Ekwenziweni kwefenisha yesimanje kanye nokuhlobisa kwezakhiwo, ibhodi-elimaphakathi ne-density fiberboard (MDF) isiphenduke impahla yebhodi esetshenziswa kakhulu ngenxa yokusebenza kwayo okuhle kakhulu. Kodwa-ke, ngezinhlobo eziningi ezahlukene zezinto zebhodi emakethe, abathengi bavame ukudideka mayelana nomehluko phakathi kwe-MDF nezinye izinto zebhodi ezivamile. Lesi sihloko sizohlaziya izici eziyinhloko ze-MDF kanye nokwehluka kwayo kwamanye amabhodi ngokuya ngekhwalithi yezinto ezibonakalayo, ukusebenza, izinhlelo zokusebenza, nobungane bemvelo.
Inqubo Yokusebenza Nokukhiqiza
I-MDF ngokuyinhloko yenziwe nge-fiber yokhuni, icindezelwe ngaphansi kwezinga lokushisa eliphezulu nokucindezela kusetshenziswa ama-resin adhesives. Isakhiwo sayo se-fiber siyafana, futhi ingaphezulu layo libushelelezi futhi liyisicaba, okuyenza ifanelekele ukucutshungulwa kahle. Ngokuphambene, i-particleboard (i-particleboard) yenziwe ngamapulangwe ezinkuni ezicindezelwe noma ama-shavings, okuholela ezinhlayiyeni ezinkulu kanye nesakhiwo esixekethile. I-plywood, ngakolunye uhlangothi, yenziwe ngezingqimba eziningi zamapulangwe amancane ahlanganiswe ndawonye, agcina okusanhlamvu okungokwemvelo futhi anikeza amandla amakhulu.
Ukuqhathaniswa Kwempahla Engokoqobo
I-MDF ivamise ukuba nokuminyana phakathi kuka-0.6-0.8 g/cm³, inikeza amandla amaphakathi, futhi imelana nokuguquka, okuyenza ifanelekele izingxenye zefenisha ezidinga indawo eyisicaba, njengezicabha zekhabethe namatafula aphansi. I-Particleboard, ngenxa yesakhiwo sayo sezinhlayiyana, inikeza umthamo oqinile wokuthwala umthwalo kodwa ukumelana nomswakama okungekuhle. I-Plywood, ngenxa yesakhiwo sayo se-laminated, inikeza ukumelana okuhle kakhulu kwe-flexural futhi ivame ukusetshenziswa ezinhlelweni ezidinga ukuqina okuphezulu, njenge-flooring kanye namafreyimu eminyango namafasitela.
Ukucutshungulwa kanye Nokwelashwa Kwangaphandle
Inzuzo enkulu ye-MDF ilele ekusithekeni kwayo kwendawo, okuvumela ukucutshungulwa okuqondile kwesibili okufana ne-veneer, ukupenda, noma ukuqoshwa, okuyenza ifanelekele imiklamo yefenisha yesimanje, emincane. I-Particleboard, ngakolunye uhlangothi, inobuso obuqinile futhi idinga ukumbozwa ngephepha le-veneer noma i-veneer. I-plywood, ngenxa yokusanhlamvu kwayo kwemvelo, ivame ukusetshenziselwa izinjongo zokuhlobisa ezigcina ukuthungwa kwezinkuni zangempela.
Ukusebenza Kwemvelo kanye Nezicelo
Ukusebenza kwemvelo kwe-MDF kuncike ohlotsheni lwe-adhesive esetshenzisiwe. I-Formaldehyde{1}i-MDI yamahhala-ehlanganisiwe ye-MDF isiphenduke imfashini emakethe. Ukusebenzisa okunamathelayo okuphansi nge-particleboard kanye ne-plywood kungase kukhulule amazinga aphezulu e-formaldehyde. Mayelana nesicelo, i-MDF isetshenziswa kabanzi kufenisha yangokwezifiso kanye nokuhlobisa kwangaphakathi; i-particleboard isetshenziswa kakhulu-efenisha ephansi noma emaphaketheni; futhi i-plywood ivame ukusetshenziswa ekwakheni isakhiwo kanye{6}}nefenisha ephezulu.
Ukuqonda umehluko phakathi kwe-MDF namanye amabhodi kuzosiza abathengi ukuthi bakhethe impahla efanele ngokwezidingo zabo zangempela. Ngokuthuthuka kobuchwepheshe bokuvikela imvelo, i-MDF isiba enye yezinketho zokuqala zokwenziwa kwefenisha ngenxa yokusebenza kwayo okulinganiselwe kanye nepulasitiki.
