Abstract
The invention discloses a ventilating duct with a high transmission rate. The ventilating duct comprises a wind guide tube and a compression resisting layer fixedly mounted on the outer surface of the wind guide tube. The wind guide tube is formed by mixing of glass fibers and cement, and comprises, by mass, 36-42% of the glass fibers and 58-64% of the cement. The compression resisting layer is formed by high-temperature fusion of epoxy resin and phenolic resin, and comprises, by mass, 45-52% of the epoxy resin and 48-55% of the phenolic resin. The ventilating duct has the advantages that compression resistance of the ventilating duct can be improved, adsorption performance of the ventilating duct can be weakened, resistance-free transmission of wind power is achieved, and the transmission rate of wind volume is increased.
Description
Technical field
The present invention relates to a kind of ventilation equipment, particularly a kind of ventilation duct of high transmission ratio.
Background technique
Along with the development of science and technology, all trades and professions constantly emerge, the scale of current each enterprise is increasing, and at on-site, all need between main equipment to adopt ventilation duct to carry out connection conveying, and current ventilation duct adopts concrete manufacture mostly, the load that this traditional ventilation duct bears is limited, and the absorptivity possessed due to concrete material itself, cause the transmission ratio of ventilation duct lower.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of ventilation duct of high transmission ratio, can not only improve the compression resistance of ventilation duct, can also reduce the adsorption performance of ventilation duct, makes wind-force can non-resistance transmission, improves the high transmission ratio of air quantity.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: the ventilation duct providing a kind of high transmission ratio, comprise: guide duct and the resistance to compression layer being fixedly mounted on described guide duct outer surface, described guide duct is formed by glass fibre and cement mixing, proportioning is carried out: the content of described glass fibre accounts for 36-42% according to mass fraction, the content of described cement accounts for 58-64%, described resistance to compression layer is formed by epoxy resin and the fusion of phenolic resin high temperature, proportioning is carried out: the content of described epoxy resin is 45-52% according to mass fraction, the content of described phenolic resin is 48-55%.
In a preferred embodiment of the present invention, the thickness of described resistance to compression layer is 5-8mm.
In a preferred embodiment of the present invention, the thickness of described guide duct is 8-10mm.
In a preferred embodiment of the present invention, the temperature that described high temperature merges is 1000 DEG C.
The invention has the beneficial effects as follows: the present invention can not only improve the compression resistance of ventilation duct, the adsorption performance of ventilation duct can also be reduced, make wind-force can non-resistance transmission, improve the high transmission ratio of air quantity.
Embodiment
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
