Ukwenziwa kwePTFE kunye nezicelo

Yintoni iPTFE?

Masiqale ukuphonononga kwethu ukuba yintoni kanye kanye i-PTFE.Ukunika isihloko sayo esipheleleyo, i-polytetrafluoroethylene yipolymer yokwenziwa equka izinto ezimbini ezilula;ikhabhoni kunye nefluorine.Ithathwe kwi-tetrafluoroethylene (TFE) kwaye ineempawu ezizodwa ezenza kube yinto eluncedo kwizinto ezininzi zokusetyenziswa.Umzekelo:

Indawo yokunyibilika ephezulu kakhulu: Ngendawo yokunyibilika ejikeleze i-327°C, kukho iimeko ezimbalwa kakhulu apho i-PTFE inokonakaliswa bubushushu.

I-Hydrophobic: Ukuxhathisa emanzini kuthetha ukuba akaze abe manzi, oko kuwenza abe luncedo ekuphekeni, ekubopheni amanxeba nokunye.

Inert yekhemikhali: Uninzi lwezinyibilikisi kunye neekhemikhali aziyi konakalisa i-PTFE.

I-coefficient esezantsi yokhuhlane: I-coefficient yokhuhlane lwe-PTFE yenye yezona zinto zisezantsi kuzo naziphi na eziqinileyo ezikhoyo, okuthetha ukuba akukho nto iya kubambelela kuyo.

Amandla aphezulu e-flexural: Iyakwazi ukugoba kunye nokuguquguquka, nakwiqondo lokushisa eliphantsi, lithetha ukuba linokusetyenziswa ngokulula kwiindawo ezahlukeneyo ngaphandle kokulahlekelwa ingqibelelo.

Ukwenziwa kwePTFE

I-PTFE inokufumaneka kwiifom zegranular, ukusabalalisa kunye nomgubo ocolekileyo.I-Semi-crystalline PTFE inobushushu obuphezulu bokunyibilika kunye ne-viscosity enyibilikayo, yenze ukuba ukukhutshwa okuqhelekileyo kunye nokubumba inaliti kube nzima.Ukusetyenzwa kwe-PTFE, ke ngoko, kufana kakhulu nomgubo wokwenziwa komgubo kuneeplastiki zemveli.

I-PTFE yeGranular iveliswa kwi-reactual suspension polymerisation reaction.I-resin ye-granular ephumayo isoloko icutshungulwa ibe yimilo ngokubumba ngoxinzelelo.Iimveliso ze-PTFE zokusasazwa ziveliswa ngendlela efanayo, kunye neearhente zokuchithachitha ezongeziweyo.Iimveliso zokusasazwa zingasetyenziselwa iingubo ze-PTFE okanye zinokusetyenzwa zibe yifilimu ebhityileyo ngokuphosa ifilimu.I-PTFE powder iveliswa kwi-emulsion polymerisation reaction.Isiphumo somgubo ocoliweyo sinokuncamatheliswa kwiteyiphu ze-PTFE, i-PTFE i-tubing, kunye nokugquma ucingo, okanye isetyenziswe njengesongezo sokwandisa ukuxhathisa ukubola kwezinye izinto ze-polymeric.

Izicelo ezi-5 eziphezulu ze-PTFE

1. Ukusetyenziswa kweempawu ezichasene nokubola

Irabha, iglasi, ingxubevange yesinyithi kunye nezinye izinto ziyasilela ukuhlangabezana neemeko ezinzima zobushushu, uxinzelelo kunye neekhemikhali zokuhlalisana kweendaba ngenxa yeziphene zazo ekuxhathiseni ukubola.Nangona kunjalo, i-PTFE inoxhathiso olubalaseleyo lokuchasa umhlwa kwaye ngenxa yoko iye yaba zezona zinto zixhathisayo kwi-petroleum, imichiza, ilaphu kunye namanye amashishini.

2. Ukusetyenziswa kweempawu eziphantsi zokukhuhlana kumthwalo

I-oyile yokuthambisa ayifanelekanga kwiindawo zokukhuhlana zezinye izixhobo, kuba igrisi yokuthambisa inokunyibilika zizinyibilikisi kwaye ayisebenzi, okanye iimveliso ezikwicandelo lamayeza, ukutya, impahla yelaphu kunye namanye amashishini kufuneka ziphephe ukudyojwa zizithambiso.Ngenxa yoko, iplastiki ye-PTFE, i-coefficient of friction isezantsi kunayo nayiphi na enye into eyaziwayo eqinileyo, iye yaba yeyona nto ifanelekileyo yokuthambisa i-oyile (ithwele umthwalo othe ngqo) wezixhobo zemishini.

3. Ukusetyenziswa kombane kunye ne-elektroniki

Ilahleko ephantsi ephantsi kunye ne-dielectric encinci engaguqukiyo ye-PTFE imathiriyeli izenza ukuba yenziwe ibe yintambo ene-enameled yeemoto ezincinci, i-thermocouples kunye nezixhobo zokulawula.Ifilimu ye-PTFE yeyona nto ifanelekileyo yokugquma izixhobo zokwenziwa kwee-capacitors, i-radio insulation liner, iintambo ezigqunyiweyo, iimotor kunye neziguquli, kwaye ikwayenye yezinto eziyimfuneko kwi-aerospace kunye namanye amacandelo e-elektroniki oshishino.

4. Isicelo kwiyeza zonyango

I-PTFE eyandisiweyo ayisebenzi kwaye iguquguquka kakhulu ngokwebhayoloji, ngoko ayibangeli ukwaliwa ngumzimba, ayinaziphumo ebezingalindelekanga zefiziyoloji kumzimba womntu, inokuvalwa inzala ngayo nayiphi na indlela, kwaye inolwakhiwo lwemicroporous emininzi.

5. Ukusetyenziswa kweempawu ezichasene ne-adhesive

Ngoxinzelelo olusezantsi lwazo naziphi na izinto eziqinileyo, i-PTFE Teflon ayibambeleli kuyo nayiphi na into.Ngaphezu koko, inokumelana okugqwesileyo kumaqondo obushushu aphezulu naphantsi.Ngenxa yoko, isetyenziswe ngokubanzi kwi-anti-adhesive feature ye-non-stick pans.
