Oil-Based Defoamers: A Necessity Across Various Industries
Oil-based defoamers, distinguishable by their quick foam-dissipating features and broad versatility, are a preferred anti-foaming solution in several industries. Their formulation, typically featuring an oil carrier accompanied by hydrophobic particulates, caters effectively to various foaming systems. This chapter delves into industries where these defoamers are prominently deployed.
Pulp and Paper Industry
In the pulp and paper-making sector, foaming can lead to severe complications like process bottlenecks, pump cavitation, and sheet defects, disrupting smooth operation and product quality. Oil-based defoamers swiftly counteract foam in pulp washing and paper-making processes, promoting uninterrupted production flow. The highly resistant film of these defoamers effectively destabilizes the foam, leading to its rapid collapse.
Coatings Industry
The manufacture and application of coatings, such as paints and inks, are processes often impeded by unwanted foam generation. This foam can compromise the coating’s appearance, leading to a poor finish, pinholes, or reduced gloss. The fast-acting foam knockdown properties of oil-based defoamers are instrumental here, ensuring the final product’s aesthetic and functional quality. They help achieve a smoother, impeccable finish by eliminating the foam that might cause surface defects.
Petroleum Industry
In the petroleum industry, oil-based defoamers are extensively used during crude oil refining. The separation of crude oil into various components involves heat and agitation, which can often cause foam formation. This foam can overflow from tanks and slow down the separation process. Oil-based defoamers help prevent such hindrances, enabling efficient separation and minimizing process downtime.
