Umgangatho ophezulu wefanitshala yesiko imelamine ubungqina bokufuma kunye neMDF engenamanzi

I-MDF ixabiswa ngokubunjwa kwayo okungenasiphako kunye noxinaniso olufana kakhulu oluvumela ukusika, ukujikeleza, ukubumba kunye nokubhobhoza ngokucocekileyo, ubambe iinkcukacha eziyinkimbinkimbi kunye nobuncinci benkunkuma kunye nokunxiba izixhobo.Iphaneli yephaneli, kunzima ukubetha ukusebenza kakuhle kwezinto, ukusebenza komatshini kunye nemveliso.I-MDF iphinda igqibe kakuhle kwaye ingaguquki.Umphezulu wayo othe tyaba, ogudileyo unika iziphumo ezibalaseleyo nokuba i-laminated, iprintwe ngokuthe ngqo okanye ipeyintiwe.Ifakwe isanti ngoluhlu lweegrits ezikhoyo, iqhuba kakuhle nakwizinto ezingaphezulu ezibhityileyo kunye nemibala yepeyinti emnyama.Uzinzo lweDimensional yenye inzuzo ebalulekileyo.Oko kuthetha ukuba ukudumba kunye nokutyeba kuyapheliswa xa usebenzisa le mveliso.Umatshini weengcibi ezichanekileyo kwiindawo zabo zecandelo ngexesha lemveliso ziya kugcinwa kwimveliso edibeneyo abayivelisayo.Iifasteners ziya kutsala ngokuqinileyo kwaye abasebenzisi bokugqibela bayakonwabela ukulunga okuchanekileyo kunye nenkangeleko ecocekileyo.
Inikeza ubuso obugudileyo, obuhambelanayo obungenasiphako ngokupheleleyo
Umgangatho ophezulu, i-high-energy-refined fibers kunye nokuxinana okungaguqukiyo kwe-Ultrastock ekhethiweyo inikezela ngeempawu ezifanelekileyo zokusika kunye nokucoca indlela.
Umphezulu ogudileyo ogudisiweyo kunye negrit yokugqibela eyi-150
Ngokufanelekileyo ngokufanelekileyo iipeyinti, amabala, i-veneers okanye i-laminates-zonke zineziphumo ezigqwesileyo
Akukho ndibano ifunekayo

Ngokuhamba kwexesha, igama elithi "MDF" liye laba ligama eliqhelekileyo kuyo nayiphi na ibhodi yefiber eyomileyo.I-MDF ngokuqhelekileyo yenziwe nge-82% ye-wood fibers, i-9% yeglue ye-urea-formaldehyde resin, i-8% yamanzi, kunye ne-1% yeparafini yewax. Uluhlu loxinaniso kunye nokuhlelwa njengokukhanya-, umgangatho-, okanye ibhodi yoxinano oluphezulu aligama elibi kwaye liyabhidisa.Ubuninzi bebhodi, xa kuvavanywa ngokumalunga nobuninzi befiber ehamba ekwenzeni ipaneli, kubalulekile.Iphaneli ye-MDF engqindilili kuxinaniso lwe-700–720 kg/m3 (44–45 lb/cu ft) inokuthathwa njengoxinaniso oluphezulu kwimeko yeepaneli zefibre ye-softwood, ngelixa ipaneli yoxinaniso olufanayo olwenziwe ngeentsinga zomthi oqinileyo ithathwa njalo.Ukuvela kweentlobo ngeentlobo zeMDF kuye kwaqhutywa ziimfuno ezahlukeneyo zezicelo ezithile.
Xa i-MDF inqunyulwa, inani elikhulu lamasuntswana othuli akhululwa emoyeni.Isixhobo sokuphefumla kufuneka sinxitywe kwaye isixhobo sisikwe kwindawo elawulwayo nengena umoya.Ukutywina imiphetho eveziweyo luqheliselo olulungileyo lokucutha izinto ezikhutshwayo kwizibophelelo eziqulethwe kwesi sixhobo.
Iintlaka ze-formaldehyde ziqhele ukusetyenziselwa ukubopha ndawonye iintsinga kwi-MDF, kwaye uvavanyo luye lwabonisa ukuba iimveliso ze-MDF zikhupha i-formaldehyde yamahhala kunye nezinye iikhompawundi eziguquguqukayo ze-organic ezibeka umngcipheko wezempilo kwiindawo ezithathwa njengezingakhuselekanga, ubuncinane kwiinyanga ezimbalwa emva kokwenziwa kwe-Urea-formaldehyde. isoloko ikhutshwa kancinci emacaleni kunye nomphezulu we-MDF.Xa upeyinta, ukugubungela onke macala eqhekeza eligqityiweyo yinto efanelekileyo yokutywina kwi-formaldehyde yamahhala.I-wax kunye ne-oyile ezigqityiweyo zinokusetyenziswa njengokugqiba, kodwa azisebenzi kangako ekutywineni kwi-formaldehyde yasimahla.
Ukuba oku kukhutshwa rhoqo kwe-formaldehyde kufikelela kumanqanaba anobungozi kwindawo yelizwe lokwenyani akukaqinisekiswa ngokupheleleyo.Eyona nkxalabo iphambili kumashishini asebenzisa i-formaldehyde.Ukuza kuthi ga ngo-1987, i-US EPA yachaza ukuba "i-carcinogen enokwenzeka yomntu", kwaye emva kwezifundo ezininzi, i-WHO International Agency for Research on Cancer (IARC), kwi-1995, iphinde ichaze "njenge-carcinogen enokwenzeka yomntu".Ulwazi olongezelelweyo kunye novavanyo lwazo zonke iinkcukacha ezaziwayo zikhokelele i-IARC ukuba iphinde ihlele i-formaldehyde njenge "carcinogen yabantu eyaziwayo" ehambelana nomhlaza we-sinus yeempumlo kunye nomhlaza we-nasopharyngeal, kwaye mhlawumbi ne-leukemia ngoJuni ka-2004.
Ngokutsho kweMigangatho yokuThuthwa kweBhodi yeZizwe eziManyeneyo, iiklasi ezintathu ze-European formaldehyde zisetyenziswa, i-E0, i-E1, kunye ne-E2, ngokusekelwe kumlinganiselo wokukhutshwa kwe-formaldehyde.Ngokomzekelo, i-E0 ihlelwa njengengaphantsi kwe-3 mg ye-formaldehyde kwi-100 g yeglue esetyenziswe kwi-particleboard kunye ne-plywood fabrication.I-E1 kunye ne-E2 zihlelwa njenge-9 kunye ne-30 g ye-formaldehyde nge-100 g yeglue, ngokulandelanayo.Kuwo wonke umhlaba, iziqinisekiso eziguquguqukayo kunye nezikimu zokuleyibheli zikhona kwiimveliso ezinjalo ezinokucaca ukukhutshwa kwe-formaldehyde, njengaleyo yeBhodi yeMithombo yoMoya yaseCalifornia.
