Problems solved by technology

However, the ceramsite used in horticulture in our country is basically made by sintering method, and the internal structure of ceramsite products is solid.
In particular, the solid ceramsite has a low water absorption rate and low nutrient storage capacity. This is due to the small internal voids of the ceramsite resulting in a small specific surface area of ​​the ceramsite, resulting in poor water storage capacity and nutrient storage capacity of the ceramsite. Ceramsite cannot guarantee the water and nutrients needed by plants for a long time; in addition, the high bulk density of solid ceramsite also brings more inconvenience to horticultural cultivation, especially the low air permeability of high-density ceramsite is also Affects the growth of horticultural plants to a certain extent

Embodiment 1

[0015] Embodiment 1 The preparation method of horticultural hollow unfired ceramsite includes the following steps: (1) Preparation of ceramsite core 6: mix and extrude according to the weight ratio of 80kg of sawdust, 15kg of sawdust decay treatment agent, 4kg of clay and 20kg of water Form a sphere with a diameter of 5mm to 8mm, that is, the ceramsite core. Wherein the sawdust rot treatment agent is a mixed solution of 90% rotten wood and 10% water by weight, the rotten wood is the product of wood or sawdust completely decayed by wood rot fungi, and the wood rot fungi are polypore fungus wood rot fungi and agaric Wood-rotting fungi or Borealis-like wood-rotting fungi; the particle size of sawdust is 100 μm to 150 μm; the particle size of clay is not more than 45 μm.

[0016] (2) Preparation of ceramsite shell mixture: 90kg of cement, 180kg of river sand, 10kg of chemical fertilizer, 2kg of fertilizer slow-release agent, 5kg of color hardener, 0.5kg of color retention agent an...

Embodiment 2

[0020] Embodiment 2 The ceramsite core body 6 is mixed and extruded into a sphere with a diameter of 5 mm to 8 mm according to the weight ratio of 100 kg of sawdust, 20 kg of sawdust decay treatment agent, 5 kg of clay and 25 kg of water; 200kg of river sand, 15kg of chemical fertilizer, 2.5kg of fertilizer slow-release agent, 6.5kg of color hardener, 0.8kg of color retention agent and 4kg of brightener are mixed and prepared in parts by weight; Sawdust decay treatment agent 5kg was soaked for 24 hours and prepared, other methods and steps were the same as those in Example 1, and the bulk density of the ceramsite itself after the central cavity 4 was formed was 300kg / m 3 ~450kg / m 3 .

Embodiment 3

[0021] Embodiment 3 The ceramsite core body 6 is mixed and extruded into a sphere with a diameter of 5 mm to 8 mm according to the weight ratio of 120 kg of sawdust, 25 kg of sawdust decay treatment agent, 6 kg of clay and 30 kg of water; 220kg of river sand, 20kg of chemical fertilizer, 3kg of fertilizer slow-release agent, 8kg of color hardener, 1kg of color retention agent and 5kg of brightener are mixed and prepared in parts by weight; Sawdust decay treatment agent 6kg was soaked for 24 hours and prepared, other methods and steps were the same as those in Example 1, and the bulk density of the ceramsite itself after the central cavity 4 was formed was 350kg / m 3 ~480kg / m 3 .

Abstract

The invention discloses a preparation method of gardening hollow non-sintered ceramsite, and relates to the field of ceramsite processing. The problems that existing solid ceramsite is large in stacking density, low in water absorption rate, not high in fertilizer storage capacity and the like are solved. The method includes the steps of preparing ceramsite core bodies from saw dust, a saw dust rotting treating agent, clay and water, preparing ceramsite shells from cement, river sand, flower fertilizer, a fertilizer slow release agent, a colorful hardening agent, a color fasting agent and a brightening agent, and then preparing the gardening hollow non-sintered ceramsite. The method is simple in process, environmentally friendly and capable of saving energy, the ceramsite is low in density, and the water storage and nutrient storage capacity of the ceramsite is greatly improved.

Description

technical field [0001] The invention relates to a technology for manufacturing ceramsite, in particular to a method for preparing horticultural hollow unfired ceramsite. Background technique [0002] Ceramsite has many excellent properties, such as low density, high cylinder compressive strength, and fire resistance, so it is widely used in building materials, gardening, food and beverage, refractory insulation materials, and chemical industries. With the acceleration of urban construction, the application of ceramsite is also developing faster. The amount of ceramsite used in horticulture in my country is expected to reach more than 15% of the total output in 2016. However, the ceramsite used in horticulture in our country is basically produced by sintering, and the internal structure of ceramsite products is solid. In particular, the solid ceramsite has a low water absorption rate and low nutrient storage capacity. This is due to the small internal voids of the ceramsite ...
