What are the Factors to Consider While Choosing a PVA Sponge Roller?

PVA sponge roller has been widely used in the cleaning industry.  Because of it soft nature, PVA roller could be used to scrub the cleaned substance without harming the surface.  The porous characteristic also enhances detergent to flow through and acted as cleaning strategy.

In this article, we are going to review some factors for engineer to consider while choosing PVA sponge roller for your dedicate cleaning process.

1.      Physical dimension accuracy

PVA sponge should come in a dedicate design pattern in order to suit for certain cleaning tools.  PVA sponge supplier should be able to manufacturer the product complies with spec but also a narrow tolerance variation.

In many practical cases, we do see some defects that cause by big

variation of PVA sponge.  Due to the big variation, field engineer need to spend additional work in order to fine tuning the cleaning machine to optimize the cleaning result, this has lead an additional work for field engineer and also one of the importance factors that lead to unstable cleaning result.

2.      Pore Size of PVA Sponge

Remember to check with the PVA roller pore size while choosing any PVA roller for your clea

ning process.  Pore size acts as a

130um pore size

130um pore size

waterway for detergent to flow during the cleaning process, larger pore size will allow more water flow through the cleaning substance surface.

3.      Uniformity of porosity

In high tech industry, cleaning effect is one of the importance factors affecting overall product yield.  Field engineer has been putting a lot afford in cleaning process but the uniformity of porosity in PVA roller is always be overlooked.

Porosity size acts as waterway through out the cleaning process.  Many PVA roller claimed with certain PVA pore size unfortunately the manufacturer fail to maintain the uniformity of pore size.  This cause the cleaning detergent may not evenly spread out during the cleaning process and may cause some area with insufficient cleaning.

4.      Sponge hardness

Cleaning process is a unique process for individual cleaning tools and defects.  Field engineer may swap the cleaning strategy from time to time due to the contaminant on clean substance.

Harder sponge may suitable for certain contaminant while others process may prefer a softer sponge.

5.      Durable

Durability is not an issue unless cleaning field engineer wants to frequently change the deformed PVA roller.  PVA roller is always working under difference detergent and pre-load pressure; this may affect the PVA roller life-span significantly.  Not durable PVA roller will cause significant in cleaning effect.

Many engineers establish a periodic PVA Roller changing frequency; and a more durable PVA roller may last longer then the other.

6.      Material Leach Out

Leach out count could be measured under LPC meter (Liquid Particle Counter). One of the reasons for certain PVA roller has poorer durability because of PVA material leach out during the cleaning process.  Apart from there, leach out may also cause micron size particle left over on the clean substance surface that bring forward to subsequence process.

Clean substance with highest cleaning requirement may require a stringent leach out needs.

7.      Technology Support

Cleaning process is not identical process and need to perform continual improvement due to latest contaminant requirements.  Difference design of cleaning tools and application are the fundamental for improvement activity.

Select a PVA sponge manufacturer with experience field knowledge and commitment to new technology is a must for next regime improvement.

After you have considered above 7 factors, I guess filed engineer has better sense to select an appropriate PVA sponge roller that best suit your cleaning process.
