Overview of PVA Sponge Roller Technology<\/h2>\n

A PVA sponge roller<\/b> (often simply called a PVA Roller\/nodular brush\/PVA absorbent roller) is a highly porous, open-cell synthetic sponge. Its most defining characteristic is its affinity for water; unlike a standard sponge roller<\/b><\/a> that might repel liquid initially, a PVA roller can absorb several times its own weight in water almost instantaneously.<\/p>\n

PVA Sponge Roller<\/a> are made of Polyvinly alcohol(PVA) material ,Porous elastomers obtained by crosslinking specific water-soluble resins have strong water absorption capacity due to the hydrophilic bonds in their molecular structure. The general water absorption rate is 8-10 times its own weight, which is the water absorption effect, the lowest price and the largest use of products.

\nIt’s a roller shape warpped on a PVC pipe, the surface is smooth in hard condition while soaking water it becames soft. Due to excellent water absorbing feature it’s widely used on PVA sponge roller for PCB wet process, glass washing industrial and other field.<\/span><\/p>\n

pva sponge Key Feature<\/h2>\n
\n
    \n
  • pva sponges absorbing roller is a type of roller with multiple micropores and interconnected micropores, which has good water absorption and corrosion resistance. It is ideal to use it to absorb surface moisture.<\/li>\n
  • It requires a moist state, so it is stored in a water tank.<\/li>\n
  • The sponge water absorbing roller made of hydrophilic polymer PVA (polyvinyl alcohol) has good water absorption and retention ability due to the micro connected pores of the hydrophilic substrate.<\/li>\n
  • In addition, its unique softness can be widely used in the cleaning, pressing, water absorption, and dehydration processes of printed circuit boards, LEDs, glass products, steel plates, aluminum plates, and other panels.<\/li>\n<\/ul>\n<\/div>\n

    Technical specifications of sponge suction roller:
    \n\u2460 The water absorption capacity can reach 6-10 times its own dry weight.
    \n\u2461 The general usage temperature should not exceed 60 \u2103, otherwise it will age and shorten the service life. If the water absorbing roller is not used for a while, it should be cured in clean water.
    \n\u2462 The normal usage period is 5-8 months
    \nRemark:<\/p>\n

    1. The operating temperature should not exceed 60 \u2103, otherwise it will age and shorten the service life.
    \n2. Acid and alkali resistance.
    \n3. When not in use, maintain in clean water to prevent deformation.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
