Hot Air Stenter , a kind of equipment in the textile printing and dyeing factory, is characterized by stretching and tensioning the fabric by heating and stretching to the sides to make the width and width of the latitude uniform. Therefore, the products are very beautiful, and the machine can also reduce the deformation of the fabric during the cutting and sewing process, so it plays an important role in the textile printing and dyeing factory.
In daily operation, 70% of the Hot Air Stenter failure is caused by poor lubrication, so choosing high temperature grease is crucial for the normal use of the Hot Air Stenter. Then, what are the characteristics of high temperature grease? What do we need?
First, anti-watering and corrosion resistance
Due to the working environment of the Hot Air Stenter, there are certain requirements for temperature and humidity, and the high-temperature grease used in it has many opportunities to contact with moisture in the air, and it is easy to emulsify the fat due to the immersion of water, and mechanical corrosion occurs.
Second, the lubrication characteristics
The Hot Air Stenter generally lasts for a long time and is subjected to a large load, which increases the friction of the contact surface of the Hot Air Stenter, thereby causing wear to the bearing and affecting its service life.
Therefore, the Hot Air Stenter high-temperature grease needs to have good lubricating properties, has excellent film forming and bearing capacity, and can provide excellent anti-wear lubrication protection at high temperatures.
Third, high temperature and oxidation stability characteristics
Under the long-term working of the Hot Air Stenter, the internal working temperature will continue to rise, which will easily cause the deterioration of high-temperature grease, resulting in the loss of high-temperature grease in the lubrication part and loss of lubrication.
Therefore, the Hot Air Stenter high-temperature grease should have excellent high temperature and oxidation stability characteristics, the temperature needs to reach 250 ° C, not only will not deteriorate, lose at high temperature, will not dry out, or form harmful impurities, to ensure that the lubrication parts are at high temperatures for a long time. Normal work.
