How to brighten bamboo products? How to care for the elderly

There is a special brightener. The principle of action of the brightener is that it can quickly penetrate into the inside of the bamboo silk fiber through boiling. After boiling and then high-temperature carbonization, and then high-temperature hot pressing, the bamboo mat can be made bright in color and bright in lustre.

The treated bamboo silk can effectively improve the added value of its bamboo products (bamboo mats).

The anti-mildew treatment methods for bamboo products are as follows:

Improve storage conditions: Bamboo products should be stored in a ventilated and dry place, and should be equipped with ventilation and dehumidification equipment if conditions permit, so that the indoor relative humidity is lower than 75%.

Boiling bath: For small bamboo products, boiling bath treatment can be carried out at a temperature of more than 70. Boiling baths can effectively reduce the soluble nutrients that grow mold in bamboo and can destroy potential mold.

Bleaching: Bleaching treatment has the effect of eliminating latent mold, and can be bleached with 10% hydrogen peroxide, and the effect is good.

1. Oil soaking: soak in olive oil, vegetable or animal oil, which will not change color and not be easy to crack after soaking. Remember not to use industrial oils.

2. Hot oil coloring: put the dried bamboo into 200 hot oil, and the bamboo after taking it out is a glossy purple red, and the processing performance is good, which can be used as a handicraft material or a design blank for bamboo products.

3. Pressurized heating and coloring of non-combustible gas: first put the bamboo into the press, extract the air of the device, inject argon, helium and other inert gases, and then make any of the non-combustible gases such as sulfur dioxide, nitrogen, and carbon dioxide, or more than 2 kinds of mixed non-combustible gases, so that these gases account for more than 90 of the press. Then, heat the device to 100 150 degrees Celsius, and maintain the pressure for more than 30 minutes, you can make a purple-red bamboo with a shiny surface.

If the bamboo products are not suitable for a long time, they should be dried in a ventilated place until the hands can not touch the moisture on the surface of the bamboo products, and then seal and store them with tape.

June and July of each year is the rainy season, and there are many humid weather, so it is necessary to check the sealed bamboo products frequently, and clean them up in time if there is a long hair.

In case of good weather, take it out in time to dry, if it is a precious bamboo product as a collection, the preservation conditions are even more demanding. There are special safe deposit boxes, which have specific requirements for temperature and humidity.

There are four ways to care for the elderly:

First of all, for the cleaning of old bamboo, soapy water must be used to clean it, but do not wash it often, it will affect the aesthetics, if it must be cleaned, walnut oil can be added after cleaning, so that it is not easy to have insects.

Secondly, the old bamboo should be rolled with shelled raw walnuts with special protective oil, not fried walnut kernels. The oil sediment rolled out of the shelled walnut is less, and it contains a certain amount of moisture, which is not dry and does not hurt the bamboo. The oil and gas of cooked walnut kernel rolling are large, and after smearing and drying, the bamboo is easy to crack.

Then after that, the protective oil can not be much, and it is easy to get wet. At the same time, do not use various knives to repair the attachments on the pen holder, so as not to damage the original appearance and appearance of the old bamboo.

Finally: Collectors with conditions can put the old bamboo collection in a glass cover and seal it for preservation, which can ensure constant humidity. It can also be stored in a wooden lattice cabinet.

The temperature of the special safe cabinet is 20°C to 35°C, the relative humidity is 35% to 40%, the lower part of the cabinet is placed porcelain and other items, and the bamboo carvings are placed 1 meter above the ground. If the temperature is too dry and too high, you can put a bowl of water indoors or put a few books in the cabinet. The method of putting old newspapers can also be used, but the recirculation of newspapers is strong and should not be more.

It is necessary to play and check frequently, especially during the rainy season in June and July every year, and if you find moldy and long hair, you need to remove it with a bristle brush in time.

The biggest weakness of bamboo is that it is easy to mold, easy to crack, easy to attract insects, in the natural environment, can not be preserved for a long time, and there are few bamboo furniture handed down before the Ming Dynasty. Modern bamboo product manufacturers have conducted special research on bamboo insect prevention and mildew prevention. Some of these methods are simple and safe.

Here are a few examples.

Insect repellent liquid: zinc sulfate insect repellent liquid, take 9 5 kg of hydrochloric acid with a concentration of 0 5, 0 5 kg of zinc sulfate, 10 grams of resorcinol, prepare a solution, put the bamboo into the soak for 2 minutes and then take it out to dry.

Anti-mildew: Alum anti-mildew liquid, take a small amount of alum and put it in clean water to make a saturated solution. Put the bamboo utensils in and soak them for 2 minutes, then take them out and let them dry.

Demold: 5 grams of sodium peroxide, 95 mg of water, and a solution for mold; Hydrochloric acid with concentration 2 is solution B. Soak the moldy bamboo into the nail solution for about 1 to 10 minutes, depending on the severity of the situation, or use a brush dipped in nail liquid to brush off the mold.

Rinse with water, then soak in solution B, if there is no mildew in 15 minutes, rinse with water and dry. "Bamboo Records Tibetan Law" records: "The predecessors made so little today, the winner must be made of wood, between two or three years will be tung tung oil fine brush once, that is, with cotton cloth to dry, take its moist not dry.

In case of dry weather, do not play, and prevent damage and cracking. Its red color is as amber as above, goose oil is precious enough, and black is below. It can be seen that there is also knowledge in maintaining bamboo carving.

Bamboo carving handicrafts are most afraid of sun exposure, and should be stored in a cool, clean and humid environment. If you don't have time to play, you must put it away with a cloth cover or box, and avoid dust to prevent mold. The color of bamboo carvings is naturally formed by air oxidation and human hand friction.

This is also part of the natural charm of bamboo carving crafts. It is not advisable to apply color or to enhance oxidation with chemicals. Only commonly used hand play, relying on human hand rubbing can make the color of bamboo better.

Some people want to use methods such as oiling or lacquering to polish bamboo, which is also not good. Because the paint will soak into the nicks. Grease stains can damage the work.

Others want to make the ornamentation on the bamboo more clear, using color to fill in the nicks, but this "cheesy" practice will reduce the artistic taste of the bamboo carving, which is really enough to add to the painting.

Pay attention to the temperature and humidity of the air and the pH value of the environment.

1) Hot oil coloring: Put the dry bamboo into 200 hot oil, and the bamboo after taking out is a glossy purple red, and the processing performance is good, which can be used as a handicraft material or a design blank for bamboo products.

2) Pressurized heating and coloring of non-combustible gas: first, put the bamboo into the pressure vessel, extract the air in the container, inject argon, helium and other inert gases, and then make any one of the non-combustible gases such as sulfur dioxide, nitrogen, and carbon dioxide, or more than 2 kinds of mixed non-combustible gases, so that these gases account for more than 90 in the pressure vessel. Then, the container is heated to 100 150 and the pressure applied at the same time is maintained for more than 30 minutes to make bamboo with purple red inside and outside and shiny surface.

3) Carbonization coloring: The bamboo is soaked in polyhexyl alcohol (molecular weight 1500) solution and heated, the bamboo is brown-red, so that the bamboo is reduced to a minimum by adverse factors such as oxidation or cracking, and the bamboo is uniformly colored from the surface to the core, maintaining good processing performance and providing convenience for making handicrafts with higher value. The heating temperature of carbonization coloring is taken 60 200, and the heating time should be based on the degree of carbonization and coloring required, the purpose of use of bamboo, the immersion of bamboo in the treatment tank, etc., and make appropriate increases and decreases, this treatment part affects the mechanical processing performance of bamboo, non-toxic, and can maintain a long-term treatment effect.

4) Acid treatment coloring: The use of strong acid to chemically treat bamboo products can make bamboo products appear bronze. This treatment falls under the category of chemical staining.

The products made of bamboo strips and bamboo grains after this coloring treatment are antique and rich in national flavor. Specific operation: take 100kg of clean water, 1kg of sulfuric acid or nitric acid, prepare a solution in an acid-resistant container, immerse bamboo products such as bamboo strips or bamboo grains in the solution, pick it up after 10 15min, and then place it in a saturated lime aqueous solution for 30 40min, rinse it with water after taking it out, and use it after drying.

The color of the product can be controlled by adjusting the concentration of the calculation and the soaking time of the bamboo product.

If you want the bamboo paint to not fade, it must be treated with a special process. Bamboo process processing paint steps: 1) hot oil coloring: put the dried bamboo into 200 hot oil and take.

Healthy and environmentally friendly, some use tung oil or dama resin, and the surface wear resistance and hardness are high with alkyd or acrylic varnish.

What kind of paint is good for bamboo? I think we should use that kind of transparent paint, that is, it is very bright after oil, and you should be able to see the texture of the bamboo, so that the bamboo that comes out is particularly good, and the yellowing and white are the primary colors, which are very good-looking. In the past, that kind of tung oil was also possible.

If you use something else, he won't be able to produce his original color after that, so it's not good-looking.

It's best to find a professional painter to get it. If you want to do it yourself, first polish the surface of the bamboo directly with water sand, wipe it clean and apply a layer of clear primer (general one), after the clear primer is dry, and then polish it with water sand, you can rest assured that the white and blue paint can be used.

There are several ways to keep the bright green color of the bamboo after cutting:

1. Soak copper sulfate with water to keep it bright green.

2. Use copper ions (such as copper chlorophyll) to replace magnesium ions, so that it is not affected by oxidation, and the surface of bamboo can remain green.

3. Soak it in water, if you add some salt to the water, you can better preserve the chlorophyll and keep it green.

4. If the bamboo is not very long, it can be placed in the refrigerator, or placed in a sink, which can maintain the green time.

5. Wrap the incision with a water bag and a water storage block (for flower arrangement) to keep it green for a long time.

Just buy two boxes of green watercolor powder and paint it.

There are three points to pay attention to when bamboo products do not crack: First, buy bamboo products made of 8 to 10 years old bamboo, especially high-end bamboo art, which is the most critical. Second, apply natural resin to prevent cracking.

The third is maintenance. Bamboo products are afraid of drying, and if they are too dry, they are easy to crack, so we should pay attention to them in autumn and winter. 1. Drying and ventilation is the most important because of the particularity of bamboo furniture, so it should be placed in a dry place, if it is often placed in a humid and dark place, it will be beneficial to the reproduction of microorganisms due to humidity, and mildew is easy to occur.

For example, large bamboo utensils such as cabinets, bookshelves, and reclining chairs should be removed from the cracks, rinsed with water, and dried. Especially for bamboo utensils that are not used temporarily, they should be washed and dried, and then stored in a dry and ventilated place. 2. Make sufficient preparations in advance If you have the conditions, you can apply varnish and cooked tung oil when you just buy back bamboo furniture.

This is not only moth-proof, but also durable and beautiful, which is a good thing to kill multiple birds with one stone. Newly purchased small and medium-sized bamboo products such as baskets, mattresses and other products are best resteamed by high-temperature sealed steam. Steaming for 2-3 hours can completely kill the insects and microorganisms hidden in the bamboo.

You can also use boiling water and a certain amount of salt to soak the bamboo for 1-2 days, which can also prevent insect moth. If insects are found, the following methods can be used to remove insects: first, use an appropriate amount of sharp pepper or pepper, mash it into the end, stuff it into the moth hole, and flush it with boiling water, which has the effect of killing insects and can prevent the spread of insects; The second is to mix it with kerosene and a trace amount of dichlorvos, and drip it into the cavity, which can also kill the moth.

However, this method is not suitable for baskets, cabinets and other bamboo utensils to store food, in order to prevent accidental bamboo moth prevention and antiseptic treatment 1) The physical methods mainly include high temperature method, water immersion method, smoke method, modified atmosphere method, far infrared method, microwave method and ray method, and the advantages of these methods are pollution-free and five residual poisons. The disadvantage is that treated bamboo or bamboo products may be infected with borers and mold if they are not stored properly. In addition, bamboo felled in spring is susceptible to insect damage, and bamboo cut in winter is less susceptible to insect damage, so bamboo felling should be arranged in winter as much as possible.

Moreover, the cut bamboo should be transported to the production site as soon as possible for use, or treated with insect and moth prevention to reduce insect moth and mildew. 2) The chemical methods mainly include coating method, impregnation method, cooking method, fumigation method and pressure injection method. The advantage of these methods is that the anti-moth and anti-corrosion effect is good, and the time is long, and the disadvantage is that some agents are toxic and easy to pollute the products and the environment.

With the enhancement of people's awareness of environmental protection, the environmental protection requirements and standards for bamboo insecticides, preservatives and mildew inhibitors are getting higher and higher, such as Europe has banned the use of CCA, PCP and other preservatives, and mainly uses CCB, CCF, and ACQ and other preservatives.

Moths and termites are the most dangerous enemies of bamboo furniture. Because bamboo is rich in cellulose, hemicellulose, lignin and sugar, fat, protein, etc., these components are nutrients for insects such as borers and termites, so when using bamboo furniture, we should take certain measures to prevent insect moths to increase the service life of bamboo furniture.

First of all, when choosing bamboo furniture, it is best to choose one that has been coated with varnish or tung oil, which can not only prevent moths, but also be durable and full of beauty. If you buy small and medium-sized bamboo, it is best to treat it with high-temperature sealed steam to completely kill the bacteria in the bamboo, or put the bamboo in boiling water with table salt for a few days to prevent insect damage.

Secondly, in the use of bamboo furniture, commonly used bamboo baskets, rice baskets, rice baskets and other utensils should be brushed and dried in time, and large bamboo furniture should be placed in ventilation and drying. In addition, if you find that the insect is eaten in use, you can use a small amount of insecticide solution (dichlorvos) to drop into the insect moth hole, or you can use sharp pepper or Sichuan pepper to pound it into the end and stuff it into the insect moth hole, which can give your bamboo furniture a safe protection. However, it is important to remember that the above two sterilization methods cannot be used for tableware and bamboo utensils.
