Background technology
The tiny component of paper pulp is the important component part of raw material of papermaking fiber.Tiny component not only can have influence on the operational process of paper machine, such as keeps, drainage, Save All System, auxiliary agent effect, rate of drying etc., also can have influence on the multiple performance of paper, as paper structure, physical strength, optical property, printing performance etc.
Paper-making process is generally to distinguish long fibre fraction and tiny component with the screening component of paper pulp.Be the circular hole of 75 μm or the particle of fibre classifier 200 mesh sieve by diameter in paper making raw material, be counted as tiny component.The component of mixture of the staple fibre of grass class chemical pulp below 100 orders, heteroproteose cell etc. is fiber fines; Usually mechanical pulp and chemi-mechanical pulp are called fiber fines by components such as 200 object fibre debris, thread fiber fines, fibrous bundles, also have and will be called fiber fines by 100 object fibre fractionations; The staple fibre of chemical wood pulp below 200 orders and fibrous bundle component are fiber fines.
The tiny component of tobacco pulp and the tiny component of common paper pulp different.Its fiber quality of the paper pulp that paper-making process uses is higher, and tiny component mainly refers to a large amount of stringiness fiber fines and a small amount of non-fiber heteroproteose cell.Papermaking-method reconstituted tobaccos produce in the tobacco pulp that uses comprise offal slurry, offal slurry and fragment slurry, wherein in offal slurry containing a large amount of stringiness fiber fines, and offal slurry and fragment starch in non-fiber heteroproteose cell be main tiny component.
The tiny component concentration of current measurement paper pulp adopts sieve method usually.Utilize Bauer-McNett fibre analyser (Bauer formula Pulp Fiber Fractionation instrument) can be separated and collect the fiber fines of different size, measure the percentage by weight of fiber at different levels, but this method wastes time and energy, water consumption is large, often have fiber loss in various degree in screening process, causes test result difference between Duplicate Samples larger.Utilize the KajaaniFS-300 fibre analyser of Finland while analyzing the fibre length of paper pulp, width, rugosity, curling, kink, fibrous bundle content, also can obtain the content of fiber fines, but it requires higher to the fiber quality of the kind of paper pulp and paper pulp, for containing thick fibrous bundle, offal, tobacco leaf fragment tobacco pulp fibrous suspension flow through kapillary time easily block, FS-300 is not suitable for mechanical pulp, is not suitable for the content analyzing tiny component in tobacco pulp.The FQA fiber quality analyzer that OpTest Equipment company of Canada produces then is applicable to the more paper pulp of fibre-bearing bundle (as mechanical pulp, old newspaper slurry, tobacco pulp etc.), but it is the same with Kajaani fibre analyser all belongs to costly instrument, be only applicable to laboratory study, its test result can not meet the product control requirement of factory and enterprise to pulp quality, can not be used to guide production.
