0.2-0.6 parts of PN-180 thinner is put into high speed blender, with 150 after stirring 10-15 minutes at a temperature of 100-140 DEG C
Purpose filter screen filtration obtains filtrate A, then filtrate A is coated uniformly on to the upper and lower surfaces of screen cloth, i.e. screen cloth has pre-processed
At；
The production of S2 adhesive plaster:
By suspension method -45-55 parts of polyvinyl chloride resin powder, 17-26 parts of ditridecyl phthalate, ethanedioic acid dioctyl ester 3.0-5.5
Part, 0.5-1.0 parts of epoxidized soybean oil, 2.0-7.0 parts of antimony oxide, 0.08-0.18 parts of ultraviolet absorbing agent, antioxidant
0.03-0.1 parts, 0.9-1.2 parts and magnesium hydroxide 4.5-5.0 parts of barium-zinc liquid stabilization agent put into high speed blender,
With the filter screen filtration of 150 mesh after being stirred 10-15 minutes at a temperature of 100-140 DEG C, liquor B is obtained, liquor B is then poured into two
In roller open mill, roll milling terminates after roll milling 10-15 minutes, obtains jelly, finally puts into jelly to calender, calendering
At adhesive plaster；
The fitting of S3 high temperature:
It is same three layers at fitting embossing device after screen cloth and the adhesive plaster coated in screen cloth upper and lower surface are sufficiently heated or preheated
When fit together, laminate pressure 3-5Mpa, obtains semi-finished product clamper screen cloth by 160-180 DEG C of binding temperature；
S4 embossing:
The semi-finished product clamper screen cloth that S3 is obtained is using embossing machine progress upper and lower surfaces embossing processing, the folder screen cloth after obtaining stamp,
Then the folder screen cloth after stamp is fully cooled sizing by chill roll；
Folder screen cloth surface treatment after S5 stamp:
The upper and lower surfaces of folder screen cloth after the stamp that S4 is obtained are handled using acrylic acid, surface treatment process are as follows: utilize surface
Processor carries out the surface treatment of product, and coating uses roller coating technology, and the mesh number of thin,tough silk mesh wheel is 80-100 mesh, and oven temperature is
140-160 DEG C, obtain finished product clamp screen cloth；
S6 volumes of sanction packed products:
The finished product clamp screen cloth that S5 is obtained is tested, is rolled into finished product.
