Teflon high-temperature fabric hian eng microstructural characteristics nge a neih?

I. Substrate Skeleton: Glass Fiber hmanga siam dan

1. Warp-Weft hmanga inzawmkhawm (Interwoven Structure) a ni

Chumi puan chu multi-strand glass fiber yarn atanga plain, twill emaw, weave dang emawa siam a ni a, mesh skeleton siam a ni a, monofilament pakhat zel diameter chu micron engemaw zat atanga micron sawm aia tam a ni a, a chunglam chu a hrual a ni.

2. Porosity sang tak a awm

Coating hma hian fiber bundle chhungah leh warp-weft intersection node-ah te micron-scale pores tam tak a awm a, chu chuan a hnu lama PTFE impregnation neih theihna tur hmun a siamsak a ni.

II. Coating Morphology: PTFE siam dan 'Island-Coating' tih hi a ni

1. Impregnation Encapsulation kimchang tak siam a ni

PTFE resin hian filament pakhat zel inkar gap-ah a lut a, 'reinforced concrete'-type composite a siam a, chutah chuan glass fibers te chu reinforcing phase atan an thawk a, PTFE chu continuous matrix atan an thawk bawk. Cross-section-ah chuan fibers te chu resin chhungah inang tlang taka inkhung hran hmuh tur a awm.

2. Lei chunglam Nodular Microstructure hmanga siam a ni

PTFE surface thianghlim hian fibril tha tak tak hmanga inzawmkhawm nodules (particles) network morphology danglam tak a lantir a, sintering process chhunga folded-chain lamellae aggregation atanga siam a ni a, chu chuan material chu non-stick leh self-lubricating property a pe a ni.

3. Dense Skin Layer chhunzawm zel

Surface layer chu PTFE thianghlim hmanga tihhausak a ni a, dense, glass-fiber-free skin film micron engemaw zat atanga sawm vel zeta thuk a siam a, hei hi chemical inertness, non-stick property, leh electrical insulation atana key barrier atan a tangkai hle.

III. Thil chhiatna pawimawh tak tak: Microporosity leh Interface ziarang

1. Micropores awmsa (Residual Micropores) te

Sintering laiin impregnation tling lo emaw, shrinkage emaw chuan fiber bundles lai takah leh interweaving node-ah micron-scale voids emaw crack emaw a awm thei a, hei hian release performance leh chemical resistance a tihhniam phah thei a ni.

2. Interface Bonding tih a ni

Glass fiber leh PTFE hi a inmil lo a; microscopic-ah chuan fiber pull-out-in a hnutchhiah khur hrual (smooth pits) te chu hmuh theih a ni. Coupling agent treatment emaw mechanical interlocking hmangin PTFE hian fibers te chu nghet takin a anchor a, interfacial bond strength a ti tha zawk a ni.

IV. Condensed State ziarang: Semi-Crystalline Structure a ni

1. Spherulite leh Banded Crystal te a awm

PTFE hi semi-crystalline polymer a ni a. Normal sintering hnuah spherulites leh banded crystals te awmna a lantir a, crystallinity chu a tlangpuiin 50% atanga 70% inkar a ni a, molecular chain arrangement pawh a inrual tha hle bawk.

2. Crystallinity-in nghawng a neih dan

Crystallinity sang tak hian material hi 260°C thlenga hun rei tak chhunga lumna do theihna leh high-temperature creep hniam tak tak a pe a ni. Over-sintering emaw under-sintering emaw hian crystalline state pangngai lo a thlen thei a, service life a ti tawi thei bawk.
