Kev tsim kho ntawm cov cement mortar nyob rau hauv ob txoj kev.Thawj pem teb centrifugation.Feem ntau haum rau cov kav dej nrog kev tsim kho DN400 caliber lossis tsawg dua.Tab sis underground spraying, feem ntau yog siv rau DN700 txoj kab uas hla pipeline corrosion tsim saum av.

Cement mortar yeeb nkab corrosion: sib tov ntawm cov cement, xuab zeb thiab dej, hu ua cement mortar.Feem ntau hu ua 1: 3 cement mortar nrog 1 feem cement thiab 3 seem xuab zeb nrog, qhov tseeb, tsis quav ntsej cov dej muaj pes tsawg leeg, feem ntau yog nyob rau hauv qhov sib piv ntawm 0.6, uas yuav tsum yog 0.6: 1: 3 cement mortar siv hauv kev tsim kho. tej yaam num nyob rau hauv, thawj lub hauv paus thiab phab ntsa masonry, masonry thaiv siv los ua cov khoom nplaum, xws li masonry rubble, liab cib siv cov cement mortar;qhov thib ob yog siv rau sab hauv thiab sab nrauv plastering.Cement mortar thaum siv, lawv feem ntau suav nrog cov khoom siv ntxiv xws li micro-foaming tus neeg saib xyuas, cov hmoov dej tsis zoo los txhim kho nws cov haujlwm ua haujlwm thiab viscosity.Cement mortar hauv kev faib ua feem koom nrog lub pob zeb, lawv ua pob zeb.Qib cement mortar lub zog yog txhais los ntawm cov qauv txheej txheem rau kev tsim khoom thiab kev saib xyuas ntawm lub voos xwmfab, hauv 28d hnub nyoog, tus nqi ntsuas los ntawm Standard Test Method rau Compressive Strength ntawm tag nrho cov kev faib tawm.Nyob rau hauv cov cuab yeej muaj xws li cov hlau txhaj tshuaj blasting tshuab, peb PE winding khoom, PE yeeb nkab dub thiab daj tsho rub cov cav tov, xuab zeb-blasting khoom, polyurethane Low Fat Kee, ua npuas ncauj platform, FRP winding tshuab, ob txheej PE, cement corrosion insulation mortar spraying. cov cav tov thiab lwm yam khoom siv ntsuas ntsuas.Lub tuam txhab tuaj yeem lees txais ib leeg thiab ob chav steel yeeb nkab fusion bonded epoxy hmoov (FBE), ob chav polyethylene (2PE) thiab peb polyethylene (3PE), ob chav polypropylene (2PP), thiab peb poly propylene (3PP), thee tar epoxy yeeb nkab txheej, polyurethane prefabricated faus yeeb nkab rwb thaiv tsev, dub thiab daj tsho yeeb nkab rwb thaiv tsev, IPN8710 corrosion anti-corrosion txheej polymer, epoxy yeeb nkab corrosion, high-density polyethylene yeeb nkab corrosion, corrosion ntawm cement mortar hauv ob sab phlu, prefabricated faus yeeb nkab rwb thaiv tsev corrosion thiab lwm yam dej num.

Cement mortar hauv ob sab phlu Kev ua tau zoo: Vim yog cov yeeb nkab steel ntim nrog cov pob zeb, tuaj yeem nqus tau ntau ntawm cov cua sov, yog li cov hlua seem thaum raug hluav taws kub qhov chaw faib khoom tsis sib xws, ua rau tus ncej ntawm hluav taws-resistant, qeeb cua sov ntawm steel kab, thiab ib zaug yielding steel kab, pob zeb muaj peev xwm tiv taus feem ntau ntawm cov axial load, los tiv thaiv cov qauv kev sib tsoo.Qhov hluav taws kub tsis kam ntawm cov kab hluav taws xob sib xyaw yuav nce ntxiv raws li qhov kub ntawm cov nqaj hlau los ntawm cov flange sab saum toj ntawm cov cua sov yuav raug xa mus rau cov pob zeb nce.Cov kev tshawb fawb soj ntsuam qhia: mus txog 3 teev hluav taws kub tiv thaiv qib yuav tsum tau txais kev cawmdim thiab muab piv nrog hluav taws kub retardant txheej steel kab 1/3 a 2/3 los yog ntau tshaj, nrog rau cov yeeb nkab txoj kab uas hla nce, txuag cov xim ntau dua.
