    1、旧漆膜出现粉化、失光、生锈、起泡、剥落、开裂、玷污、长霉等现象时,程度轻的可用细砂纸或洗涤剂清除失效漆膜、沉屑、污损后,可以参照弊病防止措施进行补救,重新涂装。严重的弊病,涂层已经不完整,失去保护功能的场合,则应彻底去掉涂层,重新涂装。济南自流平http://www.jndmzp.com/
    1, the old film powder, light loss, rust, blistering, peeling, cracking, stain, mildew and other phenomena, use sandpaper to remove paint, failure or detergent, cuttings settlement fouling degree of light, can refer to prevent measures to remedy the defects, re painting. Serious drawbacks, coating has been incomplete, lose the protection function of the occasion, it should be completely removed coating, re painting.
    2、旧漆膜过厚、发脆或与新设计的涂料不适应、不配套,应予以除去。
    2, the old paint film is too thick, brittle or does not adapt, and the new design of the coating is not complete, should be removed.
    3、将旧漆膜除去失效部分,直到完好、坚硬、附着良好的漆膜,其下不得有锈或起泡,与底材附着力很高,不能被插入其底下的钝的刀片起层。漆膜表面需除尘、油和其他附着污物。
    3, the old paint removing failure part, until it snaps, hard, good adhesion of the film, no rust or foaming, and substrate adhesion is very high, can not be inserted into the bottom of the blunt blade layer. The film surface dust, oil and other dirt.
    4、留在区域边缘准备再涂得牢固附着的漆膜必须加工成羽状,以使再涂装表面具有光滑的外观。为了增强与新涂料的附着强度,一般可将旧漆膜打毛处理。
    4, in the edge of the region to apply securely attached to the film must be processed into pinnate, so that coating surface with smooth appearance. In order to enhance the adhesion strength of coating and the new, the general can be old film roughening treatment.
    5、进行再涂装所用的涂料一般好与初涂覆所用的涂料相同。可在旧漆膜上涂覆符合配套原则的其他品种涂料,但须预先在局部作实验。如环氧做底漆,可在其上涂装各种品种的涂料,但为防止附着力不佳,可加涂“过渡层”等。
    5, the coating used in the paint and coatings are usually best first coated the same. Other varieties of paint can be coated with matching principle in the old paint film, but subject to the prior experiment in local. Such as epoxy primer can be done, in the coating of all varieties of paint, but to prevent the adhesion is poor, can apply the "transition layer".
