AI Summary
Nano ZEO® Eco-friendly Powder can be introduced into a corrugated-board starch-adhesive system as a functional mineral additive. A reliable trial should treat it as a controlled formulation change: confirm powder dispersion, addition sequence, adhesive viscosity and temperature, glue pickup, bonding, drying and finished-board performance. There is no single universal dosage or machine setting; the working window must be established on each plant, adhesive recipe, paper combination and corrugator.

Why Introduce Nano ZEO® Through Starch Glue?
Starch glue is applied continuously at the flute tips and becomes part of the paperboard bond after heating and drying. Introducing a well-dispersed functional powder through this existing wet process can distribute Nano ZEO® across the bonded corrugated structure without adding a separate coating step.
The objective is not simply to pour powder into a glue tank. The objective is to obtain a stable, pumpable and coatable adhesive that runs on the corrugator and produces consistent bonds. The finished board—not the glue alone—is the final verification object.
1. Establish a Baseline Before the Trial
Record the normal starch-glue recipe, batch size, water quality, starch and auxiliary materials, mixing sequence, mixing time, temperature profile, viscosity method and reading, solids content where available, gelatinization behavior, storage time and machine speed. Also record paper grades, basis weights, flute type and environmental conditions.
Produce a control batch without Nano ZEO® under the same conditions. This baseline makes it possible to identify whether any change comes from the additive or from normal production variation.
2. Prepare for Uniform Dispersion
Nano ZEO® should be introduced in a way that avoids floating powder, agglomerates and localized high concentration. The practical sequence depends on the plant’s adhesive system. In general, select a stage with sufficient liquid and effective agitation, add the powder gradually, and allow adequate mixing before final process adjustment.
Do not assume that the mixing sequence used on one line can be copied unchanged to another. Powder feeding, mixer geometry, shear, batch volume and starch formulation all affect dispersion. Check the batch visually and, where practical, inspect a representative sample for sediment, agglomeration and short-term stability.
3. Recheck Adhesive Process Properties
After addition, confirm the properties that control transfer and bonding. These normally include viscosity measured by the plant’s defined method, adhesive temperature, flow and pumpability, storage stability, glue-film uniformity and pickup at the applicator roll.
If adjustment is required, change one variable at a time and document it. A correction made only to reach the previous viscosity number may not restore the same application behavior, so both the adhesive reading and the machine result should be observed.
4. Control Glue Application on the Corrugator
During the first machine trial, use a defined and traceable run rather than mixing several paper combinations at once. Observe glue-pan circulation, foaming, deposits, metering-roll behavior, glue-line continuity and pickup at the flute tips. Monitor board warp, blistering, washboarding, delamination and edge bonding.
Machine speed should be increased only after the glue transfers consistently and the bond remains stable. Any operating window stated for commercial production should be based on the plant’s recorded trial rather than a universal claim.
5. Confirm Heating and Drying
Starch bonding develops through heat transfer, gelatinization and moisture removal. A formulation change may influence water demand, heat transfer and the time needed to reach a stable bond. Monitor hot-plate or dryer conditions, board temperature where available, line speed, residual moisture and post-production conditioning.
Avoid using “dry” appearance as the only acceptance criterion. Board should be conditioned according to the selected test method before comparing physical properties.
6. Validate the Finished Corrugated Board
A staged validation is recommended: laboratory drawdown or small batch, limited machine trial, controlled production lot, and repeat lot. Depending on the intended application, assessment may include adhesive bond quality, pin adhesion or another internal bond method, edge crush strength, burst strength, box compression strength, moisture content, warp, print or converting performance, and storage or transport evaluation.
Test method, specimen preparation, conditioning, sample size and acceptance criteria should be agreed before the trial. Results from one paper combination or flute profile should not automatically be transferred to another.
7. What Should Be Recorded?
Keep a trial sheet covering material lot, addition point, addition rate, batch sequence, mixing time, temperature, viscosity method and result, solids content if measured, glue pickup, machine speed, dryer settings, paper combination, ambient conditions, observed defects and finished-board test results. Retain control and trial samples when possible.
This record turns a one-time experiment into a repeatable production method and provides the evidence needed for customer communication.
Responsible Technical Communication
Nano ZEO® is a functional additive, not a substitute for process validation. Exact formulation ratios, proprietary preparation details and customer-specific settings should be managed as controlled technical information. Claims such as a fixed strength increase, guaranteed water resistance or a specific reduction in paper basis weight should only be published when supported by a current report that identifies the formulation, test conditions and applicable standard.
纳米ZEO®如何导入淀粉胶？从制胶、上糊到烘干的工艺控制
AI摘要
纳米ZEO®环保粉料可作为功能性矿物添加材料，导入瓦楞纸板使用的淀粉胶体系。可靠的导入方式，应把它视为一次受控的配方变更，依序确认粉料分散、添加顺序、黏度与温度、上糊量、黏合、烘干及成品纸板性能。不存在适用于所有工厂的单一添加比例或机台参数；实际工作窗口必须根据各工厂、胶水配方、纸张组合及瓦楞机验证。

为什么通过淀粉胶导入纳米ZEO®？
淀粉胶会连续涂布在楞峰，并在加热、干燥后成为纸板黏合结构的一部分。通过既有湿式制胶流程导入分散均匀的功能粉料，可让纳米ZEO®分布于瓦楞纸板的黏合结构中，不必另外增加独立涂层工序。
导入目标并不是把粉料直接倒进胶桶，而是取得稳定、可输送、可涂布，并能在瓦楞机上持续生产的胶液。最终需要验证的是纸板成品，而不只是胶液本身。
一、试产前先建立基准
记录日常淀粉胶配方、批次容量、水质、淀粉与辅助材料、混合顺序、混合时间、温度变化、黏度测试方法及读值；具备条件时，也记录固含量、糊化状态、储存时间与机速。同时记录纸种、克重、楞型及环境条件。
在相同条件下制作未添加纳米ZEO®的对照批次，才能判断观察到的变化来自添加材料，还是一般生产波动。
二、建立均匀分散
纳米ZEO®应以能够避免粉料漂浮、结团及局部浓度过高的方式导入。实际添加阶段取决于工厂使用的制胶系统。一般原则是选择液相充分且搅拌有效的阶段，逐步加入粉料，并在最后调整工艺前给予足够混合时间。
不同生产线的投料方式、搅拌器结构、剪切程度、批次容量及淀粉配方都会影响分散，因此不能把某一条生产线的混合顺序直接套用于另一条线。应目视检查胶液，并在可行时抽取代表性样品，观察沉降、结团及短时间稳定性。
三、重新确认胶液工艺性质
添加后，应确认影响输送、上糊及黏合的性质，通常包括依工厂既定方法测得的黏度、胶液温度、流动与泵送状态、储存稳定性、胶膜均匀性，以及上糊辊的带胶状态。
需要调整时，一次只改变一个变量并留下记录。单纯把黏度数字调回原值，不一定能恢复相同的涂布行为，因此胶液读值与机台表现都必须观察。
四、控制瓦楞机上糊过程
首次上机应采用明确且可追溯的试产批次，不要同时混用多种纸张组合。观察胶盘循环、起泡、沉积、计量辊状态、胶线连续性与楞峰上糊，并监测翘曲、起泡、搓衣板、开胶及边缘黏合状况。
确认胶液转移稳定、黏合保持正常后，再逐步提高机速。任何对外使用的量产工艺窗口，都应来自该工厂有记录的试产结果，而不是通用数字。
五、确认加热与烘干
淀粉黏合需要经过热传递、糊化与水分移除。配方改变可能影响需水量、热传递及形成稳定黏合所需的时间。应监测热板或干燥段条件、可取得时的纸板温度、机速、残余水分与生产后的调湿状态。
不要只以表面看似干燥作为合格标准。比较物性前，应依选定测试方法对纸板进行调湿处理。
六、验证瓦楞纸板成品
建议采用分阶段验证：实验室涂布或小批次、限定范围的上机试产、受控量产批次，以及重复批次。依实际用途，评估项目可包括黏合品质、针式黏合强度或其他内部黏合方法、边压强度、耐破强度、纸箱抗压强度、含水率、翘曲、印刷与后加工表现，以及储存或运输验证。
试产前应先约定测试方法、试样制备、调湿条件、样本数量与验收标准。一个纸张组合或楞型的结果，不能直接套用到其他组合。
七、试产记录应包含什么？
建议建立试产记录表，包含材料批号、添加位置、添加速率、批次顺序、混合时间、温度、黏度方法与结果、可取得时的固含量、上糊状态、机速、干燥设定、纸张组合、环境条件、异常现象及成品测试结果。条件允许时，应保留对照样与试产样。
完整记录能把一次性实验转化为可重复的生产方法，也能为后续客户沟通提供依据。
负责任的技术说明
纳米ZEO®是一种功能添加材料，不能取代工艺验证。确切配方比例、专有制备细节及客户专属设定，应作为受控技术信息管理。固定强度提升幅度、保证耐水时间或特定纸张克重降低等说法，只有在现行报告明确列出配方、测试条件及适用标准时才应对外发布。
