In the production of acrobatic clown fiberglass sculpture, in addition to the importance of raw materials, fiberglass processing technology is also very meticulous and professional, every link to achieve excellence.
In order to remove grease scale and rust spots, mechanical processing and chemical treatment can also be carried out according to the requirements of use. The specific pretreatment contents are as follows:
(1) Degreasing treatment includes the physical-mechanical method (wiping method, combustion method, injection method) and physical-chemical method (solvent degreasing method, alkali degreasing method, emulsion degreasing method and electrolytic degreasing method).
(2) Rust removal treatment includes physical method (mechanical sandblasting, shot blasting, artificial, sand cloth rust removal, etc.) and chemical method (acid pickling, electrolytic acid pickling, alkali solution rust removal, etc.).
(3) Phosphating (oxidation) treatments mainly include non-ferrous metals, their alloys and iron, and steel. For non-ferrous metals and alloys, chemical oxidation, anodic oxidation (aluminum and aluminum alloy), phosphoric acid and chromic acid (zinc and its alloys) are mostly used; for iron and steel, phosphoric acid, chromic acid, and nitric acid are mostly used.
In a word, the surface pretreatment before the white embryo painting of acrobatic clown fiberglass statue sculpture is an extremely important process. Only by ensuring the quality of surface treatment, can the best fiberglass sculpture painting effect be obtained.
