高壓無氣噴涂也叫做無氣噴涂,是采用高壓泵使環氧地坪漆涂料增壓到高壓,使南京環氧地坪材料形成霧狀,然后經噴嘴的小孔噴出,將涂料涂于工件表面的一種涂裝方法。環氧地坪漆使用高壓無氣噴涂的優點:環氧地坪漆施工中,使用高壓無氣噴涂能達到比滾涂更好的表觀效果。更高的光澤度,更高的耐磨度(無氣噴涂環氧地坪漆幾乎不添加稀釋劑)。環氧地坪漆使用高壓無氣噴涂施工方法:
High-pressure airless spraying, also known as airless spraying, is a coating method that uses a high-pressure pump to pressurize the floor paint to high pressure, so that the floor material forms a fog, and then sprays out through a small hole in the nozzle to coat the surface of the workpiece. The advantages of using high pressure airless spraying for epoxy floor paint are as follows: in the construction of epoxy floor paint, using high pressure airless spraying can achieve better appearance than rolling coating. Higher gloss, higher wear resistance (airless spray floor paint hardly adds diluent). High pressure airless spraying method is used for floor paint construction.
1、環氧地坪漆噴涂施工時,噴槍應與被噴工件表面垂直,距離表面30-40cm。噴槍應以合適的速率均勻移動,并在地板表面平行,以免產生堆積和涂層不勻。噴槍與物面的噴射距離和垂直角度由身體控制,噴槍的移動同樣要用身體來協助臂膀的移動,不可移動手腕,但手腕要靈活。
1. When spraying epoxy floor paint, the spray gun should be perpendicular to the surface of the sprayed workpiece, 30-40 cm away from the surface. The spray gun should move evenly at an appropriate rate and parallel to the floor surface to avoid accumulation and uneven coating. The spray distance and vertical angle between the spray gun and the object surface are controlled by the body. The movement of the spray gun should also be assisted by the body to move the arm, not the wrist, but the wrist should be flexible.2、每一道噴漆作業就在前一道噴漆作業上搭接約20~30%,以便獲得完整、均勻的涂層。噴拐角時,噴槍可對準拐角的中心,以確保兩側能得到均勻的噴涂。
2. Each painting operation laps about 20-30% on the previous painting operation in order to obtain a complete and uniform coating. When spraying corners, the spray gun can aim at the center of the corners to ensure uniform spraying on both sides.3、每次噴涂時應在噴槍移動時開啟噴槍扳機,同樣也應在噴槍移動時關閉噴槍扳機,如此可避免造成在表面過多的涂料堆積。
3. When spraying, the spray gun trigger should be opened when the spray gun moves, and the spray gun trigger should also be closed when the spray gun moves, so as to avoid excessive coating accumulation on the surface.4、相同的噴福寬度,孔徑越大,成膜越厚。相同的噴嘴孔徑,噴幅寬度越大,成膜越薄。
4. The bigger the aperture is, the thicker the film is. With the same nozzle aperture, the bigger the width of the nozzle is, the thinner the film is.
環氧地坪漆使用高壓無氣噴涂施工注意事項:
Attentions for high pressure airless spraying construction of floor paint:
1、噴涂壓力和流量。壓力與流量是成反比的,流量越大,壓力越小。當輸入的壓縮空氣的壓力升高時,噴涂壓力和流量也要相應增加。
1. Spraying pressure and flow rate. Pressure and flow rate are inversely proportional. The larger the flow rate, the smaller the pressure. When the pressure of compressed air is increased, the spraying pressure and flow rate will increase accordingly.2、噴嘴的選擇。不同的涂料和噴涂物所使用的噴嘴也是不同的,噴嘴口徑決定了流量的大小,形狀則決定噴霧的幅度。所以對于年度較高,施工面積較大的涂料,就應該選擇孔徑較大的噴嘴。
2. Selection of nozzles. Different coatings and sprays also use different nozzles. The caliber of the nozzle determines the size of the flow, and the shape determines the amplitude of the spray. Therefore, for coatings with higher annual and larger construction area, the nozzle with larger aperture should be selected.3、地坪漆涂料粘度與噴涂壓力。不同類型的涂料粘度就不同,特別市高固體分涂料粘度很大。對于粘度較高的涂料,施工時需要的噴涂壓力就會比較大。
3. Viscosity and spraying pressure of floor paint. Different types of coatings have different viscosities, especially high solid coatings. For coatings with high viscosity, the spraying pressure required during construction will be relatively high.
