Mchenga wa Quartz
Mchenga wa Quartz ndi mchere wachilengedwe womwe umapangidwa ndi silicon dioxide (SiO₂), wopangidwa ndi kuphwanya, kuyang'ana, ndi kukonza mwala wa quartz. Chifukwa cha kuuma kwake kwakukulu, kukhazikika kwa mankhwala, ndi kukana kutentha, amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana.

Mpikisano mwayi
Kampaniyo idachita kafukufuku wampikisano kuti adziwe zomwe zimachita bwino komanso zofooka zake poyerekeza ndi omwe amapikisana nawo.
Kulimba Kwambiri:
Mohs kuuma kwa 7, ndi kukana mwamphamvu kuvala.
01
Chemical Inertness:
Kusamva zidulo (kupatula hydrofluoric acid) ndi dzimbiri, kumachita pang'ono ndi mankhwala ambiri.
02
Msika waukulu
Kutentha Kwambiri: Malo osungunuka pafupifupi madigiri 1750 , oyenera{1}}malo otentha kwambiri.
03
Wangwiro mankhwala dongosolo
Insulation: Mphamvu zabwino kwambiri zamagetsi zamagetsi.
04
Zimagwira bwino ntchito-makatsatsa malonda
Mtundu & Fomu: Nthawi zambiri zoyera zoyera kapena zopanda mtundu zowonekera; zingawoneke zachikasu, zofiira, ndi zina zotero, pamene zonyansa zilipo.

Gulu & Mafotokozedwe
- Natural Quartz Sand
- High-Mchenga wa Purity Quartz
Mwa Kukula Kwakanthu
Zodziwika bwino
Mchenga wokhuthala:
- 4-6 mauna (4.75-3.35mm)
- 6-10 mauna (3.35-2mm)
- 10-20 mauna (2-0.85mm)
- Kugwiritsa ntchito: konkriti yomangira, zida zam'misewu, zosefera pamadzi, ndi zina.
01
Mchenga wapakatikati:
- 20-40 mauna (0.85-0.425mm)
- 40-70 mauna (0.425-0.212mm)
- Ntchito: kupanga magalasi, mchenga wotayira, zomatira, ndi zina zotero.
02
Mchenga wabwino:
- 70-140 mauna (0.212-0.106mm)
- 140-270 mauna (0.106-0.053mm)
- Ntchito: zoumba, zokutira, kusefera madzi, ndi zina zotero.
03
Mchenga wabwino kwambiri (ufa):
- 270-325 mauna (0.053-0.045mm)
- 325 mauna ndi kupitilira apo (＜0.045mm)
- Kugwiritsa ntchito: zida zamagetsi, zodzoladzola, zopangira mwaluso, ndi zina zotero.
04
Mapulogalamu
- Makampani agalasi:Zinthu zapakati pagalasi lathyathyathya ndi galasi lachidebe (zoposa 70% zakugwiritsa ntchito kwathunthu).
- Foundry:Mchenga wowumba-woponya zitsulo zotentha kwambiri.
- Kuchiza Madzi:Filtration medium kuchotsa zolimba zoyimitsidwa.
- Zamagetsi:Mchenga wapamwamba- wa silicon micro powder ndi zolongedza semiconductor.
- Makampani a Chemical:Asidi-zodzaza zosagwira, zonyezimira za ceramic.
- Zomangamanga:Mwala wochita kupanga, pansi screed, zomatira matailosi.
- Zina:Sandblasting, mabala a gofu, zopangira petroleum fracturing (utomoni-mchenga wokutidwa).
Njira Zopangira
1. Kukumba & Kuphwanya
2. Kuchapira/Kuthira kwa Acid
3. Kupatukana kwa Magnetic
4. Kuwunika
5. Kuwerengetsa/Kuyeretsa (mchenga{1}woyera kwambiri)
