What is the material of the essential oil bottle? How to solve the fragile problem?
As we all know, the main characteristics of glass materials for cosmetic packaging essential oil bottles are: harmless and odorless; non-toxic and odorless. Transparent, beautiful, good barrier performance, airtight, rich in raw materials, the essential oil bottle glass material is cheap and can be used multiple times. The bottle has the advantages of heat resistance, pressure resistance and cleaning resistance, and can be sterilized at high temperature or stored at low temperature. The main raw materials of essential oil bottle glass materials are natural ore, quartz stone, caustic soda, limestone, etc. The essential oil bottle glass material has high transparency and corrosion resistance, and the material properties in contact with the glass will not change. However, essential oil bottle glass materials also have their disadvantages, such as heavy weight, high transportation and storage costs, impact resistance and brittleness. Fragility is a problem when using essential oil bottle glass materials, which makes glass essential oil bottles greatly limited in daily use. So, how to solve the problem of fragile essential oil bottles made of glass? The essential oil bottle glass material is hard but fragile, with good transparency, high temperature resistance, corrosion resistance and other properties; at the same time, the steel is hard and not brittle, and has the characteristics of high temperature resistance. Therefore, people began to think that it would be useful if a glass could be made that had both glass hardness, high temperature resistance, corrosion resistance, and the properties of being as hard and unbreakable as steel. Fragile problems of essential oil bottles made of glass material. That is, fiber reinforced plastic, usually refers to the unsaturated polyester, epoxy resin and phenolic resin matrix reinforced with glass fiber, and the reinforced plastic that uses glass fiber or its product as a reinforcing material is called glass fiber reinforced plastic or glass fiber reinforced plastic. Because of the different types of resins used, they are called polyester fiberglass, epoxy fiberglass, and phenolic fiberglass. The essential oil bottle made of glass is light, hard, non-conductive, stable in performance, high in mechanical strength, less in recycling and corrosion-resistant.
Why is the veterinary medicine bottle deformed?
Nowadays, more and more people keep pets, and their health is more and more concerned. Seeing their little ones suffer, the owner is very distressed, so the market for veterinary drugs is also getting bigger and bigger, and many sellers are buying things. At the same time, it is found that the veterinary medicine bottles are deformed. What are the reasons for them to deform? Most of the deformation of veterinary medicine bottles occurs when the veterinary medicine bottle manufacturers pack some special medicines. In the hottest season of veterinary medicines, some special veterinary medicines are poured, which often occurs when the temperature is much higher than the ambient temperature. After the general veterinary drug is placed in the bottle, close the cap immediately. In order to avoid splashing or knocking over the bottle with canned veterinary medicine, usually the volume of the bottle is slightly larger than the volume of liquid that needs to be injected, and the air temperature left in the bottle after thermal charging is the same as that of veterinary medicine. For a period of time, the veterinary medicine and the air inside drop to a temperature similar to the outside environment, the cause of thermal expansion and contraction and liquefaction can cause some negative pressure inside the bottle. If the negative pressure exceeds the strength of the bottle wall, the plastic bottle wall may sag and deform. The deformation of veterinary medicine bottles originates from the principle of compatibility of chemical substances. When the polarity of the material of the plastic packaging bottle is similar to the polarity of the organic solvent of the pesticide it packs, mutual solubility will occur. Over time, it will develop into infiltration. Since the bottle is now airtight, there is less organic solvent seeping out of the molecular spacing of the bottle's material, creating a negative pressure that will eventually deform the bottle. The composition of the veterinary medicine bottle is very complex, which contains impurities of specific special solvents or raw materials, which oxidize with the air remaining in the bottle, and deform the bottle due to the negative pressure caused by oxidation. Veterinary medicine bottles are generally made of high-density polyethylene, which may occur when veterinary medicine bottles containing this ingredient are used to package esters or ketones, and aromatic solvents. Oxidation creates negative pressure, which can deform the veterinary medicine bottle.
How is the quality of the brown bottle guaranteed?
Many people ask why brown bottles are used in most bottles these days. The first reason is that light can damage the reagents. It is high-energy light, mainly in the near-ultraviolet region, that degrades the reagents. High-energy light can be blocked by brown bottles. Considering factors such as cost and convenience, reagents in brown bottles are used. How to ensure the quality of the brown bottle during the production process? Let us explain it to you below! First, the appearance quality of the brown bottle is divided into material color, smoothness and transparency; the first factor is the color of the brown bottle, which can be divided into three grades according to regional standards: refined white material, advanced white material and ordinary white material. The same color depends on the smoothness and transparency of the brown bottle. The appearance of a good bottle should be free of impurities, bubbles, cold spots, sticky bottles, wrinkled skin, putty, etc. Another thing to pay attention to is the "double stitching of the bottle". Some brown bottle manufacturers are not strict with quality requirements, and there are often large stitching and double stitching; finally, looking directly at the bottle body, the large brown The transparency and permeability of the bottle are better, and the small glass bottle will not have particularly obvious halo wavy lines. Secondly, the internal quality of the brown bottle: there are many subdivisions, such as the strength of the brown bottle, the temperature difference between quenching and heating, the verticality of the bottle body, the thickness of the bottle body, no deformation, crooked neck, the flatness and roundness of the bottle mouth There is no cold granule frying mouth, no broken silk in the whole grain, no diameter tumor on the bottle mouth, etc. The most common problems of Qingdao brown glass bottle manufacturers are: the crooked neck of the small-mouth bottle, the shaking of the small-mouth flat bottle, and the expansion of the large-mouth bottle. The consequence of the crooked neck of the vial is to affect the appearance, and it cannot be filled or sealed by the machine; the reasons are the mold factor, the high speed of the production machine, and the mismatch of the bottle clamps. The shaking of the small flat bottle is mostly caused by the failure of the anti-skid line at the bottom of the mold, the deviation of the bulkhead and the excessive speed of the machine; the result of the expansion of the wire in the large bottle is that the wire becomes thicker and cannot be sealed, which is caused by the large mold or the machine speed. Caused by poor heat dissipation or shallow pump head.
The difference between veterinary medicine bottles and ordinary plastic bottles
In the past, the development of the veterinary drug market was chaotic, and all kinds of counterfeit and inferior products were rampant. For veterinary drug bottle packaging, the market only focuses on the positioning of packaging containers at the point of demand. Therefore, for a long time, the packaging design of veterinary medicine bottles is simple and the quality is generally not high, and many non-professional veterinary medicine bottle manufacturers are also engaged in the production of veterinary medicine bottles. Now, with the standardization of the market, some small and medium-sized factories are being phased out gradually, and the requirements for veterinary medicine bottle packaging are getting higher and higher. At the same time, manufacturers of veterinary medicine bottle packaging will also become more specialized, and those with a deeper understanding of the market will become more and more popular. Features of veterinary medicine bottle of Qingdao Laobo Glass Products Co., Ltd.: It is an ideal thermal insulation material, with less smoke, good impact resistance, creep resistance at room temperature, good processability, can be used continuously at 240~270℃, good Radiation resistance, selection and application of various veterinary drugs in different dosage forms, properties and grades into veterinary drug plastic bottles. For general powder injections, oral preparations and high-dose infusions, the use of low borosilicate glass or neutralized soda lime glass can still meet its chemical stability requirements. The composite material is made of polyethersulfone as matrix resin and carbon fiber, which has high strength and hardness at 200 °C, and can still maintain good impact resistance at 100 °C. The difference between veterinary medicine bottles and ordinary plastic bottles is roughly as follows: 1. The medicine has no moisture and no deterioration during the use period, and has good sealing and barrier properties, which can prevent the influence of light, heat, steam, oxygen, etc. on the medicine. 2. The inner wall of the bottle is in direct contact with the drug, and the bottle-making material meets the requirements of drug packaging and the safety of the drug. 3. The shape, size and structure of veterinary medicine bottles should meet the requirements of various filling machines of pharmaceutical companies and the requirements of high-speed automatic filling machines.
Why do Qingdao oral liquid bottle manufacturers not use neutral borosilicate glass?
We all know that the oral liquid glass bottle is a packaging container for oral liquid, and it is one of the important packaging containers in the pharmaceutical industry. Oral liquid is particularly afraid of corrosion, and the ultraviolet rays of the sun affect the quality of the product. Therefore, not only for the physical and mental health of consumers, but also for the popularity of Qingdao oral liquid bottle manufacturers, the design of the light-proof performance of oral liquid glass bottles must be good to prevent the occurrence of The product has already deteriorated before the expiration date. The bottle mouth design requirements for oral liquid glass bottles are narrow-mouthed bottles, and the sealing must be good to prevent leakage, such as some rare areas: the packaging in the oral liquid glass bottles purchased by customers The product is only half a bottle, which has caused dissatisfaction among consumers. The price of oral liquid has always been low. If the product fails to meet customer satisfaction, then the oral liquid glass bottle manufacturer will lose trust and face bankruptcy. danger. Only by improving the performance of the brown bottle itself to adapt to the development. The material of the oral liquid glass bottle is medicinal soda lime glass and low borosilicate glass. However, my country is following the pace of foreign countries, and many medicinal glass bottles have been changed to neutral borosilicate glass bottles. The neutral borosilicate glass bottles contain 8%-12% diboron trioxide, and the number of thermal boron expansion lines is low, which can guarantee The glass bottle made of neutral borosilicate glass contains strong acid and strong alkali, and it will not peel off, not turbid, and not deteriorate. But why didn't the material made by Qingdao oral liquid bottle manufacturers change to neutral borosilicate glass? There are two main reasons: First, low borosilicate glass and chemically treated soda-lime glass can meet the chemical stability requirements of both medicines and oral liquids. The degree of corrosion of medicines to glass materials is generally that the liquid is greater than the solid, and the alkalinity is greater than the acidity, especially the strong alkaline water injection has higher requirements on the chemical properties of medicinal glass bottles. The second is that my country's economy is developing. Neutral borosilicate glass bottles are expensive, and the price of oral liquid in a good package will be several times higher than that of oral liquid in ordinary materials, so market conditions do not allow it.
