Teflon insulated hlau yog hais txog cov hlau insulated ua los ntawm fluoroplastic (ETFE), feem ntau hu ua fluoroplastic rwb thaiv tsev, thiab qhwv nrog hlau conductors. ETFE yog tus cwj pwm los ntawm kev ua haujlwm zoo thiab molding, sib npaug lub cev lub zog, zoo mechanical toughness, thiab zoo heev rays. Cov khoom siv muaj kev tiv thaiv corrosion ntawm polytetrafluoroethylene, kov yeej qhov tsis adhesion ntawm polytetrafluoroethylene rau hlau, Tsis tas li ntawd, nws qhov nruab nrab linear expansion coefficient yog ze rau ntawm cov hlau, ua ETFE (F-40) zoo tagnrho cov khoom siv nrog hlau.
Cov yam ntxwv ntawm Teflon insulated hlau
1. Kub kub tsis kam: PTFE zaj duab xis muaj cov cua kub zoo heev. Nws tuaj yeem tiv taus qhov kub siab txog 300 ℃ hauv ib lub sijhawm luv luv, thiab tuaj yeem siv tsis tu ncua ntawm 240 ℃ thiab 260 ℃ feem ntau, nrog kev ruaj ntseg zoo heev.
2. Tsawg kub tsis kam - zoo mechanical toughness; Lub elongation ntawm 5% tuaj yeem tswj tau txawm tias qhov kub thiab txias poob rau - 196 ℃.
3. Corrosion kuj - PTFE yog dav siv nyob rau hauv kev lag luam uas yuav tsum tau kub kub kuj thiab siab viscosity. Nws kuj tseem siv tau los ua cov kua qaub super uas muaj zog Z - fluoroantimonate.
4. Tsis muaj tshuaj lom: Nws yog lub cev tsis muaj zog thiab tuaj yeem cog rau hauv lub cev raws li cov hlab ntsha thiab cov khoom nruab nrog ntev ntev yam tsis muaj kev phiv tshuaj.
5. Hluav taws xob rwb thaiv tsev - nws tuaj yeem tiv taus 6000 V high voltage.
6. Atmospheric aging kuj: hluav taws xob tiv thaiv thiab tsis tshua muaj permeability: qhov saum npoo thiab kev ua tau zoo nyob twj ywm tsis hloov tom qab lub sij hawm ntev raug rau huab cua.
7. Tsis yog combustibility: cov pa txwv qhov ntsuas qis dua 90.
8. Acid thiab alkali tsis kam: insoluble nyob rau hauv muaj zog acids, bases thiab organic solvents.
9. Kev ua haujlwm hluav taws xob - Teflon muaj qhov tsis tshua muaj hluav taws xob tsis tu ncua thiab dielectric poob nyob rau hauv ntau zaus, thiab siab tawg voltage, ntim resistivity thiab arc tsis kam.
