紙與紙板吸收性測定機(吸水機,吸收機,吸水率)產品簡介
QD-3026紙和紙板吸收性測定機是紙和紙板表麵吸水性試驗的常規機器,亦稱為紙張表麵吸收重量測定機。這種機器采用吸收性試驗多種方法中的可勃(Cobb)試驗法,因此也稱為可勃吸收性測定機。本機器主要用於測定施膠紙和紙板包括瓦楞紙板的表麵吸水性。本機器隻是測定紙與紙板表麵吸水性,但不適用於準確評價紙或紙板的書寫性能。
紙與紙板表麵吸水量(Cobb)值定義:單位麵積的紙和紙板在一定壓力、溫度下,在規定時間內表麵所吸收的水量,以g/㎡計。
具體公式如下:C=(G2-G1)×100。
式中:C —— 可勃吸水值;
G2 —— 吸水後稱出之試樣質量;
G1 —— 吸水前稱出之試樣質量。

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.
