METHOD OF MANUFACTURING DOUBLE-LAYER ASSEMBLY WORK Russian patent published in 2001 - IPC

Abstract RU 2174915 C2

FIELD: polymer materials. SUBSTANCE: double-layer boron plastic/polypropylene assemblage useful for biological protection against neutron emissions is manufactured in thermoplastic automate by way of forcing polypropylene onto inner layer of boron plastic. Prior to be charged, polypropylene is mixed with 11-16% of powdered graphite plastic containing 75% artificial graphite and 25% polypropylene. EFFECT: avoided manual assemblage and improved neutron protection. 2 tbl
