How to identify the quality of toilet paper and quality testing equipment selection
According to the National Institute of Quality Supervision, the general quality inspection of toilet paper, tissues, and napkins generally detects the following 9 performance indicators: the appearance of toilet paper, the basis weight of toilet paper, the whiteness of toilet paper, the lateral suction height, and the transverse tensile index strength , vertical and horizontal average softness, hole, dust, microbes and other indicators.
1. Toilet paper dust degree: Popular point is that there are not many paper dust particles. Toilet paper If the raw material is wood pulp, the dust level is generally not a problem. However, if recycled waste paper is used as raw material and the process is not properly handled, the dust level will be difficult to reach. The degree of dustiness affects the appearance and hygiene index of toilet paper. Dust measurement instrument: ZCA-1 dust tester.
2 Toilet paper hole hole: The hole eye index is the limitation on the number of holes on the wrinkle toilet paper. The hole hole will affect the use of the paper. The excessively holed wrinkle toilet paper is not only poor in appearance, but also easily damaged in use. Wipe effect.
3. Appearance of toilet paper: The first thing to look for is the soft packaging of toilet paper. When selecting toilet paper, you should first check the outer flexible packaging. The product's packaging heat seal should be flat and firm, no damage seal, and the seal integrity; the manufacturer should be printed on the name of the manufacturer, date of manufacture, product conformity level, according to the national standard number, the implementation of the health standard number (GB20810- (2006) and other information. The second look at the appearance of the paper, the paper surface should be clean, there should be no obvious dead folds, incomplete, damaged, hard blocks, grass ribs, pulp groups and other paper diseases and impurities, the paper should not be used when serious hair loss, The phenomenon of powder off, there should be no residual printing ink in the paper.
4. Toilet paper quantitative: Quantitative and divided into two kinds: The first refers to the amount or the number of sheets is not enough, according to the relevant provisions, generally the net content of 50 grams to 100 grams of goods, the negative deviation must not exceed 4.5 grams; 200 grams to 300 grams of goods must not exceed 9 grams. The second refers to the quantitative weight determination of sanitary paper, measured with a standard 100 cm2 weight, expressed in g/M2. Quantitative instrumentation: DL-100 Quantitative sampler + JT electronic balance.
5. Toilet paper absorbency: The water droplets can be seen on the top of the absorption rate, the faster the faster the water absorption. The toilet paper can also be cut into vertical strips, and the bottom of the strips can be placed in water. The water absorption performance of the toilet paper can be determined by looking at the changes in the water absorption height at standard time. Water absorption height measurement instrument: XSL-1 water absorption tester.
6. Transverse tensile index of toilet paper: it is the toughness of paper, and it is easy to break when used. Pure wood pulp paper has a large tensile strength, good toughness, and is not easily broken due to its long fibers. Tensile Strength Tester: WDK-01 Tensile Strength Tester.
7. Toilet paper whiteness: Toilet paper is not as white as possible, it may be added with an excessive amount of fluorescent bleach. Fluorescent agents are the main cause of dermatitis in women and may cause cancer in the long term. How do you tell if there is an excess of fluorescent bleach? First, the natural ivory should be seen with the naked eye, or the toilet paper should be exposed to ultraviolet light (such as a money detector). If blue fluorescence appears, it will prove to contain a fluorescent agent. Although the brightness is too low, it will not affect the use of toilet paper, but it shows that the use of raw materials is relatively poor, but also try not to use such products. Whiteness measuring instrument: BD-48 whiteness measuring instrument, ZF-6 three-purpose ultraviolet analyzer.
8. Toilet paper softness: This is an important indicator of toilet paper products. Good toilet paper should give people a soft and comfortable feeling. The main factors affecting the softness of toilet paper are the raw materials and creping process of toilet paper. In general, cotton pulp is better than wood pulp, wood pulp is better than wheat straw pulp, and toilet paper with softness exceeding the standard is rough to use. Softness measuring instrument: ZRD-1000 softness tester.
All in all, good-quality toilet paper, paper towels, and napkins are generally natural milky or ivory. The texture is even and delicate, the paper surface is clean, there is no hole, there is no obvious dead folds, dust, grass weave, and the thickness is uniform and tensile strength is large. Soft feel and so on. Low-grade toilet paper, paper towels, and napkins look dark gray and contain impurities. If you touch it with your hands, you may even lose powder, discolor or even lose hair, have poor water absorption properties, low tensile strength, poor softness of hand and other quality problems.
