Glass bottle packaging lightweight design

Adjust the glass formula. Glass inner strength to some extent, depends on the main components of the glass ( The formula) , packing container glass mainly Na2O & ndash; CaO— SiO2 is glass, medicine, multi-purpose hard borosilicate glass. Lightweight glass container key consider increasing the strength of the component. Improve the network formation content in the form, make the glass structure more compact materials. Composition introduced in oxide ion charge, ionic radius is smaller.

lightweight structure design. Study the structure of the reasonable glass container wall thickness thinning, the glass container wall thickness decreases, the vertical load capacity is reduced, but the reasonable structure can make the uniform stress distribution, uniform cooling and increase the container & other; Elastic & throughout; Instead, so that the resistance to internal pressure strength and impact strength increased, so can take the following measures to ensure that the vertical load strength slightly reduce or not to be reduced.

glass bottle modelling is best height is not big, the closer the bottle type spherical, the better, and the line of bottle type is as simple as possible, with no sharp corners or sharp edges, with ease the transition between the parts of smooth lines; The bottle shape is cylindrical; The greater the radius of curvature of bottle shoulder line bottle shoulder structure; The bottle and the bottle gently transition of configuration is better. In addition, bottles mouth reinforcement ring to small as far as possible, or cancel the reinforcement ring; The bottleneck of small mouth bottles don't thin and long.

by means of optimization design. Using the optimization design, this paper discusses the best glass bottle type, small and large capacity of the weight of the glass container, reduce raw material consumption; By means of modern mold design, processing, production of high precision of container mould, ensure the container size precision, thus ensuring strength of container. By means of advanced theory and the modern, according to different parts of the bottle type of the stress, the accurate design of each part of the container wall thickness, thickness of do, reduce weight.

to use reinforcement technology process design. Strengthening production technology, the production process each link, from the raw material organization, ingredients, melting, forming, annealing and other links must be strictly controlled, the chemical and physical strengthening process and surface coating on strengthening method, etc. , on the premise of improving the physical and mechanical strength, make glass containers to attain the goal of lightweight thin wall. Therefore, must be specified at the design stage to strengthen technology.
