Uyini umehluko phakathi kuka-304 no-201 insimbi engagqwali?

Umehluko Wendawo
Kunomehluko ocacile phakathi kwalokhu okubili okuvela phezulu. Uma ukuqhathanisa, 201 impahla ngenxa izakhi manganese, ngakho le nto yensimbi engagqwali zokuhlobisa tube surface umbala buthuntu, 304 impahla ngenxa yokungabikho izakhi manganese, ngakho ubuso kuyoba bushelelezi futhi elikhanyayo. Umehluko kusuka ebusweni kuqhathaniswa nohlangothi olulodwa, ngoba ithubhu yensimbi engagqwali yefekthri izoba ngemva kokwelashwa okungaphezulu, ngakho le ndlela ifaneleka kuphela ukuhlukaniswa kwensimbi engagqwali okungakacutshungulwa.

 

Umehluko Wokusebenza

201 insimbi engagqwaliukumelana nokugqwala, ukumelana ne-asidi kanye ne-alkali kubuthakathaka uma kuqhathaniswa304 insimbi engagqwali, futhi 201 ubulukhuni bensimbi engagqwali bungaphezu kuka-304 insimbi engagqwali.

Ifomula yamakhemikhali ka-201 ithi 1Cr17Mn6Ni5, ifomula yamakhemikhali engu-304 ithi 06Cr19Ni10. umehluko osobala kakhulu phakathi kwazo okuqukethwe okuhlukile kwezakhi ze-nickel ne-chromium, u-304 uyi-nickel engu-19 ye-chromium 10, kuyilapho u-201 eyi-nickel engu-17 chromium 5. Ngenxa yezinhlobo ezi-2 zensimbi engagqwali yepayipi lokuhlobisa okuqukethwe kwe-nickel kuhlukile, ngakho-ke ukumelana nokugqwala okungu-201, ukumelana ne-asidi ne-alkali kuhle kakhulu kuno-304. Okuqukethwe kwekhabhoni okungu-201 kungaphezulu kuka-304, ngakho-ke u-201 ulukhuni futhi ubrittle kuno-304 , kuyilapho i-304 inokuqina okungcono, ngakho ifaneleka kakhulu ukuthi isetshenziswe kamuva.

Manje kukhona ainsimbi engagqwaliukuhlolwa kwe-potion emakethe, inqobo nje uma amaconsi ambalwa ezokwazi ukuhlukanisa ukuthi iyiphi insimbi engagqwali ngemizuzwana embalwa, umgomo uwukwenza izakhi eziqukethwe kundaba ngokuhlonza into ebhodweni ukuze ikhiqize ukusabela kwamakhemikhali. izinto ezinemibala. Lokhu kungahlukanisa ngokushesha phakathi kwezinto ezingama-304 nezingu-201.
Umehluko wohlelo lokusebenza
Ngenxa yezakhiwo zamakhemikhali ezihlukene, i-201 ijwayele ukugqwala kunensimbi engagqwali engama-304. Ngakho-ke, i-201 ngokuvamile ifaneleka kuphela ukusetshenziswa endaweni eyomile yokwakha kanye nomhlobiso wezimboni. Futhi i-304 ngenxa yokumelana nokugqwala, ukumelana ne-asidi ne-alkali nezinye izakhiwo kunezinzuzo ezinkulu, ukumbozwa kwesicelo kubanzi, okujwayelekile, futhi akugcini nje kuphela ekuhlobiseni izicelo.

Umehluko Wamanani

304 insimbi engagqwali ngenxa yezinzuzo zokusebenza kuzo zonke izici, ngakho-ke kubiza kakhulu uma kuqhathaniswa nensimbi engagqwali engu-201.

 

Bona indlela elula ye-304 kanye ne-201 ye-stainless steel plate

I-304 insimbi engagqwali ngenxa yokumelana kwayo nokugqwala okuhle kakhulu ivame ukusetshenziswa ongqimbeni lwangaphakathi (okungukuthi, ukuthintana ngqo namanzi), insimbi engagqwali engu-201 ngenxa yokungagqwala okungekuhle, ayikwazi ukusetshenziswa ongqimbeni lwangaphakathi, oluvame ukusetshenziswa ongqimbeni lwangaphandle lwe-corrosion. ithangi le-insulation. Kodwa i-201 ishibhile kune-304, evame ukusetshenziswa abanye osomabhizinisi abangenangqondo abazenza i-304, ne-201 yensimbi engagqwali eyenziwe ngensimbi engenasici impilo yesevisi yethangi yamanzi ifushane kakhulu, ngokuvamile iminyaka engu-1-2 ingagqwala ngamanzi, ishiya umsebenzisi izingozi zokuphepha.

Indlela elula yokubona izinto ezimbili:
1. I-304 ne-201 insimbi engagqwali esetshenziswa ethangini lamanzi lensimbi engagqwali, indawo engaphezulu ngokuvamile ilula. Ngakho sikhomba indlela ngeso lenyama, ukuthinta ngesandla. Iso elinqunu ukubona insimbi engagqwali engu-304 inokucwebezela okuhle kakhulu, ukuthinta ngesandla kubushelelezi kakhulu; Insimbi engagqwali engu-201 imnyama ngombala, ayibenyezi, ukuthinta kunomuzwa ongemuhle ongasheleli. Ngaphezu kwalokho, isandla sizoba manzi ngamanzi, ngokulandelana, thinta izinhlobo ezimbili zepuleti yensimbi engagqwali, uthinte amabala amanzi ku-304 plate handprints kulula ukusula, 201 akulula ukusula.
2. Sebenzisa umshini wokugaya olayishwe isondo lokugaya ngokusandeni ngobumnene izinhlobo ezimbili zebhodi, ukunisa amabhodi angama-201 kuzinhlansi ezinde, ezishubile, eziningi, futhi okuphambene nalokho, izinhlansi zebhodi ezingu-304 zifushane, zicolekile, zincane. Amandla esihlabathi kumele abe lula, futhi izinhlobo ezi-2 zamandla esihlabathi aziguquguquki, kulula ukuzihlukanisa.
3. ngensimbi engagqwali pickling ukhilimu ayenamekwe 2 izinhlobo insimbi engagqwali plate. Ngemuva kwemizuzu emi-2, bheka ushintsho lombala wensimbi engagqwali ekunambeni. Umbala omnyama ngo-201, umhlophe noma ungashintshi umbala ku-304.
