      水泥地板漆表面出現【針孔】現象該怎么辦?

      東柏地坪漆 2019-03-30 4534 0

      針孔,是指水泥地板漆漆膜表面出現的細小孔洞,有的圓柱形,也有的半圓形。針孔一方面影響水泥地板漆工程的美觀,另一方面由于孔洞的存在會導致污染物質更容易破壞水泥地板漆層,容易造成后續問題。針孔的大小一般為100謬到幾毫米之間。下面水泥地板漆廠家就給大家分享水泥地板漆表面【針孔】產生的原因及預防處理辦法。

      Pinholes refer to small holes on the surface of epoxy floor paint film, some cylindrical and some semicircular. On the one hand, pinholes affect the aesthetics of floor paint engineering, on the other hand, because of the existence of holes, pollutants are more likely to damage the floor paint layer, and easy to cause follow-up problems. The size of the pinhole is usually between 100 and several millimeters. The following epoxy floor paint manufacturers will share with you the causes of the surface [pinholes] of epoxy floor paint and the preventive measures. 一、水泥地板漆施工后產生【針孔】的原因:

      1. Reasons for pinholes in epoxy floor paint after construction:

      1、地坪漆材料施工黏度過大,施工場所溫度較低,使用涂料攪拌后由于停置的時間過短,仍有殘存的氣泡;

      1. The construction viscosity of floor paint material is too high and the temperature of construction site is low. After mixing with paint, there are still residual bubbles due to the short time of stopping.

      2、溶劑搭配不當,低沸點揮發性溶劑用量過多,造成涂膜表面迅速干操,而底部的溶劑不宜逸出;

      2. The improper matching of solvents and excessive use of volatile solvents at low boiling point result in rapid drying on the surface of the film, while the solvent at the bottom should not escape.

      3、地坪漆涂料中有水分??諝庵杏谢覊m,施工地面有發汗和油污等現象;

      3. There is moisture in floor paint. There are dust in the air, sweating and oil pollution on the construction ground.

      4、在噴涂施工中噴槍的壓力過大,噴嘴口徑過小,噴槍和物面的距離太遠;

      4. In spraying construction, the pressure of spraying gun is too large, the diameter of spraying nozzle is too small, and the distance between spraying gun and object surface is too far.

      5、施工場地環境溫度過高,被涂物或是施工地面溫度過高;

      5. The ambient temperature of construction site is too high, and the temperature of coating or construction ground is too high.

      6、環氧樹脂地坪漆涂料流平性差,釋放氣泡性差。

      6. Epoxy floor paint has poor leveling property and poor releasing bubbles.

      二、預防水泥地板漆施工后出現【針孔】的方法:

      2. Measures to prevent pinholes from appearing after construction of epoxy floor paint:

      1、水泥地板漆涂料施工黏度不宜過大,施工場所溫度不宜過低。涂料攪拌后,應放置一段時間,待氣泡跑凈后再施工;

      1. The construction viscosity of epoxy floor paint should not be too high and the temperature of construction site should not be too low. After mixing the paint, it should be placed for a period of time, and then constructed after the air bubbles run away.

      2、注意溶劑的搭配,應控制低沸點溶劑的用量;

      2. Attention should be paid to the mixing of solvents and the amount of solvents with low boiling point should be controlled.

      3、施工前應除涂料中的水分和空氣中的灰塵,確保被涂物表面應處理干凈后再進行施工;

      3. Moisture and dust in the paint should be removed before construction to ensure that the surface of the coated material should be treated clean before construction.

      4、應掌握好噴涂的技術;

      4. The spraying technology should be mastered well.

      5、注意施工場所的環境濕度,被涂物表面的溫度,不應高于施工時的環境溫度;

      5. Attention should be paid to the environmental humidity of the construction site and the temperature of the surface of the coating should not be higher than that of the environment at the time of construction.

      6、調整涂料配方。

      6. Adjust the formulation of paint.


      三、消除環氧地坪表面【針孔】的方法:

      3. The methods of eliminating pinholes on the surface of epoxy flooring:

      1、水泥地板漆表面發生針孔的地方用砂紙機磨平;

      1. Where pinholes occur on the surface of epoxy floor paint, they are ground by sandpaper machine.

      2、再填補并以平刮板或鏝刀抹平;

      2. Fill it up again and smooth it with a flat scraper or trowel.

      3、硬化后再做環氧地坪表面處理。

      3. After hardening, surface treatment of epoxy floor is done.
