Description
Technical field
The invention belongs to Masson pine timber Anti- tarnishing technical field, and in particular to a kind of Anti- tarnishing processing of plate of Pinus massoniana
Method.
Background technology
One of the key character of color as material, is the important factor for determining material impression, and furniture and indoor dress
Most lively in repairing, the most active factor, while the still important indicator of poor lumber-trade value, to glued board, veneer, furniture
And decoration woodwork discoloration and go mouldy restricted, the discoloration of biological material is complicated physical and chemical process, is a variety of
The result of factor effect, Discoloration is different, and Discoloration mechanism is different, and the corresponding means of defence that changes colour is also different, in existing research
In understand, the climatic factor and environmental condition for causing sapstain are mainly：Microbial action, solar radiation, chemical reagent are made
Changed with, temperature and humidity, the presence of phenol, phenolase and oxygen is the necessary condition of enzymatic browning, and moisture content and humidity are enzyme discolorations
Important factor in order, discoloration of the timber during storage, transport, processing and use, mainly mould, bacterium discoloration and photooxidation become
Color, wherein, Masson pine timber is rich in carbohydrate, protein and trace element, it is easy to change colour, the plank after discoloration without
Method is faded again, has a strong impact on the use of Masson pine timber, therefore, for how to prevent sapstain from being ground in the application
Study carefully.
The content of the invention
The purpose of the present invention is to be directed to the problem of existing, there is provided a kind of Anti- tarnishing processing method of plate of Pinus massoniana.
The present invention is achieved by the following technical solutions：A kind of Anti- tarnishing processing method of plate of Pinus massoniana, the horse
Tail loose veneer is one kind in red blank material, full blank material, is comprised the following steps：
（1）Plate of Pinus massoniana is put into sealable treatment box body, layering tiling plate of Pinus massoniana, is passed through acid vapor, until
After acid vapor is full of processing casing, seal case processing 10-15 minutes, wherein salpeter solution concentration is 2.2-2.8N；
（2）Plate of Pinus massoniana after above-mentioned processing is put into boiling 1-2 hours in the urea liquid that mass concentration is 35-45%, steamed
