B4C nanopwder Pùdar carbide boron airson stuth tàthaidh
Tuairisgeul toraidh
Micropowder Black B4C Boron Carbide Pùdar airson còmhdach ceirmeach
Is e boron carbide, alias daoimean dubh, pùdar dathte.Is e aon de na trì stuthan as cruaidhe a tha aithnichte (is e daoimean agus boron nitride ciùbach an dà fhear eile) agus tha e air a chleachdadh ann an armachd tanca, deiseachan dìon-urchair agus mòran thagraidhean gnìomhachais.Tha e air a chleachdadh ann an stuthan caitheamh-dhìonach, ìre ath-neartachadh ceirmeag, gu sònraichte ann an armachd aotrom, reactair neodron absorbent, etc.
