Ingcaciso kunye neSakhiwo

Iitywina ze-oyile ze-PTFE zizigasthi ezinomatshini eziyilelwe ukugcina izithambisi kwaye zingaquki izinto ezingcolisayo kwishafu ezijikelezayo okanye ezibuyiselanayo. Ulwakhiwo lwabo lubandakanya:

• Imilebe ye-PTFE: I-low-friction edge yokutywina ehambelana nokungafezeki kwe-shaft.

• Isilayishi saseNtwasahlobo (Ngokhetho): Yandisa amandla eradial kwizicelo zoxinzelelo oluphezulu.

• Metal Case: Insimbi engenasici okanye i-carbon steel yendlu yokunyaniseka kwesakhiwo.

• Izangqa ze-Anti-Extrusion: Thintela deformation phantsi koxinzelelo olukhulu.

Ulwakhiwo lwemolekyuli ye-PTFE-umqolo wekhabhoni ozaliswe ngokupheleleyo ziiathom zefluorine-ibonelela ngokungena ngaphakathi kuzo zonke iikhemikhali, kubandakanya iiasidi, izinyibilikisi, kunye namafutha. Umphezulu wayo ogudileyo unciphisa ukunxiba kunye nokulahleka kwamandla, oko kuyenza ilungele ukutywinwa okuguquguqukayo.

## PTFE vs. Nitrile kunye neFKM Oyile Izitywina: Umahluko ongundoqo

Kutheni i-PTFE Iphumelela Kwimekobume Eburhabaxa:

• Dry Ukubaleka Ukukwazi: Iipropati zokuzithambisa ze-PTFE ziphelisa imfuneko yegrisi zangaphandle kwiimeko ezininzi, ukunciphisa iingozi zosulelo.

• Zero ukuDumba: Ngokungafaniyo ne-elastomers, i-PTFE iyaxhathisa ukudumba kulwelo olusekwe kwi-hydrocarbon.

• Ukuthotyelwa kwe-FDA: I-PTFE ivunyiwe kwizicelo zokutya kunye namayeza.

## Usetyenziso kunye neMigaqo yokuSebenza

Zisetyenziswa phi izitywina zeoyile ye-PTFE?

1. Iimoto: Iishafu zeTurbocharger, iinkqubo zothumelo, kunye neenkqubo zokupholisa ibhetri ye-EV.

Zisebenza Njani Iitywina zePTFE?

Amatywina e-PTFE asebenza ngale:

• Ukutywinwa okuguquguqukayo: Umlebe we-PTFE uhambelana nokungahambi kakuhle kweshaft okanye izitenxo zomphezulu.

• IsiZukulwana sobushushu esincinci: Ukungqubuzana okuphantsi kunciphisa ukuthotywa kwe-thermal.

• Ukutywinwa okungaguquguqukiyo kunye nokuGuqulelayo: Isebenza kuzo zombini izicelo ezimileyo kunye nesantya esiphezulu (ukuya kwi-25 m / s).

## Isikhokelo sokuthanjiswa: Ngaba amatywina ePTFE afuna iGrisi?

I-PTFE's lubricity yendalo ihlala isusa imfuno yezithambiso zangaphandle. Nangona kunjalo, kwiimeko ezinomthwalo omkhulu okanye ezinesantya esiphezulu,iigrisi ezisekelwe kwi-siliconeokanyePFPE (perfluoropolyether) iolizinconywa ngenxa yokuhambelana kwazo kunye nokuzinza kwe-thermal. Ziphephe iigrisi ezisekelwe kwi-petroleum, ezinokuthoba i-PTFE ekuhambeni kwexesha.

## Ukufumana njani ukuvuza kweOyile yeSitywina

1. UHlolo Olubonwayo: Jonga intsalela yeoli ejikeleze indlu yetywina.

2. Uvavanyo loxinzelelo: Faka uxinzelelo lomoya ukujonga amaqamza aqhweshayo.

3. Iimetriki zokuSebenza: Lawula i-spikes yobushushu okanye ukonyuka kokusetyenziswa kwamandla, ebonisa ukukhuhlana ukusuka kwitywina elingasebenziyo.

## I-Oli ye-Oli yeSitywini soBomi bexesha loBomi: Izinto kunye nokulindelweyo

PTFE ioli amatywina kwiinjini zihlala zihlala8-12 iminyaka, kuxhomekeka kwi:
