Sodium Metasilicate for the Paper Industry
Paper and pulp operations use sodium metasilicate as an alkaline processing aid in deinking, pulping auxiliaries, and equipment cleaning formulations within the mill chemical program.
Updated
Short answer
Paper and pulp mills use sodium metasilicate as an alkaline processing aid in deinking, pulping auxiliaries and equipment cleaning within the mill chemical program, where it stabilises peroxide bleaching and helps keep detached ink dispersed. There is no single default grade: selection follows the process stage and the make-up method, so send the stage and your specification for review rather than ordering against the application name. Zhongzhi Chemical supplies granular and pentahydrate grades from China with COA, SDS and REACH documentation.
How Sodium Metasilicate Is Used
- Deinking and pulping auxiliary chemicals
- Alkaline cleaning of paper machine equipment
- pH control in selected process stages
- Component in multi-chemical mill treatment packages
Benefits for This Industry
- Specification review for recurring paper and pulp chemical orders
- Packing and loading details confirmed according to order requirement
- Export packaging suitable for long-distance shipment
- Combined orders with detergent-grade metasilicate for distributors
How Our Sodium Metasilicate Supports This Application
| Formulation need | Product feature | Value to your line |
|---|---|---|
| Stabilise peroxide bleaching | Alkaline silicate buffering | Steadies pH so peroxide bleaching stays controlled |
| Keep detached ink dispersed in deinking | Silicate dispersing and deflocculation action | Helps prevent ink redeposition during deinking |
| Alkaline cleaning of machine equipment | Strong alkalinity | Effective cleaning of paper-machine equipment |
| Grade matched to the process stage | Granular and pentahydrate grades | Grade follows the stage and make-up method, not the application name |
| Recurring long-distance mill supply | Export packing with batch COA | Reliable shipment and documentation for repeat orders |
Grade selection depends on your mill process. Submit your specification requirements for quotation review.
