“…According to these standards, the appropriate thickness is in the range of 2 bar / 15 cm. These results are similar to the research by Dzikriansyah and Rasyid et al, that the larger the air pressure and the smaller the nozzle distance to the panel results in the coating will have a significant thickness compared to the small air pressure and nozzle distance to the large panel (Dzikriansyah, 2017;Rasyid, Santoso and Utama, 2017).…”

“…As a result, it takes longer for the paint droplets to reach the surface of the specimen, which reduces the hiding power of the paint. Poor paint atomization results in an orange peel effect, which also results in low gloss (Rasyid, Santoso and Utama, 2017).…”

“…Dzikriansyah and Rasyid et al, conducted a study that demonstrated the impact of air pressure and nozzle distance on coating thickness (Dzikriansyah, 2017;Rasyid, Santoso and Utama, 2017). Similarly, Wirojanupatump et al, explained that higher air pressure can increase droplet velocity, leading to an increase in the number of droplets reaching the substrate surface and, consequently, an increase in coating thickness (Wirojanupatump, Jiansirisomboon and Sopadang, 2006).…”

Environmental influences can cause corrosion or damage to materials, which is why paint coating is used to protect them. Some of the factors that affect the quality of the paint are technical, such as setting the air pressure and spray gun nozzle spacing. The experimental research aims to determine how air pressures of 1.5, 2, and 2.5 bar and nozzle spacings of 10–15–20 cm affect the gloss and thickness of the water-based paint layer. A gravity-feed spray gun was used for this purpose. The luster test method uses an AMTAST AMN60 glossmeter with the ASTM D523-08 standard, and the thickness test uses a coating thickness gauge with the ASTM E 376-96 standard. The air pressure and the distance of the spray gun nozzle affect the gloss and thickness of the paint layer. Parameter 2 bar/15 cm yielded the highest gloss of 92.77 GU, while parameter 2.5 bar/10 cm resulted in the highest coating thickness of 0.26 mm.

“…Coating was applied using a spray gun type F75 tube with a 400-cc capacity and a typical nozzle size of 1.5 mm to 2.0 mm. The spraying process used to obtain the desired thickness was described in Rasyid et al [31]. The spraying distance was approximately 100 mm, the spray gun pressure was 0.0827 MPa, the residual tube pressure was 0.1378 MPa, and the target thickness was 0.1 mm.…”

Using bamboo particle board as a wall divider, a furniture component, or an automotive component with a sound absorber function may be a viable option for architects and engineers seeking to achieve desired acoustical qualities, including noise reduction. However, there is still a dearth of research on the effect of particle board finishing and coatings on acoustical sound absorption and noise reduction qualities. This study, therefore, aims to determine the surface characteristics and acoustical properties of bamboo particle board, coated with polyurethane (PU). The single-layer homogeneous particle boards were constructed using particles classified as fine and coarse with two different board densities, and coated with a high-quality PU lacquer. This study found that the coating treatment of 0.3 mm 0.6 mm succeeded to significantly decrease surface roughness, as well as thickness, swelling, and water absorption, with the thickness coating as a dominant factor compared with board density and board particle size. Adding a PU coating increases sound absorption performance at low frequencies, but significantly reduces acoustical properties at high frequencies. The increase of particle board density leads to the decrease in noise reduction coefficient capability. Results obtained from this study are useful to determine the optimal coating thickness in terms of evaluating acoustical panel products.

“…Sand-blasting ini merupakan proses dimana penyemprotan menggunakan partikel dengan tekanan bervariasi (Kusumawijaya et al, 2019). Proses pengecetan tabung merupakan proses dimana lapisan yang sudah di sand-blasting lalu dilakukan pengecetan, khusus tabung LPG bright gas ini dilakukan pengecetan tabung 2 kali dengan pemilihan parameter menggunakan alat yaitu spray gun (Rasyid et al, 2017). Didalam surat perjanjian Nomor SPJ-332/F12400/2016-S3, Agen dan Pertamina mempunyai hak dan kewajiban untuk melaksanakan kegiatan pemeliharaan tabung sesuai ketentuan yang berlaku, dan Pertamina wajib melakukan pengawasan demi terjadinya kesinambungan yang berguna untuk memuaskan konsumen agar kualitas pengecetan tabung sesuai dengan standar Pertamina (Kusnadi et al, 2020).…”

Kebutuhan pokok rumah tangga sangat penting, kebetuhan tersebut ialah gas elpiji sebagai sumber kehidupan untuk masyarakat maupun industri. Penelitian ini bertujuan untuk menganalisis perbandingan ketebalan cat antara tabung gas 5,5 kg dengan tabung gas 12 kg,untuk mengetahui efektivitas ketebalan cat yang ada di dalam tabung gas 5,5 kg dengan 12 kg sesuai standar Pertamina.Penelitian ini menggunakan desain eksperimen. Penelitian eksperimen ini mengamati ketebalan cat tabung gas 5,5 kg dan tabung 12 kg yang dimana penelitian merupakan hasil pengumpulan data observasi pada 2 tabung gas. Sampel ketebalan pengecetan dilakukan secara acak dengan mengambil 10 tabung gas gas 5,5 kg dan 10 tabung gas 12kg. Teknik analisis data bersifat deskriptif kuantitatif yaitu menganalisis data dengan mendeskripsikan atau menjelaskan data yang diperoleh dengan menggunakan manual book pemeliharaan tabung gas. Hasil penelitian menunjukan adanya pengaruh dari variasi Ketebalan cat tabung gas 5,5 kg memiliki rata-rata perbandingan 53,6 micron. Sedangkan perbandingan ketebalan cat tabung gas 12 kg memiliki rata-rata perbandingan 53, 8 micron melebihi standar yang ada di manual book yaitu 50> micron. Karena dalam proses pengumpulan data terjadi beberapa faktor yang menyebabkan ketebalan cat itu tidak stabil maka dari itu harus teliti ketebalan cat apakah sudah sesuai dengan kaidah manual book Pertamina, sudah melewati atau tercapai nya standarisasi.
