环氧地坪在施工過程中的註意事項包括什麼?
环氧地坪施工中需要註意哪些事項?這個問題一直困擾著不少的施工人員,下面小編通過簡短的文章給大傢簡單介紹环氧自流平地坪的施工註意事項。在环氧自流平地坪施工中,使用高壓無氣噴塗能達到比滾塗更好的表觀效果。更高的光澤度,更高的耐磨度(無氣噴塗环氧地坪漆幾乎不添加稀釋劑)。在噴塗時,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,並在地板表面平行,以免產生堆積和塗層不勻。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。
What should we pay attention to in the construction of epoxy flooring? This problem has been plagued by many workers. The following edition gives you a brief introduction to the construction of epoxy self-leveling flooring through a brief article. In the construction of epoxy self-leveling floor, high pressure airless spraying can achieve better appearance than rolling coating. Higher gloss, higher wear resistance (airless spray floor paint hardly adds diluent). When spraying, the spray gun should be perpendicular to the surface of the workpiece to be sprayed, 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. 环氧自流平地坪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、均勻的塗層。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塗。
Each spraying operation of epoxy self-leveling floor overlaps about 20-30% of the previous spraying 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.
每次噴塗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塗料堆積。
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.
相同的噴福寬度,孔徑越大,成膜越厚。
The bigger the aperture is, the thicker the film is.
相同的噴嘴孔徑,噴幅寬度越大,成膜越薄。
With the same nozzle aperture, the bigger the width of the nozzle is, the thinner the film is.
高壓無氣噴塗的註意事項
Notices for High Pressure Airless Spraying
(1)噴塗壓力和流量
(1) Spraying pressure and flow rate
對某一型號的無氣噴塗設備,當使用的塗料黏度不變、輸入的壓縮空氣壓力一定時,其噴塗壓力和流量之間的關系為:流量增大,噴塗壓力降低。當輸入的壓縮空氣的壓力升高時,噴塗壓力和流量便相應增加。
For a certain type of airless spraying equipment, the relationship between spraying pressure and flow rate is that the flow rate increases and the spraying pressure decreases when the viscosity of the coatings is constant and the input compressed air pressure is constant. When the pressure of compressed air is increased, the spraying pressure and flow rate will increase accordingly.
(2)塗料黏度與噴塗壓力
(2) Coating Viscosity and Spraying Pressure
不同類型的塗料黏度不同,高固體分塗料的黏度尤其大,比如無溶劑類高固含量的环氧自流平环氧地坪。黏度越高,施工時需要的噴塗壓力越大。一般低黏度塗料的壓力比選擇23:1、32:1,而高黏度塗料的施工壓力比一般在45:1左右。但不能一味增加噴塗的壓力,噴塗高黏度塗料時,還應考慮更換大口徑的噴嘴。
Different types of coatings have different viscosities, especially high solid coatings, such as solvent-free high solid content epoxy self-leveling floor. The higher透水地坪 the viscosity is, the higher the spraying pressure is. The pressure ratio of low viscous coatings is 23:1 and 32:1, while that of high viscous coatings is about 45:1. However, the pressure of spraying can not be increased blindly. When spraying high-viscosity coatings, the replacement of large-caliber nozzles should also be considered.
(3)噴嘴的選擇
(3) Selection of nozzles
在進行高壓無氣彩色沥清地坪噴塗前,根據所使用的塗料和噴塗對象,應選擇一定孔徑和形狀的噴嘴。噴嘴的孔徑決定瞭流量的大小,噴嘴的形狀則決定瞭噴霧的幅度。對於你那度較高、所需施工面積較大的塗料,應選擇孔徑較大的噴嘴。
Before high pressure airless spraying, nozzles with certain aperture and shape should be selected according to the coating and spraying object used. The size of the nozzle determines the size of the flow, and the shape of the nozzle determines the amplitude of the spray. For coatings with higher degree and larger construction area, nozzles with larger aperture should be selected.
