Hnyeeb-based TPU Adhesive Zoo Viscosity
Hais Txog TPU
TPU (thermoplastic polyurethanes) txuas hniav cov khoom sib txawv ntawm cov ntxiab thiab plastics. Nws cov khoom siv lub cev muaj zog ua haujlwm rau siv los ua ob qho nyuaj roj hmab thiab cov khoom siv muag hluav taws xob thiab muaj txiaj ntsig zoo, kev nplua nuj thiab muaj txiaj ntsig ntawm lwm cov txiaj ntsig. Ib qho ntxiv, lawv yooj yim rau cov txheej txheem.
Raws li cov ntaub ntawv tawm tshiab thiab ib puag ncig-cov ntaub ntawv ua haujlwm, ib puag ncig zoo, muaj zog ua haujlwm, muaj zog tshaj, cov dej tsis kam.
Daim ntawv thov
Cov Kev Siv: Cov qauv nplaum, kub-melt nplaum cov yeeb yaj kiab, cov khoom nplaum khau.

Lub thawv
25kg / hnab, 1000kg / pallet lossis 1500kg / pallet, cov txheej txheem yas pallet
Xuas Thiab Cia
1. Zam kev ua pa thermal ua cov pa ntxig thiab cov vapors
2. Neeg kho tshuab tuav cov khoom tuaj yeem ua rau muaj plua plav. Tsis txhob ua pa ua pa.
3.. Siv cov txuj ci tsim kom zoo thaum daws cov khoom no kom tsis txhob muaj kev them nyiaj hauv electrostatic
4. Pellets nyob rau hauv pem teb yuav nplua thiab ua rau poob
Cov Lus Taw Qhia Cia: Yuav kom muaj cov khoom lag luam zoo, khaws cov khoom lag luam hauv qhov chaw txias, qhuav. Khaws cia hauv cov thawv kaw ntom ntom.
Sau ntawv
1. Deteriorated TPU cov ntaub ntawv tsis tuaj yeem siv rau cov khoom lag luam.
2. Ua ntej molding, nws yog ib qho tsim nyog kom qhuav, tshwj xeeb tshaj yog thaum cov khoom moulding, nrog cov txheej txheem moulding, tshwj xeeb tshaj yog nyob rau hauv cov caij dav dav, cov av noo thiab cov av noo.
3. Lub sijhawm tsim khoom, tus qauv, Compression sib piv, zawv ib yam kev sib tw L / D ntawm cov ntsia hlau yuav tsum raug txiav txim siab raws li cov yam ntxwv ntawm cov khoom. Txhaj tshuaj molding cov screws yog siv rau kev txhaj tshuaj moulding, thiab extrusion screws yog siv rau extrusion.
4. Raws li cov fluidity ntawm cov khoom, xav txog cov pwm qauv, qhov loj me, ntsuas cov qauv channel, thiab txoj haujlwm ntawm kev tso pa.
