What are the types of wood mold inhibitors and what are the treatment methods for wood mold preventi

There are many classifications of wood fungal inhibitors, which are generally classified by phenols (such as phenol), chlorophenols (such as pentachlorophenol), organic mercury salts (such as phenylmercury oleate), organic copper salts (such as 8-hydroxyquinoline copper), organic tin salts (such as triethylene chloride or tributyltin chloride, etc.), and inorganic salts such as copper sulfate, mercuric chloride, sodium fluoride, etc.

How to check the mold resistance of wood mold inhibitors?

Test method for mildew resistance of wood.

Wood is being treated with mildew, but it is not possible to observe whether it is effective in a short time, so how to test the mildew resistance of wood? In fact, there is a test standard for wood mildew resistance.

JC T2039-2010 "Antibacterial and Anti-mildew Wood Decorative Board" is a recommended industry standard, which was first issued by the Ministry of Industry and Information Technology of the People's Republic of China and was implemented on March 1, 2011. The standard stipulates the terms and definitions, testing methods and inspection rules of antibacterial and mildew-proof wood decorative boards; Among them, the requirements for antibacterial performance and experimental methods refer to the Japanese National Industrial Standard JISZ2801-2000 "Antibacterial Processed Products - Experimental Methods and Antibacterial Effects of Antibacterial". The standard is applicable to wooden decorative panels for construction with antibacterial and mildew prevention functions, including all kinds of flooring and veneered wood-based panels; Other materials can be used as a reference.

Wood Mold Inspection Instructions.

Tested strains: Aspergillus niger (, Aspergillus terinarius, Penicillium wansonii (), Penicillium rope (), Bud brevis (, Bulbous conchotomys) (.

Wood mildew resistance rating.

Grade 0: Not long, i.e. no growth is visible to the naked eye.

Grade 1: Trace growth, i.e., visible growth with the naked eye, but the growth coverage area is less than 10% of the total area of the experimental sample; Grade 2: Slight growth, the colony of the mold spreads intermittently or loosely distributed on the surface of the substrate, and the mold growth accounts for less than 30% of the total area;

Grade 3: Moderate growth, mold growth and multiplication in large quantities, accounting for less than 70% of the total area; Grade 4: Severe growth, mold growth and multiplication, accounting for more than 70% of the total area.

Antibacterial and mildew resistant wood decorative panels.

The fresh wood must be mildew-proof, otherwise the spring and summer two to three moldy chun wood camphor wood is more easy to mold, redwood wood is less than the situation of red wood fungus 1. Fresh wood content: water, water in a specific environment, water evaporation, self-evaporation, resulting in wood shrinkage, cracking, bending, deformation, mildew and other defects seriously affecting the quality of wood products, wood must be forced (controlled) before all kinds of wood products are made, and the drying treatment must be carried out to overcome the defects of the wood, improve the strength of wood, and improve the processing performance of wood II. Drying wood in a humid environment is easy to mold, and dried wood needs to be treated with antifungal agents.

The wood itself is nutritious, and bai is a mold-prone material, which does not have an independent moisture-proof and mildew-proof function; Wood DAO wood is easy to absorb moisture and moisturize the version, especially for storage environmental rights.

In the case of moisture; Wood itself carries a lot of mold, such as poor storage environment, and there is no lack of mold spores. So it's very easy to get moldy.

Wood mildew prevention method:

1. Storage: The storage environment should be relatively dry to avoid rain. Try not to put it outdoors and don't pile it on dirt, otherwise mold will soon appear.

2. Anti-mildew treatment (in addition to the storage environment needs to be relatively dry, anti-mildew treatment is also required).

Method 1: If the plate needs to be fumigated, an antifungal agent can be added to the fumigation liquid;

Method 2: If there is a soaking process, you can add an anti-mildew agent to the soaking liquid, and the wood will have a good anti-mildew effect after soaking.

Method 3: If there is no other treatment, you can spray the wood surface directly with an anti-mold agent to carry out anti-mold treatment.

The wood itself can not be moisture-proof and mildew-proof, wood fibers will be absorbed when exposed to water, and mold will grow after sufficient moisture.

Deep carbonized wood, ecological wood, plastic wood composites.

High density can be, such as green sandalwood, purple sandalwood, and some corrosion-resistant such as fir wood, but generally use treated antiseptic wood.

Wood that has been soaked in a special wood antifungal agent.

1.Drying: This method can solve most of the problems, and the wood used in China can be used for this purpose, but it will not work for special uses such as sealed packaging, high humidity in the warehouse, and hot and humid conditions at sea when exporting.

2.Fumigation: This method is mainly for the export of wood packaging for insecticide, and the validity period is relatively short. Many friends mistakenly think that it is mildew prevention, but in fact, it has no effect on mold prevention and control at all.

3.Heat treatment: It is necessary to have special equipment, and the treatment cost is high, which can reduce the moisture content of the wood, but it cannot solve the fundamental problem.

4.Anti-mildew: The use of professional MEIBOSS wood anti-mildew powder treatment, you can use rapid soaking or brushing, etc., which is both convenient and cost-saving (generally mixed with water in a proportion) "Dry wood is still mildew if it is not mildew-proof, and the wood after mildew prevention has a good mildew prevention effect even if it is wet".

MEIBOSS wood anti-mildew powder is combined with fibers, which can be bonded to the surface of the product, and then use its strong anti-mold ability to effectively interfere with and destroy the physiological and metabolic activities related to microbial cells, and eventually lead to the growth and reproduction of microorganisms being inhibited until death. So as to protect all kinds of light chemical products and raw materials from mildew permanently and keep them intact.

All fresh wood must be mold-proof, otherwise it will become moldy in 2-3 days in spring and summer. Generally, Tsubaki camphor wood is more prone to mold, and mahogany has less mold.

1. Fresh wood contains a lot of water, and the water will continue to evaporate in a specific environment. The natural evaporation of water will lead to defects such as shrinkage, cracking, bending and deformation, mildew, etc., which will seriously affect the quality of wood products, so wood must be forced (controlled) drying before being made into various types of wood products. Correct drying treatment can overcome the above-mentioned wood defects, improve the mechanical strength of wood, and improve the processing performance of wood.

2. The dried wood is still easy to grow mildew in a humid environment, and the dried wood also needs to be treated with antifungal agents.

In our country, there are generally more antifungal agents for rubber wood and pine.
