MDF: he aha te mea reira me pehea ki te whakamahi i tenei mea?

I roto i te hanga, me te hanga o te whare noho whakamahi i te rota o ngā rauemi, engari i roto ia ratou i reira ko te hunga e kua hipokina ratou ki te kororia e kore e pirau noa. Tangohia, mo te tauira, o te papa maramara. He aha te mea te reira?

tu te ingoa mo "Fiberboard". Ko tēnei rawa whārangi, te hanga o e e wahi i te tikanga o te kōpeketanga o maramara rakau ki te tua o rerekē momo o wāhanga here.

Ka rite ki te tikanga, i roto i te apataki hou o nga resins polymeric waihanga whakamahia. I tua atu, ngā ratou ngā matū, te horo'a'tu i ngā āhuatanga hydrophobic o te rauemi oti.

Ko te na'ina'i (a reira atu nuitia whakamahia) ceresin me parawini. E mea pinepine wahi o te tāpiri rongoā horoi tapiritia,. No te mea o ratou, ko ngā tupu i runga i fiberboard te pokepokea ai. He aha te mea te reira? Nuinga o ngā wā, pērā i tāpiritanga rongoā horoi ko nga phenols, i pai te ārai i te whanaketanga o te harore me te whakangaro ratou pua.

Kua Hua fibreboard e rua ara: maroke, me te mākū. Heoi, i reira kua tikanga tata takawaenga: mākū-maroke, me te āhua-maroke.

He maroke te tikanga na'ina'i ka hanga e fiberboard (he aha te mea te reira, kua mea matou) i te tītipi rakau i roto i ngā āhuatanga noa, me te kahore mākū, i te reira ki te wai. whakahaere pereti akina te i tiketike pāmahana me te pēhanga.

āhuatanga te rauemi hua e utu iti, me noho pai o te porosity nui. tona ihirangi makuku ko 6-8 anake%.

Kei tikanga Wet o te taua wāhanga, engari kua tonoa i roto i te rû o shavings rakau, te haurangi ki te wai. Ki runga ki te putanga atu i te ruma press kua tapahia te rauemi ki ngā rau takitahi, me te te tonoa ki te dryer. awhi fiberboard taua i kē haumākū i roto i 70%. no te mea rerekē ratou ake taimaha, engari atu roa.

Ko rite ki te tikanga tuatahi whakaahuatia ana i runga i te tikanga āhua-maroke. Ko e i mua i te tono ki te swarf kiato hāwai ki te wai kia te ihirangi makuku o te rauemi hua ko 16-18% te rerekētanga anake.

rerekē tikanga mākū-maroke i te runga ake katoa i hanga e te maramara tuatahi o te pereti wai-moe te, ka te whangai reira ki te dryer me ka anake kua tonoa ki te tikanga wera-pēhi. Ko te hua ko te fiberboard kahupapa, whanaunga haumākū e tata 0%.

Kia mōhio e kore mahi matou tika tonu, kōrero ki te "tītipi". Ko te take i te maramara e te tikanga o mihini motuhake, tuatahi komukumuku nga muka o e kua hanga e kua me awhi papanga rite.

I roto i nga tau tata nei, nui atu nuitia whakamahia fiberboard sanitized. I roto i te hanga o taua awhi i runga i to ratou mata hipoki te ki te paninga multilayer. I roto i te pereti wāhanga tuatahi hipoki te ki te apa tämata motuhake, te hanga i te u turanga. Kei te tā reira tauira, pee te mata mua o te rakau.

Ko te tata kore tenei kanga wehi o te houku me te abrasion. pakeke Mata i roto i tenei take, he wanihi motuhake.

Na ka korerotia e matou ki a koutou e pā ana ki fiberboard. He aha te mea te reira, i teie nei e matau koutou. Nā ki te cheapness o nga āhuatanga rauemi me kaha te maha whakamahia reira taonga e kore e anake, engari ano hoki i roto i te ahumahi hanga.
