Abstract

The invention discloses a production process for a forming substrate. The production process comprises the following steps: pre-pressing a mixture, performing second pressing on the pre-pressed mixture, and controlling the pre-pressing pressure to be less than the second pressing pressure; applying a pressure to the mixture by utilizing a small pre-pressing pressure, enabling a place with many mixtures to collapse, wherein the mixtures are slide to a place with few mixtures, the mixtures are leveled, and the mixtures are not compacted at a low pre-pressing pressure; performing second pressingby utilizing a high pressure, and enabling to form uniform pores inside a forming composition, so that water absorption and air circulation are facilitated by the uniform pores, and the total pore space and water absorption rate of the forming composition are further wholly improved; and performing microwave treatment and air-cooling treatment, thereby obtaining the forming substrate. According tothe uniform pores inside the forming composition, microwave treatment as well as moisture volatilization and gas circulation in the air-cooling treatment process are facilitated, rapid curing formingand dredging of the pores are conveniently performed, and the total pore space and water absorption property of the forming substrate are improved.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation, and in particular relates to a production process of a forming substrate, in particular to a production process of a planting brick. Background technique [0002] The molding substrate is obtained after the cultivation substrate is molded, and has a fixed shape. For example, the American planting brick is a molding substrate, which is conveniently applied to the small spaces of residents (such as roofs, balconies, and terraces, etc.) or the roofs of enterprise factories. It is mainly made of organic materials such as crop stalks, soybean cakes, and livestock and poultry manure after harmless treatment. It really achieves the purpose of planting crops without soil, pesticides and chemical fertilizers. It only needs to be watered and exposed to sunlight, and the seeds can grow vigorously. The planting is cycled throughout the year, which has huge environmental and economic benefits. ...
