Utility model patent CN201220326750 discloses a rock wool setting system with wrinkling function, but it does not disclose details of how to achieve wrinkling
Chinese patent application 201010512495.8 discloses a rock wool pleating machine, which realizes the pleating of rock wool through the speed difference of multiple sets of upper and lower pressure rollers. The products obtained by this pleating method make each rock wool layer wrinkle. Wrinkles produce component force in the thickness direction, which is beneficial to improve the peel strength of rock wool products, but according to the product principle, it can not establish a connection between layers, so the effect on improving the peel strength is limited, and the actual sales in the market The product also confirms this
Another disadvantage is that the undulating folds in the rock wool product actually increase the tensile allowance of the rock wool layer in the longitudinal direction, giving the rock wool product more elasticity in the longitudinal and thickness directions. , this property is often not desirable

Embodiment 1
[0027] Embodiment 1: 75 parts by weight of basalt, 6 parts of limestone, 5 parts of slag, 25 parts of coke, 3 parts of fluorite, and 1 part of diatomaceous earth are mixed and pulverized and added to the cupola. Enter liquid oxygen, melt, and magma is formed into fibers through a four-roller centrifuge, and the exit is sprayed with phenolic resin binder and hydrophilic agent to prepare a solution. After cotton collection and pendulum machine laying, it enters the cotton press machine and is made after solidification. Three-dimensional structure rock wool.

The invention discloses a method for preparing agricultural rock wool. The method comprises the following steps: preparing mixed raw materials from the following components in parts by weight: 70-80 parts of basalt, 5-8 parts of limestone, 3-5 parts of slag, 20-30 parts of coke and 3-5 parts of auxiliary materials, adding the materials into a cupola furnace to be fused into magma, performing fiber forming and wool collecting and paving, pressing on a three-dimensional cotton presser, curing, and finishing, thereby obtaining the agricultural rock wool. The prepared agricultural rock wool has excellent mechanical property and is suitable for various conditions.
Description
technical field [0001] The invention relates to the field of new rock wool materials, in particular to a method for manufacturing agricultural rock wool. Background technique [0002] Agricultural rock wool is currently recognized as a very ideal substrate for soilless cultivation. However, the existing agricultural rock wool material has a very important disadvantage, that is, the material strength is not enough, especially when it is used as the base material of the three-dimensional green wall, it is easy to peel off. [0003] One of the solutions to improve the peel strength of agricultural rock wool is to use stronger adhesives, but there will be environmental problems and the effect is not ideal. Another way is to pleat the layers of rock wool during the manufacturing process. Utility model patent CN201220326750 discloses a rock wool sizing system with wrinkling function, but it does not disclose the details of how to achieve wrinkling. Chinese patent application 20...
