Abstract
A tranparency-adjustable film is composed of two pieces of transparent films and sealed along its periphery. At least one of inner surfaces of both films is made up of elastic and soft transparent matter and at least one of the inner surfaces is rough. Said film can be stuck onto surface of glass to make its transparency adjustable stepless. Its advantages are ideal transparency, simple structure and both manual and electric remote control.
Description
The invention belongs to the field of adjustable transparent film.
Along with modern life development, various window adjustable printing opacity technology are also developed step by step and apply.Wherein technical comparatively ripe structure is the container that two parallel transparent are formed, deposit transparency electrode on the inner surface of two parallel transparent, in container, add liquid crystal or contain the liquid of certain suspension, in case add voltage and between two plates, produce electric field at two plate electrodes, liquid crystal or the liquid that contains certain suspension just can change arrangement mode under electric field action, thereby caused the change of penetrability, this structure has uses advantages such as simple.But its expensive cost is its topmost shortcoming with not utilizing the existing glass transformation that has installed.And No. 92230239, Chinese patent, name is called " the portable windowpane light modulating device of double-deck Polarizer " and has proposed another dimming mode.This device has its certain characteristics, but still is subjected to many restrictions when reality is used.
The purpose of this invention is to provide the double-layer transparent film that a kind of periphery seals, change the method for making of monoblock film penetrability with the relative distance between the change bilayer film inside.
The present invention realizes as follows: in a space of being made up of the sealing of two transparent membrane peripheries, it is to make by having certain flexible soft and transparent material that two surfaces, inside of these two films have surface layer on one side at least, and it is irregular having a surface simultaneously at least.When to film is inner when communicating with the external world, two film inside surfaces are in the natural separation state, are irregular because film inside has a surface at least, inject light and are scattered when irregular surface and cause penetrability decline.When bleed in film inside, two film surfaces are close under the external atmospheric pressure effect, be close to the back gap disappearance of two films is integrated, and light can direct projection cause penetrability to increase.
The adjustable transparent film that adopts method of the present invention to make could be adhered to any glass surface, can make these glass have the function of adjustable transparent degree immediately.Bleed in film when needing direct light, exitting in film when not needing direct light gets final product.Have the translucent effect ideal, cheap, simple in structure, do not relate to when particularly various glass being changed into adjustable transparent existing Structural Engineering is transformed, have very strong practicality, can be applied in various occasions widely.The control structure of manually bleed venting or the electronic venting of adopting simultaneously of bleeding of electronic telecontrol is also very simple.
Embodiment further specifies the present invention below in conjunction with accompanying drawing:
A kind of structural representation that figure one is adopted when being to use the tunable optical glass that the inventive method makes.
Figure two is a kind of structure partial enlarged drawings that can progressively increase the adjustable transparent film of penetrability that the inventive method is made.
An adjustable transparent film is attached to wants the on glass of light modulation, wherein outer membrane 1 is for there to be the transparent material of certain degree of hardness to make, bottom film 2 is made for having certain flexible soft and transparent material, it simultaneously is bonded on the glass 3, the rough surface of another side, 1 and 2 periphery sealing has an aperture 4 at least on correct position, pipeline 5 communicates with light modulation film intermediate space by aperture 4, in pipeline 5 parallel connections return pump 6 and air release 7 is housed.When opening air release 7, there is in the middle of the light modulation film air to exist, the surface of film 1 and film 2 is in the natural separation state, injects light and is scattered when film 2 irregular surfaces and causes penetrability to descend, and corresponding glass 3 becomes opaque.Otherwise, shut air release 7, open return pump 6, air in the middle of the light modulation film is found time, 1 and 2 are close together under the external atmospheric pressure effect, be close to the back surface gap disappearance of two films is integrated, light can direct projection cause penetrability to increase, and corresponding glass 3 becomes transparent.
In partial enlarged drawing, having inside surface on one side at least on two inside surfaces 8 of adjustable transparent film and 9 is to make by having certain flexible soft and transparent material, it is irregular also having a surface at least, the frosted surface that this irregular surface can be similar frosted glass, also tapered bossy body 10 and being evenly distributed on any one surface of two inside surfaces, the tapered bossy body 10 among this figure is evenly distributed on 9 surface.Like this when beginning to extract the adjustable transparent film inner air out, two film surfaces 8 and 9 beginning mutual extrusion under the external atmospheric pressure effect because 10 be tapered bossy body, when extruding force than hour, 8 and 9 contact area is also less, and corresponding glazed area is also less.Along with the increase of pressure can cause the increase of glazed area, finally when the gap of two film surfaces 8 and 9 disappeared, whole film was transparent fully.Had from fully transparent to complete opaque step-less adjustment function.
Simultaneously, when making adjustable transparent film, the functional characteristics for outstanding various different materials also can adopt multi-level composite structure.For example extexine is hard wear-resisting transparent membrane, and two middle endosexines are for having certain flexible soft and transparent film, and outer bottom is tough and tensile transparent protective film.So that the convenient transportation of this product. install, have good durability, particularly have better dimming effect in use.
