Isiliva lobuchwepheshe: Kuyini nokuthi yiliphi iphuzu lokuncibilika, lapho liqukethe, isampula nokwakhiwa kwalo

Isiliva - kude nesici esijwayele kakhulu lapho ubucwebe nezesekeli ezikhiqizwa ngalo, kodwa izinto ezibalulekile lapho kudala amadivayisi ahlukahlukene. Le nsimbi, esetshenziswa embonini yezimboni yokwenziwa kwamadivayisi nezakhi zobuchwepheshe, isiko lokubizwa ngokuthi "ezobuchwepheshe".

Ubuhlakani

Isiliva lobuchwepheshe yinto equkethe cishe ama-altoy angamashumi amabili. Inezici eziningi ezihlukanisa kwezinye izinto:

• Ukuvuselelwa okuphezulu okuphezulu nokusebenza kukagesi;
• IMonolithium kanye nokumelana nokubhujiswa;
• ukuqina nokuthamba okuhlobene;
• amandla okubonisa ukukhanya;
• zifanekiswe ekuphenduleni kabusha;
• Iphuzu eliphansi elincibilikayo.

Imininingwane enjalo iyabonakala Funa isiliva lobuchwepheshe ezimbonini ezahlukene . Izakhiwo zayo ezinjalo zamakhemikhali e-physico-, njengesikhathi eside sokusebenzisa nokulwa nokuwohloka, kwakha izinhlobo eziningi zezicelo.

Isetshenziswa kaningi ezindaweni ezinjalo: umuthi, izindiza, ubunjiniyela kanye nobunjiniyela bogesi.

Ku-pawnshop, intengo yegremu eyodwa yensimbi enjalo izoba ngama-ruble angamashumi amathathu.

Ukwakheka

Isici esibalulekile sesiliva sobuchwepheshe Ukuhlanzeka Okuphezulu Okuphezulu - 99.9% . Kulokhu, inani lazo zonke izinhlobo zokungcola lilingana no-0.1%. Kepha kufanele kuqashelwe ukuthi, ngokungafani nesiliva lobucwebe, Umsebenzi oyinhloko walesi sinsimbi awusiwo ama-aesthetics, kepha ukubaluleka kokwenziwa kobunjiniyela beRadio.

Kungukuhlanzeka kwensimbi - isisekelo sokusebenza okuhle okushisayo nogesi, kwenza le nto inenjongo embonini.

Uma sibheka le amaphesenti amancane okungcola, siyaphawula Izakhi eziphambili: I-Nickel, ithusi, igolide, njll. Kaningi ku-metal emsulwa esetshenzisiwe Isampula le-999 Kepha emcimbini wokuthi iqukethe ngaphezu kwe-10% yethusi, isampula izoba ngu-800. Futhi ngokuqukethwe okuphezulu, insimbi ingathenga i-tint ephuzi, kepha iba namandla kakhulu.

Isampula 830. Ihlangabezana neqiniso lokuthi ukungcola kungama-gramu ayi-170, namagremu asele angama-830 - esiliva uqobo. I-Metal enjalo isetshenziselwa izinhloso zokuhlobisa (lapho kudala imihlobiso ehlukene noma izesekeli). Le nto ekwenziweni kwezitsha zasendlini igcwele (izingilazi zesiliva, izinkomishi, nezinkezo, imfoloko, njll.).

Kubonakala ngamandla aphezulu kanye nokumelana nazo zonke izinhlobo zomonakalo womzimba.

Isiliva S. Iloli 875. Kuyi-alloy emhlophe futhi namanje akulungele ukwenza ubucwebe. Iningi elisetshenziswa kakhulu ezindlini zamasongo kanye nama-wristwatches. Kulesi sinsimbi, inani lezithasiselo lilinganise ukuvezwa kwalo kunoma yimuphi umonakalo womzimba.

Njengoba wazi, kuyisiliva Imikhiqizo 925 Test Ilungele ukudala ubucwebe. Insimbi ifaka isiliva nethusi ngezilinganiso ezinjalo: 92.5% no-7.5%, ngokulandelana.

Umgodi onomthombo wamanzi Ukwakheka kwesiliva lobuchwepheshe kubonakaliswa ukuhlanzeka okukhulu kwensimbi nangokungatholakali kokungcola . Yile mininingwane evumelana nezimo futhi ithambile, ngakho-ke ibaluleke kakhulu ekwakheni amadivayisi wobunjiniyela bomsakazo.

Ungahlukanisa kanjani ubucwebe?

1. leli I-Metal "Transparent", ngaphandle kwezithasiselo eziningi Lokhu, ngokungafani nobucwebecwebe ubucwebe, kuyakwazi ukushisa okuhle nokushisa kukagesi, ukukhombisa okukhanyayo, okuvumela izinto ukuthi zikhiqize izingxenye zazo zonke izinhlobo zemishini.
2. Isikhombisi esibalulekile - Isampula. Lapho wenza imihlobiso ehlukahlukene noma izesekeli, ukuhlolwa okuphezulu akufanelekile, ngoba umsebenzi oyinhloko walesi sakhi ukudala imikhiqizo ehlala isikhathi eside, ethembekile ezokuhlala isikhathi eside. Futhi inketho yezobuchwepheshe, njengoba kuphawuliwe ngenhla, ithambile kakhulu futhi ivumelana nezimo.
3. Njengoba sesivele sazi Isiliva yezimboni iqukethe izithasiselo ezingama-0,1% kuphela Futhi-ke, ukubheka ukuthi kuzokwenza yini, kuzothatha ulwazi ngamaphuzu athile asemqoka. Ungathela uviniga kunoma yimiphi imininingwane - inqubo ye-oxidation kufanele yenzeke. Noma uzokusiza ukwehla kwe-iodine, emva kwalokho insimbi izomnyama. Lokhu kusho ukuthi umkhiqizo uqukethe amaphesenti aphezulu esiliva elihlanzekile.
4. Futhi ekugcineni, naphezu kweqiniso lokuthi inani lokungcola liphansi, okwamanje Ezinye izinto zihlukaniswa yilensimbi ebucwebecwebe. . Isibonelo, ukuba khona kwe-nickel kungadala ukusabela komzimba nokulunywa. Namacici ngokuqukethwe kwale nto kungaholela emiphumeleni emibi kakhulu.

Ukuba khona kokuhola kusongela ukubukeka kwezinhlungu zekhanda, ukukhubazeka, njll. Ngokwesiliva elinjalo, ukwakheka kwakhiwa ithusi ne-aluminium, benza ukuvumelana ngensimbi futhi kuthambile, akufanelekeli ukukhiqizwa kobucwebecwebe.

Ngakho-ke, kunezikhathi eziningi ezibalulekile ezizokusiza ukuhlukanisa isiliva lobuchwepheshe ezintweni ezisebenza njengesisekelo sazo zonke izinhlobo zokuhlobisa nezinye izinsimbi.

Kuqukethwe kuphi?

Siligcina kuphi isiliva lobuchwepheshe? Kukumadivayisi wanamuhla, kepha Emavoluni amakhulu - kuphela emishini yaseSoviet. Zonke izinsimbi eziyigugu ezazigcinwe emininingwaneni zazisesimweni sayo esimsulwa. I-accounting eqinile yaqhutshwa ngemuva kwayo, njengoba yakha inani elikhulu kakhulu.

Insimbi eyigugu isemabhokisini anjalo aziwa ngathi nemininingwane:

• Ama-Photopiles nezithombe zama-X-ray;
• Izintambo embonini yezindiza kanye nobunjiniyela bemishini;
• ama-chips, ama-chips, oxhumana nabo, ama-plugs, izisekelo;
• Izindlu zemishini yomsakazo nezogesi, imininingwane yazo;
• Amabhethri, ukushintshwa, ukushintshana.

Kusetshenziswa kuphi?

Isiliva lobuchwepheshe liyingqayizivele linezici eziningi ze-physicochemical ezikwenza zilungele ukusetshenziswa ekwenziweni Imishini yomsakazo. Njengoba kushiwo ngenhla, izinga lokungcola ngensimbi licishe lilingane no-zero, nokho, i-nickel, ithusi, ukuhola nokunye okungeziwe ukuze kuthuthukiswe ukulahlwa kwalo. Ukusabalalisa okubanzi kule nto etholwe ekwenziweni kwamasosha.

I-tandem edume kakhulu ye-Copper / yesiliva isetshenziselwa ukudala zonke izinhlobo zemishini yomsakazo, imishini yobuchwepheshe be-elekthronikhi, kanye nangoxhumana nabo abahlelekile kagesi.

Uma kwenzeka ukuthi inani lesiliva libusa, khona-ke Ukuxhuma okuhlala isikhathi eside nokulwa nokugqwala . Ngokuqukethwe kwethusi okuphezulu kungahle kube ngaphansi kokukhubazeka nokubhujiswa. I-Palladium Alloy enensimbi yezobuchwepheshe idlula isibonelo esingenhla. Ngenxa yokuba khona kwesibabule ekuxhumaneni kwabo Kubonakala ngokumelana nokugqwala nokuncipha okuncane kokuqola.

Ungafika kanjani ekhaya?

Ufuna izandla zakho ukuhlanza isiliva kusuka ekungcoleni ukuze uthole insimbi ehlanzekile, kepha ungazi ukuthi ukukwenza kanjani kahle? Sizokunikeza i-algorithm yezenzo okudingeka unamathele kuzo.

Kungcono ukuthi unqume kusengaphambili ukuthi yimuphi ukungcola okuqukethwe ekwakhiweni kwensimbi (igolide, i-nickel, ePalladium, ithusi, ukuhola).

Kusukela ekhaya awekho imishini yelabhoratri enjalo, kepha kunezinye izindlela zokuqokomisa lezi zithangezo.

1. -Funeka Spread yensimbi kuya izingcezu ezincane kakhulu bese wenza ukwelashwa nge-nitric acid . Qiniseka ukuthi ulandela imithetho yezokuphepha lapho usebenza namakhemikhali, yenza igumbi ukuze lingatholi ubuthi. Hlanganisa i-reagent nensimbi ukunwebeka kuze kube yilapho sekuchitheke ngokuphelele. Uma uthola umthunzi oyimpuphu njengomphumela, uphakamisa ukuthi iqukethe ithusi.
2. Into enjenge-sodium sulfate izokusiza nquma ubukhona ekuholeni kwalo kwezakhi . Ngemuva kokuhlolwa kwenziwa, ukuhola kufanele kuwele ekuweni.
3. I-Copper inganqunywa ngu-ammonia utshwala okuzoyipenda ibe ngombala oluhlaza oliveziwe. Kubalulekile ukuqaphela! Ukucinga izengezo ngaphakathi kwensimbi eyigugu, sebenzisa izingcezu ezintsha ngaso sonke isikhathi ukuze ugweme zonke izinhlobo zamaphutha.
4. Khona- Hlukanisa isiliva kusuka ethubeni . Ukudonswa okuphumayo kumele kube nzima ukuguquguquka komile, bese kufakwa. Ngakho-ke, izinhlayiya zesiliva zizophumelela inqubo yokubola kwensimbi, ngenkathi izinto ezisele ziba yi-oxides.

Lapho usebenzisa i-acetic acid, ukuvumelana okusele kuhlungwa ngokukhethekile futhi ngemuva kokubhoboza ikhambi kusawoti. Ngemiyalo eqondile elandelayo nokusebenza kanzima, uzofinyelela umphumela oyidingayo.

Kuyaziwa ukuthi ihlanzeke kahle insimbi eyigugu eyigugu iyabiza kakhulu kunesikhafu se-classic. Ngakho-ke, umsebenzi wakho uzokwaziswa ngokunembile. Kepha khumbula ukuthi Le nqubo inzima kakhulu ukunikeza okokuqala ngqa, njengoba idinga amakhono namakhono ochwepheshe.

Ekuphetheni, singasho lokho Isiliva lobuchwepheshe - hhayi insimbi ejwayelekile kakhulu. Inezici eziningi ezihlukanisa ubucwebecwebe isiliva. Naphezu kweqiniso lokuthi le nto yasetshenziswa kabanzi ekwakheni amadivayisi weSoviet, igcina ukuthandwa kwayo futhi okwamanje.

Ukubuka konke koxhumana nabo abefundisi ababiza kakhulu kuvezwa kuvidiyo.
