Method for sealing hole of injection-molding stainless steel product in silanization way and water solution formula and application of silane coupling agent

The invention discloses a method for sealing a hole of an injection-molding stainless steel product in a silanization way and a water solution formula and application of a silane coupling agent. The method for sealing the hole of the injection-molding stainless steel product in the silanization way and the water solution formula of the silane coupling agent can be widely applied to hole sealing treatment of all kinds of stainless steel powder forming pieces. By forming a silane film on the surface of the injection-molding stainless steel product, communicating holes of a steam treatment layer of the injection-molding stainless steel product can be effectively blocked, so that a corrosive medium is prevented from permeating a basal body through the communicating holes, and the corrosion resistance of the injection-molding stainless steel product is increased. A main substance used in the method is the silane coupling agent, the variety of silane coupling agents is rich, and the cost is cheap; the method for sealing the hole of the injection-molding stainless steel product in the silanization treatment way is simple in technology and easy to implement, confining liquid can be continuously used through component regulation after being used for a certain time, the cost is cheap, the environment is protected, and no pollution is generated.
