1. Melemo eaPlywood ea China
1.1.Plywood e ntle haholo ea Softwood e nang le Lifahleho tse Khabisitsoeng tsa Hardwood Veneer
China e ipabola ka ho etsa plywood ea boleng bo holimo e nang le mapolanka a thata a khabisitsoeng. Mefuta e tummeng ea veneer e sebelisetsoang ponahalo ea botle e kenyelletsa poplar, birch, elm, maple le oak. Lifate tsena tse thata tse teteaneng ka mokhoa o itekanetseng li fana ka moetso o khahlang le lipaterone tsa mebala e sa tšoaneng. Theknoloji e tsoetseng pele ea ho hatella le ho khomarela e etsa hore ho be le maqhama a matla a lamination le ho bata ho phahameng plywood e felileng. Li-glue extenders li boetse li eketsoa ho ntlafatsa ho hanyetsa mongobo. Libaka tse boreleli li fokotsa boiteko bo eketsehileng ba ho sebetsa bo hlokahalang pele ho ts'ebetso ea ho qetela.
1.2.Litšenyehelo tse tlase ka lebaka la Thepa ea Lehae le ho Reka Patsi e tala e Thekoang
Bongata ba lifate tsa popoliri tse tsoang masimong a ka leboea bo thusa ho theola litšenyehelo bakeng sa likarolo tsa mantlha tsa plywood. Ho feta moo, likutu tsa phaene tsa radiata tse tsoang linaheng tse ling tse tsoang New Zealand le eucalyptus tse ntseng li hōla ka potlako tse tsoang merung e ka boroa li tlatsetsa thepa e ngata. Methapo ea tlhahiso e tsoetseng pele ea ho ebola, ho khaola le ho seha ho ntlafatsa chai le ho fokotsa tšenyo ea li-veneers tsa lehong le thata. Ho etsa lintho ka boiketsetso le hona ho ntlafatsa tlhahiso ea basebetsi. Ka hona, litšenyehelo tsa thepa le tsa ho sokoloha li tlholisano haholo bakeng sa plywood ea China.
1.3.Phepelo e Felletseng ka Mechini, Likutu, Lik'hemik'hale, jj.
China e thehile ketane ea phepelo ea indasteri ea plywood ka har'a naha. Ho ba teng ha selehae ha mechini ea bohlokoa ea tlhahiso ea plywood joalo ka lithapo tse ebolang, lithapo tsa ho khaola, liomisa le mechine ea khatiso e chesang e qoba ho itšetleha ka thepa e tsoang kantle ho naha. Ntle le moo, likarolo tse tšehetsang tse kang sekhomaretsi, lik'hemik'hale tse koahelang, lisebelisoa le likarolo tse ling kaofela li ka fumaneha sebakeng sa heno. Kopanyo e joalo boemong ba indasteri e hlahisa katleho.
1.4.Sekala se Seholo se nang le Basebetsi ba Khethehileng ba fetang limilione tse 1
Tekanyo e kholo ea indasteri e theha letamo le tebileng la talenta le ho bokella tsebo ea mahlale. Ho hakanngoa hore basebetsi ba fetang milione e le 'ngoe ba Chaena ba sebetsa ka thata ho tsamaisa thepa ea plywood. Basebetsi ba kenyelletsa litsebi tsa lifeme, baenjiniere ba lisebelisoa, bo-rasaense ba lepolanka, baqapi ba lihlahisoa joalo-joalo Sena se fana ka motheo bakeng sa baetsi ba Machaena ho qapa le ho ipabola likarolong tse itseng tsa plywood. Palo e kholo ea tlhahiso e boetse e ntlafatsa ts'ebetso ea litšenyehelo.
2. Mabaka a Ka morao ho Litšenyehelo tse Tlaase
2.1.Semela se seholo sa Poplar se Fana ka Li-Core Veneers tse theko e tlaase
Poplar ke mofuta oa lehong o ntseng o hola ka potlako o lengoang masimong a ka leboea ho China. E na le boima bo tlase le 'mala o mosoeu. Ka meru e lengoang e inehetseng bakeng sa tlhahiso ea plywood, lifate tsa poplar li ka fumanoa ka litšenyehelo tse tlaase haholo ho etsa li-core layer veneers. Mekhoa e mecha ea ho ebola e eketsang chai ea veneer ho tloha poplar e nyenyane ea bophara ba eona e thusa ho fokotsa litšenyehelo. Kahoo lisebelisoa tsa temo ea popoliri li bohlokoa ho nolofalletsa plywood ea theko e tlase China.
2.2.Ho kenya Radiata Pine ho tsoa New Zealand ka Litheko tse ntle haholo
Radiata pine ke mefuta ea softwood e tsoang New Zealand e 'nileng ea sebelisoa haholo ho plywood ea meralo. Ka phepelo e ngata le likamano tse tsitsitseng tse hahiloeng ho theosa le lilemo lipakeng tsa indasteri ea meru ea China le New Zealand, li-sawlog tsa radiata pine li ka rekoa kantle ho naha ka litheko tse phahameng haholo. Lisebelisoa tsa masimong tse laoloang ka mokhoa o tsitsitseng hammoho le litšenyehelo tse ntle tsa ho tsamaisa thepa li etsa hore thepa ea phaene ea radiata e be theko e tlase bakeng sa tshilo ya China ya plywood.
2.3.Plantation Eucalyptus e tsoang South China Hape e Fumaneha
Lifate tsa eucalyptus tse ntseng li hola ka potlako li lengoa masimong a Guangdong, Guangxi le liprofinseng tse ling tse ka boroa ho China. Kotulo ea selemo le selemo ea lifate tsa eucalyptus e fihla mashome a limilione a cubic metres selemo le selemo. E le mohloli oali-veneers tse khabisitsoeng, mapolanka ana a lenngoeng lehong le thata a ka fumanoa hamonate ka litheko tse ntle ke baetsi ba lehae ba plywood. Kahoo ho tlatselletsa lisebelisoa tsa tlholisano tsa plywood.
3. Mefuta ea Lifate tsa Key Wood tse tsoang Chaena
3.1.Poplar - Sefate sa ho Lema se Holang ka Potlako se Sebelisitsoeng Bakeng sa Mekhahlelo ea Bohareng
Joalo ka ha ho boletsoe pejana, poplar (P. deltoides kapa P. ussuriensis) ke sefate sa temo se holang ka potlako naheng ea China. Haholo-holo li lengoa masimong a mahlahahlaha libakeng tse ka leboea, li ka kotuloa ka chenchana e khutšoane ho hlahisa likutu tsa 'mala o mosehla tsa boima bo fokolang. Mapolanka a joalo a poplar a loketse ka ho feletseng bakeng sa ho etsa liphahlo tsa plywood core layer veneers ka lebaka la ho tšoana, ho sebetsa le melemo e theko e tlaase.
3.2.Radiata Pine - E tlisitsoe New Zealand bakeng sa Mehaho ea Mehaho
Radiata pine (Pinus radiata) e tlisitsoe kantle ho naha ho tsoa New Zealand lilemong tse mashome tsa morao tjena ho leka-lekanya khaello ea phepelo ea mapolanka a lehae China. Ka phepelo e ka tšeptjoang le litheko tse utloahalang tsa ho kenya, radiata pine e phetha karolo ea bohlokoa ea ho sebetsa e le likarolo tsa mohaho oa tlhahiso ea plywood, ho tlatsetsa larch, fir le lisebelisoa tsa spruce.
3.3.Eucalyptus - Mofuta oa lehong le thata bakeng sa Mekhabiso e ka Holimo-limo
Eucalyptus (E. urophylla, E. grandis, E. pellita) ke mefuta e meholo ea temo ea patsi e thata e lengoang ka boroa ho China. Eucalyptus e fana ka mebala e monate, sebopeho le boima ba holim'a metsi ka theko ea moruo, e loketseng ho hlahisa li-veneers tsa sefahleho le tsa morao bakeng sa plywood e khabisitsoeng. Ho fumaneha ha bona ka bongata ho matlafatsa lefapha lohle la tlhahiso ea plywood.
4. Boitsebiso bo Eketsehileng bakeng sa Bahoebi
Baetsi ba Pele ba Plywood China e na le barekisi ba bangata ba nang le bokhoni ba ho etsa li-plywood tseo ba ka khethang ho tsona. Likhoebo tse ling tse kholo li kenyelletsa Happy Wood, Kemian Wood, Shandong Shengda Wood le Guangxi Fenglin Wood. Likhamphani tsena li shebana le lihlahisoa tsa plywood tsa boemo bo holimo tse netefalitsoeng ke CARB, CE, FSC le litekanyetso tse ling tsa lefats'e.
Taolo ea Boleng le Mekhoa ea Teko Baetsi ba Machaena ba tsoetseng pele ba kenya tšebetsong litsamaiso tse thata tsa taolo ea boleng nakong ea tlhahiso. Ba beha leihlo li-parameter tse kang veneer grading, glue spread rate, khatello ea khatiso le mocheso joalo-joalo.
Ts'ebetso ea Tlhahiso le Tsamaiso ea Fektheri Mechini e sebetsa ka mehala ea sejoale-joale ea tlhahiso libakeng tsa lithupelo tse koetsoeng tse hloekileng, tse thusoang ke othomathike. Mehaho ea bona e netefalitsoe ke ISO kapa e sebeletsa ho fumana kananelo e joalo. Lisebelisoa tsa khase ea litšila, masalla le metsi a litšila li kentsoe bakeng sa ho latela tikoloho. Limela tse ling li boetse li sebelisa masala a lehong bakeng sa ho fehla matla a biomass.
Nako ea ho etella pele, Mekhoa ea ho Romela le Likhetho tsa Tefo
Bakeng sa litaelo tsa plywood tse tsoang kantle ho naha, nako e tloaelehileng ea ho etella pele e ka ba matsatsi a 30-45 ho tloha ho netefatso ho isa ho palamiso boema-kepeng ba China. Mekhoa ea ho romella e kenyelletsa thepa ea leoatleng ea 20ft le 40ft. Litefiso tse bolokehileng tse kantle ho marang-rang li kenyelletsa phetisetso ea mohala, PayPal, lengolo la mokitlane jj.
