Kurhwebo lwehlabathi lwamaplanga, i-Paulownia wood isetyenziswa kakhulu kwimveliso yefanitshala, ukupakisha imathiriyeli, kunye nemveliso yezandla ngenxa yobunzima bayo, ukufuma-ukuxhathisa, kwaye kulula{1}}ukwenza{2}}ipropathi zepropathi.Nangona kunjalo, i-Paulownia wood esuka kwimvelaphi eyahlukeneyo ibonisa umahluko omkhulu kumgangatho wezinto eziphathekayo, ukusebenza, kunye nezicelo. Abasebenzi borhwebo bangaphandle kufuneka baqonde lo mahluko ukuze baqinisekise ukuba ukhetho lwabo lwezinto eziphathekayo luyahlangabezana neemfuno zabathengi kunye nokunciphisa imingcipheko yorhwebo.
1. Umahluko weMvelaphi: Umahluko oPhambili phakathi kweTshayina kunye ne-Paulownia Wood ethathwe ngaphandle
I-China lelinye lawona mazwe avelisa amaplanga e-Paulownia, kunye noPaulownia (Paulownia) osuka eLankao, eHenan, naseShaoyang, eHunan edume kakhulu. Umthi waseTshayina we-Paulownia uphawuleka ngokukhaphukhaphu kunye nokuthamba kwawo (ubunzima obumalunga ne-0.25-}0.4g/cm³), ingqolowa ecacileyo, kunye nokumelana nokufuma kwendalo, iyenza ilungele ukuthunyelwa kwefenitshala kunye nokupakishwa. Ngokwahlukileyo koko, amanye amazwe akuMzantsi-mpuma we-Asia (afana ne-Indonesia) kunye noMzantsi Melika (afana ne-Brazil) nawo avelisa iintlobo ezikhawulezayo-ezikhula ngokufana ne-paulownia, kodwa ezi ntlobo zemithi zinoxinano oluphezulu (malunga ne-0.4-0.6 g/cm³) kwaye ziyanyamezela, kodwa zikwazi ukumelana nokufuma. Ngokuqhelekileyo zisetyenziselwa ukwakha i-formwork okanye i-industrial pallets.
Iinkampani zorhwebo zangaphandle kufuneka zithathele ingqalelo: iiphaneli zeplanga zaseTshayina zepaulownia, ezihlangabezana nemigangatho yokusingqongileyo yamazwe ngamazwe (ezifana nesiqinisekiso seFSC), zithandwa kakhulu ziimarike{0}}eziphezulu zaseYurophu nezaseMelika. Nangona kunjalo, ezinye{2}ixabiso eliphantsi lemithi ye-paulownia ethengwa kumazwe angaphandle ingajongana nokulibaziseka kwemvume yesithethe ngenxa yemiba yokuvalelwa.
2. Ukuhlelwa: Imiba ePhambili echaphazela ixabiso kunye nokusetyenziswa
Kurhwebo lwamazwe ngamazwe, iiphaneli zeplanga ze-paulownia zihlelwa ngokubanzi zibe ngamabanga amathathu: A, B, kunye no-C, ngokusekwe kukutya okuziinkozo, umlinganiselo wesiphene, kunye nokuchaneka kokulungiswa:
• Iipaneli zomthi ze-paulownia zeBanga A: Ezingenamibhobho yobhobhozo kunye neentanda, ezinenkozo efanayo, zifanele iiphaneli zefenitshala{0}}eziphakamileyo kunye nezincedisi zezixhobo zomculo (ezifana neebhodi zegitare). Bayalela ixabiso eliphezulu lokuthumela ngaphandle (malunga ne-400-600 RMB nge-cubic meter). • I-Paulownia wood yeBanga B: Iziphene ezincinci ziyanyanyezelwa kwaye ziqhele ukusetyenziselwa ukuxhasa impahla yefenitshala, i-lining, okanye ukupakisha. Ixabiso liphakathi (250-400 / cubic meter).
• I-Paulownia wood yeBanga C: Ukungafezeki kuyabonakala kwaye isetyenziswa kakhulu kwiipalethi zemizi-mveliso okanye{0}}umsebenzi wezandla ophantsi. Ixabiso liphantsi (150-250 / cubic meter).
Kuyacetyiswa ukuba iinkampani zorhwebo zangaphandle zicacise ngokucacileyo iimfuno zebakala kwiikhontrakthi zazo kwaye zibandakanye imigangatho yokuhlelwa kwamaplanga eyaziwa kumazwe ngamazwe (efana nemithetho yeNational Highway Traffic Safety Association (NHLA) ukuphepha imbuyekezo ngenxa yeengxabano zobulunga.
3. Unyango: Umahluko phakathi kweKiln{1}}Eyomileyo kunye nePreservative-Unyango
I-Paulownia wood ichaphazeleka kwi-deformation ngenxa yobuninzi bayo bokufuma. Abathengi bamazwe ngamazwe badla ngokufuna ukuba ababoneleli babonelele ngeenkuni-zomisiweyo (KD) ngomthi wokufuma okujoliswe kuko yi-8%-12%. I-Paulownia wood ethunyelwa ngaphandle isuka e-China ikholisa ukuvuthwa{6}}yomisiwe kumaqondo obushushu aphezulu, iyenze ilungele ukuthuthwa komgama{8} wolwandle. Nangona kunjalo, abanye ababoneleli baseMazantsi mpuma e-Asia banokunika kuphela umoya{13}}owomileyo (AD) iinkuni, ezinoluhlu olubanzi lokuguquguquka kwesiqulatho sokufuma (15%-}25%) kwaye kulula ukudumba kwindawo ezifumileyo. Ngoko ke, kucetyiswa ukuba ulumke xa ukhetha. Ukongeza, ukusetyenziswa kwangaphandle (okufana nefenitshala yegadi), ezinye ii-odolo eziphezulu zifuna iipaneli zokhuni ze-paulownia ukuba zenze unyango oluchasene ne-corrosion (njenge-ACQ okanye i-CCA impregnation). Olu hlobo lwebhodi luyi-15% -20% ebiza kakhulu kuneebhodi eziqhelekileyo ezomileyo, kodwa kwandisa kakhulu ubomi babo benkonzo.
4. Iingcebiso eziSebenzayo zoRhwebo lwangaphandle: Indlela yokuphepha iingozi kwi-Paulownia Wood Panel Transactions?
1. Cacisa iMigangatho yezinto: Ngexesha lophando, kufuneka abathengisi banike igama lesayensi lenkuni (umzekelo, Paulownia elongata) kunye nobungqina bemvelaphi ** ukunqanda ukubhideka phakathi kwepaulownia kunye nezinye{3}}iiplanga ezikhawulezayo ezikhula (ezifana nepoplar).
2. Funa iiNgxelo zoVavanyo: Funa ababoneleli ukuba banike izatifikethi zovavanyo lomswakama, ukukhutshwa kwe-formaldehyde (amabakala e-E0 / E1), kunye neengxelo zomxholo wensimbi enzima kunye neempahla zokuthobela imimiselo ye-EU REACH okanye imigangatho ye-US CARB.
3. Lungiselela iindlela zoThutho: Iiphaneli zokhuni ze-Paulownia zikhulu kodwa zikhaphukhaphu. Kuyacetyiswa ukuba kuqiniswe ukupakishwa xa usebenzisa ngaphantsi-kune{3}}imithwalo yesikhongozeli (LCL) ukuthintela umonakalo kwincam neekona ngexesha lothutho olunokukhokelela ekuthotyweni kwamabango.
Ukuqukumbela
Ngelixa iiphaneli zomthi ze-Paulownia ziyimpahla yorhwebo eqhelekileyo, umahluko womgangatho wabo uchaphazela ngokuthe ngqo ukhuphiswano lwentengiso yemveliso yokugqibela. Kuphela ngokuqonda ngokucokisekileyo iyantlukwano engundoqo efana nemvelaphi, ibakala, kunye nobuchule bokuqhuba apho iinkampani zorhwebo zangaphandle zinokungqamanisa ngokuchanekileyo iimfuno zabathengi kwaye zandise imida yenzuzo yokuodola. Kuyacetyiswa ukuseka isampula yethala leencwadi elinababoneleli bexesha elide{2}} kwaye kujongwe umgangatho webhetshi kunye -nee-arhente zokuhlola zeqela lesithathu (ezifana ne-SGS) ukuqinisekisa isixokelelwano sobonelelo esizinzileyo nesithembekileyo.
