Further information on chemical hoses
Here you will find comprehensive answers to frequently asked questions about the use of chemical hoses in electronics, which are crucial for the safe and efficient handling of chemical substances in electronic applications. Chemical hoses in electrical engineering are specially designed hoses that are used for the safe transportation and distribution of chemical substances within electronic systems and devices.
What are the most important properties of chemical hoses and how do they differ from other types of hoses?
The most important properties of chemical hoses are:
1. resistance to chemicals: chemical hoses are specially designed to offer high resistance to a wide range of chemicals. They are able to withstand contact with aggressive liquids and gases without damaging the hose.
2. temperature resistance: Chemical hoses must be able to withstand both extreme cold and heat. They should be able to withstand both low and high temperatures without compromising their structural integrity.
3. flexibility: Chemical hoses must be flexible to adapt to different environments and applications. They should be able to tolerate bending and deformation without cracking or leaking.
4. pressure and vacuum resistance: chemical hoses must be able to withstand high pressure and vacuum conditions without bursting or collapsing.
5. durability: Chemical hoses should have a long service life and function reliably even under demanding conditions. They should be resistant to wear, abrasion and weathering.
Compared to other types of hoses, such as water hoses or air hoses, chemical hoses differ mainly in their resistance to chemicals and their temperature resistance. They have been specially developed for use in chemical plants, laboratories or industrial environments where contact with aggressive chemicals and high temperatures can occur frequently.

What types of chemicals can be safely transported in chemical hoses and which should be avoided?
There are various types of chemicals that can be safely transported in chemical hoses. Here are some examples:
- Water-based solutions: Chemical hoses are usually suitable for transporting water and water-based solutions such as acids, alkalis and salt solutions.
- Organic solvents: Many chemical hoses can also safely transport organic solvents such as ethanol, methanol, acetone and other alcohols.
- Oils and fats: Chemical-resistant hoses can also be used to transport various oils and fats.
- Food and beverages: Chemical hoses that are approved for the transportation of food can be safely used to transport beverages, dairy products, oils and other foods.
However, there are also chemicals that should be avoided as they can compromise the integrity of the chemical hose or pose safety risks. These include:
- Strong acids and alkalis: Some chemical hoses may not be resistant to strong acids (e.g. sulphuric acid) or alkalis (e.g. sodium hydroxide). In such cases, special hoses suitable for these chemicals should be used.
- Halogenated solvents: Chemical hoses may also not be resistant to halogenated solvents such as chloroform, dichloromethane and carbon tetrachloride. It is important to check the compatibility of the hose with these chemicals before transportation.
- Volatile chemicals: Chemical hoses should not be used for the transportation of extremely volatile chemicals such as ether or highly flammable solvents as they can pose safety risks.
It is important to check the chemical manufacturer's specifications and safety data sheets, as well as the specific properties and recommendations of the chemical hose manufacturer, to ensure that the correct hoses are selected for the safe transportation of the chemicals in question.

How are chemical hoses manufactured and what materials are used?
Chemical hoses are usually manufactured by extrusion. In this process, a thermoplastic polymer is pressed through a die and formed into the desired hose shape. The hose is then cooled and cut.
The materials used depend on the requirements of the chemical hose. Plastics such as polyvinyl chloride (PVC), polyethylene (PE) or polypropylene (PP) are often used for transporting chemical substances. These plastics are resistant to chemicals and offer good barrier properties against gases and liquids.
For more demanding applications where greater chemical resistance is required, special polymers such as fluorocarbons (e.g. PTFE) or fluoroelastomers (e.g. FKM) can also be used. These materials are characterized by their high resistance to aggressive chemicals.
In addition, chemical hoses can be equipped with various reinforcement layers to ensure improved pressure and temperature resistance. These layers can consist of woven fabrics, wire mesh or plastic tapes.
It is important to consider the specific requirements of the application when selecting the chemical hose to ensure that the hose has the desired chemical resistance and mechanical strength.

What is the typical service life of a chemical hose and what factors can influence its durability?
The typical service life of a chemical hose depends on various factors and can therefore vary. As a rule, however, a high-quality chemical hose can last for several years.
Some factors that can influence the durability of a chemical hose are
1. chemical resistance: chemical hoses are usually designed for use with certain chemicals. If a chemical hose comes into contact with a chemical for which it is not resistant, this can lead to material fatigue and a shortened service life.
2. temperature: High temperatures can affect the durability of a chemical hose. Most chemical hoses have a certain temperature resistance that should not be exceeded in order to avoid damage.
3. pressure: Excessive pressure can lead to overstretching or bursting of the chemical hose, which shortens its service life.
4. mechanical stress: improper handling, such as excessive bending or twisting of the hose, can lead to material fatigue and affect its durability.
5. UV radiation: Chemical hoses used outdoors can be damaged by UV radiation, which can lead to cracks and material fatigue.
It is important to follow the manufacturer's specific instructions to maximize the life of the chemical hose. Regular inspections and maintenance can also help to detect damage at an early stage and extend the service life.

What safety precautions should be taken when handling chemical hoses to avoid accidents or leaks?
When handling chemical hoses, the following safety precautions should be observed to avoid accidents or leaks:
1. selecting the correct hose material: ensure that the hose material used is suitable for the type of chemicals it will come into contact with. Check the chemical resistance of the hose according to the manufacturer's instructions.
2. hose inspection: Check the hose for damage, cracks, wear or other defects before each use. Do not use the hose if it is damaged.
3. proper storage: Store the hoses in a dry and well-ventilated place, away from direct sunlight and heat sources. Keep the hoses away from sharp objects or chemicals that can damage the hose.
4. correct installation: Ensure that the hose is properly installed and correctly connected to the corresponding fittings. Ensure that the fittings are tightly screwed to prevent leaks.
5. safety valves and overpressure safety devices: If necessary, install safety valves and overpressure safety devices to prevent excessive pressure in the hose system.
6. protective equipment: When handling chemicals and chemical hoses, wear suitable personal protective equipment, such as gloves, goggles and protective clothing, to protect against possible splashes or leaks.
7. education and training: Ensure that people working with chemical hoses are informed and trained on the correct procedures and safety measures.
