The manufacturing technique method producing relatively thin glass mainly has float process process, overflow downdraw manufacturing technique method.
The topmost feature of float glass process is the increase in a molten tin bath, after melted vitreous humour flows into molten tin bath,
Owing to gravity and the capillary effect of vitreous humour are shakeout naturally, then through pull, anneal, cooling down curable type, to become upper and lower surface flat
Whole smooth plate glass, molten tin bath is the core of floating process, but the increase of molten tin bath also brings some problem, stannum in molten tin bath
Liquid, the vitreous humour of molten state and protective gas constitute heterogeneous, a uncontrollable complication system at high operating temperatures, special
It not during the precise controlling producing thin glass, in order to overcome vitreous humour gravity and capillary effect, need to increase
Edge machine quantity, traction machine is set, and accurately controls edge machine and the technological parameter of traction machine, additionally, glass plate molten tin bath this
In uncontrollable multiphase system of individual closing, the time of staying is longer, and the chemical reaction process in molten tin bath is extremely complex, and is difficult to
Detect and control its concrete chemical reaction process, so, the uncontrollable factor in molten tin bath makes glass light distortion point, fiber crops easily occur
The defects such as point, cloud point, iris, tin sticky, wavy bending, scuffing, also have certain limitation on the thickness producing glass, and
And float process technological equipment investment is high, infrastructure project is bigger；
Overflow downdraw production technology is the mode using " from top to bottom ", by the vitreous humour clarified through homogenizing through platinum
Passage flows into after overflow launder, and vitreous humour, merges in tapered lower portion along two trough rims along conical section to underflow stream,
Utilizing guide roll to draw downwards and pull formation glass tape, its production technology also exists melting furnaces system to be needed to choose height, build in away from one-tenth
The eminence of type end, the problem that capital construction construction project is more difficult.
