Abstract

Water is used to remove the product generated in plastic injection production by cooling from the mold. Chiller devices are used to keep the temperature of the heated water at the desired temperature depending on the use over time. The water heated in the injection machines is cooled with the help of the copper serpentine (exchanger) in the chiller devices and made ready for use again. In this study; the corrosion of the copper serpentine was investigated in simulated cooling water (SCW) and 1000 ppm NaNO2 added simulated cooling water environments by continuous water circulation for 21 days. The surface of the copper serpentine was examined by Scanning Electron Microscope (SEM), Energy Dispersive X-Ray Diffraction (EDS) and Atomic Force Microscope (AFM) before and after the experiments. It has been determined that the NaNO2 compound used as a corrosion inhibitor protects against corrosion by forming a protective layer on the copper serpentine.Keywords: Copper serpentine, Corrosion, NaNO2, Simulated cooling water

Özet

Plastik enjeksiyon üretiminde üretilen ürünün, kalıptan soğutularak çıkarılması için su kullanılmaktadır. Zamanla kullanıma bağlı olarak ısınan suyun sıcaklığını istenilen derecede tutmak için chiller cihazları kullanılmaktadır. Enjeksiyon makinelerinde ısınan su, chiller cihazlarında bulunan bakır serpantin (eşanjör) yardımıyla soğutularak tekrar kullanıma hazır hale getirilmektedir. Bu çalışmada; bakır serpantinin korozyonu yapay soğutma suyu (SCW) ve yapay soğutma suyuna katılan 1000 ppm NaNO2 ortamlarında 21 gün süreyle sürekli su devir daimi yapılarak araştırılmıştır. Deney öncesi ve sonrası bakır serpantinin yüzeyi Taramalı Elektron Mikroskobu (SEM), Enerji Dağılımlı X-Ray Kırınımı (EDS) ve Atomik Kuvvet Mikroskobu (AFM) yöntemleri ile incelenmiştir. Korozyon inhibitörü olarak kullanılan NaNO2 bileşiğinin, bakır serpantin üzerinde bir koruyucu film oluşturarak korozyona karşı koruduğu belirlenmiştir.Anahtar Kelimeler: Bakır serpantin, Korozyon, NaNO2, Yapay soğutma suyu
