      鋁板涂裝的好壞跟什么有關系呢?

      涂裝是鋁板制造中比較重要的工序,涂裝質量的優劣,直接影響了鋁板的裝飾效果.造成鋁板涂裝優劣的因素主要有四點,下面就讓我們鋁板廠家來帶大家了解一下這方面的內容吧.對這方面感興趣的朋友一定不能錯過.
      Coating is an important process in aluminum plate manufacturing. The quality of coating directly affects the decorative effect of aluminum plate. There are four main factors causing the quality of aluminum plate coating. Let's take you to know about this content. Friends interested in this aspect must not miss it
      1.環境。要求涂裝室內部清潔干凈,做到防塵、防蟲和一定的通風性能,保證鋁板涂裝表面質量不受污染.同時由于氣溫變化而及時更改工藝條件.
      1. Environment. The interior of the coating room shall be clean, dustproof, insect proof and certain ventilation performance shall be achieved to ensure that the surface quality of aluminum plate coating is not polluted. At the same time, the process conditions shall be changed in time due to the change of air temperature
      2.原材料。涂料和鋁板是涂裝過程中能影響涂裝質量的因素,由于涂料的批次之間存在色差,涂料細度不夠而涂覆率不高,涂料與溶劑配合不佳、分層等等會直接影響涂裝效果而產生缺陷'鋁卷基材的不平整、膜厚不均勻、邊部撓曲度不佳等也直接影響產品質量和整體使用.因此,在選擇原材料時,應嚴格控制.


      2. Raw materials. Coating and aluminum plate are the factors that can affect the coating quality in the coating process. Due to the color difference between coating batches, insufficient coating fineness and low coating rate, poor coordination between coating and solvent, delamination, etc., they will directly affect the coating effect and produce defects' uneven aluminum coil substrate, uneven film thickness Poor edge deflection also directly affects the product quality and overall use. Therefore, the selection of raw materials should be strictly controlled
      3.設備。涂裝線要求涂裝設備完好,涂裝設備要求運轉平穩,不能有橫、縱向抖動,涂裝輥要求研磨細膩.涂裝機所有輥子橫向跳動,一定控制在允許范圍內,否則將嚴重影響涂層表面質量.
      3. Equipment. The coating line requires the coating equipment to be in good condition. The coating equipment shall operate stably without horizontal and vertical jitter. The coating roller shall be ground finely. The lateral runout of all rollers of the coating machine must be controlled within the allowable range, otherwise the coating surface quality will be seriously affected
      4.工藝。涂裝工藝對涂裝的質量關系密切,要求對涂裝輥、提漆輥、計量輥和基材相對線速比率控制在一定的范圍內.要根據不同的體系和涂裝產品的膜厚,對涂料設定一定的粘度范圍,保證涂裝順利進行,促進產品質量的提高.涂料的固化工藝,烘箱控制必須按要求控制,不得任意變動,否則將嚴重影響涂裝產品的色差和性能.
      4. Process. The coating process is closely related to the coating quality. It is required to control the relative linear speed ratio of coating roller, paint lifting roller, metering roller and substrate within a certain range. A certain viscosity range shall be set for the coating according to different systems and film thickness of coating products to ensure smooth coating and promote the improvement of product quality. The curing process of coating and oven control must be controlled as required, It shall not be changed arbitrarily, otherwise the color difference and performance of coating products will be seriously affected
