Description

1 TARIFF A bird-friendly coating with UV and visible area activity. TECHNICAL AREA 5 The present invention includes a coating designed to prevent or reduce bird collisions. It is related to glass. STATE OF THE ART 10 Bird collisions with windows in buildings pose a significant problem. For example, in Chicago, certain buildings (such as skyscrapers) are located on migratory bird routes. This Birds flying along the roads repeatedly approach these buildings because they cannot see the building's windows. It is impactful. Therefore, especially during bird migration seasons, thousands of birds die. This results in a similar situation for birds living in environments such as forests or park areas. Buildings located in such areas cause the same problems for birds. Traditional ways to reduce bird collisions with windows include nets, stickers, or The use of frit is included. However, these solutions are not suitable due to their aesthetic impact on architecture and / or because of the 20 They are ineffective because they don't make the glass more visible to the birds. is being evaluated. EP3148948A1 is a glass unit designed to prevent or reduce bird strikes. It is related to publication EP3148948A1; In some example arrangements, the window has 25 panels spaced apart. It comprises an insulating glass (IG) window unit with first and second substrates, where At least one of the substrates is an ultraviolet (UV) reflector to reflect UV radiation. It supports the covering so that birds can see the window more easily. Make the window suitable for birds. By making them more visible, bird collisions and consequently bird deaths can be reduced. A BRIEF DESCRIPTION OF THE INVENTION The purpose of the invention is to prevent glass, which is used as a facade material in the architectural sector, from being damaged by birds. The aim is to prevent or reduce bird strikes by making them visible. 35 To achieve the aforementioned purpose, the invention involves a glass substrate, provided on the glass substrate... A glass with a UV reflective coating to reduce or prevent bird strikes. 2 It is also related that the reflective coating applied to the glass substrate is three-layered and consists of two layers. This means that one layer contains titanium oxide and the other layer contains niobium oxide. The windows provide high visibility for birds and are therefore detectable by birds. with a coating structure that is imperceptible to humans, bird strikes or bird deaths are prevented. 5 In a preferred configuration of the invention, a first layer of titanium is adjacent to a glass substrate. It contains titanium oxide. Thanks to the use of titanium oxide, the first layer of the glass has a high index. It is ensured that it has a fracture. In a preferred configuration of the invention, the thickness of the first layer is in the range of 5-9 nm. This is achieved through a temperable coating and a glass softening temperature above 650 degrees. During this process, titanium oxide crystallizes at these temperatures; therefore, temperatures above 9 nm are avoided. Excessive use leads to malfunctions. In a preferred configuration of the invention, the refractive index of the first layer is in the range of 2.45-2.55. is happening. In a preferred configuration of the invention, a second layer is adjacent to the first layer. It contains niobium oxide. Therefore, using NbOx at these thicknesses allows for the desired UV 20 protection. The reflectivity value is obtained. In a preferred configuration of the invention, the thickness of the second layer is in the range of 17-23 nm. is happening. In a preferred configuration of the invention, the refractive index of the second layer is between 2.3 and 2.4. is happening. In a preferred configuration of the invention, a third layer is adjacent to the second layer. It contains titanium oxide. TiOx has been chosen as the protective layer. Thus, mechanical 30 and ensures the first percentage of use of environmentally resistant structures in architecture. In a preferred configuration of the invention, the thickness of the third layer is in the range of 5-9 nm. is happening. 35 In a preferred configuration of the invention, the refractive index of the third hash is 2.45-2.55. It is within this range. 3 In a preferred configuration of the invention, the glass substrate is a lime-soda glass. In a preferred configuration of the invention, the visible region transmittance of the glass is 70% and It is located on 5. In a preferred configuration of the invention, the amount of reflection in the UV region is between 35% and 45%. It falls within this range. This allows the desired UV reflectivity value to be achieved. In a preferred configuration of the invention, 10 periodically arranged particles are placed on a glass substrate. This provides a pattern. In this way, the bird-friendly glass improves bird visibility, allowing birds to see better. This helps to prevent collisions.

DETAILED DESCRIPTION OF THE INVENTION In this detailed description, the subject matter of the invention is developed without any restrictions and 30 The explanation is given with references to examples simply to better illustrate the topic. A glass substrate contains glass substrates, and at least one of the substrates is more suitable for a bird. with an ultraviolet (UV) reflective coating to reflect UV radiation so that it can be easily seen. is coated. In the preferred configuration, 35 of the glass is on an outer surface exposed to the atmosphere. The glass is made more visible to birds by applying a UV reflective coating. By making them more visible to birds, bird collisions and consequently bird deaths are reduced. 4 This can be reduced. In some sample arrangements, the primary substrate emits at least some infrared radiation. a solar management coating (e.g., low-E coating) to block (IR) radiation and a UV light to reflect UV radiation to make the window more visible to birds It uses reflective blocking coatings. Some examples to reduce bird collisions. In regulations, low-E coatings have an emission level not greater than 0.10 (En) and / or 8 5 It may have a sheet resistance (Rs) not greater than ohm / squared. Specific example According to regulations, UV reflective coatings must block at least UV radiation in the 350-440 nm range. 38% preferred at least 40%, more preferred at least 55%, most preferred at least It can block 60% and probably at least 65%. This makes the glass more visible to birds. and thus, to prevent or reduce bird collisions, commercial or residential applications 10 It increases the UV reflection of the window unit. Here, such coatings... Its use is typical of raw uncoated plate glass in the 300-440 nm range of the spectrum.
