Features:
Boron iri panzvimbo yakakosha pakati pesimbi uye isiri-metal pane periodic tafura yezvinhu. Zvimiro zvayo zvemakemikari zvinonyanya kushanda nekuda kwemagetsi asina kunaka akasimba, diki diki yeatomu uye chepakati chenyukireya. Yakatsiga mutembiricha yakajairika, inoiswa oxidized kana ichidziya kusvika 300 ℃, uye inopiswa kana ichipisa kusvika 700 ℃. Haina kunaka uye haina hwema. Iyo isiri-metal pfuma yakafanana nesilicon. Boron inogona kudyidzana neokisijeni, nitrogen, sarufa, halogen kana kabhoni nezvimwewo. Inogona kusanganiswa yakananga nemhando dzakawanda dzesimbi kuita boronic compounds. Uyezve boron inogonawo kubatwa nemakomboni organic kugadzira mamwe makomisheni, umo boron inobatanidzwa zvakananga kune kabhoni, kana okisijeni iripo pakati peboron nekabhoni.
Applications :
Boron inonyanya kushandiswa musimbi, zvemagetsi, mushonga, ceramics, nulear indasitiri uye makemikari indasitiri nezvimwe, inoshandiswa muchimiro chemukomboni kana inowedzerwa mune mamwe alloys sekuwedzera. Inogona kushandiswa mukunyungudutsa mamwe masimbi akakosha alloy uye sechibvisi chegasi chesimbi inonyunguduka, mumoto unopisa-inopinza danda rekupisa-entraining chubhu muindasitiri, mutsvimbo yekudzora yeatomu reactor, uye mune yakakwirira-simba. mafuta e rocket. Icho chinhu chakakosha chekugadzira high-pure halogenatedborons, uyewo zvinhu zvekugadzira zvakasiyana-siyana zveboronic compounds. Mazhinji masimbi ane mbiri uye asingawanzo anogona kutsiviwa uye kuponeswa nawo. Boron nemakomponi ayo anogona kushandiswa zvakare sechikonzero cheimwe organic kemikari maitiro, zvichingodaro.
Pakeji:
Iyo vacuum-yakazara mumabhegi ealuminium foil, umo akaiswa bhegi repurasitiki.
Net uremu 1kg bhegi, 5kg/katoni, 10kg/katoni, 25kg/katoni
Kuchengeta:
Inofanira kuchengetwa munzvimbo ine mumvuri, inofefetera uye yakaoma. Hupenyu hwesherufu hwayo igore rimwe.
Chigadzirwa chinogona kuramba chichishandiswa kana chasvika pachiyero kuburikidza nekuongororazve mushure mezuva rakatarwa.
Safety notes:
chigadzirwa chinoonekwa sechepfu nekufema uye kudya, kufemesa kuchava nemhedzisiro pane yepakati tsinga system, kuidya kunotungamira mukukurudzira mudumbu uye matumbo canal uye boron poisoning, kusangana neganda kana maziso kuchaita kuti kuwedzere kudiki. , inofanira kupfeka magirazi ekudzivirira ekudzivirira, guruva rinodzivirira gauze mask, magurovhosi erubha panguva yekuibata.
