Description

 Method and system for manufacturing optical functional film  

This invention relates to optical components and, more particularly, to a method and system for making a functional plastic film, functional polymeric film or functional PVA film.

As is generally known, ultraviolet (UV) light emitted from a high intensity source can cause severe corneal burns. Therefore, our eyes need protection to avoid these harmful ultraviolet light. In other special cases, our eyes absolutely need protection. Avoid ultraviolet light. When welding, expose to sunlight that is more than 5,000 feet (1524 meters) high, when the sun shines on snow or water, or sunbathing, etc. Time.

Not only ultraviolet rays, but also infrared rays are harmful. Wireless communications, household appliances, computers and lights emit varying levels of harmful radiation. In fact, there are also many natural infrared rays, such as those from the sun. Sunlight consists of thermal spectral radiation that is slightly larger than half infrared. At noon, the sun radiates about 1 kW/m2 of irradiance at sea level, of which 527 watts are infrared radiation. Once the sun's rays reach the surface of the earth, almost all of the heat radiation is infrared.

The energy of the sun on the ground can be divided into about 3% of ultraviolet rays (UV), 44% of visible light and 53% of infrared (IR). Therefore, when exposed to strong sunlight for a long period of time without protection, the human eye may experience a burning or stinging sensation, often accompanied by fatigue. This discomfort is particularly noticeable for those wearing contact lenses because the infrared rays can be absorbed by the contact lenses, causing them to "preheat". Ophthalmologists always encourage the habit of wearing sunglasses for a period of time in the sun.

Traditionally, to protect the lens from harmful rays from the source, the lens must be coated with one or more layers of IR and/or visible dye. Typically, soluble dyes and/or metal oxide pigments are used to coat the lens to absorb or reflect light at certain frequencies, such as IR frequencies, UV frequencies, and the like. Thus, the coated lens can reduce or alleviate eye diseases such as cataracts and glaucoma.

Due to the importance of sunglasses and protective glasses, many coating techniques exist today by immersing or spraying IR solvents or visible dyes into the lenses. However, since most lenses are curved, the curvature of the lens has significant hurdles in the application of IR solvents or visible dyes because the coating may be non-uniform. Therefore, the uneven coating on the curved lens surface greatly reduces the effectiveness of the protective layer.

When using conventional methods such as compression molding or injection, IR solvents or visible dyes are added during processing. Compression molding is a technique used to create objects that have a fixed cross-sectional profile. The material is pushed or pulled through the mold of the desired cross section. In the plastic extrusion process, the plastic is first melted into a viscous semi-liquid state. After softening, the plastic is compression molded from the contour. Using this technique, a curved lens can be created by pushing a softened optical film through the opening of the contour.

Injection molding is a manufacturing method of manufacturing a part by injecting a material into a mold. The material of the part is fed into a heated bucket, mixed and forced into the mold cavity where it is allowed to cool and solidify into the configuration of the cavity. For optical plastic films, both compression molding and injection methods require heating to soften the plastic film so that it can be bent. Since the dye is sensitive to heat, dye degradation occurs and the effect of protecting the eye is lowered.

Another problem with these IR solvent or visible dye coated lenses is that they are easily scratched and resistant to chemicals. Over time, the protective layer gradually loses its effectiveness and becomes harmful if not detected and replaced. To overcome these problems, lens manufacturers typically spray, dipped or inject another protective layer onto the lens. However, the additional layer makes the lens thicker and has a minimum thickness, posing an obstacle to eyeglass design and comfort.

Moreover, conventional methods of injection or compression molding are less aesthetically pleasing because infrared dyes appear green in such coatings. To counteract this unsightly green color, a gray color is usually additionally added to the PVA film. However, such an addition of gray reduces the penetration of light and thus reduces lens visibility. Finally, the addition of a gray color to the PVA film on the lens results in an increase in the cost of the lens, resulting in a higher cost of the final product. Therefore, materials and manufacturing methods for inexpensive and fast IR absorbing lenses are now desired.

Recently, in order to overcome the disadvantages of compression molding and injection methods, a more preferred solution casting method has been invented and extended. This solution casting technique is unique in that it does not require the application of conventional compression molding and injection molding techniques, but rather relatively easily includes the components and features produced by these processes. The method uses a mandrel or inner diameter mold that is immersed in a polymer solution tank or a liquid plastic tank that is specifically designed for the process. Due to the combination of heat and friction properties, the polymer solution forms a film around the mold. The film is then removed from the tank or tank in a precisely controlled manner and then subjected to a curing or drying process.

Other casting devices for solution casting methods can be belt or drum machines. Typically, the support strip has a width of 1.0 to 2.0 m and a length of 10 to 100 m. In the case of stainless steel, the thickness is between 1.0 and 2.0 mm. The drum type is usually 4 to 8 meters in diameter and 1.20 to 1.50 meters in width. The belt passage allows air flow to flow in the machine direction or in the opposite direction. The drum type is in a sealed form to prevent the steam from being released and to direct the airflow against the direction of the drum movement. One of the two pulleys or rollers is connected to a drive that requires very precise speed control to avoid any slight speed changes. The other roller is connected to a servo system that adjusts the belt tension to ensure smoothness of the belt and belt movement (vibration) and to control the expansion and expansion of the belt due to temperature changes. The belt conveyor has a guiding system to prevent the belt from shifting during operation. The belt is guided by the leveling movement of the support drum. Many different support materials have been used for belts such as copper, silver plated copper, chrome plated steel, stainless steel, polyvinyl alcohol or gelatin coated metal, polyester film, PTFE film and other polymer films. The most common support materials currently available are stainless steel and chrome-plated surfaces. Important items for belts and rollers are the thermal conductivity of the material, the technical process used to produce the desired surface finish, and the option to repair small surface defects. This casting technique allows for the simple production of films with structured surfaces. The belt surface is a replica of a precise film. This technology uses a roller or belt to produce a high gloss, structural or matte film surface treatment technology.

Once the first layer of the film is properly cured, a second functional property can be added to the product, such as a braided or coiled wire, a laser-cut hypotube or an engineered metal reinforcement to prevent kinking or imaging specific to the intended medical application. Target. Multiple casting steps can then be repeated to encapsulate the reinforcement, establish wall thickness, add additional lumens and optimize column strength. After curing or curing, it is taken out of the mold. The process works with a solvent polymer in liquid form without excessive heat to cure the part. Since the method uses centrifugal force to mold the part, it has the correct fluidity ratio, and a very thin IR or visible dye solution can be added to the optical film without using excessive heat.

Another method of making a film is an electrostatic method such as cavity molding or sheet casting or the like.
