Ikhwalithi Kuqala! I-Zhongqi Silicon Isungula Uhlelo Lokulawula Ikhwalithi Lwenqubo Ephelele Ukuze Iqinisekise Ukuthobela Okuzinzile Kweqembu Ngalinye

Kwadalwa ngo 07.09

Njengomkhiqizi oholayo ochwepheshile we-silicon dioxide yezinga lokudla eChina, iZhongqi Silicon ihlale ithatha ikhwalithi yomkhiqizo njengomgogodla webhizinisi. Ukuqinisekisa ukuzinza kwekhwalithi ye-ZLSILW58BF ultra-low iron silicon dioxide, inkampani isungule uhlelo oluphelele lokulawula ikhwalithi oluhlanganisa 'ukungena kwezinto ezingavuthiwe - inqubo yokukhiqiza - ukulethwa komkhiqizo ophelile'.

Umdwebo wohlelo lokuvala umjikelezo olawula ikhwalithi ye-Zhongqi Silicon yensimbi ye-ZLSILW58BF ene-iron ephansi kakhulu

Emuva ekulawuleni kwezinto zokusetshenziswa, i-Zhongqi Silicon isungule ubambiswano olukhethekile lwecebo nomhlinzeki oyedwa wasekhaya we-quartz sand wezinga le-semiconductor. Yonke iqoqo lezinto zokusetshenziswa kufanele lidlule ekuhlolweni okungu-12, futhi izinto ezinokuthi i-iron content ingaphezu kuka-20ppm ziyenqatshwa ngqo. Emuva ekulawuleni ukukhiqiza, kusetshenziswa uhlelo lwe-DCS olulawula ngokuzenzakalelayo ukuqapha amapharamitha angu-28 abalulekile enqubweni, njengezinga lokushisa lokuphendula, i-pH value, nesivinini sokuxuba, ngesikhathi sangempela esilinganiselwe ku-millisecond, futhi noma yikuphi ukuphambuka kwepharamitha kuzokhipha i-alamu ngokuzenzakalelayo.

Uhlelo lokuzenzakalela lwe-DCS lwe-Zhongqi Silicon luqapha amapharamitha angu-28 abalulekile okukhiqiza ngesikhathi sangempela

Esigabeni sokuhlola umkhiqizo ophelile, inkampani itshale imali eyizigidi eziyi-15 zamaRandi aseChina ukwakha isikhungo sokuhlola esiqinisekisiwe se-CNAS esihamba phambili embonini, esihlome ngemishini ethuthukisiwe efana ne-inductively coupled plasma optical emission spectrometer (ICP-OES), i-atomic absorption spectrometer (AAS), ne-laser particle size analyzer. Yonke ibhetshi yemikhiqizo ye-ZLSILW58BF kumele idlule ekuhloleni okuqinile okulandelayo:

Isikhungo sokuhlola esiqinisekiswe yi-CNAS se-Zhongqi Silicon esinemishini ye-ICP-OES kanye ne-laser particle size analyzer

• Izinga lensimbi: Inembile ezingeni lika-0.1ppm, iqinisekisa ukuthi ≤100ppm

• Izinga le-silicon dioxide: ≥99.0% (ngemva kokuvutha)

• Izinsimbi ezinzima: Umthofu ≤1mg/kg, i-arsenic ≤2mg/kg, i-mercury ≤1mg/kg

• Amagciwane: Inani eliphelele lamagciwane ≤30CFU/g, isikhunta nemvubelo <10CFU/g

• Izinkomba zomzimba namakhemikhali: Ukulahlekelwa kokomisa, ukulahlekelwa kokusha, inani le-pH, inani lokumunca uwoyela, indawo ethile yobuso, njll.

"Izinga lethu lekhwalithi lithi 'yonke ibhetshi iyafana,'" kusho uMqondisi Wekhwalithi we-Zhongqi Silicon. "I-ZLSILW58BF isebenzisa 'uhlelo lokuhlola kabili.' Ngaphandle kokuhlolwa kwangaphakathi efektri, ibhetshi ngayinye yemikhiqizo kufanele ithunyelwe esikhungweni esigunyaziwe somuntu wesithathu ukuze ihlolwe ngaphambi kokuphuma efektri. Siyathembisa ukuthi okuqukethwe kwe-iron kunoma iyiphi ibhetshi yemikhiqizo ngeke kudlule i-100ppm, futhi inani elijwayelekile lizinzile cishe ku-50ppm."
