?吸水海绵、?PVA吸水海绵片材PVA强力吸水海绵是以聚乙烯醇为原料的连续气孔之多孔质体。气孔径气孔率控制自由。随使用目的而定，着色以及形状的加工上可任意.选择品种。且耐磨性优良。无论产业用途、一般生活均有着广泛的领域:医疗棉，电子清洁棉。PVA海绵之无以类比的特长：连续气孔，容积的约90%由气孔形成.PVA海绵，乍看上去，好似固态块状，但如果用微眼去看，其容积的90%都是中空穴（气孔）的基质部呈立体网状构造。每个气，孔完全连续而成。这种一体构造是PVA海绵的特点，具有诸多功能。亲水性令人惊叹的吸水、保水能力。与一般氨甲脂海绵不通，有极高的亲水性与纵横交错的微细孔产生毛细管现象，发挥着超群的吸水、保水性能。一接触水分，则高速吸附，保存在绵体内部。（柔软性）柔软接触不会划伤，湿润状态柔软性、弹性好，特别是作为洗净材料及擦拭材料时不会伤及对象物表面。?Absorbent?sponge,?PVA?absorbent?sponge?sheetPVA?is?a?strong?absorbent?sponge?PVA?as?continuous?pores?of?a?porous?material?body.?Porosity?and?pore?diameter?control?freedom.?With?the?purpose?of?use,?depending?on?the?coloring?and?processing?of?arbitrary?shape.?Select?varieties.?And?excellent?wear?resistance.?Whether?industrial?use,?general?living?both?have?a?wide?range?of?areas:?medical?cotton,?electronic?cleaning?cotton.?PVA?sponge?no?analogy?strengths:?continuous?pore?volume?of?about?90%?by?forming?pores?.PVA?sponge,?at?first?glance,?like?a?solid?block,?but?if?you?look?at?micro?eye,?which?is?90%?of?the?volume?of?the?hole?(pores)?in?a?three-dimensional?network?structure?matrix?section.?Each?air?hole?is?made?completely?continuous.?This?one?is?the?most?important?feature?of?PVA?sponge?structure,?with?many?features.?Stunning?hydrophilic?absorbent,?water-holding?capacity.?General?methotrexate?fat?sponge?barrier,?there?is?a?high?hydrophilic?and?micropores?criss?capillary?action,?plays?superior?absorbent,?water?retention.?A?contact?with?moisture,?the?adsorption?speed,?stored?in?the?inside?of?cotton.?(Softness)?soft?contact?will?not?scratch,?moist?state?softness,?flexibility,?especially?when?you?do?not?hurt?the?surface?of?the?object?as?the?cleaning?materials?and?cleaning?materials.
