* I-Scandium Metalis esetshenziswe ku-Optical Coating, i-Catalyst, i-ceramics ye-elektroniki kanye ne-laser imboni. * Ukusetshenziswa okuyinhloko kweScandium ngesisindo ku-Aluminium-Scandium Alloys yezakhi ezincane zezimboni ze-AeroSpace. * Oqashwe ku-sloust synthers eqinile yamaqoqo angajwayelekile, i-SC19BR28Z4, (Z = MN, FE, FE noma OS). * Lawa maqoqo athakazelisa ngesakhiwo sawo kanye nezakhiwo zakwamabuthe. * Kusetshenziswa futhi ukwenza i-Super Alloy. 1 kg / isikhwama noma i-25 kg / isigubhu noma ama-50 kg / isigubhu noma ngokuya ngesidingo samakhasimende.
Gcina indawo yokugcina umoya evulekile futhi epholile.
I-Scandium kufanele igcinwe ngokucophelela ukuze ilondoloze izakhiwo zayo futhi ivikele i-oxidation. Nazi ezinye izinkombandlela zokugcina iScandium:
1. Imvelo: Isitolo Scandium endaweni epholile, eyomile futhi unciphise ukuvezwa komswakama nomswakama, njengoba umswakama ungadala i-oxidation.
2. Isitsha: Sebenzisa iziqukathi ezivaliwe ezenziwe ngezinto ezingasebenzi kahle, njengengilazi noma amapulasitiki athile, ukuvikela ukuxhumana nomoya. Uma kungenzeka, gcina endaweni yegesi i-inert (njenge-argon) ukuze uphinde unciphise ubungozi be-oxidation.
3. Ukushisa: Gcina iScandium ekushiseni okuzinzile futhi uvikele ukushisa ngokweqile noma ukubanda, okungathinta izakhiwo zayo ezibonakalayo.
4. Ukuhlukaniswa: Gcina iScanDIUM kude nama-acid aqinile, izisekelo namanye amakhemikhali asebenzayo ukuvikela ukusabela okungafuneki.
I-5. Ilebula: Faka ilebula ngokucacile iziqukathi zokugcina ukuze uqinisekise ukuhlonza okufanele nokuphatha.
* Singahlinzeka ngezindlela ezahlukahlukene zokukhokha zokukhetha amakhasimende.
* Lapho inani lincane, amakhasimende ajwayele ukukhokha nge-PayPal, Union asentshonalanga, i-Alibaba, njll.
* Lapho inani likhulu, amakhasimende ajwayele ukukhokha nge-T / T, l / c lapho ebonakalayo, i-Alibaba, njll.
* Ngaphandle kwalokho, amakhasimende amaningi futhi amaningi azosebenzisa i-Alipay noma i-WeChat akhokhe ukuze akhokhe.
1. Ngokuya ngezidingo zamakhasimende ethu, singanikeza izinketho eziningi zokuhamba.
2. Ngemiyalo emincane, sinikezela ngezinsizakalo zokuthumela zomoya noma zokuhambisa izithumo ezinjenge-FedEx, DHL, TNT, EMS, kanye neminye imigqa eyingqayizivele ye-International Transit.
3. Singakwazi ukuthutha ngolwandle kuya ethekwini elicacisiwe lamanani amakhulu.
4. Ngaphezu kwalokho, singanikeza izinsizakalo ezihlukile ngokuya ngezidingo zamakhasimende ethu kanye nezimpawu zempahla yazo.
Lapho uhambisa iScandium, kunezinyathelo ezimbalwa ezibalulekile zokuqapha kanye nokucatshangelwa okufanele uzithathe ukuze kuqinisekiswe ukuphepha kokuphepha nokulawula. Nayi eminye imininingwane ebalulekile okufanele uyikhumbule:
1. Ukulandela umthetho wokulawula: Bheka imithethonqubo yasekhaya, kazwelonke, neyamazwe omhlaba maqondana nokuhamba kwezinto zamakhemikhali. I-Scandium ayihlukaniswa njengento eyingozi, kepha noma yiziphi izinkombandlela ezithile ezingasebenza kumele zilandelwe.
2 I-Scandium kufanele igcinwe ezitsheni ze-airtight ukuvikela i-oxidation. Qinisekisa ukuthi ukufakwa kubhalwe ngokucacile nokuqukethwe kanye nanoma yimiphi imiyalo efanelekile yokuphatha.
3. I-inert gesi: Uma kungenzeka, i-Scandium yezokuthutha ephepheni le-inert (njenge-argon) ukunciphisa ubungozi be-oxidation ngesikhathi sokuhamba.
I-4. Ukulawulwa kokushisa: gcina izimo zokushisa ezinzile ngesikhathi sokuhamba ukuvikela noma yiziphi izinguquko ezingaba khona ezintweni ezibonakalayo.
5
I-6. Imibhalo: Nikeza yonke imibhalo edingekayo kufaka phakathi ishidi ledatha yezokuphepha (SDS), ukuhambisa okubonakalayo kanye nanoma yimiphi eminye imibhalo edingekayo ukuqinisekisa ukuthunyelwa kanye nokuhambisana nemigomo.
7. Izinqubo eziphuthumayo: ukuthuthukisa izinqubo eziphuthumayo uma kwenzeka kukhululwe ngengozi noma ukuvezwa ngesikhathi sokuhamba. Lokhu kubandakanya nokuba nezindawo ezifanelekile zokuchitheka kanye nezinyathelo zokuqala zosizo lokuqala zilungele ngaso sonke isikhathi.
I-Scandium ngokuvamile ithathwa njengensimbi enobuthi ephansi futhi ayihlukaniswa njengento enobungozi ngaphansi kwemigomo eminingi. Nawa amanye amaphuzu asemqoka mayelana nokuphepha nezingozi ezingaba khona zeScandium:
1. Ubuthi: Imiphumela yemvelo yeScandium kubantu ayaziwa futhi ubuthi bayo bungafundwanga ngokuphelele. Kodwa-ke, iScandium ayithathwa njengento enobuthi kakhulu noma eyingozi ngamanani amancane.
2. Ukusebenza kabusha: Ngenkathi iScandium iyinsimbi esebenzayo ezokwenza i-oxidize lapho ivezwa emoyeni, ayibeki ingozi enkulu esimweni sayo esiqinile. Isitoreji esifanele nokusingathwa kunganciphisa noma yiziphi izingozi ezihambisana ne-oxidation.
3. Uthuli kanye nomucu: Njengasezinkalweni eziningi, uthuli noma intukuthelo noma ama-cunchling noma isikena se-scandium kungahle kucasule uhlelo lokuphefumula. Kufanele kuthathwe izinyathelo zokuphepha ezifanele, njengokusebenzisa imishini yokuzivikela (i-PPE) nokusebenza ezindaweni ezinomoya omncane, ukunciphisa ukubonakaliswa.
