Problems solved by technology

[0003] Ordinary silicate glass, the raw material of glass containers, contains a certain amount of lead oxide. If it is directly used to make tea sets, wine sets, and wine bottles, lead may enter the human body when people drink tea or wine. Although some of the lead can be excreted through feces and sweat, some of the lead will dissolve into the blood, hindering the synthesis of blood, leading to anemia, headache, dizziness, fatigue, drowsiness, constipation and limb pain, etc., which will cause arteriosclerosis, Peptic ulcer and fundus hemorrhage and other symptoms, so the importance of producing lead-free glass is on the agenda

Embodiment 1

[0016] Send the purchased lead-free white cullet, which accounts for 32% of the total amount, into a washing machine for repeated washing with high-pressure water, and then dry naturally after rinsing. The real estate quartz sand, 6.5% soda ash, 10.5% albite feldspar, 5.6% calcite, 0.2% sodium sulfate, and 0.2% cobalt powder are sent to the blender and evenly sent to the electric kiln; The temperature in the kiln is increased to 1550°C, and the temperature is maintained for 26 hours, so that the mixture reaches a molten state, and the lead-free glass melt is obtained, and the lead-free glass melt is sent to the blowing machine, and blown into various types of containers , the temperature is lowered to 1000°C, and the lead-free glass container is solidified; the cured lead-free glass container is naturally cooled to 750°C and then sent to the annealing box by a conveyor. When the temperature drops to 160°C, the annealing is completed, and the lead-free glass container is sent i...

Abstract

The present invention discloses a lead-free glass container produced though a thermal transfer printing process, and belongs to the field of glass manufacturing. According to the present invention, lead-free white broken glass, white quartz sand, soda ash, sodium feldspar, calcite, sodium sulfate, cobalt powder, and a heat-resistant substrate film with color pattern are adopted as raw materials, and lead-free glass container manufacturing and thermal transfer printing are performed to obtain the finished product. According to the present invention, the method has characteristics of simple production, less production steps, high efficiency, no pollution, small occupation area and less investment, the pattern printed on the glass container surface has characteristics of good adhesion, high gloss, clear pattern, accurate chromatic printing, bright color, safety and no toxicity, and after lettering is performed, oil spraying sand blasting, secondary injection molding and other post-treatments can be performed.

Description

technical field [0001] The invention belongs to the field of glass container manufacturing, and in particular relates to a method for producing lead-free glass containers by thermal transfer technology. Background technique [0002] Thermal transfer printing is an emerging printing process. The printing method of this process is divided into two parts: transfer film printing and transfer processing. Transfer film printing uses dot printing to pre-print the pattern on the film surface. The printed pattern is rich in layers, The color is bright, ever-changing, the color difference is small, the reproducibility is good, it can meet the requirements of the designer, and it is suitable for mass production. Transfer printing on the surface of the product, the ink layer and the surface of the product are melted into one after forming, lifelike and beautiful, greatly improving the grade of the product. The principle of thermal transfer printing is to print the color pattern on the ...
