Fire-retardant PVC projection screens are used in large cinemas, 3D, 4D, theaters, and auditoriums. According to national regulations, flammable products must be used in public places and areas with high human traffic. It is mandatory to add fire-retardant materials according to standards within the fabric, achieving a fire-retardant effect that meets the national B1 fire-retardant standard.
Bubble curtain is a commonly used projection screen, a cost-effective product with moderate materials and mature technology, suitable for various occasions. Due to the coating of optical crystal glass beads on the surface of the bubble curtain, the surface can feel the tiny beads falling off when touched with the hand.
Features of Glass Bead Screens
1. High gain, narrow field of view: The glass bead screen has a "light return property," meaning the reflected light returns along the direction of the incident light. This is one reason for its high gain.
2. High Luminance: Screen brightness coefficient gain over 2.6 times, featuring high resolution, excellent color fidelity, clear daylight imaging, and distinct focus with vitality.
3. Glass bead curtains feature characteristics such as moisture resistance, mold prevention, flame retardancy, and odorless.
Application Scenario
Ideal for multimedia classrooms, conference rooms, control rooms, and home theaters; due to the limited field of view, to achieve optimal results, the viewer's eye level should be at the same height as the projector; thus, placing the projector on a table is suitable, but not ideal for ceiling-mounted projectors.
The glass bead screen offers a variety of projection sizes, ranging from 40 inches to 200 inches.
Routine Maintenance
1. Bubble screens cannot be folded and should not be touched with fingers or sharp objects to prevent smudging.
2. Dust the curtain area with a feather duster; for heavier stains, use a blow gun or vacuum cleaner to remove surface dirt.
3. For stubborn oil stains, use a silk cloth dipped in distilled water, mixed with ammonia-based glass cleaner, and gently clean. Be sure to control the amount of cleaner to prevent uneven reflection on the projection screen due to excessive penetration.
