Los ntawm kev tshem tawm kev puas tsuaj ntawm chloride, cov thawv nyias tau siv Magnesium Sulfate (MgSO4) los replace Magnesium Chloride. Feem ntau hu ua Sulfate MgO Board.
Cov cim tseem ceeb: Nws muaj qhov zoo ntawm kev tsaus paub rau tsoo thiab tsis muaj chloride.
Qhov zoo tshaj plaws: Tsiaj tsis puas tsuaj. Nws tsis cuam tshuam rau cov ntaub steel lossis cov khoom siv hluav taws xob los ua qhov puas tsuaj, thiab nws tsis "tso dej" lossis tso dej los ntawm nws thaum muaj qhov dej ntau.
Qhov zoo ntawm kev nyob zoo: Nws nyob zoo dua thaum muaj dej thiab feem ntau muaj lub neej nyob siab dua rau kev siv hauv kev kho tshiab.
Txais rau daim ntawv tswj hwm Class A1 uas tsis kub. Nws tsis muaj kub tshuab thiab tsis muaj duab kub tshuab uas tsis zoo rau kev noj qab, txhawb cov phooj ywg rau koj lub tsev.
Muaj kev txaus los kub thiab dej txaus los kub. Nws pab tshem tshuaj kub thiab dej tshuab, thiab tshem tshuaj kub thiab tshuaj kub uas tuaj yeem tshuab rau hauv qhov chaw uas muaj dej siab lossis hauv qhov chaw uas muaj dej siab heev.
Qhov no yog ua los ntawm cov khoom uas muaj hauv ntiaj teb thiab tsis muaj tshuaj kub (tsis muaj formaldehyde). Qhov kub siab ntawm no yog li qhov kub siab ntawm cov khoom siv tsev uas muaj nyob rau hauv lub ntiaj teb, yog li no yog qhov khoom siv tsev uas muaj kev siv tau ntev.
Muaj kev nyab xeeb thiab txaus los kub heev. Nws tuaj yeem txaus los kub rau hauv qhov chaw uas muaj kub siab thiab kub siab, yog li nws pab tshem qhov siv tau ntev ntawm lub tsev thiab tshem qhov siv tau ntev ntawm kev siv tau ntev.
Yeej tshaj li ntau thiab yooj yim rau kev kho, tawg, thiab tso. Nws yog qhov tseem ceeb rau cov kev sib txuas ntawm lub tsev uas muaj peev xwm nyob hauv lub tsev, xws li cov khoom siv rau kev sib txuas ntawm cov dej tsis zoo thiab cov dej ntawv, uas txo qhov teeb meem ntawm kev sib txuas thiab kev siv tswv yim.
Raws li qhov ntau ntawm nws thiab qhov ua tau zoo, nws muaj kev khaub ncaws txhawb kev hlub tswv yim zoo heev. Nws txo qhov kev sib txuas ntawm kev hlub tswv yim rau hauv lub tsev lossis los ntawm qhov ncaj qha, uas ua rau lub tsev yuav muaj kev hlub tswv yim zoo thiab yuav nyob zoo dua.
Ob qhov khoom no yog qhov chaw sib txuas ntawm Tsis yog peb qab ntxhais (uas tseem hu ua MgO Boards thiab Magnesia Boards tib yam li cas, lawv cov lus qhia cheemical thiab lawv cov cim ntawm kev ua haujlwm—yeej tshwj xeeb rau qhov dej—tsis sib xws.
