特色标签:人性化设计,操作简单方便
纸与纸板吸收性测定仪(吸水仪,吸收仪,吸水率)产品简介
QD-3026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。本仪器主要用于测定施胶纸和纸板包括瓦楞纸板的表面吸水性。本仪器只是测定纸与纸板表面吸水性,但不适用于准确评价纸或纸板的书写性能。
纸与纸板表面吸水量(Cobb)值定义: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。
纸与纸板吸收性测定仪(吸水仪,吸收仪,吸水率)本仪器符合以下标准:
ISO535—1991纸和纸板吸水性的测定——可勃(Cobb)法
GB/T1540—1989纸和纸板吸水性的测定法(可勃法)
QB/T 1668:吸水性的测定法(可勃法)

COBB Absorption Tester Brief Introduction:
QD-3026 Type COBB Absorption Tester is mainly used to measure the surface water absorption of sized paper and cardboard, including corrugated fiberboard. Paper and board-determinator of water absorption is a frequent laboratory testing instrument developed by us according to national standards.
But it may be not suitable for paper and cruddy paper with a density lower than 50g/m2. Likewise, it may be not applicable for loose paper (for example, newsprint) or unsized paper (for example, blotting paper) or other paper with high water absorbability.This instrument is only capable of testing surface water absorption of paper and board. It is not applicable to exactly evaluate the writing performance of paper and board.
