Ngemva kokuba izindebe ze-thermos “ezibulalayo” zidalulwe, amanani ahluka kakhulu. Ezishibhile zibiza amashumi ama-yuan kuphela, kanti ezibizayo zibiza izinkulungwane zama-yuan. Ingabe izinkomishi ezishibhile ze-thermos ziyizinga eliphansi ngempela? Ingabe izinkomishi ezibizayo ze-thermos zingaphansi kwentela ye-IQ?
Ngo-2018, i-CCTV yadalula izinhlobo eziyi-19 zezinkomishi ze-thermos “ezibulalayo” emakethe. Ngemva kokuthela i-hydrochloric acid enkomishini ye-thermos futhi iyishiye amahora angu-24, amanani eqile e-manganese, nickel nezinsimbi ze-chromium ayengatholwa ku-hydrochloric acid.
Lezi ezintathu ziyizinsimbi ezisindayo. Okuqukethwe kwabo ngokweqile kungaholela ekuvikelekeni okuphansi, ukungezwani komzimba nesikhumba, futhi kubangele umdlavuza. Ziyingozi ikakhulukazi kubantu asebekhulile nasezinganeni, futhi zingabangela i-dysplasia yentuthuko kanye ne-neurasthenia.
Isizathu esenza inkomishi ye-thermos iqukethe lezi zinsimbi ezisindayo yingoba ithangi layo elingaphakathi ngokuvamile lenziwa ngezinto ezintathu ezijwayelekile zensimbi engagqwali, okungu-201, 304 kanye no-316.
I-201 insimbi engagqwali insimbi engagqwali yezimboni ene-chromium ephansi kanye nokuqukethwe kwe-nickel. Kodwa-ke, ijwayele ukugqwala ezindaweni ezinomswakama futhi ijwayele ukugqwala lapho ibhekene nezinto ezine-asidi, ngaleyo ndlela idonse izinsimbi ezisindayo. Alikwazi ukuxhumana nokudla neziphuzo isikhathi eside.
Insimbi engagqwali engu-304 ngokuvamile ibhekwa njengempahla yezinga lokudla futhi ingasetshenziswa ukwenza umugqa wenkomishi ye-thermos; Insimbi engagqwali engu-316 iyinsimbi engagqwali yezinga lezokwelapha, evikeleke kakhulu futhi ekwazi ukumelana nokugqwala.
Ukuze kongiwe izindleko, abanye abahwebi abangathembekile bavame ukukhetha insimbi engagqwali eshibhe kakhulu engu-201 njengomugqa wangaphakathi wenkomishi ye-thermos. Nakuba izinkomishi ezinjalo ze-thermos zingelula ukukhulula izinsimbi ezisindayo lapho zigcwalisa amanzi ashisayo, zilimala kalula lapho zihlangana neziphuzo ezine-asidi namajusi. Ukugqwala, okubangela izinsimbi ezisindayo ngokweqile.
Izindinganiso zikazwelonke ezifanele zikholelwa ukuthi inkomishi ye-thermos efanelekayo ingabiliswa ngesisombululo se-acetic acid esingu-4% imizuzu engu-30 futhi ifakwe amahora angu-24, futhi inani lokufuduka kwe-chromium yensimbi yangaphakathi alidluli ku-0.4 mg/square decimeter. Kungabonakala ukuthi ngisho nezindebe ze-thermos ezisezingeni eliphansi kufanele zihlangabezane nezindinganiso zokukwazi ukubamba ngokuphepha iziphuzo ze-carbonated, kunokuvumela abathengi ukuthi bagcine amanzi ashisayo kuphela.
Kodwa-ke, lezo zilayini zenkomishi ye-thermos ezingafanelekile emakethe zenziwe ngensimbi engagqwali yezinga eliphansi lezinga lezimboni, insimbi engagqwali egqwalile noma insimbi esetshenzisiwe elahliwe, ezolimaza impilo yabantu.
Okubalulekile ukuthi amanani alezi zinkomishi ze-thermos akuyona yonke imikhiqizo eshibhile. Amanye angaphezulu kwama-yuan ayishumi noma angamashumi amabili lilinye, kanti amanye afinyelela kumayuan angamakhulu amabili. Ngokuvamile, ama-yuan angu-100 anele ukuthi amabhizinisi asebenzise izinto eziphephile ukukhiqiza izinkomishi ze-thermos. Ngisho noma zingekho izidingo ezikhethekile zomphumela wokufakelwa, amashumi ama-yuan angakwenza ngokuphelele.
Kodwa-ke, izinkomishi eziningi ze-thermos zihlala zigcizelela ukusebenza kwazo kokushisa okushisayo, zinikeza abathengi inkohliso yokuthi imikhiqizo yabo iphephe ngokuphelele. Lapho sikhetha inkomishi ye-thermos emakethe, kufanele sinake futhi sizame ukukhetha uhlobo oluthile oludumile. Kodwa-ke, kunezinkomishi ze-thermos ezine-SUS304 kanye ne-SUS316 ethangini elingaphakathi.
Ngesikhathi esifanayo, udinga ukubheka ukuthi zikhona yini izimpawu zokugqwala ngaphakathi kwenkomishi ye-thermos, noma ngabe ingaphezulu libushelelezi futhi liyashintshashintsha, noma ngabe kukhona iphunga elingavamile, njll. Ngokuvamile, ithangi elingaphakathi alinakho ukugqwala, indawo ebushelelezi. futhi akukho phunga elingaqinisekisa ngokuyisisekelo ukuthi impahla ngeke igle futhi isanda kukhiqizwa insimbi engagqwali.
Amanani ezinkomishi ze-thermos njengamanje emakethe ahluka kakhulu. Izinkomishi ze-thermos ezishibhe kancane zisebenzisa ubuchwepheshe bokukhipha umsila futhi zinegumbi elifihlekile lomsila ngaphansi ukuze kugcinwe ukushisa, kodwa zithatha isikhala esiningi futhi zinciphisa umthamo wokugcina amanzi.
Izinkomishi ze-thermos ezibiza kakhulu zivame ukususa lo mklamo. Ngokuvamile basebenzisa i-austenitic stainless steel liner elula futhi enamandla (eye-SUS304 insimbi engagqwali). Lolu hlobo lwensimbi engagqwali lulawula okuqukethwe kwe-metallic chromium ku-16% -26%, engakha ifilimu evikelayo ye-chromium trioxide phezulu futhi inokumelana nokugqwala okuqinile.
Kodwa-ke, lezo zinkomishi ze-thermos emakethe ezithengiswa ngaphezu kuka-3,000 kuya ku-4,000 yuan ngayinye ivame ukuba namathangi angaphakathi enziwe nge-titanium alloy. I-insulation effect yale nto ifana neyensimbi engagqwali. Okubalulekile ukuthi iphephe kakhulu, ngoba i-titanium ayibangeli ubuthi bensimbi enzima. Nokho, le ntengo ayidingekile ngempela kubantu abaningi.
Ngokuvamile, izinkomishi eziningi ze-thermos azibhekwa njengentela ye-IQ. Lokhu kuyafana nokuthenga ibhodwe ekhaya. Ibhodwe lensimbi elibiza inqwaba yamadola ucezu alubi ngempela, kodwa amathuba okuhlangana nemikhiqizo yekhwalithi ephansi azokhula. Umkhiqizo onenani eliphezulu kakhulu awuhlangabezani nezidingo zabantu abaningi. Kuhlanganiswe, ukuthenga imikhiqizo enenani lama-yuan ayi-100-200 kuwukukhetha kwabantu abaningi.
