Embodiment Construction

[0019] 1. Pore protection treatment of diatomite

[0020] According to the characteristics of strong water absorption of diatomite and diatomite filter aid, diatomite and diatomite filter aid are fully mixed according to the raw material ratio shown in Table 2, so that the pores of diatomite are filled with water , so that the particles of the adhesive can be prevented from entering the pores of the diatomaceous earth, so as to achieve the purpose of protecting the pores.

[0021] 2. Bonding of diatomaceous earth particles

[0022] The diatomite and diatomite filter aid after the hole protection are mixed with organic binders (such as foam fibers), inorganic binders (such as silica-alumina sol) according to the raw material ratio shown in Table 2, in order to make the sticky The particles of the mixture are fully aggregated and cross-linked to form a network structure, and at the same time cross-linked with diatomite particles. The mixed slurry needs to be aged for 2 to 3 hou...

Abstract

The invention provides a diatomite calcinations agricultural infiltration disk which is used in conjunction with feed water piping in agricultural irrigation, wherein, 50-100 portions of diatomite, 50-100 portions of diatomite filter aid, 5-15 portions of organic bond, 5-15 portions of inorganic bond, 50-150 portions of water are taken as raw materials and then are made into porous composite material for agricultural irrigation after the process of mixing, molding, drying and calcining. The apertures in the calcined diatomite infiltration irrigation disk with a hollow structure which can be provided with one or more supporting points are between 0.1-1.0 micron and the range of the porosity thereof is 50-90 percent. The invention can perfectly solve the problems of uneven discharge flow of infiltration irrigation device and the blockage of seeping holes, thereby realizing the integrated and associated operation of irrigation and fertilization, irrigation and application as well as irrigation and bio-regulator. The invention has low technical cost, simple manufacturing technique, and long service life and can play an important role in agricultural irrigation.

Description

Technical field: [0001] The invention designs an agricultural seepage irrigation plate calcined with diatomite, and in particular relates to a porous composite material widely used in agricultural seepage irrigation fields such as greenhouses, greenhouses, urban greening, flower planting, and fruit tree planting. Background technique: [0002] my country is a large agricultural country, and the annual water shortage for agricultural irrigation is 30 billion m 3 , agricultural irrigation water accounts for more than 70% of the country's total water consumption, but the effective utilization rate of irrigation water is only 40%. The reason is that irrigation technology is backward, and flood irrigation is still the main method in most places. Seepage irrigation is a new type of water-saving irrigation technology. Seepage irrigation can also be called underground drip irrigation. When the seepage irrigation device is filled with water, the water will sweat out of the wall thro...
