Roll:The wear and tear life of the rolls varies depending on the process,production capacity,and on-site usage of each customer.
The maintenance of rolling rolls and the coating method of rust proof oil:
1.Rolls are prone to rusting in damp environments,and once rusted,it can cause unnecessary trouble in production.When the rusting is severe,the rolls need to be re polished!In view of this,when using the polar plate rolling mill,it is necessary to control the humidity of the production environment,and it is recommended to control it below 60%RH;
2.The uniformity of mixing(if there are particles)will directly affect the wear life of the rollers;
3.If the customer's polarizers are wide or narrow,it is necessary to periodically switch the left and right roller pressing positions;
4.After work,the scraper function should be turned off,and the scraper should not come into contact with the roller surface(if the scraper comes into contact with the roller surface,it will rust the roller surface).The scraper should be wiped clean with alcohol and kept clean to extend its service life;
5.After work,the roller surface should also be wiped clean with alcohol,and then wiped once with a dust-free cloth(as alcohol contains a small amount of water)to keep it dry and clean;
6.When not in use during shutdown or every few days,be sure to apply butter or spray rust inhibitor on the surface of the roller body for rust prevention.The specific operation method is as follows:
If not in use for a short period of time,the roller body can be cleaned and dried,and then temporarily coated with butter,or directly sprayed with rust inhibitor.During use,it is necessary to observe the roller surface in a timely manner.If there are any problems,corresponding remedial measures must be taken in a timely manner.
7.When not in use for a long time,it is necessary to apply a hard film anti rust oil on the surface of the roller body to prevent corrosion.The specific operation method is as follows:
Before applying oil,clean the surface of the roller body,dry it with a dry cloth,and then thoroughly dry it with a drying equipment.Then apply a layer of hard film anti rust oil,which must be evenly coated without any exposed white.After solidification,apply the hard film anti rust oil again,and finally dry the coated anti rust oil with a drying equipment.
Notes:
If there is rust on the surface of the rolling mill,no sandpaper or gauze can be used to wipe or polish it.If the rust is not serious,a felt can be applied with grinding paste to wipe the rusted surface;
When applying oil to the temporarily unused roller press rolls,it is necessary to maintain a certain gap between the two rolls to avoid inadequate application of rust proof oil;
▲The roller surface should not be damaged or scratched by hard alloys or sharp metal objects.During normal rolling,metal objects and other foreign objects should not be rolled.
