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 porous and interconnected between microporous, absorbent, and have good corrosion resistance. Use it to suck the water surface is ideal, which itself requires moist state, so put it in the sink to save. By the hydrophilic polymer PVA (poly alcohol) made sponge roller, because the subtle links hydrophilic substrate pores so that it has a good absorbent, water retention capacity, coupled with its unique softness, can be widely used the printed circuit board, glass, steel, aluminum and other panels cleaning, pressure liquid, water, dehydration step.
Sponge rollers technical indicators:
1, the absorbent capacity of its dry weight of 6 to 10 times;
2, the general temperature should not exceed 60 ℃, otherwise it will shorten the lifespan of aging and, good suction roll bonding, such as the moment not be curing in water;
Industrial absorbent sponge roller, also known as water reel, suction roll. Common varieties of material pided by the following categories:
PVA absorbent sponge: the specific water-soluble resin obtained by crosslinking reaction using the porous elastic body, because the molecular structure having a hydrophilic bond with a strong absorption capacity. Water absorption is generally 8-10 times its own weight, is water the best, lowest price, with the largest amount of product.
PU absorbent sponge: a polyurethane resin as the base through a special process to form a continuous porous foams have good chemical resistance and good temperature stability characteristics are widely used in the cutting fluid passages OSP processes but expensive limited absorption .
PVC absorbent sponge: the polyvinyl chloride-based process conditions in a particular form of foam with excellent chemical resistance is generally used for highly corrosive liquid passages cut subject to certain restrictions, but expensive to use.
Absorbent sponge PP: polypropylene resin as base formed under specific conditions of temperature-resistant elastomer, excellent corrosion resistance, only the cutting fluid used, retaining roller. Imported PVA material used in a specific water-soluble resin obtained by the crosslinking reaction of the elastic porous body, because the molecular structure having a hydrophilic bond with a strong absorption capacity. Water absorption is generally 8-10 times its own weight, is water the best, lowest price, the largest use of products; specially developed large glass washing machine with an absorbent sponge replace the imported products; increased energy consumption can be directly implemented production efficiency.
