Intambo Ehlanzekile Yesiliva Ecwebezelayo/Ene-Varnished Yesicelo Sekhoyili Yemoto

1. Isingeniso sezinto ezibonakalayo

Isilivakuyinto yamakhemikhali enophawuAgkanye nenombolo ye-athomu 47. Insimbi yokuguquguquka ethambile, emhlophe, ekhazimulayo, ibonisa ukuqhutshwa kukagesi okuphezulu kakhulu, ukuqhutshwa kokushisa, kanye nokubonakaliswa kwanoma iyiphi insimbi. Insimbi itholakala oqweqweni loMhlaba ngesimo sezinto ezimsulwa nezikhululekile ("isiliva sendabuko"), njengengxube enegolide nezinye izinsimbi, kanye namaminerali afana ne-argentite kanye ne-chlorargyrite. Isiliva esiningi sikhiqizwa njengomkhiqizo ohambisanayo wethusi, igolide, i-lead, kanye nokuhluzwa kwe-zinc.

Sekuyisikhathi eside isiliva libhekwa njengensimbi eyigugu. Insimbi yesiliva isetshenziswa ezinhlamvu zemali eziningi ze-bullion, ngezinye izikhathi kanye negolide: nakuba iningi kakhulu kunegolide, lincane kakhulu kunensimbi yemvelo. Ubumsulwa bayo buvame ukulinganiswa ngesisekelo se-mill ngayinye; i-alloy emsulwa engu-94% ichazwa ngokuthi “i-0.940 fine”. Njengenye yezinsimbi eziyisikhombisa zasendulo, isiliva libe nendima ehlala njalo emasikweni amaningi abantu.

Ngaphandle kwemali nanjengendlela yokutshala imali (izinhlamvu zemali kanye ne-bullion), isiliva lisetshenziswa kumaphaneli elanga, ekuhlungeni amanzi, ubucwebe, imihlobiso, izitsha zokudlala ezinenani eliphezulu kanye nezitsha (yingakho igama elithi i-silverware), koxhumana nabo kagesi kanye nabaqhubi, ezibukweni ezikhethekile, ekumbozweni kwamafasitela, ekuhlanganiseni ukusabela kwamakhemikhali, njengombala engilazini enemibala kanye nasezitolo ezikhethekile ze-confectionery. Amakhemikhali alo asetshenziswa efilimini yezithombe kanye neye-X-ray. Izixazululo ze-nitrate yesiliva kanye nezinye izakhi zesiliva zisetshenziswa njengezibulala-magciwane kanye nama-microbiocides (umphumela we-oligodynamic), ezifakwe kumabhandeji kanye nokubopha amanxeba, ama-catheter, kanye nezinye izinto zokwelapha.

2. Incazelo Yokuvimbela Ukushisa

Intambo kamazibuthe efakwe i-polyimide iyakwazi ukusebenza kufika ku-250 °C. Ukufakwa kwentambo kamazibuthe eyisikwele noma engunxande kuvame ukwandiswa ngokuyisonga nge-polyimide noma i-fiberglass tape enokushisa okuphezulu, futhi ama-winding aqediwe avame ukufakwa nge-vacuum cleaner nge-varnish efakwa i-insulating ukuze kuthuthukiswe amandla okufakwa kwe-insulating kanye nokuthembeka kwesikhathi eside kwe-winding.

Amakhoyili azisekelayo aboshwe ngocingo olumbozwe okungenani ngezingqimba ezimbili, ingxenye engaphandle iyi-thermoplastic ebopha amajika ndawonye lapho eshiswa.

Ezinye izinhlobo zokuvikela ukushisa njengentambo ye-fiberglass ene-varnish, iphepha le-aramid, i-kraft papaer, i-mica, kanyei-polyesterIfilimu nayo isetshenziswa kabanzi emhlabeni wonke ngezinhlelo zokusebenza ezahlukahlukene njenge-transformers kanye nama-reactor. Emkhakheni womsindo, ucingo lwesiliva olwakhiwe ngalo, kanye nezinye izinto zokuvikela umswakama ezahlukahlukene, njengokotini (ngezinye izikhathi ezigcwele uhlobo oluthile lwe-coagulating agent/thickener, njenge-beewax) kanye ne-polytetrafluoroethylene (PTFE) kungatholakala. Izinto zokuvikela ezindala zazihlanganisa ukotini, iphepha, noma usilika, kodwa lezi ziwusizo kuphela ekusetshenzisweni kwezinga lokushisa eliphansi (kufika ku-105°C).

Ukuze kube lula ukukhiqiza, ucingo oluthile olusebenzisa amandla kagesi olusezingeni eliphansi lune-insulation engasuswa ngokushisa kwe-soldering. Lokhu kusho ukuthi ukuxhumeka kukagesi emaphethelweni kungenziwa ngaphandle kokususa i-insulation kuqala.
