PTFE (Teflon) hauv Cov Kabmob Siv Hauv Cov Qauv Loj PTFE muaj qhov tshwj xeeb qis coefficient ntawm kev sib txhuam thiab siab tus kheej lubricating yam, tiv thaiv los ntawm yuav luag txhua yam tshuaj, thiab ib qho muaj peev xwm ua haujlwm nyob rau hauv qhov kub thiab txias.
Teflon puas zoo rau cov kabmob?
Nco Kashima. PTFE (polytetrafluoroethylene) yog cov khoom siv tshwj xeeb uas ua rau nws nrov heev rau cov kabmob yas.
Teflon bearing yog dab tsi?
POT-PTFE BEARING. POT BEARING. POT bearing yog tsim nyob rau hauv 1959 raws li ib tug lwm txoj rau hnyav steel zawv zawg bearings. Nws muaj voj voog tsis muaj roj hmab-padtag nrho nyob rau hauv lub lauj kaub hlau.
PTFE kev tsim kho yog dab tsi?
Polytetrafluoroethylene (PTFE) yog thermoplastic compound sau tseg rau nws cov tshuaj tseem ceeb heev inertness thiab kub tsis kam. Feem ntau ntsib raws li cov txheej uas tsis yog lo rau cov lauj kaub thiab cov lauj kaub nws yog qee zaum raug xa mus los ntawm lub npe lag luam 'Teflon' lossis 'Syncolon'.
YPuas yog PTFE yog Teflon?
Cov lus teb yooj yim yog tias lawv yog tib yam: Teflon ™ yog lub npe lag luam rau PTFE thiab yog lub npe lag luam uas siv los ntawm Du Pont tuam txhab thiab nws cov tuam txhab lag luam. (Kinetic uas thawj zaug sau npe cov cim lag luam & Chemours uas tam sim no muaj nws).

Vim li cas pinion bearings ua phem?
Failure from lubrication: Kwv yees li 80 feem pua ntawm pinion bearing tsis ua hauj lwm yog traceable rau tsis txaus lubrication. Qee zaum, nws tuaj yeem yog lubrication tsis txaus, lubricants tsis tsim nyog, lossis degradation ntawm lubricants vim qhov kub thiab txias.
Vim li cas cov khoom siv dielectric siv hauv capacitor?
Ib qho khoom siv dielectric yog siv los cais cov paib hluav taws xob ntawm lub capacitor. Cov khoom siv insulating no tseem ceeb txiav txim siab txog cov khoom ntawm cov khoom. Lub dielectric qhov tsis tu ncua ntawm cov khoom txiav txim siab npaum li cas ntawm lub zog uas lub capacitor tuaj yeem khaws cia thaum siv hluav taws xob.
Vim li cas cov alloys siv hauv cov khoom siv hluav taws xob cua sov?
Raws li peb paub alloys muaj siab resistivity thiab siab melting point piv rau cov hlau ntshiab. Yog li cov hlau tsis tuaj yeem yooj yim hlawv lossis oxidize ntawm qhov kub siab dua. Tam sim no raws li peb xav kom kub siab dua hauv cov khoom siv cua sov yog li peb siv cov alloys hauv cov khoom siv cua sov.
Vim li cas cov phiaj xwm tseem ceeb siv rau hauv kev siv nyiaj txiag thiab kev kwv yees?
Lub Rooj Milestones yog ib qho tseem ceeb tshaj plaws hauv koj txoj kev npaj ua lag luam. Nws teeb txoj kev npaj rau hauv cov tswv yim, cov ntsiab lus tseem ceeb, nrog cov peev txheej tiag, hnub kawg, thiab kev tswj xyuas lub luag haujlwm. Nws pab koj ua kom pom tseeb thaum koj tab tom sau koj txoj kev npaj ua lag luam, thiab tom qab ntawd, cov lus Milestones thiab cov phiaj xwm-vs.
Vim li cas gutta-percha siv hauv cov kwj dej hauv paus?
Cov txheej txheem yuav tsum ntxuav tawm cov kab hniav uas muaj kab mob, tshem tawm cov kab mob thiab tom qab ntawd muab cov hniav thiab muab khi. Gutta percha yog cov tshuaj uas yog siv los sau cov hniav kom tsis txhob kis kab mob. Gutta percha yog ib qho thermoplastic filling uas yog cua sov thiab ces nias rau hauv cov kwj hniav.
