Kupatsanura uye kushandiswa kwehupfu hwe quartz

1. Nhanganyaya
Jecha requartz rakanatswa, upfu hwequartz, rinoshandiswa pakugadzira matombo equartz akachena zvakanyanya, chigadzirwa chacho chine giredhi repamusoro (SiO2=99.82%, Fe2O3=0.37, Al2O3=0.072, CaO=0.14), ruvara ruchena, kuomarara kwakasimba (Mohs madhigirii manomwe kana kupfuura).
Jecha re quartz rakanaka rinogezwa, rinopwanywa uye rinonamirwa muzvikamu zvakasiyana-siyana zvejecha re quartz, uye upfu hwe quartz hunogadzirwa hune kutsetseka kwakasiyana uye hutete hwema mesh anopfuura 300. Mashandisirwo makuru ejecha re quartz rakanaka: kune zve ceramics, enamel, precision modeling, chemical, pendi, zvinhu zvekuvaka, metallurgy, advanced glass, metal rust removal, polishing, water treatment nevamwe vashandisi kupa zvinhu zvisina kugadzirwa uye zvimwe zvekubatsira. Hunhu hukuru hwejecha re quartz rakanaka: 0.6-1.2 1-2 2-4 4-8 8-16mm particle size. (Inogona kugadzirwa zvichienderana nezvinodiwa nevatengi) quartz powder (ine quartz jecha), inozivikanwawo sesilicon powder. Jecha re quartz iminerali yakasimba, inodzivirira kupfeka, ine makemikari yakasimba, mineral composition yayo huru iSiO2, quartz jecha ruvara ruchena semukaka, kana kuti isina ruvara, kuomarara 7, brittle no cleavage, shell break, grease luster, density ye 2.65, bulk density (20-200 mesh i1.5). Hunhu hwayo hwemakemikari, hwekupisa uye hwemakanika hune hunhu hwakajeka hwe anisotropy, hahunyungudike muasidhi, hunonyungudika zvishoma muKOH solution, nzvimbo yekunyungudika ye1650℃.

2. Kupatsanurwa kweupfu hwe quartz

Hupfu hwe quartz yeindasitiri (jecha) hunowanzo kamurwa kuita: jecha re quartz rakajairika (hupfu), jecha re quartz rakacheneswa, jecha re quartz rakachena kwazvo, jecha re quartz rakanyungudutswa uye upfu hwe silica.

Jecha re quartz (upfu) rakajairika: SiO2≥90-99%Fe2O3≤0.06-0.02%, kusimba kwe 1750–1800℃, chitarisiko chezvimwe zvidimbu zvikuru, pamusoro payo pane kapusule yeganda yeyero. Saizi yezvikamu iri pakati pe 1-320 mesh, inogona kugadzirwa zvichienderana nezvinodiwa nemushandisi. Mashandisirwo makuru: simbi, inki silicon carbide, zvinhu zvekuvaka, enamel, simbi yakaumbwa, firita, furo alkali, indasitiri yemakemikari, sandblasting nedzimwe indasitiri.

Jecha re quartz rakanatswa (upfu): inozivikanwawo sejecha re quartz rakagezwa neasidhi, SiO2≥99-99.5%Fe2O3≤0.02-0.015%, yakasarudzwa matombo emhando yepamusoro ekugadzirisa zvakaoma. Hukuru hwezvikamu zve 1-380 mesh, inogona kugadzirwa zvichienderana nezvinodiwa nemushandisi, chitarisiko chechena kana chekristaro. Mashandisirwo makuru: zvinhu zvekusefa, girazi repamusoro-soro, zvigadzirwa zvegirazi, zvinhu zvinoramba, matombo anonyunguduka, kukanda kwakanyatsogadzirwa, kuputira sandblasting, zvinhu zvekukuya mavhiri, nezvimwewo.

Jecha re quartz rakachena kwazvo (upfu): SiO2≥99.5-99.9%Fe2O2≤0.005%, kushandiswa kwekristaro yechisikigo yemhando yepamusoro 1-3, yakasarudzwa nokungwarira, yakagadziriswa zvakanaka. Saizi yezvikamu 1-0.5mm, 0.5-0.1mm, 0.1-0.01mm, 0.01-0.005mm, inogona kugadzirwa zvichienderana nezvinodiwa nemushandisi. Mashandisirwo makuru: girazi repamusoro-soro, electronic filler, melting stone, precision casting, chemical industry, ceramics nezvimwewo.

Upfu hwesilica: SiO2:99.5%min-99.0%min, 200-2000 mesh, chitarisiko cheupfu chena chegrey kana grey, refractoryness >1600℃, huremu hwehukuru :200~250 kg/cubic meter.

3. Munda wekushandisa weupfu hwe quartz
Upfu hweQuartz hunoshandiswa zvakasiyana-siyana nekuda kwekuchena kwayo kwakanyanya, kusachena uye simbi shoma. Girazi: Zvinhu zvikuru zvakagadzirwa negirazi rakatsetseka, girazi rinoyangarara, zvigadzirwa zvegirazi (majagi egirazi, mabhodhoro egirazi, machubhu egirazi, nezvimwewo), girazi re optical, fiber yegirazi, zvishandiso zvegirazi, girazi rinofambisa mhepo, jira regirazi uye girazi re anti-ray rakakosha.
Zviumbwa zvesimbi nezvinhu zvinodzivirira: porcelain embryo neglaze, high silicon brick yekubikira, silicon brick yakajairika nesilicon carbide nezvimwe zvinhu zvakagadzirwa.

Kuvaka: kongiri, zvinhu zvinosimbisa simende, zvinhu zvekuvaka migwagwa, marble wekugadzira, zvinhu zvekuedza zvesimende (kureva, jecha resimende), nezvimwewo.
Indasitiri yemakemikari: zvinhu zvakagadzirwa zvakaita sesilicon compounds negirazi remvura, kuzadza sulfuric acid tower, amorphous silica powder.
Michina: Zvinhu zvikuru zvinoshandiswa pakukanda jecha, zvinhu zvekukuya (jecha rinoputika, bepa rekukuya rakaoma, sandpaper, jira reemery, nezvimwewo).
Zvemagetsi: silicon yesimbi yakachena kwazvo, fiber yekutaurirana, nezvimwewo.
Rabha, purasitiki: zvinozadza (zvinogona kuvandudza kuramba kupfeka).
