EPDM sealing stripIs a common mechanical seal, widely used in various mechanical equipment. The manufacturing process includes the following steps:
Raw material preparation:EPDM sealing stripThe required raw materials include sheet, glue, acrylic and so on. Among them, the board needs to choose qualified SPCC (non-toxic polypropylene) board, glue needs to choose stable quality glue, acrylic needs to choose high transparency, good toughness of acrylic.
Mixing material: mix the plate, glue and acrylic in a certain proportion and mix them evenly.
Apply primer: Apply the mixed material to the surface of the board to form a layer of primer. The function of the primer is to enhance the adhesion and corrosion resistance of the sealing strip.
Grind the surface: grind the plate coated with primer to remove the burrs and bumps on the surface and make it flat and smooth.
Spraying topcoat: evenly apply the adjusted topcoat to the surface of the plate to form a protective film. The function of the topcoat is to enhance the aesthetics and corrosion resistance of the sealing strip.
Drying: Place the sealing strip coated with the topcoat in a dry environment for drying to cure the topcoat. The drying time is usually 2-3 hours.
Packaging: The dry sealing strip is packaged, and measures such as moisture-proof and dust-proof should be paid attention to during packaging to ensure the quality and service life of the sealing strip.
in manufacturingEPDM sealing stripIn the process of, need to pay attention to the following matters:
Wear gloves and masks during operation to avoid exposure to harmful substances such as glue and acrylic.
When grinding the surface need to use sandpaper or grinding machine, can not use metal grinding tools, so as not to damage the surface of the sealing strip.
When spraying the topcoat, it is necessary to maintain the stability of the spray gun to avoid problems such as color difference and sagging.
During the drying process, it is necessary to pay attention to good ventilation to avoid deformation of the sealing strip due to lack of oxygen.
When packaging, it is necessary to pay attention to the moisture-proof and dust-proof measures of the sealing strip to ensure the quality and service life of the sealing strip.
Anyway,EPDM sealing stripThe manufacturing process is more complicated, but as long as the manufacturing skills and precautions are mastered, qualified sealing strips can be manufactured.
