Ngemva kokubona lesi sihloko, umhleli waqagela ukuthi abangani abaningi bazomangala. Zingagqwala kanjani izinkomishi zamanzi zensimbi engagqwali? Insimbi engagqwali? Insimbi engagqwali ayigqwali yini? Ikakhulukazi abangani abangasebenzisi izinkomishi ze-thermos zensimbi engagqwali nsuku zonke bazomangala nakakhulu. Namuhla ngizokwabelana nawe kafushane ukuthi kungani izinkomishi zensimbi ezingenasici ze-thermos zigqwala?
Insimbi engagqwali yitemu elivamile lamanye ama-alloy steels akhethekile. Ibizwa ngensimbi engagqwali ngoba izinto zensimbi zale alloy ngeke zigxume emoyeni, izinkomishi zamanzi, isitimu nolunye uketshezi oluneasidi ebuthakathaka. Kodwa-ke, izinsimbi ezingenasici ezihlukene zizogqwala ngemva kokufinyelela izimo zazo ze-oxidation. Ingabe lokhu akuphikisani negama? Cha, igama elithi insimbi engagqwali liwukubonakaliswa kwezakhiwo nezici zezinto zensimbi. Isibonelo, igama langempela le-304 insimbi engagqwali njengoba sonke sazi ukuthi i-austenitic stainless steel. Ngaphezu kwensimbi engagqwali ye-austenitic, kukhona nensimbi engagqwali ye-ferrite ne-martensitic. njll. Umehluko ubangelwa ikakhulukazi umehluko wokuqukethwe kwe-chromium nokuqukethwe kwe-nickel kokokusebenza, kanye nomehluko wokuminyana komkhiqizo ngokwawo.
Abangane abanomkhuba wokuqaphelisisa ekuphileni kwansuku zonke bazothola ukuthi ngokuyisisekelo akukho ukugqwala ezintweni zensimbi engagqwali ezinezindawo ezibushelelezi ikakhulukazi, kodwa eminye imikhiqizo yensimbi engagqwali enezindawo ezimahhadlahhadla nemigodi izogqwala emigodini. Lokhu kungenxa yokuthi i-surface yensimbi engagqwali ibushelelezi, kuzoba nongqimba lwamanzi anamathelayo. Lokhu kufakwa kwamanzi kuhlukanisa ukuqoqwa komswakama. Lezo zingqimba zamanzi ezilimele ezinemigodi phezulu zizokwenza ukuthi umswakama emoyeni unqwabelane, kubangele i-oxidation nokugqwala. Isimanga.
Okungenhla kuyindlela yokuthi insimbi engagqwali igqwale, kodwa akuzona zonke izinto zensimbi ezingenasici ezizokhipha i-oxidize futhi zigxume ngaphansi kwalezi zimo ezingenhla. Isibonelo, insimbi engagqwali engu-304 okukhulunywe ngayo manje kanye nensimbi engagqwali engu-316 eyaziwa kakhulu akuvamile ukuba nayo le nto. Imikhiqizo yensimbi engagqwali ebuye ibizwe ngensimbi engagqwali, efana ne-201 stainless steel kanye ne-430 stainless steel, izovela.
Lapha sizogxila ezintweni ezintathu ezivame ukusetshenziswa ekukhiqizeni izinkomishi zamanzi zensimbi engagqwali emakethe: 201 insimbi engagqwali, 304 insimbi engagqwali kanye 316 insimbi engagqwali. Esihlokweni esandulele, umhleli ukhulume ukuthi okwamanje i-201 insimbi engagqwali ayikwazi ukusetshenziswa njengento yokukhiqiza yezinkomishi zamanzi zensimbi engagqwali ngoba ayikwazi ukuhlangabezana nezidingo zebanga lokudla kanye nokuqukethwe kwesici kumpahla kudlula. Lokhu empeleni ngandlela thize. Okwakushiwo umhleli ngaleso sikhathi ukuthi insimbi engagqwali engu-201 ayikwazi ukusetshenziswa njengento yodonga lwangaphakathi lwenkomishi yamanzi yensimbi engagqwali. Njengoba i-201 insimbi engagqwali ayikwazi ukufinyelela ebangeni lokudla, ayikwazi ukuxhumana namanzi okuphuza isikhathi eside.
Abantu abaphuza amanzi afakwe ngensimbi engagqwali engu-201 isikhathi eside bazobhekana nokungakhululeki ngokomzimba futhi kuthinte impilo yabo. Kodwa-ke, njengoba ithangi langaphakathi lenkomishi ye-thermos yensimbi engenasici ine-double-layered, udonga lwangaphandle ngeke luvezwe emanzini, ngakho-ke luye lwasetshenziswa abakhiqizi abaningi njengento yokukhiqiza yodonga lwangaphandle lwenkomishi yamanzi yensimbi engagqwali. Kodwa-ke, umphumela we-anti-oxidation wensimbi engagqwali engu-201 ungaphansi kakhulu kwalowo wensimbi engagqwali engu-304, futhi awuzweli kwisifutho sikasawoti. Umphumela umpofu, yingakho ngemva kokusebenzisa izinkomishi ze-thermos ezisetshenziswa abangani abaningi isikhathi esithile, udonga lwangaphakathi lwethangi elingaphakathi ngeke lugqwale, kodwa kunalokho udonga lwangaphandle luzogqwala ngemva kokuba upende uqhuma, ikakhulukazi ongaphandle. udonga olunamazinyo.
