Thaum xaiv cov ntaub ntawv raw ntawm hollow block tshuab , peb kuj yuav tsum them sai sai rau qee yam teeb meem, uas yog, kev xaiv ntawm cov ntaub ntawv raw rau hollow block kuj muaj qee qhov kev tiv thaiv. Yog tias muaj teeb meem hauv kev xaiv ntawm raw cov ntaub ntawv, nws tseem yuav ua rau kev tiv thaiv ib puag ncig ntawm cov hollow cib, thiab cuam tshuam rau peb cov kev siv tom qab.
Hauv qee yam, qee cov ntaub ntawv pov tseg, nrog rau qee cov pa tshuaj tsis tuaj yeem siv vim tias lawv xeb, vim tias cov no yuav ua kev puas tsuaj rau tib neeg lub cev, thiab zoo li yuav tso tawm ntau cov pa phem thaum lub sijhawm siv.
Hauv cov ntawv, qee cov ntaub ntawv nyoos tau sib xyaw nrog lwm cov ntaub ntawv thaum lub sijhawm sib tov, thiab lwm yam tshuaj lom yuav tsim. Cov no yog qhov yuav tsum tau ua rau cov tshuab ua lub tsev rau hollow cib. Lwm yam chemical ua tuaj yeem tsim kev puas tsuaj rau lub tshuab, yog li peb yuav tsum xaiv raws li cov kev ceev faj ntawm cov khoom. Yog li kom ntseeg tau tus smoothness ntawm hollow cib tshuab cov txheej txheem ntau lawm, kev tsim khoom siv hollow cib ua raws li tus txheej txheem.
Nws tsis tsuas yog muab peb nrog ntau lub zog hollow cib, tab sis kuj nqa rov qab ntau dua rau cov tub ua lag luam. Tom qab ntawd peb txhua tus paub tias cov hollow cib ntau lawm cov txheej txheem tsuas yog tso siab rau kev nias ntawm cov khoom siv hydraulic, thiab cov ntaub ntawv raw yuav tsum sib xyaw thiab nplawm ua ntej molding. Nws yog ib qho tseem ceeb uas yuav tsum ua qhov sib piv uas tsim nyog kom nws thiaj li ua tau cov khoom lag luam zoo heev.
