PVA Sponge Roller Pore Size
PVA Sponge looks similar from outer appearance; however there are several fundamental parameters from sponge design, among all, pore size is one of the fundamental parameters.
Difference cleaning mechanism and defect categories may require difference porous structure design.
We review 7 importance factors while selecting a suitable PVA roller.
Pore structure acts as a waterway for detergent to flow during the cleaning process, larger pore size will allow more water flow through the cleaning substance surface.
Small contaminant in clean substance surface is removed by the PVA sponge by a direct contact between brush and clean substance, the pore structure on sponge surface engulf the contaminant on the clean substance. The sub-sequence rotational effect on sponge roller and detergent fluid will dislodges the contaminant from clean substance surface and flush away from the clean substance surface.
If we are unable getting better cleaning result, please consider the pore size selection in order to get the best performance.
PVA Porous Design
The porous design for PVA sponge roller is Open Pore design. This means all the pore is interconnecting with each other. Compare to close pore design, open pore enhance water flowing through during the cleaning process.
Purpose of PVA Sponge Roller Pore
It is a open pore structure for PVA sponge roller. The open pore structure inter-connected every pore which favour to water flow. An uniform pore structure will further enhance the solution flow during the cleaning process.
PVA Sponge Roller Pore Foaming Mechanism
Starch method is the most commonly used method for generating porous structure in PVA sponge roller, however they do have non-startch method for dedicated pore size.
Generally speaking, pore size generating under starch method is always bigger than non-starch process.
