Xov Xwm - Xauv Qhov Muaj Peev Xwm ntawm TPEs: Cov Tswv Yim rau Kev Ua Haujlwm Zoo Tshaj Plaws thiab Mar Resistance

Txoj hauv kev los txhim kho Scratch thiab Mar Resistance ntawm TPE cov ntaub ntawv

Thermoplastic elastomers (TPEs) yog cov khoom siv ntau yam uas muab cov yam ntxwv ntawm ob qho tib si thermoplastics thiab elastomers, muab kev yooj yim, ua kom muaj zog, thiab yooj yim ntawm kev ua. TPEs tau dhau los ua qhov kev xaiv zoo tshaj plaws rau cov kws tsim khoom siv thiab cov kws tsim khoom nrhiav cov ntaub ntawv mos, elastomeric. Cov ntaub ntawv no tau siv dav hauv ntau yam lag luam, suav nrog tsheb, khoom siv, khoom siv kho mob, hluav taws xob, HVAC, thiab lwm yam kev siv hauv kev lag luam.

Classifying TPEs

TPEs raug cais los ntawm lawv cov tshuaj muaj pes tsawg leeg: Thermoplastic Olefins (TPE-O), Styrenic compounds (TPE-S), Vulcanizates (TPE-V), Thermoplastic Polyurethanes (TPE-U), Copolyesters (COPE), thiab Copolyamides (COPA). Feem ntau, TPEs zoo li polyurethanes thiab copolyesters dhau-engineered rau lawv daim ntawv thov npaj thaum TPE-S lossis TPE-V yuav yog qhov kev xaiv tsim nyog thiab raug nqi ntau dua.

Cov pa TPEs feem ntau muaj kev sib xyaw ntawm cov roj hmab thiab cov thermoplastic resins. Txawm li cas los xij, thermoplastic vulcanizates (TPE-Vs) txawv vim cov roj hmab hauv cov ntaub ntawv no yog ib feem lossis tag nrho sib txuas los txhim kho kev ua haujlwm.

TPE-Vs muab cov txheej txheem qis dua, cov tshuaj zoo dua qub thiab ua kom tsis zoo, thiab kev ua haujlwm zoo dua ntawm qhov kub thiab txias, ua rau lawv cov neeg sib tw zoo tshaj plaws rau kev hloov roj hmab hauv cov ntsaws ruaj ruaj. Cov pa TPEs, ntawm qhov tod tes, muaj ntau dua kev tsim qauv, tso cai rau lawv tuaj yeem tsim kho rau cov kev siv tshwj xeeb, xws li cov khoom siv, khoom siv hluav taws xob, thiab cov khoom siv kho mob. Cov TPEs no feem ntau muaj zog tensile ntau dua, zoo dua elasticity ("snappiness"), superior colorability, thiab muaj nyob rau hauv ib tug ntau yam ntawm hardness theem.

TPEs kuj tuaj yeem tsim los ua raws li cov txheej txheem nruj xws li PC, ABS, HIPS, thiab Nylon, muab cov khoom muag muag pom ntawm cov khoom xws li txhuam hniav, cov cuab yeej siv hluav taws xob, thiab cov khoom ua si.

Kev sib tw nrog TPEs

Txawm hais tias lawv muaj peev xwm ua tau zoo, ib qho ntawm cov teeb meem nrog TPEs yog lawv qhov cuam tshuam rau khawb thiab mar, uas tuaj yeem cuam tshuam ob qho tib si lawv qhov kev zoo nkauj thiab kev ua haujlwm zoo. Txhawm rau daws qhov teeb meem no, cov tuam txhab lag luam tau vam khom rau cov khoom siv tshwj xeeb uas txhim kho qhov khawb thiab tsis kam ntawm TPEs.

Nkag siab txog Scratch thiab Mar Resistance

Ua ntej tshawb nrhiav cov khoom siv tshwj xeeb, nws yog ib qho tseem ceeb kom nkag siab txog cov ntsiab lus ntawm khawb thiab mar resistance:

Scratch Resistance:Qhov no yog hais txog cov khoom muaj peev xwm tiv taus kev puas tsuaj los ntawm cov khoom ntse lossis cov khoom ntxhib uas yuav txiav lossis khawb rau hauv qhov chaw.
Mar Resistance:Mar kuj yog cov khoom muaj peev xwm tiv thaiv me me ntawm qhov chaw puas uas yuav tsis nkag mus tob tab sis tuaj yeem cuam tshuam rau nws cov tsos, xws li scuffs lossis smudges.

Txhim kho cov khoom no hauv TPEs yog qhov tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas cov khoom raug cuam tshuam rau qhov hnav thiab tsim kua muag tsis tu ncua lossis qhov pom ntawm cov khoom kawg yog qhov tseem ceeb.
