01
Pulp
Pulping separates lignin and cellulose. Kraft pulping (common method) dissolves lignin with chemicals, leaving cellulose for paper. This process creates surfactants that reduce washing efficiency. Jing Wei defoamers improve washing, reduce solids, lower water use, and enhance drainage. Suitable for hardwood/softwood pulp in various concentrations.
02
Paper Machine
Paper machines turn pulp into paper sheets. Additives enhance wet/dry strength, texture, color, and surface. Friction and chemicals create foam in the headbox, wire pit, and recycle systems. Defoamers are crucial to maintain production standards. Jing Wei offers options for temperature, concentration, cost, and paper type.
03
Coating
Special papers get a coating for color, adhesion, or properties like gloss/ink resistance. Applied and dried at the end, the coating needs defoamers to prevent bubbles harming surface quality. Jing Wei offers customized defoamers for all coating types, ensuring a perfect finish while meeting your performance and cost considerations.
04
Water Treatment
Closed-loop paper mills with water treatment plants face foaming issues due to residual surfactants. This can disrupt pumps, cause overflows, and impact paper machines. Jing Wei offers eco-friendly, water-dispersible defoamers for easy dosing, controlling foam throughout the water treatment process, and ensuring efficient production.
