DDPU-301 polyurethane grouting abu don ceto da kuma taimako
GABATARWA
DDPU - 301 ne biyu-bangaren hydrophobic polyurethane grouting abu, tsara don ceto da kuma taimako. A kayan da sosai short dauki lokaci da sauri canza daga wani ruwa zuwa karshe kumfa form. Wannan abu zai iya ba kawai mai hana ruwa plugging, amma kuma yana da wani ƙarfafa kuma karfafawa sakamako. An yi amfani da ko'ina a cikin jirgin karkashin kasa tunnels, ruwa conservancy da kuma samar da wutar lantarki, a karkashin kasa gareji, lambatu da kuma sauran fannoni na hana ruwa yayyo-plugging.
FEATURES
A. Rapid amsa tare da ruwa, da sauri foaming fadada da kuma magani. A dauki lokaci za a iya gyara bisa ga adadin bangaren A, kullum za a iya sarrafawa don warkar da a dubun seconds zuwa minti.
B. Chemical kwanciyar hankali ne m.
C. High ƙarfi. A compressive ƙarfi iya tafi a kan 20MPa a cikin 'yan sa'o'i a lokacin gyare-gyaren karkashin airtight yanayi;
D. Da manyan infiltration radius da solidification girma rabo, m sunadarai dauki. Lokacin da kayan gamuwa ruwa, babban fadada matsa lamba za a generated wajen tura slurry zurfi a cikin crack samar da wata m (Abubakar).
