambaro cya Caster (Ibikoresho Bikunze Kuboneka)
- 90~95A polyester ikomeye cyane TPU: Amapine akomeye yo kugenzura, igihe cyo gukora kiruta inshuro 4~5 amapine ya TPE, adashobora kwangirika ku mabuye y'agaciro n'inzira z'ikibuga cy'indege;
- 80~85A TPU yoroshye yahinduwe: Amasasu adatuje kandi afite urusaku ruto afite amaberari, urusaku rugenda rugenzurwa kuri 40~50 dB ku mizigo idasanzwe idatuje.
3.2 Imikoki & Urusobe rw'amatafari rukozwe mu buryo bwa Overmolded
- Ubuso bwa TPU bukozwe neza: Ubuso bwa TPU bukozwe neza bukuraho amazi akura kandi bugatera ubwivumbure, ibikoresho bigezweho byo gukoresha imishumi y'intoki n'imishumi y'ibitugu bisimbura ubuso busanzwe bw'imyenda;
- Gufata TPU ifite igice kimwe cyoroshye: Ingufu nyinshi zo gusubira inyuma mu gihe cyo kunanirwa gucika mu gihe cy'umutwaro uremereye.
3.3 Ibice byo Gufunga no Guteka
- Kaseti ya TPU idapfa amazi yo gufata zipu: Ifunze neza kugira ngo ifunze icyuho cya zipu kandi ikoreshwe mu buryo bwuzuye;
- TPU ifite ifuro rya microcellular ku mabumpers yo mu mfuruka no ku dupapuro tw’imbere two gushoka: Yoroshye kandi irakomeye, irinda impande z’imizigo n’ibintu by’agaciro biri imbere;
- Udupira twa TPU twihanganira impanuka two gukoresha udupira two gukurura: Tugabanya gutitira no kunyeganyega kw'udupira twa telesikope.
4. Kugereranya amahitamo:Polyester vs Polyether TPU
表格
| Icyiciro | Ibyiza by'ingenzi | Ubwoko bw'imizigo ikoreshwa |
|---|---|---|
| Polyester TPU | Gushwanyagurika cyane, kudakoresha amavuta n'imbaraga za mekanike | Gukoresha kenshi mu kazi ko kugenzura imizigo n'amasasu |
| Polyether TPU | Ubudahangarwa bwa hydrolysis no koroherwa n'ubushyuhe buri hasi | Imifuka yo hanze n'imizigo yo mu rugo yo mu turere duhehereye cyane |
5. Incamake y'Ibyiza n'Ibibi
Ibyiza
- Birinda ibidukikije: Nta phthalate kandi nta halogen, bishobora kongera gukoreshwa mu bushyuhe, biruta PVC n'uruhu rusanzwe rwa PU;
- Guhangana n'imihindagurikire y'ikirere mu buryo burambuye: Ingufu zihamye kuva kuri -35°C kugeza kuri 70°C, nta guhindagurika kw'ikirere hagati y'impinduka zikomeye z'ubushyuhe n'ubwikorezi bwo mu nyanja buri kure;
- Uburyo bwo gushushanya: Inyongera mu mifuka irwanya udukoko, igabanya umuriro cyangwa igabanya ubukana bw'imizigo y'ababyeyi n'abana ndetse n'iy'ibikoresho byihariye.
Imbogamizi
Igiciro cy'ibikoresho fatizo kiri hejuru ya 25% ~ 35% ugereranyije na PVC na PU isanzwe, kandi gikunze gukoreshwa mu buryo bwuzuye ku mizigo ihendutse.
6. Icyerekezo cy'iterambere ry'inganda
- TPU ishingiye ku binyabuzima (ibikomoka ku mavuta y'ibimera): Ibikoresho bidafite karuboni nyinshi bikorerwa ku bidukikije byamamajwe n'ibigo mpuzamahanga bikomeye by'imizigo kugira ngo bikoreshwe mu buryo butangiza ibidukikije;
- Filimi ya TPU yivura ubwayo: Gusana iminkanyari yo ku buso bwiza
