The water retaining agent equipment of Weifang customer in Shandong province is 38 meters long and 1.85 meters wide. The current power is 100KW, but the whole equipment is designed according to 150KW power, which is convenient for later equipment upgrading.
The initial moisture of the water retaining agent is about 20%, and the client’s process requires drying to about 7%-8%.
The water-retaining agent is dried and then granular through a granulator.
The drying temperature of the product should not be too high, so the equipment design is longer than the conventional equipment, because the temperature should be controlled, which is similar to the microwave sterilization equipment.
In the drying process, the drying and dehydration efficiency is generally at a temperature of about 80 degrees, which basically conforms to the dehydration law of 1KW microwave magnetron tube dewatering 1kg per hour.
The water-retaining agent is similar to an organic fertilizer. The water-retaining agent uses super absorbent resin, which is a kind of functional polymer material with strong water-absorbing capacity.The biggest characteristic is that water retention is very good.According to its technological requirements,1 gram of water preservative can absorb 300 grams of water, which is suitable for dry areas in north or northwest China, such as xinjiang, Inner Mongolia, Tibet and other dry areas to plant crops and trees nursery.In the process of planting, water retaining agent is put into the ground and then irrigated with water. The water retaining agent can absorb the water and do not need to be irrigated for a year.Then the water retention agent slowly evaporates the water, and the water contains a special organic fertilizer that also promotes plant growth.
Water-retaining agent is insoluble in water and has the function of water-retaining, fertilizer preserving and heat preservation improving soil structure.
