Abstract
The invention provides a process for preparing a solar glass tube. The solar glass tube prepared by the process is high in transparency and light in weight; through the addition of aluminum oxide and magnesium oxide, the mechanical strength of the solar glass tube can be improved, and boric acid and calcium oxide are capable of enhancing the mechanical property of the solar glass tube; meanwhile, the process method is simple, and is suitable for the mass production of the glass tube.
Description
Technical field
The present invention relates to a kind of Glass tubing, particularly relate to a kind of solar energy glass pipe preparation technology.
Background technology
Solar energy glass pipe itself is a kind of product innovation, and its production and utilisation technology are all among constantly exploring and improving.In recent years, the engineering design of China's solar energy glass pipe, coordinative composition of equipments and production technology are day by day ripe, and the domestic newly-built production line majority founding a capital achieves production domesticization.The large-scale kiln design and construction of one kiln two line, kiln four line and production technology have also withstood the inspection of practice.Present domestic solar energy glass pipe enterprise is all not less than overseas enterprise in yield rate and product all technical.
Summary of the invention
The invention provides a kind of solar energy glass pipe preparation technology.For realizing object of the present invention, technical scheme of the present invention is as follows:
A kind of solar energy glass pipe preparation technology, it is characterized in that, described step of preparation process is:
(1) silicon-dioxide, boric acid, boric acid, aluminum oxide, salt are put into glass mortar and carefully ground, then to load in corundum crucible in the High Temperature Furnaces Heating Apparatus taking Si-Mo rod as Heating element 1200-1550 DEG C of insulation 2-4 hour, form high temp glass solution;
(2) after, high temp glass solution is poured over quenching in aluminium-making mould heated in advance and becomes Glass tubing, then put into resistance furnace in 400-550 DEG C of annealing 2-3 hour;
Preferably, silicon-dioxide in described step (1), boric acid, the mass ratio of boric acid, aluminum oxide, salt is 3:1:0.5:0.2:0.01.
Preferably, in described step (2), aluminium-making mould is heated to 90-120 DEG C in advance.
Beneficial effect: the invention provides a kind of solar energy glass pipe preparation technology, its solar energy glass pipe transparency prepared is high, lightweight, aluminum oxide and magnesianly add the physical strength that can improve solar energy glass pipe, boric acid and calcium oxide can increase its mechanical property, this processing method is simple and easy simultaneously, is easy to the scale operation of Glass tubing.
