Description
Technical field
The invention belongs to pharmaceutical pack material technology field, be specifically related to a kind of lightweight pharmaceutical glass molded bottle and method for making thereof.
Background technology
Because pharmaceutical glass container production cost is higher, add that matter is heavy, shortcoming such as frangible, at some packaging field by metal vessel, plastic containers, replacements such as matrix material soft packaging, high-grade feeding solution is removed in the medical packaging field, infusion bottle, outside the cillin bottle, conventional packing has been Plastic Bottle, flexible pipe and Blister Package replace, for improving homemade pharmaceutical glass Bottle ﹠ Can quality scale, realize energy-saving and cost-reducing, the lightweight of glass packaging is exactly under the proof strength certain condition, reduces the weight capacity ratio of vial, and purpose is to improve its economy, the pharmaceutical glass packing must accelerate to implement lightweight, reduce cost, improve performance, could adapt to following industry development trend.
Summary of the invention
The invention provides a kind of lightweight pharmaceutical glass molded bottle and method for making thereof, purpose is to realize the pharmaceutical glass molded bottle lightweight, and the requirement of adaptation glass packaging market and greenization, rely on a series of physicochemical property such as glass material excellent chemical stability, resistance to air loss, clear transparent, high temperature resistant, easy sterilization simultaneously, promote pharmaceutical glass packing development form.It is about 1/4 that the more common mold-formed bottle bottle of this product heavily reduces, effectively save energy and raw materials consumption, thus reducing product cost, its performance index are better than common mold-formed bottle, and the market price is not higher than common mold-formed bottle.
A kind of lightweight mold-formed bottle is characterized in that, its material is counted with oxide compound according to weight percentage:
SiO
2?68-76％，Al
2O
3?1-4％，CaO?6-12％，MgO?1-4％，K
2O+Na
2O?11-17％，Fe
2O
3?0.05-0.1％；
Described lightweight mold-formed bottle is made by the raw material of following weight part:
Quartz sand 300-400 part, feldspar 60-70 part, calcite 60-65 part, rhombspar 40-50 part, soda ash 90-110 part, finings 1-5 part.
Described lightweight mold-formed bottle weight capacity ratio is 0.15～0.6, and wall thickness is 2-2.5mm.Weight capacity ratio is preferably 0.2～0.3.
The intrinsic strength of glass depends on the main component (prescription) of glass to a certain extent, and the packaging container glass mainly is NaO
2-CaO-SiO
2Be glass, the composition that the consideration of lightweight Glass Containers emphasis is gained in strength improves network former content in the composition, and it is close that glass structure more is becoming tight.It is high that the electric charge of the oxide ion of introducing in the composition is wanted, and ionic radius is little.
Described lightweight mold-formed bottle, its method for making comprises the steps:
1) batching
2) found: temperature of fusion is 1380 ℃-1560 ℃
3) feed
4) moulding
5) move back temperature
6) check and accept.
Compared with prior art, it is light that the common mold-formed bottle of lightweight mold-formed bottle weight ratio of the present invention is wanted, with 20mlA type mold-formed bottle is example, lightweight mold-formed bottle of the present invention (26.4 gram/only) alleviates 11 grams/only than conventional bottle (37.6 grams/only), thereby reduce starting material unit consumption level greatly, to strengthen the pharmaceutical glass product in pharmaceutical wrapping material competitive power.
Embodiment
Embodiment 1-3: prescription

4Deng), halogenide (as fluorochemical, muriate etc.) and compound clarifier etc.
Embodiment 4: method for making specifically comprises the steps:
1) batching: select among the embodiment 1-3 each prescription, with various raw material pulverizing, mix;
2) found: its process of founding is broadly divided into silicate formation, glass formation, clarification, homogenizing, 5 stages of cooling.This 5 stages are that the different sites at smelting furnace carries out, so that the glass melting temperature of segmentation precise control.Kiln operation process index stable most important, the fluctuation of general requirement temperature of fusion is no more than 10 ℃, and liquid fluctuating is no more than 0.5mm, and klin pressure fluctuation is no more than 2Pa, prevent that the kiln space from burning with anger, thereby prevent quality problems such as calculus, color, outward appearance, intensity difference.Very high during high-grade Light weight Container is produced to the fluctuation accuracy requirement of minute batching channel temp and metal level, have be controlled at respectively ± 2 ℃ with interior and ± 0.2mm in.For guaranteeing high-precision production technique index, use high temperature, wide cross section, large-scale roller bed type horse shoe flame smelting furnace.Kiln is carried out measures such as all risk insurance temperature, furnace bottom bubbling, electricity fusing-aid, weir, thermal parameter use microcomputer control, made melting rate reach 1.5～2.0 (tm-1), refining quality obviously improves.
3) feed
4) moulding: the production process of glasswork can be divided into moulding and two stages of typing.Moulding and typing are carried out continuously, in the moulding process, need the viscosity, temperature of feed glass and by mould medium heat passage towards periphery.Usually control forming operation from 3 characteristic temperature values: softening temperature, annealing temperature and strain point.Variant production is crucial by testing definite reasonable parameter, and advanced system bottle, feed and heating system and the advanced moulding process of employing are the acquisition uniform wall thickness, realize light-weighted basic assurance.
5) move back temperature: annealing is to eliminate or reduce residual stress in the glass to the heat treatment process of permissible value.Any glasswork all exists residual heat stress or permanent stress in the course of processing.In order to eliminate these thermal stresses, need with glass heats to annealing point be incubated, soaking, make the structure of glass inside be adjusted stress relief.
The annealing process of this product comprises heating, insulation, slowly cooling and 4 stages of fast cooling, and accurately controls soaking time according to wall thickness, and slowly temperature-fall period is wanted strict control cooling rate, in order to avoid produce new stress.In the fast cold stage, adopt different cooling rates according to wall thickness, the temporary stress that produces when preventing to lower the temperature surpasses the glass intensity limit and causes and break.
6) check and accept.
The step that can also comprise in the prior art other among the present invention, for example: coating.
