Pa malonda a matabwa padziko lonse lapansi, Paulownia wood amagwiritsidwa ntchito kwambiri popanga mipando, kulongedza katundu, ndi kupanga zinthu zopangidwa ndi manja chifukwa cha kupepuka, chinyezi-chosamva, komanso{1}}zosavuta{2}kupanga zinthu. Ochita zamalonda akunja akuyenera kumvetsetsa kusiyana kumeneku kuti awonetsetse kuti kusankha kwawo zinthu kumakwaniritsa zosowa za kasitomala ndikuchepetsa kuopsa kwa malonda.
1. Kusiyana Kwachiyambi: Kusiyana Kwakukulu Pakati pa Chitchainizi ndi Zogulitsa Pamalo A Paulownia Wood
China ndi imodzi mwa mayiko omwe amapanga matabwa a Paulownia padziko lonse lapansi, ndipo Paulownia (Paulownia) wochokera ku Lankao, Henan, ndi Shaoyang, Hunan ndi wotchuka kwambiri. Mitengo yaku China ya Paulownia imadziwika ndi kupepuka kwake komanso kufewa kwake (kuchuluka kwake pafupifupi 0.25-0.4g/cm³), chimanga choyera, komanso kukana chinyezi, zomwe zimapangitsa kuti zikhale zoyenera kutumiza mipando ndi mapaketi. Mosiyana ndi zimenezi, mayiko ena akumwera chakum'mawa kwa Asia (monga Indonesia) ndi South America (monga Brazil) amatulutsanso mitundu yofulumira-yomwe imakula mofanana ndi paulownia, koma mitundu ya matabwayi imakhala ndi kachulukidwe kakang'ono (pafupifupi 0.4-0.6 g/cm³) ndipo imakhala yolimba, koma yosamva chinyezi. Amagwiritsidwa ntchito makamaka pomanga formwork kapena pallets zamakampani.
Makampani amalonda akunja akuyenera kuzindikira: mapanelo amitengo aku China paulownia, omwe amakwaniritsa miyezo yapadziko lonse lapansi (monga chiphaso cha FSC), amakondedwa kwambiri ndi misika yapamwamba-yomaliza ku Europe ndi ku America. Komabe, mitengo ina yotsika-yotsika mtengo ya paulownia yochokera kunja ikhoza kukumana ndi kuchedwetsedwa kwa chilolezo cha kasitomu chifukwa cha vuto la kukhala kwaokha.
2. Kuwerengera: Zinthu Zofunika Kwambiri Zomwe Zikukhudza Mtengo ndi Kugwiritsa Ntchito
Pazamalonda apadziko lonse lapansi, mapanelo amitengo ya paulownia nthawi zambiri amagawidwa m'makalasi atatu: A, B, ndi C, kutengera tirigu, chiwopsezo, komanso kuwongolera bwino:
• Mapanelo a matabwa a paulownia a Sitandade A: Opanda ming'alu ndi ming'alu, okhala ndi njere yofanana, ndi oyenera-pampani wapampando wapamwamba kwambiri ndi zida zoimbira (monga ma guitar soundboards). Amalamula mtengo wapamwamba wa kunja (pafupifupi 400-600 RMB pa kiyubiki mita). • Mitengo ya Grade B Paulownia: Zofooka zazing'ono zimaloledwa ndipo zimagwiritsidwa ntchito ngati mipando, zitsulo, kapena zoikamo. Mtengo ndi wocheperako (250-400 / kiyubiki mita).
• Mtengo wa Paulownia wa Giredi C: Zopanda ungwiro zimaonekera ndipo umagwiritsidwa ntchito kwambiri popanga mapaleti akumafakitale kapena-zojambula zamanja zotsika. Mtengo ndi wotsika (150-250 / kiyubiki mita).
Ndibwino kuti makampani amalonda akunja atchule momveka bwino zomwe amafunikira m'makontrakitala awo ndikuphatikizanso miyezo yovomerezeka padziko lonse lapansi (monga malamulo a National Highway Traffic Safety Association (NHLA) kuti apewe kubwezeredwa chifukwa cha mikangano yabwino.
3. Chithandizo: Kusiyana Pakati pa Mng'anjo-Zouma ndi Zoteteza-Machiritso
Mtengo wa Paulownia ukhoza kuwonongeka chifukwa cha chinyezi chambiri. Ogula m'mayiko ena amafuna kuti ogulitsa azipereka nkhuni zouma-zouma (KD), zomwe zimafuna chinyezi cha 8%-12%. Mitengo ya Paulownia yotumizidwa kuchokera ku China nthawi zambiri imawotchedwa-youma pakatentha kwambiri, zomwe zimapangitsa kuti ikhale yoyenera kuyenda maulendo ataliatali{8}}panyanja. Komabe, ogulitsa ena aku Southeast Asia atha kungopereka nkhuni-zouma (AD), zomwe zimasinthasintha kusiyanasiyana kwa chinyezi (15%-25%) ndipo sachedwa kutupa m'malo achinyezi. Choncho, kusamala kumalangizidwa posankha. Kuonjezera apo, pa ntchito zakunja (monga mipando ya m'munda), malamulo ena apamwamba amafunikira mapanelo amatabwa a paulownia kuti alandire chithandizo cha anti-corrosion (monga ACQ kapena CCA impregnation). Mtundu uwu wa bolodi ndi 15% -20% okwera mtengo kuposa matabwa wamba zouma, koma zimawonjezera moyo wawo wautumiki.
4. Malangizo Othandiza Amalonda Akunja: Momwe Mungapewere Zowopsa mu Paulownia Wood Panel Transactions?
1. Fotokozani Miyezo Yazida: Pamene mukufunsa, funsani ogulitsa kuti apereke dzina lasayansi la nkhuni (monga Paulownia elongata) ndi umboni wa chiyambi** kuti mupewe chisokonezo pakati pa paulownia ndi mitengo ina yofewa yomwe imakula mofulumira{3}(monga poplar).
2. Amafuna Malipoti Oyesa: Amafuna kuti ogulitsa apereke ziphaso zoyezera chinyezi, mpweya wa formaldehyde (magiredi a E0/E1), ndi malipoti a heavy metal pamodzi ndi katunduyo kuti azitsatira malamulo a EU REACH kapena miyezo ya US CARB.
3. Konzani Njira Zoyendera: Mapanelo a matabwa a Paulownia ndi akulu koma opepuka. Ndibwino kuti muwonjezere kulongedza katundu mukamagwiritsa ntchito zochepa-kuposa-zodzaza zotengera (LCL) kuti mupewe kuwonongeka m'mphepete ndi m'makona a thiransipoti zomwe zingapangitse kuti mtengowo ukhale wotsika.
Mapeto
Ngakhale mapanelo a matabwa a Paulownia ndi chinthu chodziwika bwino pamalonda, kusiyana kwawo kwamtundu kumakhudza kwambiri mpikisano wamsika wazinthu zomaliza. Pokhapokha pomvetsetsa bwino kusiyana kwakukulu monga chiyambi, kalasi, ndi njira zogwirira ntchito zomwe makampani ochita malonda akunja angagwirizane bwino ndi zosowa za makasitomala ndikukulitsa malire a phindu. Ndibwino kuti mukhazikitse laibulale yachitsanzo yokhala ndi{2}}opereka zinthu kwanthawi yayitali ndikuchita cheke ndi maubwino amagulu ndi -mabungwe ena owunika (monga SGS) kuti muwonetsetse kuti pali mayendedwe okhazikika komanso odalirika.
