水泥仿木欄桿上色多采用高聚物乳液為主要成膜物質(常用的有聚乙酸乙烯、聚丙烯酸醋等合成樹脂液)加入顏料、助劑制成的涂料進行涂飾,具體根據隱蔽或暴露面等不同情況上色。
The cement wood like railings are mostly painted with a coating made of high polymer lotion as the main film-forming material (commonly used are synthetic resin liquids such as polyvinyl acetate and polyacrylic acid vinegar) added with pigments and additives, and the color is applied according to different conditions such as concealed or exposed surfaces.
乳液涂料
Lotion coating
乳液涂料以水為分散介質,施工方便,涂層的透氣性和耐堿性較好,利于在水泥仿木欄桿堿性基層上施涂,乳液涂料的漆膜對水泥仿木欄桿干燥度要求不高,且干燥快,可縮短施工周期。漆膜干燥后,不會因為內部水氣蒸發產生壓力而鼓泡脫落。
The lotion coating uses water as the dispersion medium, which is convenient for construction. The coating has good air permeability and alkali resistance, which is conducive to the application on the alkaline base of the cement wood like railing. The film of the lotion coating has low requirements on the dryness of the cement wood like railing, and it dries quickly, which can shorten the construction period. After the paint film is dry, it will not bubble and fall off due to the pressure generated by internal water vapor evaporation.
上色方法
Coloring method
1、基層處理:先把水泥仿木欄桿建筑基層表面殘留的邊框、浮灰、浮沙石及油脂等凈,然后用107膠加水1倍調合均勻涂刷底層,稍干后,進行下一步工序。
1. Base treatment: First, remove the remaining borders, floating ash, floating sand, and grease on the surface of the cement imitation wooden railing building base, and then use 107 glue and water to mix and evenly brush the bottom layer. After slightly drying, proceed to the next step of the process.
2、刮布涂層:把配制好的涂層材料用刮板用力將其布開,每次厚度約在0.5厘米左右。待前層涂層稍顯干燥后,即可刮涂第二層,一般刮涂2到3次即可。
2. Scraping coating: Use a scraper to forcefully spread the prepared coating material, with a thickness of approximately 0.5 centimeters each time. After the first layer of coating becomes slightly dry, the second layer can be scraped, usually 2-3 times.
3、涂層表面處理:施工涂層帶干燥后,需用0號天砂布將其磨平打光,磨后表面顏色會深淺不均,再涂刷107膠色漿一道,稍干后即涂刷2到3層氯乙烯共聚乳液。經過這種方法處理的內檐涂層,色彩均勻鮮艷、豐滿度好,富有裝飾效果,耐化學腐蝕。
3. Coating surface treatment: after the construction coating belt is dry, it needs to be polished with 0 # emery cloth. After polishing, the surface color will be uneven, and then apply 107 glue color paste. After slightly drying, apply 2 to 3 layers of vinyl chloride copolymer lotion. The interior eaves coating treated by this method has uniform and bright colors, good fullness, rich decorative effect, and chemical corrosion resistance.
大量水泥仿木欄桿案例證明,在含水量大的鋼筋混凝土水泥仿木欄桿建筑上上色,選用上述上色方法是非常成功的。此方法用于的水泥仿木欄桿工程,竣工多年經受各種地區多種氣候因素的檢驗,所有涂飾的水泥仿木欄桿建筑均很牢固、耐久、不褪色。
A large number of cases of cement imitation wooden railings have proven that the above coloring method is very successful in coloring reinforced concrete cement imitation wooden railing buildings with high water content. This method is used for the cement imitation wood railing project, which has been tested by various climatic factors in various regions for many years after completion. All painted cement imitation wood railing buildings are sturdy, durable, and non fading.
