Study On Influence Factors Of The Smoothness Of Tipping Base Paper

Smoothness of paper means time of certain airs of volume passed the nip between certain pattern surface and the glass under certain pressure and certain vacuity, express by 's'. The longer time is, the better the smooth performance of paper surface is, and the higher smoothness is.Smoothness of paper used for printing has heavy influence to printing quality. To obtain satisfactory printing quality, smoothness degree of the paper is an essential condition. The printing smoothness is the most important condition to get the printed matter of the original manuscript faithfully on the paper. It determine the touch degree between paper surface and printing plate, which apply ink to paper, or rubber cloth when printing impress in the twinkling of an eye, it is important influence factor if the transformation of the printing ink is overall or the picture and text is the clear or not. According to the fact of the production, this article studied on the fiber material, the filing, the ash content, the moisture content as well as soft calendar several factors affected the smoothness of the tipping base paper, and obtained some research conclusions and the result.Tipping base paper is also called the connecting and holding base paper for cigarette. The Tipping base paper, as a kind of related printing paper of cigarette industry, the smoothness influence factors are essentially identical with the other printing paper. Raw materials for producing tipping base paper, quality index, the production process and operation method, and equipment performance of paper machine are four respects of the influence factors.Because the fiber in length, width, and thickness is different, smoothness degree of paper produced by a large amount of long fiber is lower than that of paper produced by a large amount of short fiber. In another words, short-fiber and broke can improve the smoothness degree of paper. The function of the fine fiber can't be ignored in most paper grade production.Because fine fiber component can pack long fiber space of grid structure well, thesurface of the paper page is smoother; the smoothness degree improves notably.As the long fiber refined, the fiber length, width, and thickness, etc. are reduced tosome extent, the fine fiber contents increase. The broke contain a large number of finefibers. Increasing the shopper degree of the fiber and joining the suitable broke pulpin the production of tipping base paper, contribute to improving the paper formationand smoothness degree.The filling is the indispensable auxiliary material in papermaking. Influence of fillingin smoothness degree, opacity, and compressing of paper is very great to printingpaper. The size of the filling particle influences the paper surface roughness degree, thelittler filling particle is, the more obvious fill function is, on an equal basis of press,calendar technological terms, the better to improving the smoothness function is.Improvement of ash content in paper can improve smoothness degree of the paper to acertain extent.Keeping the other working conditions of the papermaking same basically, smoothnessof the paper increase more obvious with the moisture content increased.Soft calendar deal with the paper is very obvious to influence the smoothness degree.Increasing the line pressure can obviously improve smoothness degree of the paper; itis one of the main means of improving the smoothness degree. The hard roll surfacetemperature is one of the influence factors of smoothness degree too, increasing thesurface temperature can improve the paper smoothness too, and the range just is notso obvious as the line pressure.Compare influencing factor as fiber materials, filling, moisture content, ash content,line pressure and surface temperature of soft calendar level and smooth degree, papermoisture and the line pressure are the main factors of influencing the smoothness.Keeping the other working conditions of the papermaking same basically, the betterpaper formation is, the higher smoothness is, and the more even smoothness is.
