Sulfa chisvomukati chisiri chezvinhu nemakemikari Symbol sign s uye nhamba yeatomu yegumi nematanhatu Sulemental Sarufa haina kujekesa mumvura, zvishoma zvinyoro-nyoro mu ethanol, uye nyore nyore kuwanda muBarbon Dishidecs2.
1.PHYSTICAL ZVESE
- Sulfa kazhinji kiriviki yero, isina kunaka uye isina kunaka.
- Sarufa ine vazhinji vemubvumiri, zvese izvo zvinoumbwa s8cyclic mamorekuru. Izvo zvinonyanya kuzivikanwa ndezvekushandisa
- Orthorhombic Sarufa fomu yakagadzikana yeSarufa, uye painenge ichipiswa kusvika zana ° C, inogona kutonhorera kuti iwane monclinic sarufa. Iyo tembiricha yekushambadzira pakati peOrthorhombic sarufa ndeye 95.6 ° C.orhombich Sulfa ndiyo chete yakagadzikana fomu yeSulfu pamhepo tembiricha. Yayo yakachena fomu ndeye yero-yakasvibira (iyo sarufa inotengeswa pamusika inoonekwa yakawanda yero nekuda kwekuvapo kwekutengesa huwandu hweCyclophptasulfur). Orthorhombic sarufa zvechokwadi inoshambadza mumvura, ine murombo wekudyidzana, ishoko rakanaka remagetsi.
- Monclinic Sulfa ndiyo isingaverengeki sindano-sekristasi yakasara pamusoro mushure mekunyungudika sarufa uye kudurura kubva kune yakawandisa mvura. Monoclinic Sulfu orthorhombic sarufa akasiyana-siyana elemental sarufa edzimba dzakasiyana. Monclinic Sarufa chete yakagadzikana pamusoro 95.6 ℃, uye pakupisa, iyo zvishoma nezvishoma inoshandura muOrthorhombic Sulfu. Iyo yekunyungudutsa point yeOrthorhombic sarufa ndeye 112.8 ℃, iyo yekunyungudika poMoclinic Sarufa ndeye 119 ℃. Zvese zviri zviviri zvinonyanyisa muCS2.
- Kune zvakare elastic sulfu. Elastic sarufa yakasviba yero, elastic yakasimba iyo isinganyanye kuderera muCarbon kukuvadzwa kupfuura mamwe vhezheni sarufa. Izvo zvinosanganisirwa mumvura uye zvishoma zvinwiwa mudoro. Kana iyo yakanyungudutswa sarufa inokurumidza kudururwa mumvura inotonhora, iyo refu-keteni sarufa yakatarwa, yakatambanudzwa elastic sarufa. Nekudaro, zvichaomesa nekufamba kwenguva uye kuve Monclinic Sulfur.
2.chemical zvivakwa
- Sarufa inogona kupisa mumhepo, ichiita neokisijeni kuumba sarufa dioxide (saka₂) gasi.
- Sulf inoratidzira neese mahwanda pakupisa. Iyo inopisa muFluorine kuti iite sarufa hexfluoride. Mvura sarufa ine chlorine kuti iite iyo yakasimba inotsamwisa disulfur Dichloride (s2Cl2). Musanganiswa wekuenzana une iyo tsvuku sarufa dichloride (SCL) inogona kuumbwa kana chlorine iri yakawandisa uye inocheka, senge fecl3kana Sni4,inoshandiswa.
- Sulfa inogona kuita neyekupisa potassium hydroxide (Koh) mhinduro yekugadzira potassium sulfide uye potassium thiosulfate.
- Sulfu haaite nemvura uye isiri-oxidizing acids. Sulfa anowedzera neiyo inopisa nitric acid uye yakamanikidzwa sulfutic acid uye inogona kunge iri oxidized muSulfutic acid uye sarufa dioxide.
3.Application munda
- Kushandiswa kwemaindasitiri
Mashandisiro makuru eSulfu ari mukugadzirwa kweSarufa makomputa akadai seSarufa Acid, Sulfade, Sulflfude, Trichlosulfonated phosphorous, phosphorous sulf, uye solsanus sulfs, uye simbi sulfides. Anopfuura 80% yeiyo nyika yepagore sarufa inoshandiswa mukugadzirwa kweSulfutic acid. Sarufa zvakare yakashandiswa zvakanyanya mukugadzirwa kweiyo vulcanized rabha. Paunosvitsa rubber charness muvhareji, inowana elasticity yakakwirira, kupisa kupisa simba, uye kusanzwisisika mune organic sol sol. Zvigadzirwa zvakawanda zveRabha zvakagadzirwa neVulcanized Rubber, iyo inogadzirwa nekuita simbi yerabha ne uye anowedzera pane mamwe tembiricha uye dzvinyiriro. Sulfa inodiwawo mukugadzirwa kwetema dema uye mechi, uye ndeimwe yeiyo huru mbichana yemoto. Pamusoro pezvo, sarufa inogona kushandiswa mukugadzirwa kweiyo sarufuzed dyes uye pigment. Semuenzaniso, calcining musanganiswa we kaolin, kabhoni, sarufa, diatomaceous pasi, kana quartz poda inogona kuburitsa bhuruu pigment inonzi hostramarine. Iyo bleach indasitiri uye indasitiri yemishonga inodyawo chidimbu chitsidzo.
- KUSHANDISA KUSHANDISA
Sarufa ndeimwe yezvakavanzika mune akawanda eganda mishonga yeganda. Semuenzaniso, mafuta e tung anopisa nesarufa kuti afarire nesarufa acid uye akabva asina kwazvakarerekera nemvura yeAmoni kuti awane sulfonated tung mafuta. A 10% oiri yakagadzirwa kubva kune inorwisa-inti-inokanganisa uye inokanganisa mhedzisiro uye inogona kushandiswa kurapa dzakasiyana siyana ganda uye kuzvimba.
