Abstract
Generation of materials with managed voids rating in process of forming of biological polymer of NA-sodium carboxymethyl cellulose with fine particles of AlOOH for production of functional coatings
Incoming article date: 07.12.2017New highly-porous film materials were created based on NA-sodium carboxymethyl cellulose, modifyed by particles of AlOOH. Forming of covers happen as a result of relatively not high temperatures (for about 55 degrees of centigrades). A regression model was suggested which described interrelation between sizes of forming porouses in the film cover with its composition. The ability was shown to manage physical specification of the cover which named surface porosity by changing containing of AlOOH in the composition. It was shown up that porouses were formed sizes between 300 mircometers and 2500 mircometers in proccess of curing of the cover while containing of boehmite in the composition. It was discovered that the general surface porosity was 65%, and the depth of cover was 600 mircometers. The ability was shown to create covers with sliding properties as exemplified in closing of pores by solid lubrication MoS2. It was discovered that it was observable down drag by 30-50% in response to application of covers on steel faces adding down of frictional force.
