Embodiment 1
[0041] The application discloses a check valve casting and its processing technology. The surface of the check valve casting is treated with a surface treatment agent. The surface treatment agent includes the following raw materials: styrene-maleic anhydride copolymer, Cr 3 Si, 1,6-hexanediol diacrylate, 4-(benzylthiol)phenol, catalyst tetraethoxytitanium and isooctyl polyoxyether ester; the processing technique includes the following steps:
[0042] S1. surface treatment agent preparation; first styrene-maleic anhydride copolymer, isooctyl alcohol polyoxyether ester and Cr 3 Si was stirred and mixed for 5 minutes at a speed of 120r / min, and then 1,6-hexanediol diacrylate and catalyst tetraethoxytitanium were added, stirred and mixed, and the temperature was raised to 50°C, and 4-(benzylthio Alcohol) phenol stirs the product that obtains for 30min, finally stirs 1h, makes surface treatment agent, and insulation is stand-by;
[0043] S2. Thermal spraying; keep the check valve ...
