Abstract

The invention relates to a high-temperature cooking process for producing decorative boards by using fast-growing poplar wood. When the boards are cooked at high temperature, the sprayed saturated water vapor is changed into a liquid mixture of water (H2O) and sodium bicarbonate (NaHCO3) which are stirred evenly and sprayed into a baking furnace by a spraying machine to cook the boards at high temperature, wherein the ratio of the water (H2O) to the sodium bicarbonate (NaHCO3) is 95%: 5%. The process effectively improves the texture of the boards, fundamentally overcomes the distortion or deformation of the boards, reliably ensures product quality, improves productivity, reduces reject rate, and has considerable socio-economic benefits.

Description

technical field

[0001] The invention relates to a process for producing decorative boards with fast-growing poplar, in particular to a high-temperature cooking process for producing decorative boards with fast-growing poplar. Background technique

[0002] China CN1226117C (announcement date: November 9, 2005) "Method for producing flame-retardant and moisture-proof decorative boards with fast-growing poplar" adopts high-temperature cooking, slow dehumidification, dehumidification and drying, coating and natural drying to produce fast-growing poplar Wooden decorative panels, but there is a phenomenon that the panels are twisted or deformed. After research and testing, it was found that the occurrence of this phenomenon was due to the saturated water vapor sprayed into the oven during high-temperature cooking, which caused the fiber cells of fast-growing poplar to fully expand and loosen the texture. Contents of the invention

[0003] Aiming at the defects of the above-ment...

Examples

Embodiment Construction

[0006] The present invention continues to use the feeding, spraying and cooking process of high-temperature cooking in the "Method for Producing Flame-Retardant and Moisture-proof Decorative Plates with Fast-growing Poplar" in China CN1226117C (announcement date: November 9, 2005). And the dosage percentage is water (H 2 O): Sodium bicarbonate (NaHCO 3 )=95%: After the 5% mixed solution is stirred evenly, it is sprayed into a baking furnace by a jet machine to carry out high-temperature cooking of the plates. The furnace temperature is 80°C-90°C, and the cooking time is 78h-82h.
