Powonetsa zinthu zapamwamba komanso zamtengo wapatali, timalimbikitsa kugwiritsa ntchito mashelefu amatabwa, omwe amathandiza kwambiri powonetsera zinthu zonse ndi kukwezera zithunzi zamakampani.Kuphatikiza apo, mukamagwiritsa ntchito mashelufu owonetsera matabwa, tidalemba momwe ma board ena amagwirira ntchito kuti muwonetsere.

Blockboard: zabwino zoteteza chinyezi, palibe utoto wachindunji.

Pakati pa blockboard ndi pachimake chopangidwa ndi matabwa achilengedwe, ndipo mbali ziwirizo zimakutidwa ndi zowonda kwambiri, zomwe ndi chimodzi mwazinthu zofunika kwambiri popanga mawonetsero.Itha kugwiritsidwa ntchito pakatikati pamayendedwe okwera, chitseko chamatabwa ndi mawonekedwe achiwonetsero chachiwonetsero, ndikuchita bwino kosalowa madzi komanso chithandizo champhamvu chamapangidwe.

Posankha, muyenera kuyang'ana matabwa ake amkati, omwe sayenera kusweka kwambiri, ndi bolodi lolumikizira lomwe lili ndi kusiyana kwa pafupifupi 3mm pakati pa nkhuni.Chifukwa njere zamatabwa zomwe zimawonekera pamwamba sizikhala zokongola, sizimapenta mwachindunji, ndipo plywood ya veneer nthawi zambiri imayikidwa.Zomangamanga zamatabwa monga zowonetsera ndi zokongoletsera zopangidwa ndi iwo ziyenera kumangidwa ndi matabwa olimba, kenaka kupaka utoto kapena kumata ndi matabwa osayaka moto kuti ziwonetsedwe bwino.

Chiwonetsero cha bolodi chophatikizika: sichosavuta kuyimitsa

Uwu ndi mtundu watsopano wa zinthu zamatabwa zolimba, zomwe zimapangidwa ndi zipika zamtundu wapamwamba kwambiri zomwe zimatumizidwa kunja ndi kukonzanso kwakukulu, ndipo zimakhala ngati bolodi lokhala ndi chala.Chifukwa cha njira zosiyanasiyana, bolodi lamtunduwu limakhala ndi ntchito yabwino kwambiri yoteteza chilengedwe, yomwe ndi 1/8 yazomwe zili zovomerezeka za formaldehyde mu blockboard.Kumbali ina, bolodi lamtunduwu lopangidwa ndi matabwa olimba monga American spruce amatha kupakidwa utoto mwachindunji, kupulumutsa njira poyerekeza ndi bolodi.

Chiwonetsero cha bolodi chapakati chapakati: kukhazikika bwino

MDF amapangidwa ndi kukanikiza nkhuni ufa utuchi, ndi flatness wabwino, koma osauka kukana chinyezi.Mosiyana ndi zimenezi, mphamvu yogwira misomali ya bolodi la density board ndi yosauka, ndipo zomangira zimakhala zosavuta kumasula pambuyo pozimitsidwa.Chifukwa mphamvu ya kachulukidwe bolodi si mkulu, n'kovuta kukonza kachiwiri, choncho kawirikawiri amagwiritsidwa ntchito ngati kabati, koma makamaka ntchito kupaka pamwamba pa pepala utoto.

Chokongoletsera chojambula cha plywood itatu: tirigu wolemera wamatabwa

Amatchedwanso plywood ndi plywood.Magawo osiyanasiyana ali ndi mayina osiyanasiyana.Ubwino wake ndi zovuta zake makamaka zimadalira zipangizo ndi mitundu yamatabwa, monga mapulo plywood, ndi mizere yomveka bwino komanso yowolowa manja;Plywood ya Oak yokhala ndi mizere yowongoka ndi yadongosolo.Nkhaniyi imagwiritsidwa ntchito popanga mawonekedwe owonetserako ndipo imachitidwa ndi utoto wotseguka, kotero zotsatira zake zimakhala zapamwamba kwambiri.

Pakalipano, zotsatira zambewu zamatabwa popanga chiwonetserochi makamaka ndi plywood ya veneer, ndiko kuti, matabwa olimba kwambiri a matabwa aikidwa pa plywood mu fakitale.Plywood ya veneer ndiyosavuta kugwiritsa ntchito ndipo mtengo wake ndi wocheperako.

Kugula kwa nkhuni kumayenera kudalira kaye ngati kumagwirizana ndi chilengedwe.Malinga ndi malamulo, umuna wa formaldehyde wa mitengo yokongoletsera mall uyenera kukhala wochepera kapena wofanana ndi 1.5 mg pa lita.Ngati ipitilira 5 mg pa lita imodzi, ndiyosavomerezeka.
