Nto xov cov neeg ua hauj lwm siv rau fiberglass ntaub ua ntej PTFE txheej yog ib qho tseem ceeb rau qhov kawg PTFE high-temperature daim ntaub. Organosilane coupling cov neeg ua haujlwm tsim cov txuas txuas ntawm cov iav fiber ntau thiab cov organic PTFE, txhawb nqa lub zog tev ntawm <2 N / cm rau 4-8 + N / cm. Kev kho kom zoo kuj tseem txhim kho cov cua sov (260 ° C +), dielectric kev ua tau zoo, thiab tshuaj tiv thaiv. Cov ntaub tsis kho ua rau delamination, bubbling, thiab lub neej ua haujlwm luv.

Warp thiab weft ceev ntawm fiberglass ntaub txiav txim siab PTFE high-temperature ntaub ua haujlwm. Higher density increases tensile strength and surface smoothness but reduces tear strength (inverted U-curve), flexibility, and coating penetration. Optimal density balances penetration, tear resistance, elasticity, and deg finish. Tsawg ceev haum dynamic dabtsi yog khoov; high density rau non-stick thiab rwb thaiv tsev.

Fiberglass weave qauv - dawb, twill, los yog satin - cuam tshuam rau PTFE siab-kub ntaub ntaub. Satin weave muaj lub zog tsim kua muag siab tshaj plaws (2-3x tiaj) thiab yooj, zoo tagnrho rau dynamic dabtsi yog khoov. Plain weave muab qhov zoo tshaj plaws kev ruaj ntseg thiab tev adhesion, haum rau kev siv zoo li qub. Twill sib npaug tag nrho cov khoom siv rau kev siv dav dav.

Txheej txheej uniformity ntawm PTFE high-temperature npuag yog txiav txim los ntawm plaub yam: txheej formulation (particle loj 0.15-0.35 μm, viscosity, khoom cov ntsiab lus), txheej & sintering txheej txheem (hniav txheej nyiam rau uniformity), substrate zoo (weave qauv, pre-kho), thiab ntau lawm ib puag ncig (<20-25% R,). Dip + hniav ua ke txheej txheem sib npaug nkag mus thiab nto smoothness.

Kev tu thiab tu kom zoo txuas ntxiv lub neej ntawm PTFE high-temperature ntaub. Ntxuav tom qab siv thiab tom qab txias. Siv cov txhuam hniav mos, cov tshuaj ntxuav tes tsis huv, lossis dej cawv rau stains. Tsis txhob siv cov kua qaub/alkalis, tshuaj dawb, lossis hlau scrapers. Tsis tu ncua silicone roj lubrication txo hnav. Ua raws li cov lus qhia no txhawm rau tiv thaiv cov txheej txheem puas tsuaj.
