Cov khoom siv zoo ntawm PTFE board

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 laus tshaj plaws ntawm cov yas.

Lubrication siab-yog qhov qis tshaj coefficient ntawm kev sib txhuam ntawm cov khoom siv tau.

Tsis-adhesion: nws yog qhov me me ntom ntom ntawm cov ntaub ntawv khoom thiab tsis ua raws li cov khoom siv. Kev sib txhuam coefficient ntawm cov khoom siv dag zog yog qhov tsawg heev, tsuas yog 1/5 ntawm cov polyethylene, uas yog qhov tseem ceeb ntawm perfluorocarbon nto. Ib qho ntxiv, vim tias cov tshuaj fluorine-carbon cov kab sib cuam tshuam hauv lub cev muaj zog tsawg heev, PTFE tsis nplaum.

Tsis muaj tshuaj lom-Nws yog lub cev tsis muaj zog thiab tsis muaj kev phiv tshuaj zoo li cov hlab ntshav dag thiab cov khoom nruab nrog cev hauv lub cev tau ntev.

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.

Kev tiv thaiv hluav taws xob Polytetrafluoroethylene muaj cov hluav taws xob tsis zoo tiv taus (104 rad), thiab nws degrades tom qab raug rau hluav taws xob hluav taws xob siab, thiab cov khoom siv hluav taws xob thiab cov khoom siv ntawm cov polymer tau txo qis. Daim ntawv thov Polytetrafluoroethylene tuaj yeem tsim los ntawm kev nrawm lossis ua kom tiav; nws kuj tseem tuaj yeem ua rau dej tawg rau txheej, dipping lossis ua cov fibers. Polytetrafluoroethylene yog dav siv raws li qhov siab thiab tsis kub tiv taus, cov khoom tiv taus xeb, rwb thaiv tsev cov ntaub ntawv, tiv thaiv lo lo, thiab lwm yam hauv nuclear zog, aerospace, hluav taws xob, hluav taws xob, tshuaj, tshuab, ntsuas, ntsuas, kev tsim, 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: Neutral.

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

Polytetrafluoroethylene (F4, PTFE) muaj cov kev ua tau zoo tshaj plaws: qhov kub tsis kam ua haujlwm ntev-siv 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 kuab tshuaj; Huab cua tsis kam-lub neej laus tshaj plaws hauv yas; siab lubrication-nrog qhov tsawg tshaj plaws coefficient ntawm kev sib txhuam (0.04) hauv yas; non-stickiness-nrog qhov me me ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntaws ntaws ntaws ntaws ntaws ntaws ntaws ntaws-tsis lo-nrog qhov me me ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntaws tsis muaj tshuaj lom-nrog lub cev tsis muaj zog; Cov khoom siv hluav taws xob zoo heev, nws yog cov khoom siv C-insulating zoo tshaj plaws.
