Plastic dipping liquid can be divided into two categories, one is smooth dipping, and the other is hemp dipping. In these two categories, different soft hardness and different colors can be divided. According to different needs, different products such as anti-aging, acid and alkali resistance, and corrosion resistance can be formulated.
First pour the dipping solution into the dipping jar and let it stand for about 30 minutes.
The second step is to put the clean parts to be crisped on the shelf, and preheat it in an oven at 200 ° C to 280 ° C for about 5 to 10 minutes.
The third step is after removing the parts shelf from the oven. Immediately start dipping, dipping at a speed of about 10 mm / s (must be uniform), stay for about 2 to 3 seconds, and then leave the dipping solution at a uniform speed, leaving about 2 mm / s (must be slow and uniform). pause.
The fourth step is to put the dipped parts together with the shelf in an oven at 200 ° C to 280 ° C for 3 minutes.
Finally, after removing the component rack from the oven, it can be sufficiently cooled with water or air (about 3 minutes). After the surface is hardened and will not be pinched, remove the tip of the nose to complete the dipping.
