Foreword

GB/T 22805 "Paper and board - Determination of grease resistance degree" is divided into two parts. --- Part 1. osmosis; --- Part 2. Surface Exclusion Act. This is Part 2. The partial modification of the use of ISO 16532-2.2007 "Paper and board Determination of grease resistance - Part 2. Surface Exclusion Act." This part of ISO 16532-2. Compared to 2007, the main differences are as follows. --- Normative references in ISO standards into its corresponding national standard, GB/T 450 paper and cardboard sample And vertical and horizontal sample taken, positive and negative determination (GB/T 450-2008, ISO 186.2002, MOD); --- Normative references in ISO standards into its corresponding national standard, GB/T 10739 paper, paperboard and pulp Sample processing and testing standards atmospheric conditions (GB/T 10739-2002, eqv ISO 187.1990); --- Modify the results of the representation with minimum resistance, lipid values \u200b\u200bshows the test results, compared with a mean value of the test results so that better meet With the requirement to safeguard the interests of consumers.

3 Terms and Definitions

The following terms and definitions apply to this part of the GB/T 22805 of. 3.1 Paper and paperboard resistance to surface grease stain formation and penetration ability. 3.2 Paper and paperboard capacity grease-resistant surface wetting response. 3.3 After a set number of the test solution successively drop in paper or cardboard surface, it did not occur in the paper or paperboard surface color deepened wetting The maximum number of tests prior to the reaction solution. NOTE. grease-resistant high value indicates that the sample has good resistance to grease performance. Principle 4 Castor oil was mixed with the two solvents of different proportions solution from low to high numbers form a set of test solutions. Do not The same number of test solutions with different permeability. The test solution was dropped on the surface of the specimen was measured at the surface of the sample did not produce dark spots The maximum number of test solution is resistant to grease the value of the sample.
