Sulfur Hexafluoride (SF6)

Technical parameters

Sulfur hexafluoride, ine chimiro chemakemikari inonzi SF6, igasi risina ruvara, risina kunhuwa, risina chepfu, uye risingabatike. Sulfur hexafluoride ine gaseous pasi peyakajairika tembiricha uye kumanikidzwa, ine yakagadzikana makemikari zvimiro, zvishoma soluble mumvura, doro uye ether, soluble mu potassium hydroxide, uye haaite chemakemikari ne sodium hydroxide, liquid ammonia uye hydrochloric acid. Haiite nemhangura, sirivheri, simbi, uye aruminiyamu munzvimbo yakaoma iri pasi pe300 ° C. Pazasi pe500 ℃, haina mhedzisiro pane quartz. Inopindirana nesimbi yesodium pa250°C, uye inopindira mu liquid ammonia pa -64°C. Ichaora kana yakasanganiswa nehydrogen sulfide uye inopisa. Pa200 ℃, pamberi pemamwe masimbi akadai sesimbi nesilicon simbi, inogona kusimudzira kupera kwayo zvishoma nezvishoma. Sulfur hexafluoride chizvarwa chitsva che-ultra-high voltage insulating material, iyo inoshandiswa zvakanyanya kuisa gasi remagetsi, midziyo yemagetsi uye radar waveguides, uye sechinhu chinodzivirira chekudzima arc uye hukuru-hukuru hunoshandura mune high-voltage switch. Zvakanakira zveSF6 gasi-insulated pombi yekufambisa mitsara yakaderera dielectric kurasikirwa, yakakura kutapurirana simba, uye inogona kushandiswa mukudonha-kudonha. SF6 gasi insulated transformer ine zvakanakira moto uye kudzivirira kuputika. Sulfur hexafluoride ine hunhu hwekugadzikana kwekemikari yakanaka uye isiri-corrosion kumidziyo. Inogona kushandiswa sefiriji muindasitiri yefiriji (kushanda tembiricha pakati -45 ~ 0 ℃). Electronic giredhi yakakwira-kuchena sarufa hexafluoride yakanaka yemagetsi etchant, iyo inoshandiswa zvakanyanya mumunda weiyo microelectronics tekinoroji seplasma etching uye yekuchenesa mumiriri mukugadzira mahombe akabatanidzwa akadai semachipisi emakombuta uye liquid crystal skrini. Chengetedzo yekuchengetedza: Chengetedza muimba inotonhorera, ine mhepo yekuchengetera mhepo. Ramba kure nemoto nekupisa. Tembiricha yekuchengetera haifanirwe kudarika 30°C. Inofanirwa kuchengetwa zvakasiyana kubva nyore (zvinopisa) zvinopisa uye oxidants, uye kudzivirira zvakasanganiswa kuchengetedza. Nzvimbo yekuchengetera inofanirwa kunge yakashongedzerwa neyakadonha yekurumidzira kurapwa michina.

Application:

① Dielectric yepakati:

SF6 inoshandiswa muindasitiri yemagetsi segasi dielectric svikiro kune yakakwira-voltage circuit breakers, switchgear, uye zvimwe midziyo yemagetsi, kazhinji ichitsiva oiri yakazadzwa macircuit breakers (OCBs) anogona kuve nePCB inokuvadza.

②Kushandiswa kwekurapa:

SF6 inoshandiswa kupa tamponade kana plug yegomba retinal mune retinal detachment kugadzirisa mashandiro nenzira yebubble gasi.

③Tracer compound:

SF6 inoshandiswa kupa tamponade kana plug yegomba retinal mune retinal detachment kugadzirisa mashandiro nenzira yebubble gasi.
