DDPU-301 polyurethane grouting zinthu zopulumutsa ndi mpumulo
MAU OYAMBA
DDPU - 301 ndi zigawo ziwiri za hydrophobic polyurethane grouting, zopangidwira kupulumutsa ndi mpumulo.Zinthuzo zimakhala ndi nthawi yaifupi kwambiri ndipo zimasintha mwachangu kuchoka pamadzi kupita ku mawonekedwe awo omaliza a thovu.Izi sizingangotseketsa madzi, komanso zimakhala ndi mphamvu zowonjezera komanso zokhazikika.Zakhala zikugwiritsidwa ntchito kwambiri munjira zapansi panthaka, posungira madzi ndi mphamvu ya hydropower, garaja yapansi panthaka, sewero ndi madera ena otsekera madzi osatulutsa madzi.
MAWONEKEDWE
A. Mofulumira kuchitapo kanthu ndi madzi, kutulutsa thovu mwachangu kumakulitsa ndikuchiritsa.Nthawi yochitira zitha kusinthidwa molingana ndi kuchuluka kwa gawo A, nthawi zambiri imatha kuwongoleredwa kuchiritsa mumasekondi makumi angapo mpaka mphindi.
B. Kukhazikika kwa Chemical ndikwabwino kwambiri.
C. Mphamvu zapamwamba.Mphamvu yopondereza imatha kupitilira 20MPa mkati mwa maola ochepa mukamawumba pansi pamikhalidwe yopanda mpweya;
D. Ndi lalikulu lolowera kulowererapo ndi solidification voliyumu chiŵerengero, mofulumira mankhwala anachita.Zinthu zikakumana ndi madzi, mphamvu yokulirapo imapangidwa kuti ikankhire slurry mozama mumng'aluyo kuti iphatikize mwamphamvu.

APPLICATION
A. Kusindikiza kwa msoko ndi zokutira zoletsa kuwononga madzi za dziwe, nsanja yamadzi, chipinda chapansi, pogona mpweya ndi nyumba zina;
B. Anticorrosion wa zitsulo ndi mapaipi konkire ndi nyumba zitsulo;
C. Kuchiza fumbi, ngalande yapansi panthaka kapena kulimbitsa maziko;
D. Kusindikiza ndi kulimbitsa mapindikidwe seams, zolumikizira zomangamanga ndi ming'alu ya zomangamanga muzomangamanga;
E. Kutsekereza kutayikira ndi kulimbitsa madoko, makopo, mabwalo, madamu ndi malo opangira magetsi;
F. Kuteteza khoma ndi kutsekera kobowola mu geological kubowola, kuyika madzi osankhidwa mukugwiritsa ntchito mafuta, ndi kuyimitsa madzi mumgodi, ndi zina zotero.
KUTENGA, KUSINTHA NDIPONSO NTENDO
A. Mankhwalawa azisungidwa mu ng'oma zachitsulo zaukhondo, zowuma komanso zopanda mpweya ndi voliyumu ya 20kg/ng'oma kapena 10kg/mgolo;
B. Pewani mvula, kuwonekera, kutuluka ndi kugundana panthawi yoyendetsa kuti muwonetsetse kuti phukusi liri bwino;
C. Zogulitsazo ziyenera kusungidwa pamalo opumira mpweya, owuma komanso ozizira kuti asatengere dzuwa ndi mvula. Kutentha kosungirako sikuyenera kupitirira 40 ℃;
D. Pansi posungira bwino, nthawi yosungira ndi miyezi isanu ndi umodzi
