FAQ
Q1: He aha nga painga o nga raima graphite silicon carbide ki te whakataurite ki nga graphite crucibles tuku iho?
✅Te Paemahana Nui ake: Ka taea te tu ki te 1800°C mo te wa roa me te 2200°C mo te wa poto (vs. ≤1600°C mo te graphite).
✅Roa Te Ora: 5x te pai ake o te awangawanga waiariki, 3-5x te roa o te oranga ratonga.
✅Kore Whakakino: Karekau he urunga waro, e whakarite ana i te parakore whakarewa.
Q2: Ko wai nga konganuku ka taea te rewa i roto i enei parapara?
▸Nga konganuku noa: Konumohe, parahi, konutea, koura, hiriwa, etc.
▸Nga konganuku tauhohenga: Lithium, konutai, konupūmā (e hiahia ana ki te paninga Si₃N₄).
▸Nga Konanuku Whakawera: Tungsten, molybdenum, titanium (e hiahia ana ki te hau korehau/kore).
Q3: Ka hiahia nga parapara hou ki te maimoatanga i mua i te whakamahi?
Te tunu tunu: Kia ata whakamahana ki te 300°C → pupuri mo te 2 haora (ka tangohia te toenga makuku).
Tohutohu Whakarewa Tuatahi: Whakarewahia te puranga o nga rawa i te tuatahi (ka hanga he paparanga whakamarumaru).
Q4: Me pehea te aukati i te pakaru o te pakaru?
Kaua rawa e utaina he rawa matao ki roto i te ipu wera (te teitei ΔT <400°C).
Reiti whakamahana i muri i te whakarewatanga <200°C/haora.
Whakamahia he kokopi para i whakatapua (kaore i te pa ki te miihini).
Q5: Me pehea te aukati i te pakaru o te parapara?
Kaua rawa e utaina he rawa matao ki roto i te ipu wera (te teitei ΔT <400°C).
Reiti whakamahana i muri i te whakarewatanga <200°C/haora.
Whakamahia he kokopi para i whakatapua (kaore i te pa ki te miihini).
Q6: He aha te rahinga tono iti (MOQ)?
Tauira Paerewa: 1 wahi (nga tauira e waatea ana).
Nga Hoahoa Ritenga: 10 nga waahanga (he tuhi CAD e hiahiatia ana).
Q7: He aha te wa arahi?
⏳Nga Taonga Taonga: Ka tukuna i roto i nga haora 48.
⏳Nga Ota Ritenga: 15-25nga ramo te hanga me te 20 ra mo te pokepokea ai.
Q8: Me pehea te whakatau mena kua rahua te parapara?
Kapiti > 5mm ki runga pakitara o roto.
Te hohonutanga o te whakauru whakarewa> 2mm.
Hurihanga> 3% (ine i te huringa diameter o waho).
Q9: Kei te whakarato koe i te arataki tukanga whakarewa?
Nga pihi whakawera mo nga konganuku rereke.
Te tātaitai tere rere hau.
Nga akoranga ataata tango para.
