Izinto ze-quartz ezihlanganisiwe kugobolondo lokutshala imali emazweni athuthukile zilokhu zikhula unyaka nonyaka, ikakhulukazi kugobolondo le-silica sol mold on surface layer has a lot of experience.Qhathanisa nentengo kanye nokusetshenziswa kwempahla ye-zirconium yenze intuthuko enkulu, Kuyizinto ezisetshenziswayo zobunjiniyela ezifanele njengamanje.
Imikhiqizo ye-quartz ehlanganisiwe ikhethwa izinto zokusetshenziswa ze-silica zekhwalithi ephezulu [sio2>99%], ezincibilika esithandweni se-arc noma esithandweni sokumelana, ekushiseni okuphezulu kwe-1695-1720 ℃.Ngenxa ye-viscosity ephezulu ye-sio2 melt, engu-10 ^ 7 Pa·s at 1900℃, ayikwazi ukubunjwa ngendlela yokusakaza.Ngemuva kokupholisa, iyi-vitreous futhi ingasetshenziswa njengempahla eluhlaza emikhiqizweni eshisiwe noma engashiswanga.I-Silica e-Fused ibonakala ngokumelana nokushaqeka okuhle kakhulu kwe-thermal, i-thermal conductivity ephansi, i-coefficient encane yokwandisa, ukumelana nokushisa okuphezulu emikhiqizweni ye-ceramic kanye nezinto eziphikisayo.Ngakho inokuqina okuphezulu kakhulu kwe-thermal.Ngakho-ke, ohlelweni lokugazinga nokuthulula igobolondo le-quartz elincibilikisiwe alivamile ukuphuka ngenxa yokushisa okukhulu, Kuyimpahla efanelekile ekubumbeni kokubunjwa kwe-investment casting refractory, futhi ingasetshenziswa njenge-surface layer noma i-back layer coating refractory materials.
Imikhiqizo yethu ye-silica ehlanganisiwe isetshenziswa kakhulu ekubunjweni okunembayo, i-quartz ceramic roller embonini yengilazi, izinto eziphikisayo, izinto zokusetshenziswa ze-ceramic, izinto zokusetshenziswa zengilazi, i-epoxy resin casting, izinto zokuvalwa kwe-elekthronikhi, umthombo wokukhanya kagesi, ezokwelapha, ukusakaza, nezinye izimboni. izinto zokusetshenziswa eziyinhloko, futhi nakupende, ukunamathela nezinye izinto ezifanelekile zokugcwalisa imboni yamakhemikhali.
Okuqukethwe kokuhlanzeka kwe-Sio2 kwequartz ehlanganisiwe: okuqukethwe kwe-Sio2 kwe-Fused silica A grade akufanele kube ngaphansi kuka-99.95%, ibanga B akufanele libe ngaphansi kuka-99.8%, futhi ibanga C akufanele libe ngaphansi kuka-99%
