Corona discharge surface treatment device (manufactured by Wedge)
Asakusa Manufacturing Co., Ltd. manufactures specialized equipment using corona discharge surface treatment devices (made by Wedge). Please feel free to consult us regarding corona discharge surface treatment devices and specialized equipment.
Substrate treatment tests and test equipment rentals available! Surface treatment can be performed using corona discharge without applying heat to the substrate, enhancing hydrophilicity.
Wedge's corona discharge surface treatment device generates corona discharge in the atmosphere to modify the surface of substrates. Even substrates with low polar groups, such as films and non-woven fabrics, can have improved hydrophilicity and enhanced functions such as adhesion, coating properties, and printability by irradiating with corona discharge. Surface treatment can be performed without applying heat to the substrate, unlike flame treatment. 【Enhanced substrate surface functions】 - Printability / Hydrophilicity / Adhesion / Coating properties / Tackiness / Water absorption / Adhesion / Wettability *For more details, please contact us or download and view the catalog.
The non-woven fabric is hydrophilized through a dry process to impart water absorption properties.
By irradiating a substrate with a low density of polar groups with corona discharge electrons in the atmosphere, polar groups are generated. As a result, the substrate's hydrophilicity is enhanced, imparting functions such as water absorption, adhesion, and coating properties. 【Evaluation Methods for Wettability】 ● User Standards ● JIS-1907 Bireck Method (Measurement of water absorption by capillary action) ● Measurement of wettability over time using a contact angle meter ● For more details, please contact Wedge Co., Ltd. Electrical Division Sales Representative: Uesugi at TEL: 06-6885-6273 / FAX: 06-6885-6274 / E-mail: info.wedge-d@webcatch.jp. Mentioning "Ipros" will facilitate a smoother response.
Surface treatment is possible for films and non-woven fabrics as well. Functions such as adhesion are enhanced! Substrate treatment tests are currently underway.
At Wedge, a specialized manufacturer of surface treatment equipment, we offer a wide range of research and development and experimental test devices. We have surface treatment equipment that can accommodate various substrates, including plastic films, sheets, boards, vapor-deposited films, optical films, and high foams. The "Corona Discharge Surface Treatment Device" generates corona discharge in the atmosphere and irradiates the substrate surface to modify it. Even for substrates with low polarity, such as films, non-woven fabrics, and high foams, hydrophilicity is improved, enhancing adhesion, coating properties, wettability, and other functions. Additionally, by using the special high-frequency power supply "CTW Series," surface treatment can be performed with high precision and efficiency through corona discharge. 【Expected Improvements in Substrate Surface Functions】 ◎ Printability ◎ Hydrophilicity ◎ Adhesion ◎ Tackiness ◎ Water Absorption ◎ Adhesion ◎ Wettability ◎ Coating Properties ★ We are currently conducting substrate treatment tests using in-house test equipment. * For more details, please refer to the catalog.
