Magnesium chloride board muaj qhov toughness zoo thiab hluav taws kub, tab sis nws kuj muaj teeb meem xws li kev nqus dej noo, zoo li scumming, thiab corrosion ntawm steel qauv.Nyob rau hauv daim ntawv thov steel qauv enclosure board, tam sim no nyob rau hauv Beijing thiab Tianjin thiab lwm qhov chaw, magnesium chloride board raug txwv thiab txwv.Vim nws qhov tsis xws luag, magnesium chloride board yog qhov nyuaj rau nkag mus rau hauv cov khoom siv hauv tsev loj, thiab hauv kev tsim steel qauv prefab, vim nws cov corrosion ntawm steel qauv, nws yog txwv tsis pub siv kiag li.
Magnesium Oxide Sulfate Board yog raws li kev hloov kho cov khoom siv ntshiab magnesium sulfate, uas ua tiav cov txiaj ntsig ntawm magnesium chloride board thaum tshem tawm nws qhov tsis xws luag.Nws tsis muaj chloride ions, tsis nqus dej noo, thiab tsis corrode steel qauv.Magnesium chloride board yog acidic, thaum magnesium oxide sulfate board yog nruab nrab lossis tsis muaj zog alkaline, nrog tus nqi pH ntawm 7-8.
Thaum Lub Rau Hli 2018, Ministry of Industry thiab Information Technology tau tshaj tawm cov ntaub ntawv thiab cov cai los suav nrog Magnesium Oxide Sulfate Board nyob rau hauv qhov tseem ceeb los txhawb kev tsim cov khoom siv tiv thaiv ib puag ncig ntsuab ntsuab (daim Tshooj 43).Thaum Lub Kaum Hli 2020, peb lub chaw haujlwm tau suav nrog hauv daim ntawv teev cov khoom siv vaj tsev ntsuab.
Kev sib piv Cov lus ntawm Magnesium Oxide Sulfate Board thiab Magnesium Chloride Board
| Cov khoom sib piv | Magnesium Chloride Board | Magnesium Oxide Sulfate Board |
| Moisture absorption & tsos ntawm scumming phenomenon | Nws yog tsis yooj yim sua kom zam tag nrho cov tshwm sim ntawm noo noo nqus thiab cov tsos ntawm scumming tshwm sim los ntawm dawb chloride ions, uas yog twv yuav raug hu tshwm sim nyob rau hauv tej yam kub thiab av noo tej yam kev mob. | Tsis muaj cov tshuaj dawb chloride ions, tsis muaj cov tsos ntawm noo noo nqus thiab scumming |
| Kev puas tsuaj rau qhov chaw dai kom zoo nkauj tshwm sim los ntawm kev nqus dej noo & zoo li scumming | Nyob rau hauv ib qho chaw ntub dej, kev nqus dej noo thiab cov tsos ntawm cov scumming yuav ua rau muaj teeb meem loj xws li kev poob ntawm cov txheej, xim, wallpaper, blistering, fading, thiab hmoov. | Tsis muaj kev pheej hmoo zais ntawm kev puas tsuaj rau cov hniav zoo nkauj |
| Daim ntawv thov ib puag ncig txwv los ntawm kev nqus dej noo | Qhov kev txwv ntawm daim ntawv thov ib puag ncig yuav tsum yog qhov siab, yuav tsum tau siv rau hauv qhov chaw qhuav lossis ib puag ncig sab hauv tsev nrog qhov kub thiab txias tsis tu ncua | Tsis muaj qhov tshwj xeeb yuav tsum tau siv rau ib puag ncig, tuaj yeem siv dav hauv kev kho kom zoo nkauj sab hauv tsev thiab sab nraum zoov nyob rau hauv ntau yam kev nyab xeeb |
| Kev puas tsuaj rau lub rooj tsavxwm zoo & kev ua haujlwm los ntawm kev nqus dej noo | Rov ua dua cov dej noo los ntawm kev hloov pauv hauv huab cua thiab ib puag ncig yuav muaj kev cuam tshuam loj heev rau lub rooj tsavxwm lub zog, tawv, thiab kev pabcuam lub neej, nrog rau kev phom sij loj xws li tom qab deformation, tawg, thiab embrittlement. | Tsis muaj kev phom sij zoo, kev ua haujlwm ruaj khov |
| Corrosion ntawm steel qauv tshwm sim los ntawm dawb chloride ions | Dawb chloride ions tiag corrode steel qauv Cheebtsam, tsis tuaj yeem siv rau hauv ntau lub teeb thiab hnyav steel qauv vaj tse. | Tsis muaj cov tshuaj dawb chloride ions, tuaj yeem tiv thaiv cov qauv hlau los ntawm kev xeb los ntawm cov kua qaub thiab alkali sab nraud, tsis muaj kev nyab xeeb ntawm kev rhuav tshem cov qauv steel lub zog, tuaj yeem siv dav hauv ntau lub teeb thiab hnyav steel qauv vaj tsev. |
| Board zog | Siab | Siab |
| Board Toughness | Siab | Siab |
| Kev ua haujlwm ntawm dej tsis kam | Tsis zoo (tsis tuaj yeem siv rau hauv qhov chaw ntub dej) | High (tuaj yeem siv rau hauv qhov chaw ntub dej) |
| Kev txwv ntawm kev thov hauv kev tsim kho | Seb nws yog corrosive rau steel qauv yog qhov tseem ceeb | - |
| Kev lag luam thoob ntiaj teb zoo lub koob npe nrov | Feem ntau tsis zoo lub koob npe nrov hauv kev ua lag luam thoob ntiaj teb yog vim muaj cov ntsiab lus chloride ion siab ua rau cov dej nqus dej thiab cov teeb meem scumming. | - |
Lub ntsiab kev ntsuas ntsuas kom paub qhov txawv ntawm magnesium chloride board thiab magnesium oxide sulfate board yog cov ntsiab lus chloride ion.Raws li Intertek cov ntaub ntawv qhia txog kev ua haujlwm ntawm lub cev thiab tshuaj lom neeg ua los ntawm peb raws li Australian tus qauv, cov ntaub ntawv cov ntsiab lus chloride ion tsuas yog 0.0082%.
