The practice shows that the epoxy resin can produce a number of substances of wood, metal, some plastics and other chemical bonds, so many dedicated screen ink is often used epoxy for the preparation of, Custom Nylon Flags in order to achieve the desired effect.
Impact ② solvent. Preparation of ink solvent also affect the results. Flag Manufacturers In China We know that the resin and solvent solubility parameters similar is appropriate, should also consider similar solubility parameters for the substrates. But also for the plastic screen inks from other silk screen effect to take into consideration (and other special inks should also be the case).
a. Resin and solvent solubility parameters are similar, which will help dissolve.
(b) plastic and plasticizer solubility parameters similar beneficial plasticized.
c ink solvents and plastic solubility parameters similar to fixed effects, Custom Nylon Flags but to prevent the erosion of the plastic surface too much ink solvent (or even cause the plastic to produce deformation).
d ink solvent, plasticizer solubility parameters similar could easily lead to plasticizer extraction or out.
e. The high boiling point solvent to use too much fixed effect decline. Custom Printed Flags Wholesale
f. Solvent selection of improper fixation is poor. Custom Nylon Flags The use of solvents from the many factors to consider, so the ink solvents often use three or more mixed solvent.
g. Solvent in the ink and links to materials (polymers) and substrate contacts, swelling and dissolution of the substrate surface, so the link to material interdiffusion, forming the boundary of the middle layer of mixed layer in the substrate and the ink led to the disappearance of the interface, forming a solid combination of inks and substrates. Custom Screen Printed Flags
The diffusion process is dissolved in the ink solvent on the substrate surface, while the substrates dissolved or not, depends on the link in the ink material and solvent polarity. Custom Nylon Flags Only the polarity of the ink and substrate can be dissolved only with adhesive fastness.
Link material in the ink is usually a macromolecular polymer of linear structure of its molecules at both ends is very easy to spread to the substrate, the short side chain is not conducive to the proliferation of large branches Figure 4-6 cloth acting hand dyeing device
Automatic and dyeing method. This mechanical, every year new varieties available, but their basic principle is the same. Run the layout of mechanical and dyeing machine is a version of the box move, on the contrary multicolor box for automatic and dyeing machines are fixed, while the fabric is a in the ring on the conveyor belt. Flag Company In China Version of the scraper, scraping moving in the same direction for the . After the completion of the , the version at the same time increased, Custom Nylon Flags detachment from the and dyeing cloth. At this time, and dyeing things move a certain distance, Service version and then at the same time decline to the Order of pollutants and dyeing. Wholesale Flags Suppliers Repeated this action to complete a continuous . The of the speed of such machines is generally 300 to
