FAQ
Q1: Waa maxay heerkulka ugu badan ee weelka Kjeldahl quartz uu u adkeysan karo?
J: Ilaa 1,200 digrii , laakiin isticmaalka dheeraadka ah ee ka sarreeya 1,000 digrii wuxuu yarayn karaa cimriga.
Q2: Ma lagu isticmaali karaa hydrofluoric acid (HF)?
J: Maya, HF waxay milmaan quartz. Isticmaal PTFE ama weelasha platinum ee dheefshiidka HF.
Q3: Maxaad quartz uga doorataa muraayadda borosilicate?
J: Quartz waxa uu leeyahay iska caabin shoog kulaylka sare leh, adkaysi kiimikaad oo wanaagsan, iyo nadiifnimo sare.
Q4: Waa maxay cabbirada la heli karo?
A: Cabbirrada caadiga ah: 50ml, 100ml, 250mL, 500ml, 1000mL (xajmiga gaarka ah ayaa la heli karaa marka la codsado).
