High-zoo PTFE coj los tiv thaiv

Kev cai-ua qhov chaw ntawm PTFE ua rau kom cov kev pab cuam lub neej ntawm tus txheej txheem cov khoom (tshwj xeeb tshaj yog raug abrasive xov xwm) nyob rau hauv peb - plaub lub sij hawm.

Nws yog lub npe hu hais tias lub ntsiab kev coj ntawm xeb nyob rau hauv lub tshuaj kev lag luam yog kev tiv thaiv los ntawm cov hlau. Txawm tias tus nruam txhim kho ntawm cov zoo tshaj ntawm yas thiab composites, feem ntau exploited hnub no hauj khoom yog tseem ua los ntawm cov hlau.

PTFE cov khoom muaj lub siab coj kuj. Raws li deb raws li qhov no cov ntaub ntawv uas pab txoj kev zoo ntawm cov chav nyob, kev txhim kho cov ntsiab xws machines li zawv zawg bearings, hnab twb qhib lawm thiab ris peb tau pom txhiab ntawm cov neeg muas zaub "Eco-RTI-tuav". Ntawm lawv, thawj ntawm tag nrho cov tshuaj thiab engineering Enterprises, uas, ua tsaug rau qhov zoo tshaj ntawm PTFE yuav txo tau tus nqi ntawm kev kho ntawm compressors, tshuab cov cuab yeej thiab tag nrho cov hom ntawm kev sib txhuam units.

Nrog kev xav txog cov hardness ntawm cov khoom, qhov no PTFE polymer tshaj txawm siv ua ntej av txau rau lub piston rods. Raws li cov polymerization ntawm tetrafluoroethylene siv fluoroplastic muab exceptional nws Brinell hardness txog li 40 MPa thiab tshuam pes tsawg porosity. Raws li ib tug tshwm sim ntawm ib yam tshuaj txheej txheem, ib cov ntaub ntawv uas ceev ntawm 2200 kg / cm3, uas, nyob rau hauv ib tug PP electron tshuab kuaj kab mob cov qauv muaj ib tug convex nto. Qhov no me ntsis sib npaug nto yog nyob rau hauv stark sib piv nrog ib tug concave, nrog cov npoo ntawm cov qauv, raug rau tsis ruaj tsis khov ntaub ntawv rau koj hnav.

Sau PTFE yog cov ob peb polymers uas yuav tau ua los ntawm lub ntsiab ntawm cov centrifugal twj. Qhov kom zoo dua ntawm lub yav tas piv nrog analogues los ntawm hlau (nrog rau cov txojkev insulated txheej) yog tshem tawm qhov sib txawv ntawm thermal expansion ntau ntawm cov hauv ob sab phlu thiab cov hlau. Distributors, redistributors thiab sealing - lub puab valve - kuj tiv thaiv thov fluoropolymer tebchaw.

Ntim nqaws, daim kab xev FUM thiab teeb meem-dawb lub lag luam.

Vim hais tias PTFE preforms manufactured membrane, gaskets thiab O-rings, uas lub lag luam tsis tau yuav tsum tau tiv thaiv txij nkawm thiab thaum muaj xwm ceev. Zoo tshaj plaws yog tsis tau tsuas yog mus cuag ib tug siab Brinell hardness ntawm 20-25 units ntau dua li cov hardness ntawm lwm yam ntaub ntawv muaj nyob rau ntawm lub lag luam. Nrog rau xoom dej haum PTFE pas nrig los yog phaj ua si ib tug tseem ceeb luag hauj lwm nyob rau hauv txo lub abrading muaj peev xwm nyob rau hauv kev sib raug zoo mus rau lub counter tsiv chaw.

Rau hauv sib piv, ntau yam composites ntawm lub concave microstructure, rings thiab bushings ntawm polytetrafluorethylene tsis deteriorate los ntawm spalling tshaj yog ruaj khov yam tsawg kawg nkaus kev sib txhuam. Nyob rau hauv tas li ntawd lub dag lub zog thiab kev cia siab ntawm tej yam cov pob qij txha, qhov khoob thiab overlapping fasteners yuav tsuas yog muab ib daim kab xev FUM tsim los ntawm cov PTFE cab rau kev sib khi ntawm lub hydraulic sib txuas. Tsis tas li ntawd band FUM muas yuav los tiv thaiv cov mounting qhov tsawg vapor diffusion thiab roj.
