In LCD panel manufacturing, chemical diaphragm pumps are mainly used to transport chemicals such as photoresist, developer, and stripper. These chemicals are critical to the quality and performance of LCD displays, so the transfer process needs to be precisely controlled to avoid the incorporation of impurities and air bubbles. Chemical diaphragm pumps can provide stable and reliable transmission to ensure the purity and uniformity of chemicals, thereby improving the quality and production efficiency of LCD displays.
