Thermal Expansion Coefficient ntawm PTFE High Temperature Fabric

Jiangsu Aokai Cov Khoom Tshiab, cov chaw tsim khoom ntawm PTFE cov ntaub ntawv kub kub, coj koj cov kev paub zoo li hauv qab no:

Lub thermal expansion coefficient ntawm PTFE siab kub ntaub tsis yog tus nqi ruaj. Nws tseem qis qis ntawm chav tsev kub txog 100 ° C (kwv yees li 0.5 × 10⁻⁵ / ° C), tab sis nce siab hauv qhov kub thiab txias.

1. Siv cov ntaub ntawv Thermal Expansion Coefficient ntawm Pure PTFE

Cov lus hauv qab no teev cov thermal expansion coefficients ntawm ntshiab PTFE nyob rau hauv txawv kev xeem, chav tsev: × 10⁻⁵ / ° C. Nco ntsoov tias PTFE cov ntaub kub kub yog cov khoom siv sib xyaw, thiab nws cov khoom siv tag nrho muaj feem xyuam nrog cov iav fiber ntau substrate. Cov ntaub ntawv hauv qab no feem ntau cuam tshuam cov yam ntxwv ntawm cov ntshiab PTFE txheej.

 

Cov ntaub ntawv piav qhia : PTFE qhia me ntsis anisotropy hauv thermal expansion. Cov nqi sib txawv me ntsis los ntawm cov khoom siv qib thiab cov qauv xeem.

2. Cov Ntsiab Cai Ua Haujlwm & Kev Ua Haujlwm Tseem Ceeb

●  Tsawg thermal deformation txoj cai : Qhov kev nthuav dav tsis tshua muaj kev sib koom ua ke los ntawm cov txheej PTFE txheej thiab sab hauv lub zog muaj zog iav fiber ntau daim ntaub. Cov iav fiber ntau muaj qhov sib txawv ntawm cov thermal expansion coefficient ntawm 0.5 × 10⁻⁵ / ° C, uas ua rau muaj txiaj ntsig zoo rau tag nrho cov thermal expansion thiab contraction.

●  Cov nyhuv tsis-linear kub : Qhov hloov pauv ntawm PTFE nce pom tseeb nrog qhov kub thiab txias. Piv txwv li, 1-meter ntshiab PTFE yuav nthuav dav los ntawm 1.2 hli thaum rhuab los ntawm 20 ° C mus rau 120 ° C, thiab qhov nthuav dav tuaj yeem ncav cuag 6.5 hli thaum rhuab mus txog 320 ° C. Tsis tas li ntawd, PTFE muaj qhov hloov pauv ntawm 23 ° C, qhov twg nws qhov kev hloov pauv hloov pauv sai sai, uas xav tau kev saib xyuas tshwj xeeb hauv cov ntawv thov kev lag luam.

●   Kev tsim cov txheej txheem yuav tsum tau ua : Cov cua sov qeeb thiab tsis sib xws yog qhov yuav tsum tau ua thaum lub sijhawm tsim khoom kom sib npaug ntawm qhov sib txawv ntawm cov thermal expansion loj ntawm PTFE txheej thiab iav fiber ntau hauv qab ntaub, zam cov txheej txheej tawg thiab bubbling los ntawm kev ntxhov siab sab hauv.

Nyob rau hauv xaus, tsis tshua muaj thermal expansion yog ib tug tseem ceeb kom zoo dua ntawm PTFE siab kub ntaub, thaum nws lub peev xwm nthuav tiag tiag nce tsis-linearly nrog kub. Cov ntaub ntawv sib thooj coefficient yuav tsum tau muab coj los siv rau kev xam raws li qhov ua haujlwm ntawm qhov kub thiab txias nyob rau hauv high-temperature daim ntawv thov tsim.
