改善酶转化玉米原淀粉的表面施胶胶料使用性能

摘要

淀粉酶连续转化玉米原淀粉能大幅降低表面施胶胶料成本达到降低纸产品成本的目的，但同时需要改善表面施胶胶料的使用性能，否则可能影响施胶效果和产品质量。太阳纸业天章#19机使用淀粉酶连续转化木薯原淀粉和玉米原淀粉代替阳离子氧化生淀粉，通过提高原淀粉的质量、提高活化温度和储存温度等措施成功地改善了表面施胶胶料的使用性能，保证了施胶效果和产品质量。%Transforming corn starch continuously with starch enzyme can reduce the cost of paper products by dramatically reducing surface sizing cost, at the same time the surface siz-ing liquid performance need to be improved, otherwise it may affect the sizing effect and paper quality. Raw cassava and corn starch continuously transformed with starch enzyme were ap-plied in Tianzhang PM19, Sun Paper, in place of cationic oxi-dized starch. The performance of the surface sizing liquid was improved by raising raw starch quality and raising the activation temperature and storage temperature, to ensure the sizing effect and paper quality.
