Coating process for European window production line

Abstract

The invention discloses a coating process for a European window production line. The coating process includes the steps of firstly, selecting laminated pine wood or catalpa wood 1m<2>; secondly, spraying mixed liquor (3) composed of 80wt% of water and 20wt% of basecoat by intermediate spraying; thirdly, using No.240 abrasive paper for sanding so as to flatten and remove burrs and wood ribs; fourthly, using a curtain coater to curtain at an oblique angle of 45 DEG with the coating amount of 20L / m<2>; fifthly, using No.320 abrasive paper to smooth the surface with penetrating; sixthly, coloring the surface, namely embellishing according to a finish reference color board with the coating amount of 0.3-0.4L / m<2>; seventhly, using No.400 abrasive paper to smooth the surface without penetrating; and eighthly, performing electrostatic spraying with 0.6-0.7L / m<2> finish. The intermediately sprayed mixed liquor is antiseptic. The wood ribs and burrs are removed for smoothing. Surface mild damage is subjected to puffing. After the intermediate spraying mixed liquor is used, two workers are omitted, labor cost is reduced by one fifth, efficiency is improved by 20%, and repair amount is lowered by 50%. The coating process is simple in process, and the coating effect is lasting.

Description

technical field [0001] The invention relates to a coating process for autumn wood and pine wood, in particular to a coating process for a European window production line. Background technique [0002] At present, outdoor environmental protection water-based paints are launched in the market, and the market share is increasing day by day, but the process is simplified, the cost can be reduced, and the production efficiency is rarely improved. Medium-quality pine and autumn wood are common door and window materials, but medium-quality pine and autumn wood are materials that are prone to fluff and tendons. It is difficult to paint and process. Now the price of paint is too high. The only way to solve the problem of wood itself is processing or Material selection, waste and high cost, is not a good way for enterprises to produce. Contents of the invention [0003] Aiming at the deficiencies of the existing technology, the technical problem to be solved by the present inventio...
