Abstract

The invention relates to the field of new glass materials, and in particular discloses a long-material glass for large bottles and jars and a preparation method thereof. The large bottle glass with long material is characterized in that it is made of the following effective materials in parts by weight: SiO 2 73‑74.50 parts, Al 2 o 3 1.50‑3.00 parts, Na 2 O 12.40‑16.00 parts, MgO 1.2‑2.66 parts, K 2 O 0-1.55 parts, CaO 5.9-7.1 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, the molding temperature range exceeds 300K, and semi-mechanized molding can be used. At the same time, the product has good material properties. Its Vickers microhardness is greater than 500Kg / mm 2 .

Description

[0001] (1) Technical field [0002] The invention relates to the field of new glass materials, in particular to a long-lasting glass for large bottles and jars 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 glass bottles and jars, according to ...
