Tough cardboard set In general the amount of 600g/m2 or more. Principle 4 The constant temperature and humidity balance after the treated sample was cut into a predetermined sample size, soaked in distilled or deionized water, until the layers can And the fiber separated from each other without being torn up. Will stick to the surface layers of the paper is not absorbed by the adhesive layer is removed and then placed in the sample (105 ± 2) ℃ dried to constant weight. After drying the sample is placed under constant temperature and humidity conditions for processing until the balance, and the layers were measured Quantified. For waterproof cardboard or paperboard easy to layer, it can be soaked in water heated to about 80 ℃. If it still can not heat-treated Hierarchical, not hierarchical quantitative determination. 5 equipment, instruments and reagents 5.1 cutter or sampler Within ± 1% error range specified area by cutting out a predetermined repeat performance sample area of \u200b\u200b95%. Such as cut-sample accurate When the degree is not reached, samples should be tested separately for each area, and then calculate quantitative. 5.2 Balances Over the entire weighing range is used, the measurement error should be within ± 0.5% of actual value, and can measure the weights of the ± 0.2% of Variety. 5.3 dip tank Enough to accommodate 10 specifications for 100mm × 100mm or 250mm × 250mm of sample and the sample was placed vertically on grid On, and completely submerged in water. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 22872-2008_English be delivered?Answer: Upon your order, we will start to translate GB/T 22872-2008_English as soon as possible, and keep you informed of the progress.
