Method for making ultra-thin drip tape

Patent name A method for making ultra-thin drip tape Patent applicant Shaanxi Peace Science & Technology Co., Ltd. Principal applicant Address 710075 Inventor Chen Zepei, Lan Xinmin, 21st Floor, Shanxi Securities Building, No. 1 Gaoxin 2nd Road, Gaoxin District, Xi'an, Shaanxi Province Patent No. 200510042699.9 Date of Application 2005.05.23 Issuing Date Approved Announcement No. 1695934 Date of Validation Announcement 2005.11.16 Manual CD-ROM D0546 Main Classification Number B29D23/00 Classification Number B29D23/00; B29C69/00 Sub-file Original Application No. Priority Item Abstract The invention relates to a method for making an ultra-thin drip tape. Method according to the following steps: Select raw materials; Weigh the raw materials; Dry processing of raw materials, into a low speed mixer to fully mix; Extruded in the extruder to meet the thickness and width requirements of the sheet; Then send the two groups of sheets into the constant temperature Oven; Preheated two groups of sheets are then fed into a vacuum suction machine, heated and pressed by a vacuum-absorbing roller to form a plurality of dripping-flow drip irrigation belts, and cooled and set; each is fed into a slitter and cut into individual pieces. Ultrathin drip tape. The method is characterized by a two-step processing method. The first step is to use an extruder to extrude the sheet that meets the thickness and width requirements; the thickness is 0.05 to 0.08 mm. The second step is to preheat the two sheets. Then the vacuum suction roller heat presses the ultrathin drip irrigation belt into a plurality of turbulent flow channels, the production speed is more than 100m per minute, and the sales price drops by a factor of two. Widely used in agriculture, forestry, green lawn and other industries. Has good social and economic benefits. Sovereignty item 1, a method for making an ultra-thin drip tape, according to the following steps: a, in accordance with the material composition of the ultra-thin drip tape selection of raw materials; b, in accordance with the proportion of ultra-thin drip tape material composition weighed; c. The weighed raw materials are subjected to a drying treatment at a treatment temperature of 60° C.-80° C. d. The raw materials after the drying treatment are mixed in a low-speed mixer and the mixing speed is 10-20 revolutions per minute. For 15-20 minutes, the mixed raw materials are put into a container for use; e, the raw materials to be used are put into an extruder and the sheets that meet the thickness and width requirements are ready to be used, ie the extrusion thickness is 0.05- 0.08mm, the temperature in the extruder is 180°C-210°C; f, the two sets of sheet materials that meet the thickness and width requirements of the extrusion are sent to the constant temperature oven for heating up to two layers. The oven temperature is 145°C-150. °C, the feeding speed is 10 meters per minute; g, the preheated two groups of sheets are fed into the vacuum suction machine at the same time, the vacuum degree of the vacuum suction machine is 200mmHg, and the vacuum suction roller heat presses the plastic into Multiple turbulent flow paths with drip tape, cooling and setting; h, will However, a plurality of drip irrigation belts that have been shaped are then fed into a slitter to be cut into single ultrathin drip irrigation belts and finished products are finished. i. The ultrathin drip irrigation belts produced through the above steps are passed through quality inspection, packaging, storage, and delivery. Sales.
