Dab tsi cov ntaub ntawv thiab qauv yuav tsum tau xaiv rau hydrochloric acid chaw tsim hluav taws xob?
Cov ntaub ntawv xaiv cov ntsiab lus rau cov pob zeb acid
1. tus yam ntxwv ntawm hydrochloric acid
Hydrochloric acid (cais cov tshuaj: HCl) {}}}}}}}} wide% in acid npuas) yog qhov tsis muaj zog-thaum lub thawv yog qhib, hydrogen tshuaj tshuaj chloride o roj volategizes thiab sib txuas nrog dej vapor nyob rau hauv huab cua los ua kom muaj cov cua daj cua dub {{4 4}}
2. qauv xaiv rau hydrochloric acid Chaw Thau Khoom caj npab
Vim nws corrosive thiab volrochloric acid yuav tsum muaj cov caj dab tshwj xeeb . tus qauv yogAl1412 nrog PTFE-Lined Kav, qhov twg:
"Al" txhais tau cov av-raws li cov kua thauj caj npab .
"1" qhia tau cov haujlwm ua haujlwm sab saum toj .
"4" Qhia tawm 4 tus txiv pob qij txha ntawm cov kua theem yeeb nkab .
"1" sawv cev rau ib qho kev sib txuas sab sauv-txuas cov yeeb nkab tawg .
"2" sawv cev rau cov kua qis theem theem sib txuas {{2 2}}
3.} cov khoom siv rau cov corrosion tsis kam
Muab cov khoom lag luam muaj zog ntawm hydrochloric acid, cia thiab cov khoom siv acid-resistant cov txheej txheem rau hydrochloric acid load loading npab muaj xws li:
PTFE hauv ob sab phlu: Cov khoom siv wetted (cov kav dej (cov kav dej, li qub) yuav tsum tau ua kom zoo nkauj ntawm hydfeethylene (sib xws nrog ntau ntau txog 37%).
Vapor Rov Qab System System: Vim yog cov hluav taws xob siab, lub chaw thau khoom sab caj dab yuav tsum tau nruab nrog Vapor rov qab los rau lub Tank Sealing Cap {.
Cov Khoom Siv Qauv:
Kev sib hloov sib koom ua ke: ua los ntawm 316L stainless hlau nrog PTFE daim foob ....
Cov caj npab sab nraud: carbon steel nrog anti-corrosion txheej (e {} cov hnab yas, nrog PTFE Liners hauv kev sib cuag nrog qhov nruab nrab.
4. Tus Qauv Kev Nyab Xeeb Kev Nyab Xeeb
Nkag Nkag Platform: Ib qho estrator automalator lossis Walkway yuav tsum tau nruab ib sab ntawm lub chaw thau khoom sab caj npab thiab lub tsheb loj los pab txhawb kev nyab xeeb thiab txo qis kev pheej hmoo {}}
Kev Tiv Thaiv Kev Tiv Thaiv: Tag nrho cov pob qij txha yuav tsum tau sim siab (1 {}}}} ptfe gaskets yog siv nyob rau hauv flanged sib txuas rau kev sib txuas sib txuas.
{{05. Kev txiav txim siab tseem ceeb rau cov khoom xaiv
Corrosion Kuj: PTFE yog qhov zoo tagnrho vim nws cov ntaub ntawv inertness, tab sis lwm cov ntaub ntawv xws li hastellloy c-276}} {degree) {{3}
Volatility Tswj: Lub chaw thau khoom thauj khoom (nrog Vapor rov qab) ua raws li EPA cov qauv rau volatile organic compound (voc) emissions .
Neeg Kho Tshuab Muaj Zog: Caj ces thauj khoom yuav tsum tiv thaiv axial loads los ntawm ptfe-lined pipes thaum muaj kev sib hloov ntawm 20th · m torque) .

Xaiv cov ntaub ntawv rau hydrochloric acid chaw nres tsheb caj npab yuav tsum tsis txhob muaj cov khoom siv tsis ua haujlwm (e {} g {} g., ASTM D1457 rau PTFE cov khoom lag luam) thiab yauv mus kuaj nruj ua ntej xa tawm .
