Utsotso pfungwa mutobvu

Kutungamirira - simbi rinokwanisa kucheneruka Hue ane hombe chaizvo giravhiti uye substantially shoma neukukutu (anogona kubviswa nebanga). Utsotso pfungwa mutobvu Zviri zvokuti rinogona muchanyauswa mukati moto kana mumba. kutungamirira Kwakachena iri kukurumidza yakafukidzwa ane oxide firimu uye kukanganisa. At kwomuzvarirwo tembiricha kutungamirira zviri inert kune acids vakawanda.

Utsotso pfungwa vatungamirire, vasina tsvina, anenge madhigirii anenge 328. The yakanyungudutswa chimiro simbi ane castability akanaka. Kana kudira kutungamirira kupinda jecha muforoma zvakakodzera kuti simbi aiva fluidity yakanaka, izvi pakupedzisira uchanyangadika angasvikira imwe tembiricha pamusoro utsotso pfungwa dzinenge 100-120 inegumi. Nyore machine psac, ndokugadzira, mukuru ductility simbi laminate kunoita kuti shoma jira ukobvu nyore.

The Kubika pfungwa mutobvu iri kuwanda 1749 °.

In yakaumbwa nehurumende ine chinokosha volatility, iyo kunowedzera tembiricha. Lead guruva, uye peya vatungamirire oxides vari muchetura kuti muviri womunhu. Kuvapo iri muviri kuti 0.3 g mutobvu kana yenhengo dzayo, zvinotungamirira zvikuru chepfu. Muna crystallization muitiro hombe kutungamirira asingatani shrinkage, kazhinji anenge 3.5%. The Earth nechepasi kutungamirira rinowanzoshandiswa kuwanikwa muchimiro yeimwe, yakachena chimiro, zviri zvisinganyanyi kuitika.

It Vakawana kuti kunyanya kuwanikwa muchimiro sulfides zviri namatombo siyana.

Sezvo nouipi mukati zvingava zvinhu zvakadai namavara akanaka, mhangura, simbi, tini, bismuth, Arsenic, yavaibvisa, etc. Vazhinji netsvina iri chisingadiwi, kunyanya zvaAtemisi dzinonetsa zvikamu, nekuti hunozoita kuti munhu dikidiki makemikari uye zvemaziso zvivako zviri simbi. Zingi uye kutungamirira bismuth kuderedza kuramba acids. Kuvapo magnesium kana karusiyamu kunotungamirira kuwedzera simba, uye simbi yakapambadzirwa pamwe namavara akanaka, dzinoratidzwa vakawanda zvibereko pokuoma.

Copper anowedzera nemishonga yacho vatungamirire chigadzirwa kune sulfuric acid, barium uye lithium kwakawedzera neukukutu. Utsotso pfungwa mutobvu pamberi nouipi hakuiti chaidzo kuchinja. Kuwanda kushandiswa Zvigadzirwa mutobvu rakafara zvakakwana. vatengi Major izvi zvinhu runoonekwa kuti waya uye matochi kugadzirwa, apo rinoshandiswa sezvo waya mumuhara uye anogadzira zvinhu bhatiri kwamahwendefa.

Made mutobvu wapfura uye nemabara. The pasi utsotso pfungwa mutobvu akabvumira kare vavhimi kuti mabara vapfurwa.

Anticorrosive nemano mutobvu kubvumira kushandiswa kwayo kuti kushandisa rwokudzivirira rukoko pamusoro zvinhu zvesimbi. Uyezve, pfuma iri kutungamirira zvinowanzoshandiswa anogadzira zvinhu pendi uye varnishes. A chikuru chezvinonhuwira chikepe minium, izvo ruvara ari pasi pemvura muchikepe, ane ruvara inobva kutungamirira.

Kutungamirira mumuhara anokwanisa kudzivirira pamusoro ngura yemagetsi uye runhare wire akaisa pasi pasi uye mvura mumamiriro ezvinhu outsinye. At chii tembiricha itye vatungamirire, tini, bismuth uye cadmium, anoziva kugadzirwa kwezvinhu dzemagetsi fuses. Kusvikira nhasi kudiwa kutungamirira-asidhi mabhatiri iri motokari, kudzivirira uye mamwe maindasitiri mazhinji. Zvisinei, mumakore achangopfuura, vakatanga kushingaira kushandisa nickel-cadmium mabhatiri.

Kutungamirira chiwanikwa nziyo iri zvinowanzoshandiswa anogadzira zvinhu Babbitt inobereka solder kuti tini nomutobvu alloys rokudhinda. Machira akaita mutobvu-zvaitawo maekisirei uye radioactive nemwaranzi. Tsaona yakaitika muna 1986, panguva paChernobyl, achiperekedzwa zvikuru radioactive nemwaranzi, kuti vadzivire kwacho reactor, uchishandisa masaga mutobvu bara uye vatungamirire blanks.

Kuti adzivirire vanhu pamusoro neherikoputa kwaigara ichi mutoro, kutungamirira paishandiswa mapepa. The yakasiyana ehupfumi mutobvu iyi nyaya zvakazoonekwa kuti chinokosha.
