The analysis of treatability is based on the speed absorption of preservative. This experimental comes with an important role to experience particularly for the impregnation of timbers inside the vacuum pressure process or the double vacuum process. Rely upon particular real wood, the treatment guidelines are picked to ensure the real wood receives the best possible protection from the process. The standard additive treatment is at grouping of seven, which is important to treat timber in order to know the ingestion range of every. The treatability grouping of Standard Additive Treatment comes in the table below:
Greater than 320 kg/m3
Below 30 kg/m3
To know the rule of the previously mentioned evaluation of timber treatability at a laboratory scale. To find out just how treatability is definitely affected by unadulterated water by temperature 100°C for 60 minutes.
Kapur, or perhaps Dryobalanops spp. The timber is a channel hardwood in the range denseness of 580-820 kg/m3. Kapur have a very substantial percentage of shrinkage.
The shrinkage of a lot of species happen to be summarised beneath:

Meranti, or Shorea spp. This kind of timber is known as a light hard wood with a array of density among 595-755 kg/m3. Different with Kapur, Meranti have an normal percentage of shrinkage. Chengal, or Neobalanocarpus hemii. This timber have higher thickness than Meranti and Kapur which in the product range of 915-980 kg/m3. Shrinking is fairly low, with gigantic shrinkage hitting 1 . 1% and tangential shrinkage averaging 2 . 6%
The elements and the tools used in the experiment will be drying range, veneer calliper, beakers, normal water bath, unadulterated water, and wood trials. The drying oven is used to remove normal water from the solid wood sample simply by drying the wood examples within a day at 103°C. Next is a function of veneer calliper is to measure the length, size, and elevation of the wood samples. From your measurement of wood trials we get the dimension of wood de. The wooden samples is put in the beaker when it did start to process of frosty soaking of wood cubes. The an additional function of beaker is utilized to place the samples in the water bathroom during warm soaking procedure. Water bath is set up in the experiment within 100°C regarding 60 minutes. It can be used during hot soaking process. Throughout the hot putting and chilly soaking the water used is a distilled water. The distilled water can be used because it does not have pollutants particles that disturb the end result. The wooden samples via three various kinds of wood which are kapur, meranti, and chengal. Each species we take away three types of wood de. The dimensions of real wood samples is similar as 2cm x 2cm x 2cm. The wood samples happen to be labelled. Every woods test was crushed stone with 320 grit fine sand paper and above to reduce dust and splinters. Simply defect totally free, smooth and clear anisotrophic samples was selected.
Prior to begin the experiment, 3 samples of wood from 3 different types was chosen. The varieties were Kapur, Cengal and Meranti with dimensions of two cm times 2 centimeter x 2 cm. The wood varieties was determined with identical dimensions and everything the real wood samples was sand of with 320 grit of sand paperwork to get rid of the dust and splinters. The selected wood sample is then...
