Ntxiv kua iav rau pob zeb ua: ib co nuances

Cov kua iav yog siv los ntawm cov neeg tsim khoom thaum tsim ntau lub tsev sib xyaw. Raws li txoj cai, nws muaj calcium silicates los yog potassium silicates. Tus nqi ntawm qhov no zoo ntawm ntau lawm ntaub ntawv yog tsis muaj, muab cov sodium silicate nyob rau hauv lub pob zeb, koj muaj peev xwm heev txhim khu nws zoo. Vim hais tias muaj cov silicates nyob hauv nws cov muaj pes tsawg leeg, nws tuaj yeem siv rau hauv cov khoom ntawm cov qauv siv hluav taws xob.

Koj ntxiv tau khob iav rau pob zeb txuas, ua raws li cov hauv qab no:

• Ua kom muaj zog ntawm cov khoom ya raws.
• Kev Txhim Kho ntawm kev ntxim siab antiseptic.
• Ntxiv refractoriness.

Nws yog siv hauv cov chaw hauv qab no

Kua iav yog dav siv nyob rau hauv lub foundry kev lag luam, tsis muaj nws yog tsis yooj yim sua los tsim ntawm xab npum thiab daim ntawv.

Yog hais tias peb tham txog kev tsim kho, ces qhov uas yuav siv tau yog qhov qis heev. Hauv particular, thaum ua kua iav ntxiv rau pob zeb ua ke, nws yuav siv los ua ib tus qauv zoo. Nyob rau hauv tus nqi mus txog ¼ ntxiv tau ntxiv rau lub pob zeb tsim kho kom zoo dua qub. Yog li, nrog kev nce hauv dej tsis kam, nws ntxiv rau hauv ib qho nyiaj ntawm 15%, yuav kom nce refractory qualities, nws yuav tsum ntxiv 25%. Nrog tib lub hom phiaj, cov neeg ua haujlwm ua kom tsis tuaj yeem kho cov qauv no nrog cov qauv ntoo.

Feem ntau cov justified mus ntxiv dej iav nyob rau hauv lub pob zeb ua thaum lub sij hawm installation ntawm lub hauv paus los cov vaj tse nyob rau hauv ntub lowlands, nyob rau hauv qhov chaw nrog ib tug high school cov sawv hauv av dej, nrog lub hom phiaj ntawm kev tsim kho ntawm hydraulic lug, raws li zoo raws li nyob rau hauv kev tsim kho ntawm boilers, furnaces thiab fireplaces. Lub hauv paus nrog xws li ib tug additive tsis tsuas yog tiv thaiv lub tsev los ntawm noo noo, tab sis tsis xav tau kev kho ntxiv nrog antiseptics.

Qhov no yog li cas cov ntsiab lus silica thiab aluminosilicate tau npaj tseg. Nyob rau hauv txoj cai, yog tias muaj cov vaj tse txaus thiab tsawg kawg hauv tsev thiab kev siv khoom, nws yog qhov ua tau rau lawv noj txawm nyob hauv tsev.

Nws yog tsim nyog yuav tsum paub raws nraim cov kev mob rau kev npaj ntawm cov qauv qhob thiab cov khoom ntawm nws cov hom qhob. Yog li, thaum siv lub hom M200 thiab saum toj no, 72 liters ntawm lub khob iav yuav tsum muab ntxiv rau ib lub voos xwmfab ntawm cov tshuaj tiav. Qhov voltage ntawm cov sib tov ntawm no piv yog qhov feem ntau pom. Txawm li cas los xij, nyob hauv kev pib ua kom zoo ntawm cov khoom zoo li no tsis tas yuav, thiab yog li ntawd nws muaj cai pub ntxiv rau cov khob iav rau lub pob zeb, nqa qhov piv rau 1: 10. Yog li ntawd koj tuaj yeem txuag nyiaj ntau.

Xav seb yuav ua li cas qhov composition yog npaj rau waterproofing:

• Khob ntxiv xwb nyob rau hauv lub pob zeb sib tov, siv 10 liv ntawm nws ib liter iav.
• Cov lus muaj pes tsawg leeg yuav tsum siv rau 5-7 feeb xwb!

Ua ke nrog pob zeb, qhov no muaj pes tsawg leeg ua ib qho tuab thiab sib zog ceev sib xyaw. Nws yog ib qho ua tau los nrhiav ob peb yam yooj yim ntawm qhov teeb meem no. Yog hais tias tsis zoo los ntawm cov tshuaj tsis tsim nyog, koj tuaj yeem dilute nrog dej, tab sis cov qhov dej tsis tau yog li ntawd. Tseem, nws yog qhov tsim nyog ntxiv rau cov khob iav los ua vaj tse, npaj rau hauv cov khoom me me. Nyob rau hauv cov ntaub ntawv ntawm qhov zoo ua tshuaj khib foundation yuav muaj yav tom ntej kev qualities.
