Ntawm ntau qhov kev lag luam li qub, fluorine-lined li qub yog qhov tseem ceeb hauv kev tuav cov xov xwm hnyav nrog lawv cov kev tiv thaiv zoo heev thiab tshuaj lom neeg ruaj khov. Txawm li cas los xij, ntxiv rau kev tiv thaiv corrosion, qhov kub thiab txias tsis kam ntawm fluorine-lined li qub kuj yog ib qho tseem ceeb uas yuav tsum tau xav txog hauv ntau daim ntawv thov kev lag luam. Puas yog fluorine-lined li qub tiv taus qhov kub thiab txias?
Ua ntej, qhov tseem ceeb ntawm fluorine-lined li qub yog tias sab hauv ntawm lub cev valve feem ntau yog them nrog txheej ntawm polytetrafluoroethylene (PTFE) lossis lwm yam polymers. Cov ntaub ntawv no tau siv dav hauv cov li qub vim lawv cov tshuaj inertness thiab corrosion kuj, zoo tiv thaiv kev yaig ntawm ntau cov tshuaj. Txawm li cas los xij, qhov kub tsis kam ntawm fluoropolymer yog qhov txwv. Feem ntau, qhov kub tsis kam ntawm PTFE tuaj yeem ncav cuag li 200 degree. Tom qab tshaj qhov ntsuas kub no, PTFE tuaj yeem pib muag lossis txawm tias decompose, cuam tshuam rau nws lub zog thiab kev sib khi.
Txawm li cas los xij, qee qhov tshwj xeeb fluoropolymers, xws li polytetrafluoroethylene propylene (PFA) thiab polytetrafluoroethylene propylene (FEP), tej zaum yuav tsim nyog rau cov ntawv thov kub dua. Cov ntaub ntawv no muaj qhov ntsuas kub siab dua; PFA tuaj yeem tiv taus kub txog 300 degree, thaum FEP nyob nruab nrab ntawm 200 degree thiab 204 degree. Qhov no ua rau cov roj-lined li qub los tiv thaiv ntau qhov chaw muaj kev lag luam thiab cov ntawv thov kub siab dua.
Qhov tseem ceeb, fluorine-lined li qub 'kub kub tsis kam yog nyob ntawm cov khoom siv hauv ob sab phlu, valve tsim, thiab siv cov xwm txheej. Cov yam ntxwv xws li cov qauv valve, cov khoom siv lub cev lub cev, thiab kev ua haujlwm siab tuaj yeem cuam tshuam rau lawv qhov kev ua tau zoo hauv qhov kub thiab txias. Yog li ntawd, thaum xaiv cov fluorine-lined li qub, cov neeg siv yuav tsum xav txog cov xwm txheej no kom ntseeg tau tias lub valve tuaj yeem ua haujlwm zoo thiab ua tau zoo raws li kev ua haujlwm tshwj xeeb.
Tsis tas li ntawd, txawm hais tias qhov kub-kub tsis kam ntawm fluorine-lined li qub yog txwv, lawv tseem yog ib qho kev xaiv zoo tshaj plaws hauv ntau daim ntawv thov uas yuav tsum muaj kev tiv thaiv corrosion thiab kub dua. Hauv kev siv tiag tiag, fluorine-lined li qub feem ntau pom muaj nyob rau hauv kev lag luam tshuaj, tshuaj, thiab khoom noj khoom haus, uas xav tau cov tshuaj tiv thaiv zoo thiab qee qhov kev ntxhov siab thermal.
