Rubber powder is made from waste rubber products, mainly waste tires, by crushing, screening and removing waste rubber components through different crushing methods such as room temperature crushing, freezing, etc. It is one of the main ways of recycling waste rubber. China is a large agricultural production country. We have deeply studied the application of rubber powder in the agricultural field and can handle more waste rubber products. Xiao Bian will share with you today the following applications of rubber powder in agricultural tires, agricultural irrigation pipes and soil improvement.
1. Application of rubber powder in agricultural tires
Agricultural tractors are important tools for plowing and harrowing operations. The tires of agricultural tractors are required to work on rural roads and hard stubble ground. The tires are easy to be scratched and cut when working. The tire tread rubber is required to have good wear resistance, puncture resistance, and the tire sidewall rubber has good cutting resistance, flex cracking resistance, and aging resistance. In actual production, agricultural tractor tire tread rubber and sidewall rubber are generally processed from natural rubber, natural rubber/polybutadiene rubber, natural rubber/styrene butadiene rubber and natural rubber/styrene butadiene rubber/polybutadiene rubber blends.
The tractor tire tread can be mixed with 5-20 phr of fine rubber powder. The tear resistance and dynamic fatigue resistance of the tractor tire tread can be improved by using the interface characteristics of the rubber powder and rubber blend, and the heat generated during driving can be reduced. It is generally recommended to mix 10-20 phr of vulcanized rubber powder 2ELYY1011 into the sidewall rubber of tractor tires to significantly improve the flex resistance of the sidewall rubber. In actual production, activated rubber powder can also be used in agricultural tractor tires, which has better mixing effect, and the mixing amount can be appropriately increased.
2. Application of rubber powder in irrigation water pipes
The main agricultural irrigation methods include drip irrigation, sprinkler irrigation and micro spraying. Drip irrigation is a common irrigation method that uses water droplets to water the soil. Water dissolved in chemical fertilizers is slowly and regularly dripped into the soil at the root of crops using a low-pressure pipeline system. In the drip irrigation operation, the drip irrigation water delivery pipe can be processed with rubber powder as the main raw material. The drip irrigation rubber pipe, which is extruded by mixing rubber powder and PE at a ratio of 7:3, has been widely used in agricultural production.
Large diameter irrigation water pipes are generally processed with natural rubber as the main raw material. 100-200 rubber powder can be added to 100 parts of raw rubber, which can not only reduce the raw material cost of rubber pipes, 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 land desertification is serious in our country, and it is necessary to manage the land desertification and improve the soil. The soil improver with waste rubber powder as the main raw material has a good improvement effect on the poor land, among which rubber powder can promote the improver's sudden improvement effect. In the preparation process, the amount of rubber powder can be controlled at about 60-70 parts. 30-40 parts of desulfurization waste (mostly desulfurization gypsum, etc.) are added and prepared with a small amount of accelerant. If necessary, Olin organic fertilizer and microbial fertilizer can also be used.
The application of rubber powder in agricultural production is not limited to this. Xiaobian will continue to share with you other applications and application skills of rubber powder in the agricultural field.
