Cov kua nplaum TPU uas muaj cov kuab tshuaj zoo viscosity
txog TPU
TPU (thermoplastic polyurethanes) txuas qhov sib txawv ntawm cov khoom siv ntawm roj hmab thiab yas. Nws cov yam ntxwv ntawm lub cev ua rau TPU siv tau ua ob qho tib si roj hmab tawv thiab thermoplastic engineering mos. TPU tau ua tiav kev siv dav dav thiab nrov hauv ntau txhiab yam khoom, vim lawv lub zog ruaj khov, mos thiab xim zoo nkauj ntawm lwm yam txiaj ntsig. Tsis tas li ntawd, lawv yooj yim rau kev ua.
Ua ib qho khoom siv thev naus laus zis siab thiab zoo rau ib puag ncig, TPU muaj ntau yam khoom zoo heev xws li qhov nyuaj dav, lub zog siab, tiv taus txias, ua haujlwm tau zoo, puas tsuaj rau ib puag ncig, tsis kam roj, tsis kam dej thiab tsis kam pwm.
Daim Ntawv Thov
Daim Ntawv Thov: Cov Nplaum Uas Muaj Cov Tshuaj Kuab, Cov Yeeb Yaj Kiab Uas Muaj Cov Tshuaj Kub, Cov Nplaum Khau.

Cov nqi saum toj no tau qhia ua cov nqi ib txwm muaj thiab yuav tsum tsis txhob siv ua cov lus qhia.
Pob khoom
25KG/hnab, 1000KG/pallet los yog 1500KG/pallet, ua tiav yas pallet
Kev Tswj thiab Kev Khaws Cia
1. Tsis txhob ua pa cov pa luam yeeb thiab cov pa dej uas ua los ntawm cov khoom siv cua sov
2. Cov khoom siv kho tshuab ua rau muaj hmoov av. Tsis txhob ua pa plua plav.
3. Siv cov txheej txheem av kom raug thaum tuav cov khoom no kom tsis txhob muaj cov nqi hluav taws xob electrostatic
4. Cov khoom me me hauv pem teb yuav nplua thiab ua rau ntog
Cov lus qhia txog kev khaws cia: Yuav kom cov khoom zoo, khaws cia rau qhov chaw txias thiab qhuav. Khaws cia rau hauv lub thawv kaw ruaj ruaj.
Cov Lus Cim
1. Cov ntaub ntawv TPU uas puas lawm tsis tuaj yeem siv los ua cov khoom.
2. Ua ntej molding, nws yog ib qho tsim nyog kom qhuav tag, tshwj xeeb tshaj yog thaum lub sijhawm extrusion molding, blow molding, thiab film blowing molding, nrog rau cov kev cai nruj dua rau cov dej noo, tshwj xeeb tshaj yog nyob rau hauv lub caij noo noo thiab thaj chaw noo noo.
3. Thaum lub sijhawm tsim khoom, cov qauv, qhov sib piv ntawm qhov sib txuas, qhov tob ntawm qhov sib txuas, thiab qhov sib piv ntawm L/D ntawm lub hau yuav tsum tau txiav txim siab raws li cov yam ntxwv ntawm cov khoom siv. Cov ntsia hlau txhaj tshuaj molding siv rau kev txhaj tshuaj molding, thiab cov ntsia hlau extrusion siv rau kev extrusion.
4. Raws li qhov ua tau ntawm cov khoom siv, xav txog cov qauv pwm, qhov loj ntawm qhov nkag ntawm cov kua nplaum, qhov loj ntawm lub nozzle, cov qauv ntawm cov dej ntws, thiab qhov chaw ntawm qhov chaw tso pa tawm.
