Cement mortar lining anti-corrosion steel yeeb nkab hais txog kev kho corrosion resistant ntawm cov cement mortar hauv cov yeeb nkab steel hauv tubular lub cev.Lined nrog cov cement mortar hauv ob sab phlu los tiv thaiv corrosion steel yeeb nkab, steel yeeb nkab uas muaj cov pob zeb, uas tuaj yeem nqus tau ntau ntawm cov cua sov, thiab yog li raug kev txom nyem hluav taws kub qhov hluav taws kub qhov chaw faib khoom tsis sib xws, lub sij hawm ntawm qhov hluav taws kub tsis kam ntawm cov ncej, qeeb qeeb. Cov cua kub ntawm cov kab hlau, thiab ib zaug cov kab hlau tawm los ua vaj tse tuaj yeem tiv taus feem ntau ntawm cov axial load los tiv thaiv kev sib tsoo.Ntawm qhov hluav taws kub tsis kam ntawm cov kab hluav taws xob sib xyaw kuj tseem yuav nce ntxiv, vim tias qhov qis dua ntawm cov kab hluav taws xob steel yuav hloov cov cua sov ntawm sab saum toj flange mus rau cov pob zeb.
Cement mortar hauv ob sab phlu ntawm cov yeeb nkab phab ntsa thiab cov dej los yog roj cais tawm, tsim cov txheej txheem tiv thaiv kom tsis txhob muaj oxidation thiab corrosion ntawm cov yeeb nkab phab ntsa los ntawm lub raj mis fouling.Piv nrog rau lwm cov tshuaj tiv thaiv corrosion, cement mortar thiab cohesive quab yuam ntawm cov yeeb nkab phab ntsa, vim hais tias lub hydration ntawm cov cement hais los ua ib tug gel, lub puab phab ntsa ntawm cov yeeb nkab steel cemented quab yuam;ntim shrinkage ntawm cement mortar induration ze rau steel yeeb nkab Lub koom haum, tsim kev sib txhuam;ib tug neeg kho tshuab tom kev koom tes ntawm cov yeeb nkab steel sab hauv phab ntsa tsis sib xws, nrog cov cement mortar.
Cement mortar nyob rau hauv anticorrosion pipeline txheej txheem:
Kev sib xyaw ntawm cov cement, xuab zeb thiab dej yog hu ua cement mortar.1: 3 cement mortar feem ntau raug xa mus ua ke nrog ib feem ntawm cov cement thiab 3 seem xuab zeb, zoo li tsis quav ntsej cov dej muaj pes tsawg leeg, feem ntau nyob rau hauv qhov sib piv ntawm 0.6, uas yuav tsum dhau los ua ib qho ntawm 0.6: 1: 3 cement mortar lub hom phiaj hauv Kev tsim kho Engineering, Ua ntej, lub hauv paus thiab cov phab ntsa masonry, siv los ua cov ntaub ntawv ntawm cov khoom siv masonry loj, xws li cov pob zeb tawg, cov cib liab siv cov cement mortar;rau sab hauv tsev thiab sab nraum zoov plastering.Cement mortar thaum siv, tab sis kuj feem ntau suav nrog qee cov khoom siv ntxiv, xws li micro-foaming agents, dej hmoov los txhim kho nws txoj haujlwm thiab viscosity.Ntxiv qhov kev faib ua feem ntawm gravel, cement mortar los ua pob zeb.
