Abstract
The invention provides a process for preparing a solar glass tube. The outstanding performance of selected methyl methacrylate is that the transparency is high, and the light transmittance can reach 90 to 95 percent; moreover, the relative density is low, and the weight is light. The solar glass tube prepared by the process is high in impact strength and has good performance under high temperature.
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) pre-polymerization: 10-12g methyl methacrylate, 0.2-0.5g dibenzoyl peroxide, 3-5ml dibutyl phthalate are joined in reactor, shake up rear water-bath, be progressively heated to 75-86 DEG C, insulation 20-40min, after stopping heating, be cooled to 40-45 DEG C rapidly;
(2) build and be polymerized: by material implantation glass pipe mold good for pre-polymerization, and adding stablizer, afterwards mould is put into the baking oven of 50-55 DEG C, polymerization 12-14h, heightens temperature and is polymerized 2-3h further to 110-120 DEG C;
(3) demoulding: take out mould, open mould clean-out system and clean Glass tubing, put into 45-55 DEG C of baking oven 20-30min and carry out drying and processing, obtain Glass tubing finished product.
Preferably, in described step (2), Na selected by stablizer
2o, its add-on is 0.1-0.2g.
Preferably, in described step (3), the ethanol of 0.1-0.2mol/L selected by clean-out system.
Beneficial effect: the invention provides a kind of solar energy glass pipe preparation technology, its most outstanding performance of the methyl methacrylate selected be there is high-clarity, transmittance can reach 90-95%, and relative density is little, quality is light.The solar energy glass pipe impact strength that this technique is prepared is high, excellent property under high temperature.
Embodiment
A kind of solar energy glass pipe preparation technology, it is characterized in that, described step of preparation process is:
(1) pre-polymerization: 10g methyl methacrylate, 0.5g dibenzoyl peroxide, 5ml dibutyl phthalate are joined in reactor, shakes up rear water-bath, be progressively heated to 86 DEG C, insulation 40min, after stopping heating, is cooled to rapidly 45 DEG C;
(2) build and be polymerized: by material implantation glass pipe mold good for pre-polymerization, and adding stablizer, afterwards mould is put into the baking oven of 55 DEG C, polymerization 14h, heightens temperature to 120 DEG C further polyase 13 h;
(3) demoulding: take out mould, open mould clean-out system and clean Glass tubing, put into 55 DEG C of baking oven 30min and carry out drying and processing, obtain Glass tubing finished product.
Wherein, in described step (2), Na selected by stablizer
2o, its add-on is 0.2g, and in described step (3), the ethanol of 0.2mol/L selected by clean-out system.
The invention provides a kind of solar energy glass pipe preparation technology, its most outstanding performance of the methyl methacrylate selected be there is high-clarity, transmittance can reach 90-95%, and relative density is little, quality is light.The solar energy glass pipe impact strength that this technique is prepared is high, excellent property under high temperature.
As known by the technical knowledge, the present invention can be realized by other the embodiment not departing from its spirit or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Within the scope of the present invention all or be all included in the invention being equal to the change in scope of the present invention.
