Origin
Munyika yedu, calcium yakaonekwa muchimiro chesimbi, iyo yakadzokera kune imwe yemapurojekiti akakosha akabatsirwa neSoviet Union kunyika yedu pamberi pe1958, bhizinesi remauto reindasitiri muBaotou. Kusanganisira iyo yemvura cathode nzira (electrolysis) simbi karusiyamu yekugadzira mutsara. Muna 1961, muyedzo mudiki-diki wakagadzira inokwanisa simbi calcium.
Development:
Yakarongedzerwa kumagumo e1980s kusvika kumavambo 1990s, nekugadziriswa kwenyika kwemaindasitiri emauto maindasitiri uye chirevo che "chiuto-ku-chivanhu" mutemo, simbi calcium yakatanga kupinda mumusika wevanhu. Muna 2003, sezvo kudiwa kwemusika kwesimbi calcium kwakaramba kuchiwedzera, Baotou Guta rave nyika hombe simbi yekugadzira simbi yesimbi, Iko kune ina mana electrolytic calcium mitsara yekugadzira, ine gore negore kugadzirwa kwe5,000 matani esimbi calcium uye zvigadzirwa.
Kubuda kweCalcium Aluminium Alloy:
Nekuda kwekunyungudika kwakakwirira kwemetallic calcium (851°C), kuparara kwekupisa kwecalcium mukuita kwekuwedzera metallic calcium mumvura yakanyungudutswa yelead yakakwira kusvika 10%, izvo zvinotungamira kumitengo yakakwira, kuoma kwekugadzirisa kuumbwa, uye kureba. simba rinopedza nguva. Naizvozvo, zvinodikanwa kugadzira alloy nesimbi aruminiyamu uye simbi karusiyamu kuti zvishoma nezvishoma kunyunguduka layer by layer. Kuonekwa kwekarusiyamu aruminiyamu alloy yakanyatsonangana nekugadzirisa chikanganiso ichi mugadziriro yekugadzira lead calcium aluminium alloy.

Kugadzirwa kwekarusiyamu aruminiyamu alloy inzira yekunyunguduka uye kusanganisa muvacuum state uchishandisa tembiricha yakakwira zvichienderana nehumwe chiyero chesimbi calcium nesimbi aluminium.
Iyo Classification yeCalcium Aluminium Alloy:
Calcium aruminiyamu alloy inowanzoiswa 70-75% calcium, 25-30% aruminiyamu; 80-85% calcium, 15-20% aluminium; uye 70-75% calcium 25-30%. Inogonawo kugadzirwa Sezvinodiwa. Calcium aruminiyamu alloy ine simbi inopenya, inoyevedza hunhu, uye hupfu hwakatsetseka huri nyore kupisa mumhepo. Inonyanya kushandiswa se master alloy, kunatsa uye kuderedza mumiriri mukunyungudutsa simbi. Zvigadzirwa zvinopihwa muchimiro chezvivharo zvechisikigo, uye zvinogona zvakare kugadziriswa kuita zvigadzirwa zvemhando dzakasiyana siyana zvichienderana nezvinodiwa nemushandisi.
The Quality Classification ye
Se master alloy, zvinodiwa zvemhando yecalcium aluminium alloy zvakanyanya kuomarara. (1) Zviri mukati mesimbi kalsiyamu inochinja-chinja mune diki renji; (2) Iyo alloy haifanirwe kuve nekuparadzanisa; (3) Kusvibiswa kunokuvadza kunofanira kudzorwa mukati mehutano hwakanaka; (4) Panofanira kunge pasina oxidation pamusoro peiyo alloy; Panguva imwecheteyo, kugadzirwa, kurongedza, kutakura uye kuchengetedza calcium aluminium alloy inodiwa Iyo nzira inofanirwa kunyatsogadziriswa. Uye vagadziri vecalcium-aluminum alloys yatinopa vanofanira kunge vane magwaro epamutemo.
Kutakura uye kuchengetedza
Iyo kemikari yecalcium aluminium alloy inoshanda zvakanyanya. Zviri nyore kuita oxidize uye kupisa zviri nyore kana yaiswa pamoto, mvura uye zvakanyanya kukanganisa.
1. Packaging
Mushure mekunge calcium aluminium alloy yapwanyika maererano neimwe tsanangudzo, inoiswa muhombodo yepurasitiki, inoyerwa, izere neargon gasi, yakavharwa-yakavharwa, uye yozoiswa mudhiramu resimbi (international standard drum). Iyo simbi yesimbi ine yakanaka isina mvura, mhepo-yega uye anti-impact mabasa.
2. Kuisa nekuburitsa
Panguva yekurodha uye kurodha, forklift kana crane (magetsi hoist) inofanira kushandiswa kurodha nekuburitsa. Madhiramu esimbi haafanire kukungurutswa kana kukandwa pasi kudzivirira kukuvara kwebhegi rekurongedza uye kurasikirwa kwedziviriro. Mamwe mamiriro akakomba anogona kukonzera kupisa kwecalcium aluminium alloy mudhiramu.
3. Kutakura
Panguva yekufambisa, tarisa pakudzivirira moto, kudzivirira mvura uye kudzivirira kukanganisa.
4. Kuchengeta
Hupenyu hwesherufu yecalcium aruminiyamu alloy mwedzi mitatu pasina kuvhura dhiramu. Calcium aruminiyamu alloy haifanirwe kuchengetwa panzvimbo yakashama, uye inofanira kuchengetwa munzvimbo yakaoma, isinganayi mvura. Mushure mekuvhura bhegi rekurongedza, rinofanira kushandiswa zvakanyanya sezvinobvira. Kana iyo alloy isingagone kushandiswa kumusoro panguva, mhepo iri mubhegi rekurongedza inofanira kupera. Sunga muromo zvakasimba netambo, uye udzorere mudhiramu resimbi. Chisimbiso kudzivirira alloy oxidation.
5. Inorambidzwa zvachose kupwanya calcium-aluminium alloy mumadhiramu esimbi kana mabhegi ekuputira ane calcium-aluminium alloy kudzivirira moto. Kupwanya kwecalcium aruminiyamu alloy kunofanirwa kuitwa pane aluminium ndiro.
