MDF: kuyini? zama ukuqonda

okunezinhlobonhlobo elikhulu zokwakha kanye lula, futhi ngesikhathi esifanayo nzima ukukhetha yomuntu yesimanje. Ngokwesibonelo, abaningi bethu baye ngisho wezwa izwi elinje MDF. Ukuthi kuyini, akubona bonke uyazi, futhi emagama nobunzima ezingavela. Eqinisweni, ngaphansi kwalesi isifinyezo efihla fiberboard, lapho i ukuminyana isilinganiso.

Lapho ukusebenzisa?

Okokuqala, ake sithi ukuthi ukubukeka kwazo liyadingeka impahla yesimanje ubuchwepheshe eziphambili ngesisekelo okuyinto ezikhiqizwa fibreboard. I MDF kungekho binders zokwenziwa, isetshenziswa esikhundleni lignin kakade oluqukethwe Ukwakheka kwezinkuni. Futhi uthi kuyinto imvelo futhi iphephile impilo yomuntu izinto ezifana MDF, okuyinto enamathela ahlukile can ngisho ijazi izindonga amakhabethe nokunye ngomuthi. Ngo inqubo ukukhiqizwa okokusebenza iba:

- amelana esivuthayo futhi lokushisa ukweqisa;

- eqinile;

- amanzi nemithi.

Lokunye lokubaluleke kakhulu iqiniso lokuthi IDF kwenziwe imishini zobuchwepheshe, ngakho ubuso bayo zingelashwa kalula. Ngaphezu kwalokho, kungenzeka ukukhulula impahla kunoma yiluphi uhlobo, ngisho esiyinqaba. Staining, laminating, varnishing noma enamels - konke MDF kungaba ahlinzwe. Kuyini futhi yiziphi izici zayo we impahla, siyazwisisa.

udonga isigubungelo

Ukuhlobisa ifulethi noma indlu ezweni MDF panel ezindongeni isikhathi eside luvamile. ithandwa kangaka kungenxa yokuthi okubalulekile lula babuthane bese ukufaka ngoba ungakwazi ngumnikazi ngisho. ukhetho olukhulu nombala onjani izixazululo uvumele eyolanda design nganoma yisiphi design wesitayela ingaphakathi. Panel ukukhwezwa ngqo iziqondiso, okuyinto anamekwe odongeni ngaphambili.

Ngaphambi kokufaka amaphrofayli, izindonga kumele selashwe udokotela Ukwakheka ekhethekile - le uyozivikela nokusondelana isikhunta nezinto ezincane eziphilayo, futhi umswakama. Amaphrofayli kufanele kube eduze eduze komunye nomunye, ukushiya kungekho izikhala phakathi kwawo. Ukuze amalungu afanayo okuholela ubukeka nobuhle obukhona futhi organically, udinga ukusizakala ezihlukahlukene emakhoneni futhi emapheshana zokuhlobisa, okuyinto linamathele iziqeshana noma i-glue. Ungakhohlwa mayelana ukupholisa eliphakathi kodonga kanye panel.

Kanjani ukuze uthole MDF?

Ukukhiqizwa indaba eyenziwa ngezigaba eziningana. Okokuqala, impahla eluhlaza kuvuna (ngokuvamile lena ugodo evamile). I izingodo debarked, oqoshiwe zibe chips encane, uthola eziningi ufuna ukuqeda doti, isihlabathi, futhi equliswa kushunqe. Ngemva kushunqe chips ingumhlabathi, yengezwe resin esibophezelayo. IMisa ethunyelwe dryer, ngemva kwalokho-ke esuswa emoyeni. Kakade emshinini ukwakha kukhona izinkuni fibre (okuthiwa fibre). Nge umshini ukwakha mass onomfutho umata bedle nabezindaba kuba extruded emoyeni asele.

Isinyathelo esibaluleke kunazo zonke kukhiqizwe MDF ezihlangene. Kuyini lokhu? Lokhu inqubo, lapho mat ukhuni fibre is phansi yokugcina ngokucindezela, bese usika futhi selehlile. Ukuze udlulisele ukubukeka yobuhle okuholela panel ngaphansi ukugaya, ukushuba we amashidi edlelana, izici ziyasuswa. Ukuze uthole MDF, kubalulekile ukusebenzisa chips izinkuni, urea-formaldehyde inhlaka, ammonium chloride futhi upharafini. Gcina izinto kungenziwa kuphela igcwele egumbini lapho izinga nomswakama esingeqile ku-70% kanye lokushisa esiphezulu esingu-25 ° C.
