Dispatch of Chinese paint net / the coating surface exterior after classics is dry presents a lot of semicircle state protuberant, resemble the ripple like orange skin, this kind of phenomenon calls orange skin. As a result of,the phenomenon of skin of coating generation orange is more of coating shed smooth sex to differ place to cause. Shed the difference that make the same score a gender to have coating itself and construction undeserved wait for a variety of elements to cause. To prevent the generation of orange skin, should notice in construction:
(Processing of 1) ground floor is close friends, with close Qi Feng shuts white base to will conduce to stream smooth. Additional tegument besmears the surface wants sufficient burnish level, it is certain to be achieved spend glossily, so that assure the consistency with wet coating,reach coating spread smooth effect.
(The viscosity when 2) assures spray cannot too big.
(The watch after 3) assures spray works cannot too fast, environmental temperature cannot exorbitant (general 200C controls) , spray hind cannot undertake stoving immediately.
(After 4) assures spray shed equal time, outside maintaining the temperature with air appropriate room, the wind speed of air room cannot too big, will quicken the volatilization of solvent otherwise and shorten of coating shed equal time.
(After 5) assures spray shed smooth sex, make sure each coating has certain ply even, also cannot pass thin, too thin or heavy panel can cause orange skin appearance, suggest control of each coating ply is in 5, 30 micron left and right sides.
(The influence of 6) other element, on the high side of content of dissolvent of if coating is medium low boiling point, when construction, solvent volatilizes too fast, the material that become film has not enough time to flow to make the same score and form orange skin. Below this kind of circumstance, can adopt the measure that imposes thinner more appropriately or right amount the generation that joins dissolvent of a few high boiling point to prevent orange skin phenomenon. Itself of additional rustproof lacquer and solidify agent or thinner compatibility are bad, also can produce orange skin phenomenon.
