ANTIFRICTION COAT FOR GUIDE PROFILE Russian patent published in 2002 - IPC

FIELD: erection and construction of different structures. SUBSTANCE: antifriction coat for guide profile is just layer obtained from melt of preliminarily granulated composition and provided with sliding surface for member brought in contact with this layer, preferably those made from polymer or provided with polymer coat made from mixture of polyethylene of high and medium density at ratio of 5:95 to 95:5, respectively at content of 1 to 20 mass-% of silicone rubber and preferably having roughness of 0.05 to 5.0 mkm of surface of sliding layer at arbitrary direction of irregularities to ensure friction coefficient in polymer-polymer pair of 0.18 to 0.40. EFFECT: reduced force of motion of member placed in profile; enhanced reliability of motion in case of deflection from rectilinearity of its sections. 6 cl, 3 dwg, 4 ex
