Matters needing attention in the selection of felt sealing gasket

1. The unit volume weight (g/cubic centimeter) of felt will lose elasticity if it is too large, and the wear resistance will be lost if the unit volume weight is too small. Thickness and wool thickness have an impact on various properties. Users can choose them appropriately according to the use requirements. It is better to inform the use of the product before purchasing, so as to avoid affecting the production and use.

2. Felts of different varieties can be divided into special felts and general felts. Varieties are classified according to the size of raw materials, the weight per unit volume (i.e. the tightness of density) and the color. Technical requirements are classified according to the presence or absence of strength, elongation and capillary action. Users can choose according to their needs. When inspecting goods, this standard can be used to inspect.

3. Specification type description of felt: when ordering felt, we only need to put forward our own product number according to the standard category naming number, and at the same time put forward specifications such as thickness, length and width. If we need dyeing, we also need to improve the luster.

Notices for medium and coarse felt:

1. The density unit of felt is (g/cm_). Excessive density will lose elasticity, too low density will lose wear resistance. Thickness and wool thickness also have different effects on its performance. Users can choose or inform the use according to the use requirements, so as to avoid affecting the use.

2. At present, there are three kinds of felt: special felt and ordinary felt. The difference is divided according to the thickness, density and color of the wool; the technical requirement is divided according to the strength, elongation and capillary action, and the user can choose according to the need.
