1. Liphapang tsa Tšimoloho: Phapang ea Sehloho lipakeng tsa Machaena le Lehong la Paulownia Wood
China ke e 'ngoe ea bahlahisi ba kholo ka ho fetisisa lefatšeng ba patsi ea Paulownia, ha Paulownia (Paulownia) ho tsoa Lankao, Henan, le Shaoyang, Hunan e tsebahala haholo. Chinese Paulownia wood e khetholloa ka bobebe le bonolo ba eona (botenya bo ka bang 0.25-0.4g/cm³), lijo-thollo tse hlakileng, le ho thibela mongobo oa tlhaho, ho etsa hore e tšoanelehe bakeng sa thepa ea ka tlung le ho paka. Ka lehlakoreng le leng, linaha tse ling tsa Asia Boroa-bochabela (joalo ka Indonesia) le Amerika Boroa (joaloka Brazil) le tsona li hlahisa mefuta e ntseng e hola ka potlako-e ts'oanang le paulownia, empa mefuta ena ea patsi e na le boima bo phahameng (hoo e ka bang 0.4-0.6 g/cm³) 'me e khona ho mamella, empa e sa khone ho mamella mongobo. Haholo-holo li sebelisoa bakeng sa ho haha formwork kapa li-pallets tsa indasteri.
Likhamphani tsa khoebo tsa kantle ho naha li lokela ho ela hloko: Liphanele tsa China tsa paulownia wood, tse fihlelang maemo a machaba a tikoloho (joalo ka setifikeiti sa FSC), li ratoa haholo ke limmaraka tse phahameng- tsa Europe le Amerika.

Ka hona, ho eletsoa ho ba hlokolosi ha ho khethoa. Ho feta moo, bakeng sa ts'ebeliso ea kantle (joalo ka thepa ea jareteng), litaelo tse ling tsa maemo a holimo li hloka hore liphanele tsa paulownia li fumane kalafo e khahlanong le kutu (joalo ka ACQ kapa CCA impregnation). Boto ea mofuta ona ke 15% -20% e theko e boima ho feta mapolanka a tloaelehileng a omisitsoeng, empa e eketsa bophelo ba bona ba tšebeletso haholo.
