The Usage of SINOMAC Wood Impregnation Autoclave

The vacuum pressure leaching process is widely used in the world for the treatment of wood preservative, degreasing, dyeing and so on. This process is the most important and effective way of industrial treatment for wood preservation. It will put wood in a special sealed pressure container tank, and put the antiseptic agent into the wood inside under pressure, and at the same time, heat treatment. It realized the physical process of introducing preservatives into wood, and completed the chemical reaction process of some effective components of preservatives and starch, cellulose and sugar in wood, and destroyed the survival environment of bacteria and insects that caused wood decay. SINOMAC wood impregnating autoclave series products can achieve fully automatic operation, perfect connection with production line, safe and efficient, and impregnation effect is superior to other similar equipments, energy saving, environmental protection and no pollution.

SINOMAC Wood Carbonization Autoclave

With the improvement of people's quality of life and environmental protection, we questioned the safety of using chemicals to treat wood and formulated some restrictive regulations for its use. The pure physical modified wood products are getting more and more extensive market space, and the deep carbonization technology of wood occupies an important position. Based on the careful study of the existing high temperature heat treatment equipment abroad and the improvement of domestic technology, SINOMAC has pioneered the development of Wood Carbonization autoclave and processing technology in China, which is the ideal processing equipment and technology for deep carbonization wood.

Advantages of SINOMAC TPC Software
SINOMAC Wood autoclave is equipped with advanced TPC control system. This system is developed on base of researching many control systems at home and abroad for many years. It has been very mature and popular. The system has basic functions as below: login permission, sensor options, technology curve setting/calling/saving/printing, automatic/manual performance, real-time data monitoring/record/saving/printing, parts conditions monitoring, alarm, quality analysis, report forms, etc.

● Control system Option: PLC+HIM or PLC+PC

Vaccum/High pressure immersion treatment process

1.Full cell process

A. Initial vacuum   B. Adding preservatives   C. Pressurization  D. Pressure soaking  E. Depressurization、recoil F. Discharge preservatives   G. Final vacuum   H. Restore the atmosphere

Characteristics of the full cell process
When the soaking tank is turned into a vacuum, a part of the air in the wood is also extracted. The resistance of the preservative into the wood is relatively small. With pressure, the preservative is easier to enter the wood, so the preservative is filled with wood cells. There are many antiseptic doses, which may retain the maximum number of preservatives.

2. Empty cell process

Characteristics of the empty cell process
The initial air pressure instead of the initial vacuum forced the air into the wood cells and compressed, and the antiseptic of the pressure when exposed to pressure was more than the full cell method. The maximum penetration depth is reached by the minimum amount of absorption, and the drug is saved and the cost is reduced. Full cell process has a large number of chemicals present in the cell cavity, and empty cell method cell cavity is empty or contains only a small amount.

Hundreds of wood rot fungi in the world have eroded all kinds of wood in use, causing the decay of wood. The decay of wood often presents the use value of the wood, such as the crack, the fiber, the sieve, and so on. More than 200 soft rot fungi make soft applications of common wood that are soaked in water for a long time and are exposed to soil for a long time, resulting in loss of use value. Sugar in wood fiber can also attract bacteria to rot wood and rot. At the same time, the organic substances such as hemicellulose and lignin in wood also provide a good environment for insects to be eroded. Therefore, wood preservative treatment plays a vital role in improving the service life of wood. If handled well, it will not decay for a long time. The wooden structure buildings left over for thousands of years in ancient China are proved.

◆ Wood autoclave is widely used in the fields of wood preservation, degreasing, flame retardancy, dyeing and so on

◆ Wood Carbonization autoclave is widely used in the field of wood carbonization. The pyrolytic process of wood is carried out through high temperature (160-230 C) for a long time. Carbonization is pure physical treatment technology without adding any chemicals, so it is an environmentally friendly anti-corrosion treatment method.
