    环氧地坪漆施工过程中漆膜厚度控制的方法

    在施工质量管理中,膜厚管理是较为重要的一项。所谓膜厚管理,是对环氧地坪漆施工中的涂膜厚度进行控制和对施工后的膜厚进行检测分析、判别和质量反馈与处理的过程。膜厚管理的目的是使环氧地坪涂层的厚度既要满足设计规定的厚度以确保防护性能,又要避免超厚带来的浪费。地坪涂装对于膜厚管理各个项M有明确的要求,例如在涂装工艺设计上,对每道应达到的厚膜和总干膜厚度都有严格的规定,应按要求执行。

    In the construction quality management, the film thickness management is a more important item. The so-called film thickness management is the process of controlling the film thickness in the construction of floor paint, detecting and analyzing the film thickness after construction, distinguishing and quality feedback and treatment. The purpose of film thickness management is to ensure that the thickness of floor coatings not only meets the design requirements to ensure protection performance, but also to avoid waste caused by excessive thickness. Floor coating for film thickness management of each M has a clear requirement, for example, in the painting process design, each should be reached to the thick film and total dry film thickness are strictly regulated, should be carried out according to the requirements. 膜厚管理包括湿膜厚度检测和干膜厚度检测。湿膜厚度一般在涂装过程中,在每一道涂料涂刷完成时进行及时检测。干膜厚度可在施工过程中检测,但在施工完毕后必须进行总干膜厚度的检验。

    Film thickness management includes wet film thickness measurement and dry film thickness detection. Wet film thickness is usually detected in the coating process, when each painting is completed. Dry film thickness can be measured during construction, but the total dry film thickness must be checked after construction.

    1.湿膜厚度的检验

    1. wet film thickness test

    湿膜厚度测定一般是涂覆者用于指导施工人员确定获得预期干膜厚度需要涂覆的规定涂料用量。湿膜测厚仪常用的有两种:湿膜厚度轮规和湿膜厚度梳规。湿膜厚度的检测方法和技巧见有关书籍介绍。采用湿膜厚度测厚仪的优点在于可以在涂覆过程中检查和改正不适当的涂膜厚度。如果施工人员知道了湿膜厚度,当以此数据乘以涂料固体分的体积百分率,就可估算出干膜厚度,或者施工人员也可以通过小面积施工的涂料用量,结合产品说明书的推荐数据估算出干膜厚度。

    Wet film thickness measurement is generally used by the coater to guide the construction staff to determine the expected dry film thickness required to coat the specified amount of paint. There are two kinds of wet film thickness gauge: wet film thickness gauge and wet film thickness comb gauge. The methods and techniques of wet film thickness are introduced. The advantage of the wet film thickness gauge is that it can check and correct the improper film thickness during the coating process. If the builder knows the wet film thickness, the dry film thickness can be estimated by multiplying this data by the volume percentage of the solid content of the paint. Or the builder can estimate the dry film thickness by the amount of paint used in small area construction and combining the recommended data in the product specification.

    实际中进行破坏性试验后较难修复,所以湿膜厚度的测定和每道涂装厚度的累加以及涂料用量的控制(比如无溶剂自流平地坪涂料的施工)往往可用于取代总干膜厚度测定。

    It is difficult to repair after destructive test in practice, so the determination of wet film thickness and the cumulative thickness of each coating and the control of coating dosage (such as the construction of solvent-free self-leveling floor coating) can often be used to replace the determination of total dry film thickness.

    2.干膜厚度的检测

    2. detection of dry film thickness

    测定干膜厚度的重要性在于保证涂覆达到规定的厚度,避免由于不适当的厚度导致涂层的过早失效,对于地坪涂装尤其如此。干膜厚度的测量必须在涂膜完全干燥后,采用干膜测厚仪进行测定。

    The importance of measuring the thickness of dry film is to ensure that the coating reaches the specified thickness and avoid premature failure of the coating due to inappropriate thickness, especially for floor coating. The measurement of dry film thickness must be made by dry film thickness gauge after the film is completely dried.

    常用于地坪的干膜厚度检测仪器有破坏性测厚仪和卡尺。检测时,测量点的选择要注意代表性。由于检测是破坏性的,一般只能在边角等不影响外观的地方取样和检查。对于涂膜厚度的要求一般如下:所有厚度测定点的平均值不应低于规定干膜厚度的90%;未达到规定干膜厚度的测定点数目不应超过测定点总数的10%。未达到规定厚度者应进行如下处理:合格率低于80%,需全面补涂;合格率为80%-90%,应根据情况做局部补涂。许多涂层膜厚超过规定标准,一般都不成问题,但带来了涂料的过多损耗和涂装经费的增加。由于涂层过厚会影响溶剂的挥发和完全干燥,以及下一涂层的固化,过厚的涂膜还可能产生起皱或龟裂等缺陷,应予以注意。施工中当膜厚超过规定最大干膜厚度的10%时,应设法解决。

    There are destructive thickness gauge and caliper commonly used in the dry film thickness measuring instrument. When testing, the choice of measuring points should be noted for representativeness. Since testing is destructive, sampling and inspection can only be done at corners and without affecting the appearance. The requirements for film thickness are generally as follows: the average value of all test points should not be lower than 90% of the specified dry film thickness; the number of test points that do not reach the specified dry film thickness should not exceed 10% of the total number of test points. Those who have not reached the prescribed thickness should be treated as follows: the qualified rate is less than 80%, which needs to be repaired completely; the qualified rate is 80% - 90%, which should be repaired locally according to the situation. Many coatings exceed the prescribed standards, generally not a problem, but has brought excessive loss of coatings and the increase in the cost of coating. Due to excessive thickness of the coating will affect the volatilization of the solvent and completely dry, as well as the solidification of the next coating, excessive thickness of the coating may also produce wrinkles or cracks and other defects, it should be noted. When the thickness of the membrane exceeds 10% of the maximum dry film thickness, we should try to solve it.
