This intrinsic electrostatic affinity <strong>reduces the demand for aluminum sulfate (alum) by up to 50%<\/strong><sup><\/sup>. Furthermore, it shifts the operational window from highly acidic to near-neutral sizing conditions, mitigating the negative impacts of traditional acid papermaking<sup><\/sup>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Enhanced Fiber Strength &amp; Calcium Carbonate (CaCO3) Compatibility<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Operating under near-neutral conditions enables paper mills to utilize <strong>Calcium Carbonate (CaCO3)<\/strong> as a cost-effective filler rather than being restricted to talcum powder or kaolin clay<sup><\/sup>. This significantly increases filler loading capacity, optimizes optical properties (brightness and opacity), and elevates the tensile, burst, and ring crush strength of the finished paper<sup><\/sup>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Equipment Corrosion Control &amp; Eco-Friendly Closed Water Loops<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">By drastically lowering the reliance on acidic alum and maintaining a higher system pH, LY-CRS reduces chemical corrosion on the paper machine wires, felts, and drying cylinders, extending equipment service life<sup><\/sup>. Its clean formulation ensures zero chemical build-up, making it perfect for mills operating <strong>closed-loop white water recycling systems<\/strong> to meet stringent environmental discharge standards<sup><\/sup>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Certified for Premium Food-Contact Packaging<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">LY-CRS is tailored for high-end, food-grade barrier packaging<sup><\/sup>. Its low-chloride, non-toxic properties make it the ideal sizing choice for <strong>cup paper, liquid packaging board (LPB), and premium food cardboard<\/strong>, fully matching global compliance standards for direct food-contact materials<sup><\/sup>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Application &amp; Dosage Guidelines<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">To achieve optimal sizing efficiency, please follow the technical recommendations below:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Addition Point:<\/strong> It is highly recommended to add the product continuously via a precise metering pump at a point <strong>before the fan pump (grouting pump)<\/strong> to ensure uniform distribution in the pulp stock.<\/li>\n\n\n\n<li><strong>Recommended Dosage:<\/strong> Typically <strong>2.0% to 4.0%<\/strong> based on the absolute dry fiber weight, adjustable depending on the target water-resistance metrics (e.g., Cobb value).<\/li>\n\n\n\n<li><strong>Addition Sequence (Reverse Sizing):<\/strong> For maximum sizing efficiency, adopt the reverse sizing sequence\u2014<strong>add aluminum sulfate first<\/strong>, followed by the LY-CRS emulsion.<\/li>\n\n\n\n<li><strong>System pH Control:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Keep the stock sizing pH strictly regulated between <strong>4.5 and 6.0<\/strong>.<\/li>\n\n\n\n<li>Ensure the white water under the wire is stabilized within the range of <strong>5.0 to 5.5<\/strong>.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Packaging, Storage &amp; Shelf Life<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Standard Packaging:<\/strong> Supplied in <strong>200 kg or 1,000 kg IBC plastic drums<\/strong> designed for safe international logistics and automated chemical dosing setups.<\/li>\n\n\n\n<li><strong>Storage Environment:<\/strong> Store in a cool, dry, and well-ventilated warehouse. Maintain ambient temperatures <strong>above 5\u00b0C and below 30\u00b0C<\/strong>. Avoid direct sunlight exposure, freezing conditions, and contact with concentrated alkalis.<\/li>\n\n\n\n<li><strong>Shelf Life:<\/strong> 3 months from the date of manufacture under proper sealed storage conditions.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>","protected":false},"excerpt":{"rendered":"<p>Cationic High-Dispersion Rosin Sizing Agent LY-CRS for Near-Neutral Papermaking LY-CRS is a premium-grade, low-chloride and &#8230; <a title=\"Agente de colagem cati\u00f4nico \u00e0 base de resina de pinheiro\" class=\"read-more\" href=\"https:\/\/lypaperchem.com\/pt\/cationic-rosin-sizing-agent\/\" aria-label=\"Leia mais sobre Cationic Rosin Sizing Agent\">Leia mais<\/a><\/p>","protected":false},"author":1,"featured_media":1144,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[12],"tags":[],"class_list":["post-1044","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-sizing-agents","generate-columns","tablet-grid-50","mobile-grid-100","grid-parent","grid-33"],"_links":{"self":[{"href":"https:\/\/lypaperchem.com\/pt\/wp-json\/wp\/v2\/posts\/1044","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lypaperchem.com\/pt\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lypaperchem.com\/pt\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lypaperchem.com\/pt\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/lypaperchem.com\/pt\/wp-json\/wp\/v2\/comments?post=1044"}],"version-history":[{"count":4,"href":"https:\/\/lypaperchem.com\/pt\/wp-json\/wp\/v2\/posts\/1044\/revisions"}],"predecessor-version":[{"id":1147,"href":"https:\/\/lypaperchem.com\/pt\/wp-json\/wp\/v2\/posts\/1044\/revisions\/1147"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/lypaperchem.com\/pt\/wp-json\/wp\/v2\/media\/1144"}],"wp:attachment":[{"href":"https:\/\/lypaperchem.com\/pt\/wp-json\/wp\/v2\/media?parent=1044"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lypaperchem.com\/pt\/wp-json\/wp\/v2\/categories?post=1044"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lypaperchem.com\/pt\/wp-json\/wp\/v2\/tags?post=1044"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
