Pob zeb vov tsev vuas yog ib qho ntawm cov khoom siv vov tsev nrov tshaj plaws rau ntau pua xyoo vim lawv qhov kev zoo nkauj tsis sib xws thiab ua haujlwm ntev. Ua ntej qhov kev tshwm sim ntawm cov cuab yeej siv niaj hnub no, cov vuas no feem ntau yog ua los ntawm tes lossis ib nrab ntawm cov tshuab ua haujlwm. Tam sim no, cov txheej txheem tau hloov mus rau hauv txoj kev siv tshuab zoo, ua kom cov pob zeb ua pob zeb tsim cov nroj tsuag kom tau raws li qhov xav tau ntawm kev tsim kho kev lag luam.
Cov txheej txheem tsim cov pob zeb vov tsev pib nrog kev sib txuas ntawm plaub yam khoom ntuj: xuab zeb, cement, dej thiab hlau oxide. Cov khoom xyaw ntuj no yuav dhau los ntawm kev sim ntau yam kom ntseeg tau tias lawv ua tau raws li cov qauv tsim nyog. Thaum tsim nyog, cov xim yog ntxiv rau qhov sib tov nrog rau ntau yam additives. Qhov sib tov yog ces nias rau hauv cov ntaub ntawv steel los tsim cov pob zeb cib ntawm cov duab uas xav tau. Cov pwm no niaj hnub tshuaj xyuas thiab ntxuav los ntawm pab pawg tswj xyuas kom zoo los tiv thaiv cov xuab zeb, cement thiab sealants los ntawm kev tsim nyob rau hauv cov kab nrib pleb, uas tuaj yeem ua rau cov vuas warp.
Cov vuas tom qab ntawd muab tso rau ntawm racks thiab coj mus rau qhov cub kom qhuav qhov twg lawv yuav zaum li plaub teev. Tom qab cov vuas tau hardened, tshem tawm lawv los ntawm lub khib thiab siv lub tsho tiv no ntawm dej-raws li masonry sealer. Cov sealer no yog siv rau cov nplais pobzeb los tiv thaiv huab cua. Cov vuas xaiv raug rub los ntawm cov kab ntau lawm txhua teev rau kev kuaj xyuas lub zog kom ntseeg tau tias cov vuas ua tau raws li lossis tshaj qhov tsawg kawg nkaus cov qauv teev tseg los ntawm cov cai rau kev tawg lub zog ntawm 300 PSI, lossis phaus ib square inch.
Thaum kawg, cov vuas yog stacked thiab bundled rau hauv pallets. Txhua lub pallet suav nrog kwv yees li 300 square feet ntawm lub ru tsev. Tam sim no cov pallets npaj tau muab tso rau hauv cov khoom muag rau kev txiav txim yav tom ntej, lossis xa mus rau qhov chaw ua haujlwm qhov chaw lawv yuav raug teeb tsa thiab khaws cia rau xyoo tom ntej.
Txawm hais tias cov txheej txheem tsim khoom rau cov vuas vov tsev tau hloov pauv raws sijhawm, tam sim no tsim ntau ntau qhov kev hloov pauv hauv cov duab thiab xim, qhov kev zoo nkauj tsis tu ncua thiab kev ruaj khov.
