针孔，是指无锡环氧地坪漆膜表面出现的细小孔洞，有的圆柱形，也有的半圆形。针孔一方面影响无锡环氧地坪工程的美观，另一方面由于孔洞的存在会导致污染物质更容易破坏环氧地坪漆层，容易造成后续问题。针孔的大小一般为100谬到几毫米之间。下面环氧地坪漆厂家就给大家分享环氧地坪漆表面【针孔】产生的原因及预防处理办法。

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、环氧地坪漆施工后产生【针孔】的原因：

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

1、地坪漆材料施工黏度过大，施工场所温度较低，使用涂料搅拌后由于停置的时间过短，仍有残存的气泡;

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、溶剂搭配不当，低沸点挥发性溶剂用量过多，造成涂膜表面迅速干操，而底部的溶剂不宜逸出;

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。空气中有灰尘，施工地面有发汗和油污等现象;

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

4、在喷涂施工中喷枪的压力过大，喷嘴口径过小，喷枪和物面的距离太远;

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、施工场地环境温度过高，被涂物或是施工地面温度过高;

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

6、环氧树脂地坪漆涂料流平性差，释放气泡性差。

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

二、预防环氧地坪漆施工后出现【针孔】的方法：

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

1、环氧地坪漆涂料施工黏度不宜过大，施工场所温度不宜过低。涂料搅拌后，应放置一段时间，待气泡跑净后再施工;

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、注意溶剂的搭配，应控制低沸点溶剂的用量;

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

3、施工前应除涂料中的水分和空气中的灰尘，确保被涂物表面应处理干净后再进行施工;

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、应掌握好喷涂的技术;

4. The spraying technology should be mastered well.

5、注意施工场所的环境湿度，被涂物表面的温度，不应高于施工时的环境温度;

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、调整涂料配方。

6. Adjust the formulation of paint.

三、消除环氧地坪表面【针孔】的方法：

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

1、环氧地坪漆表面发生针孔的地方用砂纸机磨平;

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

2、再填补并以平刮板或镘刀抹平;

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

3、硬化后再做环氧地坪表面处理。

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