DEVICE FOR FORMING OF ANISOTROPIC FILM Russian patent published in 2003 - IPC

FIELD: chemical industry, applicable for production of films or coatings possessing anisotropy of physical properties from the colloidal systems. SUBSTANCE: the device has at least one duct for supply of the colloidal system to the backing or the article and a plane face for action on the colloidal system on the backing or article. One of the duct walls at the outlet of the colloidal system to the backing forms with the plane face an obtuse dihedral angle, and the dihedral angle having a rib of the plane face as a vertex opposite the duct outlet is an acute one. EFFECT: produced films with an improved reproducibility of the parameters both on the film surface and in its thickness, as well as films with an enhanced anisotropy. 13 cl, 2 dwg, 1 ex
