The first to design determined and manufacturing mould, glass raw m"aterials with quartz sand as the main raw material, other acce₹ssories plus under high temperature melted into liquid,≈ and then injected into the mold, cooling, incision, back to the ₽fire, on the formation of glass bottle. Glass bottles are generally just signs, signs are also made by the die shape. Molding ↔glass bottle according to the production method can be divided into artifi♥cial blowing, blowing and extrusion molding machine thr↓ee. In accordance with the composition of glass bottles can be divided into the followπing categories: one is sodium glass two is lead glass three borosilicate g§lass
The main raw materials of glass bottles is natural ore, quartz stone≈, limestone, soda. Glass bottle with a high degree of transparency and corrosion resistance, c¶ontact with most of the chemicals will not change the properties of materials. Its simple man§ufacturing process, modeling various free, high hardness, heat resistance, clean, easy to clΩean, and has the characteristics of repeated use etc.. ✘Glass bottles as packaging material mainly used in∞ food, oil, wine, beverage, condiment, cosmetics and liquid chemical product, use i≠s very extensive. But the glass bottle also has its disadvantages, such as heavy weight↕, high cost, transportation and storage are not resistant to impact etc..
Using the characteristics and types of glass bottles: glass bottles is the main pa¶ckaging container of food, medicine, chemical industry. Th×ey have good chemical stability; easy to seal, good air ti∑ghtness, transparent, can observe the contained objects from the outside; stability; smooth ±surface, easy disinfection and sterilization; beautiful appearance, rich and colo₩rful decoration; there are certain mechanical strength, able to bear external force the pressure in the bottle and in the process of transportation and distri¥bution of raw material; broad, low cost etc.. Its disadvantage is the quality of large (quality and large capacity, high brittleness♥, brittle). However, in recent years, using the new technology of thin-walled£ lightweight and physical chemical tempering, these shortcomi ngs have significantly improved, thus the glass bottle can be plasti×c, iron, tin listen to the fierce competition, production increased year by ye®ar.
Glass bottle variety, from the big bottle of capacity of 1ML vial®s to ten liters, from the round, square, to the abnormity and shank bottle, from the shade≈ bottle of colorless transparent amber, green, blue, black and opaqu♣e opacified glass bottles, be too numerous to enumerate. The manufacturing process, glass b¶ottles are generally divided into the molded bottles (using the mo♥del bottle) and control bottles (with glass vials) two categories. Molded bottles and di vided into big mouth bottle (bottle more than 30MM in diameter) and small bottle of two class. T>he former is used for holding powder, bulk and paste material, which is used for conta ining liquid. According to the mouth of the bottle into the form of corks, screw bottle÷, bottle, bottle frosted bottle rolling table etc.. According to the using situati$on for the use of a time that is abandoned "a bottle" and used repeatedly "r↔ecovery bottle". According to the containing object classificat£ion, can be divided into bottles, beverage bottles, bottles, cans, bottles,• medicine bottles, acid reagent bottles, infusion bottles, cosmeti↔cs bottles etc.. |
