TPEE yog cov lus teb rau kev hloov PFAS

Lub Koom Haum Tshuaj Lom Neeg European ("ECHA") tau tshaj tawm cov ntaub ntawv qhia txog kev txwv tsis pub siv li ntawm 10,000 yam khoom per- thiab polyfluoroalkyl ("PFAS"). PFAS siv rau hauv ntau yam lag luam thiab muaj nyob rau hauv ntau yam khoom siv. Daim ntawv thov txwv tsis pub siv lub hom phiaj yog txwv tsis pub tsim khoom, muab tso rau hauv kev ua lag luam thiab siv cov tshuaj uas ua rau tib neeg noj qab haus huv thiab ib puag ncig puas tsuaj, thiab txwv tsis pub lawv muaj kev pheej hmoo.

Hauv peb txoj kev lag luam, PFAS siv ua cov khoom rwb thaiv tsev sab nraud ntawm LItz hlau, cov ntaub ntawv tseem ceeb yog Polytetrafluoroethylene (PTFE), ethylene-tetrafluoroethylene (ETFE), tshwj xeeb ETFE yog cov khoom siv zoo tshaj plaws kom tiv taus UV, ozone, roj, kua qaub, cov hauv paus thiab dej tsis nkag.

Raws li txoj cai lij choj European yuav txwv tsis pub muaj PFAS, cov khoom siv no yuav dhau los ua keeb kwm sai sai no, txhua tus kws tshaj lij hauv kev lag luam tau nrhiav cov ntaub ntawv txhim khu kev qha, hmoov zoo peb tau paub los ntawm peb tus neeg muab khoom siv tias TPEE yog qhov yog.
TPEE Thermoplastic Polyester Elastomer, yog kev ua haujlwm siab, cov khoom siv kub siab uas muaj ntau yam ntxwv ntawm thermoset roj hmab thiab lub zog ntawm cov yas engineering.

Nws yog ib qho block copolymer uas muaj ib feem tawv ntawm polyester thiab ib feem mos ntawm polyether. Qhov seem tawv muaj cov khoom ua haujlwm zoo li yas thaum qhov seem mos muab nws nrog kev ywj pheej. Nws muaj ntau yam zoo heev thiab feem ntau siv rau hauv cov khoom siv hluav taws xob, IT, thiab kev lag luam tsheb.

Cov chav kawm thermal ntawm cov ntaub ntawv: -100 ℃ ～ + 180 ℃, qhov nyuaj ntau yam: 26 ～ 75D,

Cov yam ntxwv tseem ceeb ntawm TPEE yog

Kev ua haujlwm qaug zog zoo heev
Kev ua siab ntev zoo
Kev tiv thaiv cua sov siab tshaj plaws
Ruaj khov, hnav tsis kam
Lub zog tensile zoo
Tiv taus roj/tshuaj lom neeg
Kev cuam tshuam siab
Cov khoom siv kho tshuab zoo

Peb yuav sim qhia ntau yam khoom siv kom txaus siab rau koj qhov kev xav tau. Thiab kuj txais tos kom qhia peb cov ntaub ntawv tsim nyog dua.
