Yuav ua li cas PTFE piv rau PEEK rau Thaum tshav kub kub Exchanger Tubing nyob rau hauv Mixed Acid Ib puag ncig?

PTFE yog tus qauv kub rau kev siv tshuaj lom neeg thoob ntiaj teb, tab sis PEEK- siab -kev ua tau zoo thermoplastic- tau nce ntxiv rau kev tshawb fawb rau cov cua kub exchanger tubing qhov twg siab dua txhua yam lub zog los yog kub muaj peev xwm yuav tsum tau. Txawm li cas los xij, PEEK tsis tshua muaj tshuaj tiv thaiv thiab yuav tsum tau xaiv los txiav txim siab txog qhov tshwj xeeb ib puag ncig.

PTFE vs PEB
Ob leeg PTFE thiab PEEK yog cov khoom siv rau cov cua kub exchanger tubing tab sis qhov tseem ceeb ntawm cov tshuaj tiv thaiv, thermal kev ua tau zoo thiab lub zog txhua yam yuav txiav txim siab seb qhov twg yog qhov tsim nyog rau cov xwm txheej sib xyaw.

PTFE (Polytetraflouroethylene)
Ib qho ntawm cov yam ntxwv ntxim nyiam tshaj plaws ntawm PTFE yog nws yuav luag universal tshuaj tsis kam. Nws yog ib qho kev xaiv zoo tshaj plaws nyob rau hauv cov xwm txheej uas cov tshuaj sib haum xeeb yog qhov tseem ceeb. Nws tiv taus rau feem ntau cov kua qaub, cov hauv paus thiab cov kuab tshuaj, tshwj tsis yog rau cov hlau alkali molten thiab qee cov tshuaj fluorinating. PTFE feem ntau ua tau zoo nyob rau hauv cov kev pab cuam tshav kub txog li 110 degree.

Ib qho txiaj ntsig tseem ceeb ntawm PTFE yog nws qhov yooj yim thiab tsis muaj zog uas ua rau nws nqus cov neeg kho tshuab kev ntxhov siab yam tsis muaj kev sib cais lossis tawg. Qhov no txhais tau tias nws tsim nyog rau cov ntawv thov uas hloov tau yooj yim thiab ua haujlwm rau cov tshuaj hnyav hnyav. Txawm li cas los xij, qhov tsis zoo yog tias PTFE muaj lub zog tsis zoo rau cov neeg kho tshuab piv rau lwm cov ntaub ntawv xws li PEEK thiab tej zaum yuav tsis ua haujlwm zoo nyob rau hauv siab - qhov chaw siab.

PEEK (Polyetheretherketone)
PEEK muaj ntau yam tshuaj tiv thaiv me dua li PTFE tab sis muaj zog dua txhua yam thiab tuaj yeem tiv taus qhov kub thiab txias. Qhov kev pabcuam siab tshaj plaws tuaj yeem ncav cuag 250 degree. Nws tiv taus ntau cov kuab tshuaj organic thiab dav spectrum ntawm cov kua qaub xws li sulfuric acid, hydrochloric acid thiab phosphoric acid. Txawm li cas los xij, PEEK raug tawm tsam los ntawm cov concentrated nitric acid, sulfuric acid (tshaj 80 degree) thiab halogens, yog li cov tshuaj tiv thaiv ntawm PEEK tsis yog dav li PTFE.

PEEK muaj lub zog tensile siab, ua rau nws siv tau hauv cov ntawv thov siab. PEEK yog cov khoom siv tawv heev thiab tsis hloov pauv li PTFE. Qhov no tuaj yeem ua rau muaj kev cuam tshuam hauv qee qhov kev siv. Tsis tas li ntawd, cov thermal conductivity ntawm PEEK yog kwv yees li 0.25 W / m·K, piv rau PTFE, qhia tias qhov txiaj ntsig ntawm PEEK so ntau dua hauv nws cov khoom siv thiab thermal ntau dua li nws muaj peev xwm thauj cov cua sov kom zoo.

Yuav siv PTFE thiab PEEK li cas
PTFE feem ntau xaiv rau cov ntawv thov uas muaj tshuaj tiv thaiv rau ntau yam ntaub ntawv xav tau. Qhov no yog rooj plaub rau ib puag ncig nrog cov kua qaub sib txawv, cov kuab tshuaj thiab cov hauv paus, qhov uas tsis muaj kev phom sij ntawm kev tsis sib haum xeeb. Vim nws muaj peev xwm ua hauj lwm ntawm qhov kub thiab txias (txog 110 degree) nws yog qhov haum rau corrosive tej yam kev mob ntawm nruab nrab kub.

Ntawm qhov tod tes, PEEK yog qhov zoo dua rau cov ntawv thov uas muaj qhov kub thiab txias, siab siab thiab cov txheej txheem chemistry paub ntau dua thiab tuaj yeem tswj tau tas li. Ntawm qhov kub ntawm 150℃lossis siab dua, PEEK cov khoom siv hluav taws xob kub hloov pauv tau dhau los ua qhov kev xaiv tseem ceeb. Qhov no yog qhov tseeb tshwj xeeb tshaj yog thaum lub kaw lus yuav tsum xa cov neeg kho tshuab lub zog los tswj kev kub siab los yog cov kua dej aggressive dynamics.

Qhov sib txawv tseem ceeb yog tias PEEK kim dua PTFE vim nws muaj cov yam ntxwv ua tau zoo dua thiab cov txheej txheem tsim khoom ntau dua. Yog li qhov kev xaiv yog kev sib haum xeeb ntawm kev xav tau kev ua haujlwm thiab tus nqi ntawm cov khoom siv.

Kev sib piv ntawm PTFE thiab PEEK Heat Exchange Tubing
Cov lus hauv qab no qhia txog qhov sib txawv tseem ceeb ntawm PTFE thiab PEEK raws li lawv cov kev siv hauv cov khoom siv hluav taws xob sib txuas:

Property PTFE PEEK
Chemical Resistance Ze rau universal (tsis suav cov molten alkali hlau thiab tej yam fluorinating agents) Resistant rau feem ntau acids (tsis suav nrog khaus nitric thiab sulfuric acids siab tshaj 80 degree, halogens)
Max Kev Pab Cuam Kub ~ 110℃txog 250 degree
Mechanical Strength Tsawg zog, siab flexiblityHigh tensile lub zog tawv
Thermal Conductivity ~ 0.25 W/m·K ~ 0.25 W/m·K Tus Nqi Tsis tshua kim Feem ntau siab dua
Cov ntsiab lus
PEEK txhim khu lub pas dej ua ke ntawm cov ntaub ntawv muaj rau corrosion resistant tshav kub exchangers, tshwj xeeb tshaj yog rau kub thiab siab daim ntaub ntawv. Nws tsis, txawm li cas los xij, hloov universal tshuaj inertness ntawm PTFE . PTFE tseem yog cov khoom xaiv rau tshuaj tiv thaiv nyob rau hauv ntau yam mob. PEEK yog qhov tsim nyog rau cov ntawv tshwj xeeb uas lub zog, kub tsis kam thiab tshuaj lom neeg sib xyaw ua ke tau ua tib zoo txhais.

Hauv kev xyaum, kev xaiv cov khoom siv rau cov cua kub exchanger tubing yuav tsum tau ua raws li cov txheej txheem chemistry, kev khiav hauj lwm kub thiab txhua yam uas yuav tsum tau muaj ntawm cov txheej txheem tshwj xeeb. Paub txog cov subtleties ntawm PTFE vs PEEK tshav kub exchanger tube guarantees cov khoom zoo tshaj plaws yog xaiv los ua kom txaus siab rau cov tshuaj thiab lub cev xav tau ntawm daim ntawv thov.
