Ndedzipi nzira dzekuziva mhangura yakachena

1. Tarisa kuoma: iyo yakakwirira kunaka kwemhangurazvishongo, kupfava kwechimiro uye kuchena uye kutsetseka kwepamusoro.Vagadziri vemhangura yemhangura vanotora zvishongo zvemhangura zvemagiramu makumi matanhatu semuenzaniso.Kana vakadhonzwa nemaoko, hapana elasticity, uye kunaka kwavo kunenge 95%.Kana pane zvishoma elasticity, iyo fineness inenge 80% -90%;kana elasticity yakakura, iyo fineness iri pasi pe70%.
2. Tarisa mashanga: cheka kana kupeta zvishongo zvemhangura kuti uone ruvara rwemashanga.Kana zvishongo zvinyoro, mashanga akakora uye akapfava, akatsvuka zvishoma, uye ruvara runenge 95%;kana zvakaoma kukotama nemaoko, mashanga machena uye grey, kana zvishoma zvitsvuku, uye ruvara runenge 90%;kana iyo yakaoma inenge 90% Yakakura, mashanga akajeka matsvuku, yellow-white kana grey, uye fineness inenge 80%;kana mashanga akaoma, tsvina yakatsvuka, yero, khaki uye mamwe mavara, uye fineness inenge 70%;kana lipstick yakasviba, Kana yero ine dema, uye kunaka kuri pazasi 60%.
3. Kupeta nzira: pinza uye kupeta neminwe, yepamusoro-soro yakapfava uye inoshanduka, iri nyore kukotama uye haisi nyore kuputsika;kukotama kwemhando yakaderera kwakaoma, kana kutadza kukotama, uye kumwe kutadza kana kukotama neminwe;copper-clad Iyo yenhema ichatsemuka mushure mekukotama kana kugogodzwa nenyundo nguva shoma;iyo yemanyepo haizokwanisa kumira nekukotama uye iri nyore kutyora.Pane mabhenefiti ehutano anobva mukupfeka zvishongo zvemagineti, izvo zvinowanzove zvine kukosha kwekunaka.
4. Nzira yekukanda: zvishongo zvemhangura zvepamusoro, zvakakandwa pabhodhi, hazvigoni kusvetuka kumusoro, kune "pop" inzwi;Zvishongo zvemhangura zvemanyepo kana zvakaderera zvakareruka, zvinokandwa pabhodhi uye zvinobhoekana zvakanyanya, zvichiita ruzha Zvine crisp.Mazano akanakisisa ekushanda nezvishongo zvemhangura anosanganisira kuedza nemaitiro akasiyana uye kufunga pamusoro pekupedzisa.Mhangura isina kugadzirwa ine sheen inochinja ruvara nekufamba kwenguva.Mabhuroko maviri emhangura pamwe chete neshinda anogona kushandiswa kugadzira mhete dzinonakidza, nekiresi, zvishongo nemhete.
Mhangura yakachena, sezvinoreva zita, imhangura ine yakanyanya kunaka mhangura, nekuti ruvara rwepepuru-tsvuku, inozivikanwawo semhangura tsvuku.Chinhu chikuru imhangura nesirivha, uye zviri mukati 99.5-99.95%.Main kusachena zvinhu: phosphorus, bismuth, antimony, arsenic, simbi, nickel, lead, tini, sarufa, zingi, okisijeni, etc. Pakugadzira conductive midziyo, advanced copper alloys, mhangura-based alloys.
