Chemical Container Type: Selection and Specification of Different Products

Chemical Industry Chemical Container Types: Selection and Application Guide

In the chemical industry, the selection and application of chemical containers is crucial. A suitable container can not only ensure the storage safety of chemical substances, but also meet the needs of production, storage and transportation. This article provides a detailed analysis of the types, selection criteria and specifications of different chemical containers to help those involved in the chemical industry make informed decisions.

1. chemical container type and scope

1. plastic container

• Scope: Plastic containers because of its corrosion resistance, lightweight and plasticity and widely used in chemical products storage.
• Common types :PP (polypropylene), PE (polyethylene), LDPE (low density polyethylene), PPR (food grade polypropylene), eva (polyethylene ethylene copolymer), etc.
• Features: Plastic containers are usually reusable and suitable for frequent replacement scenarios, but they are easily affected by temperature and humidity, and need to pay attention to sealing.

1. glass container

• Scope: Glass containers are often used to store non-toxic, non-corrosive liquids, such as general reagents, solvents, etc.
• Common types: glass bottles, glass jars, glass test tubes, etc.
• Advantages: glass container transparent, easy to observe, suitable for laboratory use, and non-toxic, safety factor is high.
• Disadvantages: The glass container is fragile, the cost is high, and it is not suitable for mass storage or transportation.

1. metal container

• Scope: Metal containers are suitable for strong corrosion, high temperature or extreme environment storage, such as acid and alkali reagents, high temperature reactants, etc.
Common types of
• : stainless steel, aluminum, titanium, etc. Metal Container Selection and Application
• Advantages: corrosion resistance, high temperature use, suitable for special environment storage.
• Precautions: Metal containers need to be regularly inspected to avoid corrosion or leakage, and select appropriate capacity specifications.

1. composite container

• Scope: Composite containers combine the advantages of multiple materials and are usually used for special needs storage.
• Common types: metal plastic composite, glass plastic composite, etc.
• Advantages: combined with metal strength and plastic corrosion resistance, suitable for complex environment storage.
• Disadvantages: The cost is higher and may not be as economical as a single material container.

Specification Requirements for Chemical Containers

1. Container Capacity

• Capacity according to the storage material quantity and use frequency, too high capacity waste, too low capacity is not economical.
• Select the need to consider the liquid density, temperature changes on the volume of the impact.

1. Container Weight

• Lightweight containers help transport and storage, but in the choice of the need to ensure that the strength is sufficient to avoid weight caused by container damage.

1. Security

• Containers must comply with relevant safety standards, such as ISO certification, RoHS standards, etc.
• Consider the storage of material toxicity and reaction characteristics, select leakproof, shockproof performance of the container.

1. Tightness

• High sealing container can prevent liquid evaporation or leakage, the choice should be based on the storage material properties and storage environment.
• Common sealing methods include screw cap, screwed design, airtight design, etc.

Storage Conditions and Selection Recommendations

1. Storage Environment

• For flammable, explosive, toxic substances, need to choose explosion-proof, anti-toxic performance of the container.
• Store in dry, ventilated, away from fire and strong acid and alkali area.

1. Storage temperature

• Different substances on the storage temperature has different requirements, select the container to consider the temperature range.
• For example, acidic liquids need to be stored at room temperature, while high-temperature liquids need to be stored in high-temperature certified containers.

1. Storage humidity

• Some substances are easy to absorb water or deliquescence, choose moisture-proof containers to avoid losses.
• Common moisture protection measures include sealing design and internal gaskets.

1. Environmental Protection and Sustainability

• As environmental awareness increases, the choice of degradable and recyclable environmentally friendly containers is particularly important.
• Different environmental standards for container materials and treatment methods have different requirements.

Conclusion

The selection and application of chemical containers requires a comprehensive consideration of the nature of the stored material, the storage environment, the frequency of use, and cost-effectiveness. Containers made of different materials, such as plastic, glass and metal, have their own advantages and disadvantages and are suitable for different storage scenarios. Choosing the right container type can not only ensure the safety of storage, but also improve production efficiency and environmental performance. The chemical industry in the procurement and use of chemical containers, should be combined with the actual needs, follow the relevant regulations and standards, to make the most appropriate decision.
