聚氨酯灌漿材料（OPU) Polyurethane Grouting Material (OPU)
單組份OPU發泡堵水液（疏水性）
|
聚氨酯灌漿材料（油溶性）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。油溶性聚氨酯灌漿材料形成的固結體強度大、抗滲好，適用于加固地表和防水兼備的工程。
一、該產品具有以下特點：
1.膨脹率大，不收縮、抗滲性強。
2.強度高，干裂縫和濕裂縫均可施工，與水反應生成的固結體把水擠出來，達到防水補強加固作用。
3.注漿設備與工藝簡單，投資費用少。 |
Polyurethane Grouting Material (oil-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.The solid formed by the new grouting material is high-strength and waterproof, thus conveniently used for projects which demand both surface reinforcement and waterproof functions.
Ⅰ. Product Characteristics
1. High expansion, no contraction and excellent waterproof features.
2. High strength, used for both dry cracks and wet cracks. The solid generated by reaction with water can squeeze the water out to realize the waterproof, reinforcement and strengthening functions.
3. 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.
3. No crash, direct sunshine, exposure to rain or smoke during transportation.
