Historical Roots The origins of blowing can be traced back to around 3500 BCE, with early civilizations such as the Egyptians and Mesopotamians being among the first to master the craft. These ancient artisans created glass vessels that served both functional and decorative purposes, laying the foundation for the art of glasses blowing. Over time, […]
Raw Materials: The Foundation of Glass Production The production of glass begins with the careful selection of raw materials. The primary ingredient in glass manufacturing is silica, or silicon dioxide, which is typically sourced from sand. In addition to silica, other crucial ingredients include soda ash (sodium carbonate) and limestone (calcium carbonate). These materials are […]
Ancient Beginnings: The Birth of Glass The Origins of Glassmaking (3500 BCE)The origins of glassmaking can be traced back to around 3500 BCE, when ancient Egyptians discovered the basic method of producing glass by melting sand. The glass created during this period was rough and primarily used for decorative purposes, such as in tombs and […]
Selecting and Cutting the Glass Substrate The process begins with choosing the appropriate glass substrate, typically soda-lime glass or borosilicate glass, known for their optimal properties for touch screen applications. The glass is then cut to the desired size using a cutting machine equipped with a diamond-edged blade. This machine is meticulously programmed to cut […]
Selection of Raw Materials for Touch Screen Glass The chemical strengthening process begins with selecting high-quality raw materials, such as soda-lime glass or borosilicate glass, known for their superior chemical and thermal properties. These materials are mixed with various chemicals and additives to create a consistent glass formula. The formula is then melted in a […]
Selecting and Preparing Raw Materials The manufacturing process begins with the careful selection of raw materials, including silicon dioxide, soda ash, and limestone. These ingredients are mixed and then heated to extremely high temperatures, often exceeding 1400°C, to create molten glass. Known as the batch process, this step is fundamental in determining the final properties […]
Understanding Resistive Touch Screens Resistive touch screens, often referred to as resistive touch panels, operate using a flexible plastic sheet and a metal wire grid. Touching the screen brings the plastic sheet and wire grid into contact, altering the electrical resistance, which the device then detects. This relatively simple and cost-effective technology is popular in […]
