How bamboo can achieve the effect of aging

In a tank under pressure, soak in copper sulfate solution for 2-3h, then soak at atmospheric pressure for 12h and then dry.

Use a small amount of initiator, molecular weight 500-1000, soak in a pressure tank for 1h, atmospheric pressure for 4h, and then place it under 40-50 for 12h to make the monomer completely polymerized.

Using Polystat K-133, copper naphthenate, copper sulfate and other chemicals and strong microwave action for 3min, the green fastness, durability and weather resistance of bamboo have been greatly improved.

Due to the particularity of bamboo, the color treatment will make the product more artistic. Bamboo dyeing includes hot oil dyeing, non-gas pressure heating coloring, carbonization dyeing, and acid treatment coloring.

Hot oil dyeing. Put the dried bamboo into 200 meters of hot oil, the bamboo is purple-red, shiny, and has good processing performance. It can be used as a raw material for handicrafts or a design blank for bamboo products.

Extended Information: Bamboo Dyeing Methods:

1. Non-combustible gas is pressurized and heated and colored.

The bamboo is placed in a pressure vessel, the air in the container is pumped out, and inert gases such as argon and helium are injected. After that, any one or more non-combustible gases such as sulfur dioxide, nitrogen, carbon dioxide and so on can be mixed to make these gases account for more than 90% of the pressure vessel. Then heat the container to 100 150, and apply the pressure for more than 30min, you can make purple inside and outside, smooth surface bamboo.

2. Carbonization and coloring.

Soaking the bamboo in a polyhexanol solution and heating it gives the bamboo a brownish-red color, which minimizes the impact of adverse factors such as oxidation or cracking. Moreover, the color of bamboo is uniform from the surface to the core, and it maintains good processing performance, which provides convenience for making handicrafts with higher value.

The heating temperature of carbonization coloring is 60 200, and the heating time should be increased or decreased according to the carbonization, coloring degree, purpose of bamboo use, and bamboo soaking in the treatment pool. This treatment part affects the mechanical processing performance of bamboo, which is non-toxic and can maintain the treatment effect for a long time.

3. Chromic acid treatment.

Bamboo products are chemically treated with strong acids to make bamboo products appear bronze. This treatment falls under the category of chemical staining. The products made of bamboo strips and bamboo grains through this dyeing process are antique and full of ethnic flavor.

Take 100kg of water, 1kg of sulfuric acid or nitric acid, prepare the solution in an acid-resistant container, immerse the bamboo strips or bamboo particles in the solution, take it out after 10-15min, put it in the saturated lime solution for 30-40min, rinse it with water after taking it out, and dry it. By adjusting the concentration and soaking time of bamboo products, the color depth of the product can be controlled.

Wow, this one is a little complicated, you have to dry the beads first, you must dry them very dry, because there is moisture in the original bamboo, and then you have to roast them on the fire, evaporate the fish water, and continue to heat them, which will make the bamboo brown and yellow, let it stand, and repeat it in a few days, it will be about the same in about a month, and then the pillars will be pruned again, and you will be fine, I wish you success.

This is a technical job, and the technical level must be at home, otherwise it will not be effective.

First, you can modulate the color to bring out the color you need.

Second, it should be processed by baking technology to make retro colors.

Third, hand polishing should also account for a certain proportion.

I've seen this in the south, and it's beautiful.

This is easy to do, first use the bamboo with white paint as the base, and then use the varnish to add color essence red, yellow and black to spray, absolutely convenient speed!

Soak it in the lake to allow it to corrode, and after leaving it for some time, it is scooped up and exposed to the sun. This will look a bit old and old-fashioned.

Hello, I'm glad to answer you for the answer, you can go through the color modulation, tune out the color you need. It can also be treated with the baking and nahoring technique, soaked in 15% sodium benzoate solution for 1 hour, and then soaked in salt to absorb water and then dried.
