Ndeapi ma microstructural maitiro eTeflon yakakwirira-tembiricha jira?

I. Substrate Skeleton: Girazi Fiber Weaving Texture

1. Warp-Weft Interwoven Structure

The jira rakarukwa kubva kune akawanda-strand girazi faibha yarns mubani, twill, kana mamwe machira kuti aite mesh skeleton, ine ega monofilament diameters kubva kune akati wandei mamicrons kusvika kune gumi mamicrons, uye yakatsetseka pamusoro.

2. High Porosity

Asati apfekedzwa, kune akawanda ma micron-scale pores ese ari mukati mefiber bundles uye pawarp-weft intersection node, zvichipa nzvimbo yeinotevera PTFE impregnation.

II. Coating Morphology: Iyo 'Island-Coating' Mamiriro ePTFE

1. Yakazara Impregnation Encapsulation

PTFE resin inopinda mumikaha pakati pega yega filament, ichigadzira ' reinforced concrete ' -type composite, apo magirazi egirazi anoshanda sechikamu chekusimbisa uye PTFE inoshanda sematrix inoenderera mberi. Muchikamu-chikamu, mafiber anogona kuonekwa akabatanidzwa mukati me resin.

2. Surface Nodular Microstructure

Iyo yakachena PTFE pamusoro inoratidza yakasarudzika network morphology yemanodule (particles) akabatana neakanaka fibrils, akaumbwa nekuunganidzwa kweakapetwa-ketani lamellae panguva yekuita sintering, iyo inopa isiri-tsvimbo uye yekuzvizora zvinhu kune iyo chinhu.

3. Inoenderera Dense Skin Layer

Iro repamusoro rakagadzirwa nePTFE yakachena, ichiita ganda rakakora, girazi-fiber-isina firimu reganda rakati wandei kusvika kumakumi emamicrons gobvu, rinoshanda sechidziviso chakakosha chemakemikari inertness, isina-tsvimbo, uye magetsi ekudzivirira.

III. Chikanganiso Chinokosha: Microporosity uye Interface Characteristics

1. Residual Micropores

Kusakwana pamuviri kana shrinkage panguva sintering kunogona kusiya micron-scale voids kana makatsemuka pakati faibha bundles uye panguva interweaving nodes, zvichiita kuti kuderedzwa kusunungurwa kushanda uye makemikari kuramba.

2. Interface Bonding

Girazi fibers uye PTFE hazvienderani; microscopically, makomba akatsetseka akasiiwa nefiber kudhonza-kunze anogona kucherechedzwa. Kuburikidza nekubatanidza kurapwa kwemumiriri kana mekiniki kuvharirana, PTFE inosunga zvakasimba mafiber, ichivandudza interfacial bond simba.

IV. Condensed State Characteristics: Semi-Crystalline Structure

1. Spherulites uye Banded Crystals

PTFE ndeye semi-crystalline polymer. Mushure mekuita sintering yakajairika, inoratidza kugarisana kwema spherulites uye mabhendi makristasi, ane crystallinity inowanzobva pa50% kusvika 70%, uye yakanyatso kurongeka mamorekuru cheni.

2. Mhedzisiro yeCrystallinity

Yakakwirira crystallinity inopa zvinhu nekureba kwekupisa kupisa kusvika ku260 ° C uye yakanyanya kuderera-yepamusoro-tembiricha inokambaira. Kuwedzeredza-kunyungudika kana kudonhedza pasi kunogona kutungamira kune isina kujairika crystalline nyika, kupfupisa hupenyu hwesevhisi.

Mashoko ari pamusoro apa anopiwa ne Jiangsu Aokai New Material Technology Co., Ltd.

Kana iwe uchida kudzidza zvakawanda pamusoro pezvakatsanangurwa, mamiriro ekushandisa, uye zvigadziriso zvegadziriso zvemhando yedu yakazara yezvigadzirwa, zvinosanganisira Teflon yakakwirira-tembiricha jira, Teflon yakakwirira-tembiricha tepi, Teflon yakakwirira-tembiricha mesh mabhandi, seamless conveyor mabhandi emichina yekubatanidza, single-side PTFE-inodzivirira jira rekudzivirira, high-temperature inodzivirira fiberglass jira, ndapota inzwa wakasununguka kutibata nesu kuburikidza neinotevera:

Isu tinogara tichinamatira kune inyanzvi uye yakavimbika sevhisi uzivi, uye takazvipira nemoyo wese kukupa iwe-yekumira mhinduro uye inoteerera sevhisi!
