# PFA Rhaub Rhaub puas ua tau zoo dua lwm yam los tiv thaiv -cov khoom siv hluav taws xob cua sov hauv qhov chaw muaj tshuaj lom neeg hnyav? Raws li kev lag luam tshuaj lom neeg txav mus rau ntau txoj kev sib xyaw ua ke corrosive, cov khoom siv cua sov xws li stainless hlau, titanium thiab quartz tubes feem ntau ntsib teeb meem hauv lub cev thaum ntsib kev sib xyaw ua ke ntawm cov kua qaub, alkali thiab cov kuab tshuaj organic. PFA heaters coated nrog perfluoroalkoxy resin yog tsim tshwj xeeb los tiv thaiv ultra- hnyav ntau- corrosion ua hauj lwm tej yam kev mob. Ntau tus neeg tsim khoom thiab cov thawj coj tsim khoom tsis meej pem txog seb PFA cov khoom siv cua sov puas tuaj yeem dhau los ua qhov kawg tiv thaiv - kev xaiv cua sov thiab hloov peb hom cua sov raj uas tau hais ua ntej. Los ntawm kev khawb rau hauv cov qauv molecular ntawm cov khoom siv PFA, cov txiaj ntsig kev ua haujlwm thiab kev txwv tsis pub siv, tsab xov xwm no txheeb xyuas qhov tseem ceeb ntawm kev sib tw thiab daim ntawv thov ntawm kev tiv thaiv -corrosion PFA heaters. PFA yog cov khoom siv fluoropolymer hloov kho nrog cov tshuaj lom neeg cov saw hlau ruaj khov heev. Nws tsis tsim cov tshuaj tiv thaiv nrog yuav luag tag nrho cov acids muaj zog, muaj zog alkalis, cov tshuaj halogen thiab cov organic chemical reagents nyob rau hauv qhov tso cai ua haujlwm kub. Qhov sib txawv ntawm cov hlau cua sov cov raj uas tso siab rau cov yeeb yaj kiab uas siv cov yeeb yaj kiab thiab cov quartz tubes uas nyob ntawm inert silica muaj pes tsawg leeg, PFA tsim cov txheej txheem tiv thaiv seamless ntawm txheej txheej ntawm cov tub ntxhais cua sov sab hauv, tshem tawm tag nrho cov cua sov los ntawm cov kua corrosive. Cov qauv cladding no hauv paus tsis txhob perforation thiab leakage tshwm sim los ntawm kev sib cuag ncaj qha ntawm cov khoom siv cua sov thiab qhov nruab nrab. Tsis tas li ntawd, lub ntsej muag du ntawm PFA yog ib qho nyuaj rau txuas cov av, nplai thiab cov tshuaj lom neeg, uas txo cov zaus ntawm cov khoom siv tu thiab tu thaum lub sijhawm ua haujlwm ntev -. Cov lus hauv qab no sib piv cov ntsuas kev ua haujlwm tseem ceeb ntawm plaub lub hauv paus los tiv thaiv- cov khoom siv cua sov.|Cov cuab yeej cua sov hom|Kev tiv thaiv rau Mixed Acid{17}}Alkali Solution|Risk of Medium Contamination|Qhov siab tshaj plaws ntev -lub sij hawm ua haujlwm kub|Mechanical Anti-kev sib tsoo muaj peev xwm|Tus nqi siv tag nrho|| ----|----|----|----|----|----|| PFA rhaub|Sab saum toj qib, tsis muaj tshuaj tiv thaiv|Tsis muaj kab mob|260 degree|Nruab nrab, txheej yuav tev nyob rau hauv nruj khawb|Nruab nrab-siab|| 316 Stainless Hlau Cua sov Tube|Tsis zoo, puas sai sai hauv cov kua sib xyaw corrosive|Kab hlau ion tawg|580 degree|Muaj zog heev|Tsawg|| Titanium cua sov Tube|Zoo heev tiv thaiv ib leeg acid/chloride, tsis muaj zog alkali|Yuav luag tsis muaj kuab paug|800 degree|Muaj zog|Siab|| Quartz cua sov Tube|Zoo tiv thaiv acid, hnyav corroded los ntawm muaj zog alkali|Tsis muaj kuab paug|1200 degree|Kho siab heev|Nruab nrab|Raws li cov ntaub ntawv teev tseg hauv lub rooj, qhov zoo tshaj plaws ntawm PFA cov cua sov yog lawv qhov kev hloov mus rau qhov sib xyaw corrosive ib puag ncig, uas tsis tuaj yeem sib phim los ntawm lwm yam peb hom cua sov. Hauv electroplating khib nyiab kho, tshuaj tua kab raw khoom synthesis thiab luam tawm Circuit Board etching txheej txheem, cov cua kub nruab nrab feem ntau muaj ntau yam corrosive nyob rau tib lub sijhawm. Stainless hlau raj yuav xeb nyob rau hauv lub lis piam, titanium cov ntaub ntawv yuav eroded los ntawm high-concentration alkaline cawv, thiab quartz hlab yuav tawg thiab tawg yooj yim nyob rau hauv cov kua. Hauv qhov sib piv, PFA cov cua sov tuaj yeem ua haujlwm ruaj khov rau ntau tshaj ob xyoos hauv qhov sib xyaw tshuaj hnyav hnyav. Tsis tas li ntawd, cov cuab yeej rwb thaiv tsev ntawm PFA cov khoom siv tau zoo tiv thaiv hluav taws xob txaus ntshai txawm tias cov txheej txheem tiv thaiv sab nrauv yog hnav me ntsis, txhim kho kev nyab xeeb ntawm cov khoom siv hluav taws xob hauv chav ua haujlwm. Txawm li cas los xij, PFA cov cua sov muaj qhov txwv tsis pub hloov. Lawv qhov kub siab tshaj plaws ua haujlwm tau zoo yog qis dua cov hlau thiab quartz cua sov raj, yog li lawv tsis tuaj yeem siv rau hauv qhov kub kub qhuav cua sov tshaj 260 degrees Celsius. Cov khoom tawv tawv scraping ntawm qhov chaw yuav ua rau cov txheej txheej, ua rau cov tub ntxhais cua sov sab hauv raug rau cov kua corrosive thiab ua tsis tau sai. Lub caij no, tus nqi ua haujlwm customized ntawm ib qho PFA cladding yog siab dua li qub 316 stainless hlau cua sov raj, yog li nws tsis yooj yim sua kom xa cov cua sov rau hauv cov dej kub yooj yim lossis cov xwm txheej tsis zoo. Txhawm rau ua kom tiav, PFA cov cua sov yog qhov kev xaiv zoo tshaj plaws rau kev tiv thaiv corrosion cua sov nyob rau hauv cov kua qaub thiab alkali sib xyaw tshuaj, nrog rau qhov tsis sib xws ntawm kev tiv thaiv corrosion ntawm plaub pawg. Txawm li cas los xij, vim qhov kub thiab txias ntawm lub qab nthab thiab qhov chaw khawb qhov tsis xws luag, nws tsis tuaj yeem ua cov khoom cua sov thoob ntiaj teb. Cov tuam txhab lag luam yuav tsum xaiv PFA cov cua sov tsuas yog thaum cuam tshuam nrog kev sib xyaw corrosive media, thiab xaiv titanium, quartz lossis 316 stainless hlau cua sov raj raws li qhov kub thiab txias xav tau rau lwm yam kev sib txuas.
