Polyanionic cellulose is mainly used in oil drilling. Yield Point (yield Point refers to the stress value in the yield stage when the material is stretched) as an important indicator of polyanionic cellulose has been increasingly used in product testing.
The Yield Point calculation formula is as follows:
Yield Point = the value measured at 600rpm of the B-type viscometer - 2* the value measured at 300rpm
Especially in the export of polyanionic cellulose, more and more customers often test this value as an important indicator of whether the product is qualified.
