Title: Drying


1
Drying
  • Wood drying should be used seasoning for
    decreasing moisture content in wood lesser than
    30 for 1 month, then drying with kiln drying
    for 1 month.
  • Lumber should be control drying at surface, not
    rapidity dried.
  • If moisture content in wood and surface of wood
    are difference more than 5 , wood stress due to
    wood failure, e.g. bow, case hardening, and
    honeycombing.

2
Drying
  • But some wood failure occurred from natural
    property of wood, e.g. grain and age,
  • that fast growing species such as Eucalyptus and
    SaDuaTium, due to stress in wood, emphasize high
    growth stress of young tree.
  • That is easily the end split.
  • Therefore, the end of lumber should be printcoat
    for decreased evaporate moisture from wood.
  • In addition to, piling should be used stick at
    the end of lumber and pressed on the top by
    weight.

III. Processing and Utilization
  • 1. Primary processing
  • 1.1 Sawing
  • 1.2 Wood preservation
  • 2. Secondary processing
  • 2.1 Furniture manufacturing
  • 2.2 Wood-based panels manufacturing
  • 2.3 Pulp and paper manufacturing
  • 2.4 Charcoal production

4
Furniture
  • 1) Stable furniture or Furnished furniture
  • 2) Knock down furniture
  • 1) Usage skilled labor more than unskilled labor
  • 2) Manufacturing by machine
  • 3) Manufacturing by machine more than skilled
    labor

5
Wood-based panels
  • - Veneer and plywood
  • - Composite board
  • - Fiberboard
  • - Particleboard
  • - Wood cement board

6
Veneer and plywood
  • The shortage of large log, due to some factory
    changed peeling machine from 8 ft. to 4 ft.
    length and slicing machine for the thinnest
    veneer, 0.1 mm. thickness.
  • Some factory imported log for veneer production
    and re-export or overlay on wood products of
    factory.

7
Composite board
  • Flooring (parquet and mosaic parquet) and block
    board are common technology.
  • by finger joint technique.
  • Raw materials are Teak and Eucalyptus from
    plantation, rejected wood in flooring production
    20-25 and 50-60 , respectively.
  • Colour coating need to production because of
    still sapwood (cream colour), that difference
    from heartwood (dark colour).

8
Fiberboard
  • Hardboard and Medium Density Fiberboard (MDF).
  • All of Hardboard in Thailand produce with wet
    process.
  • Raw materials of Hardboard are Eucalyptus and
    wood from plantation e.g. KraTinTaPa (Acacia sp.)
    and also Bagasse.
  • Raw materials of MDF are Rubberwood, Eucalyptus,
    KraTinTaPa, and Bagasse (MDF, which Bagasse used
    the first factory of the world).

9
Particleboard
  • Particleboard used as raw material for
    construction and furniture production because of
    decreasing of solid wood and logging ban in 1989.
    Due to particleboard used increasing in wood
    working.
  • Extruded pressed processing used only one
    factory. Another factory used platen pressed
    processing.
  • Raw materials are Rubberwood, Eucalyptus and
    Bagasse. 3 layers sheet, 12 and 16 mm. thickness,
    is characteristically of particleboard in
    Thailand.

10
Wood cement board
  • Raw material of Wood Wool Cement Board is
    SomPhong (Tetrameles nudiflora R.Br.), import
    from Myanmar, today.

Wood Cement Particleboard produced from
Eucalyptus.
Wood Cement Fiberboard, plank for wall house,
produced from cement approximately 90 and
recovered paper approximately 10 with mixed a
little asbestos.
11
Pulp and paper
  • Raw materials non-wood (e.g. Straw, Bamboo,
    Kenaf and Bagasse) and wood (Eucalyptus).
  • That is short fiber, so Thailand must imported
    long fiber and also recovered paper.

12
  • All pulp factories produce with chemical process
    except one factory produced pulp with
    semichemical process yield approximately 45 .
  • The products are kraft paper 50 and other
    papers printing-writing paper, paperboard,
    newsprint paper, household and sanitary paper etc.

13
Charcoal
  • Its produced with soil or rice husk mound and
    mud beehive.
  • Commercial charcoal produced usually with brick
    beehive.

Now, lapwood of Eucalyptus from plantation
widespread produced charcoal and briquett for
export. In addition to, activated carbon produced
from charcoal for industry.
14
  • Each year, Thailand has consumption charcoal 3
    million kg. Demand of charcoal for export is
    large scale.
  • Recovery rate of charcoal production is 30-35
    of wood at oven dry weight.
  • Pile of Eucalyptus 1 cu.m. can be produced
    charcoal 120 kg. Heat value of Eucalyptus
    charcoal is 7.35 kg.cal/g.
  • The highest heat value is charcoal from KongKang
    (Rhizophora sp.), 7.50 kg.cal./g.

15
IV. Markets and Socio-Economics
  • Wood consumption in Thailand is about 3-4 million
    cu.m./year.
  • Imported wood and wood products (1999)
  • 1. Log 0.47 million cu.m. cost 80.8 million and
    sawntimber 1.25 million cu.m. cost 169.9
    million.
  • 2. Wood productions plywood, particleboard,
    fiberboard, parquet, fuelwood, charcoal,
    furniture, door, window, etc total cost 28.9
    million.
  • 3. Pulp 438,525 tons of total cost 177.5
    million.
  • 4. Paper 365,208 tons of total cost 362.8
    million.

16
IV. Markets and Socio-Economics
  • The averaged increasing of Thailands population
    is 1.2 per year. In 1985, Thailand has 53
    million populations and increased to 61 million
    in 1999,
  • therefore, the demand in wood and wood products
    consumption increased every year.
  • The countrys capacity to produce and reforest
    cannot meet the demand so the price of wood and
    wood products still high.

30
1. Forestry Act
  • The Forestry Act 1941 for protect the selection
    cutting and illegal logging. The mentioned law
    did not support to the present wood industry
    development.
  • The act improvement is quite difficult and more
    complex, thus the promulgated the new act is the
    success way, for example The Forest Plantation
    Act 1992

31
2. National Forest Policy
  • Created in 1983 for the long term in forest
    resources management and development were
    concerned about this issue
  • - government organization, private and community
    sector
  • - wood industry
  • - reforestation, plantation
  • - etc

32
3. Thai Forestry Sector Master Plan
  • formulated during 1990-1993 by the technical
    assistant of the Finland government.
  • for solving the problem of the short of wood and
    strengthen the confidence on the raw materials by
    the management of forest plantation, community
    forest and private forest. (within 2010)

33
4. Funding support
  • from the Agriculture and Cooperatives Bank and
    the Japan Oversea Economic Cooperative Funding
    (OECF)
  • but the rules and conditions is complex
  • In conclusion, the funding which the farmer
    received was only 3,000 baht/rai from the Farmer
    Extension for Forest Plantation Project.

34
5. The composed cooperatives
  • For the forest plantation farmer to compose and
    set the cooperatives in each province.
  • The targets of the cooperatives are for log
    selling and wood industries for producing to
    support domestic demand and export.
  • There are 30 cooperatives, at present (Thailand
    has 76 provinces).

35
6. Reformation in the Industrial Structure
  • The Ministry of Industry hold a meeting to
    discuss for the new structure of Thailand
    industry
  • For the problems and create the strategies on
    Thailands wood products and furniture industry

36
7. Tariff measurement
  • The tariff measurement appointed the tax of
    exported log and lumber 40 , and 10 for the
    unsuitable wood for wood production.
  • The imported wood products can be locally
    produced is 20 and 10 of them which cannot
    locally produced.

37

  • 1) forest conservation and protection plan
  • 2) forest resource processing and utilization
    plan
  • 3) sustainable forestry management plan
  • Wood utilization program is appointed for the
    purpose of developing new efficient technology
    for local wood sp. instead of imported wood.

40

  • FPRD is directly responsible to study to
    products
  • - properties of wood,
  • - wood products,
  • - wood and non-wood industry,
  • - non-wood utilization,
  • - other materials instead of wood,
  • - energy from wood or residual agriculture.

44
VII. Overview and Conclusion
  • THAILAND
  • area 51,311,502 hectares
  • population 61.7 million.
  • Forest area 12,972,200 hectares (25.28 )
  • to increase forest lands to 40
  • wood consumption is 0.2 cu.m./year/person or
    12.34 million cu.m./year.
  • logging ban in 1989,
  • imported wood and wood products over than 800
    million.

45
VII. Overview and Conclusion
  • Wood shortage is still a major problem for
    related industries.
  • At present, there is an attempt to develop
  • Rubberwood species for timber,
  • high yield of fiber from Eucalyptus, including to
    add more value for wood from plantation to
    furniture and flooring industries.
  • Teak from thinning period is found to be too
    small and low recovery rate

46
VII. Overview and Conclusion
  • Thailand has a privilege for plantation due to
    its location.
  • Only 4-6 years for fast growing species and 30-40
    years for normal trees, harvesting can be done

47
Model of Wood Utilization
  • The best way to use a tree is to consider how to
    efficiently use every part of the tree such as
    root, stump, log and branches, which
    manufacturing process has to be employed. Wood
    may be dried and preserved to make it strong and
    last longer time.
  • Lapwood can be used for tools, wood products,
    parquet, woodfuel, charcoal and chipwood. Stumps
    and branches can be used as woodfuel and
    chipwood, as well, for large scale of industries
    of wood chemical products, pulp and paper,
    fiberboard, which made from chipwood through
    defibration process. Chipwood, also can be
    dissolved into particle, without defibrator,
    mixed with resin and cement for particleboard and
    wood cement board, respectively.
  • Timber can be added for highest value by using as
    veneer or plywood. Core and lapwood from the
    veneer process can be used as chipwood. Moreover
    some parts of wood from the process can be raw
    material for carving as well. Small log can be
    used as poles for construction.
  • As mentioned above, the uses of wood will be
    efficient and intelligent if there are industries
    to support or so called Integrated Wood
    Industries.

48
Model of Wood Utilization
49
VII. Overview and Conclusion
  • Due to economic crisis in Thailand, last 5 years
    there was decreasing of wood and wood products.
  • On the other hand export of such was increasing.
  • This may be results from industrial and economic
    reform.

50
VII. Overview and Conclusion
  • At present,
  • there is a concept to encourage local people to
    live on their feet.
  • The attitudes of using local products or their
    household products are arising.
  • The government has also launched a campaign
    namely One village, one product to promote
    indigenous knowledge to create their own specific
    product.

51
VII. Overview and Conclusion
  • For International Role on wood industry,
  • Thailand has joined the Commission on Sustainable
    Development (CSD) to pursue sustainable wood
    industries and make an agreement done on February
    1997 in New York,
  • following the proposal of Open-ended adhoc
    Intergovernmental Panel on Forests (IPF) to
    conduct sustainable forest management for wood
    industry in all aspect
  • business, environment, products and services from
    the forest.
