Momwe mungadziwire mitengo ya galvanized ya dip yotentha ndi ya cold dip galvanized

Mizati ya magetsi a pamsewuNdi malo akunja a boma omwe amakhala ndi mphepo, mvula ndi dzuwa kwa nthawi yayitali, kotero amakhala ndi dzimbiri komanso ukalamba, makamaka m'madera a m'mphepete mwa nyanja omwe ali ndi mchere komanso m'madera a kum'mwera komwe kuli chinyezi. Kukonza magetsi (Galvanization) ndi njira yotchuka kwambiri yolimbana ndi dzimbiri, yomwe imagawidwa kwambiri m'magawo awiri: kuyika magetsi m'madzi otentha (hot-dip galvanizing) ndi kuyika magetsi m'madzi ozizira (cold-dip galvanizing). Kusiyana pakati pa ziwirizi ndi kwakukulu pankhani ya mtengo, nthawi yoteteza dzimbiri (anti-corrosion lifetime) komanso mtundu wa mawonekedwe. Ogula ambiri amasokonezeka ndipo amasankha njira yolakwika. Pansipa, Tianxiang, wopanga magetsi m'misewu, adzakuphunzitsani momwe mungasiyanitsire mwachangu mitundu iwiri ya magetsi m'misewu, poganizira mfundo zawo, mawonekedwe, nthawi yoteteza dzimbiri (anti-corrosion lifetime), zochitika zomwe zingagwiritsidwe ntchito, ndi mtengo.

I. Kusiyana kwa Mfundo za Njira

1. Ndodo zomatira zotentha:

Mzati wonse wopangidwa ndi magetsi a pamsewu umaviikidwa mu zinc yosungunuka ndi kutentha kwambiri. Zinc wosanjikiza umapangidwa ndi mgwirizano wachitsulo ndi pamwamba pa chitsulo ndi mphamvu ya mankhwala yotentha kwambiri, yokhala ndi kumatirira kwamphamvu kwambiri kumakoma onse amkati ndi akunja a galvanized wosanjikiza.

2. Mizati yophimba ndi galvanized yozizira:

Njira imeneyi imatchedwanso electro-galvanizing, ndipo imathira utoto wochepa wa zinc pamwamba pa pole yowala kudzera mu njira ya electrolytic. Imamatira kunja kwa pole ndipo imalowa pang'ono mkati mwake, khoma lamkati lilibe gawo loteteza.

II. Kusiyana kwa Maonekedwe ndi Kapangidwe

1. Ndodo zoyatsira magetsi zotenthedwa ndi kuviika:

Pamwamba pake pali imvi yasiliva yoyera, yokhala ndi mitundu yofanana komanso yachilengedwe, yokhala ndi mawonekedwe ang'onoang'ono a maluwa a zinc. Ili ndi kapangidwe kolemera komanso kokhazikika ndipo imatha kuphimbidwa ndi ufa mwachindunji ndi kumatira bwino.

2. Ndodo zoyatsira magetsi zozizira:

Pamwamba pake ndi poyera kwambiri, chophimba chowala ndi chopyapyala komanso chowala. Kapangidwe kake ndi kapamwamba pang'ono ndipo mutha kuwona chophimbacho ndi maso. Madontho amatha kupanga m'mphepete ndi kuluka m'malo osaphimbidwa.

III. Kukana dzimbiri ndi kusiyana kwa nthawi yogwira ntchito

1. Nsanamira za nyali zachitsulo zotenthedwa ndi galvanized:

Kulimbana ndi dzimbiri kwambiri. M'malo abwinobwino akunja, imatha zaka 15-30 ndipo imapereka chitetezo cha dzimbiri kwa nthawi yayitali ngakhale m'malo amphepo yamkuntho ndi malo opopera mchere popanda kung'ambika kapena kusweka.

2. Nsanamira za nyali zachitsulo zozizira zoviikidwa m'madzi:

Zinc wosanjikiza ndi woonda kwambiri, ndipo chitetezo chake ndi chofooka. Chimachita dzimbiri ndi kusweka pambuyo pa zaka 3-5 za kugwiritsidwa ntchito panja, ndipo mawanga a dzimbiri adzawonekera pakatha chaka chimodzi kapena ziwiri m'madera a m'mphepete mwa nyanja. Mtengo wokwera wokonza pambuyo pake.

IV. Zochitika Zogwiritsira Ntchito ndi Malangizo Osankha

1. Ndodo zoyatsira magetsi za mumsewu zotentha:

Amagwiritsidwa ntchito pa ntchito zazikulu monga misewu ikuluikulu ya m'mizinda, magetsi akumidzi, malo okongola, madera a mphepo yamkuntho ya m'mphepete mwa nyanja, magetsi amphamvu kwambiri. Kusankha kwaukadaulo kolimba komanso kwapamwamba kwambiri.

2. Mizati ya nyali ya msewu wozizira yopangidwa ndi ma galvanised:

Kungogwiritsa ntchito misewu yakanthawi kochepa, kuunikira kwakanthawi pamalo osavuta omangira, mapulojekiti afupiafupi osakhazikika. Sikoyenera kuyika magetsi okhazikika m'maboma.

V. Kusankhana Mitengo ndi Ubwino

Kuyika ma galvanizing pa dip yotentha ndi okwera mtengo kwambiri kuposa kuyika ma galvanizing pa dip yozizira chifukwa chakuti ili ndi masitepe ambiri komanso zipangizo zambiri. Kuyika ma galvanizing pa dip yozizira ndi kosavuta komanso kotsika mtengo, komwe kumagwiritsidwa ntchito pa mitengo yotsika mtengo yotsika mtengo. Mukamagula, musamangoyang'ana mtengo wake, koma perekani patsogolo kuyika ma galvanizing pa dip yotentha kuti mupewe ndalama zowonjezera zowononga dzimbiri, kupendekeka ndikusintha pambuyo pake.

Tianxiang ndi katswiri wopanga ma galvanizing street light poles, pogwiritsa ntchito njira yonse yotenthetsera ma galvanizing kuti apange mitundu yonse yansanamira za nyali zachitsulo zomatira. Imagwira ntchito bwino ndi mphepo ndi mvula, siigwira dzimbiri, imamatirira mwamphamvu, siigwira dzimbiri, siigwira ntchito mopanda dzimbiri. Zipangizo zake ndi zolimba, ntchito yake ndi yabwino, pamwamba pake ndi posalala komanso pokongola, ndipo zinthu zonse ndi masitaelo ake zitha kusinthidwa. Gulani molimba mtima, zinthu zenizeni zokhala ndi chitsimikizo chokwanira, nthawi yayitali yogwira ntchito, palibe amalonda, thandizirani maoda ambiri ogulitsa ndi aukadaulo.
