Rubber powder is prepared by using waste rubber products, mainly waste tires, as raw materials, through different crushing methods such as room temperature crushing, freezing and other methods, and then screening and removing waste rubber components, which is one of the main ways of waste rubber recycling. The mainland is a big country in agricultural production, in-depth research on the application of rubber powder in the field of agriculture, can process more waste rubber products, Xiaobian today to share with you the following rubber powder in agricultural tires, agricultural irrigation pipes and soil improvement applications.
1. Application of rubber powder in agricultural tires
Agricultural tractor is an important tool for harrow operation, agricultural tractor tires are required to work on country roads, hard stubble land, tires are easy to be scratched and cut when working, tire tread rubber is required to have good wear resistance, puncture resistance, sidewall rubber has good cutting resistance, flexural crack resistance and aging resistance. In actual production, the tread rubber and sidewall rubber of agricultural tractor tires are generally processed with natural rubber, natural rubber/butadiene rubber, natural rubber/styrene-butadiene rubber, and natural rubber/styrene-butadiene rubber/butadiene rubber.
5-20 parts of fine rubber powder can be mixed with tractor tire tread rubber, and the interface characteristics of rubber powder and rubber blending can be used to improve the tear resistance and dynamic fatigue resistance of tractor tire tread rubber and reduce the heat generated during tire driving. It is generally recommended to mix 10-20 parts of vulcanized rubber powder 2ELYY1011WFM in the sidewall rubber of tractor tires to significantly improve the flexural resistance of the sidewall rubber. In actual production, activated rubber powder can also be used in agricultural tractor tires, and the mixing effect is better, and the mixing amount can be appropriately increased.
2. Application of rubber powder in irrigation water pipes
The main methods of agricultural irrigation are drip irrigation, sprinkler irrigation and micro-sprinkling, drip irrigation is a common irrigation method of using water droplets to water the soil, using a low-pressure pipeline system to dissolve the water dissolved in the fertilizer fertilizer slowly drip into the soil of the root of crops regularly and quickly. In the drip irrigation operation, the drip irrigation water pipe can be processed with rubber powder as the main raw material, and the drip irrigation hose made of rubber powder and PE is blended and extruded at a ratio of 7:3, which is widely used in agricultural production.
Large-diameter irrigation water pipes are generally processed with natural rubber as the main raw material, and 100-200 parts of rubber powder can be added to 100 parts of raw rubber, which can not only reduce the cost of rubber water pipe raw materials, but also reduce the deformation of semi-finished products, which is conducive to exhaust, and the fatigue resistance of finished products is better.
3. Application of rubber powder in soil improvement
In recent years, the desertification of mainland land is serious, and it is necessary to manage land desertification and improve soil, and the soil amendment with waste rubber powder as the main raw material has a good improvement effect on barren land, and rubber powder can promote the improvement effect of the amendment on the soil. In the preparation process, the amount of rubber powder can be controlled at about 60-70 parts, add 30-40 parts of desulfurization waste (mostly desulfurization gypsum, etc.), prepared with a small amount of accelerator, if necessary, it can also be used is Olin organic fertilizer, microbial fertilizer, etc.
The application of rubber powder in agricultural production is not limited to this, and the editor will continue to share with you other applications and application skills of rubber powder in the agricultural field.
