Solvent-Based TPU nplaum zoo viscosity
txog TPU
TPU (thermoplastic polyurethanes) txuas cov khoom sib txawv ntawm cov roj hmab thiab cov yas. Nws ntau yam ntawm lub cev muaj zog ua rau TPU siv los ua cov roj hmab tawv thiab cov khoom siv hluav taws xob zoo nkauj.TPU tau ua tiav kev siv dav thiab muaj koob npe nyob hauv ntau txhiab cov khoom, vim lawv cov kav ntev, softness thiab colorability ntawm lwm cov txiaj ntsig. Tsis tas li ntawd, lawv yooj yim rau txheej txheem.
Raws li cov khoom siv high-tech thiab ib puag ncig-phooj ywg, TPU muaj ntau yam khoom zoo heev xws li dav hardness ntau yam, siab mechanical zog, zoo heev tiv taus, kev ua tau zoo, ib puag ncig tus phooj ywg degradation, roj kuj, dej tsis kam thiab pwm kuj.

25KG / hnab, 1000KG / pallet lossis 1500KG / pallet, txheej txheem yas pallet
Kev tuav thiab khaws cia
1. Tsis txhob ua pa cua sov ua pa thiab vapors
2. Cov cuab yeej siv kho tshuab tuaj yeem ua rau muaj plua plav. Tsis txhob ua pa plua plav.
3. Siv cov txheej txheem hauv av kom zoo thaum tuav cov khoom no kom tsis txhob muaj cov nqi hluav taws xob electrostatic
4. Cov pellets nyob rau hauv pem teb yuav nplua thiab ua rau ntog
Cov lus pom zoo khaws cia: Txhawm rau khaws cov khoom zoo, khaws cov khoom hauv qhov chaw txias, qhuav. Khaws rau hauv ib lub thawv kaw nruj nreem.
Sau ntawv
1. Cov ntaub ntawv tsis zoo TPU tsis tuaj yeem siv los ua cov khoom lag luam.
2. Ua ntej molding, nws yuav tsum tau qhuav tag, tshwj xeeb tshaj yog thaum lub sij hawm extrusion molding, tshuab molding, thiab zaj duab xis tshuab moulding, uas yuav tsum nruj me ntsis rau cov ntsiab lus ntawm noo noo, tshwj xeeb tshaj yog nyob rau hauv lub caij ntuj sov thiab high humidity.
3. Thaum lub sij hawm tsim khoom, tus qauv, compression piv, groove qhov tob, thiab nam piv L / D ntawm cov ntsia hlau yuav tsum raug txiav txim siab raws li cov yam ntxwv ntawm cov khoom. Txhaj tshuaj molding screws yog siv rau kev txhaj tshuaj molding, thiab extrusion screws yog siv rau extrusion.
4. Raws li qhov fluidity ntawm cov khoom, xav txog cov qauv pwm, qhov loj ntawm cov kua nplaum inlet, nozzle loj, ntws channel qauv, thiab txoj hauj lwm ntawm qhov chaw nres nkoj.
