Chii ichi chinyorwa?
Carbon tetrafluoride igasi risina ruvara, risinganhuhwi patembiricha yakajairwa uye kudzvanywa. Iyo yakanyanya makemikari inert nekuda kweiyo yakasimba kabhoni-fluorine zvisungo. Izvi zvinoita kuti isaite-reactive nezvinhu zvakajairika pasi pemamiriro akajairika. CF4 igasi rine simba regreenhouse, rinokonzera kudziya kwepasi rose.
Ndekupi kushandisa zvinhu izvi?
1. Semiconductor Manufacturing: CF4 inoshandiswa zvakanyanya muindasitiri yemagetsi yeplasma etching uye chemikemikari vapor deposition (CVD) maitiro. Inobatsira mukunyatso etching yesilicon wafers uye zvimwe zvinhu zvinoshandiswa semiconductor zvishandiso. Iyo inertness yekemikari yakakosha mukudzivirira maitiro asingadiwe panguva idzi maitiro.
2. Dielectric Gas: CF4 inoshandiswa se dielectric gasi mu-high-voltage magetsi emagetsi uye gas-insulated switchgear (GIS). Yayo yakakwirira dielectric simba uye yakanakisa magetsi insulating zvivakwa inoita kuti ive yakakodzera kushandiswa mune izvi maapplication.
3. Refrigeration: CF4 yave ichishandiswa sefiriji mune mamwe epasi-tembiricha zvikumbiro, kunyangwe kushandiswa kwayo kwakadzikira nekuda kwekunetseka kwezvakatipoteredza pamusoro pekupisa kwayo kwakanyanya kwepasirese.
4. Tracer Gasi: Inogona kushandiswa seyekutsvagisa gasi mumatanho ekuona kudonha, kunyanya pakuona kuvuza mune yakakwira-vacuum masisitimu uye midziyo yemuindasitiri.
5. Calibration Gasi: CF4 inoshandiswa seyakagadziriswa gasi mune gasi analyzers uye gasi detectors nekuda kweiyo inozivikanwa uye yakagadzikana zvinhu.
6. Tsvagiridzo neKuvandudza: Inoshandiswa mukutsvagisa nekuvandudza murabhoritari kune zvinangwa zvakasiyana, zvinosanganisira zvinhu zvesainzi, kemisitiri, uye kuyedza fizikisi.
Ziva kuti mashandisirwo chaiwo uye mirau yekushandiswa kwechinhu ichi / chigadzirwa chinogona kusiyana nenyika, indasitiri uye chinangwa. Gara uchitevera mirairo yekuchengetedza uye bvunza nyanzvi usati washandisa chinhu ichi / chigadzirwa mune chero application.
