Warm wind, come the spring, with the development of society, insiders all know the importance of polypropylene fibers in life, comes into its own through people continue to research, the products produced by its application to various fields. Xiao Bian today to pass a simple tips on how you can identify the polypropylene fiber quality.

 A polypropylene fiber function
High-quality fiber composite made of high quality fiber grade polypropylene material with the original special additives made; and defective fiber composite made from the powder or additives commonly used recycled materials and textiles generally.

Second, the cost of polypropylene fiber
Recycled polypropylene material compared with virgin polypropylene material, offer lower.

Third, the polypropylene fiber discern good and bad ways
 1. water bath comparative method:

        Take 500ml of water into two cups, respectively, participated in the same standard 0.4g fiber, mixing 10 seconds after investigation, were lax quality uniformly suspended in water; defective can not even lax or slug, tufted or suspended in water underwater.

 2. The odor discrimination law:

       High-quality fiber: environmental protection, tasteless no effect; defective fiber: pollution, Sauvignon influence is strong.

 3. The sunshine law:

        Defective polypropylene fibers, because the decline in the capital, without foundation UV disposal and polypropylene fibers in the sunshine next year or two would lose strength, the polypropylene fiber is difficult defective long time to develop their effect in concrete . Just at the site of sampling (to distinguish severe censorship and the construction site of the filament polypropylene fibers short silk common), after a long time of sun and dew, and the tensile strength can detect the difference.

 4. remove moisture law:

        Some defective polypropylene fiber is rich in water (manpower alone is difficult to feel), after drying or drying methods can measure its water content, although the fiber lower price, but it contains in selling water. Assumed moisture content of 5%, then 1 kg of water-rich fibers fact as long as 95% of the fibers and the fibers offer will be 1.05 times the original offer.

 5. cf. visual method:

        High-quality fiber, the length of regular, uniform thickness, color and light pale light. And less silk, silk pulp, coarse silk, silk, silk oil, silk and clumping or no impurities are of high quality; the contrary were defective.

 6. The detection method:

     Materials produced from recycled polypropylene fiber, the fiber:

① tensile strength is low, typically <350Mpa;

② elongation, typically> 60%;

③ poor alkali resistance, because mixing concrete and hardened concrete were strongly alkaline (pH≥12), in this environment the strength of the fiber will gradually decline, so that concrete results will be small play, concrete foundation can not progress mechanical function.

Xiao Bian sincerely hope that the above tips can be useful for colleagues who are! Jiangsu Sisiyuan sustained attention focused on fiber and polypropylene fiber engineering service number, Xiao Bian will bring you more exciting!

Sisiyuan, whereas love! Silk destined, lines connected, present and destined, connected line.

Fiber Co., Ltd., Jiangsu Sisiyuan Tips: polypropylene fiber only as a secondary reinforcement, not a substitute for structural reinforcing material (such as reinforcing steel), not to be used for the settlement and to resolve by force or impact cracking occasion can not be reduced because of the size of the primary structure of a fiber, a fiber construction and maintenance should be strictly in accordance with relevant state regulations and practices. In the storage process to prevent prolonged exposure to sunlight.
