Clump weight can also improve its balance using other shapes, and operating platform and mounting platform upper surface maintain an equal level,
Mounting platform lower end is sagging, and lower end surface is lower than the lower end surface of operating platform, and entire clump weight is made to form a balanced lever.
The spraying method of above-mentioned clump weight, including following treatment process:
A) soil is mended in polishing, is checked the flatness of workpiece surface, is polished；It is filled up at recess and gap using dirt,
It is polished again after filling up using the sand paper of 800# or 1000#, keeps workpiece surface smooth, adhered to convenient for paint and workpiece；
B) grease removal dedusting is first sprayed or is embathed to the workpiece after dedusting using 5-10% non-phosphor degreaser solution, and surface oil is removed
Rouge is reduced influence of the grease to paint and workpiece adhesive force, is then cleaned using tap water to workpiece surface, used again after cleaning
First time pure water is cleaned, and workpiece surface grease and non-phosphor degreaser Liquid Residue are removed, and then uses organosilan dilution again
The rust powder of workpiece surface is handled, is sprayed convenient for the paint of subsequent workpiece, is heaved after being beneficial to prevent paint drying
Or situations such as splitting；
C) cleaning destatics, and by the clump weight after organosilan cleaning in step B), removes counterweight using second of pure water cleaning
The rust powder and silane Liquid Residue on block surface, then third time pure water cleans the electrostatic removed in counterweight, thoroughly removes remaining rust
Powder and silane Liquid Residue are removed workpiece electrostatic by the modes such as spraying or embathing, can first to workpiece using pure water into
Row soaking and washing 3-5 minutes, spray then is carried out 2-4 minutes to workpiece again, cleaning situation is checked, people can be passed through again as needed
Rust powder or silane Liquid Residue in work spray removal workpiece gap, are carrying out draining for workpiece, remove most of ponding on workpiece,
Most of ponding is drained, convenient for improving the subsequent drying efficiency to workpiece, while using repeatedly destaticing, convenient for improving workpiece
The effect of upper electrostatic removal, influence when reducing to spraying, convenient for improving the adhesive force between paint and workpiece；
D) dry heat, the workpiece after destaticing to cleaning is air-dried using 100-300 DEG C of hot wind, especially at connection gap
It is dry, it is adjustable as needed to air-dry temperature because the thickness of the material of workpiece is different, while being conducive to the pre- thermal effect to workpiece
Fruit is heated evenly convenient for workpiece, and the workpiece after drying carries out pressure cooling using strong fan, and temperature is reduced to 45-50 DEG C
Room temperature, while reducing and expanding with heat and contract with cold spraying is impacted, prevent crack or raised points occur after paint is dry；
