Industrial equipment protection: Analysis of the wear and scratch resistance of EVA transparent film
The protective ability of EVA transparent film comes from its unique material properties. As an ethylene-vinyl acetate copolymer product, it can maintain transparency while improving the intermolecular bonding force by adjusting the vinyl acetate content. The surface hardness of high-quality EVA film can reach 2H pencil hardness (industry test standard), and daily tools or dust friction will not leave marks. The elastic components in its molecular structure can also absorb impact force. When it is slightly hit, the film layer will disperse stress through deformation to avoid damage to the equipment body.
In actual applications, the wear resistance of EVA transparent film far exceeds that of traditional protective materials. Comparative experiments show that under the same friction conditions (500g weight loading, reciprocating friction of cotton cloth), ordinary PE film becomes obviously white after 300 times, while EVA transparent film remains transparent after 1000 times of friction. The practice of a certain automobile parts factory has proved that after the EVA film is applied to the display screen of the testing instrument, the surface scratch rate is reduced from 23% to 1.5% per month, and the equipment maintenance cycle is extended by more than 3 times.
More importantly, the protection of EVA transparent film does not affect the use of equipment. Its light transmittance is over 90%, which will not interfere with the display reading; its thickness is only 0.1-0.3 mm, which does not affect the operating feel after lamination. During construction, electrostatic adsorption or low-viscosity layer design is used, which can not only fit tightly to the surface of the equipment, but also can be removed and replaced at any time to avoid residual glue stains from damaging the equipment.
From precision instruments in electronic workshops to heavy machine tools in workshops, EVA transparent film builds an invisible barrier for industrial equipment with "visible protection and tangible durability". It not only reduces the cost of equipment renovation, but also ensures operational stability by maintaining the integrity of the surface. In the industrial field that pursues efficient production, this practical and economical protection solution is becoming a new choice for equipment maintenance.
