Abstract
Przedmiotem zgłoszenia jest sposób otrzymywania proszku polietylenowego o jednorodnym uziarnieniu w trakcie jego strącania z rozpuszczalników organicznych. Sposób otrzymywania proszku polietylenowego o jednorodnym uziarnieniu podczas krystalizacji polietylenu z roztworu w rozpuszczalniku organicznym takim jak octan i-amylu, octan n-amylu, i-butynian i-butylu, propanian n-propylu, propanian n-butylu lub heptan-2-onie, charakteryzuje się tym, że w trakcie krystalizacji materiał roztworu chłodzony jest z szybkością nie większą niż 0,05°C/min w trakcie ochładzania roztworu od 110°C do 105°C, przy jednoczesnym turbulentnym mieszaniu.The subject of the application is a method of obtaining polyethylene powder of uniform grain size during its precipitation from organic solvents. The method of obtaining polyethylene powder of uniform grain size during crystallization of polyethylene from a solution in an organic solvent such as i-amyl acetate, n-amyl acetate, i-butyl i-butylate, n-propyl propanoate, n-butyl propanoate or heptan-2-one, is characterized in that during crystallization the solution material is cooled at a rate of not more than 0.05°C/min during cooling of the solution from 110°C to 105°C, with simultaneous turbulent mixing.
