Ukukhetha ubucwebe, okokuqala sibheka ukwakheka, khona-ke - kwithegi yentengo. Futhi kungaba kuhle ukubheka ukwakheka: Kuya ngokuthi, insimbi esokeni iyoziphatha kanjani. Abanye babo basheshe baba mnyama noma bebathuntu, abanye - bahlala bengashintshiwe eminyakeni eminingi kamuva.
Ungagqoka imihlobiso kunoma yiziphi izinsimbi ezingadali ukuba ungadli kuwe - futhi eyigugu, futhi cha. Kepha izinsimbi zithambekele emnyama noma ukucaphuna kuzodingeka zihlanzwe kaningi.
Kungani i-metal darmest
Kubucwebecwebe, kusetshenziswa izinsimbi eziyigugu nezingavikeleki, kanye nama-alloys abo. Ukuthambekela kokumnyama noma ukufiphaza kunqunywa yizakhiwo zamakhemikhali zezinto ezibonakalayo - ukuthi iphendula kanjani ukuxhumana nomoya, amanzi, isikhumba. Izinhlobo ezimbili ezinzima zokuphendula:
- Umjuluko. Ngesikhathi samasokisi, insimbi ihlangana nomoya nomswakama, kanye nezinto zamakhemikhali eziqukethwe kuzo. Ukusabela kwamakhemikhali kwenzeka - futhi ungqimba oluthambile oluthambile lokugqwala luyavela ebusweni bayo. Ngakho-ke imihlobiso ibopha noma inciphise.
- Patina. Kwenzeka ekuhlobiseni kusuka ethuneni nasezinkolweni zayo. Kuthuthukiswe isikhathi eside, inomthunzi oluhlaza okotshani, olumpunga noma onsundu. Kwesinye isikhathi isetshenziswa ngqo ukunikeza ukubukeka komkhiqizo wevintage.
Isibonelo, igolide elihlanzekile ngeke liphele futhi alishintshi umbala. Kepha izinsimbi zifakwe ku-alloy yegolide (isiliva, ithusi, i-nickel) zingama-onidized. Ngalesi sizathu, imihlobiso evela egolide elinomugqa ophansi lizogcina ligcwalise.
Izinsimbi ezimnyama ezimnyama
Izinsimbi zivame ukubika:
- ithusi;
- zethusi;
- ithusi;
- isiliva.
I-Copper - insimbi orenji-obomvu. Ngaphansi kwethonya lomoya nomswakama kungoxidiwe, kuthola i-tint ebomvu kanye ne-patina eluhlaza okwesibhakabhaka. I-Copper ingenye yezimbangela eziphambili zokujuluka kwama-alloys wobucwebe.
I-Brass - ICopper Alloy ne-zinc. Imvamisa isetshenziselwa ukudala ubucwebe, inombala wegolide okhanyayo. Ngokushesha ukulahla phansi kwethonya lomswakama nomoya, ngokuhamba kwesikhathi kumbozwe nge-flare eluhlaza okotshani.
I-Bronze - i-alloy eqinile eqinile ne-tin. Njengamanye ama-alloys ethuni, amanzi okulahla ngokushesha, aphendule umswakama nomoya. Ngaphezulu kwethusi kukhona i-flare eluhlaza okotshani, engapenda isikhumba.
Isiliva elihlanzekile livame ukungaphenduli emkhathini. Kepha kuphendula ngama-molecule esibabule aqukethe emoyeni, kwakha isiliva sulfide: nguye onikeza ukuqhuma okumnyama okumnyama okwenziwe ubucwebe besiliva. Kubucwebecwebe, amasampula esiliva 925 asetshenziswa kaningi, aqukethe ithusi, i-zinc kanye ne-nickel - izinsimbi zingaphansi kwe-oxidation. Bazokwenza umhlobiso ngokushesha.
Izinsimbi ezingamnyama zimnyama
Imihlobiso izokonga umbala wabo isikhathi eside uma kunjalo:
- gilding;
- isiliva elihlanzekile;
- insimbi engagqwali.
Ubucwebe nge-giilding bumnyama ngesivinini esihlukile - kuya ngokuthi i-metal isetshenziswa kanjani njengesisekelo. Uma umhlobiso wenziwa ngethusi, ithusi, ithusi noma i-nickel, bese ulahlekelwa ngokushesha okukhulu.
Amasampula esiliva 999 aqukethe ama-99.9% wensimbi enhle. Lapho kudala imihlobiso, akuvamile ukusetshenziswa, kepha uma kusetshenziswe, cishe akumnyama.
Insimbi engenasici ayigqwamu ngempela: i-alloy imelana nokugqwala kanye ne-oxidation. Futhi nokho, ngokuhamba kwesikhathi, angashintsha umthunzi wokuqala uma egqoke imihlobiso kaningi futhi engabanakekeli.
Izinsimbi ezingenzi mnyama
Imihlobiso evela kulezi zinsimbi ihlale ingashintshiwe:
- igolide;
- IPlatinamu;
- niobium;
- titanium;
- UTungstern (Carbide);
- I-Palladium.
Igolide kungenye yezinsimbi ze-inert kakhulu. Imihlobiso eyenziwe ngegolide elihlanzekile ngeke iphele, kepha cishe ayihlangabezani nayo: ngenxa yokuthamba, izingxenye zezabelo zengezwa ensimbi. I-Frequency Gold Alloys Shade ayishintshi.
IPlatinamu - ayimnyama, yize ngokuhamba kwesikhathi ingashintsha kancane umthunzi. Lokhu akubangelwa yi-oxidation, kepha ngama-dents kanye nokuhlaziywa kwensimbi, okuqongelela uthuli. Abanye abaqoqi bayaziswa "yi-patina" enjalo, abayisusi ngokuqondile.
I-Niobium - Menal Menert. Ayiphenduli ngamanzi noma umoya. Ihlala ikhaya kuyo yonke impilo yenkonzo.
I-Titanium iyamelana nokukhuphuka, ukugqwala nokugqwala. Akaphenduli emanzini nomoya kuhlala kukhanya. Kudinga ukunakekelwa okuncane.
UTungsten - Insimbi enzima kunazo zonke esetshenziselwa ukudala ubucwebe. Kubucwebecwebe, i-tungsten Carbide iyasetshenziswa: ayigwiki, ayipheli futhi ayikhemisi amachashazi. Kukhona ne-tungsten yezimboni - ikhwalithi ephansi, eshibhile, ithambekele ekugqwalweni.
I-Palladium - i-Metal, ngombala okufana negolide elimhlophe. Isikhathi eside sihlala siqhakaze, asishintshi umbala.
Izindlela Zokuvimbela
Uma uthanda ubucwebe nemihlobiso kusuka ezinsimbi eziyigugu, kungenzeka ukuthi uyazi ukuthi badinga ukunakekelwa njalo. Ngaphansi kwezimo ezijwayelekile, zihamba kancane kancane. Gwema:
- amanzi anosawoti;
- isikhubekile
- isibabule.
Izici zezemvelo, njengokungcola kanye nomswakama, nazo zidlala indima ebalulekile. Kungcono ukugcina imihlobiso ngaphakathi kwezinga lomswakama ophansi - ngokwesibonelo, egumbini lokulala, hhayi endlini yokugezela.
Njalo dweba imihlobiso ngendwangu ethambile, ikakhulukazi uma iqukethe isiliva noma ithusi: Kuzobasiza ukuthi bahlale isikhathi eside ngesimo. Ngaphezu kwalokho, lesi ngesinye isizathu sokuthola imihlobiso ebhokisini futhi nibancome.
