Hauv kev tu vaj tse engineering, xaiv cov khoom siv grouting ncaj qha cuam tshuam rau kev kho kom zoo thiab kev pabcuam lub neej.Polyurethane rigid foam raw khoom rau txoj kev groutingtab tom hloov cov tsoos cement thiab asphalt-raws li grouts vim lawvtechnical thiab economic zoo.
Cov khoom siv niaj hnub grouting feem ntau raug kev txom nyem los ntawmqeeb curing, shrinkage, dej rhiab heev, thiab tsis zoo nkag mus. Piv txwv li,polyurethane ua npuas ncauj grouting raw khoomnthuav tawmqis pib viscosity, tso cai rau lawv nkag mus rau micro- tawg thiab nplua voids hauv qab pavements ua ntej nthuav dav.
Cov txiaj ntsig tseem ceeb ntawm polyurethane rigid foam grouting cov ntaub ntawv suav nrog:
Ua npuas ncauj expansion thiab solidificationhauv feeb
Lub teeb yuag tab sis siab - lub zog muaj zog, txo cov load ntxiv ntawm subgrade
Zoo heev adhesionrau pob zeb, asphalt, av, thiab pob zeb
Ntev - lub sij hawm durabilitynyob rau hauv qhov kub thiab txias thiab kev vibration
Peb txoj kev grouting PU ua npuas ncauj raw cov ntaub ntawv yog engineered rauruaj khov kev ua tau zoo, ua rau lawv haum rau ob leegphau ntawv txhaj tshuaj thiab automated grouting khoom. Cov neeg cog lus tau txais txiaj ntsig los ntawmLub sij hawm tsim kho luv luv, tus nqi zog qis dua, thiab zoo ib yam ntawm - kev ua haujlwm ntawm qhov chaw.
Cov ntaub ntawv no yog siv dav hauv:
Qhob slab lifting thiab leveling
Void sau nyob rau hauv txoj kev loj thiab kev hauv nroog
Tiv thaiv kev txij nkawm ntawm kev laus pavements
Nrog kev lag luam thoob ntiaj teb hloov mus rautxhim kho txoj kev zoo, polyurethane rigid ua npuas ncauj raw cov ntaub ntawv tau dhau los ua ib qho kev xaiv zoo rau cov neeg cog lus thiab cov khoom xa khoom.
