Abstract
Waste PVC plastic and rice straw are treated by cleaning, crushing in crusher, grinding into fine powder below 100 mesh, mixing with solvent and starch and beating in grinding machine into semitransparent mixture, which is sprayed evenly in pelletizing machine onto solid grains of pesticide or fertilizer to form coating after natural cooling. The said method relizes delayed release of pesticide or fertilizer. Utilizing waste PVC plastic and rice straw is fabourable to environment protection.
Description
The present invention relates to a kind of agricultural chemicals, fertilizer dressing and processing method thereof.
Execute the stimulation of agricultural chemicals in the farmland, fertilizer for minimizing, itself decompose and prevent rainwater or irritate ground water and wash away loss, seen the foreign data report, agricultural chemicals, fertilizer are reached the purpose of slowly-releasing with sulphur or resin as dressing crop.Because China's sulphur resource is less, resin is made dressing cost height, is not suitable for China's national situation.
The object of the present invention is to provide a kind of agricultural chemicals, fertilizer dressing and processing method thereof, adopt waste vinylene chloride plastic and rice field stalk etc. to make raw material, be processed into the dressing of agricultural chemicals, fertilizer, reach the purpose of slowly-releasing, be fit to the needs of China's national situation.
The present invention realizes like this.Utilize hydroxyl in the waste vinylene chloride plastic molecule and the hydroxyl in natural polymer polymer (rice field stalk, the starch etc.) molecule to have good blend, broken by its hydrogen bond of adjustment (near the boiling point of solvent), the hydroxyl that is in the association state becomes " dissociating " state gradually, " dissociating " hydroxyl still can associate again when utilizing cooling, makes the affinity increase of waste vinylene chloride plastic and natural polymer polymer and forms thin film on obducent surface.Owing to be rich in this film and be beneficial to biodegradable cellulose and hemicellulose (rice field stalk, starch), particularly when suction, the starch in the film sharply expands, and makes film breaks and agricultural chemicals or fertilizer are dissolved in soil are absorbed by crop.Regulate the ratio of plastics and rice field stalk, starch, the thickness of control film can be regulated water absorption, absorption speed and the absorbent time of film, thereby reaches the rupture time of control dressing.
Specific implementation method is at first with waste vinylene chloride plastic, the rice field stalk is through removal of impurities, after the cleaning, add 25-35% (weight meter respectively, as follows), 12.5%, by the cracker meal, again through the flour mill fine powder below 100 orders, (solvent is by oxolane 23.5% to add solvent 50% again, dibutyl tin laurate 0.5%, first isobutyl ketone 5.5%, MEK 47%, waste polyvinyl chloride 23.5% is formed), starch 12.5-2.5%, in sand mill, pull an oar into transparence, be preheated to the 60-70 degree then, solid granular agricultural chemicals or the fertilizer of desiring dressing are put into evenly spray film of nodulizer, naturally cool to normal temperature and promptly finish dressing.
The agricultural chemicals or the fertilizer of the band dressing of making by above-mentioned processing method, because the ratio of plastics and rice field stalk, starch in the dressing, the thickness before the bag needs to control by crop, the rupture time difference of dressing, thus reach the purpose of slowly-releasing.When farmland operation, can will be with dressing agricultural chemicals or fertilizer to go to the field simultaneously in sowing, agricultural chemicals or fertilizer need to discharge when the time comes by crop.Promptly save man-hour, fertilizer, do not miss farming season again, satisfy the plant growth needs, the utilization of waste polyvinyl chloride and rice field stalk also helps environmental protection.
Embodiment:
Solvent burden ratio: oxolane 100Kg dibutyl tin laurate 1.5Kg first isobutyl ketone 25Kg MEK 200Kg, waste polyvinyl chloride 100Kg mix standby.
Rice field stalk and waste polyvinyl chloride after removal of impurities, cleaning, by the cracker meal, again through the flour mill fine powder to standby below 100 orders.
1, coated formula (to produce the 100Kg dressing): the dressing required time 40 days (positive and negative 10 days) that breaks
Waste polyvinyl chloride 25Kg rice field stalk 12.5Kg starch 12.5Kg solvent 50Kg.
2, No. two bag table prescriptions (to produce the 100Kg dressing): the dressing required time 70 days (positive and negative 20 days) that breaks
Waste polyvinyl chloride 30Kg rice field stalk 12.5Kg starch 7.5Kg solvent 50Kg.
3, No. three coated formula (to produce the 100Kg dressing): the dressing required time 90 days (positive and negative 20 days) that breaks
Waste polyvinyl chloride 35Kg rice field stalk 12.5Kg starch 2.5Kg solvent 50Kg.
Band dressing agricultural chemicals or the fertilizer made by above-mentioned coated formula and processing method, because the ratio of plastics and rice field stalk, starch in the dressing, the thickness of dressing needs to control by crop, the rupture time difference of dressing, thus reach the purpose of slowly-releasing.When farmland operation, can will go to the field with the agricultural chemicals or the fertilizer of dressing simultaneously in sowing, agricultural chemicals or fertilizer need to discharge when the time comes by crop.Promptly save man-hour, fertilizer, do not miss farming season again, satisfy the plant growth needs.The utilization of waste polyvinyl chloride and rice field stalk also helps environmental protection.
Claims (2)
1, a kind of agricultural chemicals, fertilizer dressing is characterized in that being made up of waste vinylene chloride plastic 25-35%, rice field stalk 12.5%, solvent 50%, starch 12.5-2.5%.
2, the processing method of a kind of agricultural chemicals, fertilizer dressing, it is characterized in that earlier waste vinylene chloride plastic, rice field stalk after removal of impurities, cleaning, by the cracker meal, again through the flour mill fine powder below 100 orders, add solvent, starch in proportion, in sand mill, pull an oar into translucently, be preheated to the 60-70 degree then, solid granular agricultural chemicals or the fertilizer of desiring dressing are put into evenly spray film of nodulizer, naturally cool to normal temperature.
