Scandium / Cas 7440-20-25 / Malge Powder / SC
Chigadzirwa Zita: Scandium Cas: 7440-20-25 Mf: SC MW: 44.96 Einecs: 231-129-2 Inline Point: 1540 ° C (lit.) Boiling Point: 2836 ° C (lit.) Density: 2.99 g / ml at 25 ° C (lit.) Fomu: poda Ruvara: sirivha-grey
* Scandium ironis inoshandiswa mune yakasarudzika yekuvhara, inochera, ceramices ceramics uye laser indasitiri. * Iyo huru yekushandisa yeScandium nehuremu iri muAluminium-Scandum Alloys yeDiki Aerospace Indasitiki Zvigadzirwa. * Akashanda muSolid State Synthesis yemasango asina kujairika, sc19br28z4, (z = mn, fe, ru kana os). * Aya masango anofarira zvivakwa zvavo uye zvivakwa zvemaginiti. * Izvo zvakare zvinoshandiswawo kuita super alloy. 1 kg / bhegi kana 25 kg / chigubhu kana 50 kg / chigubhu kana zvichienderana nezvinodiwa nevatengi.
Chengetedza mune yakadzvanywa uye inotonhorera yekuchengetedza.
Scandium inofanira kuchengetwa nokungwarira kuti ichengetedze zvivakwa zvaro uye kudzivirira oxidation. Heano mamwe mimwe mirayiridzo yekuchengetedza Scandium:
1. Nzvimbo Scandium munzvimbo inotonhorera, yakaoma uye kuderedza kuratidzwa kune unyoro uye humidity, sekunyorova kunogona kukonzera oxidation.
2. Kana zvichikwanisika, chengetedza iyo mune inert gasi nharaunda (senge argon) kuti uwedzere kuderedza njodzi ye oxidation.
3. Kupisa

5. Label: zvakajeka midziyo yekuchengetedza midziyo yekuona kuti kuzivikanwa kwakakodzera uye kubata.
* Tinogona kugovera dzakasiyana siyana dzekubhadhara nzira dzekusarudza kwevatengi.
* Kana huwandu hushoma, vatengi vanowanzoita kubhadhara kuburikidza Paypal, Western Union, Alibaba, nezvimwe.
* Kana huwandu hukuru, vatengi vanowanzoita kubhadhara kuburikidza t / t, l / c pakuona, Alibaba, etc.
* Kunze kwezvo, vatengi vazhinji uye vanowanda vatengi vanoshandisa alipay kana chathat kubhadhara kuti ubhadhare.
1. Zvichienderana nezvinodiwa zvevatengi vedu, tinogona kupa akasiyana siyana ekufambisa sarudzo.
2. Zvemitambo madiki, tinopa vatambi vekutumira kana masevhisi ekutengesa seFedEx, DHL, tnt, tnt, ems, uye akawanda mamwe manhamba akasiyana ekutakura epasi rese.
3. Tinogona kutakura negungwa kune yakataurwa chiteshi kune yakakura mari.
4. Pamusoro pezvo, tinogona kupa masevhisi akasarudzika zvichibva pane izvo zvinodiwa nevatengi vedu uye hunhu hwezvinhu zvavo.
Paunenge uchitakura Scandium, pane zvidzidzo zvinoverengeka zvakakosha uye kufunga kuti utore kuve nechokwadi chekuchengetedza uye kuyananisa kutevedzera. Heano mamwe mafungiro akakosha kuti arambe achifunga:
1. Reglatory kutevedzera: Tarisa uye tevera mitemo yemuno, yenyika, uye zvepasirese maererano nekufambisa kwemakemikari zvinhu. Scandium haina kuiswa sechinhu chine ngozi, asi chero nhungamiro chaiyo inogona kushanda inofanira kuteverwa.
2. Scandium inofanira kuchengetwa mumidziyo yemitambo yekudzivirira oxidation. Ita shuwa kuti kurongedza kwakanyorwa zvakajeka nezviri zvirimo uye chero zvakaringana kubata.
3. Inerer Gasi: Kana zvichikwanisika, kutakura scandium mune inert gasi (senge argon) kuderedza njodzi ye oxidation panguva yekufambisa.

5. Kubata Precustutions: Ita shuwa kuti vashandi vanobata mutakuri vanodzidziswa nenzira dzakakodzera dzekubata uye vanoziva chero njodzi dzinogona kunge dzine njodzi dzakabatana nezvinhu.
6
7. Maitiro Ekurumidzira: Kukudziridza maitiro ekukurumidzira kana uchiburitswa netsaona kana kufumurwa panguva yekufambisa. Izvi zvinosanganisira kuve neakakodzera nzvimbo yekupaza uye yekutanga rubatsiro matanho akagadzirira nguva dzese.
Scandium inowanzoonekwa seyakaderera-ine chepfu simbi uye haina kuiswa sechinhu chine ngozi pasi pemitemo yakawanda. Heano mamwe makuru mapoinzi nezvechengeteko uye zvingangogona njodzi dze scandium:
1. Chekunze: Iyo Biological mhedzisiro yeScanduum pane vanhu haizivikanwe uye kuve neyakadenga kwayo haina kunyatso funda. Nekudaro, scandium haina kutariswa kuve ine chepfu zvakanyanya kana kukuvadza mune zvidiki zvidiki.
2.. Kuchengetedza kwakakodzera uye kubata kunogona kudzikisira chero njodzi dzakabatana ne oxidation.
3 Zvikuru zviyero zvekuchengetedza zvinofanirwa kutorwa, sekushandisa zvishandiso zvekudzivirira pachako (PPE) uye kushanda munzvimbo dzakanyanyisa, kuti uderedze kuratidzwa.
