Tam sim no, muaj ntau hom kev siv ub no thiab siv cov iav khoom siv: raws li casting flux, kev hloov thiab kev siv, lub tshuab ua kom sov dua, khoom siv raw thiab rov qab siv, thiab lwm yam.
1. Ua raws li lub plhaw rau hauv lub hnab
Cov nplaum iav siv tau ua ib qho dej rau lub pob zeb tawg ntawm hlau thiab pov npoo tooj hlau los npog cov tawv thiab tiv thaiv oxidation.
2. Kev Siv Tawm Sab Nraud
Kev siv cov txheej txheem yog ib hom kev ua dua tshiab uas yuav tsum tau tsim kho sai. Nyob rau hauv lub neej yav tom ntej, yuav muaj ntau yam yees tshiab uas tuaj yeem coj ntxiv rau kev hloov thiab siv. Tom qab lub iav tawg uas ua rau cov iav tawg tas ua tiav, nws yuav siv ntau lub hom phiaj raws li nram no:
(1) Siv cov khib nyiab iav los ua ke ntawm txoj kev pavement hauv Tebchaws Meskas thiab Canada tau ntau xyoo. Nws tau raug pov thawj tias siv cov iav khib nyiab li txoj kev muab tub lim yuav txo qhov kev huam yuaj ntawm lub tsheb tom qab siv dua lwm qhov khoom siv; qhov kev xav ntawm lub teeb yog tsim nyog; txoj kev pavement yog kev hnav zoo thiab tsim kua muag; qhov daus yaj sai sai thiab tsim nyog rau cov chaw tsis muaj kub. Siv thiab ua rau me ntsis.
(2) Muab cov iav crushed nrog cov ntaub ntawv tsim los ua lub tsev ua qhov chaw, cov bricks thiab lwm cov khoom siv hauv tsev. Xyaum tau ua pov thawj tias qhov loj thiab qhov muaj zog ntawm cov khoom tsim los ntawm kev siab nrog cov organic teeb meem raws li phau ntawv cog lus siab dua thiab cov nqi ntawm cov nqi qis dua.
(3) Lub iav uas tawg tau siv los ua kom zoo nkauj ntawm cov vaj tse, cov ntaub ntawv khoom vaj khoom tsev, kev kos duab thiab cov khoom siv tes ua thiab cov khaub ncaws accessories, uas muaj kev pom zoo nkauj zoo nkauj.
(4) Cov khob thiab cov khoom siv pov tseg cov khoom ua rau sib xyaw yuav ua rau cov khoom siv hluavtaws.
3. Cov iav uas txum ua rov ua dua qub dua thiab rov qab ua kom rov qab ua cov khob iav thiab fiberglass.
4. Daim iav tawg uas siv tawg ua dua qub yuav muab siv ua cov khoom siv iav hauv qhov ub khoom ntawm cov khoom siv raw, vim hais tias qhov tsim nyog ntawm cov iav tawg yuav pab tau iav kom yaj thaum kub dua.
5. Tam sim no, qhov rov qab siv cov iav ntim cov iav ntim khoom yog cov khoom tsim cov iav fwj nrog cov uas tsis muaj nqi thiab ntau heev. Xws li npias, dej qab zib fwj, kua ntses fwj, kua txiv hmab txiv ntoo thiab qee cov kaus poom ntim.
