N'zodziwika bwino kuti khalidwe lamachubu opangidwa ndi magalasi a sikweya ndi amakona anayindipo njira yokhazikitsira imakhudza mwachindunji kukhazikika kwa nyumba zachitsulo.
Pakadali pano, zipangizo zothandizira zomwe zili pamsika makamaka ndi chitsulo cha kaboni. Zipangizo zopangira chitsulo cha kaboni nthawi zambiri zimakhala Q235 ndi Q345, zomwe zimakonzedwa ndi galvanizing yotentha. Chithandizocho chimapangidwa ndi strip steel coil kudzera mu coil yopindika, kuwotcherera, galvanizing yotentha ndi njira zina. Kawirikawiri, makulidwe ake ayenera kukhala oposa 2mm, makamaka m'madera ena a m'mphepete mwa nyanja, okwera kwambiri komanso m'madera ena amphepo, ndikulimbikitsidwa kuti makulidwe ake asapitirire 2.5mm, apo ayi pangakhale chiopsezo chong'ambika pamalo olumikizira chitsulo.
Mu nyumba zazikulu, kwamapaipi achitsulo cha kaboni opangidwa ndi chitsulo chagalasi lalikulu ndi lamakona anayiKodi chivundikiro cha zinc chiyenera kupangidwa ndi makulidwe angati kuti chikwaniritse zofunikira pa nthawi ya dzimbiri yogwiritsidwa ntchito pa chilengedwe?
Monga tonse tikudziwa, makulidwe a galvanizing yotentha ndi chizindikiro chofunikira komanso chaukadaulo chachitoliro cha sikweya chopangidwa ndi magalasi, zomwe zikugwirizana ndi chitetezo ndi kulimba kwa nyumbayo. Ngakhale pali miyezo yadziko lonse komanso yaukadaulo, makulidwe osakwanira a zinc coating a chithandizochi akadali vuto lalikulu laukadaulo la chithandizochi.
Njira yothira ma galvanizing yothira ma galvaning ndi njira yokhazikika komanso yodalirika yothanirana ndi dzimbiri la chitsulo kuti isawonongeke ndi dzimbiri la chilengedwe. Pali zinthu zambiri zomwe zimakhudza ma galvanizing othira ma galvaning, monga kapangidwe ka chitsulo, mawonekedwe akunja (monga kuuma), kupsinjika kwamkati kwa substrate, ndi kukula kosiyanasiyana. Panthawiyi, makulidwe a substrate amakhudza kwambiri makulidwe a galvanizing yothira ma galvaning. Nthawi zambiri, mbaleyo ikakhala yokhuthala, makulidwe a galvanizing yothira ma galvaning amakula. Thandizo lokhala ndi makulidwe a 2.0mm limatengedwa ngati chitsanzo kuti liwonetse kuchuluka kwa makulidwe a zinc coating omwe amafunikira kuti akwaniritse zofunikira pa moyo wa dzimbiri la chilengedwe.
Tangoganizani kuti makulidwe a zinthu zothandizira ndi 2mm, malinga ndi muyezo wa GBT13192-2002 wotentha wopangira ma galvanizing.
Kodi makulidwe a chitoliro cha galvanized cha chitoliro cha galvanized ndi otani kuti akwaniritse zofunikira pa moyo wa ntchito?
Chitoliro cha sikweya chopangidwa ndi galvani
Malinga ndi zofunikira za muyezo wa dziko, makulidwe a 2mm base hardware sayenera kuchepera 45 μ m. Kukhuthala kofanana sikuyenera kuchepera 55 μ m. Malinga ndi zotsatira za mayeso owonetsa kutentha kwa mpweya omwe adachitika ndi Japanese Hot Dip Galvanizing Association kuyambira 1964 mpaka 1974. Kodi makulidwe a galvanized layer ya galvanized square payipi ndi otani kuti akwaniritse zofunikira za moyo wautumiki?
Ngati zinki yawerengedwa motsatira muyezo wa dziko, kuchuluka kwa zinki ndi 55x7.2=396g/m2,
Nthawi yogwiritsira ntchito yomwe imapezeka m'malo anayi osiyanasiyana ndi yokhudza:
Malo olemera a mafakitale: zaka 8.91, ndi digiri ya dzimbiri ya pachaka ya 40.1;
Malo a m'mphepete mwa nyanja: zaka 32.67, ndi digiri ya dzimbiri ya pachaka ya 10.8;
Kunja: zaka 66.33, ndi digiri ya dzimbiri ya pachaka ya 5.4;
Dera la mumzinda: zaka 20.79, ndi digiri ya dzimbiri ya pachaka ya 17.5
Ngati ziwerengedwa malinga ndi moyo wautumiki wa photovoltaic wa zaka 25
Ndiye ndondomeko ya madera anayi ndi osachepera:
1002.5270135437.5, ie 139 μ m, 37.5 μ m, 18.75 μ m, 60.76 μ m.
Chifukwa chake, pogawa madera a m'mizinda, makulidwe a zinc sayenera kupitirira 65 μ M ndi oyenera komanso ofunikira, koma m'madera akuluakulu amafakitale, makamaka omwe ali ndi dzimbiri la asidi ndi alkali, tikulimbikitsa kuti makulidwe a chitoliro cha galvanized square ndi zinc covering awonjezeredwe bwino.
