THE CHARACTERISTIC OF GEOMETRICAL PARAMETERS OF CELLULOSE FIBERS IN PULP USING PROBABILISTIC APPROACH
Abstract
Advantages of the mathematical description of geometrical fibers parameters of the polydisperse cellulose half-finished product measured on the automatic analyzer FiberTester using probabilistic-statistical methods are shown. With application specially developed and registered in Federal Institute Industrial Property software the possibilities of additional processing of experimental data are shown. Parameters of lognormal distribution for length and width of fibers with parameters m and sx, and exponential distribution for curvature of fibers with parameter l for hardwood and softwood kraft pulp, both bleached and not bleached are calculated.
It is established, that changes of average values of fiber length and width and the form-factor, corresponds to change of parameters of distribution m and l for different grades of kraft pulp
It is experimentally confirmed, that the interrelation between separate characteristics of cellulose fibers has probabilistic character as strict functional dependences take place only for average values in classes of length, and in a separate class on length such dependences are absent completely.
It is offered to use distribution parameters of fibers characteristics for a quantitative estimation papermaking potential of fibrous half-finished products and modeling of paper structure with the adequate fiber probabilistic-statistical characteristic.
