可勃吸收性测定仪

KBX可勃吸收性测定仪(又称可勃吸水性测定仪、可勃吸水仪、吸水性测定仪、表面吸收性测定仪、纸张表面吸水率测定仪、吸水仪)  是根据GB/T1540-2002纸和纸板吸水性的测定法(可勃法)规定的基本参数和要求而设计的。此标准适用于测定各种纸或纸板表面的吸水性。但不适用于准确评价纸或纸板的书写性能。

KBX可勃吸收性测定仪产品功能

     纸与纸板表面吸水量(Cobb)值:单位面积的纸和纸板在一定压力、温度下,在规定时间内表面所吸收的水量,以g/㎡计。具体公式如下:C=(G2-G1)×100。式中:C-可勃吸水值;G2-吸水后称出之试样质量;G1-吸水前称出之试样质量。纸和纸板吸收性测定仪是纸和纸板表面吸水性试验的常规仪器,亦称为纸张表面吸收重量测定仪。这种仪器采用吸收性试验多种方法中的可勃(Cobb)试验法,因此也称为可勃吸收性测定仪。

KBX可勃吸收性测定仪产品特点:

1.金属圆筒内截面积为100±0.2㎝(相应内径为112.8±0.2mm),圆筒高为50mm,圆筒环面与试样接触部分应光滑。

2.吸水纸定量为200~250g/㎡,其吸收速度为75mm/10min。当吸水纸单层定量小于200~250 g/㎡时,可以用多层叠加以满足要求。 3.光滑金属平辊:辊的长度200±0.5mm,质量应为10±0.5kg。 4.试验用水量:100mm±5ml。

5.尺寸与重量:尺寸:<480×400×420(mm),

                        重量:28kg
