海绵吸水辊是种多微孔，而且微孔之间相互连通，吸水性良好，具有较好的耐腐蚀性能。用它来吸除表面水份是十分理想的，它本身要求滋润状态，故将其放在水槽中保存。由亲水性高分子PVA(聚烯醇)制成海绵吸水辊，因亲水性基材的细微连结气孔使之拥有良好的吸水、保水能力，再加上其独到的柔软性，可以广泛使用于印制板、玻璃制品、钢板、铝板等其它面板的清洗、压液、吸水、脱水工序中。
海绵吸水辊的技术指标：
1、吸水能力可达自身干重的6~10倍；
2、一般使用温度不可超过60℃,否则会老化和缩短使用期限,粘结好的吸水辊,如一时不用,应养护在清水中；
工业吸水海绵辊又称吸水辘、吸水辊。常用的品种按材料分有以下几类：
PVA吸水海绵：以特定水溶性树脂采用交联反应而得到的多孔性弹性体，因分子结构中具有亲水键而具备强烈的吸水能力。一般吸水率为自身重量的8-10倍，是吸水效果最好，价格最低，使用量最大的产品。
PU吸水海绵:以聚氨脂类树脂为基通过特殊工艺形成多孔连续的发泡体具有耐化学介质性好温度稳定性好等特点广泛应用于OSP段落的切液等工序但价格高昂吸水率有限.
PVC吸水海绵:以聚氯乙烯为基在特定工艺条件下形成的发泡体耐化学介质性优良一般用于强腐蚀段落的切液但价格高昂使用受到一定限制.
PP吸水海绵:以聚丙烯树脂为基在特定工艺条件下形成的弹性体耐温度、耐腐蚀性能优良，只用做切液、挡水滚轮。 采用进口PVA材料以特定水溶性树脂采用交联反应而得到的多孔性弹性体，因分子结构中具有亲水键而具备强烈的吸水能力。一般吸水率为自身重量的8-10倍，是吸水效果最好，价格最低，使用量最大的产品;专门开发了大型玻璃洗片机器用吸水海绵替代了进口产品;可直接实现节能降耗提高生产效率的目的。兴宏发(义乌)橡塑制品有限公司Sponge roller is a kind of many pores, and interconnection between the pores, good water imbibition, and has good corrosion resistance. Use it to remove surface moisture absorption is very ideal, it itself requires moist state, therefore, put it in the sink. Made of hydrophilic polymer PVA (poly enol) sponge roller, due to the hydrophilic substrate subtle link porosity make it has good water absorption and water retention ability, coupled with its unique flexibility, can be widely used in printed circuit board, glass, steel plate, aluminum plate, and other panel cleaning, liquid pressure, water absorption and dehydration process.
Sponge roller technical indicators:
1, the water absorption ability of 6 ~ 10 times their dry weight;
2, general use shall not exceed 60℃temperature, otherwise it will aging and shorten the service life, felt good suction roll, such as a need not, should be maintained in clean water;
Industrial absorbent sponge roller, also known as water roll and water roller. Common varieties according to the material has the following categories:
PVA absorbent sponge: in a specific water soluble resin obtained by crosslinking reaction of porous elastomers, due to the molecular structure of hydrophilic key has strong water absorption ability. General water absorption for 8 to 10 times their own weight, suction effect is best, lowest price, usage is the biggest product.
PU absorbent sponge, with polyurethane resin as the base by a special process to form porous continuous foaming body has a good temperature stability, good resistance to chemical media is widely used in OSP paragraph cutting fluid, but the price of high water absorption is limited.
PVC suction sponge: polyvinyl chloride (PVC) as a foaming body formed in the specific process conditions good resistance to chemical media commonly used in strong corrosive paragraph cutting fluid but expensive to use.
PP absorbent sponge: polypropylene resin as the base formed in the specific process conditions of elastomer excellent temperature resistance, corrosion resistance, cutting fluid, water retaining only do roller. Imported PVA materials in a specific water soluble resin obtained by crosslinking reaction of porous elastomers, due to the molecular structure of hydrophilic key has strong water absorption ability. General water absorption for 8 to 10 times their own weight, suction effect is best, lowest price, usage is the biggest product; Specially developed large glass washing machine use absorbent sponge instead of the imported products; To achieve the purpose of saving energy and improving the production efficiency directly.
