MDF: ntoni na nokuba ukusebenzisa njani le nto?

Xa ukulungiswa kunye nokwakhiwa kwezakhiwo zokuhlala basebenzisa ezininzi izinto, kodwa phakathi kwazo kukho abo abagubungele ngokwabo ngozuko nelingambatshiyo nje. Ngokomzekelo, abantu ichipboard. Yintoni na?

Igama imela "Fiberboard". Le izinto sheet, imveliso leyo ethatha indawo esebenzisa ucinezelo chips iinkuni kongezwe iintlobo ezahlukeneyo inamacandelo yokubopha.

Njengoko umthetho, ukuba umzimba wenyama wakutshanje kuphando lwe-nentlaka zokwenziwa polymeric ezisetyenzisiweyo. Ukongeza, ziquka izinto ezahlukeneyo, yokunikwa iimpawu hydrophobic umbandela ogqityiweyo.

Le ceresin (esetyenzisiweyo kwaye ngoko ngokuqhelekileyo ngaphezulu) libiza kancinane kwaye kweparafini. Ngokufuthi, inxalenye additive kubola longeziwe. Ngenxa yazo, ukungunda cishe amila fiberboard. Yintoni na? Amaninzi, ezifana njengoko ongeziweyo kubola le phenols, ethintela ngempumelelo uphuhliso nomngundo nokutshabalalisa imbewu yabo.

Iveliswe fibreboard iindlela ezimbini: nobushushu. Noko ke, kukho kuye iindlela kutshanje intermediate: manzi-ezomileyo kunye nezo owomileyo.

Le ndlela ingenandleko owomileyo xa fiberboard (oko kukuthi, siye sathi) amiliswe ukusuka chips iinkuni kwiimeko eziqhelekileyo yaye ngaphandle ilele ngamanzi. ipleyiti ngokucindezela kwenziwa lobushushu eliphezulu kunye noxinzelelo.

Le zezinto ezithile eziziphumo luphawulwa zamaxabiso aphantsi, kunye lula porosity ebalulekileyo. Umxholo wayo ukufuma kuli 6-8% kuphela.

indlela emanzi iqulathe izigaba ezifanayo, kodwa ngokucinezelwa imbuphu iinkuni ithunyelwe, ukuba tixi ngamanzi. Emva uphume egumbini cofa umbandela isikwe amaphepha ngamnye kwaye zithunyelwa isomisi. iiphaneli fiberboard ezinjalo sele ukufuma ngaphakathi 70%. ngokuba bengafani ubunzima ngakumbi, kodwa ixesha elide ngakumbi.

Indlela semi-owomileyo kuyafana indlela yokuqala echazwe ngasentla. Umahluko kuphela kukuba phambi kokuba isicelo swarf compact nisela amanzi ukwenzela ukuba isiqulatho sokufuma umbandela eliphuma 16-18%.

indlela emanzi-owomileyo kwahlukile zonke ngasentla ukuba chip yokuqala kwipleyiti ngamanzi buzane ibunjiwe, ngoko kondliwa dryer uze kuphela ithunyelwe inkqubo eshushu-inki. Ngenxa yoko fiberboard ngamaplanga, ukufuma ozalanayo leyo phantse 0%.

Qaphela ukuba ungenzi ngendlela echanekileyo, ebhekisela i "chips". Isibakala sokuba engenelela ngokusebenzisa oomatshini ezizodwa, kuqala bezihlikihla Imicu apho sele kwasekwa iipanele ilaphu lilungile.

Kwiminyaka yakutshanje, kokukhona eziqhele ukusetyenziswa fiberboard sanitized. Ekwenziweni iipaneli kumphezulu wazo wambu ukutyabeka multilayer. Xa plate isigaba sokuqala wambu primer ngomaleko ezikhethekileyo, ukudala isiseko esomeleleyo. It Libhalwe ipateni, bexelisa umphezulu eliqhelekileyo kweenkuni.

Le isitovu uphantse Musa ukoyika ukufuma lingonakali. Umphezulu ukuqaqadeka kulo mzekelo, a ivanishi okhethekileyo.

Ngoko ndandinixelele fiberboard. Yintoni na, ngoku uyazi. Ngenxa cheapness lepropati eziphathekayo kunye namandla nto idla ngokusetyenziswa ifanitshala nje kuphela, kodwa kwishishini lokwakha.
