④ dry form and the resin. Ink drying depending on the type of resin, can also determine the form and drying methods, Flag Screen Printing see Table 3-9 "dry form of ink and resin.
Two. Introduced in accordance with the classification of the kinds of screen inks. Matching of inks and substrates, mainly determined by the adhesion, drying, and application functions. Often divided into the following types:
The ① plastic ink, the the the difficulties of plastic of yes the adhesion-Xing problem of the ink, Due to the very different of the the surface properties of of different plastic, therefore also is there are the of the plastic ink of different performance, Flag Screen Printing the ink used to the such as polyvinyl chloride of (PVC), Custom Car Window Flags , processing polyethylene (PE) and polypropylene (PP) with ink using ink, untreated PP, ABS, plexiglass and polystyrene (PS) ink, amino plastics ink, polyester (PET) with the ink, waterproof nylon fabric with ink, leather ( PU) with ink, polycarbonate (PC) and acetic acid fiber with ink, the wrinkle-free ultra-thin plastic with ink, vacuum forming plastic ink. The following is a brief ink of the two for vinyl products.
Table 3-9 dry form and the resin
The dry form of the main resin substrates use ratio (%)
Volatile dry type of vinyl chloride, acrylic, polyamide, cellulose, cyclized rubber, paper, Flag Screen Printing plastic 80 to 90
Water-based ink water-soluble acrylic acid ester of rosin, styrene acrylic, acrylic acid copolymer, paper, plastic 3 to 8
Oxidation of polymeric-modified alkyd resin plastic 5 to 15
Two liquid reaction type epoxy metal, baking coating the surface of 3 to 8
Heat curable epoxy metal baking for 1 to 2 of the coating surface
UV curable acrylic paper, plastic, 2 to 5
a. The soft vinyl products with ink. Ink, soft vinyl products mainly composed of ethylene resin, ketone solvents, aromatic solvents, paint by blending made.
Ethylene products of the soft to use ink, of the ink after membrane ink to has a excellent the performance of, Custom Motorcycle Flags of the acid resistance, of the ink alkali-resistant resistance, oil resistance is good, wear-resisting rub of Xing strong.
This ink to ketone solvents on the printed edition version of the film and scraper erosion, Flag Screen Printing plates and scraper by erosion, Bike Flags For Sale the accuracy will be reduced, resulting in the of quality, up to the precision of less than the required . Paid to the choice of a good resistance to ketone solvents plate materials in the production of plates. Attention to the selection of a good resistance to ketone solvents scratch version of the in order to ensure the accuracy of .
(b) rigid vinyl products with ink. Rigid vinyl products are common substrates. Ink rigid vinyl products are mainly three types: matt soft ink gloss inks; vinyl as the main ingredient; gloss inks to other resins as the main ingredient.
When the , usually according to the requirements of the substrates and conditions to select the ink. Ink, rigid vinyl products for plastic board, plastic board and plastic molding, such as .
The ② metal screen inks. Flag Screen Printing Such as the heatset metal ink aluminum anode oxidation at room temperature drying ink, etc.. The main requirements on the performance of metal ink is rubbing. Custom Car Mirror Flags
Metal ink and other inks. The ink used in metal oxidative polymerization type, evaporative drying, heat reactive and special ink.
a. Oxidation of polymeric ink. This type of ink easy, light resistance, attached to climate and strong and good color, the inadequacies of drying is slow, solvent resistance, heat resistance and poor.
