Nta:
Boron nyob rau hauv ib qho chaw tshwj xeeb nyob nruab nrab ntawm cov hlau thiab cov uas tsis yog hlau ntawm lub rooj periodic ntawm cov ntsiab lus. Nws cov khoom siv tshuaj lom neeg muaj zog dua vim muaj hluav taws xob tsis zoo heev, lub voj voog me me thiab lub zog nuclear centralized. Nws ruaj khov hauv qhov kub ib txwm, oxidized thaum cua sov txog 300 ℃, thiab hlawv yog cua sov txog 700 ℃. Nws tsis muaj saj thiab tsis muaj ntxhiab. Nws cov khoom tsis yog hlau zoo ib yam li silicon. Boron tuaj yeem cuam tshuam nrog oxygen, nitrogen, sulfur, halogen lossis carbon thiab lwm yam. Nws tuaj yeem sib xyaw ncaj qha nrog ntau hom hlau los tsim cov tshuaj boronic. Ntxiv mus, boron kuj tseem tuaj yeem cuam tshuam nrog cov tshuaj organic los tsim qee cov tshuaj, uas boron koom nrog carbon ncaj qha, lossis oxygen muaj nyob nruab nrab ntawm boron thiab carbon.
Cov ntawv thov:
Boron feem ntau yog siv rau hauv metallurgy, electronics, tshuaj, ceramics, nuclear kev lag luam thiab tshuaj lom neeg thiab lwm yam, nws yog siv rau hauv daim ntawv ntawm cov tshuaj sib xyaw lossis ntxiv rau hauv qee cov alloys ua ib qho ntxiv. Nws tuaj yeem siv rau hauv kev smelting ntawm qee cov hlau alloy tshwj xeeb thiab ua cov roj tshem tawm rau cov hlau yaj, hauv lub qhov cub hlawv-entraining ntawm lub raj hlawv-entraining hauv kev lag luam, hauv tus pas tswj ntawm atomic reactor, thiab hauv cov roj muaj zog siab rau rocket. Nws yog ib qho khoom siv tseem ceeb rau kev ua cov halogenated borons ntshiab, kuj yog ib qho khoom siv rau kev ua ntau yam boronic sib xyaw. Ntau yam hlau zoo thiab tsis tshua muaj tuaj yeem hloov thiab txuag los ntawm nws. Boron thiab nws cov sib xyaw kuj tuaj yeem siv ua cov catalyst rau qee cov tshuaj lom neeg organic, thiab lwm yam.
Pob:
Nws tau ntim rau hauv lub hnab yas uas muaj lub tshuab nqus tsev.
Qhov hnyav tag nrho 1kg ib lub hnab, 5kg / thawv, 10kg / thawv, 25kg / thawv
Cia Khoom:
Yuav tsum khaws cia rau hauv qhov chaw ntxoov ntxoo, cua nkag tau zoo, thiab qhuav. Lub txee khaws cia tau ib xyoos.
Cov khoom tseem siv tau yog tias ua tau raws li tus qauv los ntawm kev rov sim dua tom qab hnub teev tseg.
Cov ntawv ceeb toom kev nyab xeeb:
Cov khoom no suav tias yog lom los ntawm kev nqus pa thiab noj, kev nqus pa nws yuav muaj kev cuam tshuam rau lub paj hlwb hauv nruab nrab, kev noj nws yuav ua rau lub plab thiab txoj hnyuv ua haujlwm thiab lom boron, kev sib cuag nrog daim tawv nqaij lossis qhov muag yuav ua rau muaj kev cuam tshuam me ntsis, yuav tsum hnav tsom iav tiv thaiv kev nyab xeeb, lub ntsej muag tiv thaiv plua plav, hnab looj tes roj hmab thaum tuav nws.
