Abstract

The invention discloses a low-damage veneer bleaching formula and process. The low-damage veneer bleaching formula is prepared from 10% of diethylenetriaminepenta(methylene phosphonic acid) heptasodium salt, 2% of sodium polyacrylate, 5% of sodium hydroxide, 3% of a penetrant, 25% of hydrogen peroxide and 55% of water. The bleaching capacity of a bleaching agent at room temperature is very low, the bleaching capacity is different when needed temperatures are different, through the design of heating plates, liquid medicine is heated, the wood veneer bleaching efficiency needs to be improved, and meanwhile, the heating and constant-temperature effects are achieved in cooperation with the use of a temperature sensor and a temperature control instrument.

Description

technical field [0001] The invention relates to the technical field of veneer production, in particular to a low-damage veneer bleaching formula and a bleaching process. Background technique [0002] With its beautiful and generous natural patterns and unique texture, wooden products make people feel close to nature and return to nature. However, the reality is that the quantity of high-quality wood is small and the price is high, which makes it difficult to meet market demand. People make very thin veneer from high-quality wood with ornamental value, and stick the veneer on the wooden surface made of ordinary wood to make it have a high-quality appearance. The bleaching of veneer is an important link in the industrial processing of veneer. The bleaching of veneer is to decolorize the chromophoric group or auxochromic group and the components related to coloring through oxidation, reduction and degradation of bleaching agent. Purpose. [0003] Bleaching of veneer is an im...
