Mawonekedwe:
Boron ali pa malo apadera pakati pa zitsulo ndi zopanda zitsulo pa tebulo la periodic la zinthu. Mankhwala ake amakhala otanganidwa kwambiri chifukwa cha magetsi amphamvu kwambiri, ma radius ang'onoang'ono a atomiki ndi nyukiliya yapakati. Ndiwokhazikika pa kutentha kwabwinobwino, okosijeni ikatenthedwa kufika ku 300 ℃, ndipo imawotchedwa ngati yatenthedwa kufika ku 700 ℃. Siimva kukoma ndi fungo. Katundu wake wopanda chitsulo ndi wofanana ndi silicon. Boron ikhoza kuyanjana ndi mpweya, nayitrogeni, sulfure, halogen kapena carbon etc. Ikhoza kuphatikizidwa mwachindunji ndi mitundu yambiri yazitsulo kupanga mankhwala a boronic. Komanso boron imathanso kukhudzidwa ndi zinthu zachilengedwe kuti apange zinthu zina, momwe boron imalumikizidwa mwachindunji ndi kaboni, kapena mpweya umakhala pakati pa boron ndi kaboni.
Mapulogalamu :
Boron amagwiritsidwa ntchito makamaka muzitsulo, zamagetsi, mankhwala, zoumba, mafakitale a nulear ndi mafakitale a mankhwala etc, amagwiritsidwa ntchito ngati mawonekedwe a pawiri kapena amawonjezeredwa muzitsulo zina monga chowonjezera. Itha kugwiritsidwa ntchito posungunula zitsulo zina zapadera za aloyi komanso ngati chochotsera gasi chitsulo chosungunuka, mumtengo woyaka-entraining wa chubu choyaka moto m'makampani, mu ndodo yowongolera ya riyakitala ya atomiki, ndi mphamvu yayikulu. mafuta a rocket. Ndizofunikira kwambiri popanga ma halogenatedborons apamwamba kwambiri, komanso zinthu zopangira mitundu yosiyanasiyana ya boronic. Zitsulo zambiri zolemekezeka komanso zosawerengeka zimatha kusinthidwa ndikupulumutsidwa nazo. Boron ndi mankhwala ake atha kugwiritsidwanso ntchito ngati chothandizira pazachilengedwe, ndi zina zotero.
Phukusi:
Zitsulo zake zodzaza ndi matumba a aluminiyamu zojambulazo, zomwe zayikidwamo thumba la pulasitiki.
Net kulemera 1kg thumba, 5kg/katoni, 10kg/katoni, 25kg/katoni
Kusungirako:
Iyenera kusungidwa m'nyumba yosungiramo mthunzi, mpweya wabwino komanso youma. Alumali moyo wake ndi chaka chimodzi.
Zogulitsa zitha kugwiritsidwabe ntchito ngati zili mulingo poyesedwanso pambuyo pa tsiku lodziwika.
Zolemba zachitetezo:
mankhwala amaonedwa kuti ndi poizoni pokoka ndi kudya, pokoka mpweya adzakhala ndi zotsatira pa chapakati mantha dongosolo, kudya izo zidzachititsa kukondoweza m'mimba ndi matumbo ngalande ndi boron poizoni, kukhudzana ndi khungu kapena maso adzatsogolera kukondoweza pang'ono. , ayenera kuvala magalasi oteteza chitetezo, chigoba chopanda fumbi, magolovesi amphira pochigwira.
