Tiyeni tiwone ubwino ndi kuipa kwa mitundu yodziwika bwino ya boardboard substrate pamsika:

Tiyeni tiwone ubwino ndi kuipa kwa mitundu yodziwika bwino yamagulu amsika pamsika:

1. Eukalyptus: Mtengo wopepuka wa masamba otambalala okhala ndi njere zowundikika, zosakhazikika.Sapwood wosanjikiza ndi wotakata, woyera mpaka wotumbululuka pinki;Heartwood ndi yofiira kwambiri.Eucalyptus ndi nkhuni zomwe zimakula mofulumira, osati zolimba, zopepuka, zosavuta kuthyoka.Eucalyptus amalimidwa kwambiri kumwera ndi pakati pa United States ndi dera la Guangxi ku China, ndipo amagwiritsidwa ntchito kwambiri popanga makabati ndi mipando, makamaka mipando yakale.

Ubwino: Mtengo wa Eucalyptus ndi wovuta, kuchuluka kwa zinthu zomalizidwa, kugwiritsitsa mwamphamvu, dzimbiri zosavala, zosavuta kupindika kapena kuwononga zabwino, ndi imodzi mwazinthu zabwino kwambiri zopangira mipando yamatabwa, yopangidwa ndi mipando yokhala ndi katundu wabwino. mphamvu, osati zosavuta deformation.Kuonjezera apo, kununkhira kwa mafuta a bulugamu kumapangitsa kuti anthu azikhala omasuka komanso omizidwa muzochitika zoyenda m'nkhalango.

2. Pine: ndi mtundu wa chomera cha coniferous (zomera zodziwika bwino ndi paini, fir, cypress), zokhala ndi kununkhira kwa pine, mtundu wachikasu wopepuka.

Argentina PINE: COLOR SLANTS YEELLOW, KUKHALA KWAMBIRI NDIKULU, KUKHALA KWAMBIRI, NSOMBA NDI ZOSAVUTA ZIKUONEKA KWAMBIRI.

Brazilian pine: mtundu wachikasu wopepuka, wokonda zolemba, wapakatikati mwa mphamvu zamakina.

New Zealand PINE (RADIATA pine) : Mtundu wowala wachikasu, mawonekedwe owongoka, pepala lopangidwa ndi kukhazikika kwapamwamba komanso mphamvu yopindika, kukana kwamphamvu komanso kusinthika kosavuta komanso mawonekedwe opindika.3. Manchuria manchuria: makamaka opangidwa kumpoto chakum'mawa ndi North China.Yellow yoyera kapena yofiirira pang'ono yachikasu, yosiyana koma mphete zosagwirizana, zamitengo

Kapangidwe kake ndi kowawa ndipo kuuma kwake ndi kwakukulu.

Ubwino: elasticity wabwino, kulimba, kuvala kukana, kukana chinyezi ndi makhalidwe ena;Kudula kosalala pamwamba, utoto, kumata kumatha kukhala kwabwino.

Zoipa: Zovuta kuuma, zosavuta kupindika.

4. Mitengo ya mphira: nkhuni za rabara ndi kupanga mkaka wa rabara wa chomera, ndi thunthu la mtengo wa rabara, mitundu ya mitengo ya subtropical.Mtengowo ukakalamba, thunthu lake likhoza kupangira mipando.Ndi chitukuko cha msika wa mipando, matabwa a mphira amagwiritsidwa ntchito kwambiri pamipando, pansi, matabwa, ndi zina zotero, mtundu wake ndi wofiirira wachikasu, mphete zikuwonekera, malire a gudumu ndi lamba wakuda, dzenje la chubu. ndi ochepa kwambiri, kapangidwe ka matabwa ndi kolimba komanso kofanana.

Ubwino: kupanga mkombero ndi wamfupi kuposa mitengo ina, ndipo zokolola ndi mkulu, chipika ndi wotchipa;Kulemera pang'ono, kuuma, mphamvu ndi kulimba, kosavuta kuuma, kuchita bwino kwa makina;

Zoipa: mphira sanunkhiza, chifukwa cha shuga, osavuta kutulutsa, kuwola ndi njenjete.Osawuma mophweka, osavala, kusweka kosavuta, kupindika kosavuta, kupindika kwa mbale.5. Mapulo: Pali mitundu iwiri ya mapulo ofewa ndi mapulo olimba.Kulimba kwa mapulo ofewa ndi pafupifupi 25% kutsika kuposa mapulo olimba.Wood AMASONYEZA phulusa bulawuni KUTI PHIRIRA phulusa, PANG'AL PAKATI SI ZOCHITIKA, TUBE HOLE NDI KWAMBIRI NDI zing'onozing'ono, KUGAWANA NDI NGAKHALE, M'CHIKHALIDWE NTCHITO PA PLANK MTIMA KUTI WOYERA PANSI.

Ubwino: kapangidwe kabwino komanso kofanana, kopepuka komanso kolimba, ntchito yabwino yopenta, kumamatira mwamphamvu.

Kuipa kwake: Malo odulidwawo si osalala, osavuta kupindika akauma.6. Birch: mphete yapachaka imakhala yowonekera pang'ono, mawonekedwe ake ndi owongoka komanso owoneka bwino, kapangidwe kazinthu kamakhala kosavuta komanso kofewa komanso kosalala, kapangidwe kake ndi kofewa kapena kocheperako, muzu ndi mfundo zake zimakhala ndi machitidwe ambiri, ndipo anthu akale ankagwiritsa ntchito. kuchita pachitseko pachitseko ndi zokongoletsa zina.

Ubwino: Kuchita bwino kwa makina, kudula kosalala, kupenta bwino komanso kugwira ntchito kwa gluing.

Zoipa: kusiyana kwa fiber shear, kosavuta "kusweka chiputu";Sichilimbana ndi kuvunda ndi kuvala.Ndiosavuta kusweka ndi kupindika mukaumitsa

7. Aspen: Mtundu wa mitengo yobala zipatso yomwe ikukula mofulumira, ilipo yobzalidwa kwambiri kumadera akummwera ndi kumpoto kwa dziko lathu, ndipo chuma cha aspen ndi cholemera.

Ubwino: ndi kusinthasintha lonse, nthawi yaitali pachaka kukula, mofulumira kupanga liwiro ndi makhalidwe ena, khalidwe lake lofewa, ntchito khola, wotchipa ndi zosavuta kupeza.

Zoipa: Chifukwa cha kapangidwe kake komanso zinthu zosafunikira, ulusi wa poplar umakhala wochepa pakugwiritsa ntchito kwake.Amagwiritsidwa ntchito kwambiri ngati matabwa olimba ophatikizika pansi, template yomanga, mbale yapansi, zinthu zazifupi zamafakitale kapena misewu ndi mitengo yamitengo yobiriwira.

Zomwe zimapangidwira zimatsimikizira ubwino, machitidwe a mitundu yosiyanasiyana ya mitengo ndi yosiyana, yomwe imatsimikizira kuti ikugwiritsidwa ntchito bwanji komanso momwe amagwiritsira ntchito mbale yomaliza.Kusamala mwatsatanetsatane, khalidwe ndi chitonthozo, chitetezo ndi thanzi, Australia, apamwamba a pine kunja, liam byrne, ku zopangira, AMAGWIRITSA NTCHITO apamwamba kunja paini, pambuyo peeling mankhwala zimatulutsa kuwala paini nkhuni, mulibe zosafunika kuwonongeka ndi zosangalatsa. fungo, kapangidwe ka yunifolomu, palibe kumenyana, kugwira mphamvu ya misomali ndikwabwino, kugwiritsa ntchito guluu wachilengedwe wa MDI, kuteteza chilengedwe.
