How to deal with the fiberglass chopped strand mat uneven

Fiberglass chopped strand mat uneven is caused by production process winder, sedimentation control dispersion process! Chopped strand mat production enterprises more or less there will be unevenness in the process! Analysis of this phenomenon for several reasons:

1, yarn, yarn quality is not optimistic. We purchased yarn with coarse strip, uneven thickness. Which belong to the reason of yarn production. In the case of uneven yarn, chopped settlement passes, the same unit area of the mat will be caused some holes and uneven.

2, winding, spooling to find the thread into the hole chopped machine, there are dozens of stocks debris to enter dozens of short-cut machine hole. Strictly, a short-cut machine hole into one yarn, but some shift workers lazy, several strands of thread yarn simultaneously into a cutting machines hole, resulting in some machines bore no yarn can enter, and some machine hole in too much yarn, settlement dispersed unevenly.

3, the construction environment temperature, humidity, low temperature, high humidity will also not conducive to the yarn filaments dispersed.

For the above two cases you can use the following three methods to resolve:

1, purchase good quality yarn for production, requiring uniform thickness, moderate stiffness of the yarn, the yarn evenly distributed convenient short-cut settlement process. The quality of the yarn can directly affect chopped strand mat uniformity and quality, so choose high-quality glass fiber yarn is a prerequisites condition for produce high-quality and evenly chopped strand mat.

2. Winding. the stringent requirements that one hole for one wave of yarn, which makes the cut yarn can uniformly settlement. This requires construction workers to strictly responsible for the operation, who can not have the phenomenon of sabotage lazy. Should strict accordance with the requirements of the construction product uniformity will be greatly improved.

3, the above two methods strictly enforced if there will be uneven, you can adjust the throttle, which requires resourcefulness, where thick adjust where, once even we don’t need frequent changes in throttle.

4, environmental temperature and humidity, according to the actual situation to control, try to avoid the environmental and humidity affect the chopped strand mat production!
