Denga losweka ndi limodzi mwa mitundu yamakono yotchuka yamadenga. Katswiri wa nsalu yotchinga pansi pa denga wakhala akudziwika kwa nthawi yaitali, kuyambira nthawi ya Roma wakale. Komabe, kunali kumapeto kwa zaka za m'ma 1900, pakufika zipangizo zamakono, zomwe ndi mafilimu a PVC, kuti denga lotambasula linatengedwanso mwamsanga. Mfundo yophimbayi ndi yosavuta komanso yodziwika bwino: filimu yochepa, koma yamphamvu kwambiri ya PVC kapena nsalu yotchinga ndi yolimba kwambiri. Izi zimapangitsa kuti pakhale malo osungirako bwino, pomwe zovuta zonse mu denga ndi kuyankhulana zili zobisika.
Mitundu ya zofunda zotambasula
Kuti mudziwe kuti ndi malo ati omwe mungapange padenga, muyenera kudziwa mfundo zazikulu, zokutira, ubwino ndi zovuta.
Choyamba, monga momwe zilili kale, kutambasula chophimba kumasiyanasiyana malinga ndi zomwe zimagwiritsidwa ntchito. Choncho, pali zojambula za filimu ndi nsalu. Firimuyi ikutambasula padenga ndi mapulogalamu a PVC opunduka m'njira yoti msokowo sungathe kuoneka. Choncho, denga lamaliroli limatchedwa suture. Asanayambe kukonza, filimuyi imatenthedwa ndipo imayikidwa pa chimango. Pambuyo pozizira, filimuyi imakhala yansalu yopanda kanthu, yamphamvu komanso yosasinthika. Ndi zophweka kusamalira denga ngati, ngati kuli kofunikira, likhoza kuchotsedwa ndi kuikidwa mmbuyo. Kufunsa funso, ndi bwino kusankha chotsekeka chotsegulira, ziyenera kukumbukiridwa kuti PVC ili ndi kutsika kwa chisanu.
Nsalu kapena zotchinga zopanda chingwe ndi phula limodzi la polyester ndi kupitirira mamita asanu. Nsalu yotambasula zotchinga ndizokhalitsa, siziwopa kutentha, zimakhala zosiyana, koma mtengo wawo ndi wapamwamba kwambiri.
Kodi mungasankhe bwanji mtundu wa denga lotambasula?
Musanasankhe mtundu wa denga lotambasula, muyenera kudziwa momwe imaonekera. Pano mungasankhe mitundu iwiri yokha: zofiira ndi matt. Kuphwasula kutambasula kokongola kukuwoneka kwakukulu mu zamkati zamakono, kukulolani kuti mupange masewera apadera a kuwala ndi kusinkhasinkha. Nsalu ya matte imapereka chithunzi chokhazikika pokha popanda chithunzi chodziwika bwino, motero nthawi zambiri chimagwiritsidwa ntchito pang'onopang'ono mkatikatikatikati, ndikusuntha mtundu wake chifukwa cha kusapezeka kwa chiwonetsero. Denga lotambasula limatha kukhala ndi ziwalo zosiyana, kuyimitsa velvet kapena nsalu. Tiyenera kukumbukira kuti nsalu yopanda nsalu ikhoza kukhala ndi matte.
Ndipo komabe, mungasankhe bwanji mtundu wa denga? Choyamba, chiyenera kukhala chophatikizidwa m'kati mwazitali. Kutsekedwa kwazitali kuli ndi mitundu yambiri ya maonekedwe ndi mithunzi, zimatha kuyika pamwamba pazojambula, kujambula zithunzi ndi zina zambiri. Chachiwiri, mtundu wa denga ukhoza kusokoneza zofooka ndikugogomezera ulemu wa chipinda. Mwachitsanzo, posankha mtundu wakuda, mukhoza kuwonekera "pansi" padenga kwambiri ndikupangitsa kuti chipindachi chikhale chogwirizana kwambiri.
Kuphika kwa nkhondo kumagwirizanitsidwa bwino ndi zinthu za gypsum plasterboard, zomwe zimapanga zokondweretsa zamagulu osiyanasiyana. Choncho,
Monga lamulo, funso lomalizira likubuka: ndiwopanga wotani wotambasulira chophimba kuti asankhe? Ngati mukufuna kuti zovala zikhale nthawi yayitali, musasinthe, musasinthe mtundu (ndi zaka zosachepera zokhala ndi moyo zaka 10), ndi bwino kumvetsera malemba abwino. Ogulitsa kwambiri omwe amapereka zotchinga ku Ulaya ali m'mayiko otsatirawa: France, Germany, Switzerland, Russia ndi China.
