Kodi mizati ya mumsewu ya dzuwa ikhale yozizirira kapena malata otentha?

Masiku ano, ma coil achitsulo a premium Q235 ndiye zinthu zodziwika kwambirimitengo yoyendera dzuwa. Chifukwa chakuti magetsi a m’misewu yoyendera dzuwa amawombedwa ndi mphepo, dzuwa, ndi mvula, amakhala ndi moyo wautali chifukwa chakuti amatha kupirira dzimbiri. Chitsulochi chimapangidwa ngati malata kuti izi zitheke.

Pali mitundu iwiri ya zinki plating: otentha-kuviika ndi ozizira-kuviika galvanizing. Chifukwaotentha-kuviika kanasonkhezereka mizati zitsulozimagonjetsedwa ndi dzimbiri, nthawi zambiri timalangiza kuzigula. Kodi pali kusiyana kotani pakati pa galvanizing ya dip yotentha ndi yozizira, ndipo n'chifukwa chiyani mitengo yamalati ya dip yotentha imakhala yosachita dzimbiri kwambiri? Tiyeni tiwone za Tianxiang, fakitale yotchuka yaku China yamitengo.

1) Cold Galvanizing (Amatchedwanso electro-galvanizing): Pambuyo pochotsa mafuta ndi pickling, chitsulocho chimayikidwa mumchere wa zinki. Njira yothetsera vutoli imalumikizidwa ndi electrode yoyipa ya zida za electrolysis, ndipo mbale ya zinc imayikidwa moyang'anizana ndi ma elekitirodi abwino. Mphamvu ikayatsidwa, pamene magetsi akuyenda molunjika kuchokera ku zabwino kupita ku electrode yoyipa, yunifolomu, wandiweyani, komanso womangika bwino zinki wosanjikiza wosanjikiza amakhala pamwamba pa chitoliro chachitsulo.

2) Kutentha-kuviika galvanizing: Chitsulo pamwamba amamizidwa zinki wosungunuka kutsatira kuyeretsa ndi kutsegula. Chigawo chachitsulo cha zinc chimayambira pamwamba pazitsulo chifukwa cha physicochemical reaction pakati pa chitsulo ndi zinki pa mawonekedwe. Poyerekeza ndi galvanizing ozizira, njirayi imapanga mgwirizano wamphamvu pakati pa zokutira ndi gawo lapansi, kupititsa patsogolo kachulukidwe ❖ kuyanika, kulimba, kugwira ntchito mopanda kukonza, komanso kuwononga ndalama.

1) Njira Yopangira: Mayina awo amamveketsa kusiyana kwake. Zinc yomwe imapezeka m'chipinda chozizira imagwiritsidwa ntchito m'mipope yazitsulo zoziziritsa kuzizira, pamene zinki yomwe imapezeka pa 450 ° C mpaka 480 ° C imagwiritsidwa ntchito popangira galvanizing yotentha.

2) Kukhuthala kwa Kupaka: Ngakhale kuthirira kozizira kozizira nthawi zambiri kumatulutsa makulidwe a 3-5 μm okha, zomwe zimapangitsa kuti ntchito ikhale yosavuta, imakhala yosakanizidwa ndi dzimbiri. Mosiyana ndi izi, kuthira kothira kotentha kumapereka makulidwe a 10μm kapena kupitilira apo, komwe kumakhala kosamva dzimbiri kangapo kuposa mizati yowunikira yamalata.

3) Mapangidwe Opaka: Chophimba ndi gawo lapansi zimasiyanitsidwa ndi wosanjikiza wonyezimira wonyezimira mu galvanizing yotentha. Komabe, chifukwa chophimbacho chimapangidwa kwathunthu ndi zinki, zomwe zimapangitsa kuti yunifolomu ikhale ndi ma pores ochepa, zomwe zimapangitsa kuti zisawonongeke, izi zimakhala ndi zotsatira zochepa pa kukana kwake kwa dzimbiri. Mosiyana ndi izi, kutsekemera kozizira kumagwiritsa ntchito zokutira zopangidwa ndi maatomu a zinki ndi njira yomatira yokhala ndi ma pores ambiri, zomwe zimapangitsa kuti zisawonongeke ndi dzimbiri.

4) Kusiyana kwa Mtengo: Kupanga galvanizing otentha-kuviika kumakhala kovuta komanso kovuta. Chifukwa chake, makampani ang'onoang'ono okhala ndi zida zakale nthawi zambiri amagwiritsa ntchito galvanizing yozizira, zomwe zimapangitsa kuti mtengo wake ukhale wotsika kwambiri. Akuluakulu, okhazikika opangira malata otentha nthawi zambiri amakhala ndi mphamvu zowongolera bwino, zomwe zimapangitsa kuti pakhale zokwera mtengo.

Anthu ena anganene kuti ngakhale akudziwa kusiyana kwa galvanizing ya dip-dip ndi galvanizing ya dip-dip, sangadziwebe kusiyana kwake. Izi ndi njira zopangira zomwe siziwoneka ndi maso. Nanga bwanji ngati wamalonda wosaona mtima agwiritsa ntchito malata oziziritsa m’malo mogwiritsa ntchito malata a m’madzi otentha? Kunena zoona, palibe chifukwa chodera nkhawa. Cold dip galvanizing ndikutentha-kuviika galvanizingndizosavuta kusiyanitsa.

Malo okhala ndi malata ozizirirapo amakhala osalala, makamaka obiriira, koma ena amakhala otuwa, otuwa motuwa, kapena oyera ndi kunyezimira kobiriwira. Zitha kuwoneka zosawoneka bwino kapena zakuda. Malo okhala ndi malata otentha, poyerekeza, amakhala olimba, ndipo amatha kukhala ndi maluwa a zinki, koma amawoneka owala kwambiri ndipo nthawi zambiri amakhala oyera ngati siliva. Samalani kusiyana kumeneku.
