Low compression ratio mainly produces low-density raw material belts and elastic products; medium compression ratio mainly produces high-density raw material belts, extruded tubes, etc. Can not eventually become a useful product, in fact, the processing process of the material is the process of oriented fiberization of the material.

Dispersing resin is an important variety of polytetrafluoroethylene, it is the product of TFE monomer in the medium, dispersed into an emulsion state by the emulsifier for polymerization.. The processing of dispersed resin is carried out with reference to paste extrusion. Usually the extrusion processing is carried out with additives, which is generally referred to as paste extrusion, so The additives added are generally hydrocarbon-containing oils, which are used as additives for extrusion to provide lubrication and reduce molding pressure.

It is a white powder resin with a bulk density of about 500 g/L and an average particle size of 450 to 550 m. According to customer requirements and internationally popular classification methods, generally based on the compression ratio, it is divided into low compression ratio (less than 500:1), medium compression ratio (1000:1 500:1), and high compression Ratio (more than 1000:1).; high compression ratio mainly produces thin-walled small-diameter pipes, Wire and cable, etc.

Under pressure, it will agglomerate into agglomerates; secondly, during screw extrusion, the raw material is subjected to non-directional force, which makes the material produce a non-directional PTFE adhesive tape Manufacturers fiber form, and the material cannot be combined to form a continuous extrusion process. There are two reasons: first, the dispersing resin is very soft. Spiral extrusion is not suitable for dispersing resins

Bonding process: Wipe the surface to be adhered with acetone or ethanol solution, dry, apply T530 glue directly on the surface to be adhered, bond and apply pressure to bond, and it will be adhered firmly in 5-10 minutes. Bonding process: wipe the surface to be adhered with acetone or ethanol solution, and dry; brush the surface to be adhered with primer P-10, and dry (3~5min); use super glue SG-506 to quickly bond Connect, 3~8s to stick firmly.

They are typical and conventional, but they are also conservative. Their advantage is that the total time from workpiece processing to bonding to use does not exceed 10 minutes, and their shear strength can be as high as 9-16kg/cm2. The processing and bonding time of a workpiece takes at least 24 hours, and it is possible that this workpiece is in the entire product production cycle.

SG-P-10 Adhesive This adhesive is a two-component, solvent-based adhesive bond composed of primer P-10 and instant super glue SG-506, suitable for PTFE and PTFE workpiece materials Fast bonding.Sodium naphthalene solution treatment bonding method, sodium liquid ammonia solution treatment bonding method, and surface bonding without special treatment are three types of bonding methods. Only a few hours or even a few minutes are occupied in the schedule.

T530 adhesive The adhesive is a one-component, solvent-based adhesive, suitable for self-adhesive PTFE and PTFE or PTFE and stainless steel mutual adhesion.. From the perspective of efficiency, they are obviously not ideal, because fast-paced and high efficiency are very important in modern production. They have a common disadvantage: bonding It takes a PTFE Coated Fabric long time and the process is complicated. So, is there a simpler and faster bonding method? Here are two new adhesives, which can solve this problem well
