With the rapid development of industrial technology, abrasive belt grinding with high efficiency, high economy and a wide range of applications is becoming more and more important in the wood processing industry. In order to improve the quality and grade of products, as an advanced processing technology, many enterprises are using or preparing to use abrasive belt grinding.
In order to better serve the users, make the abrasive belt in the best state when in use, and give full play to the superiority of abrasive belt grinding, some knowledge on the storage and use of abrasive belt is now introduced to you.
The storage of the china abrasive belt is very critical to the use of the abrasive belt, especially for the wide belt. Ideal storage conditions and reasonable storage methods can ensure that the abrasive belt is used in the best state.
1. Requirements of temperature and humidity
The abrasive belt should not be stored in a place with large changes in temperature and humidity. The ideal temperature is 18-220°C. The ideal humidity is 40-65%. If the temperature is too high, the adhesive will be aged and the service life of the abrasive belt will be reduced. Synthetic fiber matrix belts (such as polyester cloth belts) are sensitive to cold and cannot be stored in cold warehouses.
Too high or too low humidity will cause a certain deformation of the abrasive belt, and the deformation will reduce the bonding strength of the abrasive layer of the abrasive belt. In particular, excessive humidity has a serious impact on the sand belt. In addition to the water-resistant abrasive belt, the general abrasive belt is used after being wet, and it is prone to wrinkles and other phenomena, which makes the abrasive belt scrapped. In addition, when the wet abrasive belt is ground, the grinding object is easy to adhere to the surface of the abrasive belt, which reduces the service life of the abrasive belt. High temperature and low humidity have a great influence on the paper-based abrasive belt, which makes the paper-based abrasive belt brittle and easy to break and scrap when used.
2. Storage
The warehouse where the abrasive belt is stored should be cool, dry and ventilated. The abrasive belt should be placed on the cargo rack, not on the ground. The cargo rack should be kept at a distance of about 200-500mm from the ground and wall, and at the same time, it should be avoided close to heat dissipation and drainage device. Try not to open the box for unused abrasive belt. Heavy objects should not be stacked on the belt packing box to avoid creases and cracks on the belt.
The storage of the abrasive belt is important, but if the abrasive belt cannot be properly treated before use, it will still seriously affect its performance.
1. Suspension of abrasive belt
The belt should be hung for at least 2-5 days before use, its purpose is to eliminate the curling caused by packaging.
Hang the unpacked abrasive belt on a 100-200mm diameter pipe or on a special belt support frame. The length of the pipe should be greater than the width of the abrasive belt, otherwise the abrasive belt will easily fall off or produce a bell mouth. The pipe should be in a horizontal state, otherwise the edge of the abrasive belt will be easily damaged.
The ambient temperature and humidity of the suspended abrasive belt should meet the storage conditions of the abrasive belt. The easiest way is to keep it dry with several 40W or 64W light bulbs in a sealed room.
2. Visual inspection
Before using the suspended abrasive belt, the necessary appearance quality inspection should be done to check whether the abrasive belt joint is smooth and firm, whether there are holes, sand lumps, lack of sand, glue spots and wrinkles on the surface of the abrasive belt. Whether the edges of the abrasive belt are neat And whether there is a crack, if there is a small crack on the edge, it will not affect the use after cutting (cut into a circular arc).
