FAQ
Q1: O le a le lelei o faʻamau faʻapipiʻi graphite silicon carbide pe a faʻatusatusa i faʻamau graphite masani?
✅Tete'e maualuga o le vevela: E mafai ona tatalia 1800 ° C umi ma 2200 ° C taimi pupuu (vs. ≤1600 ° C mo graphite).
✅Umi Olaga: 5x sili atu tete'e te'i vevela, 3-5x umi le ola auaunaga averesi.
✅Le Fa'aleaga: Leai se carbon penetration, faʻamautinoa le mama uʻamea uʻamea.
Q2: O a u'amea e mafai ona liusuavai i totonu o nei u'amea?
▸Metala masani: Alumini, kopa, zinc, auro, siliva, ma isi.
▸Metala Reactive: Lithium, sodium, calcium (e manaʻomia le Si₃N₄ coating).
▸Metala Fa'amumu: Tungsten, molybdenum, titanium (e manaʻomia le gaogao / kasa inert).
Q3: E mana'omia e ni fa'amea fou fou se togafiti a'o le'i fa'aogaina?
Taofi Fa'atonu: Fa'asa lemu i le 300°C → taofi mo le 2 itula (ave'ese le susū o totoe).
Fautuaga Fa'ase'e Muamua: Fa'amuta muamua se vaega o mea fa'ameamea (fa'atupu se vaega puipui).
Q4: E faʻafefea ona puipuia le taʻe o ipu?
Aua ne'i fa'atumuina mea malulu i totonu o se ko'i vevela (max ΔT <400°C).
Fualuga malulu pe a uma ona liusuavai <200°C/itula.
Fa'aaoga ni togo fa'atau (aloese mai le a'afiaga fa'ainisinia).
Q5: E fa'afefea ona puipuia le ta'e o ipu?
Aua ne'i fa'atumuina mea malulu i totonu o se ko'i vevela (max ΔT <400°C).
Fualuga malulu pe a uma ona liusuavai <200°C/itula.
Fa'aaoga ni togo fa'atau (aloese mai le a'afiaga fa'ainisinia).
Q6: O le a le fa'atonuga aupito maualalo (MOQ)?
Fa'ata'ita'iga Tulaga: 1 fasi (faʻataʻitaʻiga avanoa).
Fuafuaga Fa'apitoa: 10 fasi pepa (ata CAD e manaʻomia).
Q7: O le a le taimi e ta'imua ai?
⏳Meatotonu o lo'o i totonu: Va'a i totonu ole 48 itula.
⏳Poloaiga Fa'aleaganu'u: 15-25asomo le gaosiga ma le 20 aso mo le faʻafefe.
Q8: E fa'afefea ona iloa pe ua le manuia se fagu?
Ta'eta'ei > 5mm ile puipui totonu.
Le loloto o le u'amea > 2mm.
Deformation> 3% (fua suiga o le lautele fafo).
Q9: E te tu'uina atu ta'iala ile fa'agasologa ole liusuavai?
Fa'avevela pi'o mo metala eseese.
Fua fua faatatau o le tafe o kasa.
