影响瓦楞纸板返潮率因素的研究

Study on Factors of Influencing Getting-damp of orrugated Paper Board

瓦楞纸板返潮的原因主要来自制作瓦楞纸板的载体淀粉胶粘剂。用H、P、Q、W等物质分别对载体淀粉胶粘剂进行改性的研究 ,通过筛选试验和综合分析 ,确定了复合添加剂用量的最佳配方 ,结果表明控制复合添加剂用量 (以淀粉重量 %计 ) 1 1 %～ 1 2 % ,氢氧化钠用量 3.2 % ,制成的改性淀粉载体胶粘剂粘度适宜 ,用这种胶裱制的瓦楞纸板返潮率低 ,粘结强度高。

The getting-damp of corrugated paper board results from borne starch adhesive used to manufacture corrugated paper board .It is investiaged that borne starch adhesive is modified by usingmaterial H,P,Q,W and so on .Optimal dosage is selected by test and comprehensive analysis.Resultshow that viscosity of modified borne starch adhesive is approppriate when dosage of complex additiveis 11% ～ 12%(percent of starch weight),NaOH 3.2% .Rate of getting-damg of corugated paper boardmanufactured by using the modified borne starch adhesive ,The strength is high.
