Namuhla, insimbi engagqwali isetshenziswa kakhulu ezimpilweni zethu, kusukela emishinini yasemkhathini kuya emabhodweni namapani. Namuhla, sizokwabelana ngezinto ezijwayelekile zensimbi engagqwali 304 kanye ne-316.
Umehluko phakathi kuka-304 no-316
304 kanye ne-316 ngamazinga aseMelika. 3 imele 300 uchungechunge steel. Izinombolo ezimbili zokugcina ziyizinombolo ze-serial. 304 Uhlobo lwesiShayina luyi-06Cr19Ni9 (luqukethe ngaphansi kuka-0.06% C, ngaphezu kuka-19% we-chromium kanye ne-nickel engaphezu kuka-9%); 316 Uphawu lwesiShayina luyi-06Cr17Ni12Mo2 (iqukethe ngaphansi kuka-0.06% C, ngaphezu kuka-17% we-chromium, ngaphezu kuka-12% we-nickel kanye ne-molybdenum engaphezu kuka-2%.
Kukholakala ukuthi singabona futhi kusukela kumkhiqizo ukuthi ukwakheka kwamakhemikhali kwe-304 no-316 kuhlukile, futhi umehluko omkhulu obangelwa ukwakheka okuhlukile ukuthi ukumelana ne-asidi nokumelana nokugqwala kuhlukile. Uma kuqhathaniswa nesigaba se-304, isigaba se-316 sinokukhuphuka kwe-nickel ne-nickel, ngaphezu kwalokho, i-molybdenum ne-molybdenum yengezwa. Ukwengeza i-nickel kungathuthukisa ukuqina, izakhiwo zemishini kanye nokumelana ne-oxidation yensimbi engagqwali. I-Molybdenum ingathuthukisa ukugqwala komkhathi, ikakhulukazi ukugqwala kwe-atmospheric okuqukethe i-chloride. Ngakho-ke, ngaphezu kwezici zokusebenza zensimbi engagqwali engu-304, insimbi engagqwali engu-316 iphinde imelane nokugqwala kwemidiya ekhethekile, engathuthukisa ukumelana nokugqwala kwamakhemikhali e-hydrochloric acid nolwandle, futhi ithuthukise ukumelana nokugqwala kwesixazululo se-brine halogen.
Ibanga lesicelo lika-304 kanye no-316
I-304 insimbi engagqwali isetshenziswa kabanzi, njengezitsha zasekhishini kanye ne-tableware, umhlobiso wezakhiwo, imboni yokudla, ezolimo, izingxenye zemikhumbi, igumbi lokugezela, izingxenye zemoto, njll.
Intengo ye-316 yensimbi engagqwali iphakeme kune-304. Uma iqhathaniswa ne-304, i-316 insimbi engagqwali inokumelana okuqinile kwe-asidi nokuzinza okungcono. I-316 insimbi engagqwali isetshenziswa kakhulu embonini yamakhemikhali, udayi, ukwenza iphepha, i-acetic acid, umanyolo nezinye izinto zokukhiqiza, imboni yokudla kanye nezindawo ezisogwini, kanye nemikhiqizo enezidingo ezikhethekile zokumelana nokugqwala kwe-intergranular.
Ukuphila kwansuku zonke, insimbi engagqwali engu-304 ingahlangabezana nezidingo zethu, kanti i-304 iphinde ibe yinsimbi engagqwali ehlangabezana ngokugcwele nezinga lokudla.
