Ukuhlelwa kunye neenzuzo ze-crucibles

Iminqamlezozizixhobo ezibalulekileyo kumashishini ahlukeneyo okuphatha iinkqubo zokunyibilika kunye nokunyibilikisa. Sisikhongozeli esikwaziyo ukumelana namaqondo obushushu aphezulu kwaye sisetyenziselwa ukubamba izinto kunye nokuzifudumeza ukuya kwindawo yazo yokunyibilika. Iindidi ezahlukeneyo ze-crucibles zisetyenziselwa ngokuxhomekeke kwiimfuno ezithile zezinto ezincibilikayo okanye ezincibilikayo. Kule post blog, siza kuphonononga iintlobo ezahlukeneyo ze-crucibles kunye nezicelo zabo.

 1. Intsimbi yentsimbi:

 Sebenzisa i-iron crucible xa unyibilikisa izinto ezinamandla ze-alkaline ezifana ne-NaOH. Nangona kunjalo, ayizange isetyenziswe ngokubanzi ngenxa yeengxaki ezifana nokurusa okulula kunye ne-oxidation. Kwiinkqubo ezininzi ezibandakanya izinto ze-alkaline, ii-crucibles zetsimbi ze-inert zihlala zikhethiweyo.

 2. Intsimbi yentsimbi:

 Iintsimbi ezenziwe ngentsimbi zenziwe ngentsimbi yehagu kwaye zaziwa ngokuqina kwazo. Isetyenziselwa ukunyibilikisa iialloyi zetsimbi ezahlukeneyo ezibandakanya ialuminiyam, i-zinc, ilothe, i-tin kunye nealloyi ze-antimony. Xa kuthelekiswa neentsimbi zentsimbi, i-cast iron crucibles yomelele kwaye inokumelana nokushisa okuphezulu okufunekayo ukunyibilikisa ezi ngxube.

 3. I-Quartz crucible:

 I-Quartz crucibles isetyenziswa ngokuqhelekileyo kwishishini le-semiconductor kwaye iyimfuneko kwimveliso yeesekethe ezinkulu ezidibeneyo. Ezi crucibles ziyakwazi ukumelana namaqondo okushisa ukuya kwii-degrees ze-1650 kwaye zifumaneka kwiinguqulelo ezicacileyo kunye ne-opaque. Icrucible quartz crucible eyenziwe ngendlela ye-arc, esetyenziselwa ukutsalwa kwesilicon yekristale enkulu. Ineenzuzo zokucoceka okuphezulu, ukumelana nobushushu obuqinileyo, ubungakanani obukhulu, ukuchaneka okuphezulu, ukusebenza kakuhle kokufakwa kwe-thermal, ukonga amandla, kunye nomgangatho ozinzile. Nangona kunjalo, kufuneka kuthathelwe ingqalelo njengoko i-quartz i-brittle kwaye inokuphuka lula.

 4. I-porcelain crucible:

 Iziqwenga zeCeramic zithandwa ngenxa yokuchasana kweekhemikhali kunye nokufikeleleka. Nangona kunjalo, ayinakusetyenziselwa ukunyibilikisa izinto ze-alkaline ezifana ne-NaOH, i-Na2O2, i-Na2CO3, njl., kuba ziya kusabela nge-porcelain kwaye zibangele ukubola. Ukongezelela, i-porcelain crucibles akufanele idibane ne-hydrofluoric acid. Zikulungele ukusetyenziswa kumaqondo obushushu ajikeleze i-1200 degrees.

 5. I-Corundum crucible:

 I-Corundum crucible ifaneleke kakhulu kwiisampuli ezinyibilikayo zisebenzisa izinto ezibuthathaka ze-alkaline ezifana ne-anhydrous Na 2 CO 3 njenge-flux. Nangona kunjalo, azifanelekanga ukunyibilika iisampulu zisebenzisa izinto ze-alkaline ezinamandla (ezifana ne-Na2O2, i-NaOH) okanye izinto ezine-acidic (ezifana ne-K2S2O7) njenge-fluxes.

 6. Icrucible yegraphite:

 I-Graphite crucibles isetyenziswa ngokubanzi kwi-industry casting metal ngenxa ye-conductivity ephezulu ye-thermal kunye nokumelana nokushisa okuphezulu. Zifanele ukunyibilika iintlobo ngeentlobo zesinyithi kuquka ubhedu, igolide, isilivere nobhedu.

 7. I-silicon ye-carbide crucible:

 I-silicon carbide crucibles iyaziwa ngokuba yi-conductivity ephezulu ye-thermal kunye nokuchasana kweekhemikhali. Zisetyenziselwa ukunyibilika kunye neenkqubo zokunyibilikisa ezibandakanya ukusetyenziswa kobushushu obuphezulu, njengokuveliswa kweeseramikhi kunye ne-alloys.

 Uhlobo ngalunye lwe-crucible lunenzuzo yalo ekhethekileyo kunye nezicelo. Ukukhethwa kwe-Crucible kuxhomekeke kwizinto ezifana nezinto ezincibilikayo okanye ezincibilikayo, uluhlu olufunwayo lobushushu kunye nohlahlo lwabiwo-mali. Ingaba unyibilikisa ubhedu, isinyithi esityhidiweyo, okanye i-alloys enyibilikayo, ukukhetha i-crucible efanelekileyo kubalulekile ekusebenzeni okuyimpumelelo kunye nokusebenza kakuhle.

 Isishwankathelo, ii-crucibles zidlala indima ebalulekileyo kumashishini ahlukeneyo abandakanya ukunyibilika kunye neenkqubo zokunyibilikisa. Ukuqonda iintlobo ezahlukeneyo ze-crucibles ezikhoyo kunye nezicelo zabo ezithile zinokunceda amashishini enze izigqibo ezinolwazi malunga nokuba yeyiphi i-crucible yokusebenzisa ukuhlangabezana neemfuno zabo ezithile. Ingaba i-iron crucible, i-cast iron crucible, i-quartz crucible, i-porcelain crucible, i-corundum crucible, i-graphite crucible okanye i-silicon carbide crucible, uhlobo ngalunye lunenzuzo kunye nemida yalo. Ngokukhetha i-crucible efanelekileyo, amashishini anokwandisa ukusebenza kwawo kwaye aqinisekise iziphumo ezikumgangatho ophezulu.
