Significant Boost to Wet Strength Ratios<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Standard, untreated paper sheets typically lose almost all structural cohesion when saturated with water, retaining a mere 2% to 10% of their original dry tensile strength<sup><\/sup>. The addition of LY-WA401 remedies this by establishing a cross-linked thermosetting network among cellulose fibers, successfully elevating the wet strength of the finished sheet to <strong>\u043e\u0442 20% \u0434\u043e 40% \u043e\u0442 \u0441\u0432\u043e\u0435\u0439 \u043f\u0435\u0440\u0432\u043e\u043d\u0430\u0447\u0430\u043b\u044c\u043d\u043e\u0439 \u043f\u0440\u043e\u0447\u043d\u043e\u0441\u0442\u0438 \u0432 \u0441\u0443\u0445\u043e\u043c \u0441\u043e\u0441\u0442\u043e\u044f\u043d\u0438\u0438<\/strong><sup><\/sup>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. High Fiber Performance Preservation Without Yellowing<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike obsolete aldehyde-based resins, LY-WA401 improves wet tensile strength without degrading the original softness, texture, or liquid absorbability of the paper matrix<sup><\/sup>. Furthermore, it uses low dosage amounts, resists thermal degradation (heat resistance), and minimizes the &#8220;yellowing phenomenon&#8221; common in high-brightness white papers<sup><\/sup>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Highly Cost-Effective Broke Repulping &amp; Recovery<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A major disadvantage of traditional wet-strength resins is the extreme difficulty in recycling damaged or scrap paper rolls. LY-WA401 overcomes this operational hurdle<sup><\/sup>. While it provides robust water resistance during end-use, the broke or waste paper remains <strong>highly responsive to industrial repulping processes<\/strong>, cutting down energy consumption in the hydration loop and preventing fiber waste<sup><\/sup>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Broad Sizing Synergy &amp; Multi-Action Wet-End Benefits<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">LY-WA401 operates efficiently across acidic, neutral, and medium-alkaline papermaking conditions<sup><\/sup>. It features a strong cationic charge that works well alongside rosin sizing agents and aluminum sulfate (alum)<sup><\/sup>. Beyond wet reinforcement, it acts as a secondary process aid, providing excellent retention and drainage-filtration benefits to improve overall paper machine line speed<sup><\/sup>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">\u0420\u0435\u043a\u043e\u043c\u0435\u043d\u0434\u0430\u0446\u0438\u0438 \u043f\u043e \u043f\u0440\u0438\u043c\u0435\u043d\u0435\u043d\u0438\u044e \u0438 \u0434\u043e\u0437\u0438\u0440\u043e\u0432\u043a\u0435<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">To capture maximum retention and ensure absolute blending without polymer shearing, follow these procedures:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>\u0420\u0430\u0437\u0431\u0430\u0432\u043b\u0435\u043d\u0438\u0435:<\/strong> The concentrate should be pre-diluted with <strong>cold water down to a 5% solution<\/strong> prior to system injection.<\/li>\n\n\n\n<li><strong>\u0422\u043e\u0447\u043a\u0430 \u0441\u043b\u043e\u0436\u0435\u043d\u0438\u044f:<\/strong> To guarantee complete, homogeneous distribution through the pulp stock while avoiding excessive mechanical shear forces, the chemical addition point must be located <strong>\u0440\u044f\u0434\u043e\u043c \u0441 \u043d\u0430\u043b\u0438\u0432\u043d\u044b\u043c \u044f\u0449\u0438\u043a\u043e\u043c<\/strong>.<\/li>\n\n\n\n<li><strong>\u0425\u0438\u043c\u0438\u0447\u0435\u0441\u043a\u0430\u044f \u0441\u043e\u0432\u043c\u0435\u0441\u0442\u0438\u043c\u043e\u0441\u0442\u044c:<\/strong> Because it is a highly active cationic resin, it <strong>must not be directly mixed or pre-blended with anionic substances<\/strong> or untreated anionic additives to prevent precipitation or gelling.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">\u041e\u0441\u043d\u043e\u0432\u043d\u044b\u0435 \u043e\u0431\u043b\u0430\u0441\u0442\u0438 \u043f\u0440\u0438\u043c\u0435\u043d\u0435\u043d\u0438\u044f \u043f\u0440\u043e\u0434\u0443\u043a\u0446\u0438\u0438<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">LY-WA401 features an extraordinarily wide application scope across modern paper manufacturing sectors, proving highly effective for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Sanitary &amp; Toweling Papers:<\/strong> Household tissue paper, pocket tissues, and paper towels requiring instant liquid absorption combined with high wet durability.<\/li>\n\n\n\n<li><strong>Specialty &amp; Agricultural Barriers:<\/strong> Fruit-growing protection bags, agricultural wraps, and heavy-duty liquid packaging board (LPB).<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">\u0423\u043f\u0430\u043a\u043e\u0432\u043a\u0430, \u0445\u0440\u0430\u043d\u0435\u043d\u0438\u0435 \u0438 \u043e\u0431\u0440\u0430\u0449\u0435\u043d\u0438\u0435<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Packaging Logistics:<\/strong> Shipped in heavy-duty <strong>\u041f\u043b\u0430\u0441\u0442\u0438\u043a\u043e\u0432\u044b\u0435 \u0431\u043e\u0447\u043a\u0438 \u043e\u0431\u044a\u0435\u043c\u043e\u043c 200 \u043a\u0433 \u0438\u043b\u0438 \u043a\u043e\u043d\u0442\u0435\u0439\u043d\u0435\u0440\u044b IBC \u0432\u043c\u0435\u0441\u0442\u0438\u043c\u043e\u0441\u0442\u044c\u044e 1 000 \u043a\u0433<\/strong> to seamlessly match automated chemical feeding and metering infrastructures.<\/li>\n\n\n\n<li><strong>\u0423\u0441\u043b\u043e\u0432\u0438\u044f \u0445\u0440\u0430\u043d\u0435\u043d\u0438\u044f:<\/strong> Maintain pristine conditions inside a cool, dry, and properly ventilated facility at temperatures <strong>\u043e\u0442 5 \u00b0C \u0434\u043e 30 \u00b0C<\/strong>.
