一、產品簡介
本儀器是紙和紙板表面吸水性試驗的常規儀器,亦稱為紙張表面吸收重量測定儀。這種儀器採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儀。本儀器主要用於測定施膠紙和紙板包括瓦楞紙板的表面吸水性。本儀器只是測定紙與紙板表面吸水性,但不適用於準確評價紙或紙板的書寫性能。本儀器符合以下標準:ISO535—1991 紙和紙板吸水性的測定——可勃(Cobb)法;GB/T1540—1989 紙和紙板吸水性的測定法(可勃法)
紙與紙板表面吸水量(Cobb)值定義:單位面積的紙和紙板在壓力、溫度下,在規定時間內表面所吸收的水量,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。
二、技術指標

The apparatus is the surface of paper and chipboard absorption test of conventional instruments, also known as paper surface absorption weight measuring instrument. This apparatus using a resorbable test methods of Cobb ( Cobb ) test, thus also called Cobb absorption tester. The instrument is mainly used for the determination of sized paper and paperboard includes a corrugated surface water absorption. This instrument is determination of paper and cardboard surface water, but not suitable for accurate evaluation of paper or paperboard writing performance. The apparatus to meet the following criteria: ISO535 - 1991 paper and board - Determination of water absorption -- Cobb ( Cobb ) method; GB/T1540 - 1989 paper and board - Determination of water absorption method ( Cobb method )
紙與紙板表面吸水量(Cobb)值定義:單位面積的紙和紙板在壓力、溫度下,在規定時間內表面所吸收的水量,以g/㎡計。具體公式如下:C=(G2-G1)×100。
Paper and paperboard surface water quantity ( Cobb ) definition: value per unit area of the paper and board at a certain pressure, temperature, within the specified time surface absorbed by the water, to g/ ㎡meter. The formula is as follows: C= ( G2-G1 )× 100.
式中:C —— 可勃吸水值;
Type : C -- Cobb water absorption value;
G2 —— 吸水後稱出之試樣質量;
G2 -- after the water called the sample quality;
G1 —— 吸水前稱出之試樣質量。
G1 -- formerly known as the sample quality water.
