Ungakhetha kanjani ikheji lenkukhu elifanele lokubeka amaqanda?

Ngokuthuthuka okukhulu/okujulile kokufuya izinkukhu, abalimi bezinkukhu abaningi bakhethaikheji lezinkukhu ezibeka amaqandaukulima ngoba ukulima ngezikheji kunezinzuzo ezilandelayo:

(1) Khulisa ubuningi bezinkukhu. Ubuningi bezinkukhu ezinezinhlangothi ezintathu buphakeme ngokuphindwe kathathu kunobamakheji ayisicaba, futhi izinkukhu ezingaphezu kuka-17 ezizalelayo zingakhuliswa ngemitha yesikwele;

(2) Gcina ukudla. Izinkukhu zigcinwa ezikhejini, inani lokuzivocavoca liyancipha, ukusetshenziswa kwamandla kuncane, futhi ukuchithwa kwezinto kuyancipha. Ukuqaliswa kokuzalisa ngokwenziwa kunganciphisa inani lamaqhude;

(3) Izinkukhu azithinti indle, okuyinto ekhuthaza ukuvimbela ubhubhane emihlambini;

(4) Amaqanda ahlanzekile, okungasusa amaqanda ngaphandle kwesidleke.

Kodwa-ke, abalimi abaningi abazi ubuchwepheshe bokucubungulaamakheji enkukhu. Bangazikhetha kanjani izikheji zezinkukhu ezinekhwalithi enhle futhi ezihlala isikhathi eside? Emishinini yokukhulisa izinkukhu ngokuzenzakalela, ukukhetha izikheji zezinkukhu kubaluleke kakhulu njengokuxhumana ngqo nezinkukhu.Njengamanje, kunezinhlobo ezine zamakheji emakethe zabafuyi bezinkukhu abangakhetha kuzo:

1. I-galvanized ebandayo.

I-cold galvanizing, eyaziwa nangokuthi i-electrogalvanizing, inesendlalelo esincane se-galvaning. Izinzuzo ze-cold galvanizing ubuso obubushelelezi nokukhanya okuphezulu; noma kunjalo, ngokuvamile isetshenziswa iminyaka engu-2-3 ukugqwala futhi inokuphila kweminyaka engu-6-7. I-cold galvanizing ingahlukaniswa futhi ibe yi-galvaning Color zinc noma i-white zinc, njll., umphumela uyafana.

2. Ukushisa nge-galvanizing.

Ukushisa nge-galvanizing, okwaziwa nangokuthi ukushisa nge-galvanizing, ubukhulu besendlalelo se-galvaning ngokuvamile bungaphezu kwama-degrees angu-80μI-m okufanele ibhekwe njengefanelekile, ngokuvamile akulula ukugqwala, ukumelana nokugqwala okuphezulu, ngokuvamile ingasetshenziswa iminyaka eyi-15 kuya kwengama-20, kodwa ububi ukuthi i-galvanizing echibini le-galvanizing Uneven, okuholela kuma-burrs amaningi, okudinga ukucutshungulwa ngesandla esigabeni esilandelayo.Amakheji enkukhu afakwe ngogesi ashisayoyizona ezikhethwa kuqala ekulimeni okuzenzakalelayo, kodwa intengo ngokuvamile iphakeme kunezinye.

3. Futha ihhoko lezinkukhu.

Isembozo sempuphu sinamathela ekhejini ngokukhanga kukagesi oqinile onamandla aphezulu, okwenza ifilimu ye-phosphating engagqwali kakhulu phakathi kwekheji lenkukhu kanye nesembozo, kodwa ikheji lenkukhu elifuthwe cishe linamathela kakhulu emqubeni wenkukhu, futhi ngeke kube lula isikhathi eside. Kulula ukuguga nokuwa. Lolu hlobo lwekheji lenkukhu aluvamile emakethe, futhi imakethe incane kakhulu.

4. Ikheji lenkukhu eliyingxubevange ye-zinc aluminium.

Ucingo lwe-alloy lwe-zinc-aluminium lusetshenziselwa ukushisela ngqo, futhi akukho okunye okudingekayo esigabeni esilandelayo. Izidingo zokushisela zalolu hlobo lwe-mesh yekheji lenkukhu ziphakeme kakhulu. Uma ukushisela kungalungile, amalunga e-solder azogqwala. Uma inqubo iqondiswe kahle, impilo yesevisi ngokuvamile izofinyelela eminyakeni engaphezu kweyi-10. Iningi lemishini engenisiwe isebenzisa lolu hlobo lwe-mesh.

Ngokuphathelene nokuqina, i-hot-dip galvanizing > i-zinc-aluminium alloy > i-spray > i-cold galvanizing.

Silandele sizobuyekeza ulwazi lokuzalanisa.
