Cruciblesmaturusi akakosha mumaindasitiri akasiyana ekubata kunyungudika nekunyungudutsa.Igaba rinokwanisa kumira kutonhora kwakanyanya uye rinoshandiswa kubata zvinhu nekuzvipisa kusvika pakunyungudika.Mhando dzakasiyana dzemacrucibles anoshandiswa zvichienderana nezvinodiwa chaizvo zvezvinhu zviri kunyungudutswa kana kunyungudutswa.Mune ino blog post, isu tichaongorora akasiyana marudzi emacrucibles uye mashandisiro awo.
1. Iron crucible:
Shandisa iron crucible paunenge uchinyungudutsa zvinhu zvine alkaline zvine simba seNaOH.Nekudaro, haisati yashandiswa zvakanyanya nekuda kwezvinetso zvakaita sekukora nyore uye oxidation.Mumashandisirwo mazhinji anosanganisira alkaline zvinhu, inert simbi crucibles inoramba iri sarudzo yakasarudzika.
2. Chigadziko chesimbi:
Zvimedu zvesimbi zvakakandwa zvinogadzirwa kubva kusimbi yenguruve uye inozivikanwa nekusimba kwayo.Inoshandiswa kunyungudutsa akasiyana simbi alloys anosanganisira aluminium, zingi, lead, tin uye antimony alloys.Kuenzaniswa nesimbi crucibles, cast iron crucibles inogara yakasimba uye inogona kumira kutonhora kwakanyanya kunodiwa kunyungudutsa aya alloys.
3. Quartz crucible:
Quartz crucibles inowanzo shandiswa muindasitiri yesemiconductor uye yakakosha pakugadzirwa kweakakura-akabatanidzwa maseketi.Aya macrucibles anogona kumira tembiricha inosvika 1650 madhigirii uye anowanikwa mune akajeka uye opaque shanduro.Translucent quartz crucible inogadzirwa nearc nzira, inoshandiswa kudhonza yakakura dhayamita imwe crystal silicon.Iyo ine mabhenefiti ekuchena kwepamusoro, yakasimba tembiricha kuramba, hombe saizi, yakanyanya kurongeka, yakanaka yekupisa kupisa kuita, kuchengetedza simba, uye yakagadzikana mhando.Zvisinei, kutarisirwa kunofanira kutorwa sezvo quartz iri brittle uye inogona kuputsika nyore nyore.
4. Porcelain crucible:
Ceramic crucibles dzakakurumbira nekuda kwemakemikari kuramba uye kugona.Nekudaro, haigone kushandiswa kunyungudutsa alkaline zvinhu zvakaita seNaOH, Na2O2, Na2CO3, nezvimwewo, nekuti ivo vanozosangana ne porcelain uye kukonzera ngura.Mukuwedzera, porcelain crucibles haifaniri kusangana ne hydrofluoric acid.Iwo akakodzera kushandiswa pakudziya kwakapoteredza 1200 degrees.
5. Corundum crucible:
Corundum crucible yakanyatsokodzera kunyungudusa samples uchishandisa zvisina kusimba alkaline zvinhu zvakaita seanhydrous Na 2 CO 3 se flux.Nekudaro, iwo haana kukodzera kunyungudutsa sampuli uchishandisa zvine simba alkaline zvinhu (seNa2O2, NaOH) kana acidic zvinhu (senge K2S2O7) se fluxes.
6. Graphite crucible:
Graphite crucibles anoshandiswa zvakanyanya muindasitiri yekukanda simbi nekuda kweakanakisa ekupisa conductivity uye yakakwirira tembiricha kuramba.Dzakakodzera kunyungudutsa simbi dzakasiyana-siyana dzinosanganisira mhangura, goridhe, sirivha nendarira.
7. Silicon carbide crucible:
Silicon carbide crucibles inozivikanwa nekukwira kwayo kupisa conductivity uye yakanakisa makemikari kuramba.Iwo anoshandiswa mukunyungudusa nekunyungudusa maitiro anosanganisira kupisa kwakanyanya, sekugadzirwa kweceramics uye alloys.
Imwe neimwe mhando yecrucible ine yayo yakasarudzika mabhenefiti uye mashandisirwo.Crucible kusarudzwa kunoenderana nezvinhu zvakaita sechinhu chiri kunyungudutswa kana kunyungudutswa, yaidiwa tembiricha renji uye bhajeti.Kunyangwe iwe uri kunyungudutsa mhangura, simbi yekukanda, kana kunyungudutsa alloys, kusarudza iyo chaiyo crucible yakakosha pakushanda kwakabudirira uye kwakanaka.
Muchidimbu, macrucibles anoita basa rakakosha mumaindasitiri akasiyana anosanganisira kunyungudika uye kunyungudika.Kunzwisisa mhando dzakasiyana dzemacrucibles anowanikwa uye mashandisirwo awo chaiwo anogona kubatsira mabhizinesi kuita sarudzo dzine ruzivo nezve crucible yekushandisa kuzadzisa zvavanoda.Ingave iri iron crucible, cast iron crucible, quartz crucible, porcelain crucible, corundum crucible, graphite crucible kana silicon carbide crucible, mhando yega yega ine zvayakanakira uye zvinogumira.Nekusarudza crucible chaiyo, mabhizinesi anogona kukwidziridza mashandiro awo uye nekuona mhedzisiro yemhando yepamusoro.
