The applications of Carboxymethyl Cellulose (CMC) in paper-making industry

涂布Coating

涂布功能The functions in coating

• 高保水能力High water retention capability

• 改善流变学特性 Advance rheological characteristics

• 荧光增白剂（FWA）/光学提亮剂（OBA）的高效载体 Efficient carrying of fluorescent whitening agents (FWA) / optical brightening agents (OBA)

•   叶片润滑作用，能减少刀片上的条纹和划痕Blade lubrication, reducing streaks and scratches

• 良好的分散性 Good dispersing properties

• 干混性添加剂，允许涂布颜料具有很高的固体性Dry addition capability, allowing very high solids coating

• 高剪切率下粘度变稀，剪切变稀性 Very low high-shear viscosity, shear-thinning

• 作辅助胶粘剂，极好的粘合力 As auxiliary adhesive, excellent bonding strength

湿部Wet end

湿部涂料是一个复杂的动态体系，如今正作为一个促进效率、降低废水负荷以及提高造纸机器利润的因素日益受到关注。The wet end is a complex dynamic system that is gaining increased attention as an area for improving efficiency, reducing effluent load and improving paper machine profitability.

通过以下机制改善纸张强度： improves paper strength by the following mechanisms.

通过在纤维和其它化学成分之间形成键合，增大键合面积。NX-CMC分子停留在纤维表面，增加有效活性基团的数量。NX-CMC increases the bonded area by forming bonds between fibers and other chemicals. The NX-CMC molecules set on the fiber surface, increasing the amount of active groups available.

•分散和润滑微纤维，从而增大键合面积。NX-CMC disperses the micro fibrils increasing the specific bonding areas.

•通过分散纤维，减小纤维间的摩擦力。这降低了絮体粒径，从而能获得更佳的结构. NX-CMC disperses and lubricates fibers, which leads to reduced frictional forces between the fibers. This leads to reduced floc size and therefore a better formation can be achieved

在工艺和质量上的优势：On-Machine and Quality Benefits

• 节省精磨能耗 Savings in refining energy

• 改善了阳离子活性物的保留度 Improved retention of cationic additives

• 最大填料级别 Maximized filler levels

• 使生产商可使用较脆弱或较廉价的纤维素做原料 Incorporation of weaker or cheaper fibers

• 控制电荷平衡来得到理想的运转性 Control charge balance to achieve desired runnability

• 可调节的使用量 Retention adjustment

• 改善运转性 Improved runnability

• 较少起泡（尤其是在PAE存在时）Less foaming (especially in the presence of PAE)

表面施胶Surface sizing

• 可以与多种氧化或酶转化表面施胶淀粉一起使用，用于增强淀粉表面施胶的效果 It can be used in combination with a variety of oxidizing or enzymatic transformation surface sizing starch to enhance the effect of the surface sizing starch

• 与淀粉具有相互促进的作用，可提高表胶胶液的成膜性，控制胶液的无效渗透，减少胶液消耗量 It can improve the film-forming properties of the gelatine and control the ineffectiveness of the glue solution and reduce the consumption of glue

• 提高纸张的表面强度和耐磨性Increase the surface strength and abrasion resistance of paper.
