Abstract
The invention discloses an additive capable of prolonging the service life of chemically strengthened fused salt, which comprises the following major constituents: several kinds of carbonates, bicarbonates, nitrates, nitrites and other active constituents, wherein the ratio of carbonates to bicarbonates to nitrates to nitrites to others is 5:2-5:60-63:25:5. The invention has the characteristics of low cost, rapid effect taking and the like. The additive can effectively prolong the service life of fused salt, increase the yield of fused salt per unit and play the function of reducing production cost.
Description
Technical field
The present invention relates to a kind of additive, particularly relate to and a kind ofly can prolong the chemical tempering fused salt additive in work-ing life.
Background technology
In the eyeglass processing industry,, require that eyeglass is carried out chemical tempering and satisfy service requirements to reach certain intensity for surface hardness and the shock resistance that improves product.But along with widespread use to glass mirror, portioned product is had higher requirement to the chemical enhanced performance index of glass mirror, that have even require eyeglass (just can satisfy service requirements fully) need reaching through its surface stress behind the chemical tempering more than the 800MPa as long as common product reaches 400MPa, this need adopt the quite high fused salt of purity to carry out tempering with regard to requiring us, but the employed fused salt of chemical tempering itself is a kind of running stores, increase along with tempering product amount, the purity of its fused salt also can decrease, after the fused salt purity drop arrives to a certain degree, then must change whole fused salts and just can reach corresponding tempering performance index.In other words, as if the chemical tempering performance index of wanting to reach higher, then must take frequent replacing fused salt to reach, this is unfavorable for the production in enormous quantities of product fully.
Summary of the invention
It is low that technical problem to be solved by this invention provides a kind of cost, instant effect can prolong the chemical tempering fused salt additive in work-ing life.
In order to solve the problems of the technologies described above, provided by the inventionly can prolong the chemical tempering fused salt additive in work-ing life, it is characterized in that: the weight proportion of each component is:
Carbonate: acid carbonate: nitrate: nitrite: other=5: 2～5: 60～63: 25: 5.
By the ratio that the present invention sets, has the prolongation in work-ing life of good chemical tempering fused salt.
Carbonate and acid carbonate are technical grade or above purity grade product.
Nitrate and nitrite are industrial first grade or above purity grade product.
Other components are analytical pure or above purity grade product.
That adopts technique scheme can prolong the chemical tempering fused salt additive in work-ing life, according to the requirement of the different chemical tempering performance index of product, carbonate, acid carbonate, nitrate, nitrite and some other material thereof are obtained additive of the present invention by certain ratio requirement mixing.And reach by the proportioning between each component in this change additive and to prolong the chemical tempering fused salt purpose in work-ing life.
The present invention shows as by its outstanding effect of the advantage that effective proportioning had of above composition: under same chemical tempering performance requriements, can improve more than 100% the work-ing life of fused salt, even longer.The additive that can prolong chemical tempering fused salt work-ing life can directly be added in the fused salt, simple and quick, need not the operation of complicated specialty, can reach the required chemical tempering fused salt prolongation effect in work-ing life in 2 hours as long as after the complete fusion of additive, leave standstill.
The present invention is applied to the chemical tempering processes of glass mirror, utilizes the two-phase coexistent relation of various ingredients, has reached raising ion-exchange activity, prolongs chemical tempering fused salt work-ing life, improves unit fused salt production capacity and reduces production costs.

Embodiment
By the detailed description of carrying out below in conjunction with accompanying drawing, particular exemplary of the present invention and the characteristics in case study on implementation, advantage and others will become apparent.
Provide following description to help the of the present invention exemplary case study on implementation that complete understanding is limited by claim and equivalent thereof with reference to accompanying drawing.Below describe and comprise various specific details helping described understanding, but these details should be understood that to be exemplary.Therefore, it will be understood by those skilled in the art that under situation about not departing from the scope of the present invention with spirit, can carry out various changes and modification case study on implementation described here.In addition, for clarity and conciseness for the purpose of, omit description to known function and structure.
With reference to Fig. 1, this figure is a theoretical basis of the present invention, normal, glass its surface stress size behind chemical tempering can reduce along with the reduction of fused salt concentration, can prolong fused salt work-ing life by the mode of taking to add additive, and additive can carry out the adjustment of different ratios according to proportioning of the present invention, to reach the maximum extension fused salt effect in work-ing life.
What select for use in the concrete embodiment of the present invention is a kind ofly can prolong the chemical tempering fused salt additive in work-ing life, wherein carbonate and acid carbonate are technical grade or above purity grade product, nitrate and nitrite are industrial first grade or above purity grade product, and other components are analytical pure or above purity grade product.
In following case study on implementation, be statement and the explanation that embodiment does correlated performance of the present invention only with carbonate and acid carbonate.
