PENANGANAN KERAK PADA HANDLING EQUIPMENT MACHINE

Rizki Novianto

Abstract


Pengerakan Ferro karbonat tidak hanya fenomena kristalisasi yang terbentuk dalam proses alami (biomineralization), tetapi merupakan masalah yang sering ditemui dalam berbagai alat berat seperti bulldozer (Alice et al., 2011). Hal ini disebabkan karena terdapatnya unsur-unsur pembentuk kerak seperti besi dan karbonat dalam jumlah yang melebihi kelarutannya pada peralatan berat. Kerak biasanya mengendap dan tumbuh pada peralatan industri seperti pada pipa pipa hidrolik alat berat. Kerak merupakan suatu deposit dari senyawa-senyawa anorganik yang terendapkan dan membentuk timbunan kristal pada permukaan suatu subtansi. Kerak merupakan suatu deposit dari senyawa-senyawa anorganik yang terendapkan dan membentuk timbunan kristal pada permukaan suatu subtansi.  Hal ini disebabkan karena terdapatnya unsur-unsur pembentuk kerak seperti alkalin, magnesium, kalsium, klorid, sulfat dalam jumlah yang melebihi kelarutannya pada keadaan kesetimbangan. Kerak biasanya mengendap dan tumbuh pada peralatan industri seperti cooling tower, heat exchangers, pipe, casing manifold, tank dan peralatan industri lainnya
