出现流痕的原因
Reasons for flow marks
1.环境问题
1. Environmental issues
施工环境比较差，温度过低或过高；施工环境中的溶剂蒸汽含量过高；还有就是施工现场空气流通性较差。
The construction environment is relatively poor, the temperature is too low or too high; the content of solvent vapor in the construction environment is too high; and the air circulation in the construction site is poor.
2.施工问题
2. Construction problems
施工时，由于操作不当，导致环氧地坪漆在喷涂时形成流痕现象。施工人员把喷枪太靠近地面或是在挪动喷枪时，速渡过慢导致一次喷涂过厚。
During construction, the improper operation resulted in the formation of flow marks in the spraying of epoxy floor paint. When the spraying gun is too close to the ground or moving, too slow speed leads to too thick spraying at one time.
喷枪也是决定地坪质量好坏的关键因素，因此喷枪的使用要得当，例如，出漆量大的喷嘴应该配高出气量的空气孔。同样，当喷涂的幅度变小时，就应该更换出漆量小的喷嘴。
Spray gun is also a key factor to determine the quality of the floor, so the use of spray gun should be appropriate, for example, spray nozzles with large amount of paint should be equipped with air holes with high air volume. Similarly, when the spraying range becomes smaller, the nozzle with less paint should be replaced.
施工人员的技术同样是影响地坪质量的重要因素。喷涂的地坪漆一定要厚薄平均，不然较厚的涂膜比较难干容易向下流淌构成一道道流痕。
The technology of construction personnel is also an important factor affecting the quality of floor. Spraying floor paint must be uniform in thickness, otherwise the thicker film is more difficult to dry and easy to flow down to form a channel of flow marks.
3.材料问题
3. Material issues
使用环氧地坪漆与所需的稀释剂不匹配，或是掺加过量的防潮剂，材料的粘渡过低都会形成流痕。
If the epoxy floor paint does not match the required diluent, or if excessive moisture-proof agent is added, the flow marks will be formed if the adhesion of the material is too low.
