autoclave for wood chemical treatments
autoclave for wood chemical treatments / chemical treatments for wood / autoclave for wood preservation
All measures that are taken to ensure a long life of wood fall under the definition wood preservation (timber treatment).
In moist and oxygenated soil, there are few treatments that enable vulnerable wood (softwood here) to resist for long against bacterial or fungal degradation
Apart from structural wood preservation measures, there are a number of different (chemical) preservatives and processes (also known as timber treatment, lumber treatment or pressure treatment) that can extend the life of wood, timber, wood structures or engineered wood. These generally increase the durability and resistance from being destroyed by insects or fungus. In order to ensure the durability of wood, it is necessary to subject it to chemical treatments in autoclave for treatment of wood.
2. Materials of ZG autoclave for wood preservation :
A) Q345R-GB713 of Hangang in Hebei.
B) 16MnII level of making flange forging
C) φ 133× 25 tube to make DN100 and the material is 20-GB9948.
3. Process:
A) After welding the door, it must be proceed annealing heat treatment.
B) Polish toothed cutter of flange of autoclave body, and carry out magnetic particle testing.
C) Use double scale container board, and ensure the longitudinal joint of each section.
D) Carry out the physical and chemical test (stretch, impact), ensure its strength.
E) Welds are 100% X-ray detection, then carry out hydraulic test of 2.1MPa after passing. The whole process is complete inspected by CSEI factory inspection, and leave factory after stamp and signature. http://www.zgautoclave.com/zgnews/Wood-treating-autoclave-manufacture-in-Thailand.html http://www.zgautoclave.com/product/Autoclave-for-Wood-treatments.html
