Umehluko phakathi kuka-304 no-316 insimbi engagqwali

Ekuthengeni imikhiqizo yensimbi engagqwali, amagama avamile ensimbi engenasici alandelwa izinombolo ezingu-304 noma ezingu-316, lezi zinombolo ezimbili zibhekisela kumodeli wensimbi engagqwali, kodwa umehluko phakathi kwensimbi engagqwali 304 no-316, kunzima ukusho.Namuhla, sizohlukanisa kokubili ngokuningiliziwe ngombono wokwakheka kwamakhemikhali, ukuminyana, ukusebenza, izinkambu zokufaka isicelo, njll., futhi sikholelwa ukuthi uzoba nokuqonda okucacile kwalezi zinhlobo ezimbili zensimbi engagqwali ngemva kokuzifunda.

#304 insimbi engagqwali # kanye ne-316 insimbi engagqwali i-austenitic stainless steel, umehluko phakathi kwalokhu okubili ekwakhekeni kwamakhemikhali uthi: 316 insimbi engagqwali ithuthukisa i-nickel (Ni) ngokunciphisa okuqukethwe kwe-chromium (Cr), futhi inyusa u-2% -3% we-molybdenum (Mo ), lesi sakhiwo sithuthukisa kakhulu ukumelana nokugqwala nokumelana nokugqoka kwensimbi engagqwali, ngakho ukusebenza kwe-316 insimbi engagqwali kungcono kune-304 insimbi engagqwali.

Okulandelayo umehluko phakathi kuka-304 no-316:

1. Izithako

Ukwakhiwa kwensimbi engagqwali engu-304 yakhiwe nge-chromium engu-18% kanye ne-nickel engu-8%;Ngaphezu kwe-chromium ne-nickel, insimbi engagqwali engu-316 nayo ine-molybdenum elinganiselwa ku-2%.Izingxenye ezihlukene nazo zizenza zihluke ekusebenzeni.

2. Ukuminyana

Ukuminyana kwensimbi engagqwali engu-304 kungu-7.93g/cm³, ukuminyana kwensimbi engagqwali engu-316 kungu-7.98g/cm³, futhi ukuminyana kwensimbi engagqwali okungu-316 kungaphezulu kwalokho kwensimbi engagqwali engu-304.

3. Ukusebenza okuhlukile:

I-elementi ye-molybdenum equkethwe ku-316 insimbi engagqwali iyenza ibe nokumelana nokugqwala okuhle kakhulu, kwezinye izinto ezine-acidic, izinto ze-alkaline, kodwa futhi zibekezelela kakhudlwana, ngeke zigqwale.Ngakho-ke, ukumelana nokugqwala kwensimbi engagqwali engu-304 kungcono ngokwemvelo kunaleyo yensimbi engagqwali engu-316.

4. Izinhlelo zokusebenza ezehlukene:

Insimbi engagqwali engu-304 kanye nensimbi engagqwali engu-316 yizinto zebanga lokudla, kodwa ngenxa yokuthi i-316 inokumelana nokugqwala okungcono kanye nokumelana ne-asidi ne-alkali, izosetshenziswa kakhulu kweminye imishini yezokwelapha nakweminye imikhakha, kuyilapho i-304 insimbi engagqwali isetshenziswa kakhulu ekhishini, njenge njengama-tableware, i-kitchenware, i-stainless steel countertops nokunye.

5. intengo ihlukile:

Ukusebenza kwensimbi engagqwali engu-316 kuphakeme kakhulu, ngakho intengo ibiza kakhulu kunensimbi engagqwali engu-304.

Laba bobabili banezici zabo siqu, futhi indlela yokukhetha incike ekufuneni kwangempela.Nakuba insimbi engagqwali engu-304 ingenakho ukusebenza okuphezulu kwe-316, ukusebenza kwayo kwanele ukuhlangabezana nezidingo zansuku zonke, futhi izindleko zayo zibiza kakhulu, ngakho-ke zibiza kakhulu.Uma kunesidingo esiphezulu sokusetshenziswa, khona-ke insimbi engagqwali engu-316 ingakhethwa ukuze ihlangabezane kangcono nezidingo zomcimbi.

Fingqa izici zokusebenza ezimbili, insimbi engagqwali 304 ukumelana ne-asidi, ukumelana ne-alkali, ukuminyana okuphezulu, ukupholisha ngaphandle kwamabhamuza, ukuqina okuphezulu, ukusebenza kahle kokucubungula;Ngaphezu kwezici zokusebenza zensimbi engagqwali engu-304, insimbi engagqwali engu-316 iphinde imelane nokugqwala okukhethekile okuphakathi, okungathuthukisa ukumelana nokugqwala kumakhemikhali e-hydrochloric acid nolwandle, futhi kuthuthukise ukumelana nokugqwala kusixazululo se-brine halogen.
