Iine hunhu hwakanaka hunosanganisira kuramba kukwesha zvakanyanya, kusachinjika kwakanyanya, kushanda zvakanaka kwemvura, kusimba kwekupisa kwakaderera, kuvharika kwekupisa uye hushamwari kune zvakatipoteredza kuti zvidzokororwe, TPU inogadzirwa neYantai Linghua New Material Co.,Ltd.Inoshandiswa zvakanyanya mumikwende yepakati kusvika yepamusoro-soro munzvimbo nhatu huru dzekushandisa: machira akapfava, chifukidziro chepamusoro chemikwende yakaoma uye zvishandiso zvinoshanda zvakaumbwa nejekiseni.
1. Mitoro Yakapfava:TPUMachira Akarapwa (Chikamu Chikuru Chekushandisa)
1.1 Chimiro Chehwaro
Jira repolyester kana nylon oxford rakanamirwa nefirimu reTPU re 0.08~0.4 mm kuburikidza nekudzvanya kwekupisa, rakakamurwa kuita TPU yakavakirwa papolyester uye TPU yakavakirwa papolyester:
- Polyester TPU: Inodzivirira kukweshwa kwakanyanya uye mafuta, yakasimba pakukwesha uye kubvaruka (≥8 N/cm), yakakodzera kunyoreswa kwemukwende webhizinesi;
- Polyether TPU: Inodzivirira hydrolysis zvakanaka, inoramba yakachinjika kusvika -30°C isina kuoma, inofarirwa pakutakura mikwende yekunze uye kure.
1.2 Mabhenefiti Akakosha Ekushanda
- Mvura isingapindi mvura zvachose: Chidziviriro chakasimba cheTPU chinodzivirira mvura kupinda uye chinoita kuti zvinhu zvemukati zviome;
- Inodzivirira kukwenya nekukwenya: Inodzivirira kukwenya nekuwedzera kaviri PVC, haibvi kana kucheneswa mushure mekudhonzwa kakawanda pamabhande ekufambisa ndege;
- Kugona kusimba kwesimba: Inopora yega mushure mekumanikidzwa, ichidzivirira kushanduka zvachose panguva yekubuda kwemhepo mundege;
- Dhizaini yakareruka: 25% ~ 30% yakareruka kupfuura dzimwe nzira dzeganda chairo dzine simba rakafanana, zvichienderana nefashoni yekutakura yakareruka.
1.3 Tekinoroji Yekugadzirisa
Lamination yakaoma isina solvent pasi pe180~220°C inopisa, ine VOC shoma inoenderana nezvinodiwa neEU zvekutakura zvinhu; inowanikwa mumhando dzakapfava, dzinopenya uye dzakapfava dzekutakura zvinhu zvemhando yepamusoro.
2. Mutoro Wakaoma: TPU Film Lamination paPC Shells
Firimu reTPU re 0.1 ~ 0.2 mm rinonamirwa paPC/ABS hard panels kuti ritsive matambudziko aripo ePC yakachena:
- Kudzivirira kukwenya nekuvhunduka: Makusheni ekunze eTPU anodonhedza simba uye anoderedza kudzika kwekukwenya pamusoro neanopfuura 60%;
- Inodzivirira kutsvuka kweruvara rweUV: Inodzivirira kukwegura uye kuputsika kana ikabatwa nezuva kwenguva refu;
- Nzvimbo isingapindi minwe uye iri nyore kupukuta: Kubviswa ipapo ipapo kwemavara emafuta neminwe, magadzirirwo akajairwa emakesi akaomarara ebhizinesi repamusoro.
Kugadzira: Preheat base board ichiteverwa nehot-press lamination inodziya zvakanyanya, inoshandiswa zvakanyanya nemakambani makuru anosanganisira RIMOWA ne90 Points.
3. Zvikamu zveTwee zveTPU zveJekiseni & Extruded
3.1 Caster Tread (Chishandiso Chinonyanya Kushandiswa)
- 90~95A polyester yakasimba TPU: Mavhiri anorema ekutarisa mukati, nguva yekushanda yakareba ka4~5 kupfuura mavhiri eTPE, anodzivirira kukweshwa pamatombo nepanzira dzendege;
- 80~85A TPU yakapfava yakagadziriswa: Ma "casters" akanyarara ane ruzha rushoma ane mabheringi, ruzha runomhanya runodzorwa pa40~50 dB yekutakura zvinhu zvisina ruzha zvepamusoro.
3.2 Mibato & Overmolded Webbing
- TPU yakaumbwa zvizere: Kuvhara kweTPU kwakabatana kunobvisa kunyungudika kwemvura uye kunyorova, zvinhu zvakagadziridzwa zvemabhandi emaoko nemabhandi emafudzi zvichitsiva machira echinyakare;
- Kubata ruoko kweTPU kunochinjika nechidimbu chimwe chete: Simba guru rekudzokesa simba rinodzivirira kutyoka kana mutoro wakawanda wava kuremerwa.
3.3 Zvikamu zveKuvhara & Kutsigira
- Tepi inonamira yeTPU isingapindi mvura yemazipi: Inopisirwa nekupisa kuti ivhare mipata yezipi uye iite kuti mvura isapinde mubhokisi rese;
- TPU ine furo re microcellular rema corner bumpers nema inner shock pads: Yakareruka uye yakasimba, inodzivirira makona emidziyo nezvinhu zvinokosha zviri mukati;
- Magorometi eTPU anobata kuvhunduka ekushandisa tsvimbo dzekudhonza: Deredza kurira uye kudedera kwemibato yetelescopic.
4. Kuenzanisa Sarudzo:Polyester vs Polyether TPU
表格
| Giredhi | Zvakanakira Zvikuru | Rudzi rweMitoro Rinoshanda |
|---|---|---|
| Polyester TPU | Kukwesha kwakanyanya, kuramba mafuta uye simba remakanika | Mitoro nemidziyo yekuisa zvinhu mubhizinesi inogaroshandiswa kakawanda |
| Polyether TPU | Kuramba hydrolysis & kuchinjika kwekupisa kwakaderera | Mabhegi ekunze emusana nemabhegi ekunze enzvimbo dzine hunyoro hwakawanda |
5. Pfupiso yeZvakanakira & Zvakaipa
Zvakanakira
- Inoshamwaridzana nezvakatipoteredza: Haina Phthalate uye haina halogen, inogona kudzokororwa pakupisa, iri nani pane PVC uye dehwe rePU rakajairika;
- Kuchinjika kwakakura kwemamiriro ekunze: Kushanda kwakagadzikana kubva -35°C kusvika 70°C, hapana kuchinja kwemamiriro ekunze pakati pekuchinja kukuru kwekushisa uye ngarava dziri kure mugungwa;
- Mushonga unogadziriswa: Zvinowedzerwa pakurapa mabhakitiriya, zvinodzivisa moto kana kuti zvinodzivirira static grades zvemai nemwana uye zvemikwende yakakosha.
Zvakashata
Mutengo wezvinhu zvisina kugadzirwa wakakwira ne25% ~ 35% kupfuura PVC nePU yemazuva ano, hauwanzo shandiswa mukuvhara zvizere mitoro isingadhuri zvakanyanya.
6. Maitiro eKuvandudza Maindasitiri
- TPU inobva mumiti (yakagadzirwa nemafuta emiti): Zvinhu zvisina kabhoni yakawanda zvinosimudzirwa kuti zvishandiswe muzvigadzirwa zvisingakuvadzi nharaunda nemakambani makuru ekutakura zvinhu pasi rose;
- Firimu reTPU rinozvirapa: Kugadzirisa mavanga akanaka pamusoro
