Za MDF, MFC, ndiWPC
Pakufufuza kwathu kwatsiku ndi tsiku, abwenzi ambiri amafunsa kuti MDF ndi MFC ndi chiyani, komanso ubale pakati pawo.
Kodi pali kusiyana kotani?
1. Mwachidule, MDF ndi MDF, ndiko kuti, MDF-Medium Density
Fiberboard)
MFC ndi melaminefacedchipboard, yomwe ndi mtundu wa particleboard.
Monga zinthu zoyambira, pamwamba pake amakonzedwa mwapadera ndi MELAMINE, yomwe imakhala yosavala, yosayamba kukanda komanso yosagwira.
Gulu lokongoletsera lamagulu ndi ubwino wa kutentha kwakukulu, kuyeretsa kosavuta, asidi ndi kukana kwa alkali, ndi zina zotero, zomwe zimafupikitsidwa monga MFC (melamine veneer) mu Chingerezi.
MFC imagwiritsidwa ntchito kwambiri ngati zida zazikulu zopangira mipando, mipando yamaofesi ndi mipando yakukhitchini.
Kulumikizana pakati pa MDF ndi MFC ndikuti MDF ndiye maziko ndipo MFC ndiye maziko.Monga nsalu ndi utoto,
Nsalu ya mwana wosabadwayo imakhala yopanda mtundu, ndipo imatha kukhala ndi mitundu yosiyanasiyana komanso ntchito zina pambuyo poupaka utoto ndi kumaliza.
Melamine ikhoza kuphimba magawo osiyanasiyana, monga particleboard, MDF, bolodi lapamwamba kwambiri ndi zina zotero.Magawo osiyanasiyana
Mtengo udzakhala wosiyana, ndipo particleboard ndiyotsika mtengo kwambiri.
Wopangidwa ndi sing'anga (wamkulu) kachulukidwe fiberboard (MDF).
Makampani opanga zinthu ali m'gulu lamakampani opangira matabwa.Chifukwa MDF ili ndi maubwino azinthu zabwino komanso magwiridwe antchito okhazikika,
Gawo lofunsira ku China likukulirakulira, ndipo kupanga ndi kugwiritsa ntchito kwa MDF kukuchulukirachulukira chaka ndi chaka, zomwe zakhala msika wopangira nkhuni.
Chofunikira chachikulu.
Chifukwa cha gwero lalikulu la zopangira komanso kukhazikika kwakuthupi, zopangira zotsika zimatha kusinthidwa kukhala mbale zapamwamba zokhala ndi m'lifupi mwake.
Pang'onopang'ono mapanelo opangidwa ndi matabwa alowa m'malo mwa matabwa.Pofika kumapeto kwa 2007, panali mabizinesi opangira matabwa okwana 6000 ku China.
Makampani ambiri, okhala ndi masikelo opitilira ma kiyubiki mita 80 miliyoni, ndiwo apanga komanso ogula mapanelo opangidwa ndi matabwa padziko lonse lapansi.Malinga ndi
China Forest Products Industry Association imalosera kuti malinga ndi kuchuluka kwa kukula kwa mbiri yakale yamakampani opanga nkhuni, "Eleventh Five Year Plan"
Panthawiyi, makampani opanga nkhuni ku China adzakula pamlingo wa 3-5 peresenti kuposa momwe chuma cha dziko chimakhalira nthawi yomweyo.
Ndi kukula kwachangu kwa makampani, mphamvu yopangira zinthu zazikulu za mapanelo opangidwa ndi nkhuni ikukulanso mofulumira.Pakati pa mbale zazikulu zitatu,
Plywood yakhala ndi malo olamulira kwa nthawi yayitali, kuwerengera pafupifupi 50% ya kuchuluka kwa mbale zazikulu zitatu.Komabe, chifukwa cha glue
Plywood imapangidwa makamaka ndi matabwa apamwamba kwambiri, omwe amatsatiridwa ndi msonkho wadziko lonse komanso malamulo ochotsera msonkho wakunja kwa zinthu zamatabwa zolimba.
Zotsatira za lonse, gawo la mankhwala linachepa kwambiri.Zikunenedweratu kuti gawo lake lidzatsikira ku mbale zazikulu zitatu kumapeto kwa 11th 5-year Plan.
Pafupifupi 40% ya zotulutsa zonse.MDF ndi particleboard amapangidwa ndi zotsalira za nkhalango ndi nkhuni zochepa, ndipo amapanikizidwa.
Chilimbikitso cha ndondomeko yamakampani apanyumba.Komabe, chifukwa mtundu wamapangidwe a particleboard nthawi zambiri siwokwera ndipo kugwiritsidwa ntchito popanga mipando kumakhala kwakukulu.
Zochepa, chitukukocho chikuchedwa m'zaka zaposachedwa.Poyerekeza, MDF ili ndi kuchuluka kwakukulu kogwiritsa ntchito zinthu zopangira, ndipo zopangira zake ndizabwino komanso zosinthika.
Ikhoza kukhala yokhazikika, m'mphepete mwake ndi yolimba komanso yosavuta kukonza.M'zaka zaposachedwa, ndi kuchuluka kwachangu kwa zotulutsa, kapangidwe kazinthu zopangidwa ndi matabwa zakonzedwa bwino.
Gawo ku China likukweranso kwambiri.
Laminated MDF imatanthawuza bolodi yokhala ndi chomata chambali imodzi.
MDF imatanthawuza zapakatikati kachulukidwe fiberboard sing'anga kachulukidwe fiberboard ndipo PlainMDF imatanthawuza zapakatikati kachulukidwe fiberboard.
Gulu lalikulu, lofanana ndi bolodi lopanda kanthu;Zimafotokozedwa mwatsatanetsatane m'mayiko akunja, ndipo pali matabwa omwe ali ndi luso lapadera monga DesignMDF.
Zimatanthawuza bolodi yokhala ndi mtundu wowonjezera, yomwe idapangidwa ndi kampani ya BASF ku Germany.
