Description
Technical field
The present invention relates to glass composition, especially a kind of crystal glass material, its feedstock composition and its manufacturing method.
Background technique
Crystal glass refers to very high transparency and biggish refractive index, bright and clean sparkling and crystal-clear, such as mineral crystal, also known as crystal
Glass.Crystal glass has broad sense and narrow sense two types, and the crystal glass of broad sense includes: lead crystal glass, barium crystal glass, zinc
Crystal glass, titanium crystal glass and zirconium crystal glass and mixed type crystal glass, narrow sense only refer to lead crystal glass.
One of key factor is exactly the bubble contained in glass in terms of glass quality, and glass is by by silica sand, soda ash, stone
After the raw materials such as lime stone mix, being melted at high temperature, the glass after high temperature melting is a kind of highly viscous liquid,
In include a large amount of bubble, when not using any clarifying agent, carbon dioxide, the content of nitrogen are most in bubble, and they
Cannot melt again with melten glass liquid, if it is single rise to metal level by bubble after rupture release, that will need to consume big
The time of amount is unacceptable to industrialized production.The bubble that glass melting generates usually is eliminated by two ways,
The skin breakage of glass metal is risen to one is bubble and is discharged, and another kind is that bubble is dissolved in melten glass liquid.It is melting
The gas that can be melted in glass metal mainly has sulfur dioxide, oxygen, hydrogen etc., and the gas that cannot be melted mainly has nitrogen, two
Carbonoxide and some other inert gas.In the past, in order to reduce the bubble in glass, using arsenic and nitrate cooperate as
A kind of clarifying agent is introduced into glass batch, but arsenic can partially volatilize cause environmental pollution at high temperature, and arsenic is made
For a kind of extremely toxic substance, it is difficult to be managed, therefore, the continuous improvement with people to environmental requirement, more and more countries
It has begun and recognizes the harm of arsenic in glass, the developed countries such as Europe and Japan strictly forbid using in glass
Arsenic.In recent years, in glass production frequently with sodium nitrate, fluoride and arsenic oxide arsenoxide as clarifying agent.Since sodium nitrate is in glass
Toxic gas nitrogen dioxide (the NO of brownish red sharp aroma is decomposed to give off in glass fusion process2).Nitrogen dioxide (NO2) by human body
Respiratory tract can be damaged after sucking.Nitrogen dioxide (NO2) to be discharged into brought environmental effect in atmosphere varied, comprising: to wet
The influence with composition variation, the reduction of atmospheric visibility, the acidification of surface water, eutrophy are competed between ground and terrestrial plant species
Change and (lead to anoxic due to being rich in the nutrients algal bloom such as nitrogen, phosphorus in water) and increase be harmful in water body fish and
The content of toxins of other aquatiles.And fluoride category high poison substance, human body is entered by respiratory tract, mucous membrane can be caused to pierce
The symptoms such as sharp, poisoning, and the normal physiological function of each tissue and organ can be influenced, danger can also be generated to growth, the development of plant
Evil.And arsenic oxide arsenoxide belongs to inorganic toxic articles.Human body sucking, main influence nervous system and capillary permeability after eating, it is right
Skin and the irritating effect of mucous membrane.Therefore, above-mentioned clarifying agent has toxic action to environment and human body.
