Automatic Film Applicator is a key equipment widely used in various industrial fields, especially plays an important role in the gluing process of fiber cloth. As an important composite substrate, the surface coating of fiber cloth not only affects the bonding performance of the material, but also directly affects the mass and performance of the final product. This paper will explore the experimental technology of Automatic Film Applicator gluing on fiber cloth, including equipment principle, coating process, parameter adjustment and application cases.
Automatic Film Applicator is a device used to uniformly Spreader Glue or Coating on the surface of a substrate. Its main components include:
Spreader Head and Spreader Roller: Used to transfer the glue from the storage tank to the substrate surface and ensure uniform Spreader.
Conveying system: Conveying substrates (e.g. fiber cloth) to the Spreader area and controlling their movement speed to ensure Spreader uniformity.
Drying System: The glue used to quickly cure and dry the Spreader on the substrate, usually including hot air or UV curing systems.
Control system: Monitor and adjust key parameters such as Spreader speed, thickness, drying temperature to ensure coating mass and product Stability.
Fiber cloth is a substrate material woven or woven from fiber materials. It has the advantages of light weight, high strength and good flexibility, so it is widely used in composites, building materials, automotive industry and other fields. Coating with glue or coating can improve its surface performance, enhance its adhesion, water resistance or corrosion resistance, and also provide a foundation for subsequent processing and application.
1. Preparation
Before conducting the Automatic Film Applicator experiment, you first need to prepare the following tasks:
Fiber cloth substrate: choose the appropriate fiber cloth as the coating substrate, considering its fiber type, density and surface preparation.
Glue or Coating: Choose the appropriate glue or Coating according to the coating needs, considering its viscosity, curing method (heat curing, UV curing, etc.) and film formation performance.
Coater and related equipment: Ensure the normal operation of the coater and perform the necessary calibrating and debugging to ensure the Stability and repeatability of the experiment.
2. Coating process
The coating process typically involves the following steps:
Substrate loading: Load the pre-cut fabric into the conveyor system to ensure that the fabric is flat and aligned with the Spreader area.
Glue Preparation: Place the selected glue or coating in the storage tank of the coater and deliver the glue to the Spreader head through a pumping system.
Spreader operation: Spreader head uniformly Spreader the glue on the surface of the fiber cloth. The speed of movement of the Spreader head and the pressure of the Spreader affect the thickness and uniformity of the Spreader layer.
Drying curing: Spreader the fiber cloth through the drying system, usually hot air or ultraviolet, quick curing glue and ensure that it adheres to the fiber cloth.
3. Parameter adjustment and optimization
Key parameters in the Spreader process include:
Spreader speed: affects the thickness of the Spreader layer, usually controlled by adjusting the traverse speed of the Spreader head.
Spreader Pressure: Ensure that the glue is evenly applied to the surface of the fabric without damaging the substrate.
Drying temperature and time: Ensure that the glue is cured quickly to avoid unnecessary problems caused by too long or too short curing time.
By precisely adjusting and optimizing these parameters, the ideal thickness and uniformity of the coating layer can be achieved, thereby improving the surface performance and processing efficiency of the fiber cloth.
The application cases of Automatic Film Applicator in the process of fiber coating mainly include:
Composite Preparative: Reinforced fiber cloth is coated with Resin, preparing high strength and lightweight composite parts.
Water proofer: coating waterproof glue or Coating, improve the waterproof performance of fiber cloth, for roof or wall waterproof treatment.
Automotive interior: Spreader the surface preparation agent on the fiber cloth to improve its Abrasion Resistance and easy cleaning, for car seats and other interior parts.
