Gulu ndi ubwino wa crucibles

Ma Cruciblesndi zida zofunika m'mafakitale osiyanasiyana pothandizira kusungunula ndi kusungunula. Ndi chidebe chomwe chimatha kupirira kutentha kwambiri ndipo chimagwiritsidwa ntchito kusunga zinthu ndikuzitenthetsa mpaka kusungunuka. Mitundu yosiyanasiyana ya crucibles imagwiritsidwa ntchito malinga ndi zofunikira zenizeni za zinthu zomwe zimasungunuka kapena kusungunuka. Mu positi iyi ya blog, tiwona mitundu yosiyanasiyana ya ma crucibles ndi ntchito zawo.

 1. Chitsulo chachitsulo:

 Gwiritsani ntchito chitsulo chachitsulo posungunula zinthu zamphamvu zamchere monga NaOH. Komabe, sichinagwiritsidwe ntchito kwambiri chifukwa cha zovuta monga dzimbiri zosavuta komanso makutidwe ndi okosijeni. M'magwiritsidwe ambiri okhudzana ndi zinthu zamchere, zitsulo zachitsulo zopanda inert zimakhalabe zomwe amakonda.

 2. Chitsulo chachitsulo:

 Ma crucibles achitsulo amapangidwa kuchokera ku chitsulo cha nkhumba ndipo amadziwika kuti ndi olimba. Amagwiritsidwa ntchito kusungunula ma aloyi azitsulo osiyanasiyana kuphatikiza aluminium, zinki, lead, malata ndi ma antimoni. Poyerekeza ndi zitsulo zachitsulo, zitsulo zachitsulo zimakhala zolimba kwambiri ndipo zimatha kupirira kutentha kwakukulu komwe kumafunika kusungunula zitsulozi.

 3. Mtsuko wa Quartz:

 Ma quartz crucibles amagwiritsidwa ntchito kwambiri pamakampani opanga ma semiconductor ndipo ndi ofunikira kuti apange mabwalo akuluakulu ophatikizika. Ma crucibles awa amatha kupirira kutentha mpaka madigiri 1650 ndipo amapezeka m'mawonekedwe omveka bwino komanso osawoneka bwino. Translucent quartz crucible yopangidwa ndi njira ya arc, yomwe imagwiritsidwa ntchito kukoka silikoni yayikulu yayikulu imodzi. Lili ndi ubwino wa chiyero chapamwamba, kukana kutentha kwamphamvu, kukula kwakukulu, kulondola kwambiri, ntchito yabwino yotetezera kutentha, kupulumutsa mphamvu, ndi khalidwe lokhazikika. Komabe, chisamaliro chiyenera kutengedwa chifukwa quartz ndi yofewa ndipo imatha kusweka mosavuta.

 4. Choumba chadothi:

 Ma crucibles a ceramic ndi otchuka chifukwa cha kukana kwawo kwamankhwala komanso kukwanitsa. Komabe, sizingagwiritsidwe ntchito kusungunula zinthu zamchere monga NaOH, Na2O2, Na2CO3, ndi zina zotero, chifukwa zimachita ndi porcelain ndikuyambitsa dzimbiri. Kuphatikiza apo, ma porcelain crucibles sayenera kukhudzana ndi hydrofluoric acid. Ndioyenera kugwiritsidwa ntchito kutentha pafupifupi madigiri 1200.

 5. Corundum crucible:

 Corundum crucible ndiyoyenera kwambiri kusungunula zitsanzo pogwiritsa ntchito zinthu zofooka zamchere monga anhydrous Na 2 CO 3 ngati flux. Komabe, sizoyenera kusungunula zitsanzo pogwiritsa ntchito zinthu zamchere kwambiri (monga Na2O2, NaOH) kapena zinthu za acidic (monga K2S2O7) monga ma fluxes.

 6. graphite crucible:

 Ma graphite crucibles amagwiritsidwa ntchito kwambiri mumakampani opangira zitsulo chifukwa champhamvu kwambiri yamatenthedwe komanso kukana kutentha kwambiri. Ndioyenera kusungunula zitsulo zosiyanasiyana kuphatikizapo mkuwa, golide, siliva ndi mkuwa.

 7. Silicon carbide crucible:

 Ma silicon carbide crucibles amadziwika chifukwa cha kutentha kwawo kwakukulu komanso kukana kwambiri kwamankhwala. Amagwiritsidwa ntchito posungunula ndi kusungunula pogwiritsa ntchito kutentha kwakukulu, monga kupanga zitsulo za ceramic ndi alloys.

 Mtundu uliwonse wa crucible uli ndi ubwino wake ndi ntchito zake. Kusankhidwa kwa crucible kumadalira zinthu monga zinthu zomwe zimasungunuka kapena kusungunuka, kutentha komwe mukufuna komanso bajeti. Kaya mukusungunula mkuwa, chitsulo chosungunula, kapena zitsulo zosungunula, kusankha crucible yoyenera ndikofunikira kuti ntchitoyo ikhale yopambana komanso yogwira mtima.

 Mwachidule, ma crucibles amagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana okhudza kusungunula ndi kusungunula. Kumvetsetsa mitundu yosiyanasiyana ya ma crucibles omwe alipo komanso momwe angagwiritsire ntchito kungathandize mabizinesi kupanga zisankho zanzeru pazomwe angagwiritse ntchito kukwaniritsa zosowa zawo. Kaya ndi chitsulo, chitsulo chachitsulo, quartz crucible, porcelain crucible, corundum crucible, graphite crucible kapena silicon carbide crucible, mtundu uliwonse uli ndi ubwino wake ndi zolephera. Posankha crucible yoyenera, mabizinesi amatha kukulitsa ntchito zawo ndikuwonetsetsa kuti ali ndi zotsatira zabwino kwambiri.
