Description
Technical field
The invention belongs to glass fining agent technical field, specifically the compound clarifier in a kind of touch screen cover-plate glass production technology.
Background technology
The bubble that glass melt internal contamination thing is formed is referred to as " seed ".The existence of seed has impact for the refractive index of glass, density and light transmittance.The process that figure's field trash removes from melt is called the clarification of glass or refining.The chemical constituent introduced in glass for reaching clarifying effect is referred to as clarifier.Traditional clarifier mostly is oxide or the acid of arsenic, and content generally accounts for the 0.9-1.1%(percentage by weight of glass).Arsenic has good clarifying effect, yet with the toxicity of arsenic, brings very big financial burden for producing and processing.Antimony is the succedaneum of the arsenic of follow-up appearance, although can reach necessarily clarification purpose and toxicity and reduce to some extent, but still be harmful to, and expensive be unfavorable for environmental protection.Furthermore, for touch screen cover-plate glass, clarifier add it should also be taken into account that the instructions for use of its light weight, high intensity.
Summary of the invention
The present invention is to solve above-mentioned technical problem, devise the compound clarifier in a kind of touch screen cover-plate glass production technology, this compound clarifier is outside the requirement taking into account clarifying effect, it is ensured that touch screen cover-plate glass light weight, be prone to the advantages such as chemical tempering.
The technical solution used in the present invention is: the compound clarifier in a kind of touch screen cover-plate glass production technology, for eliminating the bubble in melten glass liquid, it is critical only that: with NaCl for major ingredient in described clarifier recipe ingredient, be aided with SnO and K2SO4, wherein, the weight percent content of above component is:
NaCl74 ~ 93%,
SnO2 ~ 8%,
K2SO45~18%。
The invention has the beneficial effects as follows: 1, adopt oxidation clarification, sulfur clarification to clarify, with halogen, the composite clarification mode combined, give full play to cooperative effect and the Overlay of three, the effect continuing to clarify can be reached, greatly enhance clarifying ability；2, halogen ion, gasification volatilization can be discharged in the clarification stage of touch screen cover-plate glass manufacturing process as the NaCl of clarification main body, promote vitreous humour clarification；3, this clarifier introduces a certain amount of SnO to assist for the purpose of clarification, and for while coordinating clarification and ensure the cost of light weight and relative moderate, the addition of SnO is designed as 2%～8%；4, by assist clarification for the purpose of introduce a certain amount of K2SO4, appropriate K+Helpful for later stage tempering, for avoiding refractory brick is caused erosion, K while ensureing clarification and later stage tempering effect2SO4Addition be designed as 5%～18%；5、Na+With K+Introducing not only can meet the demand of fluxing, more can to improve touch screen cover-plate glass tempering effect offer help；6, introduce this compound clarifier and can make touch screen cover-plate glass density relative reduction, it is thus achieved that lightweight advantage, be suitable to market large scale demand.
Detailed description of the invention
