Mkulu wapamwamba mwambo kukula mipando melamine chinyezi umboni ndi madzi MDF

MDF ndi yamtengo wapatali chifukwa cha kapangidwe kake kopanda chilema komanso kachulukidwe kakang'ono kwambiri komwe kamalola kuti idulidwe, kuwongolera, mawonekedwe ndi kubowola mwaukhondo, yokhala ndi tsatanetsatane wazinthu zosachepera zinyalala komanso kuvala zida.Gulu la gulu, ndizovuta kumenya chifukwa chakuthupi, magwiridwe antchito ndi zokolola.MDF imamaliza bwino komanso mosasinthasintha.Malo ake osalala, osalala amapereka zotsatira zapadera kaya laminated, kusindikizidwa mwachindunji kapena penti.Mchenga wokhala ndi ma grits angapo omwe amapezeka, umachita bwino ngakhale ndi zokutira zoonda kwambiri komanso mitundu ya utoto wakuda.Kukhazikika kwa dimensional ndi phindu lina lofunika.Izi zikutanthauza kuti kusiyanasiyana kwa kutupa ndi makulidwe kumathetsedwa mukamagwiritsa ntchito mankhwalawa.Makina amisiri olondola m'zigawo zawo panthawi yopanga adzasungidwa muzinthu zomwe apanga.Ma Fasteners amakoka mwamphamvu ndipo ogwiritsa ntchito amasangalala ndi mawonekedwe olondola komanso aukhondo.
Amapereka nkhope yosalala, yosasinthasintha yomwe ilibe chilema
Ulusi wapamwamba kwambiri, woyengedwa kwambiri ndi mphamvu komanso kusasunthika kosasunthika kwa kusankha kwa Ultrastock kumapereka mikhalidwe yabwino yodula ndikuyeretsa njira.
Malo osalala opukutidwa ndikumaliza komaliza kwa grit 150
Zoyenerana bwino ndi utoto, madontho, ma veneers kapena laminates - zonse ndi zotsatira zabwino
Palibe msonkhano wofunikira

M'kupita kwa nthawi, mawu akuti "MDF" lakhala dzina generic aliyense youma-njira CHIKWANGWANI bolodi.MDF nthawi zambiri imakhala ndi 82% ya ulusi wamatabwa, 9% urea-formaldehyde resin guluu, 8% madzi, ndi 1% sera ya parafini. Kuchuluka kwa kachulukidwe ndi kagulu ka board-, standard-, kapena high-density board ndizolakwika komanso zosokoneza.Kuchulukana kwa bolodi, poyesedwa pokhudzana ndi kuchuluka kwa ulusi womwe umapita popanga gululo, ndikofunikira.Gulu lakuda la MDF lolemera 700-720 kg/m3 (44–45 lb/cu ft) limatha kuonedwa kuti ndi lolimba kwambiri pankhani ya mapanelo a ulusi wa softwood, pomwe gulu lolimba lomwelo lopangidwa ndi ulusi wolimba silili amaonedwa ngati choncho.Kusintha kwamitundu yosiyanasiyana ya MDF kumayendetsedwa ndi kufunikira kosiyanasiyana kwa ntchito zina.
MDF ikadulidwa, tinthu tambirimbiri tafumbi timatulutsidwa mumlengalenga.Chopumira chiyenera kuvalidwa ndi kudula zinthu pamalo olamuliridwa ndi mpweya wabwino.Kusindikiza m'mphepete poyera ndi njira yabwino yochepetsera kutulutsa kwa zomangira zomwe zili munkhaniyi.
Formaldehyde resins amagwiritsidwa ntchito pomanga pamodzi ulusi wa MDF, ndipo kuyezetsa kwawonetsa kuti zinthu za MDF zimatulutsa formaldehyde yaulere ndi zinthu zina zosasunthika zomwe zimayika pachiwopsezo chaumoyo pazomwe zimaganiziridwa kuti ndizosatetezeka, kwa miyezi ingapo pambuyo popanga Urea-formaldehyde. nthawi zonse amamasulidwa pang'onopang'ono kuchokera m'mphepete ndi pamwamba pa MDF.Mukajambula, kupaka mbali zonse za chidutswa chomalizidwa ndi njira yabwino yosindikizira mu formaldehyde yaulere.Sera ndi mafuta amatha kugwiritsidwa ntchito ngati zomaliza, koma sizothandiza kwambiri kusindikiza mu formaldehyde yaulere.
Sitinadziwikebe ngati mpweya wokhazikika wa formaldehyde umafika pamlingo woopsa m'malo enieni.Chodetsa nkhaŵa kwambiri ndi mafakitale omwe amagwiritsa ntchito formaldehyde.Kale mu 1987, US EPA adayiyika ngati "chotheka cha khansa ya munthu", ndipo pambuyo pa maphunziro ochulukirapo, bungwe la WHO International Agency for Research on Cancer (IARC), mu 1995, linanenanso kuti "carcinogen ya munthu".Zambiri komanso kuwunika kwazomwe zimadziwika zidapangitsa IARC kuyikanso formaldehyde ngati "carcinogen yodziwika yamunthu" yolumikizidwa ndi khansa ya m'mphuno ndi khansa ya nasopharyngeal, komanso mwina ndi khansa ya m'magazi mu June 2004.
Malinga ndi International Composite Board Emission Standards, makalasi atatu aku Europe formaldehyde amagwiritsidwa ntchito, E0, E1, ndi E2, kutengera muyeso wa kuchuluka kwa utsi wa formaldehyde.Mwachitsanzo, E0 imatchulidwa kuti ili ndi formaldehyde yosakwana 3 mg pa 100 g iliyonse ya guluu wogwiritsidwa ntchito mu particleboard ndi plywood.E1 ndi E2 amawerengedwa kuti ali ndi 9 ndi 30 g ya formaldehyde pa 100 g ya guluu, motsatana.Padziko lonse lapansi, ma certification osinthika ndi ma labels alipo pazinthu zotere zomwe zitha kukhala zachindunji kutulutsidwa kwa formaldehyde, monga za Californian Air Resources Board.
