PTFE gasket

PTFE gaskets muaj cov khoom zoo heev ntawm kev nkag tau yooj yim, txias txaus tsis kam, ultra-low kub kuj, tsis muaj kuab paug, thiab yooj yim installation thiab disassembly. Nyob rau hauv ib qho me me pre-tightening quab yuam, nws tuaj yeem tiv taus qhov siab ntawm sab hauv txawm tias nyob rau hauv ib puag ncig kev hloov pauv siab. Nws yog qhov tsim nyog rau kev hnav tsis zoo los yog tsis sib xws thiab cov iav flange flanges tsis zoo thiab qhov kub thiab txias-hloov sealing zaus. Peb tuaj yeem xaiv Gore, Klinger, Garlock, Sealon thiab lwm cov ntawv nthuav dav PTFE rau cov neeg siv khoom los tsim cov gaskets xav tau rau cov neeg siv khoom.

Kub kub ua haujlwm-kub ua haujlwm tuaj yeem ncav cuag 250 ℃.

Tsawg kub tsis kam-muaj cov cuab yeej ua tau zoo; txawm tias qhov kub tau poob rau -196 ℃, nws tuaj yeem tswj tau 5% kev ncua ntev.

Corrosion resistance-Nws yog inert rau feem ntau cov tshuaj thiab cov kuab tshuaj, thiab tuaj yeem tiv taus cov kua qaub thiab alkalis, dej thiab ntau yam kuab tshuaj organic.

Huab cua tsis kam-muaj lub neej kev laus zoo hauv cov yas.

High lubrication-yog qhov qis coefficient ntawm kev sib txhuam hauv cov khoom siv.

Tsis-adhesion-nws txhais tau hais tias qhov nro saum npoo ntawm cov khoom siv me me thiab tsis ua raws li cov khoom siv. Nws cov khoom siv tshuab muaj qhov sib txhuam me me, uas tsuas yog 1/5 ntawm cov polyethylene. Qhov no yog ib qho tseem ceeb feature ntawm perfluorocarbon nto. Tsis tas li ntawd, vim hais tias cov fluorine-carbon saw intermolecular rog muaj tsawg heev, PTFE tsis nplaum.

Tsis muaj tshuaj lom thiab muaj teeb meem-nrog rau lub cev tsis muaj zog, raws li cov hlab ntsha thiab cov khoom nruab nrog cev tau cog rau hauv lub cev ntev ntev yam tsis muaj kev phiv tshuaj.

Cov khoom siv hluav taws xob Polytetrafluoroethylene muaj qhov qis dielectric tsis tu ncua thiab dielectric poob nyob rau hauv ntau qhov ntau, thiab muaj qhov ua kom tawg siab, ntim tsis kam thiab tiv taus arc.

Radiation resistance Polytetrafluoroethylene muaj cov hluav taws xob tsis zoo (104 rad), thiab nws degrades tom qab raug hluav taws xob hluav taws xob, thiab cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob ntawm cov polymer yog txo qis. Daim ntawv thov Polytetrafluoroethylene tuaj yeem tsim los ntawm compression lossis extrusion ua; nws tseem tuaj yeem ua rau hauv dej dispersion rau txheej, dipping lossis ua fibers. PTFE yog dav siv nyob rau hauv kub thiab tsis kub resistant, corrosion resistant cov ntaub ntawv, insulating cov ntaub ntawv, anti-stick coatings, thiab lwm yam nyob rau hauv nuclear zog, aerospace, electronics, hluav taws xob, tshuaj, machinery, instruments, meters, kev tsim kho, textiles, zaub mov thiab lwm yam kev lag luam.

Kev tiv thaiv kev laus ntawm huab cua: tiv thaiv hluav taws xob thiab qis permeability: raug mus rau huab cua mus sij hawm ntev, saum npoo thiab kev ua haujlwm tseem tsis hloov pauv.

Tsis-combustibility: Cov pa oxygen txwv qis dua 90.

Acid thiab alkali tsis kam: insoluble hauv cov kua qaub, muaj zog alkalis thiab cov kuab tshuaj organic.

Oxidation tsis kam: tiv taus xeb los ntawm cov muaj zog oxidants.

Acidity: nruab nrab.

Cov khoom siv dag zog ntawm PTFE yog qhov muag. Muaj lub zog qis heev.

Polytetrafluoroethylene (F4, PTFE) muaj cov kev ua tau zoo heev: kev kub siab ua haujlwm ntev-ntev kub ntawm 200 ~ 260 degrees, tsis kub tsis kam-tseem mos ntawm -100 degrees; corrosion kuj-ua hauj rau aqua regia thiab tag nrho cov organic solvents; Huab cua tsis kam-kev laus lub neej hauv cov yas; siab lubrication-nrog me me coefficient ntawm kev sib txhuam (0.04) hauv cov yas; tsis-stickiness-nrog tsawg nto nro nyob rau hauv cov ntaub ntawv uas tsis muaj adhesion ntawm tej yam khoom; non-toxic-nrog physiological inertness; Cov khoom siv hluav taws xob zoo heev, yog qhov zoo tshaj plaws C-theem insulating khoom.
