Abstract
Inventia se refera la un procedeu de obtinere a purtatorilor pentru developare, utilizati în procesul de copiere electrostatica. Procedeul, conform inventiei, consta în cufundarea pulberii de fier într-o compozitie de fasonare avînd compozitia: Zn:8,5-17,5 g/l; Fe:0,5-1,0 g/l; P2O5:12,4-31,0 g/l; S:0,1-0.5 g/l; N2:0.3-0,85 g/l; Ni:0,2-0,85 g/l; Na:0,05-0,8 g/l; Ti:0,2-0,7 g/l si aplicarea apoi a cel putin doua straturi de rasini sintetice insolvabile în apa si/sau în solventi organici, rasini cese pot încarca static, aplicarea fîcîndu-se dintr-o solutie de 8-40% în greutate rasina de uree polimerizata la cald si/sau 6-30% în greutate rasina de silicon si 30-86% solvent organic si /sau apa, straturile aplicate fiind din rasini sintetice dif erite.
