I-DDPU-301 polyurethane grouting impahla yokuhlenga nokukhululeka
ISINGENISO
I-DDPU - 301 iyizingxenye ezimbili ze-hydrophobic polyurethane grouting material, eklanyelwe ukuhlenga nokukhulula.Izinto ezisetshenziswayo zinesikhathi esifushane kakhulu sokuphendula futhi zishintsha ngokushesha zisuka oketshezini ziye efomini yazo yokugcina yegwebu.Lokhu okuqukethwe akukwazi nje ukuxhuma amanzi, kodwa futhi kunomphumela othile wokuqinisa nokuqiniswa.Isetshenziswe kabanzi emihubheni yesitimela esihamba ngaphansi komhlaba, ukongiwa kwamanzi kanye namandla kagesi, igaraji elingaphansi komhlaba, indle kanye nezinye izinkambu zokuxhuma ukuvuza okungangeni manzi.
IZICI
A. Ukusabela ngokushesha ngamanzi, ukukhihliza amagwebu ngokushesha kunwebeka futhi kwelaphe.Isikhathi sokuphendula singashintshwa ngokuya ngenani lengxenye A, ngokuvamile singalawulwa ukuze zelaphe emashumini amasekhondi kuya kumaminithi.
B. Ukuzinza kwamakhemikhali kuhle kakhulu.
C. Amandla aphezulu.Amandla acindezelayo angadlula ku-20MPa emahoreni ambalwa lapho ebumba ngaphansi kwezimo zomoya;
D. Ngerediyasi enkulu yokungena kanye nesilinganiso sevolumu yokuqina, ukusabela kwamakhemikhali okusheshayo.Lapho impahla ihlangana namanzi, kuzokwenziwa ingcindezi enkulu yokunweba ukuze kuphushwe udaka kujule emfantwini ukuze kwakheke ukuhlanganisa okunzima.

ISIKHATHI SOKUSENZA
Isikhathi sokuphendula asixhomekile kuphela ekushiseni kwedwala, kodwa futhi ekushiseni komkhiqizo.Isikhathi sokuphendula ngaphansi komthamo ohlukile we-catalyst silinganiswa ngaphansi kwezimo zaselabhorethri, futhi kungcono ukuqhuba izivivinyo zensimu ngaphambi kokukhipha i-grouting.

ISICELO
A. Ukuvalwa kwe-Seam kanye ne-anticorrosive anticorrosive coating ye-pool, umbhoshongo wamanzi, indawo engaphansi, indawo yokukhosela yokuhlasela emoyeni nezinye izakhiwo;
B. I-Anticorrosion yamapayipi ensimbi nawokhonkolo kanye nezakhiwo zensimbi;
C. Ukwelashwa ngothuli, umhubhe ongaphansi noma ukuqinisa isisekelo sesakhiwo;
D. Ukuvalwa nokuqiniswa kwama-deformation seams, amajoyinti okwakha kanye nokuqhekeka kwesakhiwo kumaphrojekthi wokwakha;
E. Ukuvala ukuvuza nokuqinisa amachweba, izikebhe, izinsika, amadamu neziteshi zokuphehla ugesi ngamanzi;
F. Ukuvikela udonga kanye nokuxhunywa kokuvuza kokumba i-geological drilling, ukuxhunywa kwamanzi okukhethayo ekuxhashazweni kukawoyela, kanye nokuyeka ukugeleza kwamanzi emayini, njll.
UKUPAKA, UKUGCINWA KANYE NEZOKUTHUTHA
A. Umkhiqizo kufanele ugcinwe emigqomeni yensimbi ehlanzekile, eyomile futhi engangeni moya enomthamo ongu-20kg/isigubhu noma u-10kg/isigubhu;
B. Gwema imvula, ukuchayeka, i-extrusion kanye nokushayisana ngesikhathi sokuthutha ukuze uqinisekise ukuthi iphakheji isesimweni esihle;
C. Umkhiqizo kufanele ugcinwe endaweni engenawo umoya, eyomile futhi epholile ukuze kugwenywe ukukhanya kwelanga nemvula. Izinga lokushisa lokugcina akufanele libe ngaphezu kuka-40 ℃;
D. Ngaphansi kwezimo zokulondoloza ezivamile, isikhathi sokulondoloza yizinyanga eziyisi-6
