When using silica gel should pay attention to what matters:
A tool dedicated:
Tank sealant mixture and stirred containers need special equipment, other materials can not be stirred before use. Alternatively container materials are PP, PE plastic barrels, ceramic, stainless steel, etc; stirring devices to choose from, stainless steel, rigid plastic rods, bamboo, sticks can be.
Second, the need to solidify the anti-interference:
Certain materials, chemicals, curing agents and plasticizers can inhibit the cure gel, these substances should be aware of:
1, the organic tin and tin-containing silicone rubber;
2, sulfur, polysulfide or sulfur-containing compounds article;
3, amines, ammonia or urethane rubber articles;
4, phosphorous or phosphorous-containing materials; acidic materials (acids);
5, flux residues; if used in high efficiency air filters aluminum tank seal, basically there will be no more than a few aspects of the problem;
Third, the indicator:
No blue pigment in the special function of gum, may have been added; however, the actual mixing glue, prolonged mechanical repetition of doing the same error occurs, so component inside which add a blue pigment as indicator . Use it to distinguish between A, B component, to remind users to avoid making mistakes, and easy to observe whether a place has Glue (because silica is colorless and transparent). Place a long time, B component will be a small amount of blue pigments sink to the bottom, it will not affect the curing and sealing effect of colloids, continue to use the eggs.
