Qee qhov kub yaj nplaum nplaum muaj qee qhov teeb meem tom qab siv lawv ntev.
Ua ntej, cov nplaum nplaum kub yog tsis nplaum:
1. Kub yaj nplaum nplaum, yog tias muaj deterioration ua ntej ntau lawm. Kev ua haujlwm tsis zoo, khaws cia rau lub sijhawm ntev, yooj yim los tsim cov kev hloov pauv zoo, uas yuav cuam tshuam rau kev ua haujlwm ntawm kub yaj nplaum nplaum tsis ruaj khov kub yaj nplaum.
2. Kev ua haujlwm ntawm cov nplaum kub yaj. Vim tias tsis txaus permeability uas yuav cuam tshuam rau kev sib txuas ntawm pawg, qhov xwm txheej thiab kev ua haujlwm ntawm cov nplaum nplaum kub yog qhov ruaj khov thaum pib, tab sis dhau sijhawm, tej zaum yuav muaj nplooj poob, tawg ntawm kev sib txuas, thiab lwm yam.
3. Piv txwv li, qhov teeb meem ntawm nplooj poob, uas tsis tas yuav tshwm sim los ntawm kev ua haujlwm ntawm cov nplaum nplaum kub. Ua ntej gluing, nws yog ib qho tsim nyog los txiav txim siab seb qhov kub yaj nplaum puas nkag mus rau saum npoo ntawm cov ntawv thiab cov ntawv xov xwm zoo.
Qhov thib ob, qhov kub yaj nplaum nplaum tsis tuaj yeem raug tshem tawm nrog cov kua nplaum:
1. Ua ntej siv cov nplaum nplaum kub, nws puas tsis tau preheated rau ib lub sijhawm? (** Siv txhua hnub kub yaj kua nplaum phom, kub yaj kua nplaum phom, yuav tsum tau sov so hauv 4-6 feeb.))
2. Kub yaj nplaum nplaum yog ib qho yooj yim siv thiab khaws cia, tab sis kuj muaj lub neej txee. Feem ntau, lub txee lub neej ntawm cov nplaum nplaum kub yog 1 mus rau 1.5 xyoo, yog li xyuas seb lub txee lub neej ntawm cov nplaum nplaum kub tau tas sijhawm.
