The essential difference between organic infiltration agent and inorganic infiltration agent

In general, the type of infiltrant is inorganic infiltrant and organic infiltrant. In general use, the cost of organic infiltrant will be higher, but the effect is much better than inorganic infiltrant. Therefore, more and more companies now choose to use organic impregnation machines. So, what is the difference between organic infiltrants and inorganic infiltrants? Let me give you a specific introduction:

 1. The inorganic infiltrant is composed of several inorganic substances, such as sodium silicate. Impregnant Sealant is a liquid substance prepared from dozens of organic substances.

Second, the performance and requirements of the infiltration agent (impregnation liquid):

 1. Basic performance requirements of infiltration agent:

It has good permeability to casting defects, and the infiltrant should also have non-toxic, non-polluting, non-flammable and good stability properties. When the infiltrant is cured, it should form a solid whole with the casting. The infiltrant cured product has good heat resistance, acid and alkali corrosion resistance, solvent resistance, irreversibility (will not change the infiltrant liquid or paste) and Mechanical properties closer to the substrate.

 2. New performance requirements for infiltration agents:

In addition to the above basic requirements, since infiltration has become a key production process for many factories, it is necessary to have good performance in terms of impregnation efficiency, energy saving and consumption reduction. Specifically,

New requirements 1. Easy to clean: Residual infiltrant is removed within 3 minutes, including residues in the screw holes.

New requirements 2, short curing time: 10 minutes to complete the curing.

New requirements 3, less consumption of infiltration agent: less residual infiltration agent on the workpiece.

 Third, the latest generation of organic infiltration agent (3 generations):

In order to meet the above three new requirements, the third generation of organic infiltration agent was developed in Japan in 1992. It is the latest and best, and there are few manufacturers. Many well-known large enterprises are using it, which fully meets the above three new requirements. .

 Comparison of four or three generations of organic infiltrant and inorganic infiltrant:

Taking the third-generation organic infiltration agent IMPRETECH YJ-85C as an example, the YJ-85C was successfully developed and put into commercial use during its work in Japan in 1992. In summary, although the inorganic infiltrant is 10 times cheaper than organic, the overall cost of inorganic infiltration is large, but the heat-resistant parts with a working temperature of 250 ° C to 300 ° C for a long time can only be infiltrated with inorganic infiltration. . In other cases, especially in mass production, organic infiltration should be used.
