Problems solved by technology

[0005] At present, most of the existing antibacterial cups in the industry are silver-plated or coated silver: the treated glass has a small amount of active nano-silver and weak antibacterial ability; the coating is easy to fall off, and the heavy metals in the water are easy to exceed the standard. Although it has antibacterial effect, However, it is easy to be poisoned by heavy metals; in addition, the glass cup is not easy to handle, easy to break, and the production efficiency is low

Embodiment Construction

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below.

[0030] A method for manufacturing a glass cup with antibacterial and thermal shock resistance, comprising the steps of:

[0031] 1) Preparation of liner heat insulating agent: silver nitrate, potassium chloride, aluminum oxide, sodium silicate or mixed with each other;

[0032] 2) Coating heat-insulating agent on the inner tank: after three coatings and three drying steps, first coat silver nitrate on the inner tank of the cup and dry; then coat potassium chloride and dry; finally coat sodium silicate mixture and dry;

[0033] 3) Firing of the cup body: Put the cup shell and liner on the rolling machine and burn it into a double-layer semi-finished high borosilicate glass cup for use;

[0034] 4), selection and preparation of antibacterial agent salt: the salt is one or more of sulfates, nitrates, chlorides, carbonates and hydroxides containing alkali m...

Abstract

The invention discloses a manufacturing method of a glass cup with antibiosis and cold and hot impact resistance, which comprises the following steps: preparing an inner container heat insulation agent, coating the inner container with the heat insulation agent, firing a cup body, selecting and preparing antibacterial agent salt, cleaning the cup body, preheating the cup body, resisting bacteria, annealing and tempering, cleaning, drying and the like. The quantity of active nano-silver in the glass cup treated by adopting the method is large, and the antibacterial capability is enhanced; the coating is not easy to fall off, so that heavy metals in water are prevented from exceeding the standard, and heavy metal poisoning is avoided; in addition, the glass cup has a cold and hot impact resistance function, is easy to process, cannot be broken, reduces the defective rate and greatly improves the production efficiency.

Description

Technical field: [0001] The invention relates to a daily necessities cup, in particular to a method for manufacturing a glass cup with antibacterial properties and resistance to cold and heat shocks. Background technique: [0002] Antibacterial glass is glass that contains silver ions on the surface. Silver ions can adsorb bacteria. After the bacteria are adsorbed by silver ions, the enzymes that play a role in respiration will lose their effectiveness, the reproduction of bacteria will be inhibited, and they will die quickly. Silver ions have very strong inhibitory and killing effects on common Gram-positive and negative bacteria. Normally, >95% of coliform bacteria can be effectively killed within 2 hours, and >90% of Staphylococcus aureus can be effectively killed within 4 hours. [0003] There is a layer of oxide on the surface of metal particles. Silver oxide will be hydrolyzed into silver ions and hydroxide ions in water. The dissolved silver ions are the sourc...
