Cov txheej txheem tseem ceeb rau kev txiav txim siab yog tias magnesium oxide rwb thaiv tsev txheej yog damp yog ntsuas nws cov rwb thaiv tsev tiv thaiv, ua ke nrog kev ntsuam xyuas dav dav ntawm nws cov tsos thiab kev ua haujlwm. Nyob rau hauv ib txwm muaj xwm txheej, lub rwb thaiv tsev tiv thaiv ntawm magnesium oxide rwb thaiv tsev txheej yuav tsum siab tshaj los yog sib npaug rau 100 MΩ. Yog tias nws qis dua 10 MΩ, nws suav tias yog qhov ntub dej loj heev.
1. Txoj kev tshawb nrhiav tseem ceeb
Rwb thaiv tsev Resistance Test (Feem ntau ncaj qha thiab siv tau)
Siv lub 2500V megohmmeter los ntsuas qhov rwb thaiv tsev tiv thaiv ntawm cov cua sov thiab cov hlau casing nyob rau hauv lub hwj chim - tawm thiab cua txias.
Rwb thaiv tsev nyob rau hauv cov khoom tshiab los yog nyob rau hauv qhuav tej yam kev mob yog feem ntau> 500 MΩ;
Ntau dua lossis sib npaug rau 100 MΩ: Zoo- qhuav;
10-100 MΩ: me ntsis dampness tshwm sim, yuav tsum tau saib xyuas;
< 10 MΩ: Severely damp, must be addressed.
Nws raug pom zoo kom sim txhua hli. Yog tias pom qhov poob qis ntawm 50 MΩ mus rau 2 MΩ, nws qhia tau hais tias dampness yog tsim.
Lub Hwj Chim- ntawm Txoj Kev Saib Xyuas (Kev Txiav Txim Siab): Cov xwm txheej hauv qab no thaum lub sijhawm ua haujlwm ntawm cov cuab yeej siv yuav qhia tau tias cov dej nkag mus: Nquag ua rau muaj kev tiv thaiv cov dej xau los yog kev ceeb toom tsis raug hauv av los ntawm tus maub los; Txo cua sov efficiency thiab qeeb kub nce; Cov khoom siv hluav taws xob zoo li qub tab sis tsis muaj hluav taws xob tawm (tejzaum nws yog vim qhov luv luv ua rau lub cua sov tawg).
Kev Ntsuam Xyuas Kev Pom Zoo: Txheeb xyuas seb cov kab hluav taws xob puas muaj xim dub, xeb, muaj dej stains, lossis dawb crystals (magnesium hydroxide); Xyuas seb cov hlau casing muaj bulges, kab nrib pleb, los yog nyob rau hauv lub expansion expansion (ntws nkag ua rau MgO + H₂O → Mg(OH)₂, ua rau lub ntim expansion); Xyuas seb cov nplaum nplaum puas muaj hnub nyoog thiab tawg, tso cai rau cov dej nkag mus.
2. Feem ntau ua rau muaj kev nqus dej noo

Ua rau |
Kev piav qhia |
|
Kev nthuav tawm rau Humid Ib puag ncig |
Magnesium oxide yog cov khoom ntxeem tau thiab yooj yim nqus dej los ntawm huab cua, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig nrog cov av noo> 60%. |
|
Sealing Failure |
Kev sib khi tsis zoo ntawm cov pob qij txha thiab cov hlua hluav taws xob yog qhov ua rau muaj kev cuam tshuam ntawm cov dej noo. |
|
Kev khaws cia tsis raug |
Ntev - lub sij hawm cia yam tsis muaj dej noo - pov thawj los yog tsis ua ntej - qhuav ua ntej siv. |
|
Nquag Kub Cycling |
Hloov cov kub thiab txias txias yooj yim tsim condensation, accelerating internal noo noo nqus. |
High -purity magnesium oxide (99.9% lossis siab dua) lossis cov ntaub ntawv coated nrog silica tuaj yeem txo hygroscopicity.
3. Cov lus pom zoo

Qhov xwm txheej |
Kev pom zoo |

Rwb thaiv tsev tsis kam <10 MΩ |
Hloov cov cua sov tam sim ntawd; tsis kho ntawm -site. |
|
Rwb thaiv tsev tsis kam 10-100 MΩ |
thiab tsis tu ncua kev hloov pauv yuav tsum tau npaj kom tsis txhob ua tsis tiav tam sim ntawd. |
|
Tsuas yog cov kab hluav taws xob terminals yog damp thiab qhov ntev tso cai. |
Cov ntu ntub dej tuaj yeem raug txiav tawm thiab rov- crimped, tab sis ua tiav sealing thiab waterproofing yuav tsum tau xyuas kom meej. |
Nyob rau hauv siab - yuav tsum tau scenarios xws li txhaj tshuaj molding thiab tshuaj sterilization, rwb thaiv tsev tsis kam <10 MΩ yog suav hais tias yog tsis ua hauj lwm thiab yuav tsum tau hloov.
