Kev ua haujlwm tseem ceeb
Kev tiv thaiv cathodic ntawm tus qauv nws tus kheej tsis cuam tshuam; Lub tsev tiv thaiv cathodic yuav tsis ua rau galvanic corrosion vim grounding.
Scope ntawm daim ntawv thov
Zinc earthing electrode tuaj yeem raug nqi tooj liab lossis steel earthing electrode siv yav dhau los hauv kev tsim vaj tsev, thiab daws qhov teeb meem ntawm cathodic tiv thaiv thiab earthing tib lub sijhawm, uas ua rau txo qis kev nqis peev thiab cov nqi ntawm cov engineering.
Ua tsaug
(1) Kev tiv thaiv cathodic ntawm tus qauv nws tus kheej yuav tsis cuam tshuam.
(2) Yog tias kev tiv thaiv cathodic ntawm lub tsev tsis ua rau galvanic corrosion vim yog av.
Zinc grounding roj teeb los ntawm ib khub ntawm qhov sib npaug ze los yog plaub zinc alloy sacrificial anode rods, nruab nrab sib cais los ntawm insulating ncoo, thiab ces ua ke nyob rau hauv ib tug tag nrho cov ntaub ntawv ntawm paj rwb hnab, tiv thaiv lub vaj los yog yeeb nkab sab high voltage surge ntawm kev puas tsuaj ntawm lub rwb thaiv tsev sib koom ua ke, flange, nyob ze ntawm cov yeeb nkab rwb thaiv tsev cov cuab yeej yuav tsum tau muab tso rau hauv av, los ntawm kev sib txuas cov hlau lead hauv ob sab ntawm cov khoom siv rwb thaiv tsev (cov rwb thaiv tsev sib koom lossis flange), txhawm rau tiv thaiv qhov hluav taws xob siab los ntawm kev puas tsuaj, tib lub sijhawm. Cov xwm txheej niaj hnub grounding roj teeb kuj tseem siv tau los tiv thaiv cov kav dej.
Cov teeb meem xav tau kev saib xyuas
Thaum siv hauv av, cov khoom ntim yuav tsum tau siv rau hauv kev faib ua feem ntawm 75% gypsum, 20% bentonite thiab 5% sodium sulfate.
Tus txheej txheem tswj hwm
ASTM-B418 / GB / T 4950-2002
Kev sib xyaw thiab kev siv
Lub ntiaj teb roj teeb muaj ib khub los yog plaub zinc alloy sacrificial anode rods nyob rau hauv parallel, sib cais los ntawm insulating pad blocks, uas yog ces muab tso rau ua ke nyob rau hauv paj rwb hnab nrog filling cov ntaub ntawv thiab welded los ntawm cov hlau lead cable rau ob sab ntawm lub rwb thaiv tsev ntaus ntawv (insulating sib koom. los yog flange) los tiv thaiv kev puas tsuaj los ntawm hluav taws xob muaj zog.
