Nyob rau hauv ntau zaus, lub sij hawm sib cuag ntawm txhuas thiab tshiab pob zeb luv luv, yog li nws feem ntau tsis ua teeb meem. Ua ntej, ib qho tseem ceeb corrosion ntawm txhuas embedded nyob rau hauv pob zeb ua tau tshwm sim. Qhov corrosion tau ua rau expansion ntawm lub pob zeb thiab tom qab tawg ntawm hardened pob zeb.
Tsis tas li ntawd, koj yuav ua li cas tiv thaiv aluminium ntawm pob zeb?
Tiv thaiv Aluminium Ncej hauv Masonry Phab Ntsa
- Xaiv cov coatings rau kev tiv thaiv siab pH.
- Muab aluminium thav duab rau hauv phab ntsa tom qab mortar tau kho.
- Sib cais thav duab thiab masonry nrog ib tug caulk qhov sib txawv.
- Tshem tawm cov mortar tshiab los ntawm aluminium thav duab kom sai li sai tau.
- Direct dej deb ntawm phab ntsa nrog drips thiab flashings.
Tsis tas li, dab tsi tiv thaiv electrolysis ntawm hlau thiab txhuas? Galvanic corrosion tuaj yeem tiv thaiv los ntawm ntau txoj hauv kev:
- Xaiv cov hlau / alloys kom ze li sai tau hauv cov galvanic series.
- Tsis txhob cuam tshuam thaj tsam ntawm ib qho me me anode thiab cathode loj.
- Insulate cov hlau tsis sib xws nyob qhov twg los tau.
- Siv cov coatings nrog ceev faj.
Tom qab ntawd, ib tug kuj yuav nug, puas pob zeb ua pob zeb?
Tus yuam sij kom ua tau zoo pouring pob zeb tshaj qhov uas twb muaj lawm pob zeb nto yog los xyuas kom meej ob txheej daim ntawv cog lus kom zoo. Txawm yog pob zeb muaj zog thiab tsim cov qauv nyuaj, tsis muaj dab tsi hauv nws uas pab nws stick mus laus pob zeb . Ib tus neeg sawv cev ua lag luam sib koom ua ke pab nrog qhov ntawd.
Puas yog rebar corrode hauv pob zeb?
Vim yog pob zeb ua kev tiv thaiv ntawm tus kheej, reinforcing steel ua tsis yog xeb nyob rau hauv feem ntau ntawm pob zeb cov khoom thiab cov qauv. Txawm li cas los xij, corrosion tuaj yeem tshwm sim thaum txheej txheej passive raug rhuav tshem.
