Automatic Sliding Doors can either be a single door sliding in one direction or bi-parting doors where each door leaf slides in the opposite direction. They are often used in grocery stores, entrances to shopping malls, hospitals and other applications where you want to provide your customers a hands free, safe and easy access to your building.
Hospitals
Airports
Retail centers
Pharmacies
Hotels
Grocery stores
Hardware stores
Sporting goods stores
And more
In addition, one of the biggest benefits of automatic doors is energy savings. Since these doors only open when someone comes in or out of your building, it prevents the loss of energy when a door may otherwise be left open for a long time.

(1) Lens cleaning: The lens paper is bent into several folds, soaked with a few drops of pure acetone; gently wipe the lens surface with wet lens paper, be careful not to press the lens with your fingers; repeat several times until the lens The surface is clean, free of dirt and traces of residue left in the mirror; dry with dry air; if necessary, wet the lens paper with a few drops of acetone into a rod, gently scrub the surface of the lens to remove heavy drops.
It is important to note that acetone absorbs moisture and moisture from the air, so acetone must be tightly capped. Do not pour the remaining acetone back into the new acetone bottle.
(2) Cleaning the mirror lens: remove the lens from the lens holder; put the lens on the mirror with the mirror face up; drop a few drops of acetone on the lens paper, and gently pull the lens paper over the mirror; repeat the above process, Until the mirror is clean, no stains or stains remain on the mirror; insert the lens into the lens holder.
If a molybdenum mirror is used as a mirror, because it cannot be plated, it can be used directly after polishing, so it can use water (soap water or detergent-containing water) to clean the mirror. However, other coated lenses cannot be cleaned with water because many of the coatings dissolve in water and the lenses will be damaged.
Most optical elements such as lenses and prisms are made of optical glass. Their optical surfaces are carefully ground and polished, and some or even multilayer films are plated. The optical properties (such as refractive index, reflectance, transmittance, etc.) of these components or their materials have certain requirements, and their mechanical and chemical properties may be poor. If they are not properly used and maintained, they may degrade the optical performance. Damage is scrapped. Common causes of damage are broken, worn, scratched, stained, moldy, and corrosive.
Daily maintenance of laser cutting machine optics
Once the laser cutting machine's optical components are contaminated or even stuck to small particles of cutting products, cleaning it is an extremely important and often overlooked issue. Here are some cleaning points:
