              保定環氧地坪施工過程中涂面漆厚度如何把控

              2021-10-22

              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,是對保定環氧地坪漆施工中的涂膜厚度進行控制和對施工后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保定環氧地坪涂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。

              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.

              保定環氧地坪涂裝對于膜厚管理各個項目有明確的要求,例如在涂裝工藝設計上,對每道應達到的厚膜和總干膜厚度都有嚴格的規定,應按要求執行。

              Epoxy floor coating for film thickness management of each project has a clear requirement, for example, in the coating process design, each should reach the thick film and total dry film thickness are strictly regulated, should be implemented according to the requirements.

              膜厚管理包括濕膜厚度檢測和干膜厚度檢測。濕膜厚度一般在涂裝過程中,在每一道涂料涂刷完成時進行及時檢測。干膜厚度可在施工過程中檢測,但在施工完畢后必須進行總干膜厚度的檢驗。

              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. Test of wet film thickness

              濕膜厚度測定一般是涂覆者用于指導施工人員確定獲得預期干膜厚度需要涂覆的規定涂料用量。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于可以在涂覆過程中檢查和改正不適當的涂膜厚度。如果施工人員知道了濕膜厚度,當以此數據乘以涂料固體分的體積百分率,就可估算出干膜厚度,或者施工人員也可以通過小面積施工的涂料用量,結合產品說明書的推薦數據估算出干膜厚度。

              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.

              實際中進行破壞性試驗后較難修復,所以濕膜厚度的測定和每道涂裝厚度的累加以及涂料用量的控制(比如無溶劑自流平地坪涂料的施工)往往可用于取代總干膜厚度測定。

              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 replac the determination of total dry film thickness.

              2、干膜厚度的檢測

              2. Measurement of dry film thickness

              測定干膜厚度的重要性在于保證涂覆達到規定的厚度,避免由于不適當的厚度導致涂層的過早失效,對于地坪涂裝尤其如此。干膜厚度的測量必須在涂膜完全干燥后,采用干膜測厚儀進行測定。

              The importance of measuring the thickness of dry film is to ensure that the coating reaches the 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檢測儀器有破壞性測厚儀和卡尺。檢測時,測量點的選擇要注意代表性。由于檢測是破壞性的,一般只能在邊角等不影響外觀的地方取樣和檢查。對于涂膜厚度的要求一般如下:所有厚度測定點的平均值不應低于規定干膜厚度的90%;未達到規定干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:合格率低于80%,需全面補涂;合格率為80%-90%,應根據情況做局部補涂。許多涂層膜厚超過規定標準,一般都不成問題,但帶來了涂料的過多損耗和涂裝經費的增加。由于涂層過厚會影響溶劑的揮發和完全干燥,以及下一涂層的固化,過厚的涂膜還可能產生起皺或龜裂等缺陷,應予以注意。施工中當膜厚超過規定最大干膜厚度的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.
