APA liquid fluorescent brighteners

Ingredients: stilbene triazine derivative technical indicators: A Appearance: Amber transparent liquid B Ion: Anionic C Viscosity: ≤100mPa s D pH value:? 8-10 performance and features: 1. And combined with strong paper fibers, small PCD impact on the paper machine wet-end system. 2. There are good alkali resistance performance perborate and hydrogen peroxide. Scope: 1. fluorescent brightening in the pulp. 2. fluorescent brightening the surface sizing process. 3. The fluorescent whitening during coating. Application method: using the pulp can be added directly, but the accession process to avoid chemicals and other cations simultaneously adding and mixing in direct contact; surface sizing and coating application can be directly added to the PVA solution, CMC, and burnt liquid starch, anionic and Weak cationic synthetic sizing agent. 1.2. Use pH value, it proposed control 5.5-10.5. 3. The amount of pulp added: APA on oven dry pulp ratio of 0.1 to 1.5%, surface sizing add: not more than 0.55g / m2 (single-sided); conventional dosage coating added: absolutely dry pigment weight of 0.1 ~ 1.2%. Packaging and storage: 50kg, 240kg or 1100kg plastic drum, or provide packaging according to customer requirements.
