Quality Control And Optimization Of Coated Kraft Paper

With the development of society and the improvement of people's living standard,demand of kraft coated paper is also increasing,because of the higher strength and the good printing performance,the kraft coated paper is substituted for the grey Manila board.Due to the advantages of the low coating weight,good strength,and excellent product appearance,it is accepted and recognized by the market of the small home appliances,beer milk beverage,etc.Its main customer base is the consumer goods industry,it is possession of better use,especially for the quality of cartons and printing requirements of higher consumer goods industry.The quality of coated kraft paper must be better and more stable in order to adapt to the current market.This article also discusses the quality control and optimization of coated kraft paper.The physical index and appearance quality of coated base paper are very important to the quality of coated paper.This article discusses the profile basis weight,moisture,bursting,folding and other index,and the quality improvement of base paper is analyzed and summarized.These are important for the quality improvement of coated kraft paper.In addition,the quality index of kraft coated paper is discussed and optimized.The better the base paper is,the more evenly the fibers are arranged,have better appearance,and the evenness is better.The strength and smoothness of the base paper are more uniform.What's the biggest thing about coated is the uniformity of profile PPS.Its influence of profile moisture and coating uniformity is larger.The coating methods of coated kraft paperboard were analyzed and optimized,such as the analysis and improvement of roughness factors,coating blade wear,Correction optimization of coating machine,Summary and optimization of operation method of coating machine,as well as improvement and optimization of the coating coulor.This article also makes a comparison between two coating and three coating,obviously,the three coating has more advantages.In addition,some experiments are analyzed in this article,the influence of chemical usage on the quality of coated kraft paper was verified,as well as the major rebult of the paper machine,the quality improvement has also been analysised.The shaking device decreases the absolute value 2?of the profile dryness.It can improve the profile.It can improve the stiffness,folding resistance and PPS of paper.PPS has greatly improved because of the third press rebult.And the amount of coating weight decreased obviously.The flotation modification has improved the paper surface sticky.The quality of the product is improved and the efficiency of the paper machine is improved.Of course,with the continuous improvement of the paper machine operation requirements,all aspects of the transformation will continue.
