3. Cov khoom ua haujlwm
Kev tiv thaiv corrosion
Cais cov yeeb nkab los ntawm corrosive media nyob rau hauv dej, oxygen, thiab av, tiv thaiv electrochemical corrosion nyob rau sab nrauv ntawm cov yeeb nkab hlau.
Extended Service Life
Qhov tseem ceeb txhim kho qhov kav ntev ntawm cov kav dej, txuas ntxiv nws lub neej tsim mus rau ntau dua 50 xyoo nyob rau hauv cov xwm txheej faus.
Adaptable rau ntau yam kev ua haujlwm
Haum rau cov dej hauv nroog, cov dej ntws, thiab cov kav dej faus dav dav dav dav, ua kom pom kev hloov tau zoo rau cov av sib txawv thiab dej ib puag ncig.
Kev tsim kho zoo sib xws:
Tau tshaj cov txheej txheem tsim khoom thiab kev teeb tsa ntawm cov kav hlau txuas, tsis muaj kev cuam tshuam rau kev thauj mus los, kev teeb tsa, lossis kev sib koom ua ke.
Material Configuration & ISO2531 Txheej Kev Zoo Zoo
Cov khoom siv txheej tau txais cov qib siab - zoo hloov asphalt ua raws li ISO2531 cov lus qhia txog kev ua haujlwm. Ua ntej txheej txheej, cov yeeb nkab sab nrauv yuav dhau los ntawm kev txhaj tshuaj blasting kev kho kom zoo kom tshem tawm cov nplais oxide, molding xuab zeb, xeb thiab cov kab mob, kom ntseeg tau cov qauv txaus thauj tog rau nkoj ruaj khov ntawm txheej thiab hlau puag. ISO2531 qhia txog qhov tsim nyog yam tsawg kawg nkaus qhuav zaj duab xis tuab kom lav tag nrho cov kev pab cuam yam tsis muaj substrate. Cov txheej asphalt tiav lawm nta dej zoo impermeability thiab ruaj khov tshuaj inertness tiv thaiv feem ntau nruab nrab av compositions. Tag nrho cov txheej txheem txheej tuaj yeem ua haujlwm tsis tu ncua ntawm cov kav dej ntau lawm, haum rau loj - ntim cov yeeb nkab thiab fittings batch kho. Piv nrog cov txheej txheem polyurethane siab heev, nws muab kev tiv thaiv kev lag luam tiv thaiv - kev xaiv corrosion rau cov khoom siv hauv nroog loj.
Kev tsim kho Standard & Environmental Adaptability
Txhua qhov kev npaj nto, txheej thickness, kho mob thiab tshuaj xyuas cov khoom yuav tsum ua raws li ISO2531 cov cai rau cov kav hlau kav hlau. Lub asphaltic txheej txheej yog tsim los rau faus installation ib puag ncig. Qhov ntsuas kub ntawm qhov chaw ua haujlwm nyob nruab nrab ntawm -20℃txog 60 degree, muaj peev xwm ua rau lub caij ntuj sov kub hloov pauv thiab ntev -lub sijhawm hauv av ntub dej. Cov txheej txheem txheej no yog pom zoo rau cov kav xa dej hauv thaj chaw nruab nrab lossis tsis muaj zog alkaline av. Rau cov cheeb tsam uas muaj cov av acidic heev lossis cov ntsiab lus hauv av chloride ion siab, ntxiv cov tshuaj tiv thaiv corrosion ntxiv xws li wrapping daim kab xev yuav tsum tau ntxiv. Tom qab txheej txheej solidification, kev soj ntsuam pom thiab kev ntsuas thickness yuav raug ua ib qho los ntawm ib qho los xyuas cov hlwv, tawg, tev thiab tsis sib luag ntawm qhov chaw nyias ua ntej cov kav dej tawm hauv lub hoobkas.
Kev tiv thaiv -Corrosion Mechanism & Kev Pabcuam Kev Ua Haujlwm Zoo
Asphaltic txheej ua tiav los tiv thaiv- cov nyhuv corrosion feem ntau los ntawm kev sib cais ntawm lub cev. Cov yeeb yaj kiab tsis tu ncua tiv thaiv dej hauv av, oxygen thiab corrosive ions los ntawm kev sib cuag ncaj qha rau cov hlau nplaum, txiav tawm cov tshuaj tiv thaiv electrochemical corrosion. Thaum kev tsim kho ua tau raws li ISO2531 specifications yam tsis muaj kev puas tsuaj thaum lub sij hawm thauj mus los thiab rov qab, nws tuaj yeem muab kev tiv thaiv sab nrauv rau ntau tshaj 20 xyoo nyob rau hauv ib puag ncig faus hauv nroog. Nws yuav tsum tau muab sau tseg tias asphalt txheej tsis tuaj yeem siv los ua cov txheej txheem sab hauv rau cov kav dej siv tau, tsuas yog txwv rau sab nrauv los tiv thaiv -corrosion. Nyuaj cuam tshuam, khawb hnyav thaum thauj khoom, thauj thiab trench backfill yuav rhuav tshem kev ncaj ncees ntawm txheej tiv thaiv, kev kho hauv zos yuav tsum tau ua thaum txheej txheej puas tshwm sim.
Matching Scope & Quality Inspection Rules
Qhov ISO2531 raws li asphalttic txheej no tuaj yeem siv rau sab nrauv ntawm txhua yam khoom siv hlau ua raws li ISO2531, suav nrog cov kav dej ncaj, khoov, tees, reducers thiab ntau yam flanged fittings. Cov neeg siv khoom tuaj yeem xaiv cov txheej txheem kub asphalt los yog asphalt primer ntxiv rau topcoat ob - txheej txheej raws li daim ntawv ntsuam xyuas av. Tag nrho cov kav dej coated tiav ua tiav cov qauv ntsuas ntsuas raws li ISO2531 kev soj ntsuam cov cai. Cov khoom tau muab nrog cov ntaub ntawv soj ntsuam kev kho saum npoo, yooj yim rau kev lees txais kev tsim hluav taws xob txawv teb chaws. Cov txheej txheem txheej txheem sib tw ua haujlwm ntau lawm, ruaj khov khoom rau thoob ntiaj teb cov dej xa mus rau cov kav dej.
