The clarification device 5, the top of the secondary homogenization and clarification device 5 is connected to the horizontal glass liquid conveying device 7, and the connection between the secondary homogenization and clarification device 5 and the glass liquid conveying device 7 is provided with a vacuum device 6, and the glass liquid conveying device The inner wall of 7 is ...

Embodiment 2

[0033] A method for producing fully fused glass by one-time compression molding of the back cover of a glass mobile phone, characterized in that it includes the following steps:

[0034] Step 1) Raw material feeding: first use the electric heating melting device (3) to raise the inner furnace temperature of the glass melting device (2) to above 800°C, and use the feeding device (1) to start feeding the mixture when the furnace temperature rises to above 850°C , the raw material components of the mixture include silica, boria, aluminum oxide, calcium oxide, sodium oxide, magnesium oxide, zinc oxide, zirconium dioxide, and the mixture is in parts by weight, and the raw material components include: 60 parts of silicon, 2 parts of boron oxide, 18 parts of aluminum oxide, 0.5 parts of calcium oxide, 15 parts of sodium oxide, 6 parts of magnesium oxide, 2 parts of zinc oxide, 2.5 parts of zirconium dioxide;

[0035] Step 3) Raw material melting: Use the electric heating melting devi...

Embodiment 3

[0039] The mixture is calculated in parts by weight, and the raw material components include: 65 parts of silicon dioxide, 2 parts of boron oxide, 18 parts of aluminum oxide, 0.5 part of calcium oxide, 15 parts of sodium oxide, 6 parts of magnesium oxide, 2 parts of zinc oxide, 2.5 parts of zirconium dioxide.

Abstract

The invention relates to a glass mobile phone rear cover plate one-step pressure forming all-electric melting glass furnace. An electric heating melting device is fixed to the inner wall of a glass melting device, a feeding device is installed at the top of the glass melting device, the bottom of the glass melting device is connected with a horizontally arranged feeding channel, the other end of the feeding channel is connected with a vertically upward arranged secondary homogenization and clarification device, the top of the secondary homogenization and clarification device is connected witha horizontal glass liquid conveying device, and a vacuum pumping device is arranged at the connection position between the secondary homogenization and clarification device and the glass liquid conveying device. The glass mobile phone rear cover plate one-step pressure forming all-electric melting glass furnace has the following beneficial effects that the mixture added by the feeding device is fused at high temperature under the action of the electric heating melting device, and the melting temperature can reach 1650-1680 DEG C, and the fused glass is refractory glass, mainly because the aluminum oxide content in the composition of the fused glass is up to 17%, and the melting temperature is required to be above 1650 DEG C, and the glass is kept at high temperature for a long time, fringes in the glass liquid are eliminated, and homogenized glass liquid is formed.

Description

technical field [0001] The invention relates to a fully electric melting glass kiln and method for one-time molding of a glass mobile phone back cover, belonging to the technical field of back cover glass production. Background technique [0002] Long before the advent of smartphones, old-fashioned feature phones basically used plastic backplanes such as ABS and PC, which have the advantages of strong plasticity, easy processing, easy coloring, and no signal shielding. Thermoplastics will become soft after being heated, and can be formed after being injected into the mold and cooled. The yield rate is high, which helps to reduce the cost of mobile phone research and development, production and manufacturing. But at the same time, plastics also have disadvantages such as poor hand feeling, heat dissipation effect and cheap look and feel. Moreover, the strength of plastic itself is low. In order to provide sufficient support and protection for the internal electronic componen...
