Food grade silicone tube strength and what relationship?
Food grade silicone tube in the life of the role is very large, sometimes need to compressive strength and wear resistance, the following Xiaobian introduce food grade silicone tube strength and what relationship?
First of all, the larger effect of fiber material fatigue properties and rubber adhesive performance, select the appropriate fiber line is the key. Domestic fiber lines are mainly cotton, dipped artificial line, vinylon thread, polyester thread, gumming polyester line. Gumming polyester line is more ideal, it not only makes the greatly strengthened the bearing strength of the hose, the hose is the adhesion strength between the layers increase, Qiyu plastic products factory using this line in production as a reinforcing material for rubber hose, the effect is very ideal.
Secondly, the number of layers should be calculated according to the standard requirements of working pressure usually adopt the following fiber winding:
PB=0.735N. The oyster 'C2 / (D;' g)
Type: P. A hose compressive strength, MPa;
Total root IV a winding number;
Luo a single fiber line strength, N / root;
A calculation of D1 diameter, EM; C2, G, a correction coefficient.
Hose winding density size fiber winding, directly affect the bonding strength of hose pressure and interlayer. If the winding density, compressive strength of the hose can be improved, but the adhesion strength between the layers of the hose is also decreased (by adding specific system, also can make the effect of reducing). If the winding density is too small, so that the fiber winding layer midline line gap is enlarged, with the combination of penetration for the internal, external, glue, adhesive strength and compressive strength increase, but will also decline. So the choice of reasonable density of fiber winding hose, for improving the quality of products, make full use of enhanced strength important fiber material.
In short, food grade silicone tube also need to pay attention to use in order to extend the life of.
