Yuav ua li cas kom txo tau lub hardness thiab txhim khu lub abrasion Resistance ntawm TPU Granule?

3. Incorporating Abrasion-Resistant Fillers

Txhawm rau txhim kho kev puas ntsoog, cov kws tshaj lij pom zoo kom muab cov khoom ntim tshwj xeeb xws li carbon dub, iav fibers, silicone masterbatch, lossis silicon dioxide. Cov Fillers no tuaj yeem txhawb nqa TPU cov khoom hnav-tiv taus.

Txawm li cas los xij, ua tib zoo saib xyuas yuav tsum tau muab rau kom muaj nuj nqis thiab dispersion ntawm cov fillers, vim tias qhov ntau dhau yuav cuam tshuam rau cov khoom hloov pauv.

4. Plasticizers thiab Softening Agents

Raws li ib txoj kev los txo TPU hardness, TPU Manufacturers yuav siv cov yas los yog softening agents. Nws yog ib qho tseem ceeb uas yuav tau xaiv ib tug haum plasticizer uas yuav txo tau hardness yam tsis muaj kev puas tsuaj rau puas. Cov yas yas siv nrog TPU suav nrog dioctyl phthalate (DOP) thiab dioctyl adipate (DOA). Kev saib xyuas yuav tsum tau ua kom ntseeg tau tias cov yas uas tau xaiv yog sib xws nrog TPU thiab tsis cuam tshuam rau lwm yam khoom xws li tensile zog lossis tshuaj tiv thaiv. Tsis tas li ntawd, ntau npaum li cas ntawm plasticizers yuav tsum tau ua tib zoo tswj kom muaj qhov sib npaug xav tau.

5. Fine-Tuning Extrusion thiab kev ua tsis tau

Kho extrusion thiab kev ua tsis tau yog qhov tseem ceeb hauv kev ua tiav qhov xav tau ua ke ntawm kev txo qis hardness thiab txhim kho kev puas tsuaj. Qhov no suav nrog kev hloov pauv tsis zoo li qhov kub thiab txias, siab, thiab cua txias thaum lub sijhawm extrusion.

Tsawg extrusion kub thiab ceev ceev txias yuav ua rau softer TPU thaum optimizing dispersion ntawm abrasion-resistant fillers.

6. Cov txheej txheem tom qab ua tiav

Cov txheej txheem tom qab ua tiav zoo li annealing, ncab, lossis txawm tias kev kho saum npoo tuaj yeem txhim kho kev puas tsuaj ntxiv yam tsis muaj kev cuam tshuam qhov nyuaj.

Annealing, tshwj xeeb, tuaj yeem txhim kho cov qauv crystalline ntawm TPU, ua rau nws tiv taus hnav thiab tsim kua muag.
