Wood decorative material biological enzyme pretreatment method

Abstract

Disclosed is a pretreatment method of biological enzymes for wood decoration materials, which is characterized by: first planing the wood; then scouring the wood planing, and adding 1 to 4% of biological enzymes relative to the weight of the wood planing into the scouring liquid; Scouring conditions: bath ratio 1:10-15, temperature 85-100°C, time 45-90 minutes, and finally washing with water. Effect: It solves the huge demand for interior wood decoration materials, and can plant cheap fast-growing trees in desertification areas or some barren mountains, wild lands, roadsides, etc. to increase farmers' income and reduce the felling of ancient and famous trees. It can effectively remove pectin, wax, ash, natural pigments, etc. in wood, so that the water absorption of wood and the color yield and uniformity of dyeing can be significantly improved, saving water, electricity, steam and chemical agents, reducing sewage discharge, and shortening production process, improve product quality, reduce production costs, reduce environmental pollution, and have very beneficial social and economic benefits.

Description

Technical field:

[0001] The invention relates to wood processing technology, which is a method for pre-treating wood with biological enzymes, in particular, a process for scouring and pre-bleaching wood decoration materials with chemical substances such as biological enzymes. Background technique:

[0002] With the increasing development of my country's national economy, the construction scale of urban residential areas and various office buildings is also increasing, which requires a large amount of interior wood decoration materials. Due to the long growth period of natural ancient and famous trees, the natural existence is less and less, it is difficult to regenerate, and there are more or less flaws, so it is difficult to meet people's needs. Although there are a large number of fast-growing trees such as poplars (white birch) that can be planted in a large amount in barren hills, wild lands, and roadsides, etc., or natural woods such as cheap fast-growing trees such as ...

Embodiment 1

[0008] Cooking process

[0009] For some medium-color products, it is necessary to remove the pectin substances in the wood that affect the dyeing, and add a biological enzyme that can remove pectin to the working solution. Biological enzymes are selected from Singapore Yum Clean Cotton Enzyme GX1 or Shanghai Cleaner 100T. The specific process is as follows:

[0010] Wood flakes → scouring [Yum Enzyme GX1 1-2% (relative to the weight of wood flakes), liquor ratio about 1:10, temperature 85-100°C, time 40-60 minutes] → water washing.

[0012] Cooking process

[0013] For some medium-color products, it is necessary to remove the pectin substances in the wood that affect the dyeing, and add a biological enzyme that can remove pectin to the working solution. The specific process is as follows:

[0014] Wood shavings → scouring [100T cotton cleaner 1-2% (relative to the weight of wood shavings), the bath ratio is about 1:10, the temperature is 85-100°C, and the time is 40-60 minutes] → washing.

[0016] Cooking process

[0017] For dark-colored products, it is also necessary to remove pectin substances in wood that affect dyeing, and add biological enzymes that can remove pectin into the working solution. The specific process is as follows:

[0018] Wood flakes → scouring [Yum Enzyme GX1 3-4% (relative to the weight of wood flakes), bath ratio about 1:10, temperature 85-100°C, time 40-60 minutes] → water washing.
