Ukucutshungulwa kwe-PTFE Nezicelo

Yini?I-PTFE?

Ake siqale ukuhlola kwethu ukuthi iyini ngempela i-PTFE.Ukuze uyinike isihloko sayo esigcwele, i-polytetrafluoroethylene i-polymer yokwenziwa ehlanganisa izakhi ezimbili ezilula;ikhabhoni kanye ne-fluorine.Isuselwa ku-tetrafluoroethylene (TFE) futhi inezici ezithile ezihlukile eziyenza ibe yinto ewusizo ezinhlobonhlobo zezinhlelo zokusebenza.Ngokwesibonelo:

Iphoyinti lokuncibilika eliphezulu kakhulu: Ngephuzu lokuncibilika elingama-327°C, kunezimo ezimbalwa kakhulu lapho i-PTFE ingalinyazwa ukushisa.

I-Hydrophobic: Ukumelana namanzi kusho ukuthi awalokothi abe manzi, okwenza abe wusizo ekuphekeni, ekubopheni amanxeba nokunye.

Inert ngamakhemikhali: Iningi lezincibilikisi namakhemikhali ngeke kulimaze i-PTFE.

I-coefficient ephansi yokungqubuzana: I-coefficient of friction ye-PTFE ingenye yezinto eziphansi kakhulu kunoma yikuphi okuqinile okukhona, okusho ukuthi akukho okuzonamathela kukho.

Amandla aphezulu okugoba: Ikhono lokugoba nokugoba, ngisho nasezingeni eliphansi lokushisa, kusho ukuthi lingasetshenziswa kalula ezindaweni ezihlukahlukene ngaphandle kokulahlekelwa ubuqotho bawo.

Ukucutshungulwa kwe-PTFE

I-PTFE ingatholakala kumafomu e-granular, ukuhlakazeka kanye nempushana ecolekileyo.I-Semi-crystalline PTFE inezinga lokushisa eliphezulu elincibilikayo kanye ne-viscosity encibilikayo, okwenza i-extrusion evamile kanye nokubumba komjovo kube nzima.Ukucubungula kwe-PTFE, ngakho-ke, kufana kakhulu nokucutshungulwa kwempushana kunaleyo yamapulasitiki endabuko.

I-PTFE eyi-Granular ikhiqizwa ngokusabela kokumiswa kwe-polymerisation okusekelwe emanzini.I-resin ewumphumela ye-granular ivame ukucutshungulwa ibe yisimo ngokubunjwa kokucindezelwa.Imikhiqizo yokuhlakazwa ye-PTFE ikhiqizwa ngendlela efanayo, ngama-ejenti angeziwe ahlakazayo.Imikhiqizo yokuhlakazwa ingasetshenziselwa ukumbozwa kwe-PTFE noma ingacutshungulwa ibe yifilimu elincanyana ngokusakazwa kwefilimu.I-PTFE powder ikhiqizwa ngendlela ye-emulsion polymerisation reaction.Impushana ewumphumela ewumphumela inganamathiselwa ikhishwe kumateyipu e-PTFE, amashubhu e-PTFE, nokufakwa kwezintambo, noma isetshenziswe njengesithasiselo sokwandisa ukumelana nokugqwala kwezinye izinto ze-polymeric.

Izicelo Eziphezulu Ezi-5 Ze-PTFE

1. Ukusetshenziswa kwezakhiwo zokulwa nokugqwala

Irabha, ingilazi, ingxubevange yensimbi nezinye izinto ezisetshenziswayo ziyehluleka ukuhlangabezana nezimo ezinzima zamazinga okushisa, ingcindezi kanye nemvelo yokuhlalisana kwemidiya yamakhemikhali ngenxa yamaphutha azo ekumelana nokugqwala.Nokho, PTFE has omuhle kakhulu anti-ukugqwala ukumelana futhi ngaleyo ndlela isibe main materials ukumelana nokugqwala for petroleum, amakhemikhali, yendwangu kanye nezinye izimboni.

2. Ukusetshenziswa kwezakhiwo zokungqubuzana okuphansi emthwalweni

Ukugcotshwa kukawoyela akuzifanele izingxenye zokungqubuzana zezinye izinto zokusebenza, ngoba amafutha okugcoba angancibilika ngezincibilikisi futhi angasebenzi, noma imikhiqizo esezindaweni zemithi, ukudla, izindwangu kanye nezinye izimboni kudingeka igweme ukungcoliswa izinto zokugcoba.Ngenxa yalokho, ipulasitiki ye-PTFE, i-coefficient of friction yayo iphansi kunanoma iyiphi enye impahla eqinile eyaziwayo, isiphenduke into ekahle kakhulu yokugcotshwa kwamafutha angenawo uwoyela (ukuthwala okuqondile) kwezingxenye zemishini.

3. Isicelo kugesi kanye ne-elekthronikhi

Ukulahlekelwa okuphansi okungokwemvelo kanye nokungaguquguquki okuncane kwe-dielectric kwempahla ye-PTFE kuzenza ibe intambo enoqwembe lwamamotho amancane, ama-thermocouples namadivayisi okulawula.Ifilimu ye-PTFE iyinto efanelekile yokwaleka ekukhiqizeni ama-capacitor, ulayini wokufaka umsakazo, izintambo ezingavamisile, izinjini kanye nama-transformer, futhi ingenye yezinto ezibalulekile endaweni yendiza nezinye izinto zikagesi zezimboni.

4. Isicelo kwezokwelapha

I-PTFE Enwetshiwe ayisebenzi futhi iguquguquka kakhulu ngokwebhayoloji, ngakho ayibangeli ukwenqatshwa ngumzimba, ayinayo imiphumela emibi yezokuphila emzimbeni womuntu, ingavalwa inzalo nganoma iyiphi indlela, futhi inesakhiwo esinama-microporous amaningi.

5. Ukusetshenziswa kwezakhiwo zokulwa ne-adhesive

Ngokucindezela okuphansi komhlaba kwanoma iyiphi into eqinile, i-PTFE Teflon ayinamatheli kunoma iyiphi into.Ngaphezu kwalokho, inokumelana okuhle kakhulu namazinga okushisa aphezulu naphansi.Ngenxa yalokho, iye yasetshenziswa kabanzi esicini sokunamathela esiqinile samapani angenanduku.
