DDPU-301 polyurethane grouting mea no ka hoʻopakele a me ka hoʻomaha
DDPU-301 polyurethane grouting mea no ka hoʻopakele a me ka hoʻomaha
OLELO HOOLAHA
ʻO DDPU - 301 kahi mea ʻelua hydrophobic polyurethane grouting material, i hoʻolālā ʻia no ka hoʻopakele a me ke kōkua.He pōkole loa ka manawa pane a hoʻololi koke ʻia mai kahi wai a hiki i ko lākou ʻano hupa hope loa.ʻAʻole hiki i kēia mea ke hoʻopili wale i ka wai, akā loaʻa pū kekahi i ka hopena hoʻoikaika a me ka stabilization.Ua hoʻohana nui ʻia i loko o nā kaila subway, conservancy wai a me ka hydropower, ka hale kaʻa ma lalo o ka honua, ka ʻōpala a me nā māla ʻē aʻe o ka wai leakage-plugging.
HI'O
A. Hoʻopili wikiwiki me ka wai, hoʻonui a hoʻōla i ka huʻa.Hiki ke hoʻoponopono ʻia ka manawa pane e like me ka nui o ka mea A, maʻamau hiki ke hoʻomalu ʻia e hoʻōla i nā ʻumi kekona a i mau minuke.
B. He maikaʻi ke kūpaʻa kemika.
C. Ka ikaika kiʻekiʻe.Hiki i ka ikaika compressive ke hele ma luna o 20MPa i loko o kekahi mau hola ke hoʻoheheʻe ʻia ma lalo o nā kūlana airtight;
D. Me ka nui infiltration radius a me ka solidification leo lākiō, wikiwiki kemika hopena.Ke hui ka mea i ka wai, e hana ʻia ke kaomi hoʻonui nui e pana i ka slurry i loko o ka māwae e hana i kahi hoʻohui paʻakikī.

HOOLAHA
A. Seam sealing a me ka uhi ʻana i ka wai anticorrosive o ka loko wai, hale kiaʻi wai, ka hale haʻahaʻa, ka hale hoʻoneʻe ea a me nā hale ʻē aʻe;
B. Anticorrosion o nā pipeline metala a me nā mea hana kila;
C. ʻO ka hoʻomaʻamaʻa lepo ， kaila ma lalo o ka honua a i ʻole ka hoʻoikaika ʻana i ke kahua kūkulu;
D. ʻO ka hoʻopaʻa ʻana a me ka hoʻoikaika ʻana i nā seams deformation, nā hui kūkulu a me nā māwae kūkulu i nā papahana kūkulu;
E. Ka hoʻopaʻa ʻana i ka leaka a me ka hoʻoikaika ʻana i nā awa, nā uwapo, nā uwapo, nā pā a me nā kikowaena wai;
F. Pale pale a me ka leak plugging i ka geological drilling, koho wai plugging i ka aila hana, a me ka wai hooki-hushing i loko o ka mine, etc.
KA PIKI, HOOMAHA A ME KA HELE
A. E mālama ʻia ka huahana i loko o nā pahu hao maʻemaʻe, maloʻo a paʻa i ka ea me ka nui o 20kg / pahu a i ʻole 10kg / pahu;
B. Hōʻalo i ka ua, hoʻolaha, extrusion a me ka hui ʻana i ka wā o ka lawe ʻana e hōʻoia i ka maikaʻi o ka pūʻolo;
C. Pono e mālama ʻia ka huahana ma kahi ventilated, maloʻo a me ka ʻoluʻolu e pale aku i ka lā a me ka ua.
D. Ma lalo o nā kūlana mālama maʻamau, he 6 mahina ka manawa mālama
