Qhov zoo ntawm PTFE

PTFE (Polytetrafluoroethyene) yog fluorocarbon polymers. Cov qauv tshuaj ntawm PTFE muaj cov hydrogen atoms ntawm polyethylene kiag li tshem tawm los ntawm fluorine atoms los ua ib tug siab molecule. Qhov no yog tus qauv ruaj khov heev. Yog vim li cas PTFE yog ib tug polymer uas tsis muaj hnub nyoog.

PTFE yog cov khoom siv sealing zoo tshaj. Nws yog huv si thiab tsis lo, koj tuaj yeem siv rau kev lag luam khoom noj. Nws tuaj yeem ua haujlwm txog 260 C. Nws tuaj yeem ua haujlwm ntawm pH 0-14. Nws tuaj yeem ua tiav rau hauv zaj duab xis, thaiv lossis txhua yam duab. Nws muaj cov coefficient tsawg ntawm kev sib txhuam thiab lubrication tsis tas yuav tsum tau ua. PTFE tuaj yeem ua haujlwm ua ke nrog lwm cov ntaub ntawv xws li fiberglass lossis tooj liab kom tau txais cov cuab yeej zoo dua qub.Thaum PTFE nthuav dav kom zoo, cov fiber ntau hloov ntawm cov plaub hau zoo li cov qauv hauv lub vev xaib thiab ua kom muaj zog dua thaum nws sib zog dua.
