Kodi makapu otsika mtengo a thermos amakhala opanda khalidwe?

Makapu "akupha" a thermos atawululidwa, mitengo idasiyana kwambiri. Zotsika mtengo zimangotengera ma yuan khumi, pomwe zokwera mtengo zimafika masauzande a yuan. Kodi makapu otsika mtengo a thermos amakhala opanda khalidwe? Kodi makapu okwera mtengo a thermos amakhala ndi msonkho wa IQ?

Mu 2018, CCTV idawulula mitundu 19 ya makapu "akupha" a thermos pamsika. Mukathira hydrochloric acid mu kapu ya thermos ndikuisiya kwa maola 24, manganese, faifi tambala ndi zitsulo za chromium zitha kupezeka mu hydrochloric acid.

Izi zitatu ndi zitsulo zolemera. Kuchulukitsitsa kwawo kungayambitse kuchepa kwa chitetezo chamthupi, kufooka kwapakhungu, komanso kuyambitsa khansa. Amawononga makamaka okalamba ndi ana, ndipo angayambitse chitukuko cha dysplasia ndi neurasthenia.

Chifukwa chomwe chikho cha thermos chimakhala ndi zitsulo zolemerazi ndichifukwa thanki yake yamkati nthawi zambiri imapangidwa ndi zida zitatu zosapanga dzimbiri, zomwe ndi 201, 304 ndi 316.

201 chitsulo chosapanga dzimbiri ndi chitsulo chosapanga dzimbiri chokhala ndi chromium yochepa komanso nickel. Komabe, imakonda kuchita dzimbiri m’malo achinyezi ndipo imakonda kuchita dzimbiri ikakumana ndi zinthu za acidic, motero imapangitsa kuti zitsulo zolemera ziwonjezeke. Sizingagwirizane ndi zakudya ndi zakumwa kwa nthawi yaitali.

Chitsulo chosapanga dzimbiri cha 304 nthawi zambiri chimatengedwa ngati chakudya chamagulu ndipo chimatha kugwiritsidwa ntchito popanga mzere wa kapu ya thermos; Chitsulo chosapanga dzimbiri cha 316 ndi chitsulo chosapanga dzimbiri chamankhwala, chomwe chimakhala chotetezeka kwambiri komanso chosagwira dzimbiri.

Pofuna kupulumutsa ndalama, amalonda ena osakhulupirika nthawi zambiri amasankha zitsulo zosapanga dzimbiri 201 zotsika mtengo kwambiri monga mkati mwa chikho cha thermos. Ngakhale makapu a thermos oterowo sali osavuta kutulutsa zitsulo zolemera akadzaza madzi otentha, amawonongeka mosavuta akakumana ndi zakumwa za acidic ndi timadziti. Kuwonongeka, kumabweretsa zitsulo zolemera kwambiri.

Zoyenera dziko mfundo amakhulupirira kuti woyenerera thermos chikho akhoza yowiritsa mu 4% asidi asidi njira kwa mphindi 30 ndi ankawaviika kwa maola 24, ndi mkati zitsulo chromium kusamuka kuchuluka si upambana 0,4 mg/mamita lalikulu decimeter. Zitha kuwoneka kuti ngakhale makapu otsika kwambiri a thermos ayenera kukwaniritsa miyezo yotha kusunga zakumwa za carbonated mosamala, m'malo molola ogula kusunga madzi otentha okha.

Komabe, zomangira za makapu osayenerera a thermos pamsika amapangidwa ndi chitsulo chosapanga dzimbiri chotsika kwambiri, chitsulo chosapanga dzimbiri kapena zitsulo zotayidwa, zomwe zingawononge thanzi la anthu.

Chofunika ndikuti mitengo ya makapu a thermos sizinthu zonse zotsika mtengo. Zina zimaposa ma yuan khumi kapena makumi awiri chilichonse, ndipo zina ndi zokwera mpaka yuan imodzi kapena mazana awiri. Nthawi zambiri, 100 yuan ndi yokwanira kuti mabizinesi agwiritse ntchito zida zotetezeka kupanga makapu a thermos. Ngakhale palibe zofunikira zapadera pakutchinjiriza, ma yuan makumi amatha kuchita izi.

Komabe, makapu ambiri a thermos nthawi zonse amagogomezera magwiridwe antchito awo otenthetsera kutentha, kupatsa ogula chinyengo kuti zinthu zawo ndizotetezeka. Posankha chikho cha thermos pamsika, tiyenera kumvetsera ndikuyesera kusankha mtundu wodziwika bwino. Komabe, pali makapu a thermos okhala ndi SUS304 ndi SUS316 pa thanki yamkati.

Pa nthawi yomweyo, muyenera kuona ngati pali zizindikiro za dzimbiri mkati thermos chikho, ngati pamwamba yosalala ndi translucent, ngati pali fungo lachilendo, etc. Nthawi zambiri, thanki wamkati popanda dzimbiri, yosalala pamwamba. ndipo palibe fungo lomwe lingatsimikizire kuti zinthuzo sizichita dzimbiri ndipo zangopangidwa kumene zitsulo zosapanga dzimbiri.

Mitengo ya makapu a thermos omwe ali pamsika amasiyana kwambiri. Makapu otsika mtengo a thermos amagwiritsa ntchito ukadaulo wochotsa mchira ndipo amakhala ndi chipinda chobisika chamchira pansi kuti atetezere kutentha, koma amatenga malo ochulukirapo ndikuchepetsa mphamvu yosungira madzi.

Makapu okwera mtengo a thermos nthawi zambiri amachotsa mapangidwe awa. Nthawi zambiri amagwiritsa ntchito chingwe chopepuka komanso champhamvu chachitsulo chosapanga dzimbiri cha austenitic (cha SUS304 chitsulo chosapanga dzimbiri). Mtundu uwu wa zitsulo zosapanga dzimbiri umayang'anira zomwe zili muzitsulo za chromium pa 16% -26%, zomwe zimatha kupanga filimu yoteteza ya chromium trioxide pamtunda ndipo imakhala ndi kukana kwa dzimbiri.

Komabe, makapu a thermos pamsika omwe amagulitsa ma yuan opitilira 3,000 mpaka 4,000 iliyonse amakhala ndi akasinja amkati opangidwa ndi aloyi ya titaniyamu. Kutsekemera kwa zinthu izi ndi zofanana ndi zitsulo zosapanga dzimbiri. Chinsinsi chake ndi chakuti ndi otetezeka kwambiri, chifukwa titaniyamu sichimayambitsa poizoni wa heavy metal. Komabe, mtengo uwu siwofunika kwenikweni kwa anthu ambiri.

Nthawi zambiri, makapu ambiri a thermos samatengedwa ngati msonkho wa IQ. Izi ndi zofanana ndi kugula mphika kunyumba. Mphika wachitsulo womwe umawononga ndalama zambiri za dola imodzi siwoyipa, koma mwayi wopeza zinthu zotsika kwambiri udzawonjezeka. Chogulitsa chamtengo wapatali kwambiri sichikwaniritsa zosowa za anthu ambiri. Kutengedwa palimodzi, kugula zinthu zamtengo wapatali pa 100-200 yuan ndiko kusankha kwa anthu ambiri.
