Interleaving paper mainly interleaves between metal sheets to avoid the scratch caused by the friction between two layers.
Interleaving paper mainly interleave between metal sheets to avoid the scratch caused by the friction between two layers. The interleaving paper must overcome high-speed moving, high tension, high temperature and slip caused by temperature drop between sheet layers. The interleaving paper must have characters of heat-resistant, high surface strength, smooth, anti-aging etc. And must be strictly controlled the content of halogen, sulfate and other impurities to extremely low in order to prevent the steel plate from scratches and discoloration in the course of long-term storage and transportation.
Surface hardness of stainless steel is low and has extremely high demand on surface finish, so the interleaving paper surface must not contain non-fiber impurity such as pulp ball, flinty dust etc.
The moving speed of stainless steel in the production process is very fast and changes frequently, therefore the interleaving paper must have pull-resistance and anti-impact properties to avoid breaking off. The tie-in rate of paper page must be close to zero.
In order to reduce costs, the process interleaving paper can be reused for 5 to 10 times, so besides the high-temperature and high-pressure endurance ability we must guarantee the sides and internal tension maintain the same while winding so that the surface maintains neat for the benefit of the repeated use in the factory.
The stainless steel interleaving paper is divided into the white and the brown.
The stainless steel interleaving paper is divided into 32gsm, 35gsm, 40gsm, 42gsm, 60gsm according to the weight, and we also can produce special paper according to the customers production characteristic to satisfy the operation requirements of customers and reduce the their cost.
Specification: 1000, 1220, 1250mm is common width, also can produce width between 100mm~2700mm according to the customers requirement.
Application field of interleaving paper for stainless steel:
1. Manufacturing and processing enterprises of cold-rolled stainless steel sheet: Used in rolling, acid wash, refining and finishing process in the stainless steel production to protect surface to be bright. It can be used repeatedly.
2. Manufacturing and processing industries of copper, aluminum sheet: Used as liner in manufacturing process of copper and aluminum products.
