Koj puas tau ntsib qhov xwm txheej no? Cov khoom siv hlau ntawm cov teeb pom kev zoo uas koj yuav tau pib qhia cov cim ntawm corrosion ntawm qhov chaw tom qab siv lub sijhawm. Qhov no qhia tau tseeb tias qhov zoo ntawm cov khoom siv teeb pom kev zoo tsis yog raws li tus qauv. Yog tias koj xav paub vim li cas tom qab qhov no, hnub no peb yuav qhia tias nws yog txhua yam cuam tshuam nrog "kev ntsuas ntsev"!
Dab tsi yog Kev Ntsuas Tshuaj Tsuag?
Kev Ntsuas Tshuaj Ntsev yog ib qho kev ntsuas ib puag ncig siv los ntsuas qhov kev tiv thaiv corrosion ntawm cov khoom lossis cov khoom siv hlau. Nws simulates ib puag ncig ntsev tsuag los ntsuas qhov ua haujlwm ntawm cov ntaub ntawv nyob rau hauv cov xwm txheej zoo li no thiab ntsuas lawv cov kev ua tau zoo thiab kev ua neej nyob ntev hauv qhov chaw corrosive.
Experimental Classification:
1. Neutral Salt Spray (NSS)
Neutral Salt Spray Test yog qhov ntxov tshaj plaws thiab feem ntau siv dav hauv kev ntsuas kev ntsuas corrosion. Feem ntau, nws siv 5% sodium chloride ntsev dej tov nrog tus nqi pH hloov mus rau qhov nruab nrab (6.5-7.2) rau kev siv tshuaj tsuag. Qhov ntsuas kub yog khaws cia ntawm 35 ° C, thiab cov ntsev pos huab deposition yuav tsum nyob nruab nrab ntawm 1-3 ml / 80cm²·h, feem ntau 1-2 ml / 80cm²·h.
2. Acetic Acid Salt Spray (AASS)
Acetic Acid Salt Spray Test tsim los ntawm Neutral Salt Spray Test. Nws suav nrog ntxiv glacial acetic acid rau 5% sodium chloride tov, txo cov pH mus rau ib ncig ntawm 3, ua rau cov kua qaub, thiab yog li hloov cov ntsev pos huab los ntawm nruab nrab mus rau acidic. Nws tus nqi corrosion yog li peb zaug sai dua NSS kuaj.
3. Copper Accelerated Acetic Acid Salt Spray (CASS)
Copper Accelerated Acetic Acid Salt Spray Test yog qhov tsis ntev los no tau tsim cov ntsev tsuag tshuaj tiv thaiv kab mob sai sai rau txawv teb chaws. Qhov ntsuas kub yog 50 ° C, nrog ib qho me me ntawm tooj liab ntsev (tooj liab chloride) ntxiv rau cov ntsev ntsev, uas ua rau kom muaj zog corrosion. Nws tus nqi corrosion yog kwv yees li 8 npaug sai dua NSS kuaj.
4. Alternating Salt Spray (ASS)
Alternating Salt Spray Test yog ib qho kev ntsuam xyuas ntsev tsuag uas ua ke nrog cov tshuaj ntsev nruab nrab nrog cov av noo tas li. Nws yog feem ntau siv rau cov kab noj hniav-hom tag nrho-tshuab cov khoom, inducing ntsev tsuag corrosion tsis tsuas yog nyob rau hauv cov khoom nto, tab sis kuj nyob rau hauv lub permeation ntawm cov av noo. Cov khoom lag luam raug hloov pauv ntawm cov huab cua ntsev thiab cov av noo, ntsuas kev hloov pauv hauv hluav taws xob thiab kev ua haujlwm ntawm tag nrho cov khoom siv tshuab.
Puas yog Liper cov khoom siv teeb pom kev zoo kuj tau kuaj tshuaj ntsev?
Lo lus teb yog Yes! Liper cov ntaub ntawv hlau rau lub teeb thiab luminaires yog tsim raws li cov qauv thoob ntiaj teb. Raws li IEC60068-2-52 tus qauv, lawv tau dhau los ua qhov kev ntsuas nrawm nrawm nrog rau kev tshuaj tsuag tas li rau 12 teev (rau hlau plating). Tom qab kev sim, peb cov ntaub ntawv hlau yuav tsum tsis muaj cov cim ntawm oxidation lossis xeb. Tsuas yog tom qab ntawd Liper cov khoom siv teeb pom kev zoo tuaj yeem kuaj thiab tsim nyog.
Peb cia siab tias tsab xov xwm no yuav pab peb cov neeg siv khoom nkag siab txog qhov tseem ceeb ntawm kev ntsuas tshuaj ntsev. Thaum xaiv cov khoom siv teeb pom kev zoo, nws yog ib qho tseem ceeb los xaiv cov kev xaiv zoo. Ntawm Liper, peb cov khoom raug kuaj xyuas nruj, suav nrog kev ntsuas tshuaj ntsev, kev ntsuas kev ua neej, kev ntsuas dej, thiab kev sib xyaw ua ke, thiab lwm yam.
Cov kev kuaj xyuas zoo no ua kom ntseeg tau tias Liper cov neeg siv khoom tau txais cov khoom lag luam zoo, txhim khu kev qha teeb pom kev zoo, yog li txhim kho peb cov neeg siv khoom lub neej zoo thiab kev txaus siab tag nrho.
Raws li cov kws tshaj lij teeb pom kev lag luam, Liper tau ua tib zoo xaiv cov khoom siv, tso cai rau koj xaiv thiab siv peb cov khoom nrog kev ntseeg siab.
