环氧地坪漆施工過程中如何控制漆膜厚度

在施工質量管理中，膜厚管理是較為重要的一項。所謂膜厚管理，是對环氧地坪漆施工中的塗膜厚度進行控制和對施工後的膜厚進行檢測分析、判別和質量反饋與處理的過程。膜厚管理的目的是使环氧地坪塗層的厚度既要滿足設計規定的厚度以確保防護性能，又要避免超厚帶來的浪費。环氧地坪塗裝對於膜厚管理各個項M有明確的要求，例如在塗裝工藝設計上，對每道應達到的厚膜和總幹膜厚度都有嚴格的規定，應按要求執行。
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 epoxy floor paint, testing and analyzing the film thickness after construction, distinguishing and quality feedback and treatment. The purpose of film thickness management is to make the thickness of epoxy floor coatings meet the design requirements to ensure protection performance, but also to avoid waste caused by excessive thickness.
Epoxy floor coating has clear requirements for each item M of film thickness management. For example, in the design of coating process, there are strict requirements for the thickness of thick film and dry film to be achieved in each line, and they should be implemented according to requirements.
膜厚管理包括濕膜厚度檢測和幹膜厚度檢測。濕膜厚度一般在塗裝過程中，在每一道塗料塗刷完成時進行及時檢測。幹膜厚度可在施工過程中檢測，但在施工完畢後必須進行總幹膜厚度的檢驗。
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．濕膜厚度的檢驗
1. wet film thickness test
濕膜厚度測定一般是塗覆者用於指導施工人員確定獲得預期幹膜厚度需要塗覆的規定塗料用量。濕膜測厚儀常用的有兩種：濕膜厚度輪規和濕膜厚度梳規。濕膜厚度的檢測方法和技巧見有關書籍介紹。采用濕膜厚度測厚儀的優點在於可以在塗覆過程中檢查和改正不適當的塗膜厚度。如果施工人員知道瞭濕膜厚度，當以此數據乘以塗料固體分的體積百分率，就可估算出幹膜厚度，或者施工人員也可以通過小面積施工的塗料用量，結合產品說明書的推薦數據估算出幹膜厚度。
Wet film thickness measurement is generally used by the coater to gu透水地坪ide 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.
實際中進行破壞性試驗後較難修復，所以濕膜厚度的測定和每道塗裝厚度的累加以及塗料用量的控制(比如無溶劑自流平环氧地坪塗料的施工)往往可用於取代總幹膜厚度測定。
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．幹膜厚度的檢測

測定幹膜厚度的重要性在於保證塗覆達到規定的厚度，避免由於不適當的厚度導致塗層的過早失效，對於环氧地坪塗裝尤其如此。幹膜厚度的測量必須在塗膜完全幹燥後，采用幹膜測厚儀進行測定。
The importance of measuring the thickness of dry film is to ensure that the coating reaches the speci环氧地坪fied 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.
常用於地坪的幹膜厚度檢測儀器有破壞性測厚儀和卡尺。檢測時，測量點的選擇要註意代表性。由於檢測是破壞性的，一般隻能在邊角等不影響外觀的地方取樣和檢查。對於塗膜厚度的要求一般如下：所有厚度測定點的平均值不應低於規定幹膜厚度的90％；未達到規定幹膜厚度的測定點數目不應超過測定點總數的10％。未達到規定厚度者應進行如下處理：合格率低於80％，需全面補塗；合格率為80％-90％，應根據情況做局部補塗。許多塗層膜厚超過規定標準，一般都不成問題，但帶來瞭塗料的過多損耗和塗裝經費的增加。由於塗層過厚會影響溶劑的揮發和完全幹燥，以及下一塗層的固化，過厚的塗膜還可能產生起皺或龜裂等缺陷，應予以註意。施工中當膜厚超過規定最大幹膜厚度的10％時，應設法解決。
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.
