Kiʻekiʻe kiʻekiʻe maʻamau lako melamine moisture hōʻoia a me ka wai MDF

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 kūpono kūpono a me ke ʻano 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 poli 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
ʻAʻole pono ka hui ʻana

I ka manawa lōʻihi, ua lilo ka huaʻōlelo "MDF" i inoa maʻamau no kēlā me kēia papa 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 kiʻekiʻe 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 ʻano hoʻomalu a me ka ea.ʻO ka hoʻopaʻa ʻana i nā ʻaoʻao i hōʻike ʻia he hana maikaʻi ia e kaupalena i nā hoʻokuʻu ʻana mai nā mea hoʻopaʻa 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 hoʻopuka i ka formaldehyde manuahi a me nā mea hoʻohui kino 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 pena ʻana, 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 ka 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 ka US EPA iā ia ma ke ʻano he "probable human carcinogen", 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" i 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 kolu 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 like ʻole a me ka lepili no nā huahana i hiki ke hoʻokuʻu i formaldehyde, e like me ka Californian Air Resources Board.
