Yuav ua li cas txo lub hardness thiab txhim kho qhov kev tua tuag tsis kam ntawm TPU cov granule?

3. Yuav ua li cas sib cais-tiv taus fillers

Txhawm rau txhim kho cov kws muaj txuj ci tseem ceeb, cov kws txawj xav tau ua ke zoo li carbon dub, iav fibers, los yog silicone masterbatch, lossis silicone dioxide. Cov fillers no tuaj yeem txhawb nqa TPU lub zog-resistance cov yam ntxwv.

Txawm li cas los xij, kev txiav txim siab ua tib zoo xav tau muab rau kom muaj nuj nqis thiab dispersion ntawm cov fitters, uas yog qhov ntau dhau yuav cuam tshuam cov khoom siv tau yooj yim.

4. Cov tshuab raj thiab cov khoom siv muag khoom

Raws li txoj kev los txo cov tawv tawv TPU Hardness, TPU cov tuam txhab yuav siv cov khoom siv lossis cov neeg sawv cev. Nws yog ib qho tseem ceeb kom xaiv cov plia kom haum uas tuaj yeem qis dua tsis muaj kev sib txawv tsis muaj kev sib txawv. Cov roj hmab sib xyaw siv nrog TPU suav nrog Dioctyl phthalate (DOP) thiab Dioctyl supipate (doa). Kev saib xyuas yuav tsum tau ua kom ntseeg tau tias cov roj hmab xaiv tau sib xws nrog TPU thiab tsis cuam tshuam lwm yam xws li tensile lub zog lossis tshuaj lom neeg. Tsis tas li ntawd, cov koob tshuaj tivthaiv ntawm cov yas ua kom muaj kev tswj hwm kom tswj tau qhov kev xav tau.

5. Nplua-tuning extrusion thiab kev ua tsis taus

Kho kom haum rau cov tshuaj tsis sib xws yog tseem ceeb nyob rau hauv kev ua tiav qhov kev xav tau ntawm kev txo qis hardness thiab txhim kho puas tsuaj tsis kam. Qhov no entails hloov kho qhov ntsuas kub thiab kub, thiab cov nqi txias thaum lub sijhawm extrusion.

Txo cov kev siv hluav taws xob kub thiab ua tib zoo ua kom txias dua tuaj yeem ua rau softer tpu thaum ua kom cov dispersion ntawm kev puas tsuaj-tiv taus fillers.

6. Kev ua haujlwm tom qab ua tiav

Cov txheej txheem tom qab ua zoo li annealing, ncab, lossis txawm tias kev kho mob saum npoo av uas tsis muaj kev nyuaj siab.

Annealing, tshwj xeeb, tuaj yeem txhim kho cov qauv crystalline ntawm TPU, ua rau nws tiv thaiv ntau dua thiab kua muag.
