Ngenxa yophuhliso olukhulu/olunzulu lokufuya iinkukhu, abalimi abaninzi beenkukhu bakhethaikheji yeenkukhu ezibeka amaqandaukulima kuba ukulima ngeekheyiji kunezi nzuzo zilandelayo:
(1) Yandisa uxinano lwesitokhwe. Uxinano lweekheji zenkukhu ezinemilinganiselo emithathu lungaphezulu ngokuphindwe kathathu kunolweekheji ezisicaba, kwaye iinkukhu ezingaphezu kwe-17 ezinokuzalela zinokukhuliswa ngemitha yesikwere nganye;
(2) Gcina ukutya. Iinkukhu zigcinwa kwiikheyiji, ubungakanani bokuzilolonga buyancipha, ukusetyenziswa kwamandla kuncinci, kwaye inkunkuma yezinto ezisetyenzisiweyo iyancipha. Ukusetyenziswa kokufakelwa kwamaqanda ngokwenziwa kunokunciphisa umlinganiselo weenkukhu;
(3) Iinkukhu azichukumisi ilindle, nto leyo enceda ekuthinteleni ubhubhane kwimihlambi;
(4) Amaqanda acocekile, nto leyo enokugxotha amaqanda ngaphandle kwendlwana.
Nangona kunjalo, abalimi abaninzi abayazi iteknoloji yokucubungulaiikheji zenkukhuBangazikhetha njani iikheji zeenkukhu ezisemgangathweni kwaye zihlala ixesha elide? Kwizixhobo zokukhulisa iinkukhu ngokuzenzekelayo, ukukhetha iikheji zeenkukhu kubaluleke ngakumbi xa kudibana ngqo neenkukhu.Okwangoku, kukho iintlobo ezine zeekheji ezithengiswayo kubafuyi beenkukhu abanokukhetha kuzo:
1. I-galvanized ebandayo.
I-cold galvanizing, eyaziwa ngokuba yi-electrogalvanizing, inomaleko obhityileyo we-galvanizing. Iingenelo ze-cold galvanizing ngumphezulu ogudileyo kunye nokukhanya okuphezulu; nangona kunjalo, isetyenziswa ngokubanzi iminyaka emi-2-3 ukugqwala kwaye inobomi beminyaka emi-6-7. I-cold galvanizing inokwahlulwahlulwa ibe yi-galvaning Color zinc okanye i-white zinc, njl.njl., isiphumo siyafana.
2. Ukufaka i-galvanizing eshushu.
I-hot-dip galvanizing, eyaziwa ngokuba yi-hot-dip galvanizing, ubukhulu bomaleko we-galvaning ngokubanzi bungaphezulu kwama-80μI-m kufuneka ithathwe njengefanelekileyo, ngokubanzi ayilula ukuyigqwala, inokumelana nokugqwala okuphezulu, ngokubanzi ingasetyenziswa iminyaka eli-15 ukuya kwengama-20, kodwa ingxaki kukuba i-galvanizing echibini le-galvanizing ayinakulinganiswa, nto leyo ebangela ukuba kubekho ii-burrs ezininzi, nto leyo efuna ukucutshungulwa ngesandla kwinqanaba elilandelayo.Iikheji zenkukhu ezifakwe ngentsimbi eshushuzezona zikhetho zokuqala zokulima ngokuzenzekelayo, kodwa ixabiso ngokubanzi liphezulu kunezinye.
3. Futha ihoko yenkukhu.
Ingubo yomgubo ifunxwa kwikheyiji ngokutsalwa kombane ongashukumiyo onamandla aphezulu, okwenza ifilimu ye-phosphating engangeni mhlwa phakathi kwekheyiji yenkukhu kunye nengubo, kodwa ikheyiji yenkukhu etshiziweyo inamathuba amaninzi okunamathela kumgquba wenkukhu, kwaye akuyi kuba lula ixesha elide. Kulula ukuguga nokuwa. Olu hlobo lwekheyiji yenkukhu aluqhelekanga kwimarike, kwaye imakethi incinci.
4. Ikheji yenkukhu ye-aluminium alloy ye-zinc.
Ucingo lwe-alloy lwe-zinc-aluminium lusetyenziselwa ukuwelda ngokuthe ngqo, kwaye akukho mfuneko yokucubungula okungakumbi kwinqanaba lokugqibela. Iimfuneko zokuwelda kolu hlobo lwe-mesh yekheji yenkukhu ziphezulu kakhulu. Ukuba ukuwelda akulunganga, amalungu e-solder aya kugqwala. Ukuba inkqubo icwangcisiwe kakuhle, ubomi benkonzo ngokubanzi buya kufikelela kwiminyaka engaphezu kwe-10. Uninzi lwezixhobo ezingenisiweyo zisebenzisa olu hlobo lwe-mesh.
Ngokuphathelele ukuqina, i-hot-dip galvanizing > i-zinc-aluminium alloy > i-spray > i-cold galvanizing.
Silandele siza kuhlaziya ulwazi lokufuya.
