2) table is adjusted: joined in table tune liquid by the skeleton after once washing in step 1, stir 10-20 minute;
3) degreasing: the skeleton after first being adjusted by table in step 2 adds the acid solution adding inhibiter to and carries out pickling, and the time is 50-55 minute, and temperature is 40-45 DEG C;
4) secondary washing: the skeleton after pickling in step 3 is washed, add the acid of trace in water lotion, keep 6.5 < PH < 7 of water lotion, and stir during washing, the temperature of washing is 30-35 DEG C, and the time is 60-70 minute;
5) three washings: again washed by the skeleton after washing in step 4, the temperature of washing is 40-45 DEG C, and the time of washing is 60-65 minute;
6) hot water wash: the skeleton after three washings in step 5 is carried out hot water wash, and the temperature of washing is 70-89 DEG C, the time 50-60 minute of washing;
7) dry: the skeleton after hot water wash in step 6 is carried out room temperature and leaves standstill, time of repose is 30-35 minute, then toasted by the skeleton after leaving standstill, during baking, temperature is 50-60 DEG C.
Further, its step is as follows:
1) once wash: first polished by skeleton, the time is 8 minutes, then is washed by skeleton, and the temperature of washing is 28 DEG C, the time is 32 minutes;
2) table is adjusted: joined in table tune liquid by the skeleton after once washing in step 1, stir 15 minutes;
3) degreasing: the skeleton after first being adjusted by table in step 2 adds the acid solution adding inhibiter to and carries out pickling, and the time is 55 minutes, and temperature is 42 DEG C;
4) secondary washing: the skeleton after pickling in step 3 is washed, add the acid of trace in water lotion, keep 6.5 < PH < 7 of water lotion, and stir during washing, the temperature of washing is 33 DEG C, and the time is 65 minutes;
5) three washings: again washed by the skeleton after washing in step 4, the temperature of washing is 41 DEG C, and the time of washing is 60-65 minute;
6) hot water wash: the skeleton after three washings in step 5 is carried out hot water wash, and the temperature of washing is 78 DEG C, the 58 minutes time of washing;
7) dry: the skeleton after hot water wash in step 6 is carried out room temperature and leaves standstill, time of repose is 34 minutes, then toasted by the skeleton after leaving standstill, during baking, temperature is 60 DEG C.
Beneficial effect of the present invention is: the automobile shock shock-absorbing part that the present invention adopts above-mentioned independent phosphating process to manufacture, the phosphatize phosphate coat uniform and delicate more on the skeleton surface of process, and save the time, improve efficiency, washing is more abundant, makes the phosphatization better effects if of automobile shock shock-absorbing part, good physical properties simultaneously, make the traveling of automobile more steady, safety and weather resistance better, are 1.5 times of the life-span of orthodox car vibration damper part.
