PP film washing lines are available in different types here which one can opt for based on the volumes that need to be processed and the type of contaminants that need to be removed.
This is the most basic type of washing line where the washing and the extrusion are done in one single equipment. This is good for less contaminated films and smaller productions.
In this type of washing line, the washing and extrusion are done in one single equipment with a double-screw extruder which provides more efficient melting and better plasticizing. This type of washing line is ideal for heavily contaminated films due to the washing and extrusion being more vigorous and thus removing more contaminants.
These are smaller units that combine washing with separation technologies such as float-sink tanks or air classifiers. These are usually used for very small operations that process a particular waste film.
This type of machine is used to wash a batch of film at a time usually containing tanks of chemicals and water that are used to wash the film. This is good for small batches or films that are difficult to wash.
This type of washer moves film through it continuously using chemicals and water to wash the film. This is better for larger operations where a lot of film is processed.
This type of washing line uses a combination of centrifugal force and the density of different materials to separate contaminants from plastic films. This is effective at removing smaller particles like sand or dirt.
The materials used in a PP film washing line construction play a major role in the durability, largely because Polypropylene film washing lines process abrasive materials, exposure to chemicals, water, and varying temperatures.
A majority of the washers utilize this element due to its robust properties. Stainless steel makes resistant parts made out of this material to rust, corrosion, and the harsh environment present in the washers.The above feature not only increases durability but also has the capacity to increase the life of the users' equipment.
Some internal components like screws and mixing tanks are lined with rubber. Rubber-lined components serve to absorb a part of the abrasion that comes from the plastic film. The rubber also acts as a buffer to exploitation which may wear down machinery earlier than expected if nothing is done.
Some vessels may have special coatings like ceramic or chrome plating on high-wear areas. These coatings are made with elements that increase their hardness, and as a result, they are less likely to be damaged by abrasive plastic film. In addition, the coatings also extend the life of the equipment in washers by providing a smoother surface, which reduces friction and is thus beneficial.
As much as the materials may be the same, motors and gearboxes in heavy-duty applications are built from sturdier materials. In these cases, manufacturers use metals like cast iron and alloy steel that are tough enough to withstand torque and load.
As much as stainless steel is common, certain types of washers may require additional chemical-resistant materials. These include plastic parts made from materials like polyethylene or polypropylene.Given that these films are exposed to a lot of chemicals during washing, these materials do not weaken or break down easily.
This equipment is used to clean plastic films and make them ready for reuse. There are a variety of options available on the market today for buyers who intend to buy the washing lines. The following factors should be considered when purchasing these washing lines.
The type of plastic film that needs to be washed determines the kind of washing line that needs to be purchased. PP washing lines are suitable for Polypropylene films only. Any washing line that has been built for HDPE or LDPE films has to be constructed to handle the specific demands of these materials, such as different washing requirements and machine wear.
The polypropylene films in question are usually contaminated with different types of pollutants such as labels, glue, dust, and other types of plastic. High levels of contamination require robust washing lines such as those known to have features, including advanced separation technologies, chemical washes, mechanical agitation, etc.
This refers to the amount of film that can be processed in a given period, typically an hour or a day. Polypropylene washing lines vary greatly in the volume that they can handle and this can go from small batch washes that may be able to process one hundred kilograms of film in an hour to large-scale continuous washing lines that process several tonnes in an hour.Just like that, larger operations need larger-capacity washing lines in order to keep up with the high demand.
Some washing lines require more energy than others to run and this is an important consideration when selecting a washing line. There are various ways to make washing lines energy efficient, such as using advanced motor technologies, heat recovery systems, and more efficient washing and drying methods.The energy requirements of the washing lines also need to be considered in order to avoid high utility bills and become less sustainable.
Different types of washing lines vary in prices depending on the type of washing line, the materials used to construct it, the technologies it employs, and the capacity it has. Therefore, it is important to consider a buyer's budget before purchasing a washing line that is required to meet production needs.
These washing lines are used in many industries in the recent past to deal with the problem of plastic waste. The following are some common scenarios when using a PP film washing line.
Recycling plants use washing lines to clean post-consumer plastic films such as bags and wraps before they are processed into recycled pellets. Without washing these films, they cannot recycle them as the contaminants present will affect the quality of the recycled material that is required.
Packaging industries handle a large amount of plastic film waste during their normal operations. They use washing lines to clean this waste film so that they can reuse it in their own packaging or sell it to recyclers who make it into new materials.
PVC films may be contaminated with dust, residues, or adhesives from manufacturing processes. Washing lines are used to clear this film waste so it can be recycled and reused in the manufacturing process.
In agriculture, plastic films are used for mulching, greenhouse covering, and silage wrapping. PP washing lines are used to clean the films as they are required to remove soil, organic matter, and other debris before recycling or disposal.
Construction debris may contain loads of plastic sheeting used as vapor barriers or debris fabric. Washing lines help in cleaning this wash so as to reuse it or incorporate it back into the manufacturing process.
The companies that produce agricultural film for mulching and other uses use washing lines to keep the film construction waste clean so that it does not enter landfills. They have to wash off any soil or other agricultural remnants on the film so that it does not contaminate the new material.
Proper maintenance and repair of PP washing lines help to increase the longevity and efficiency of the lines. People need to understand some basic maintenance practices and how to address repairs when needed and this should not be very difficult.
This maintenance goes hand in hand with the production schedule so as to not interfere with the production process. Operators should conduct daily and weekly checks on critical components such as filters, screens, and pumps to identify any potential issues that may arise. In addition, they should also check for any initial signs of wear or damage on the components such as mechanical parts or drive motors, as well as lubricate moving parts, and there is a need for preventive maintenance on mechanical components.
PP washing lines consist of many moving parts, and these parts require frequent lubrication so that they do not wear out easily. Lubrication should be done on components like bearings, gearboxes, and motors because friction is generated which wears out the machine. It is worth noting that lubrication should be done with the manufacturers' recommended lubricants and should also be done according to the maintenance schedule.
It is critical to always look at and replace wear items such as blades, screens, and baskets. The effect of having worn-out parts is that washing efficiency decreases and contaminants begin to reside in the washed film.A worn-out screener could mean that more contaminants are getting into the washed film due to less efficiency in washing. Following the manufacturer's guidelines on when to replace these parts is very important.
Some of the most common repairs that may need to be conducted on PP washing lines include repairing or replacing damaged parts, electrical repairs, and motor servicing. All these repairs are mainly professional repairs, but some repairs can easily be carried out by the operator.
