Faction block destructions

Hello all, i came here to seek some help about a thing i dont quit understand yet and that is the faction block... i keep getting my faction block destroyed for no reason that i can understand. I had to craft it three times to just see it explode later or tomorrow..
Can someone tell me what are the different cases where the faction block will get autodestroyed and if u can also tell me more about the faction system that would be great too! (i read the rust v2 wiki more than twice but i think there are more things we should know about factions like how the power work cuz i cant get it too) Thank you!
