Abstract

The invention discloses a manufacturing method of a high-tempered antibacterial glass cup. The manufacturing method comprises the following steps: (1) cleaning: cleaning a semi-finished product high-silicon-boron glass cup; (2) spraying a toughening agent, namely atomizing and spraying a KNO3 solution to the inner surface and the outer surface of the glass cup, and drying; (3) annealing and tempering: heating the dried glass cup to an annealing temperature, and carrying out annealing treatment; (4) spraying an antibacterial agent, namely atomizing and spraying an AgNO3 solution on the surfaceof the annealed glass cup, and drying; (5) antibacterial treatment: heating the dried glass cup containing the antibacterial agent to a high temperature, and carrying out antibacterial treatment; (6)ultrasonic cleaning: subjecting the glass cup to ultrasonic cleaning after antibacterial treatment and drying the same. According to the manufacturing method, tempering and antibiosis of the high-silicon-boron glass cup can be achieved at the same time, the technological process is short in consumed time, and the production efficiency is high; the prepared high-tempered antibacterial glass cup ishigh in strength and good in impact resistance, and has good resistance to escherichia coli and staphylococcus aureus.

Description

technical field [0001] The invention belongs to the technical field of glassware, relates to a glassware surface treatment method, in particular to a manufacturing method of a highly tempered antibacterial glass. Background technique [0002] In the daily life environment, there are various bacteria, fungi and microorganisms, etc., which pose a great threat to human health and even life-threatening; in addition, bacteria can also cause food, medicine, etc. Large economic losses caused a variety of secondary disasters. With the improvement of people's living standards, people pay more attention to the living and working environment, especially the health and hygiene of eating utensils. Among them, glass is the most commonly used glassware in daily life. Therefore, endowing glass with an antibacterial function is of great significance to improving people's living standards and improving the general health of society. [0003] The traditional glass manufacturing process is g...
