Ntau qhov tshwj xeeb ntawm PTFE board

Lub Rooj Tswjhwm Saib PTFE nws tus kheej tsis muaj kev phom sij phom sij, tab sis ib qho ntawm cov ntaub ntawv raw siv hauv cov txheej txheem tsim khoom tau txiav txim siab kom muaj cov nyhuv carcinogen. Qhov kub yog -20 ~ 250 ° C (-4 ~ +482 ° F), tso cai rau kom txias sai thiab ua kom sov sai, lossis txias thiab cua sov los hloov qhov haujlwm tiag. Ua haujlwm siab-0.1 ~ 6.4Mpa (tag nrho qhov tsis zoo rau 64kgf/cm2) (Fullvacuumto64kgf/cm2) Nws tsim tau daws nrog ntau yam teeb meem hauv Suav teb' tshuaj lom neeg cog, roj av, kev lag luam tshuaj thiab lwm yam lag luam. PTFE hydraulic seals, sealing rings, gaskets., PTFE hydraulic seals, gaskets yog ua los ntawm ntab thiab sib sau ua ke PTFE epoxy roj hmab thiab cov khoom yas. Piv nrog rau lwm cov yas, PTFE muaj cov yam ntxwv ntawm cov kuab tshuaj tiv taus xeb. Nws tau siv dav siv ua roj hmab ntsaws ruaj ruaj thiab cov khoom siv raw. Nws cov tshuaj sib txawv sib txawv ntawm 500 ℃ yog tetrafluoroethylene, hexafluoropropylene thiab octafluorocyclobutane. Cov tshuaj no yuav yaj cov tshuaj fluorine cov ntsiab lus hnyav ua kom tawg thaum nws siab.

Polytetrafluoroethylene phaj tsis nplaum-cov ntaub ntawv raw tsis cuam tshuam rau kev sib zog tsis nplaum txhua yam tshuaj lom neeg lub cev uas qhov kev sib txhuam tsis kam yog qhov tsawg heev, tsuas yog siv lub siab polyethylene ntawm 1/5, nws yog qhov tseem ceeb ntawm perfluorocarbon tsuag txheej txheej. Thiab vim tias kev sib cuam tshuam ntawm cov qauv txheej txheem ntawm cov tshuaj fluorine-carbon qis heev, PTFE tsis khov.

Teflon phaj tsis muaj cov tshuaj phem-nrog rau lub cev yas, raws li cov hlab ntsha dag thiab cov kabmob hauv lub cev tau siv ntev ntev yam tsis muaj kev phiv. Tus txheeb ze dielectric tsis tu ncua thiab dielectric poob ntawm hluav taws xob ua haujlwm PTFE hauv qhov dav dav yog qhov tsawg heev, thiab kev tawg ntawm lub zog, qhov tsis kam tiv thaiv thiab tiv thaiv hluav taws xob ua kom sov ua haujlwm siab dua. Cov yam ntxwv hluav taws xob tiv taus Cov yam ntxwv hluav taws xob tiv taus ntawm PTFE tsis muaj zog, thiab lawv tau yaj los ntawm cov khoom siv hluav taws xob ntau dua. Cov hluav taws xob thiab lub cev ua haujlwm ntawm cov ntaub ntawv polymer raug txo qis.
