聚氨酯灌浆材料(OPU) Polyurethane Grouting Material (OPU)
单组份OPU发泡堵水液(疏水性)
  聚氨酯灌浆材料(油溶性)是应用于水池、大坝基础、隧道、矿井等土木工程、水利水电、交通、地下工程混凝土裂缝修补、灌浆堵漏、帷幕防渗、加固补强等工程的新型灌浆材料。油溶性聚氨酯灌浆材料形成的固结体强度大、抗渗好,适用于加固地表和防水兼备的工程。

一、该产品具有以下特点:
  1.膨胀率大,不收缩、抗渗性强。
  2.强度高,干裂缝和湿裂缝均可施工,与水反应生成的固结体把水挤出来,达到防水补强加固作用。
  3.注浆设备与工艺简单,投资费用少。
  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、施工工艺
  1.仔细检查漏水部位,清理裂缝附近污物,以备灌浆。
  2.布孔:在裂缝处打灌注孔,对深层裂缝可以钻斜孔穿过缝面,一般孔距0.2-0.5米,深度为混凝土厚度1/2左右。
  3.埋嘴封缝:埋入灌浆嘴,用快干水泥埋嘴封缝。
  4.灌浆:根据缝的具体情况确定灌浆压力,灌浆量,当邻孔出现浆液时,移至邻孔,在规定压力下并浆,直至达到灌浆结束标准。
  5.浆液固化后去除灌浆管,用快干水泥封闭。
  6.结束后用丙酮清洗注浆机及其他工具。

四、注意事项
  1.必须在专业人员指导下施工,并配带必要的防护工具。
  2.请使用专业注浆机,推荐使用LB-518型高压注浆机。
  3.避免液料喷入眼内,万一喷到,请立即用清水冲洗。
  4.施工场所必须侧通风,禁止烟火并注意用电安全。

五、包装及储运
  1.10kg/桶,20kg/桶。
  2.本品贮存在干燥、通风、阴凉处,保质期自生产之日起未启封6个月。

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.
