Kua iav feem ntau yog siv los ntawm cov neeg tsim khoom hauv kev npaj ntau lub tsev sib xyaw. Raws li txoj cai, nws muaj silicates ntawm calcium los yog potassium. Tus nqi tsim khoom ntawm cov ntaub ntawv no tsawg, tab sis los ntawm kev ntxiv cov iav ua kua rau hauv pob zeb, koj ua kom nws zoo dua. Muab lub xub ntiag ntawm silicates nyob rau hauv nws muaj pes tsawg leeg, nws yuav siv tau nyob rau hauv zus tau tej cov refractory lug.
Koj tuaj yeem ntxiv cov iav ua rau pob zeb rau cov laj thawj hauv qab no:
- Strengthening moisturizing zog.
- Txhim kho cov tshuaj tua kab mob zoo.
- Txhim kho hluav taws kub.
Nws yog siv rau hauv qab no
Cov iav ua kua yog siv dav hauv kev lag luam foundry, tsis muaj nws tsis tuaj yeem tsim cov xab npum thiab ntawv.
Yog tias peb tham txog kev tsim kho, ces qhov kev siv tau nqaim dua. Tshwj xeeb, thaum cov iav dej ntxiv rau hauv pob zeb, nws tuaj yeem siv los ua cov primer zoo. Txog li ¼ tuaj yeem ntxiv rau lub tsev pob zeb los txhim kho nws qhov zoo. Yog, ntawmtxhawm rau ua kom cov dej tsis kam, nws yog ntxiv rau qhov nyiaj ntawm 15%, txhawm rau txhim kho cov khoom zoo, nws yuav tsum tau ntxiv 25%. Rau tib lub hom phiaj, builders impregnate ntoo lug nrog no compound.
Nws yog qhov tsim nyog tshaj plaws los ntxiv cov iav ua kua rau hauv pob zeb thaum txhim kho lub hauv paus pads ntawm cov tsev nyob hauv qhov chaw ntub dej, nyob rau hauv qhov chaw siab ntawm cov dej hauv av, txhawm rau tsim cov qauv hydraulic, nrog rau kev tsim kho. chav boiler, furnaces thiab qhov cub. Lub hauv paus nrog xws li ib tug additive tsis tsuas yog zoo kawg nkaus tiv thaiv lub tsev los ntawm ya raws, tab sis kuj tsis xav tau kev kho mob ntxiv nrog antiseptics.
Qhov no yog li cas silica thiab aluminosilicate foundations tau npaj. Raws li txoj cai, nrog rau cov tsev tsim nyog thiab tsawg kawg nkaus kev tsim kho thiab cov khoom siv, nws muaj peev xwm ua noj rau lawv txawm nyob hauv tsev.
Nws yog ib qho tsim nyog yuav tsum paub meej cov xwm txheej rau kev npaj cov txheej txheem pob zeb thiab cov khoom ntawm nws lub npe tshwj xeeb. Yog li, thaum siv M200 hom thiab siab dua, 72 litres ntawm cov iav kua yuav tsum tau ntxiv rau ib lub voos xwmfab ntawm cov tshuaj tiav. Qhov nro ntawm qhov sib tov ntawm qhov piv no yog qhov zoo tshaj plaws. Txawm li cas los xij, hauv kev tsim kho cov neeg nyiam ua haujlwm zoo li no tsis tas yuav tsum tau ua los ntawm cov qauv, thiab yog li nws yog qhov txaus los ntxiv cov iav ua rau pob zeb, nqa cov proportions rau 1: 10. Qhov no koj tuaj yeem txuag tau nyiaj ntau.
Cia peb xav txog yuav ua li cas cov txheej txheem rau kev tiv thaiv dej yog npaj:
- iav tsuas yog ntxiv rau qhov sib xyaw ua ke, siv ib liter rau 10 litres ntawm nwsiav.
- Kev sib xyaw yuav tsum siv li ntawm 5-7 feeb nkaus xwb!
Ua ke nrog cov pob zeb ua ke, cov khoom sib xyaw no tsim cov sib xyaw tuab thiab nrawm nrawm. Nws muaj peev xwm nrhiav tau ob peb txoj hauv kev yooj yim tawm ntawm qhov xwm txheej no. Yog tias qhov zoo tshaj plaws tsis xav tau los ntawm kev daws teeb meem, koj tuaj yeem dilute nws nrog dej, tab sis cov waterproofing yog li ntawd. Tseem, nws yog qhov tseeb dua los ntxiv cov iav ua kua rau hauv pob zeb, npaj rau hauv me me. Nyob rau hauv cov ntaub ntawv ntawm ib tug zoo mortar, lub hauv paus yuav muaj zoo heev technical qualities.
