They do not absorb water and atmospheric moisture from the air. They have sufficient mechanical strength, good sound and heat insulation; does not support combustion, does not contain heavy metals, harmless to the human body and the environment. Easy to process and adhere well. Welding and forming possible. The surface is suitable for self-adhesive films, silk-screen printing and UV printing. Transport and storage - Sheets should be stored in the manufacturer's packaging in warehouses at a temperature of no more than 40 ° C at a distance of at least 1 m from heating devices. - Sheets to be printed should be stored in a heated room on a flat surface in a horizontal position. - If the sheets were transported or stored at temperatures below 0 ° C, before unpacking and processing, they should be kept for at least 24 hours at room temperature. Preparation for work - Before printing, the surface of the sheet must be free of dust, dirt and moisture. - If there are visible contaminants on the surface of the sheet, it is recommended to blow the surface with ionized air or, if necessary, treat the surface with a cleaner based on an isopropyl alcohol solution. After using the cleaner, allow time to evaporate from the surface of the sheet. Recommended surface drying time after treatment with liquid cleaning agent is 10-20 minutes. - It is recommended to remove the protective film from the front surface of the sheet just before feeding the sheet to the printing equipment. - Before printing, it is recommended to remove excess static voltage from the surface of the PVC sheet ( ionization air guns, air knives and ionization nebulizers or by installing stationary electrostatic neutralizers). - It is recommended to handle the material with gloves to avoid fingerprints and, consequently, reduce print quality. Treatment - Printing on PVC sheets must be carried out in accordance with all the requirements of the supplier of printing equipment ( relative humidity of the room not less than 50%, air temperature 23 C o , or others specified in the instruction manual). - After printing with UV-curing ink, before further processing of sheets ( milling, bending, gluing, etc.), it is recommended to hold the product for 12 hours for the final polymerization of UV ink ( depending on the thickness of the printed layer). - A selection of optimal UV irradiation modes for each specific image is required: the appearance of the effect of stickiness of the printed surface indicates insufficient exposure time and ( or) the power of UV lamps; the appearance of the effect of fragility of the image or its shedding from the surface indicates an overabundance of the period and / or power of the radiation of UV lamps. - When subsequently fixing UV-printed PVC sheets with screws, screws, rivets, the coefficient of linear thermal expansion should be taken into account, depending on where the product will be used indoors or outdoors. - UV printing equipment suppliers recommend laminating prints that are prone to abrasion. Guarantees - To obtain the guaranteed expected result of printing on PVC sheets, it is necessary to carry out a test print. It is also necessary to carry out a full cycle of post-printing processing of PVC sheets, if such is provided for in the project of the final product ( production and approval of a pilot sample).
