Cov txheej txheem ua haujlwm ua lub luag haujlwm tseem ceeb hauv kev tswj hwm ntawm kev tsim kho cov phiaj xwm. Lub smoothness thiab flatness ntawm cov formwork nto ncaj qha cuam tshuam rau cov tiaj ntawm cov pob zeb ua. Yog li ntawd, kev tsim tawm ua qauv yuav tsum ua raws cov txheej txheem nruj, txhim kho ntau lawm tshuab ua haujlwm npaj, gluing, kub nias, thiab trimming. Cov txheej txheem ntau lawm yog raws li hauv qab no:
1. Cov ntaub ntawv nyoos Tej: Cov ntaub ntawv raw yog tau los ntawm txheej cav. Cov cav tau yog kab rov tav txiav thiab teb - Txiav rau ib txheej txheej tuab. Cov cav yog tom qab ntawd txiav rau hauv cov txheej txheem sib npaug raws li qhov loj me ntawm cov formwork. Impurities nyob rau saum npoo ntawm cov txheej ntoo tau muab tshem tawm, raws li cov no tuaj yeem cuam tshuam cov nplaum ntawm cov kua nplaum tom qab.
2. Kom qhuav thiab kev ua kom qhuav: cov txheej ntoo tom qab txiav thiab teb -}}}} kev txiav muaj cov ntsiab lus noo noo. Yog li ntawd, rau loj {{3} teev ntau lawm, peb siv lub tshuab kom qhuav tshuab kom qhuav. Cov txheej ntoo qhuav yog qhov tawg paj, yog li lawv yuav tsum tau sab laug kom sawv ntsug ib txwm rau 2 {{} 3 hnub los xyuas kom meej lawv cov tawv. Hauv cov khoom siv me me-teev, lub hnub kom qhuav yuav siv tau.
3. Cov ntaub ntawv tso tawm thiab txheej txheem txheej txheem txheej txheem tsim qauv: Ib qho kev siv vaj huam sib luag ua tiav tau muaj ntau txheej ntoo ntoo sib koom ua ke siv cov txheej txheem daim nplaum. Cov kua nplaum tshwj xeeb yog siv los siv cov kua nplaum arely rau ob sab ntawm cov ntoo ntoo los ntawm cov neeg thov khoom ntoo. Tom qab ntawd cov ntoo glued ntoo yog tom qab ntawd muab tso rau ntawm daim formwork nto, thiab 6-10 txheej tau thov tusyees (raws li xav tau).
4. Cov xovxwm kub: Tom qab cov txheej txheem flued formwork yog nteg, lawv tau pluav siv cov txheej txheem kub kub. Tsoos cua sov siv cov qauv siv boiler rau cov cua sov; Cov cuab yeej siv hluav taws xob niaj hnub no siv hluav taws xob cua sov. Nto ua kom muaj zog ntxiv rau qhov ceev ntawm cov formwork, ua rau muaj kev coj ua ntau dua thiab txhim kho zoo. Lub pre -} Nias ua raws li kev nias siab thiab kub thiab txias thaum txhua daim ntawm cov kev siv kub ua kom zoo thiab hardness.
5. Kev tha xim, txiav, thiab ntim khoom siv: tom qab siv kub ntawm cov formwork yuav ua kev tsis zoo thiab cov npoo tsis tu ncua. Cov khoom siv dhau heev yog txiav nrog carving riam, thiab tom qab ntawd coated nrog anti- corrosion xim. Cov xim no yog qhov tseem ceeb heev rau kev ua kom muaj lub neej thiab lub sijhawm ntim ntawm cov formwork. Cov formwork yog lub teeb ci, muaj cov thawv siab {{5 6} boot {} packaged, muaj corrosion {{{tiv taus.
