Wood surface varnishing technology

Abstract

The invention discloses a wood surface varnishing technology. The wood surface varnishing technology comprises the following steps of: firstly scraping dust, oil stains, spots, glue marks and the likeon the wood surface by using a scraping knife, clearing burrs on the wood surface, and polishing the wood surface along wood grains by using above-No.1 abrasive paper till the wood surface is smooth;mixing and stirring big white powder, rosin water, boiled tung oil and the like to form color oil meal, dipping cotton staple in the oil meal, repeatedly applying the oil meal to the wood surface, and polishing the wood surface along the wood grains by using No.1 abrasive paper after the oil meal is dried completely; preparing putty by using gypsum powder, the boiled tung oil, water and the like,then adding pigment to form oil color putty, and polishing the wood surface along the wood grains by using the No.1 abrasive paper after the oil color putty is dried completely; mixing lead oil / or ready mixed paint, gasoline, gloss oil, clean oil and the like, sieving with a bamboo basket with a square bottom and a round mouth, and brushing along the wood grains; and varnishing three times undernormal conditions, wherein the varnishing method is the same as the method of brushing the oil color. Varnish can be more evenly brushed on the wood surface according to the wood surface varnishing technology; and the wood surface varnishing technology avoids the conditions that the varnish falls off, and the varnish brushing is uneven.

Description

technical field [0001] The invention belongs to the field of construction wood treatment, and in particular relates to a wood surface painting varnish process. Background technique [0002] Wood can be divided into two categories: coniferous trees and broad-leaved trees. Chinese fir and various pine, spruce and fir are coniferous trees, oak, ash, camphor, sassafras and various birch, nanmu and poplar, etc. It is a broad-leaved tree; therefore, the wood species commonly used in engineering in different regions are also different. Usually, in construction, wood is cut or combined into specific structures as doors and windows, etc., because it is necessary to ensure that the wood maintains sufficient corrosion resistance during use, so The wood needs to be painted, and the traditional painting method causes the paint to fall off due to its unreasonable steps, resulting in corrosion of the wood. Contents of the invention [0003] The purpose of the present invention is to pro...
