Abstract
A plate-type compound filter cloth for filtering cellulose acetate size is a three-layer structure, which is composed of the top and bottom layers of degreased and bleached pure cotton cloth in different specifications and filter core which is chosen from three different quality cotton fiber and wood fiber, so having three types. Said three layers are combined together by coating adhesive insoluble in acetone, hot compounding and baking. Its advantages are high filter speed and effect, and high strength.
Description
The present invention aims at cellulose acetate dope filtration filter cloth.
Cellulose acetate dope filtration filter cloth of the prior art, the general cotton of two-layer same specification up and down that adopts, middle filter core is pure cotton non-woven fabrics, short linter pulp cypress etc., and its filtering rate and filter effect are not ideal, and anti-bursting brute force still can.The filter cloth of making filter core with short linter pulp cypress has a spot of short velveteen to enter in the slurries when the cellulose acetate slurries filter by filter cloth, directly influences the filter quality of slurries.
The object of the present invention is to provide a kind of anti-bursting powerful height, have filtering rate preferably, have good filter effect again, be exclusively used in plate-type compound filter cloth for filtering actylcellulose size slurry.
Technical solution of the present invention is:
Cellulose acetate dope filtration plate-type filter cloth, the difference of itself and prior art is: can be according to quality control requirement after the filtration of cellulose acetate slurries and filtering technique condition, the board-like compound filter cloth that can adopt three kinds of unlike material filter cores to make respectively mates, and can reach the quality requirement of acetate fiber spinning level or cinefilm (X sensitive film) film level slurries.
Plate-type compound filter cloth for filtering actylcellulose size slurry divides three layers.
Ground floor: it is 168-172g/m that textile plain cloth specification is bleached in degreasing
2
The second layer: filter core.
(1) to bleach the nonwoven fabric specification of textile adhesive-free be 110 ± 5g/m in degreasing
2(one-level filter cloth) or 320 ± 10g/m
2(secondary filter cloth)
(2) to bleach textile short flannel slurry cypress plate specification be 125 ± 5g/m in degreasing
2(one-level filter cloth) or 340 ± 10g/m
2(secondary filter cloth)
(3) to bleach textile xylon slurry cypress specification be 140 ± 5g/m in degreasing
2(one-level filter cloth) or 360 ± 10g/m
2(secondary filter cloth).
The 3rd layer: it is 210 ± 5g/m that textile single face napping drillipg specification is bleached in degreasing
2
Bonding: as to coat the adhesive that is insoluble to acetone soln between the ground floor and the second layer, the second layer and the 3rd layer, and make after, the oven dry compound through heating.
Filter media material of the present invention is with careless and fine and closely woven combining, and each sheet compound filter cloth all is a rational filtration system.
The binder content that is insoluble to acetone in final products＜0.16%
The acetone extract thing in final products＜0.75%.
Bursting strength in final products＞26.7Kg/cm
2(380 pounds/square inch)
Material of the present invention is that degreasing bleached cotton fiber xylon has good antistatic performance, and through shrinkproof processing, shrinkproof ability is strong.
The present invention is further illustrated below in conjunction with drawings and Examples:
Fig. 1 is the structural representation of the embodiment of the invention
Fig. 2 is the plan view of Fig. 1
Plate-type compound filter cloth for filtering actylcellulose size slurry is the compound filter cloth of three-decker, comprises that textile layer of cloth 1,5 is bleached in degreasing up and down; Degreasing is bleached textile layer of cloth 1,5 through adhesive phase 2 and 4, with filter core 3; Pure nonwoven fabric or degreasing bleached cotton fiber, xylon slurry cypress plate, bonding are bleached in degreasing.
Filter core:
(1) the nonwoven step of textile adhesive-free is bleached in degreasing
(2) textile short flannel slurry cypress plate is bleached in degreasing
(3) degreasing bleaching xylon slurry cypress plate
Bonding:
Coat the adhesive that is not dissolved in acetone between the ground floor and the second layer, the second layer and the 3rd layer of each layer, make the plate-type compound filter cloth for filtering actylcellulose size slurry of three kinds of different filter cores after, the oven dry compound through heating.
Determine the position and the size 6 of punching (four) on filter cloth according to the model specification of plate and frame filter press.
In the present embodiment:
Ground floor: the textile white plain cloth specification of degreasing bleaching is 172 ± 5g/m
2
The second layer: filter core
(1) to bleach the nonwoven fabric specification of textile adhesive-free be 110 ± 5g/m in degreasing
2(one-level filter cloth) or 320 ± 10g/m
2(secondary filter cloth)
(2) to bleach textile short flannel slurry cypress plate specification be 125 ± 5g/m in degreasing
2(one-level filter cloth) or 340 ± 10g/m
2(secondary filter cloth)
(3) to bleach textile xylon slurry cypress specification be 140 ± 5g/m in degreasing
2(one-level filter cloth) or 360 ± 10g/m
2(secondary filter cloth)
The 3rd layer: it is 210 ± 5g/m that textile single face napping drillipg specification is bleached in degreasing
2
The bonding agent of bonding usefulness is that acetone solvent can not dissolve.
