PTFE Yashizweho O-Impeta Porogaramu
Aegis, Aflas, Butyl, Fluorosilicone, Hypalon cyangwa ibice byose porogaramu yawe yihariye irashobora gusaba.Gipfundikirwa hamwe na O-Impeta nubundi buryo nabwo:
- Gipfundikirwa cyangwa Gufunga - O-Impeta zometseho PTFE, hamwe na cohasi ifatanye na O-Impeta (ubusanzwe Silicone cyangwa Viton cyangwa NBR).Encapsulated O-Impeta ni O-Impeta (ubusanzwe Silicone cyangwa Viton) itwikiriwe numuyoboro wa PTFE.PTFE itwikiriye O-Impeta nicyiza cyo guteranya hasi aho guhuza ibikorwa ari ikintu cyingenzi.Gufunga O-Impeta yitwara nk'amazi menshi yo mu bwoko bwa viscous fluid, igitutu icyo aricyo cyose kuri kashe cyanduzwa muburyo bwose.Co-O-Impeta iraboneka muburyo bwagutse bwamabara.
- Ibikoresho bidasanzwe - Niba ufite icyifuzo cyurwego rwihariye rutari urwego rusanzwe rwinganda, turashobora gukorana nababikora kugirango tubyare uruganda rwihariye kugirango uhuze ibyo ukeneye.
- Mil-Spec, Mil-Std cyangwa Milspecs ni igipimo cya defese yo muri Amerika ikoreshwa mu kugera ku ntego zisanzwe na Minisiteri y’ingabo z’Amerika.Ikirangantego cya roketi gishobora gutanga Mil-Spec yose binyuze murusobe runini rwabatanga ibyamamare.
- Ibikoresho byo mu rwego rwa FDA, amazina y’amahanga, USP, KTW, DVGW, BAM, WRAS (WRC), NSF, Laboratoire za Underwriters (UL), Aerospace (AMS) na Mil-Spec - Roketi ifite uburambe mu guhuza ibyo ukeneye mu nganda zose.
urashobora guhitamo gukurikira ibara cyangwa andi mabara.
Uzwi cyane ku izina rya Teflon, polytetrafluoroethylene (PTFE) itanga ubuso butagaragara kubikoresho byo guteka, imisumari yimisumari, ibikoresho byo gutunganya imisatsi, kuvura imyenda / itapi, hamwe nicyuma cyogeza ikirahure.Nyamara, ababikora barabona inyungu ziyongera mugukoresha PTFE nkuburyo bwo gukora O-impeta nziza.O-impetayubatswe ukoresheje PTFE itanga ubushyuhe bwumuriro nubumara, kandi birashobora kurwanya ubushyamirane namazi.
PTFE VERSUS TEFLON
Nubwo bitandukanye mubirango, PTFE na Teflon basangiye inkomoko hamwe nibintu.
PTFE
PTFE ni polymerike yubukorikori ikomoka ku guhuza imiti hagati ya karubone na fluor, ikoresha uburyo bwa radicals yubusa ikunda polymerize hamwe na tetrafluoroethylene.Ibi bikoresho byavumbuwe ku bw'impanuka mu 1938, ubwo umuhanga mu bya shimi wa DuPont Roy J. Plunkett yageragezaga gukora ubwoko bushya bwa firigo, akavanga ibyo bikoresho hamwe atazi uko byatera.
TEFLON
Kinetic Chemical, isosiyete ikora ubufatanye hagati ya DuPont na General Motors, yanditseho PTFE ku izina rya Teflon mu 1945. Muri rusange, Teflon ni PTFE.Ariko, PTFE iraboneka kandi munsi yandi mazina atandukanye, nka:
- Daikin-Polyflon
- Fluon
- Dyneon
UMUTUNGO
Ibintu byinshi bitandukanya PTFE nibindi bintu, harimo:
- Coefficient de fraisse nkeya: PTFE ifite coefficient ya gatatu yo hasi yo guteranya ibintu byose bizwi numuntu, bivuze ko mubyukuri
- Imikorere yubushyuhe bukabije: Ikigereranyo cya 600 K, PTFE ishonga kuri 327ºC cyangwa 620ºF, kandi ikora neza mubushyuhe buke nka −268ºC cyangwa −450ºF.
- Irwanya amazi: Amasaro y'amazi hejuru ya PTFE, bivuze ko ubuso buvuwe nibi bikoresho birwanya okiside.
- Kudakora: PTFE ntabwo ikora hamwe nibintu byinshi byangirika, bigatuma biba byiza gukoreshwa mumiyoboro, indangagaciro, kashe, na O-impeta.
URWEGO RW'AGATEGANYO RWA PTFE
Ubushyuhe buringaniye (-1,000F kugeza + 4,000F), kudakora, kurwanya amazi, hamwe no kugabanya ubukana bwa PTFE bituma biba ibikoresho byiza byo kubaka O-impeta kugirango ikoreshwe muburyo butandukanye.Iyi mitungo ituma PTFE O-impeta ihitamo neza kubirwanya ikirere kimwe nibisabwa birimo amashanyarazi hamwe nubushyuhe bwumuriro.
Bitewe n'ubucucike bwabo,PTFE O-impetantabwo "byashizweho-gushonga" - ahubwo, biranyeganyezwa kandi biracumura kugirango bitange ishusho ikenewe.
Kashe ya TEFLON / PTFE
O-impetabikozwe muri PTFE biboneka muburyo butandukanye bwinganda zisaba kashe zishobora kwihanganira ingorane.PTFE O-impeta igaragara muri porogaramu nyinshi zihura nimpamvu zikurikira:
| Porogaramu yo hejuru | Intege nke za mashini |
