Yu thiab TPU Hotmelt rau cov khau shooemaking

 

 

Qhov no yog ib qho ntawm feem ntau siv kub qhuav cov nplaum rau khau. Eva kub yaj nplooj yog cov kuab tshuaj nplaum dawb me me, ntxiv cov khoom siv ethylene-vinyling-vinyling-vinyling-vinyled Nws muaj qhov zoo ntawm cov tsis muaj tshuaj lom, tsis muaj kev muaj kuab paug ib puag ncig, thiab npaj tau yooj yim. Nws yog dav siv nyob rau hauv rooj tog, shoemaking, electronics thiab lwm yam kev lag luam. ‌

Eva kub yaj nplaum muaj cov cohesion muaj zog thiab cov av tsis muaj zog loj. Nws muaj cov kua nplaum kub relay rau yuav luag txhua yam tshuaj thiab muaj cov tshuaj tsis zoo, thermal tsis kam thiab hluav taws xob. Feem ntau siv hauv khau vamp thiab nraub qaum

 

 

Vim li cas tpu kub yaj lo nplaum zaj duab xis xav tau rau khau cov khoom sib raug zoo?

Cov kev ua TSHUAB Shoemakaking tshuab kev sib hlub ntawm cov kua nplaum uas muaj cov kua nplaum xws li vocs muaj kuab paug, tsis sib xws lub zog, thiab kev laus tsis zoo. TPU Kub Kub Qhuav Zaj Duab Xis tau dhau los ua khau uas tsis muaj khau khiab Nws yog qhov tshwj xeeb tshaj yog tsim nyog rau cov khoom sib xyaw ua ke xws li ya davhlau, EVA Midsoles, thiab cov roj hmab outoles.

 

Tsib lub ntsiab lus zoo ntawm tpu kub yaj adhesive zaj duab xis

1. Super Hydrolysis tsis muaj zog tiv thaiv kom tiv nrog ib puag ncig loj

Cov ntaub ntawv TPU tseem tswj hwm ntau dua 90% kev sib koom ua lub zog, hloov cov teeb meem ntawm cov khau txheej debonding.

Cov ntaub ntawv: Tom qab muaj qee hom sab nraum zoov ntawm cov khau khiab TPU adhesive zaj duab xis, ntsev txau lub neej yog txuas ntxiv los ntawm 3 zaug

2. Siab elasticity ntais ntawv tsis sib xws

Hardness is adjustable, elongation>500%, thiab nws tuaj yeem tiv taus 100,000 khoov tsis muaj delamination (Astm D430 txuj).

Daim Ntawv Thov Kev Ua Yeeb Yam: Cov teeb meem zoo ntawm kev khiav khau sab saud thiab midsole

3. Kev ntsuas kub kho kom tiv thaiv kom tiv thaiv cov ntaub ntawv rhiab

Melting point range **110℃-140℃**, lower than the deformation temperature of EVA foam material (usually >150 degree), zam kev kub thiab kev puas tsuaj siab.

4. Ib puag ncig ua raws, ntsib cov qauv xa tawm

Dhau mus txog thiab FDA Cov zaub mov noj zaub mov zoo, raug yoog rau EU Footwear ib puag ncig (2023 / XX / EU).

5. Revolution Hauv Cov Txheej Txheem Ua Haujlwm

Lub sijhawm nias kub nias tsuas yog siv 5-15 vib nas this, uas yog 80% sai dua li cov txheej txheem xim nplaum tso cai thiab txo cov nqi siv hluav taws xob.

 

Qhov tseem ceeb Daim Ntawv Qhia Txog TPU zaj duab xis hauv khau cov khoom sib xyaws

Khau hom / Part Yut daws qhov ntsuas ntsuas

Sports shoe flying woven upper 0.2mm transparent TPU film seamless bonding Air permeability>3000g/m²/24h

Safety shoe steel toe cover 1.5mm flame retardant TPU film (UL94 V-0) Peel strength>8n / hli

Snow boots waterproof stitching Low temperature resistant -40℃ TPU film Ice surface adhesion retention rate>85%

Cov khau khiab Eva Nruab Nrab thiab Tsawg Composite Gellow Distant UV Qib TPU Zaj Duab Xis<2 after 300h UV aging

 

Khau Qhia Khau Hoobkas Xaiv: 4 kauj ruam kom phim qhov zoo tshaj plaws TPU zaj duab xis

1. Substrate Ntsuas Xyuas

- ya cov ntaub thaiv / PU Tawv PU: Xaiv cov khoom me me: Xaiv cov ntsiab tsawg (110-120 degree) pob tshab tpu

- Roj Hmab / TPU Outsole: Siv HarTness Roj Resistant Hom

2. Thickness thiab yuag xaiv

- Nyias sab saud: 0.1-0.3mm (hnyav 30-60g / ㎡)

- Cov khau ua haujlwm hnyav: 0.5-1.0 hli (phaus 80-150G / ㎡)

3. Yuav Tsum Tau Ua

- Nkawm khau sab nraum zoov: Hydrolysis Kuj / UV qib yuav tsum tau ua

- Cov menyuam yaus nkawm menyuam: Yuav tsum muaj cov ntawv qhia zaub mov hu tau

4. Cov ntaub ntawv pov thawj txheej txheem

- Cov xovxwm kub: Qhov kub ua yuam kev ± 3 degree, siab 0.3-0.8MPA

- Nws raug nquahu kom ua 48h ntub cua kub laus (85℃/ 85% rh) simulation kuaj ua ntej
