Основните фактори за равномерността на защитното филмово покритие са няколко условия, пряко свързани с процеса на покритие: покрит субстрат, лепило, стоманена валяк с покритие/гумена ролка, машина за ламиниране, etc.
Има много фактори, влияещи върху равномерността на покритието, включително оператори, машини, материали, методи, и пръстени, but the basic factors are several conditions directly related to the coating process: покрит субстрат, glue, coated steel Roller/rubber roller, and compound machine, etc.
1) Coating substrate: main material, surface characteristics, thickness, and uniformity, etc.
2) Adhesive: main working viscosity, affinity to the substrate surface, and so on.
3) Coating steel roller: It is not only the direct carrier of the adhesive, but also the support standard for the coated substrate and the rubber roller, so it is the core of the entire coating mechanism. Its shape and position tolerance, rigidity, dynamic and static balance quality, surface quality, temperature uniformity, and thermal deformation affect the uniformity of the coating.
4) Coating rubber roller: Coating roller is an important variable of coating quality, and its material (such as rubber layer life), hardness, form and position tolerance, rigidity, dynamic and static balance quality, surface quality, thermal deformation, etc. also affect To the uniformity of coating.
5) Laminating machine: It is the basic platform for coating. In addition to the precision and sensitivity of the coating steel roller and rubber roller pressing mechanism, it also includes the highest speed of design and the overall stability of the machine.
The horizontal and vertical factors that affect the uniformity of the coating are different, and the control measures are correspondingly different. In practice, it is not only related to machine design and manufacturing, but also related to operation and process control.
