DOPU-201 Eco-friendly Hydrophobic Polyurethane Grouting Mea
DOPU-201 Eco-friendly Hydrophobic Polyurethane Grouting Mea
FOLASAGA
DOPU-201 o se mea e fa'alelei-faauo tasi vaega hydrophobic polyurethane grouting mea.O lenei mea kemikolo grouting e gaosia e ala i le fa'afefiloi o polyols ma le isocyanate, ma fa'ai'u-upuni e isocyanate.O mea e mafai ona vave tali atu i le vai, o lona voluma e faʻalauteleina, e fausia ai se faʻafefe o le vai.O lenei mea e le gata e mafai ona faʻapipiʻiina e le susu, ae o loʻo i ai foi se faʻamalosia ma le faʻamautuina o aʻafiaga.Ua fa'aaogaina lautele i alavai alavai, conservancy vai ma hydropower, faletaavale i lalo o le eleele, sewer ma isi fanua o le leakage-plugging le susu.
FAAMATALAGA
A. hydrophobicity lelei ma mautu vailaau.
B. Fa'atasi ai ma le tele o le fa'asao, fua fa'atatau o le voluma ma le maualuga o le tali atu i le vai. O le tali atu i le vai e mafai ona fa'asa'olotoina le tele o le fa'alauteleina o le mamafa lea e tuleia ai le slurry e fa'asalalau i le loloto o le ta'eta'e e fausia ai se fa'atumauina fa'amalosi.
C. Lelei faʻamaʻi faʻamaʻi faʻamaʻi faʻasaga i vailaʻau, alkali ma soʻomea faʻalaʻau.
D. O le faʻapipiʻi e lamolemole, faʻafefeteina ma leai se faʻafefe.
U. Fa'apipi'i lelei ma fa'avae sima ma isi mea faufale.
F. O le viscosity ma le seti taimi e mafai ona fetuunai e tusa ai ma manaoga inisinia.

FAATONUGA
A. Fa'atumu fa'amaufa'ailoga su'isu'i ma fa'apipi'i fa'afefete le vai o tane Vai, olo vai, fogafale i lalo, malutaga ma isi fale;
B. Puipuiga o le u'amea o u'amea ma paipa sima ma fausaga u'amea;
C. Fa'avae fa'amalosia o alavai i lalo o le 'ele'ele ma fale ma le fa'amamaina o le palapala;
D. Le faʻamaufaʻailogaina ma le faʻamalosia o suʻega faʻaleagaina, faʻapipiʻi fau ma taʻetaʻe faʻavae i galuega faufale;
E. Fa'amauina le tafega ma le fa'amalosia o uafu, uafu, uafu, vai ma nofoaga eletise, ma isi;
F. Puipuiga o le puipui ma le leak plugging i le viliina eleele, filifili vai plugging i le faaaogaina o le suauu, ma le vai taofi-puna i totonu o le maina, ma isi.
