Projection film coating method
Jun 02, 2018
The first step: clean the glass, inspect the glass with a spray bottle filled with cleaning solution to spray the wet glass surface, clean the glass with a hard scraper, water scraper wiper alternately, if necessary, can also use a blade to scrape the shovel attached dirt, supplemented with special Wipe the glass around the glass and carefully clean it until it is clean. Use tools: watering can, water scraper, special rag, blade, etc.
Precautions:
1. Dirt, dust, lint, etc. cannot be shovelled on the surface of the glass. Otherwise, tiny space will be created between the film and the glass, which can inhale air and cause damage to the film, thereby affecting the quality of the projection film and the beauty of the projection film.
2, it is best to use distilled water, purified water, or filtered tap water to reconcile the cleaning solution to avoid dust.
3. Prepare anti-fouling preparations at the installation site to prevent sewage from contaminating the walls.
The second step: the installation of the projection film
1. Remove the protective film by peeling off the film, spraying the mounting liquid on the exposed mounting surface and the clean glass surface, attaching the film mounting surface to the glass surface, and carefully floating the projection film.
2. After the wiper and bubble projection film is in place, spray the mounting liquid on the surface of the projection film immediately. Attach the clean protective film surface to the surface of the projection film. Spray the mounting solution again to lubricate the surface. Use a professional scraper. The water tool removes bubbles and mounting liquid from between the membrane and the glass. The first time the water is wiped lightly, and then the cross-wiper is continuously and forcefully applied. The upper side of the glass is preferably a horizontal wiper, and there is a cross-over wiper from below to above. Wipe the water from the middle and use the tool: soft handle, water scraper, watering can, etc.
Precautions:
1. Reactive water solution to avoid bubble and falling quality problems.
2. The filming process should have a clean work area, clean and free of dirt, to ensure that the film is clean.
3, cross wipe in an orderly direction, residual excess water and air bubbles will affect the quality of the film.
4, the plastic surface of the film can not touch any other place.
The third step: Trim the membrane edge and process the water stains. Carefully check the edges of the projection film. Use a scraper to squeeze the remaining film and air bubbles between the diaphragm and the glass. Press the edges to enhance the film edge adhesion. Four weeks cut. Utility tools: cutting knife, hard scraper and so on.
Matters needing attention: To avoid scratching the film surface, when necessary, use a non-woven fabric to cover the hard scraper.
Step 4: Level the membrane surface, check whether there are film defects, residual air bubbles and water stains, and loose viewing areas. Use a soft rag scraper or hard squeegee to gently expel bubbles. Give the glass and diaphragm stronger adhesion. Utility tools: hard scraper, watering can, etc.
