Ziziphi iimpawu ze-microstructural zeTeflon high-temperature fabric?

I. Substrate Skeleton: Glass Fiber Weaving Texture

1. I-Warp-Weft Interwoven Structure

I Ilaphu lilukwe ukusuka kwimisonto yeglasi enemisonto emininzi elukiweyo ethafeni, kwitwill, okanye kwezinye izinto ezilukiweyo ukwenza i-mesh skeleton, enobubanzi obubodwa be-monofilament ukusuka kwii-microns ezininzi ukuya ngaphezulu kwe-microns ezilishumi, kunye nomphezulu ogudileyo.

2. I-Porosity ephezulu

Phambi kokugquma, kukho iipores ezininzi ze-micron-scale zombini ngaphakathi kwi-fiber bundles nakwi-warp-weft intersection nodes, ezibonelela ngesithuba sokufakwa okulandelayo kwe-PTFE.

II. I-Coating Morphology: 'I-Island-Coating' yoLwakhiwo lwe-PTFE

1. I-Inpregnation Encapsulation epheleleyo

I-resin ye-PTFE ingena kwizithuba phakathi kwe-filament nganye, yenze 'ikhonkrithi eyomeleziweyo'-uhlobo oludityanisiweyo, apho iintsinga zeglasi zisebenza njengenqanaba lokuqinisa kwaye i-PTFE isebenza njenge-matrix eqhubekayo. Kwi-cross-section, ii-fibers zingabonwa ngokulinganayo kwi-resin.

2. Surface Nodular Microstructure

Umphezulu we-PTFE ococekileyo ubonisa i-morphology yothungelwano olwahlukileyo lwamaqhuqhuva (amasuntswana) adityaniswe ziifibrils ezintle, ezenziwe ngokudityaniswa kwe-lamellae esongiweyo ngexesha lenkqubo ye-sintering, enika iipropathi ezingeyontonga kunye ne-self-lubricating kwizinto eziphathekayo.

3. Ucweyo lwesikhumba oluxineneyo oluqhubekayo

Umaleko womphezulu utyetyiswe nge-PTFE esulungekileyo, yenza ifilimu yesikhumba eshinyeneyo, engenaglasi-fiber-free eziliqela ukuya kumashumi eemicrons ezityebileyo, esebenza njengomqobo ongundoqo wokungangeni kweekhemikhali, iipropati ezingabambekiyo, kunye nokugqunyelelwa kombane.

III. Iziphene eziphambili: I-Microporosity kunye ne-Interface Characters

1. IiMicropores ezishiyekileyo

Ukukhulelwa okungaphelelanga okanye ukucutha ngexesha lokutshiza kunokushiya i-micron-scale voids okanye ii-cracks embindini we-fiber bundles kunye ne-interweaving nodes, okukhokelela ekunciphiseni ukukhutshwa kokusebenza kunye nokuxhathisa imichiza.

2. I-Interface Bonding

Iifiber zeglasi kunye ne-PTFE azihambelani; nge-microscopically, imingxuma egudileyo eshiywe kukutsalwa kwefayibha ngaphandle inokubonwa. Ngokudityaniswa kwe-arhente yonyango okanye ukudityaniswa komatshini, i-PTFE ibambelela ngokuqinileyo kwimicu, iphucula amandla ebhondi yangaphakathi.

IV. IiMpawu zoMbuso eziNxinyiweyo: iSemi-Crystalline Structure

1. Spherulites kunye neBanded Crystals

I-PTFE yi-semi-crystalline polymer. Emva kwe-sintering eqhelekileyo, ibonisa ukuhlalisana kwee-spherulites kunye neekristale ezidibeneyo, kunye ne-crystallinity ngokuqhelekileyo ukusuka kwi-50% ukuya kwi-70%, kunye nokuhlelwa kakuhle kwe-molecular chain chain.

2. Impembelelo yeCrystallinity

I-crystallinity ephezulu inika imathiriyeli ukuchasana nobushushu bexesha elide ukuya kuthi ga kwi-260 ° C kunye nokunyuka okuphantsi kakhulu kobushushu obuphezulu. I-over-sintering okanye ngaphantsi-sintering kunokukhokelela kwi-crystalline state engaqhelekanga, ukunciphisa ubomi benkonzo.
