1、 Inorganic impregnating agent
Infiltration agent, also known as impregnating agent, sealing agent and impregnating glue, is mainly used to seal the leakage micropores, sand holes or gaps in metal castings, so that these poor leakage products can be used again as qualified products; The impregnating agent can also be used for sealing holes, improving electroplating effect and machining of various P/M parts (metal sintered body). It is an indispensable processing technology in the field of material improvement. Inorganic impregnating agent Low cost, simple operation and high temperature resistance 。

three Advantages and disadvantages of inorganic infiltration and agricultural production system infiltration
Advantages: inorganic infiltration temperature resistance eight hundred The agricultural production system can only withstand 200 ℃
Disadvantages: 1. There are many residues on the surface of inorganic infiltration, affecting the appearance, and there is no residue in the agricultural production system
two Inorganic infiltration is brittle and easy to fall off after vibration. The agricultural production system infiltration is thermosetting plastic with good toughness
three The qualification rate of inorganic infiltration is low, the secondary infiltration can only be 80%, and the qualification rate of agricultural production system is 98%
four Inorganic infiltration is easy to seal screw holes, and through holes waste time. Infiltration in agricultural production system is not blocked
five Inorganic infiltration is characterized by high electricity cost for baking and curing (230 ℃), while the agricultural production system infiltration is characterized by low electricity cost for 90 ℃ hot water curing
six The cost of inorganic impregnating glue is low, and the cost of impregnating glue in agricultural production system is slightly high
Infiltrate the cost of inorganic infiltration and agricultural production system according to your requirements Cost comparison (calculated by one ton of product)
Glue cost: inorganic two hundred and fifty element Agricultural production system four hundred element
Cure electricity cost: inorganic one hundred and eighty element Agricultural production system thirty element
Other consumption costs are the same
The consumption cost of agricultural production system infiltration is basically the same as that of inorganic infiltration
Inorganic infiltration rework 20% cost two hundred element
As per one ton of qualified products : The cost of inorganic infiltration is higher than that of agricultural production system two hundred RMB (excluding the cost of your through-hole)
