I-DDPU-301 i-polyurethane grouting imathiriyeli yokuhlangula kunye nokukhululeka
INTSHAYELELO
I-DDPU - 301 zizinto ezimbini ze-hydrophobic polyurethane grouting, eyenzelwe ukuhlangula kunye nokukhululeka.Izinto eziphathekayo zinexesha elifutshane kakhulu lokuphendula kwaye ziguqule ngokukhawuleza ukusuka kulwelo ukuya kwifom yabo yokugqibela ye-foam.Esi sixhobo asikwazi nje ukuvala amanzi, kodwa sinokuqiniswa okuthile kunye nomphumela wokuzinzisa.Isetyenziswe ngokubanzi kwiitonela zendlela engaphantsi komhlaba, ukugcinwa kwamanzi kunye nombane wamanzi, igaraji engaphantsi komhlaba, umjelo ophantsi komhlaba ohambisa amanzi amdaka kunye nezinye iindawo zokuvala ukuvuza kwamanzi.
IIMBONAKALO
A. Ukusabela ngokukhawuleza ngamanzi, ugwebu olukhawulezayo lwandisa kwaye lunyange.Ixesha lokuphendula lingahlengahlengiswa ngokobungakanani becandelo A, ngokubanzi linokulawulwa ukunyanga kumashumi emizuzwana ukuya kwimizuzu.
B. Uzinzo lwekhemikhali lugqwesileyo.
C. Amandla aphezulu.Amandla oxinzelelo anokuhamba ngaphezulu kwe-20MPa kwiiyure ezimbalwa xa ubumba phantsi kweemeko zomoya;
D. Ngerediyasi enkulu yokungena kunye nomlinganiselo womthamo wokuqina, ukusabela kweekhemikhali ngokukhawuleza.Xa imathiriyeli idibana namanzi, uxinzelelo olukhulu luya kwenziwa ukutyhala i-slurry nzulu kwi-crack ukwenza udibaniso olunzima.

IXESHA LOKUPHENDULA
Ixesha lokuphendula lixhomekeke kuphela kwiqondo lokushisa lamatye, kodwa nakwiqondo lokushisa kwemveliso.Ixesha lokusabela phantsi kwedosi ye-catalyst eyahlukeneyo ilinganiswa phantsi kweemeko zebhubhoratri, kwaye kungcono ukuqhuba iimvavanyo zentsimi phambi kokugaya.

ISICELO
A. Ukutywinwa komthungo kunye nokwaleka kwamanzi okunqanda ukubola kwechibi, inqaba yamanzi, indawo engaphantsi komhlaba, indawo yokuhlala yohlaselo lomoya kunye nezinye izakhiwo;
B. I-Anticorrosion yeepayipi zetsimbi kunye nekhonkrithi kunye nezakhiwo zetsimbi;
C. Ukucocwa kothuli, itonela engaphantsi komhlaba okanye ukomelezwa kwesiseko;
D. Ukutywinwa kunye nokomelezwa kwee-deformation seams, ii-joints zokwakha kunye neentanda zezakhiwo kwiiprojekthi zokwakha;
E. Ukutywina ukuvuza kunye nokomeleza amazibuko, iindawo zokuloba, iipier, amadama kunye nezikhululo zombane;
F. Ukukhuselwa kweendonga kunye nokuvuza kweplagi kwi-geological drilling, ukufakwa kwamanzi okukhethiweyo ekusetyenzisweni kweoli, kunye nokuyeka ukukhupha amanzi emgodini, njl.
UKUPAKISHA, UKUGCINWA KUNYE NEZOTHUTHO
A. Imveliso iya kugcinwa kwimigqomo yentsimbi ecocekileyo, eyomileyo kwaye engenamoya enomthamo we-20kg/igubu okanye i-10kg/igubu;
B. Gwema imvula, i-exposure, extrusion kunye nokungqubana ngexesha lokuthutha ukuqinisekisa ukuba iphakheji ikwimeko efanelekileyo;
C. Imveliso kufuneka igcinwe kwindawo engena umoya, eyomileyo kwaye epholileyo ukunqanda ilanga elithe ngqo kunye nemvula. Ubushushu bokugcina kufuneka bungabi ngaphezulu kwama-40 ℃;
D. Ngaphantsi kweemeko eziqhelekileyo zokugcina, ixesha lokugcinwa ziinyanga ezi-6
