-MDF kalai kiʻekiʻe: E0/P2 glue, density: 850-900kg/cbm, zero formaldehyde emission
-MDF maikaʻi maikaʻi (MDF lako maʻamau): E1 glue, density: 750-800kg/cbm

ʻAʻole loaʻa i ka MDF nā puʻupuʻu a i ʻole nā apo, e ʻoi aku ka like o ia ma mua o nā lāʻau maoli i ka wā e ʻoki ai a i ka lawelawe ʻana.[8] Eia naʻe, ʻaʻole isotropic holoʻokoʻa ʻo MDF, no ka mea, ua paʻa paʻa nā fibers i ka lau. ʻO ka MDF maʻamau he ʻili paʻa, palahalaha, ʻoluʻolu e kūpono ai no ka veneering, no ka mea, ʻaʻohe kumu i loaʻa i ke kelepona ma o ka veneer lahilahi e like me ka plywood. Loaʻa kahi mea i kapa ʻia ʻo "premium" MDF e hōʻike ana i nā ʻano like like ʻole ma ka mānoanoa o ka panel.
Engraving MDF: hoʻohana ʻia no ka hana ʻana i nā mea pāʻani like ʻole a me nā mea hana, kūpono no ka ʻenehana ʻokiʻoki laser.
MDF lako: hoʻohana ʻia i ka hoʻolālā ʻana i nā keʻena, nā hale lole, nā sofas, etc. ʻO ka maʻamau, hoʻomaʻamaʻa maikaʻi ʻia ka ʻili a hoʻopili ʻia me nā kala like ʻole o ka pepa melamine.
ʻO MDF haʻahaʻa haʻahaʻa: hoʻohana ʻia no ka hana ʻana i ka hoʻopili ʻana, nā pahu pahu a i ʻole nā papa ʻaʻahu, a hoʻohana pū ʻia no ka papahele a me nā pā pā.

1. MDF ʻeleʻele ʻeleʻele māmā (hōʻoiaʻiʻo)
2. ʻEleʻele ʻeleʻele kumu MDF/HDF (kauʻi)
2. MDF kumu ʻōmaʻomaʻo (wai ʻole)
3. MDF kumu ʻulaʻula (pale ahi)
Hiki iā mākou ke hana i ka plywood o nā nui āpau e kauoha ai, a hiki iā mākou ke hana i ka maikaʻi o nā huahana e like me ke koi, ʻo ia kā mākou pono.

Manaʻo ʻia ʻo MDF no kāna ʻano hana kīnā ʻole a me kona ʻano like ʻole e hiki ai ke ʻoki, hoʻopau, hoʻohua a hoʻoheheʻe maʻemaʻe, e paʻa ana i nā kikoʻī paʻakikī me ka liʻiliʻi o ka ʻōpala a me nā mea hana. Panel no ka panel, he paʻakikī e hahau no ka pono waiwai, hana mīkini a me ka huahana. Hoʻopau maikaʻi a paʻa mau ka MDF. Hāʻawi kona ʻili palahalaha a paheʻe i nā hopena maikaʻi ʻole inā laminated, paʻi pololei a pena ʻia paha. Hoʻopili ʻia me kahi ʻano o nā grits i loaʻa, hana maikaʻi ʻo ia me nā uhi uhi lahilahi a me nā kala pena ʻeleʻele. ʻO ke kūpaʻa dimensional kekahi pono nui. ʻO ia hoʻi, ʻaneʻane hoʻopau ʻia ka pehu a me ka mānoanoa i ka wā e hoʻohana ai i kēia huahana. E mālama ʻia ka mīkini hana pololei i kā lākou ʻāpana i ka wā o ka hana ʻana i ka huahana i hui ʻia a lākou e hana ai. E huki paʻa nā mea hoʻopaʻa a e hauʻoli nā mea hoʻohana hope i ke ʻano kūpono a me ka maʻemaʻe.
Hāʻawi i kahi helehelena maʻemaʻe a kūpaʻa ʻole me ke kīnā ʻole
ʻO nā fibers kiʻekiʻe, kiʻekiʻe-ikaika i hoʻomaʻemaʻe ʻia a me nā density kūlike o ka Ultrastock koho e hāʻawi i nā hiʻohiʻona kūpono e ʻoki a ala i ka hoʻomaʻemaʻe.
ʻO ka ʻili maʻemaʻe i poni ʻia me ka pau ʻana o 150 grit
Ua kūpono no nā pena, nā ʻili, nā veneers a i ʻole nā laminates - me nā hopena maikaʻi loa

I ka wā lōʻihi, ua lilo ka huaʻōlelo "MDF" i inoa maʻamau no kēlā me kēia papa fiber kaʻina hana maloʻo. ʻO ka MDF ka mea maʻamau me 82% ka pulupulu lāʻau, 9% urea-formaldehyde resin glue, 8% wai, a me 1% paraffin wax. ʻO ka mānoanoa ma waena o 500 a me 1,000 kg/m3 (31 a me 62 lb/cu ft). ʻO ka laulā o ka density a me ka hoʻokaʻawale ʻana e like me ka papa māmā, maʻamau, a i ʻole ka papa kiʻekiʻe kiʻekiʻe he kuhi hewa a huikau. ʻO ka nui o ka papa, ke loiloiʻia e pili ana i ka nui o ka fiber e komo i ka hanaʻana i ka papa, he mea nui. Hiki ke noʻonoʻo ʻia kahi pānaʻi MDF mānoanoa ma kahi mānoanoa o 700–720 kg/m3 (44–45 lb/cu ft) he ʻano kiʻekiʻe ma ke ʻano o nā paneli fiberwood, akā ʻaʻole ʻo ka panel o ka nui like i hana ʻia me nā fiberwood. i manaoia pela. ʻO ka ulu ʻana o nā ʻano like ʻole o MDF ua alakaʻi ʻia e nā pono like ʻole no nā noi kikoʻī.
Ke ʻoki ʻia ka MDF, hoʻokuʻu ʻia ka nui o nā ʻāpana lepo i ka lewa. Pono e ʻaʻahu ʻia kahi respirator a ʻoki ʻia nā mea i loko o kahi kaiapuni i hoʻomalu ʻia. ʻO ka hoʻopaʻa ʻana i nā ʻaoʻao i hōʻike ʻia he hana maikaʻi ia e kaupalena i nā hoʻokuʻu ʻana mai nā mea paʻa i loko o kēia mea.
Hoʻohana mau ʻia nā resins Formaldehyde e hoʻopaʻa i nā fibers i MDF, a ua hōʻike mau ʻia ka hoʻāʻo ʻana i nā huahana MDF e hoʻokuʻu i ka formaldehyde manuahi a me nā mea hoʻohuihui mea hoʻoheheʻe ʻē aʻe e hoʻopilikia i ke olakino ma nā ʻano i manaʻo ʻia ʻaʻole palekana, no ka liʻiliʻi o kekahi mau mahina ma hope o ka hana ʻana. ʻO ka Urea-formaldehyde. e hoʻokuʻu mālie ʻia mai nā kihi a me ka ʻili o MDF. I ka wā e pena ai, ʻo ka uhi ʻana i nā ʻaoʻao a pau o ka ʻāpana i hoʻopau ʻia he hana maikaʻi ia e sila ai i ka formaldehyde manuahi. Hiki ke ho'ohana 'ia ka pa'akai a me ka aila e like me ka ho'opau 'ana, akā, 'a'ole maika'i loa ia ma ke sila 'ana i ka formaldehyde manuahi.
ʻAʻole i hoʻoholo piha ʻia kēia mau hoʻokuʻu mau ʻana o ka formaldehyde i nā pae pōʻino i ka honua maoli. ʻO ka manaʻo nui no nā ʻoihana e hoʻohana ana i ka formaldehyde. A hiki i ka makahiki 1987, ua helu ʻia ka US EPA ma ke ʻano he "carcinogen kanaka paha", a ma hope o nā noiʻi hou aku, ʻo ka WHO International Agency for Research on Cancer (IARC), i ka makahiki 1995, ua helu pū ʻia ʻo ia ma ke ʻano he "carcinogen kanaka". ʻO ka ʻike hou aʻe a me ka loiloi o nā ʻikepili a pau i ʻike ʻia ua alakaʻi i ka IARC e hoʻokaʻawale i ka formaldehyde ma ke ʻano he "carcinogen kanaka i ʻike ʻia" pili me ka maʻi maʻi nasal sinus a me ka maʻi maʻi nasopharyngeal, a me ka leukemia paha i Iune 2004.
Wahi a International Composite Board Emission Standards, ʻekolu mau papa formaldehyde ʻEulopa i hoʻohana ʻia, ʻo E0, E1, a me E2, ma muli o ke ana ʻana o nā pae hoʻokuʻu formaldehyde. No ka laʻana, ua helu ʻia ʻo E0 ma lalo o 3 mg o ka formaldehyde mai loko o kēlā me kēia 100 g o ke kāpili i hoʻohana ʻia i ka hana ʻana i ka papa lepo a me ka lāʻau. Hoʻokaʻawale ʻia ʻo E1 a me E2 ma ke ʻano he 9 a me 30 g o ka formaldehyde i kēlā me kēia 100 g glue. Ma ka honua holoʻokoʻa, aia nā palapala hōʻoia a me ka lepili no nā huahana i hiki ke hoʻokuʻu i formaldehyde, e like me ka Californian Air Resources Board.
