Study On Composite Packaging Film Of Beet Fiber

The thesis studied beet fibre changes carboxyl of the nature methyl cellulose (CMC)/ poval (PVA)/ amylum to different to ratio preparation compound package film , the factor tests that by becoming film Shan, every factor orthogonality tests film to the tensile strength , tearing elongation rate being different condition preparation compound film , hinder oxygen , film function aspect such as hinder wet , penetrating the oiliness , transmitting rate , film thickness from having carried out examination, third the best film of compound condition. Test the detecting having carried out seven on compound film originally, in order to get the synthetical fairly good function compound film, have worked out that compound film function synthesizing the principle grading , has adopt piecewise interpolation to be in progress to various compound film function grading synthetically , has applied paralleling testing that conditional being in progress verifies to the best , has checked that through and, discover be test result of equal rank's turn and orthogonal test result coinciding. Concrete content as follows:The experiment draws by a beet being done after acid splitting after dregs of rice steeps half hour in advance , use alkaline hydrolysis to carry out degeneration again, the queen treatment and etherification bleaching are processed manufactures CMC. Compound the carboxyl methyl cellulose solution and 5% poval solution again respectively, the certain thickness amylum solution carries out commixture , adds 2% glycerin, add the appropriate amount Glutaraldehyde The pH adding ammonia , adjusting ready-made film liquid arrives at weak basicity , 0.5 hour of queen will become film liquid upside down on becoming film board , 6 h, expose 85℃lower drying film.Become film condition secondly by the fact that the cellulose and poval becoming film liquid thickness and matching for ratio, Glutaraldehyde thickness and eight aspect such as dosages , pH, elasticizer , ammonia water dosages , the drying temperature , ready-made film medium to carboxyl methyl, different to here condition goes down the preparation compound film tensile strength , tearing elongation rate , hinders oxygen, film function aspect such as leaking outing wet , penetrating the oiliness , transmitting rate , film thickness from having carried out examination. The handicraft has carried out investigation and discussion on the best.The synthesis making use of piecewise interpolation to be in progress to various compound film function finally grades , apply and paralleling testing that conditional being in progress verifies to the best, data result testing that in compound film orthogonality indicates is optimum condition for ready-made a film , analyse by the fact that the orthogonality to preparation compound film tests form result's, may know the compound film film function , analyse by the pole difference to the compound film tensile strength and tearing elongation rate, being qualified for discovering film is most notable than the tensile strength and elongation rate to compound film affect effect , other is dialdehyde dosages , ammonia water dosages , become film liquid thickness affecting a minimum.
