Production process:
For the treatment of raw cloth, the substrate used by the abrasive belt includes cloth, paper and composite base. The main processes of cloth base treatment, such as scraping, singeing, dewaxing, dyeing, dipping and scraping, stretching and calendering, are selected according to different requirements. Large roll manufacturing mainly includes trademark printing, gluing, sand planting, re gluing, drying and other main processes, which are completed in one production line. In addition, the post-treatment of large rolls includes post curing, storage, humidification, softening, etc. after the emery cloth is rolled out of the drying room, it can enter the conversion process after a series of treatment.
Finally, there is the process of conversion. The so-called conversion refers to the process of converting the large roll of abrasive cloth into abrasive belt, disc-shaped, sheet-shaped and other shaped products.
Storage instructions:
Firstly, the sand belt should not be stored in a place with large temperature and humidity changes. The ideal temperature is 18-220c; The ideal humidity is 40-65%, because too high a temperature will make the adhesive aging and reduce the service life of the abrasive belt. Too high or too low humidity will cause certain deformation of the belt, and the deformation will reduce the bonding strength of the adhesive layer of the belt.
In addition, when the damp abrasive belt is grinded, the grinding material is easy to adhere to the surface of the abrasive belt, reducing the service life of the abrasive belt. High temperature and low humidity have a great impact on the paper-based sand belt, which makes the paper-based sand belt brittle and easy to be broken and scrapped in use.
