1.The cause of a back adhesion:
(1)the paste itself anti-viscosity, especially in the wet weather easy to stick back;
(2)After the printing is completed, it is packaged without perfect heat treatment;
(3)adjust the slurry formula is not appropriate, adding too much transparent slurry easy to cause back adhesion;
(4)transport or storage conditions are not good, in high temperature, high humidity conditions for a long time stack.Treatment methods for back adhesion:
(1)choose good anti - sticky paste printing;2.Reasons for poor elasticity:
(1)The selection of sizing technology and printing fabric do not match;
(2)After printing drying treatment is not complete;
(3)too much crosslinking agent will affect the size of the elasticity and softness.
(4)add excessive destruction of resin tensile material (urea, ammonia).
3.Causes of color transfer phenomenon:
(1)when mixing the selection of color species poor resistance to migration;(4)transport or storage conditions are not good, in high temperature, high humidity conditions for a long time stack.
Treatment of color transfer phenomenon:
(1)selection of good color species resistant to migration to adjust the paste.Copyright © 2019 Anhui Sinograce Chemical Co., Ltd. | All Rights Reserved
