Description
【Technical field】
The present invention relates to lure worm type light sources technical field, specifically, be a kind of lamplight insect lure type holvi glass pipe and
Its preparation method.
【Background technology】
158,639,000 hectares of China's proportion of crop planting gross area in 2009,108,986,000 hectares of the Farming gross area, its
88,401,000 hectares of middle corn total cultivated area, 11,949,000 hectares of beans total cultivated area, the cotton planting gross area 4,952,000 is public
Hectare, 18,414,000 hectares of the growing vegetables gross area, 1,849,000 hectares of tea place area, 11,140,000 hectares of orchard area, above-mentioned plantation
Crops more or less all threatened by insect pest, and at present as a variety of causes is when threatening in the face of insect pest, most of agricultures
Family is all prevented and treated by the way of spraying insecticide.Chemical pesticide once efficiently controlled agricultural evil within a longer period
The harm of worm, is that agricultural year stable yields is made that tremendous contribution.It is however as the continuous development of chemical industry technology, rich and varied
Pesticidal products while greatly crop pest is solved the problems, such as, a series of serious problems are also produced in succession：(1) life-time service
Pesticide has produced serious side effect, makes the biotic population with resistant gene become the dominant population of insect, and Drug resistance is drastically
Rise, chemical pesticide control effect is decreased obviously even invalid.(2) sharp increase of pest resistance to insecticide level, increases making for pesticide
With dosage and frequency, ramp chemical prevention cost；(3) deteriorate agroecological environment, bring soil, water, atmospheric pollution
Etc. a series of environmental issues；(4) due to using pesticide in a large number, the pesticide for making in soil and spraying in the agricultural product for bringing is residual
Severe overweight is stayed, directly the threat mankind's is healthy, while restricting agricultural products in China enters international market, affect National Foreign Trade Balance
Easily.Chemical prevention is the hindering factor that Main Means improvement insect pest has become China's agricultural sustainable development.
How pest problem is solved in environmentally friendly manner, while realizing the green non-pollution of agricultural byproductsIn the face of crop
Insect pest, " putting prevention first and combining prevention with control " are the plant protection policies that China adheres to and implements all the time.During preventing and treating, profit
It is the Main physical measure taken at present that insect trapping is carried out with the taxis (such as the light that becomes, the taste that becomes, taxis etc.) of insecticide.Wherein,
Using insecticide phototactic characteristics, i.e., using the difference of its respective sensitive wave length of phototaxis insect, carry out using the light source of specific wavelength
Trapping, is an important physical control measure, and the important component part of integrated control.Pesticide use is reduced rationally
Number, administers the direction that insect pest is contemporary agriculture and forestry sustainable development using physical means such as light traps.
320～400nm of wavelength be the invisible long wave ultraviolet light of the mankind hundreds of insects are had it is stronger trap power, growing
In the spectral region of ripple ultraviolet light and visible ray, spectral region is wider, lures worm species more.A kind of bright lamplight insect lure type of this law
Holvi glass pipe has high permeability for the ultraviolet light of the wavelength region, can effectively kill various common crops insects,
And environment is not worked the mischief.

And chemical stability.In the present invention when BaO is less than 1%, which accelerates glass melting, and the effect for increasing glass insulation is failed to understand
It is aobvious；When BaO is more than 10%, and oxygen reacts, and clarifies melt difficult and more serious to refractory corrosion.
The present invention is the formation for promoting glassy state for the fusing for accelerating glass from the combination of MgO, reinforcing glass body
Light transmittance, expands the material temperature range of glass, the toughness of reinforcing glass body, it is easy to molding and rear processing.
The present invention can form zinc oxygen tetrahedron [ZnO from ZnO4] and enter the structural network of glass, make the structure of glass
It is more stable, while the thermal coefficient of expansion of glass can be reduced, improve the chemical stability and heat stability of glass, refractive index and
Eliminate glass strip flaw, the present invention in when ZnO be less than 0.1% when can not embody the performance impact to vitreous body, when ZnO it is big
When 5%, it is easy to produce crystal grain, light transmittance is had influence on.
The present invention selects NiO, CoO, MnO2In order to improve the uv-transmitting ability of glass, improve the material of vitreous body and add
Work performance, improves the stability of glass, extends the service life of glass lamp, while the effect with chemical decolorization.
The present invention can improve the refractive index of glass from CdO, reduce the dispersion of light, and make glass meltable.Present invention choosing
Use Nd2O3It is dispersion and the chemical stability that light is reduced for the refractive index for improving glass, extends the use longevity of glass lamp
Life.The present invention selects CeO2It is for the material founded speed, improve vitreous body for accelerating glass, while rising in melting process
To the effect of clarification, and improve the optical property of vitreous body.
The present invention selects BeO as intermediate oxide, with beryllium oxygen tetrahedron [BeO4] structural network is participated in, can be significantly
The thermal coefficient of expansion of glass is reduced, heat stability and chemical stability is improved, increases the transmitance of X-ray and ultraviolet, and energy
Improve refractive index and hardness.The performance impact to vitreous body can not be embodied when BeO is less than 0.1% in the present invention, when BeO is more than
When 3%, cost of material is greatly increased, and impact of its changes of contents to vitreous body performance diminishes.
The present invention selects P2O5It is network former, it is with phosphorus oxygen tetrahedron [PO4] formed phosphate glass structure
Network, can improve the abbe number and the ability through ultraviolet of glass, but reduce the chemical stability of glass.In the present invention when
P2O5The performance impact to vitreous body can not be embodied during less than 0.1%, works as P2O5During more than 2%, it is readily produced in vitreous body micro-
Little nanometer-size die, has influence on the transmitance of ultraviolet, and causes the reduction of vitreous body chemical stability.
