Txo cov suab nrov, kev tsim kho qhov tob yuav pab nqus cov suab nrov, thiab lub peev xwm txo suab nrov tuaj yeem ncav cuag ntau dua 30%.
Reflective iav hlaws cov ntaub ntawv
Qhov Loj: 90-1180um (Raws li qhov xav tau)
Roundness:> 80% (raws li kev xav tau)
⢠Refractive Index: > 1.5
â £Proportion: approx. 2.5
1 Tus nqi melting tsuas yog 2/3 ntawm cov txhuas
2 Tuag casting efficiency yog 25% siab dua txhuas, hlau pwm casting yog 300-500K siab tshaj txhuas, thiab poob ua npuas ncauj casting yog 200% siab tshaj txhuas
3 Qhov zoo thiab cov tsos ntawm magnesium castings yog pom tseeb zoo dua li txhuas (vim lub thermal load ntawm pwm yog txo, qhov kev soj ntsuam zaus yuav txo tau)
Tam sim no, muaj ob txoj kev npaj tseem ceeb rau kev lag luam hlau calcium hauv tsev thiab txawv teb chaws: electrolysis thiab thermal txo. Lub hom phiaj yog nyob rau hauv cov txheej txheem, cov cuab yeej siv thiab kev nce qib ntawm lub tshuab nqus tsev distillation rau kev npaj high-purity metallic calcium. Electrolysis thiab thermal txo yog cov tshuaj purification txoj kev uas nyuaj rau Npaj siab purity hlau calcium. Siv cov khoom siv calcium ua raw khoom, lub tshuab nqus tsev distillation tuaj yeem siv los npaj cov purity hlau calcium uas muaj purity ntau dua 99.999% (5N).
Nyob rau hauv peb lub teb chaws, calcium tau tshwm sim nyob rau hauv daim ntawv ntawm hlau, uas hnub rov qab mus rau ib tug ntawm cov tseem ceeb tej yaam num pab los ntawm lub Soviet Union rau peb lub teb chaws ua ntej 1958, ib tug tub rog industrial enterprise nyob rau hauv Baotou. Nrog rau txoj kev ua kua cathode (electrolysis) hlau calcium ntau lawm kab. Xyoo 1961, qhov kev sim me me tau tsim cov hlau calcium uas tsim nyog.
Kev lag luam roj teeb txhuas-acid hauv kuv lub tebchaws muaj keeb kwm ntau tshaj li ib puas xyoo. Vim yog cov yam ntxwv ntawm cov khoom pheej yig, thev naus laus zis yooj yim, thev naus laus zis paub tab, tsis muaj kev tso tawm tus kheej, thiab kev saib xyuas tsis pub dawb, nws tseem yuav ua tus thawj coj hauv kev lag luam hauv ob peb xyoos tom ntej no.
