METHOD AND DEVICE FOR APPLYING SUBSTANCES ONTO SURFACE TO BE TREATED Russian patent published in 1999 - IPC

FIELD: materials treatment. SUBSTANCE: preliminarily, substance is placed into container interconnected with coating-application device to enable dosed delivery of substance to be applied. Minimum dose value V₁ and its maximum value V₂ delivered in unit time are chosen within the limits 0.18 ≤(V₁+αV₂)≤ 4.6 where α is experimental coefficient depending on viscosity, porosity, and flowability of substance within the limits 0.18 ≤α≤ 3.6. Device-mediated extraction of volumes and their displacement on their application area is performed using energy doses E₁ which are interrelated with total energy dose E₂ consumed for displacement of device relative to surface being treated and/or applying substances, or with energy capacity E₂ of autonomous power sources by the following inequality: 1 ≤(βE₁+E₂)/E₂≤ 6.1 wherein β is experimental coefficient depending on plasticity and adhesive characteristics of substance within a range of 0.27 ≤β≤ 5.3. Device is interconnected with additional volume of substance to be applied and with mechanisms for dosed delivery of that substance and its displacement to desired surface region. Value V₃ of volume of substance to be applied is interrelated with total volume V₄ occupied by device by the following inequality: 1.01 ≤(γV₃+V₄)/V₄≤ 2.3 wherein γ is experimental coefficient depending on porosity of substance and productivity of device within the limits 0.65 ≤γ≤ 1.5. Constructional features of dosed delivery mechanism are determined by value of volume of substance being delivered in unit time within the limits 1.00006 ≤(λV₅+V₃)/V₃≤ 3.8 where λ is experimental coefficient depending on porosity, hardness, and flowability of substance within a range of 0.14 ≤λ≤ 2.8. Ratio of minimum cross-section of device L₁ to its maximum dimension L₂ is chosen within the limits 0.74 ≤(L₁+δL₂)/L₂≤ 3.3 where δ experimental coefficient depending on configuration of device and ergonomic requirements of potential consumer ranging from 0.68 to 2.3. EFFECT: improved consumer's characteristics of device. 2 cl, 1 dwg
