Sidee loo doortaa qafiska digaagga ee saxda ah?

Iyadoo la horumarinayo baaxadda/xoogga badan ee beerashada digaagga, beeraleyda digaagga ayaa aad u badan oo doortaqafis digaag jiifinbeerashada sababtoo ah beerashada qafiska waxay leedahay faa'iidooyinka soo socda:

(1) Kordhi cufnaanta kaydka. Cufnaanta qafisyada digaagga ee saddex-geesoodka ah waxay ka badan tahay 3 jeer ka badan tahay qafisyada fidsan, in ka badan 17 digaag oo jiifa ayaa la kor u qaadi karaa mitirkiiba laba jibbaaran;

(2) Kaydi quudinta. Digaagga waxaa lagu hayaa qafisyo, xaddiga jimicsiga waa la dhimayaa, isticmaalka tamarta ayaa yar, qashinka walxahana waa la dhimayaa. Hirgelinta bacriminta macmalka ah waxay yareyn kartaa saamiga diiqa;

(3) Digaaggu ma taabtaan saxarada, taas oo sahlaysa ka hortagga cudurrada faafa ee xoolaha;

(4) Ukuntu waa nadiif, taas oo ka saari karta ukunta bannaanka buulka.

Si kastaba ha ahaatee, beeraley badan ma yaqaanaan tiknoolajiyada wax-soo-saarkaqafisyada digaaggaSidee bay u dooran karaan qafisyo digaag tayo wanaagsan leh oo cimri dheer leh? Qalabka dhaqidda digaagga ee otomaatiga ah, doorashada qafisyada digaagga ayaa ka muhiimsan taabashada tooska ah ee digaagga.Waqtigan xaadirka ah, waxaa suuqa ku jira 4 nooc oo qafis ah oo ay beeraleyda digaagga ka dooran karaan:

1. Qabow galvanized.

Galvanizing-ka qabow, oo sidoo kale loo yaqaan electrogalvanizing, wuxuu leeyahay lakab galvanized khafiif ah. Faa'iidooyinka galvanizing-ka qabow waa dusha siman iyo dhalaal sare; si kastaba ha ahaatee, guud ahaan waxaa loo isticmaalaa 2-3 sano si uu u miridho wuxuuna leeyahay cimri 6-7 sano ah. Galvanizing-ka qabow waxaa sidoo kale loo qaybin karaa midab galvanized zinc ama zinc cad, iwm., saameyntu waa isku mid.

2. Kuleylka-maquufinta.

Galvanizing kulul, oo sidoo kale loo yaqaan galvanizing kulul, dhumucda lakabka galvanized guud ahaan waa in ka badan 80μm in loo tixgeliyo mid u qalma, guud ahaan ma fududa in la miridho, iska caabinta daxalka oo sareysa, guud ahaan waxaa loo isticmaali karaa 15 sano ilaa 20 sano, laakiin faa'iidada ayaa ah in galvanization-ka barkadda galvanizing-ka aan sinnayn, taasoo keenta burrs badan, taas oo u baahan habayn gacanta ah marxaladda dambe.Baqashada digaagga galvanized ee kulul-maquufintawaa doorashada koowaad ee beeraha otomaatiga ah, laakiin qiimuhu guud ahaan wuu ka sarreeyaa kuwa kale.

3. Ku buufi digaagga meesha lagu nasto.

Dahaarka budada ah waxaa lagu nuugaa qafiska iyada oo loo marayo soo jiidashada koronto joogto ah oo danab sare leh, taasoo sameysa filim fosfate ah oo aad u adkaysta daxalka inta u dhaxaysa qafiska digaagga iyo dahaarka, laakiin qafiska digaagga ee la buufiyay ayaa u badan inuu ku dhego digada digaagga, mana fududaan doonto muddo dheer. Way fududahay in la gaboobo oo la dhaco. Noocan qafiska digaagga ah waa mid aad dhif u ah suuqa, suuquna waa mid yar.

4. Qafis digaag ah oo aluminium ah oo zinc ah.

Siligga dahaarka zinc-aluminium ayaa loo isticmaalaa alxanka tooska ah, mana loo baahna habayn dheeraad ah marxaladda dambe. Shuruudaha alxanka ee noocan ah ee shabagga qafiska digaagga ayaa aad u sarreeya. Haddii alxanku aanu fiicnayn, kala-goysyada alxanka ayaa miridhku noqon doonaa. Haddii habka si fiican loo barto, cimriga adeeggu guud ahaan wuxuu gaari doonaa in ka badan 10 sano. Inta badan qalabka la soo dejiyo wuxuu isticmaalaa noocan shabagga.

Marka la eego adkeysiga, kululaynta galvanizing > daawaha zinc-aluminium > buufinta > qabow galvanizing.

Nala soco waxaan cusbooneysiin doonnaa macluumaadka taranka.
