Menene microstructural halaye na Teflon high-zazzabi masana'anta?

I. Substrate Skeleton: Glass Fiber Weaving Texture

1. Tsari Tsare-Tsaren Warp-Weft

The Ana saƙa masana'anta daga yadudduka na fiber gilashi masu yawa a fili, twill, ko wasu saƙa don samar da kwarangwal, tare da diamita na monofilament guda ɗaya daga microns da yawa zuwa sama da microns goma, da fili mai santsi.

2. Maɗaukakin Ƙarfi

Kafin shafi, akwai da yawa micron-sikelin pores duka a cikin fiber daure da kuma a warp-weft intersection nodes, samar da sarari ga m PTFE impregnation.

II. Rubutun Halittu: Tsarin 'Tsarin Tsibiri' na PTFE

1. Cikakken Encapsulation

PTFE guduro shiga cikin gibba tsakanin kowane mutum filament, forming a 'reinforced kankare ' -type composite, inda gilashin zaruruwa hidima a matsayin ƙarfafa lokaci da PTFE hidima a matsayin ci gaba da matrix. A cikin ɓangaren giciye, ana iya ganin zaruruwa daidai gwargwado a cikin guduro.

2. Surface Nodular Microstructure

Tsarin PTFE mai tsabta yana nuna nau'i na nau'i na cibiyar sadarwa na nodules (barbashi) da aka haɗa ta hanyar fibrils masu kyau, wanda aka kafa ta hanyar haɗuwa da nau'i-nau'i na lamellae a yayin aikin sintiri, wanda ke ba da kaddarorin da ba na sanda ba da kayan shafawa.

3. Ci gaba da Danse Skin Layer

An wadatar da saman saman tare da PTFE mai tsafta, yana samar da fim mai yawa, fim ɗin fata mara fiber-gilashi da yawa zuwa dubun microns lokacin farin ciki, wanda ke aiki a matsayin babban shinge don rashin kuzarin sinadarai, kaddarorin da ba na sanda ba, da rufin lantarki.

III. Maɓalli Maɓalli: Ƙaƙƙarfan Ƙarƙashin Ƙarƙashin Ƙira da Halayen Mu'amala

1. Residual Micropores

Rashin cikawa ko raguwa a lokacin sintering na iya barin ɓoyayyiyar sikelin micron ko fashe a tsakiyar dauren fiber da kuma ƙuƙumman saƙa, wanda ke haifar da raguwar aikin sakin da juriya na sinadarai.

2. Interface bonding

Gilashin fibers da PTFE ba su dace ba; Ana iya ganin ramukan santsi da aka bari ta hanyar cire fiber. Ta hanyar jiyya ta hanyar haɗin gwiwa ko haɗin kai na inji, PTFE tana ƙarfafa zaruruwa tam, inganta ƙarfin haɗin fuska.

IV. Halayen Jiha Maƙasudi: Tsarin Semi-Crystalline

1. Spherulites da Banded lu'ulu'u

PTFE ne Semi-crystalline polymer. Bayan ɓangarorin al'ada, yana nuna haɗin kai na spherulites da lu'ulu'u masu ɗamara, tare da crystallinity yawanci jere daga 50% zuwa 70%, da tsari mai tsari mai kyau na kwayoyin halitta.

2. Tasirin Crystallinity

Babban crystallinity yana ba da kayan tare da juriya na zafi na dogon lokaci har zuwa 260 ° C da matsanancin matsanancin zafi mai zafi. Ƙarfafawa ko rashin daidaituwa na iya haifar da jahohin crystalline mara kyau, yana rage rayuwar sabis.
