The slightest edge
Lignin fiber
Lignin fiber is an organic fiber, mainly used in pavement laying, is an indispensable stabilizer. Lignin fibers are usually flocculent, and sometimes lignin fibers used as stabilizers in asphalt mortar mixes are granular.
Today Xiaobian share for everyone dry goods: lignin fiber has the pros and cons, you will identify it?
With the lignin fiber to bring us a lot of benefits and the use of a wide range of the market, the sale of lignin fiber manufacturers also increased by a lot of time, which also makes the market quality of lignin fiber products appear good and bad The phenomenon. So how can you quickly and simply buy high quality lignin fibers? The following silk edge and share with you how to identify lignin fibers have advantages and disadvantages!
One smell smell
High-quality fiber has the characteristics of environmental protection, so that the smell will be very light, and no smell of irritating taste, but the identification of poor quality fiber method is very simple, there is pollution and his taste is very strong, not only this will stimulate people's sense of smell organ.
Second, visual inspection
High-quality fiber, the length of tidy, light and white, the thickness of the uniform, and silk, silk, thick wire, roll wire, grease wire, knot filament and impurity content less or not for high quality lignin fiber, of course this is the opposite Is the poor quality of the fiber.
Third, the water soluble
500ML of water into the two cups, and then each of the water cup into the 0.4G lignin fiber, and then stirring for 10 seconds after all observed, high quality will be dispersed evenly, suspended in the water. And poor quality fibers can not be distributed evenly or into a group-like distribution, flocculent suspended water or underwater.
Four, in addition to water
Poor lignin fibers contain moisture, but this moisture is difficult to find and feel through the feel or touch, if the water content of 5% then a kilogram of water content of the fiber is actually only 95 percent, So that the price of fiber is the original price of 1.05 times.
Five, sun exposure
Lignin fiber, due to lower costs, there is no anti-ultraviolet treatment, and lignocellulosic fiber in the sun under the next one or two years to lose strength, so lignin fiber in the concrete is difficult to play its long-term role. As long as the site site sampling (to strictly identify the filament and the site of the site of the polypropylene fiber short wire consistent), after a long period of sun and night exposure, and then detect the tensile strength can be distinguished.
The slightest message
Did the big guys learn? When buying lignin fiber, hope that the above method can
