Description
[technical field]
The present invention relates to artificial crystal production field more particularly to a kind of manufactures of rare earth tinted clear grey crystal bead blank
Method.
[background technique]
The technique of conventionally manufactured opaque grey crystal bead blank, using coal gas or with natural gas to crucible stove heating, due to coal
Gas or with the atmosphere in the bad control crucible furnace of heated by natural gas, it is unstable to will lead to glass colour, influences product quality.Also have
Melting carried out to glass using continuous battery furnace, this continuous battery furnace generally can only continuous production single variety glass system
Product, colour changing is extremely inconvenient, and the raw material for forcing colour changing to will lead to preceding color pearl embryo remains in the color pearl embryo produced next time
In, cause pearl embryo size color difference serious, there is bubble striped in inside, and transmissivity and refractive index be not high, unstable product quality.It needs
Produce high-grade color stablize, the estriate high-grade opaque grey crystal bead blank of bubble-free, it is necessary first to match in pearl embryo raw material
Outside the research and development put into greatly in side and proportion, it is also necessary to adjust in production technology, be changed with adapting to production specification size
Expect flexible, small lot, high-quality opaque grey crystal pearl base.
[summary of the invention]
Present invention seek to address that traditional pearl embryo color difference is serious, there is bubble striped in inside, and transmissivity and refractive index be not high, product
The problem of unstable quality and a kind of manufacturing method of rare earth tinted clear grey crystal bead blank is provided, pearl embryo matches in this method
It can guarantee that pearl embryo has high refractive index and high refractive index, electric heating covered pot furnace atmosphere is stablized, and will not make to produce inside pearl embryo
Anger bubble striped, internal clarification, stable structure, product are higher by multiple shelves compared to the pearl embryo that conventional formulation and production method are produced
It is secondary.
To achieve the above object, the manufacturing method of rare earth tinted clear grey crystal bead blank of the invention, rare earth coloring
The weight proportion of opaque grey crystal bead blank raw material are as follows: 40~60 parts of iron-content 5PPM quartz sand below, sodium carbonate 6~17
Part, 0.5-4 parts of potassium carbonate, nitric acid receive 0.5~4 part, 5-10 parts of borax decahydrate, 8-13 parts of zinc oxide, aluminium oxide≤5 part, Fang Xie
Stone≤6 part, 0.5-3 parts of titanium dioxide, barium carbonate≤2 part, 0.3-1 parts of prodan, lithium carbonate≤4 part, erbium oxide≤1.5 part,
Cobalt oxide≤0.2 part, nickel oxide≤0.5 part, antimony oxide≤1 part.
Further, the manufacturing method of rare earth tinted clear grey crystal bead blank includes the following steps:
S1: it is uniformly mixed after the raw material of rare earth tinted clear grey crystal bead blank is weighed up by weight ratio；
S2: uniformly mixed mixture is added in the electric heating covered pot furnace furnace that temperature is 1300-1400 degrees Celsius
Dissolution 10 hours or more；
S3: it by the cooling heat preservation of the glass solution of dissolution to 1100 degrees Celsius, is sent by choosing material mode to tamping plant, compacting
Opaque grey crystal bead blank out；
S4: opaque grey crystal bead blank fine-grinding and polishing is formed.
Further, powder of the raw material of opaque grey crystal bead blank between 20-200 mesh in step S1, is stirred
Time is not less than 40 minutes.
Further, the time that mixture dissolves in electric heating covered pot furnace in step S2 is 10-15 hours.
Further, mixture is put into several times in electric heating covered pot furnace, guarantees to have put into feed intake next time before mixed
Closing material has been in dissolved state.
Contribution of the invention is the provision of a kind of manufacturing method of rare earth tinted clear grey crystal bead blank.With rare earth oxygen
The glass of compound coloring becomes rare earth coloured glass, and rare earth coloured glass color is gorgeous, coloring stabilized, under normal circumstances not by oxygen
Change the influence of reducing atmosphere, this is because optical source wavelength of the glass at place is different, glass is also just different to its light absorption, not
Different colours are shown under irradiating with light source.When being used in mixed way with rare-earth colorant and other colorants, glass generation can be made to be permitted
The color of more different-effects.Because rare-earth colorant has unique soft and graceful intermediate color and higher refractive index,
This for improve crystal bead blank class, the upgrading of product, into competition in the international market have certain meaning.The present invention
In using quartz sand, calcite, sodium carbonate, potassium carbonate as soda-lime glass main component；Using cobalt oxide (blue), oxidation
Nickel (grey), erbium oxide (pink) proportionally mix coloring grey；Utilize sodium carbonate, potassium carbonate, lithium carbonate, prodan
It realizes and accelerates glass biodissolution, while improving product quality, the addition of borax decahydrate keeps fluxing effect more obvious；Sodium nitrate exists
Oxidizing atmosphere is adjusted when glass melting；Antimony oxide plays the role of clarification, de-soak；Zinc oxide, barium carbonate, is used for titanium dioxide
Refractive index is improved, aluminium oxide improves the effect of strength of glass, stablizes product structure.In addition in production method of the invention,
Melting is carried out to glass using electric heating covered pot furnace, replacement color is convenient, and product not will form color difference, will not inside pearl embryo
There is bubble striped.
