Application scenarios
Foam Elimination
System Cleanliness & Pitch and Stickies Removal
These chemicals are primarily used in the wet-end system of papermaking and serve as essential process aids in the paper industry. Their primary purpose is to effectively control various negative factors that may arise during the production process. For instance, they can eliminate foam in the papermaking system, maintain the cleanliness of felts and forming fabrics, and remove pitch and stickies from dryer cylinder and dry fabric surfaces. By addressing these issues, these products help improve both papermaking efficiency and product quality.
Solution
These chemicals serve as critical functional additives in the papermaking process, primarily addressing various issues in the wet-end system and production stages. Their purpose is to enhance production efficiency, optimize product quality, and reduce maintenance costs. Below is a detailed breakdown of the product categories and their core functionalities:
| Product Category | Specific Application | Application Point | Performance Description |
| Defoamers | Papermaking Defoamer | Foam control in the wet-end white water system of papermaking | Exhibits excellent foam suppression and elimination effects on fibers and white water, with no residue in the paper machine system. |
| Sizing Defoamer | Foam control in the paper machine sizing system | Delivers highly effective foam control in the sizing system and exhibits high-temperature resistance. | |
| Pulping Defoamer | Foam control in the pulping system | Adapts to significant pH fluctuations in the pulping system, effectively controlling foam under high-temperature and high-pH conditions. | |
| Cleaning Agents (Online Cleaning Agents) | Acidic Cleaning Agent | Online cleaning of paper machine felts | Highly effective against calcium carbonate deposits and acidic dissolved deposits in the paper machine system, effectively cleaning felt deposits. |
| Alkaline Cleaning Agent (e.g., 2037) | Online cleaning of paper machine felts (e.g., press felts and other fabrics) | Accelerates the removal of inorganic and organic deposits from fabrics, dissolves resins and stickies, and improves the operational efficiency of press felts. | |
| Wire Cleaning Agent (e.g., No. 2 New Viscosity Reducer) | Online cleaning of paper machine forming wires | Controls stickies, resins from chemical/mechanical pulp, and organic deposits from alkaline sizing. Suitable for continuous addition to address deposit issues on forming wires. | |
| Enzyme Preparations | Stickies Control Enzyme | Stickies control in the packaging paper industry | Rapidly cleaves ester bonds, reduces stickies adhesiveness, comprehensively controls stickies in recycled pulp, takes effect quickly, and operates effectively across a wide temperature range. |
| Stickies Control Agent | Stickies control in the packaging paper industry | Traditional stickies decomposition product, low-cost with relatively stable performance. | |
| Amylase | Native starch conversion (viscosity reduction) | Efficiently and rapidly reduces native starch viscosity, facilitating native starch conversion. | |
| Dryer Fabric Release Agent | – | Release agent for packaging paper dryer fabrics | Used for release on packaging paper dryer fabrics, supports continuous spraying, and the water-based product does not contaminate the paper sheet. |
| Pulping Bleaching Promoter | Bleaching Promoter | Enhances bleaching efficiency and reduces bleaching costs | Improves bleaching efficiency, reduces costs, and can completely replace sodium silicate. |
| Papermaking Biocides | Broad-Spectrum Biocide | Microbial control in pulp and paper mills | Highly effective and fast-acting water-based biocide, easily degradable, non-foaming, and effectively controls bacteria causing deposits and paper defects. |
| Reactive Biocide | Ultra-low-cost, highly effective biocide | Prevents the formation of inorganic/organic deposits, cleans the system, improves product quality, reduces breaks, and increases output. It is a water-based cleaning, biocidal, and anti-scaling agent. |
