Chingwe cha waya chopangidwa ndi chitsulo cholimba ndi chingwe cha waya chosapanga dzimbiri: kusanthula kwaukadaulo kwa momwe amagwirira ntchito, momwe amagwiritsidwira ntchito komanso momwe amasankhidwira.

Zingwe za waya zachitsulo, monga zida zofunika kwambiri zonyamula katundu ndi zotumizira, zimagwiritsidwa ntchito kwambiri pa zomangamanga, mayendedwe, uinjiniya wapamadzi, ndi mafakitale. Pakati pa mitundu yambiri, Chingwe cha Waya cha Chitsulo Chopangidwa ndi KanasonkhezerekaZingwe za waya zosapanga dzimbiri ndi zitsulo zosapanga dzimbiri ndi njira ziwiri zazikulu zomwe nthawi zambiri zimayerekezeredwa posankha zinthu zaukadaulo chifukwa cha kukana dzimbiri komanso mphamvu zake zapadera zamakina. Nkhaniyi ipereka kusanthula kwaukadaulo koyerekeza kwa ziwirizi kuchokera kumitundu yosiyanasiyana, kuphatikiza sayansi ya zida, mphamvu zamakina, njira zotsutsana ndi dzimbiri, ndi zachuma, ndikupereka malingaliro osankha zinthu.

I. Kusanthula kwa Njira Yotetezera Zinthu ndi Kudzimbiri

1. Chingwe cha Waya cha Chitsulo Chopangidwa ndi Galvanized

Kapangidwe ka Zinthu: Chitsulo cha kaboni wambiri ngati maziko, chophimbidwa ndi zinc yeniyeni kapena zinc-iron alloy kudzera mu hot-dip galvanizing kapena electro-galvanizing processes.

Njira Yotetezera Kudzimbiri: Zinc wosanjikiza umateteza chitsulo cha kaboni kuti chisachite dzimbiri kudzera mu njira yotetezera anode. Pamene pamwamba pa chingwe cha waya pawonongeka ndipo zinthu zapansi pa nthaka zawonekera, zinc yogwira ntchito imagwira ntchito ngati anode, motero imateteza chitsulo chosagwira ntchito (cathode).

Makhalidwe Ogwira Ntchito:

Kukana Kudzikundikira: Zabwino, zotsutsana bwino ndi okosijeni ndi chinyezi m'mlengalenga.

Zoletsa: Kukhuthala kwa zinc layer ndi kochepa. Mu chloride (monga madzi a m'nyanja) kapena m'malo okhala ndi asidi/alkali wamphamvu, zinc layer imadyedwa mwachangu. Ikatha, chitsulo choyambira chimadzipitsa msanga.

2. Chingwe cha Waya Chosapanga Chitsulo

Kapangidwe ka Zinthu: Makamaka chitsulo chosapanga dzimbiri cha austenitic. Mitundu yomwe imagwiritsidwa ntchito kwambiri ndi iyi:

AISI 304: Ili ndi 18% chromium ndi 8% nickel, yoyenera malo owononga. AISI 316: Ili ndi chromium, nickel, ndi molybdenum (Mo) yowonjezera.

Njira Yotetezera Kudzimbiri: Chromium (Cr) mu chitsulo chosapanga dzimbiri imakumana ndi mpweya mumlengalenga kapena m'madzi kuti ipange filimu yopyapyala kwambiri, yokhuthala, komanso yowonekera bwino ya chromium-rich oxide passive film pamwamba. Filimuyi ndi yopanda mankhwala ambiri komanso imadzichiritsa yokha, motero imaletsa kuwonongeka kwa chitsulo ndi dzimbiri.

Makhalidwe Ogwira Ntchito:

Kukana Kudzikundikira: Zabwino Kwambiri. Makamaka chitsulo chosapanga dzimbiri cha 316 (cha mtundu wa m'madzi), chifukwa cha kuwonjezera kwa molybdenum, chakhala ndi mphamvu yolimbana ndi dzimbiri komanso dzimbiri, zomwe zimagwira ntchito bwino kwambiri m'malo okhala ndi mankhwala komanso m'malo okhala ndi zinthu zosiyanasiyana.

Zoletsa: Kudula mtengo kwambiri, komanso kusweka kwa stress corrosion (SCC) kungachitikebe m'malo otentha kwambiri a chloride.

II. Kuyerekeza kwa Katundu wa Makina ndi Makhalidwe Otopa

1. Mphamvu Yokoka

Chingwe Chopangidwa ndi Kanasonkhezereka: Chitsulo choyambira nthawi zambiri chimakhala chokokedwa ndi chitsulo cha kaboni wambiri, chokhala ndi mphamvu yokoka kwambiri. Mphamvu yake yosweka nthawi zambiri imakhala yokwera kuposa chingwe cha chitsulo chosapanga dzimbiri cha mtundu womwewo.

Chingwe cha Chitsulo Chosapanga Dzimbiri: Chitsulo chosapanga dzimbiri cha Austenitic (304/316) chingathenso kukhala ndi mphamvu zambiri pambuyo pochilimbitsa mu ntchito yozizira, koma nthawi zambiri chimakhala chotsika pang'ono kuposa chingwe cha waya chachitsulo cholimba cha mtundu womwewo. Komabe, pansi pa kutentha kapena malo enaake, chingwe chachitsulo chosapanga dzimbiri chimakhala ndi mphamvu yosunga.

2. Kutopa Kwambiri
Kutopa nthawi zonse ndi chizindikiro chachikulu cha kulimba kwa chingwe cha waya wachitsulo.

Chingwe Chopangidwa ndi Kanasonkhezereka: Njira yopangira ma galvanizing ingakhudze kapangidwe ka mkati mwa waya wachitsulo pamlingo winawake, koma ponseponse, mphamvu yake yotopa ndi yabwino. Komabe, zinc wosanjikiza ikhoza kuchotsedwa chifukwa cha kukangana kwa nthawi yayitali, zomwe zimafulumizitsa dzimbiri lamkati ndikuchepetsa nthawi yotopa.

Chingwe cha Chitsulo Chosapanga Dzimbiri: Mu malo osawononga, mphamvu yake yogwira ntchito yotopa imafanana ndi ya chingwe chachitsulo champhamvu kwambiri. Mu malo owononga, chitsulo chosapanga dzimbiri chimaletsa kufalikira kwa ming'alu yaying'ono mu mawaya achitsulo chifukwa cha dzimbiri, zomwe zimapangitsa kuti dzimbiri likhale ndi nthawi yayitali yogwira ntchito yotopa kuposa zingwe za waya zachitsulo zomangiriridwa.

III. Mfundo Zosankha Zinthu Zaukadaulo ndi Malangizo Ogwiritsira Ntchito

Njira yosankha zinthu mwaukadaulo iyenera kukhala yosiyana kwambiri pakati pa magwiridwe antchito, malo okhala, nthawi yogwiritsira ntchito, ndi mtengo wake.

1. Kuwunika Kudzikundikira kwa Zachilengedwe (Chinthu Chofunikira)

2. Zofunika Kuganizira Pakapangidwe ka Nyumba ndi Kusamalira

Kukonza: Zingwe zosapanga dzimbiri sizimafuna kukonza nthawi zonse m'malo ovuta, zomwe zimachepetsa mtengo wonse wa umwini (TCO).

Zofunikira pa MphamvuNgati ntchitoyo ili ndi zofunikira zonse kuti ikhale yolimba komanso yolimba pang'ono, zingwe za waya zachitsulo zolimba kwambiri ziyenera kukhala chisankho choyamba.

Mitundu Yogwiritsira Ntchito:

Kukweza ndi kukweza: Zingwe za waya zachitsulo zolimba kwambiri zimagwiritsidwa ntchito nthawi zambiri, zomwe zimagogomezera chitetezo, kulimba, komanso kusunga ndalama.

Kumangirira ndi zingwe (monga milatho, nsanja za m'mphepete mwa nyanja): Kwambiri Waya Wosapanga Dzimbiri Wosagonjetsedwa ndi Dzimbiri Zingwe ziyenera kugwiritsidwa ntchito, zomwe zikusonyeza kukhazikika kwa kapangidwe kake kwa nthawi yayitali komanso zosowa zochepa zosamalira.

3. Kusanthula Zachuma

Ngakhale mtengo wogulira chingwe cha waya wachitsulo cholimba ndi wotsika kwambiri kuposa wa chingwe cha waya chosapanga dzimbiri (nthawi zambiri chimakhala chochepa poyerekeza ndi mtengo wake), m'malo omwe amawononga kwambiri, chingwe cholimba chingafunike kusinthidwa pafupipafupi, zomwe zimapangitsa kuti mtengo wonse ukhale wokwera kwa nthawi yayitali (kuphatikizapo kugula, kusintha, ndi nthawi yopuma) poyerekeza ndi chingwe chachitsulo chosapanga dzimbiri chokwera mtengo. Chifukwa chake, **kusanthula mtengo wa moyo wonse (LCC)** kuyenera kugwiritsidwa ntchito kuti mudziwe njira yomaliza yopezera ndalama.

Mapeto

Chingwe cha waya chachitsulo chopangidwa ndi galvanized ndi njira yogwiritsira ntchito zinthu zosiyanasiyana komanso yotsika mtengo yoyenera malo ambiri a mafakitale ndi mlengalenga, zomwe zimagogomezera mphamvu zambiri komanso mtengo wotsika. Chingwe cha waya chachitsulo chosapanga dzimbiri, kumbali ina, ndi chinthu chogwira ntchito bwino kwambiri chomwe chimapangidwa kuti chisawonongeke ndi malo ovuta, zomwe zimapangitsa kuti chikhale chisankho choyamba chosasinthika, makamaka mu uinjiniya wa m'madzi, uinjiniya wa mankhwala, kukonza chakudya, ndi ntchito zomwe zimafuna kukhazikika kwa nthawi yayitali komanso kukongola. Mainjiniya ayenera kusankha zinthu mwaukadaulo kwambiri kutengera kuwunika kolimba kwa chilengedwe, zofunikira pamakina, komanso kusanthula mtengo wa moyo.
