Glass mold glass mold problem is storage and transportation problems, glassware mold surface after losing luster, loss of transparency, showing a rainbow, white or glass stick together easily separated. Glass mold can be divided into the following phases: 1. It begins - water or moisture adsorbed on the glass surface. 2. And then - water or moisture diffusion into the glass. 3. Secondly - glass surface layer soluble silicate is hydrolyzed and destruction. 4. Portland isolated SiO2 generated silica gel, glass surface protection film is formed, it prevents further erosion. 5. Caustic soda formed by hydrolysis, and the role of carbon dioxide in the air to generate sodium carbonate, gathered at the glass surface to form a surface film of soluble salts. Because of its strong hygroscopic, absorbing moisture and deliquescence, the final form of lye droplets. When the ambient temperature and humidity changes, and these droplets concentration also changes. If concentrated alkali glass droplets and long-term exposure, gelatinous silicone film may be partially dissolved therein, leaving the glass surface locally severe erosion, the formation of spots. This is the sodium ions migrate from the glass body out, the reaction of white alkali-rich plasma group with air. SEM can be observed particle swarm white. Identification and visual inspection methods moldy glass exterior morphology method is the most simple and feasible method. That concentration of light, the sample was placed in the reflected light and transmitted light was observed in the glass surface without spots and mist. These spots are indelible and mist with a cloth or water. Glass above phenomenon, showing a sample moldy. If the concentration of light, visually observed few minor spots and mist was moldy. If the concentration of light, the naked eye to a lot of spots and mist was a moderate mold. If, in the beam irradiation is no centralized, visual observation of some spots and mist is a serious mildew. Moldy also be under natural light, observed by spraying wet method. Glass mold to prevent the glass mold surface characteristics on the one hand and the glass itself is concerned, but also take the front glass packaging mildew treatment measures, packing seal level, storage and transportation conditions are closely related. Packed glass is subject to inventory, transportation after the user, sometimes for a long time. If you experience hot, humid season, when storage not, there may occur FCL glass mold. To prevent the glass mold, pay attention to the following aspects: ① fillers are separated by means of paper or cushion between mold powder or glass; ② usually stored in a well-ventilated warehouse; should not be stored in air-conditioned environment; ③ not allowed The glass box directly on the damp ground in the warehouse; ④ not allowed to be stored under the direct rays of the glass outdoors and sunlight.
