Polypropylene fiber identification method a lot, you know a few?
Identification of polypropylene fiber bunch, master of several commonly used identification methods, to avoid being cheated by the merchant. The following manufacturers specializing in the production of polypropylene fibers on details for you to identify knowledge ~
Contrast visual method: high-quality fiber, length neat, uniform thickness, color light pale light. And less silk, silk pulp, thick silk, silk, oil silk, silk and clumping or no impurities are of high quality; rather inferior person.
Contrast water bath method: 500ml water into two cups in the same specification were added 0.4g fiber, stirring after 10 seconds observed quality are dispersed and suspended in water; inferior who can not be uniformly dispersed or slug, tufted suspended in water or underwater.
Odor identification method: high-quality fiber: environmental protection, tasteless without stimulation; inferior fibers: pollution, Sauvignon strong irritant.
Remove the water law: the poor quality of polypropylene fiber and some contain water, dried by drying or method can measure its water content, although the low price of the fiber, but contains in selling water. Assume a moisture content of 5%, then 1 kg fiber containing moisture in fact only 95% of the fiber, and fiber prices will be 1.05 times the original price.
Sunlight law: poor quality polypropylene fibers, due to lower costs, there is no after UV treatment, and polypropylene fiber in the sunlight next year or two will lose strength, so low-quality polypropylene fibers in concrete long-term is difficult to play its effect. As long as the sampling at the site, after a long time the sun dew, the tensile strength can then detect the difference.
The above method for everyone in the purchase of polypropylene fibers for future reference Oh! Of course, we Fiber Co., Ltd., Jiangsu Sisiyuan polypropylene fiber quality and quantity of production, pack your satisfaction, you can come here to worry about throwing everything!
