4, 2～4%CrO
3, 82～88% distilled water; Pnenolic aldehyde bakelite holder is put into 75～85 ℃ mixed acid solution and was soaked 1～5 minute, takes out retainer and puts into clear water and soaked 30～50 seconds; 5% sodium carbonate liquor that pnenolic aldehyde bakelite holder after handling is put into 55 ℃～65 ℃ soaked 1～3 minute; With in the alkali and after pnenolic aldehyde bakelite holder put into mobile clear water and washed 4～8 minutes; Pnenolic aldehyde bakelite holder was put into the supersonic wave cleaning machine ultrasonic cleaning 5～10 minutes; Pnenolic aldehyde bakelite holder after the ultrasonic cleaning put into 110 ℃～120 ℃ dry 3～5 hours of thermostatic drying chamber.Solve pnenolic aldehyde bakelite holder and can only adopt artificial removal's Burr Problem, had good practical function.
Description
Technical field
The invention belongs to the engineering plastic surface processing technology field, specially refer to a kind of pnenolic aldehyde bakelite holder acid washing burr removal technology.
Background technology
Pnenolic aldehyde bakelite holder is usually used on high speed, the precision bearing, the removal of the burr that in the mechanical processing process of pnenolic aldehyde bakelite holder, produces at present, big and retainer product wall thickness mainly adopts is the method for vibration finishing for size, promptly use abrasive material, abrasive particle to remove the burr of retainer.For thin-walled, miniature or retainer product that structural shape is special,, can only adopt manually method to remove the burr of retainer at present because its mechanical strength is lower.
Summary of the invention
At above-mentioned existing problems, the present invention proposes a kind of pnenolic aldehyde bakelite holder acid washing burr removal technology, this technology is not only simple and efficient but also can guarantee product quality.
For achieving the above object, the present invention has adopted following technical scheme:
Described pnenolic aldehyde bakelite holder acid washing burr removal technology is by preparing a kind of mixed acid solution, pnenolic aldehyde bakelite holder is soaked in mixed acid solution, and pass through alkali neutralization, water flushing, ultrasonic cleaning, dehydration with the removal of retainer burr, its technical process is as follows:
I, mixed acid solution
Mixed acid solution constitutes by weight percentage: 2～4%HNO
3, 4～5%H
2SO
4, 4～5%H
3PO
4, 2～4%CrO
3, 82～88% distilled water;
II, acid treatment
The mixed acid solution that pnenolic aldehyde bakelite holder is put into 75 ℃～85 ℃ soaked 1～5 minute, and the taking-up retainer is put into clear water and soaked 30～50 seconds;
III, alkali neutralization
5% sodium carbonate liquor that pnenolic aldehyde bakelite holder after handling is put into 55 ℃～65 ℃ soaked 1～3 minute;
IV, water flushing
With in the alkali and after pnenolic aldehyde bakelite holder put into mobile clear water and washed 4～8 minutes;
V, ultrasonic cleaning
Pnenolic aldehyde bakelite holder was put into the supersonic wave cleaning machine ultrasonic cleaning 5～10 minutes;
VI, dehydration
Pnenolic aldehyde bakelite holder after the ultrasonic cleaning put into 110 ℃～120 ℃ dry 3～5 hours of thermostatic drying chamber.
Because adopt aforesaid technical scheme, the present invention has following superiority:
The invention solves thin-walled, pnenolic aldehyde bakelite holder product miniature or that structural shape is special can only adopt manually method to remove the problem of the burr of retainer at present, not only guarantee product quality but also improved operating efficiency greatly, had good practical function.The present invention also can be used for the pnenolic aldehyde bakelite holder product of size than big and wall thickness.
