Restoration and protection of airplane glazing. Aircraft glazing, which is in a new state, is an integral and necessary part for normal piloting, and the transparency of the glazing is an important component of safe and comfortable control. Unlike automotive and window glass, aircraft glazing is made of transparent polycarbonate, which is lightweight and more resistant to dynamic and static loads than quartz glass. But for all its advantages, of course there are also disadvantages. Less resistance to abrasion, sandblasting and resistance to small and medium, and sometimes large, scratches! Static contributes to contamination, and insects adhering during flight require periodic cleaning of the glazing. But due to its instability to scratches, the glazing quickly becomes semi-matt glass. Replacing blisters and aircraft glazing is an expensive and not a quick undertaking, and not always a way out! Refurbishment polishing of aircraft glazing helps to get rid of unnecessary expenses, saves you money and allows you to significantly prolong the working and comfortable state of the glazing. The protective compounds, which are used to process aircraft blisters after restoration, provide high working properties for a sufficiently long period. The difficulty in polishing polycarbonate aircraft glass lies in the characteristics of the material and its performance. Car polishes are not suitable for this, since they significantly increase the risk of minus diopters, which distort the optical properties, and also do not allow achieving the necessary transparency in transmission in bright sunlight. It is also important that the partial inaccessibility of the restored surfaces of aircraft glazing, due to structural features, is not available for polishing without the use of a special tool. The materials we use for aircraft allow us to restore the transparency of aircraft glazing in a short time, and the hydrophobic protective compound on the outside and antistatic from the inside - to extend the consumer properties of the glasses for a sufficiently long period. Refurbishment polishing of aircraft glazing is performed in three stages and takes from one to three days. We order the materials used in polishing in Germany and Italy, since there are no such materials on sale on our market yet. The complexity of restorative polishing of aircraft blisters lies in the laboriousness of the process and the impossibility of making any mistake (replacing the blister). In the first stage, aircraft blisters are surface cleaned and deep-sanded to remove oxide deposits, insect marks and medium scratches and retouch large and deep scratches. After a short sanding, the technician wipes the surface to be treated and carefully checks the remaining scratches and transparency of the aircraft glass. This process is carried out from the outside and from the inside of the aircraft glazing until a clean, scratch-free surface appears using 3 polishes of different composition and grain. The next step in polishing aircraft blisters is the use of a polish specially made for polishing polycarbonate glass that does not have an abrasive. The acidic base of the polishing paste allows you to remove the smallest scratches and achieve perfect transparency of the glass surface. This polishing is also carried out on both sides, with constant monitoring during operation for overheating of the surface and the appearance of optical lenses, which is not permissible, because thermal haze and optical lenses that appeared during the polishing process cannot be removed and restored! The third and final stage of aircraft glazing polishing is degreasing and applying a protective compound to the surface. In this case, special liquids are used that do not contain solvents and alcohols that can burn or oxidize the surface. Protective compounds used on glass differ in their properties and composition. On the outside it is a polymer with a pronounced hydrophobic effect, and on the inside with antistatic and anti-scratch properties. The process of polymerization of protective compounds takes from 6 to 48 hours. Cosmetic polishing of aircraft glazing, outside and inside Restoration of medium complexity of aircraft glazing Deep restoration of aircraft glazing Application of special protective coatings for aircraft glazing Strong hydrophobic effect for aircraft blisters.
