The epoxy resin skimmer can be eliminated rapidly when weighting agent stirs and produce bubble, helps reducing the weighting agent surface tension, the resistance when reducing weighting agent perfusion pipeline effectively.Simultaneously weighting agent there is wetting action, is difficult for producing " flake " or " cavity ".
Special construction in the ZY-1618 solidifying agent molecule can be under normal temperature or coldcondition plays crosslinking reaction with epoxy resin fully, and does not produce by product, and is nontoxic, cohesiveness, snappiness, the insulativity of excellence arranged, water-fast, resistance to chemical attack.
The present invention has following advantage:
1. preparation is easy, instant joining, easy and simple to handle.Once perfusion can be accomplished, and does not need after-teeming, pours into and can prepare (preparing in the 5min) immediately when not enough.
2. RF-400 both can increase CYD-128 epoxy resin snappiness efficiently, also can dilute epoxy resin, reduced the viscosity of CYD-128 epoxy resin, increased the flowability of weighting agent of the present invention, was convenient to perfusion.
3. when the weighting agent mixed solution stirs, add skimmer, can eliminate producing bubble when stirring rapidly, help reducing the weighting agent surface tension, the resistance when reducing weighting agent perfusion pipeline effectively.Simultaneously weighting agent there is wetting action, is difficult for producing " flake " or " cavity ".
4. DMP-30 can reduce weighting agent solidification value of the present invention effectively, shorten set time (solidifying fully behind the 2h), helps keeping the pipeline original appearance, is difficult for making casting mold to produce distortion.
