1. It is provided with anilox roller plus blade for coating mode, and also provided with many selection opportunities of anilox roller with various coating amount.
2. It is provided with separate five-section type constant temperature drying system using infrared stainless steel heating tube plus beating wind, as wellas adjustable interior circulation air draining and suction devices. It is advantageous in strong wind-exit and wind entrance, helping drying thoroughly.
four. Development of technology and efficiency products
However, in the face of the future, although it is impossible to comprehensively predict the development status of the tape industry or variety, the preconditions and planning blueprints are tightly bundled in the standard application specification of the processing application and adhesive arrangement combined with the medium. For example, new technology products automotive insulation paper (wear, light, sun, heat insulation), PVB color glass tape (color decoration, heat insulation, noise, earthquake blasting), environmentally friendly waterproof coating film (Computer drawing water ink compatible, waterproof and wearable), highway refraction film glass microbead composite tape (eye-catching refraction, temperature resistance, cold resistance, freeze resistance, acid resistance, anti-aging), digital camera waterproof high gloss photo paper (computer drawing water The development, processing and manufacturing of products such as ink compatibility, waterproof and abrasion resistance, high resolution, high reductiveness and long shelf life are all applications of media surface treatment technology. On the other hand, such as; aerospace equipment without media double-sided tape (high temperature resistant film), medical conductive tape (heart pulse electric shock and medical detector fixed), printed circuit board composite tape (high temperature, impact resistance), car Interior decorative panel (high temperature resistance, buffer safety, aesthetics), road marking tape (eye-catching, temperature-resistant, cold-resistant, freeze-resistant, acid-resistant, anti-aging), correction tape (shading, writing, ink absorption) (Sex), anti-counterfeiting and brittle tape (easy brittle, anti-counterfeiting, printing, shielding) and other products are subject to the technical transformation of the adhesive. However, if the basic structure of the two types of products is carefully summarized, the technical results formed on the basis of the adhesive application are only the technical process differences between the application process and the treatment, and the main surface function of the medium surface treatment or the adhesive is distinguished. In fact, most of the technical applications of various types of tape products are based on the application and function of adhesives.
Characteristics of several coating methods -
Hot melt adhesive coating
The coating device mainly heats and melts the solid type glue, and directly sprays the glue on the substrate through the coating die by hydraulic loading. Hot melt adhesive coating is a new technology developed in the past ten years. Hot melt adhesive coating does not require drying equipment and has low energy consumption. Hot melt adhesive is 100% solid rubber component and does not contain toxic organic solvents. Ordinary sizing coatings use toxic organic solvents (such as benzene) to dilute the glue, and the toxic gases caused by them are extremely harmful to the operator.
Hot melt adhesive coating has its unique advantages over conventional size coating. Hot melt adhesive coating is a green and environmentally friendly coating technology. It has high production speed, high efficiency, low cost, small equipment footprint and short investment recovery period. It is an economical investment project and has been widely used in packaging. , medicine, automotive, clothing, electronics and other industries. Hot melt adhesive coating has great market development prospects, and the development ratio of this technology in the market will become larger and larger, and new application fields will continue to emerge.
Squeegee method and application
In the coating process, the glue is often uneven, which requires a certain scraping mechanism to evenly scrape the glue. The scraping mechanism mainly includes a stainless steel scraper, a comma scraper, a scraping bar, a wire scraper, an air jet scraper, and the like.
