“…Hal ini dapat menghasilkan ketidakseragaman ketebalan lapisan, titik-titik kosong, atau bahkan mengganggu proses aplikasi powder coating secara keseluruhan (Ahmad and Ajer, 2015). Sementara itu, variasi ukuran mesh powder juga dapat memengaruhi kualitas lapisan, karena partikel powder yang terlalu halus atau terlalu kasar dapat menghasilkan lapisan yang tidak merata atau kasar (Claase, Vercoulen and Misev, 2014).…”

Penelitian ini bertujuan untuk merancang alat gun powder coating yang lebih baik dengan kemiringan tangki penyimpanan powder dan penambahan saringan mesh yang dapat dilepas pasang. Desain tersebut mengatasi masalah distribusi yang tidak merata dan variasi ukuran mesh powder pada proses pelapisan bubuk. Hasil penelitian menunjukkan bahwa desain dengan kemiringan tangki memungkinkan aliran yang lancar dan terkontrol, efisiensi penggunaan powder coating yang lebih baik, kemudahan pengisian ulang, penyemprotan yang merata, pengurangan powder coating pada hasil akhir, dan kontrol yang lebih baik terhadap aliran powder. Penambahan saringan mesh membantu menghilangkan partikel yang lebih besar atau gumpalan pada bubuk coating serta menjaga kualitas bubuk coating dari kontaminasi. Desain inovatif ini dapat meningkatkan kualitas dan konsistensi lapisan powder coating yang dihasilkan.

The particle size of powder coatings is an important factor affecting flow and fluidization performance, which in turn determines the quality of the coating. Powder coating particles, such as boron nitride, titanium dioxide, barium titanate, niobium oxide, and tungsten oxide, can be seen in SEM images as circular or polygonal shapes, with irregular edges and sizes, as well as aggregation and stacking between them. This paper introduces a novel method of automatic particle identification and size analysis applied in SEM images for the investigation of coating quality. Firstly, a fast gradient segmentation algorithm (Split–Merge) is utilized to automatically generate samples through determining the adhesive particles and particle groups. The samples are then manually checked and corrected to further segment the particles in order to form the dataset. Finally, the YOLOv5, a mature target detection algorithm, is used to train the labeled data in order to produce a multi-target detection recognition model. The model can be applied to identify more pictures of the same substance, and the particles’ long and short axes are estimated using the elliptical coverage of the particles within the identified image boundary box. Experiment results from four kinds of powders suggest that this method can provide automatic particle size analysis for industrial SEM particle images.
