Application And Problems Of Thermosetting Ink

       Thermosetting ink, also known as plastic ink, or self-adhesive ink. Its ingredients: it is mainly composed of polyvinyl chloride (PVC) and phthalates, and the thermosetting ink is composed of polyvinyl chloride, phthalates, color fixing agent, stabilizer and thickener.Application And Problems Of Thermosetting Ink

Application And Problems Of Thermosetting Ink

       Thermosetting ink is a non solvent ink. After heating, it dissolves and plasticizes between powder and additives, infiltrates into the fiber and adheres closely with the cloth to form a firm film. Application And Problems Of Thermosetting Ink

       Due to the current restrictions on the use of polyvinyl chloride, polyvinyl chloride can be replaced by modifiers to make thermosetting inks that meet the requirements of environmental protection. Application And Problems Of Thermosetting Ink

        Because the plasticization temperature of PVC is different, thermosetting ink can be divided into high temperature and low temperature.Application And Problems Of Thermosetting Ink

      Thermosetting ink entered the market earlier, but its promotion speed is relatively slow due to the unfamiliar operation and the limitation of production equipment. Now it is very mature from its market promotion to production and operation.Application And Problems Of Thermosetting Ink

Basic requirements for thermosetting inks

      Polyester hard board shall be used for other boards, and hard type shall also be used for table board. Now tempered glass is more common, and the use of screen shall be flexibly applied according to the printed pattern. Application And Problems Of Thermosetting Ink

       For example, fine dot transition is recommended to be suitable for screen between 150 mesh and 250 mesh, and thermosetting ink itself has no requirements for photosensitive adhesive.Application And Problems Of Thermosetting Ink

       It is recommended to use water and oil for ordinary printing patterns. In this way, water or solvent can be used when wiping the plate.Application And Problems Of Thermosetting Ink

Three dimensional thick film printing pattern

       Use special thick film plate and photosensitive glue to make thick film?. The screen plate is coated with an ordinary thickness once, and the outside is coated with a round knife according to the pattern thickness at one time or with an ordinary sizing device for many times, and then placed in the plate drying box for 40, 50 and 60 minutes for exposure.Application And Problems Of Thermosetting Ink

         The exposure time must be tested due to different photosensitive adhesives and different exposure box power. After development, it must be placed in the plate drying box to dry the water at low temperature. Application And Problems Of Thermosetting Ink

       Do not expose to the sun when it is not dry. Temperature is the key to the performance of thermosetting ink characteristics. Therefore, it is recommended to use tunnel drying and heating equipment with good thermal insulation and stable heating constant temperature.Application And Problems Of Thermosetting Ink

Special additives for thermosetting ink

      Thermosetting ink is a very independent printing material. She has her own special printing auxiliaries. Such as diluent, thickener, softener, color fixing agent, etc. If there are many additives to be added or reduced during operation, Application And Problems Of Thermosetting Ink

       it is recommended to contact the manufacturer first. Listen to the suggestions before operation. Do not add or subtract additives without authorization according to experience, resulting in unnecessary waste and loss.Application And Problems Of Thermosetting Ink

Technology of thermosetting ink

Thermosetting ink can be divided into ordinary and special processes according to different printing effects.

       Ordinary printing process generally refers to simple, solid and line monochrome overprint printing. In addition to heating, this kind of process is no different from ordinary printing process.Application And Problems Of Thermosetting Ink

        It is easy to operate without wiping and plasticizing, and its properties are several times higher than those of water-based printing materials.Application And Problems Of Thermosetting Ink

Special printing process generally refers to three-dimensional printing, foaming printing, suede printing, gravel printing, wire drawing printing, etc.

       Three dimensional printing requires thermosetting ink and three-dimensional gel. For example, three-dimensional thermosetting special dry brush thick film. Application And Problems Of Thermosetting Ink

        After the printing pattern is plasticized, it has soft hand feeling, strong tensile strength, good washing fastness and clear 90 ° right angle contour.Application And Problems Of Thermosetting Ink

       It is suggested that the thickness of the film thick film plate should be lower than that of the printed pattern. In this way, the printing effect will be better and more ideal if it is printed in two to three times to meet the thickness required by the pattern.Application And Problems Of Thermosetting Ink

       The operation of special thermosetting ink effects such as foaming, suede, gravel and wire drawing is the same as that of ordinary thermosetting ink. The effect after printing depends on the amount of additives added.Application And Problems Of Thermosetting Ink

Grasp the curing temperature of curing ink

        The reason for most failure cases is that they do not grasp the curing temperature and time. For ordinary printing patterns, curing generally takes 170 ° – 180 ° timing for 1 minute. Application And Problems Of Thermosetting Ink

       For special printing patterns, curing generally requires pre drying for 100 ° / 30 seconds, and then enter the drying channel dryer for 170 ° – 180 ° for 1-2 minutes after surface drying.Application And Problems Of Thermosetting Ink

        (white surface cloth is easy to change color at high temperature, the temperature is appropriately reduced and the time is prolonged) in addition, thermosetting ink foaming is suitable for pressing and ironing with foaming machine, and the surface is more flat.Application And Problems Of Thermosetting Ink
