Embodiment 1

[0034] The raw materials used are composed of 76.77 parts of quartz sand, 3.09 parts of aluminum hydroxide, 26.72 parts of sodium carbonate, 2.48 parts of magnesium oxide and 7.41 parts of calcium carbonate.

[0035] The specific steps of the manufacturing method are as follows:

[0036] (1) Accurately weigh and mix the raw materials according to the above, and melt and homogenize the batch materials in the kiln at 1823K;

[0037] (2) The glass melt obtained from step (1) flows to the working part through the forehearth, and the temperature drops to 1448K, and the viscosity is 10 2 Pa s;

[0038] (3) Pick out an appropriate amount of glass liquid through the blowing rod, and blow it into small bubbles with a wall thickness of about 5mm;

[0039] (4) Repeat step (3) several times, and when enough glass liquid (such as 5.5 kg) is dipped in the blowing rod, blow it up to the finished product specification in the mold at one time;

[0040] (5) Put the glass product obtained in ...

Abstract

The invention relates to the field of new glass materials, and particularly discloses a large bottle glass suitable for artificial molding and a preparation method thereof. The large bottle glass suitable for artificial molding is characterized in that it is prepared from the following effective materials in parts by weight: SiO 2 73‑78.23 parts, Al 2 o 3 1.50‑3.36 parts, Na 2 O 13.28‑16.00 parts, K 2 O 0-1.55 parts, MgO 1.99-2.66 parts, CaO 0.92-6.00 parts. The present invention does not use expensive or toxic raw materials, and has the characteristics of low cost and easy availability of raw materials. The glass has long material properties, and the molding temperature range exceeds 300K. At the same time, the product has good physical properties, and its Vickers microhardness More than 500Kg / mm 2 , Large bottle glass material suitable for artificial molding.

Description

[0001] (1) Technical field [0002] The invention relates to the field of new glass materials, in particular to a large bottle glass suitable for artificial molding and a preparation method thereof. [0003] (2) Background technology [0004] Glass bottles and jars are the most common type of daily necessities. They can be used as packaging containers for food, beverages and many products, and are widely used. According to the appearance shape, it can be divided into round, oval, square and special-shaped bottles, etc.; according to the size of the bottle mouth, it can be divided into small-mouth bottles and large-mouth bottles. The inner diameter of the mouth is less than 30mm, which is used to hold fluid products, while the latter refers to glass containers with a small difference between the diameter of the bottle mouth and the diameter of the bottle body, and is mainly used to hold semi-fluid and solid products. In the production process of bottle glass, according to the m...
