Qhov sib txawv ntawm Polyester TPU thiab Polyether TPU
Nws yog dav paub tiasTPUyog hom yas elastic, uas peb tuaj yeem pom lawv txhua qhov chaw. TPU feem ntau tuaj yeem muab faib ua ob hom: Polyester TPU thiab Polyether TPU. Tau kawg, ob hom TPU no muaj qhov sib txawv. Ntawm no peb qhia qee qhov sib txawv ntawm lawv.
1. Mechanical khoom
Hais txog qhov sib txawv ntawm ntu tawv thiab ntu mos, Polyester thiab Polyether kuj muaj qhov sib txawv ntawm cov cuab yeej siv tshuab. Piv nrog Polyether TPU, Polyester ib qho kev ua tau zoo dua ntawm lub zog, roj tsis kam, thermal-oxidative stability.
2. Hydrolytic stability
TPU yog ib qho yooj yim los cuam tshuam los ntawm cov dej molecules kom tau tawg. Tom qab ntawd cov kua qaub los ntawm hydrolyzation ua rau polyester hydrolyze ib zaug ntxiv. Nws paub rau txhua tus uas nyob hauv TPU kev lag luam uas TPU yuav tsum tau qhuav ua ntej ua. Tab sis Polyester muaj kev ruaj ntseg hydrolytic phem dua li Polyether.
3. Microorganism tsis kam
Thaum polyester TPU tau faus los ntawm cov av ntub, nws yuav raug corroded los ntawm cov kab mob. Tab sis nyob rau tib lub sijhawm, polyether TPU qhia cov ntaub ntawv zoo dua.
4. Lub sijhawm txias
Muaj kev sib txhuam loj dua ntawm cov molecules ntawm Polyester TPU, tom qab ntawd nws muaj zog cohesive loj dua, uas ua rau muaj qhov nyuaj ntawm Polyester TPU rau tub yees. Yog li, piv nrog Polyether TPU, Polyester xav tau sijhawm ntev dua kom txias kom khov tom qab ua tiav.
