Sunken wood treatment: Newly bought sunken wood will generally be yellow.
But please rest assured that the yellow water released by the commonly used sunken wood (purple teak, driftwood, etc.) is not harmful to fish and shrimp, and can even adjust the water quality, so that the water hardness in the hard water area is reduced, and the water quality conditions are comfortable for fish to survive.
In the process of formation, due to the carbonization of sunken wood, it will naturally produce a number of colored derivatives, such as lignin.
Humic acid or tannin acid.
These pigmented substances are the reason why the water turns yellow after the sunken wood is put into the tank. Many people think that yellow water is not good-looking, but in fact, it is very simple to deal with.
1. Blister: Soak the whole sunken wood in a container, change the water twice a day, and last for about a week to significantly reduce the yellow water (the effect of soaking in the river and lake is more obvious).
2. Hot water soaking: it can accelerate humic acid and tannin acid.
extraction speed. Add hot water and cover, wait until the water temperature cools down, then change the hot water again, and repeat until the water is no longer yellow.
3. Boiling water: Although this method is fast, it is generally only suitable for small sunken wood, because it is really difficult to find a large container that can boil water. It is completely submerged in water, boiled for half an hour, and then taken out and soaked in cold water for a day. Do this for a few days!

A: Dehydration and coating with FRP coating will definitely make the wood soaked in water without yellowing.

Wood products soaked in water, water will be yellow, real pure natural wood products are faded, chemical dyeing and lacquered fakes will not fade. Due to the uneven distribution of resin in the wood, the shrinkage rate of the drying process is different, which will cause stress cracking, so the traditional processing method will soak the wood for more than several months before processing.
The art of Chinese wood carving can be traced back to the primitive society, when there were many handicrafts that began to take shape. By the Warring States Period, the wood carving process had been developed from the simple carving and carving of carved plates used in the pottery process in the Shang Dynasty to the three-dimensional round carving process. The Han Dynasty animal wood carving was made of whole wood carving, which pushed the art of Chinese wood carving to a peak.
Boxwood carving. Boxwood carving is named after the wood used for boxwood carving. As early as the beginning of this century, Zhu Zichang and others created excellent works such as "hide and seek", which won international awards at the Nanyang Industry Association and the Pacific International Panama Expo, making boxwood carving a sensation at home and abroad. In addition, boxwood is tough and smooth, delicate in texture, with ivory effect, and the age gets deeper and deeper, simple and beautiful.
The boxwood carving techniques are abundant, in addition to round carving, openwork carving, relief carving, but also created a variety of techniques such as inlay, which has a high degree of artistry. Boxwood carving is mainly used for art appreciation, so the carvers are very particular.

Mixture of hydrogen peroxide (30% concentration) and ammonia (25% concentration) (hydrogen peroxide:ammonia:water =:
1)。When operating, use a plant fiber brush (do not use a nylon brush, otherwise it will rot in a while) to moisten the surface of the wood with bleach, and after 15-30 minutes, the wood will turn white. When the surface meets the bleaching requirements, wipe the surface clean with a clean damp rag or wash the bleach solution with cold water to dry.
Hydrogen peroxide (30% concentration) and sodium hydroxide solution (1 kg of sodium hydroxide dissolved in 1 kg of water). During the operation, first wipe the wood surface with sodium hydroxide solution, after 15-30 minutes, then apply hydrogen peroxide, and then scrub the wood surface with clean water after treatment, and neutralize sodium hydroxide with weak acid (about acetic acid or oxalic acid) solution, and finally scrub it with clean water and dry it at room temperature.
The key to these operations is to test and understand the optimal concentration and process. Because different woods have different oil content and different permeability, they cannot be completely copied. Start with a few samples and then slowly expand them.

Answer: Hydrogen peroxide, also known as hydrogen peroxide, is a kind of bleach that is more widely used and has a better bleaching effect. The commonly used concentration is 15 30, it can release strong oxygen on the surface of the wood, decompose the pigment of the wood, make it white, in order to accelerate the release of oxygen, ammonia can be mixed with hydrogen peroxide, wet the surface of the wood with this bleach, after more than ten minutes, wash off the bleach with cold water. Ammonia should not be added too much, under normal circumstances, the amount of ammonia added to 25 is about 5 10 of hydrogen peroxide.

Wood in general absorbs water.
The color becomes darker after absorbing water.
However, the color returns to normal after drying.

Sandalwood is a kind of wood that changes color easily when exposed to water.

Mahogany becomes darker when washed with water.
Deep carbonized wood technology is to put the wood in a fully enclosed deep carbonization equipment without adding any chemicals, and at the same time ensure that there is no oxygen and no water, high temperature (175 °C-212 °C) high pressure, and the wood is improved for 48-60 hours, and the moisture content of the wood after deep carbonization is less than 8%, which is golden brown and has a slight charcoal scorching smell. >>>More
