环氧地坪漆完工後會經常出現哪些問題
环氧樹脂地坪漆有著防腐蝕、耐磨損、防滑、污染小及裝飾性強等特點,在工業环氧地坪及环境要求場所所得到瞭大量采用,由於施工質量和环境因素的影響導致產生一些質量問題:a、滲色問題,滲色是指當一種顏色底漆塗膜上覆蓋另一種顏色的面漆時,會讓表面塗膜出現變色的情況,主要原因有以下幾點:底漆並沒有完全幹燥、底漆和面漆顏色上有色差、漆中含有雜色物質。
Epoxy floor paint has the characteristics of anti-corrosion, wear resistance, anti-skid, little pollution and strong decoration. It has been widely used in industrial epoxy floor and environmental requirements. Due to the influence of construction quality and environmental factors, some quality problems have arisen: a. Colouring problem. Colouring refers to when a color primer film is applied. There are several main reasons for discoloration of the surface coating when topcoated with another color: the primer is not completely dry, the color difference between the primer and the topcoat, and the paint contains彩色沥清地坪 variegated substances. b、起皺、針眼、魚眼。
B, wrinkle, needle eye, fish eye.
c、漆面較花,是指塗膜表面色彩不夠均勻,有斑紋及顏色雜亂的現象,原因是由於施工過程中,塗臉的配料不當及塗抹不均勻所致。
C. Paint more beautiful, refers to the surface of the film color is not uniform, there are spots and color disorder, the reason is due to the construction process, the face of the ingredients improper and uneven application.
d、表面泛白,是指施工作業完成後,地表塗層的塗抹出現泛白現象,原因有幾點:空氣中的濕度過高、塗面幹燥過程使用瞭過多的快幹劑。塗膜表層出現起皺現象,主要原因是漆面內外層幹燥速度不一致造成表層收攏起皮、針眼是因為溶劑發揮太快,漆液補充不及時造成的、魚眼是因為塗料或外界的雜質混入造成塗料附著力不均勻。
D, surface whitening, refers to the completion of construction operations, surface coating of the phenomenon of whitening, there are several reasons: excessive humidity in the air, the drying process of the coating used too much fast drying agent. The main reason for wrinkling on the surface of the coating is that the drying speed of the inner and outer layers of the coating is not uniform, which causes the surface to fold up, and the needle hole is caused by the solvent exerting too fast, the lacquer liquid supplementing is not timely, and the fish eye is caused by the mixture of the coating or the external impurities, which leads to the uneven adhesion of the coating.
e、粗糙、開裂問題,粗糙現象是指表層有大小不同的顆粒狀物質出現,主要原因是塗料中含有不易溶解的雜質及外界灰塵所致。地表開裂現象是因為原材料和施工質量問題,導致漆層附著力下降,在外界作用力影響下,出現掉皮開裂現象。
E. Roughness and cracking. Roughness refers to the appearance of granular substances of different sizes on the s环氧地坪urface. The main reason is that the coatings contain insoluble impurities and external dust. Surface cracking is caused by the quality problems of raw materials and construction, resulting in a decrease in the adhesion of the paint layer, under the influence of external forces, the phenomenon of peeling cracking.
