Description
Technical field
The present invention relates to counter balance fields, it is more particularly related to a kind of student chemical experiment pallet day
It is flat.
Background technique
Chemical balance is a kind of precision mass metrical instrument used in chemical experiment research, and being that chemical laboratory is common claims
One of measuring appratus.It is typically used as stoichiometric chemistry drug quality.Traditional chemical balance is made of the gentle counterweight in day: balance is basis
The measurement instrument of lever principle production；Counterweight is the standard of quality.Quality and weight is being physically two different concepts,
But history and it is customary due to, quality and weight all uses same unit, and the use generation both made is obscured.Chemistry
Upper accustomed to using " weight " this noun, but precisely, day aequum the result is that the mass value of object.
The balance edge of a knife is an important structure in support holder structure, and edge of a knife position is sharper, and the sensitivity of balance is higher, essence
It spends also higher.Inherently edge of a knife position is improved while promoting balance sensitivity, but makes the edge of a knife more cutting edge of a knife or a sword
While sharp, thickness will be thinner.
Chemical balance needs constantly to add reagent in use or raw material weighs to it, therefore tray rack meeting
It constantly swings in the whole process, is finally reached balance, in this process edge of a knife position can be caused to wear, caused
Edge of a knife position is damaged, but is completely fixed tray rack and is not met the use demand of chemical balance.
