Description

Magnesite wayside pavilion

Technical field

This utility model relates to a kind of outdoor use wayside pavilion, a kind of magnesite wayside pavilion.

Background technology

It is known that magnesite product is air hardening cementitious materials, its three prominent big defects are: the easy damp suction surface halide accumulation of goods, Resistance to water buckling deformation poor, easy, especially this problem of damp suction surface halide accumulation, seriously constrain sending out of product quality and industry Exhibition.Owing to the magnesium oxide/magnesium chloride mass ratio of magnesite board slip is 4～6, such system inevitably contains excess Free magnesium chloride, and free magnesium chloride is strong hygroscopic agent, it meets the wet moisture being absorbed by air, makes the surface of goods become Wet, sweat, globule trickling time serious, here it is so-called damp suction surface halide accumulation.Damp suction surface halide accumulation not only can affect the decoration effect of indoor Really, more importantly reduce the intensity of goods, shorten the service life of goods.For solving problem above, prior art is once adopted The technique that is soaked in water removes the free magnesium chloride in goods.But, this production technology not only can accelerate the early stage hydrolysis of goods, broken The mineral structure of bad goods, reduces the intensity of goods；And, sewage (containing free magnesium chloride) the most directly discharge after immersion Pollute the environment.Additionally, due to add immersion operation, increase labor intensity, make complex manufacturing, reduce and produce effect Rate.Especially at the plum rain season in the south of the River, a run of wet weather, the dry in the sun of goods is little to realize.
