Thermoplastic Elastomers (TPE) thiab Thermoplastic Polyurethanes (TPU)
TPE (Thermoplastic Elastomer) thiab TPU (Thermoplastic Polyurethane) yog ob qho khoom siv polymer uas siv dav hauv cov ntawv thov uas xav tau elasticity, yooj, thiab kav ntev. Hauv qab no yog cov ncauj lus ntxaws ntxaws ntawm cov ntaub ntawv no:
Thermoplastic Elastomers (TPE)
Txhais:
TPEs yog ib chav kawm ntawm copolymer los yog lub cev sib xyaw ntawm cov polymers (feem ntau yog cov yas thiab roj hmab) uas muaj cov khoom siv nrog ob qho tib si thermoplastic thiab elastomeric zog. Lawv pom cov roj hmab zoo li elasticity ntawm chav tsev kub tab sis tuaj yeem ua tiav raws li cov yas thaum rhuab.
Yam ntxwv:
Elasticity: TPEs muaj qhov elasticity siab thiab tuaj yeem rov qab mus rau lawv cov qauv qub tom qab deformation.
Kev ua tau zoo: Lawv tuaj yeem ua tiav rau hauv cov duab nyuaj siv txoj hauv kev xws li txhaj tshuaj molding, extrusion, thiab tshuab molding.
Kev rov ua dua tshiab: Ua cov thermoplastic, lawv tuaj yeem rov ua dua, txo cov khoom pov tseg.
Huab cua Resistance: TPEs nthuav tawm huab cua zoo, suav nrog kev tiv thaiv UV thiab ozone.
Softness thiab Xav: Ntau TPEs muaj qhov muag muag, ua rau lawv haum rau kev tuav thiab cov khoom muag muag.
Daim ntawv thov:
Cov khoom siv kho mob, cov khoom siv tsheb, cov khoom siv hluav taws xob siv hluav taws xob, cov khoom ua si, khoom siv kis las, thiab lwm yam.
Thermoplastic Polyurethanes (TPU)
Txhais:
TPU yog ib hom TPE muaj li ntawm polyurethane. Nws paub txog nws cov elasticity siab, hnav tsis kam, thiab tshuaj lom neeg ua haujlwm.
Yam ntxwv:
High Elasticity thiab hnav tsis kam: TPUs yog cov resistant rau abrasion, haum rau high-hnav daim ntaub ntawv.
Roj thiab tshuaj tiv thaiv: Lawv muaj kev tiv thaiv zoo rau cov roj, roj, thiab ntau yam tshuaj.
Pob tshab: Qee TPUs tuaj yeem ua pob tshab lossis ib nrab pob tshab, haum rau cov ntawv thov uas xav tau cov ntaub ntawv ntshiab.
Ntau yam ntawm Hardness: Lub hardness ntawm TPU tuaj yeem hloov kho los ntawm cov roj hmab muag zoo li cov yas tawv los ntawm kev hloov cov qauv.
Biocompatibility: Qee TPUs muaj biocompatibility zoo, ua rau lawv haum rau kev siv kho mob.
Daim ntawv thov:
Cov khau khau, hoses, cable tsho, cov khoom lag luam, cov khoom ua si, cov khoom siv kho mob, cov xov tooj, thiab lwm yam.
Kev sib piv ntawm TPE thiab TPU
Elasticity thiab Flexibility:
TPEs feem ntau softer thiab muaj kev xav zoo dua, haum rau cov ntawv thov xav tau siab softness.
TPUs ua tau zoo nyob rau hauv siab elasticity thiab hnav tsis kam, zoo tagnrho rau ntau qhov chaw xav tau.
Kev ua tau zoo:
Ob qho khoom siv muaj kev ua tau zoo, tab sis TPUs feem ntau xav tau kev ua haujlwm siab dua.
Tshuaj thiab roj kuj:
TPUs muab cov tshuaj zoo tshaj plaws thiab roj tsis kam piv rau TPEs.
Nqi:
TPEs feem ntau tsis tshua kim, ua rau lawv tsim nyog rau cov ntawv thov raug nqi.
Cov ntsiab lus
TPE thiab TPU txhua tus muaj lawv lub zog, thiab kev xaiv ntawm lawv nyob ntawm cov ntawv thov tshwj xeeb. Piv txwv li, yog tias xav tau kev hnav tsis kam thiab tshuaj lom neeg, TPU yog qhov kev xaiv zoo dua; Yog tias qhov kev xav softer thiab tus nqi qis dua yog qhov tseem ceeb, TPE tej zaum yuav zoo dua. Hauv kev xyaum, cov ntaub ntawv no feem ntau siv ua ke los ua kom zoo dua lawv cov txiaj ntsig.
