Mayelana nethusi

Ithusiingenye yezinsimbi zokuqala ezatholwa futhi zasetshenziswa ngabantu, ezibomvu ngokunsomi, amandla adonsela phansi athile angu-8.89, iphuzu lokuncibilika elingu-1083.4℃. Ithusi kanye nama-alloy alo asetshenziswa kabanzi ngenxa yokuqhuba kahle kukagesi kanye nokuqhuba ukushisa, ukumelana nokugqwala okunamandla, ukucubungula okulula, amandla amahle okudonswa kanye namandla okukhathala, okwesibili kuphela kwensimbi ne-aluminium ekusetshenzisweni kwezinto zensimbi, futhi sezibe yizinto eziyisisekelo ezibalulekile kanye nezinto zamasu emnothweni wezwe kanye nokuphila kwabantu, amaphrojekthi okuvikela kazwelonke ngisho nasemasimini obuchwepheshe obuphezulu. Isetshenziswa kabanzi embonini kagesi, embonini yemishini, embonini yamakhemikhali, embonini yezokuvikela kazwelonke kanye neminye iminyango. Impuphu ecolekile yethusi iwukugxilisa okwenziwe nge-ore eluhlaza esezingeni eliphansi ephethe ithusi efinyelele inkomba ethile yekhwalithi ngenqubo yokuzuza futhi inganikezwa ngqo kubancibilikisi ukuze bancibilikise ithusi.

Ithusi liyinsimbi esindayo, iphuzu layo lokuncibilika lingu-1083 degrees Celsius, iphuzu lokubila lingu-2310 degrees, ithusi elimsulwa libomvu ngokunsomi. Insimbi yethusi inomoya omuhle kagesi nokushisa, kanti ugesi wayo usezingeni lesibili kuzo zonke izinsimbi, usezingeni lesibili emva kwesiliva. Umoya wayo wokushisa usezingeni lesithathu, usezingeni lesibili emva kwesiliva negolide. Ithusi elimsulwa liyaguquguquka kakhulu, lilingana neconsi lamanzi, lingadonswa libe yintambo engamamitha angu-2,000 ubude, noma ligoqwe libe yi-foil ecishe ibonakale ebanzi kunobuso bombhede.

 

"I-white phosphor copper plating" kufanele isho "i-phosphorus copper ene-white coating phezu kwayo". "I-white plating" kanye ne-phosphorus copper kufanele ziqondwe ngokwehlukana.

I-White plating -- Umbala wokubukeka kwengubo umhlophe. Izinto zokubopha zihlukile noma ifilimu yokudlulisa ihlukile, umbala wokubukeka kwengubo nawo uhlukile. Ukufakwa kwe-phosphorus copper tinning kwemishini kagesi kumhlophe ngaphandle kokudlulisa i-passivation.

 

Ithusi le-phosphorus - ithusi eliqukethe i-phosphorus. Ithusi le-phosphorus kulula ukulihlanganisa futhi linokuguquguquka okuhle, futhi livame ukusetshenziswa ezintweni zikagesi.

 

Ithusi elibomvuiyithusi. Igama layo livela kumbala wayo onsomi. Bheka ithusi ukuthola izici ezahlukahlukene.

Ithusi elibomvu liyithusi elihlanzekile lezimboni, izinga lalo lokuncibilika lingu-1083 °C, akukho ukuguquka kwe-isomerism, futhi ubuningi balo obuhlobene bungu-8.9, okuphindwe kahlanu kune-magnesium. Cishe liyi-15% elinzima kunensimbi evamile. Libomvu ngokubomvu, onsomi ngemva kokwakheka kwefilimu ye-oxide ebusweni, ngakho-ke ngokuvamile libizwa ngokuthi ithusi. Liyithusi eliqukethe inani elithile lomoya-mpilo, ngakho-ke libizwa nangokuthi ithusi eliqukethe umoya-mpilo.

Ithusi elibomvu liqanjwe ngombala walo obomvu onsomi. Akuyona ngempela ithusi elimsulwa, futhi ngezinye izikhathi inani elincane lezinto zokususa i-oxidation noma ezinye izinto zengezwa ukuthuthukisa izinto kanye nokusebenza, ngakho-ke liphinde lihlukaniswe njenge-alloy yethusi. Izinto zokucubungula ithusi zaseShayina zingahlukaniswa ngezigaba ezine ngokuya ngokwakheka: ithusi elivamile (T1, T2, T3, T4), ithusi elingenawo umoya-mpilo (TU1, TU2 kanye nethusi elihlanzekile kakhulu, elingenawo umoya-mpilo), ithusi elisusiwe i-oxidized (TUP, TUMn), kanye nethusi elikhethekile (ithusi le-arsenic, ithusi le-tellurium, ithusi lesiliva) elinenani elincane lezinto zokuhlanganisa. Ukuqhuba kukagesi nokushisa kwethusi kungokwesibili kuphela kwesiliva, futhi kusetshenziswa kabanzi ekukhiqizweni kwemishini yokuhambisa nokushisa. Ithusi emkhathini, amanzi olwandle kanye namanye ama-asidi angewona i-oxidation (i-hydrochloric acid, i-dilute sulfuric acid), i-alkali, isixazululo sikasawoti kanye nezinhlobonhlobo zama-asidi e-organic (i-acetic acid, i-citric acid), inokumelana okuhle kokugqwala, esetshenziswa embonini yamakhemikhali. Ngaphezu kwalokho, ithusi linokushibilika okuhle futhi lingenziwa libe imikhiqizo ehlukahlukene eqediwe kancane kanye nemikhiqizo eqediwe ngokucubungula okubandayo kanye ne-thermoplastic. Ngawo-1970, ukukhiqizwa kwethusi elibomvu kwadlula ukukhiqizwa okuphelele kwazo zonke ezinye izinsimbi zethusi.
