Intee in le'eg bay dhumucdiisu tahay tuubada labajibbaaran ee galvanized si ay u buuxiso shuruudaha naqshadaynta qaab dhismeedka birta?

Waxaa la og yahay in tayadatuubooyinka labajibbaaran ee galvanized iyo leydiiyo habka rakibidda waxay si toos ah u saameeyaan xasilloonida dhismayaasha birta.
Waqtigan xaadirka ah, qalabka taageerada ee suuqa ku jira ayaa u badan birta kaarboon. Walxaha ceeriin ee birta kaarboon guud ahaan waa Q235 iyo Q345, kuwaas oo lagu daweeyo galvanizing kulul. Taageeradu waxay ka samaysan tahay gariiradda birta xariijimaha ah iyada oo loo marayo qaloocinta qabow, alxanka, galvanizing kulul iyo habab kale. Guud ahaan, dhumucdiisu waa inay ka badan tahay 2mm, gaar ahaan meelaha xeebaha ah, kuwa dhaadheer iyo meelaha kale ee dabayshu ka jirto, waxaa lagu talinayaa in dhumucdiisu aanay ka yarayn 2.5mm, haddii kale waxay halis u tahay inay dillaacdo birta. barta isku xirka.
Dhismayaasha waaweyn ee dhismaha, waayobirta kaarboon galvanized square iyo tuubooyinka leydi, Intee in le'eg oo dhumucdiisuna waxay tahay in la gaaro daahan zinc si loo buuxiyo shuruudaha nolosha adeegga daxalka deegaanka?
Sida aynu wada ognahay, dhumucda galvanizing kulul-muquufin waa muhiim ah tayada iyo index farsamo eeDhuumaha labajibbaaran ee galvanized, kaas oo la xidhiidha badbaadada iyo cimri dhererka qaabdhismeedka. Inkasta oo ay jiraan heerar heer qaran iyo mid xirfadeed, dhumucda dahaarka zinc ee aan u qalmin ee taageerada ayaa weli ah dhibaato farsamo oo baahsan ee taageerada.
Habka galvanizing-kuleelka waa qorshe daawaynta dusha birta ah oo xasiloon oo la isku halayn karo si looga hortago daxalka deegaanka. Waxaa jira arrimo badan oo saameeya galvanization-ku-kulul, sida ka kooban substrate birta, xaaladda dibadda (sida qalafsanaanta), cadaadiska gudaha ee substrate, iyo dhowr cabbir. Inta lagu jiro habkan, dhumucda substrate-ka ayaa saameyn weyn ku leh dhumucda galvanizing-kuleelka. Guud ahaan, marka uu saxanku sii dhumuc weyn yahay, ayaa sii weynaan doona dhumucda galvanizing-kuleelka. Taageerada dhumucda 2.0mm waxaa loo soo qaatay tusaale si loo muujiyo inta dhumucda dahaarka zinc loo baahan yahay si loo qanciyo shuruudaha adeegga daxalka deegaanka.
Ka soo qaad in dhumucda alaabta saldhigga ah ay tahay 2mm, marka loo eego heerka GBT13192-2002 heerka galvanizing kulul.
Waa maxay dhumucda lakabka galvanized ee tuubada galvanized ee loo baahan yahay si loo buuxiyo shuruudaha nolosha adeegga?
Dhuumaha labajibbaaran ee galvanized
Marka loo eego shuruudaha heerka qaran, dhumucdiisuna waxay tahay 2mm maaddada saldhigga ah waa inaysan ka yarayn 45 μm. Dhumucdiisuna waa in aanay ka yarayn 55 μm. ?
Haddii loo xisaabiyo si waafaqsan heerka qaranka, waxa ku jira zinc waa 55x7.2=396g/m2,
Nolosha adeegga ee laga heli karo afar deegaan oo kala duwan waxay ku saabsan tahay:
Aagga warshadaha culus: 8.91 sano, oo leh heerka daxalka sanadlaha ah ee 40.1;
Aagga xeebta: 32.67 sano, oo leh heerka daxalka sanadlaha ah ee 10.8;
Duleedka bannaanka: 66.33 sano, oo leh darajo daxalka sannadlaha ah ee 5.4;
Aagga magaalada: 20.79 sano, oo leh heerka daxalka sanadlaha ah ee 17.5
Haddii loo xisaabiyo iyadoo loo eegayo nolosha adeegga sawir-qaadista ee 25 sano
Markaa isku xigxiga afarta aag waa ugu yaraan:
1002.5270135437.5, ie 139 μm, 37.5 μm, 18.75 μm, 60.76 μ m.
Sidaa darteed, qaybinta magaalooyinka, dhumucda daahan zinc waa inay ahaataa ugu yaraan 65 μ M waa macquul waana lagama maarmaan, laakiin meelaha warshadaha culus, gaar ahaan kuwa leh aashitada iyo alkali, waxaa lagu talinayaa in dhumucda tuubada galvanized square. iyo dahaarka zinc waa in si habboon loogu daro.
