"YC/T26-2008 tobacco cellulose diacetate tow" tobacco industry standard

1、The dissolution process adopts continuous dissolution process, and the DCS system is used to finely control the adding flow of various raw materials, which can avoid the undissolved vinegar flake particles from blocking the slurry transfer pump on the basis of reducing the labor load of operators and effectively improve the control level and product quality.

2、The titanium dioxide slurry preparation process adopts wet crusher instead of plate and frame filter press, which reduces the loss of titanium dioxide and improves the quality of slurry.

3、The filtration process adopts quantitative filtration technology instead of constant pressure filtration technology, and adopts single flow management to stabilize filtration flow rate, reduce filament breakage, achieve fine filtration and improve spinnability.

4, dilute acetone delivery method from intermittent batch delivery to continuous quantitative delivery, to avoid the fluctuation of dilute acetone concentration, and then stabilize the production conditions of the distillation process.

5、The spinning process adopts two different series of spinning machines, each series can operate independently, which can effectively meet the production needs of multi-specification products and has greater production flexibility.

6、DF oil emulsion process is changed from online mixing to trans-phase emulsification, so that the emulsion is evenly attached to the yarn bundle, reducing the amount of rolled stick flying hair.

7, acetone recovery process increased the air collection box and hygrometer, effectively reducing acetone loss.
