聚氨酯灌漿材料（WPU) Polyurethane Grouting Material (WPU)
單組份WPU發泡堵水液（親水性）
|
聚氨酯灌漿材料（水溶性）是應用于水池、大壩基礎、隧道、礦井等土木工程、水利水電、交通、地下工程混凝土裂縫修補、灌漿堵漏、帷幕防滲、加固補強等工程的新型灌漿材料。它遇水后立即反應，體積迅速膨脹，生成一種不溶于水，有較高強度和彈性的膠體，水溶性聚氨酯灌漿材料包水量大、滲透半徑大。
一、該產品具有以下特點：
1.漿液與水反應，形成不透水的固結體，可用于封堵強烈的涌水和阻止地基中的流水。
2.漿液生成固體物質的同時釋放氣體，漿液借助氣體的壓力可進一步壓進疏松的空隙中，使多孔性結構或地層裂縫能完全被漿液充填密實。
3.聚脂氨酯與土粒粘合力大，形成高強度彈性固結體，防止地基變形、龜裂、崩壞，從而使地基得到補強。
4.漿液的粘度、固化速度可以調節。注漿設備與工藝簡單，投資費用少。 |
Polyurethane Grouting Material (soluble) is a new type of grouting material used for concrete crack patching, grouting and blocking of water leakage, curtain anti-seepage, reinforcement and strengthening in civil engineering projects, hydraulic and hydroelectricity projects, transportation projects, underground projects including water pools, dam bases, tunnels, mines etc. It reacts with water immediately, expands quickly and generates a kind of colloid which is insoluble, high-strength and high resilient. So the material performs well with a big water content and infiltration radius.
Ⅰ. Product Characteristics
1. The slurry reacts with water and generates a insoluble solid which can be used to block strong gushing water or stop the running water in the foundation.
2. Air is released when the solid is generated. The air can further press the slurry into loose clearance, which can completely fill the porous structure or fracture formations with the slurry.
3. polyurethane produces strong adhesive force with soil and forms high-strength and resilient solid which can prevent soil deformation, cracks and collapse, thus reinforce the foundation.
4. The viscosity and curing rate can be adjusted. Investment is limited due to simple grouting equipment and techniques. |

三、施工工藝
1.仔細檢查漏水部位，清理裂縫附近污物，以備灌漿。
2.布孔：在裂縫處打灌注孔，對深層裂縫可以鉆斜孔穿過縫面，一般孔距0.2-0.5米，深度為混凝土厚度1/2左右。
3.埋嘴封縫：埋入灌漿嘴，用快干水泥埋嘴封縫。
4.灌漿：根據縫的具體情況確定灌漿壓力，灌漿量，當鄰孔出現漿液時，移至鄰孔，在規定壓力下并漿，直至達到灌漿結束標準。
5.漿液固化后去除灌漿管，用快干水泥封閉。
6.結束后用丙酮清洗注漿機及其他工具。
四、注意事項
1.必須在專業人員指導下施工，并配帶必要的防護工具。
2.請使用專業注漿機，推薦使用LB-518型高壓注漿機。
3.避免液料噴入眼內，萬一噴到，請立即用清水沖洗。
4.施工場所必須側通風，禁止煙火并注意用電安全。
五、包裝及儲運
1.10kg/桶，20kg/桶。
2.本品貯存在干燥、通風、陰涼處，保質期自生產之日起未啟封6個月。
3.運輸中不得碰撞、直曬、雨淋、防止煙火。

Ⅲ. Construction Technology
1. Check carefully the leakage parts clear the dirt around the cracks for grouting.
2. Hole Arrangement: cut grouting holes at cracks, cut slant holes for deep cracks to cross the quilt top. Commonly 0.2-0.5 meter space between each hole and one half of the concrete thickness as the depth of the holes.
3. Crack Sealing: put in grouting nozzle and seal the cracks with jet cement.
4. Grouting: set the grouting pressure and amount according to the specific crack conditions. When slurry can be seen in the neighboring hole, move to it, grout at the named pressure till the finishing grouting standards.
5. Remove the grouting nozzle when slurry is solidified and seal the crack with jet cement.
6. Clean the grouting machine and other tools with acetone after completing all the work.
Ⅳ. Note
1. The construction work shall be carried out under the instruction of professionals and necessary protection tools shall be applied.
2. Professional grouting machines shall be used, preferably type LB-518 grouting machine.
3. The slurry shall be avoided to get in eyes. In case it happens, clean with water immediately.
4. The construction site shall be ventilated, smoke or fire-prohibited; Power safety shall be noticed.
Ⅴ. Package, storage and Transportation
1. 10 or 20 kg per bucket.
2. Stored at dry, cool and ventilated places. Storage life one year unopened from the date of production.
