Producing technology of silver-liner double-deck glass cup

Abstract

The invention relates to a producing technology of a glass cup, in particular to a producing technology of a silver-liner double-deck glass cup. The producing technology comprises the following steps of choosing a proper glass tube and a silver tube, heating the silver tube from the middle part of the silver tube, and conducting undercutting on the silver tube to form a liner which is closed at one end and opened at the other end; rotating the glass tube while conducting local heating on the middle of the glass tube till glass is softened, using a blade to conduct cutting to form two external cup bodies which have cup bottoms, covering the liner with the external cup bodies, conducting rotary heating on the liner and the external cup bodies so that the cup bottom is formed through firing, using a fire sprayer to conduct preheating on a cup rim of the glass cup, and then using a die to conduct compression moulding after the cup rim is burned and fused, conducting annealing treatment on the formed cup body to obtain a semi-finished product, and graving, grinding, polishing, cleaning the semi-finished product to obtain the silver-liner double-deck glass cup. The producing technology of the glass cup has the advantages of being outstanding in low energy consumption, simple in technology, and the produced glass cup has good impact resistance, weather fastness, heat resistance, and airtightness.

Description

technical field [0001] The invention relates to a production process of a glass, in particular to a production process of a double-layer glass with a silver liner. Background technique [0002] Existing glass can be divided into single layer glass, double layer glass and crystal glass etc. Double-layer glass, as the name suggests, is divided into two layers when the glass is made, which can play the role of heat preservation, heat insulation and anti-scalding when in use. Double-layer glass can be divided into vacuum and non-vacuum glass according to the type of interlayer. The raw material of the double-layer glass is high borosilicate glass, which is fired at a high temperature of more than 600 degrees. It is usually made of high borosilicate glass tubes, and the inner and outer tubes are baked by a sealing machine. It is a new type of environmentally friendly glass. , is favored by people. [0003] The Chinese patent No. 200610038473.6 discloses a double-layer vacuum g...

Problems solved by technology

[0005] Due to the bactericidal effect of anions, many double-layer silver liner glasses have emerged on the market. The existing double-layer silver liner glass production technology is cumbersome, and most of them are assembled, and the anti-beating ability is relatively weak. During the production process, the finished high-temperature double-layer glass is cooled in a natural state. Because of the fast cooling speed, the finished double-layer glass is prone to bursting or cracking, which wastes financial and material resources, increases production costs, and consumes a lot of energy. , How to promote the sustained and rapid development of glass cup production under low-carbon economic conditions is a question that people must think about
