Hla-sectional Structure ntawm PTFE High-Temperature Cloth: Puas Muaj Kev Hloov Pauv Ntawm PTFE Txheej thiab Fiberglass Substrate?

Jiangsu Aokai Cov Khoom Tshiab, cov chaw tsim khoom ntawm PTFE cov ntaub ntawv kub kub, coj koj qhov kev nkag siab tob. Raws li cov khoom siv sib xyaw ua tau zoo, cov qauv siv hluav taws xob sib txuas ntawm PTFE cov ntaub ntawv kub kub yog qhov tseem ceeb rau nws qhov kub thiab txias, tev lub zog thiab yoog raws. Nyob rau hauv cov txheej txheem ntau lawm ntawm PTFE high-temperature ntaub, muaj nyob rau hauv  ib qho tseem ceeb hloov txheej ntawm PTFE txheej thiab fiberglass substrate. Yog tias tsis muaj txheej txheem hloov pauv no, kev sib koom ua ke ntawm cov txheej txheem ntawm PTFE cov ntaub kub kub tsis tuaj yeem ua tiav.

Los ntawm kev txheeb xyuas cov kab mob sib kis, cov txheej txheem kev hloov pauv no tsis yog tsim los ntawm ib qho tshuaj lom neeg, tab sis thaj chaw sib xyaw ua ke tsim los ntawm ntau txoj kev hloov kho lub cev thiab tshuaj. Cov txheej txheem tsim thiab muaj pes tsawg leeg ntawm cov txheej txheem hloov pauv tau piav qhia raws li hauv qab no:

1. Silane Coupling Agent Bonding Txheej

Tsis kho fiberglass tsis tuaj yeem txuas ncaj qha nrog PTFE cob. Yog li ntawd, fiberglass ntaub yuav tsum tau hloov nrog silane coupling agents nyob rau hauv ntau lawm. Ib qho kawg ntawm tus neeg sawv cev sib txuas ua rau muaj kev cuam tshuam nrog cov pab pawg silanol (Si-OH) ntawm cov fiberglass nto, thaum lwm qhov kawg muaj cov pab pawg muaj kev sib raug zoo siab lossis muaj kev cuam tshuam rau fluororesins. Ua hauj lwm raws li ib tug chemical bonding choj ntawm lub fiberglass skeleton thiab PTFE txheej, txheej no muab cov tshuaj anchorage tseem ceeb rau tag nrho cov txheej txheem lamination.

2. Kub-Melt Adhesive Intermediate Txheej

Hauv kev soj ntsuam ntu ntawm PTFE qib high-temperature ntaub, gradient hloov txheej txheej uas muaj PFA (Perfluoroalkoxy alkane) lossis FEP (Fluorinated Ethylene Propylene) tuaj yeem pom meej ntawm PTFE txheej thiab fiberglass substrate. Thaum lub sij hawm kub-kub sintering, cov fluoroplastics meltable no ua raws li cov nplaum kub-kua nplaum, nkag mus thiab qhwv cov fiberglass bundles los tsim ib ntu txuas ntxiv. Cov txheej nruab nrab no tiv thaiv txheej txheej delamination nyob rau hauv rov khoov thiab flexing tej yam kev mob.

3. Mechanical Interlocking Interface

PTFE high-temperature ntaub yog tsim los ntawm ntau yam impregnation thiab txheej txheej txheem. Microscopically, PTFE emulsion nkag mus rau hauv micron qhov pores tsim los ntawm warp thiab weft weaving ntawm fiberglass fabrics. Tom qab sintering thiab kho, lub solidified PTFE resin tsim ib tug peb-seem txheej txheem anchoring qauv nrog cov ntaub fiber ntau. Cov qauv kev sib cuam tshuam lub cev no muab kev txhawb nqa kev siv tshuab txhim khu kev qha, ua kom muaj kev ruaj ntseg ntawm qhov ntev thiab kev ua haujlwm tiv thaiv delamination hauv kev pabcuam ntev.

4. Gradient Buffer Interface

PTFE txheej thiab fiberglass feature sib txawv coefficients ntawm thermal expansion, uas yooj yim induces nyob rau hauv kev nyuaj siab nyob rau hauv ceev cua kub thiab txias mus. Hwm PTFE cov ntaub ntawv kub-kub siv cov txheej txheem gradient: thaj tsam ze rau fiberglass yog nplua nuj nyob rau hauv cov nplaum tiv thaiv tshav kub thiab FEP, thaum PTFE purity maj mam nce mus rau sab nrauv. Cov qauv gradient no buffers thermal stress nyob rau hauv high-temperature tej yam kev mob thiab tsis txhob nto cracking ntawm txheej.

5. Substrate Pretreatment Interface

Ua ntej tsim cov txheej txheem kev hloov pauv saum toj no, fiberglass ntaub yuav tsum tau ua kom kub-kub dewaxing thiab desizing kom tshem tawm textile sizing agents thiab impurities. Cov txheej txheem pretreatment no nthuav tawm cov active silanol pab pawg ntawm cov fiber ntau, muab cov kev sib txuas huv thiab tshuaj lom neeg rau kev sib txuas tom ntej thiab kev nkag mus rau cov resin.

Tus ntoo khaub lig-sectional qauv ntawm PTFE high-temperature daim ntaub tsim ib tug ua tiav cov txheej txheem featured los ntawm kev sib txuas lus muaj zog, gradient nkag mus thiab ntshiab resin ua hauj lwm nto . Tau txais txiaj ntsig los ntawm ntau qhov kev hloov pauv txheej ua ke los ntawm lub cev occlusion thiab tshuaj sib txuas, cov khoom khaws cia cov cuab yeej tso tawm zoo heev thiab kev tiv thaiv corrosion ntawm PTFE, thaum tau txais lub zog tensile zoo thiab qaug zog.
