The Research And Practice Of Slight Coating Technology Of Munken Paper

This topic comes from the independent project of our company.At present,our munken paper’s certain indicators can not meet the needs of high-grade printing,mainly for it’s low smoothness,high ink absorption and bleak printing color.This topic through trace coating on munken paper by gate roll coating machine,to solve the above problems of munken paper,developed a Takamatsu thickness and surface of delicate environmental protection high-grade printing paper slight coating paper for light.Difference to traditional light weight coated paper,light slight coating paper on paper gloss does not require,but for the paper has a high bulk,from the point of view of performance index,characteristics of trace coating munken paper both munken paper and light weight coated paper,paper loose thickness greater than 1.30cm3/g,far superior to ordinary light weight coated paper and double gummed paper,and paper surface smooth degree compared munken paper has been greatly improved,applicable to high-end color printing.By using a higher proportion of chemical mechanical pulp,the paper gives a higher.At the same time,in order to improve the paper surface smoothness by soft calender of coating base paper were precalendering finishing,and the three component to help retention and drainage system improves the network Department of the base paper retention performance,improve the base paper surface smoothness.At the same time,for the munken paper sheet of porous structure,resulting in coating adhesive to the interior of the base paper excessive migration,developed for munken paper special coating formulations,improve the coating base paper coverage performance and strength.The successful development of the slight coating paper has realized the upgrading of the company’s products.Because of its high yield pulp ratio in more than 70%,so it has the characteristics of low carbon environmental protection.At the same time,because of its high bulk,printing can using the same thickness of the low gram weight coated munken paper to replace the high gram weight of ordinary double gummed paper,so as to be convenient to the readers,saving resources.Slight coating munken paper paper surface smooth and delicate,full of bright colors,clear and strong sense of three-dimensional image,suitable for high-grade color printing,so that it has the characteristics of environmental protection paper and high-grade printing paper.
