Kev tsim cov ntawv thov ntawm Thermoplastic Elastomers

Yog tias koj tab tom yuav khoom rau lub xov tooj smartphone, koj cov khoom xaiv feem ntau yog silicone, polycarbonate, tawv yas, thiab thermoplastic polyurethane (TPU).Yog tias koj xav paub tias TPU yog dab tsi, peb yuav rhuav tshem nws (pom zoo).

Dab tsi yog thermoplastic?
Raws li koj paub, yas yog cov khoom siv hluavtaws (feem ntau) ua los ntawm hluavtaws polymers.Lub polymer yog cov khoom tsim los ntawm monomers.Monomer molecules tsim cov saw ntev nrog lawv cov neeg nyob ze, tsim cov macromolecules loj.

Plasticity yog cov cuab yeej uas muab yas nws lub npe.Yas tsuas txhais tau tias cov khoom siv tuaj yeem deformed mus tas li.Cov yas tuaj yeem hloov kho los ntawm molding, squeezing los yog siv lub siab.

Thermoplastics tau txais lawv lub npe los ntawm lawv cov lus teb rau cov cua sov.Cov thermoplastics dhau los ua yas ntawm qee qhov kub, uas yog, thaum lawv zoo li qhov xav tau.Thaum lawv txias lawm, lawv cov duab tshiab tuaj yeem mus tas li kom txog thaum lawv rov ua kom sov dua.

Qhov kub uas yuav tsum tau ua kom lub thermoplastic hloov tau ntau dua li qhov koj lub xov tooj tuaj yeem tiv taus.Yog li, cov khoom siv thermoplastic hardly deform thaum siv ib txwm.

Fused Deposition Modeling 3D tshuab luam ntawv yog cov tshuab luam ntawv 3D ntau tshaj plaws hauv khw niaj hnub no thiab siv cov thermoplastics.Yas filaments yog pub los ntawm extruder, thiab lub tshuab luam ntawv txheej txheej nws cov khoom, uas cools thiab solidifies sai heev.

Yuav ua li cas yog polyurethane?
Polyurethane (PU) yog hais txog ib chav kawm ntawm cov organic polymers txuas los ntawm polyurethane bonds."Organic" nyob rau hauv cov ntsiab lus no yog hais txog cov organic chemistry nyob rau hauv cov ntsiab lus carbon.Carbon yog lub hauv paus ntawm lub neej raws li peb paub, yog li lub npe.

Ib qho ntawm cov khoom uas ua rau polyurethane tshwj xeeb yog tias nws tsis yog ib qho kev sib xyaw tshwj xeeb.Polyurethanes tuaj yeem tsim los ntawm ntau hom monomers.Yog vim li cas nws yog chav kawm ntawm polymers.
