Problems solved by technology

[0003] At present, PVC soft water belts are widely used in agricultural water belts. The disadvantage of this kind of water belts is high cost. The density of PVC resin is 40% higher than that of EVA resin, and the unit price of PVC resin is higher than that of EVA resin. PVC resin is not easy to degrade and does not meet environmental protection requirements. Unable to enter the European and American markets, the disadvantages of another EVA braided water hose are: it needs to be turned over and bonded, so the production process is complicated, the production efficiency is low, it is not easy to control the bonding quality stably, and it is easy to peel off the glue, so the market sales volume is very small

Embodiment Construction

[0018] attached figure 1 It is a specific embodiment of the present invention. This invention a kind of production technology of plastic water softener, comprises the following steps:

[0019] 1. Fix the warps required for the manufacture of EVA soft water belts on the brackets of the two pay-off racks respectively. Place 80 100D twisted polyester threads on each pay-off rack, and install 160 wire spindles in total. The warp threads are tightened by each wire spindle. After adjusting the tightness, the wire device passes through the bracket inlaid with porcelain eyes in turn, and then passes through the front and rear discs of the guide rod of the winding machine and the weft thread under the traction of the winder, and enters the die head of the plastic extruder together.

[0020] 2. The front and rear discs of the winding machine are respectively equipped with 24 wire storage cylinders, and 80D polyester thread ingots are placed in the cylinders, and each thread is adjusted...

Abstract

The invention belongs to the technical field of plastic soft water bands and in particular relates to a production technology for the plastic soft water band, aiming at overcoming the shortcoming that PVC (polyvinyl chloride) resin is difficult to degrade. The production technology can well meet environment protection laws and regulations home and abroad; the density of EVA (ethylene-vinyl acetate) resin is lower than that of the PVC resin, so that the unit weight ratio of an EVA water band is reduced by 30-40 percent when being compared with the unit weight of a PVC water band; compared with an EVA woven water band, the plastic soft water band overcomes the shortcomings of low production efficiency, high cost and easiness in stripping of an adhesive layer as the EVA woven water band is required to be turned to be adhered; requirements of high efficiency, low consumption and high quality are met.

Description

technical field [0001] The invention belongs to the technical field of plastic water softeners, in particular to a production process of plastic water softeners. Background technique [0002] The resin materials required for the production of hoses are petrochemical products, and petroleum resources are non-renewable resources. This design can reduce resin consumption without affecting product quality. Therefore, this design invention saves energy, is beneficial to environmental protection, and can contribute to agricultural production. Provide high quality and cheap products. [0003] At present, PVC soft water belts are widely used in agricultural water belts. The disadvantage of this kind of water belts is high cost. The density of PVC resin is 40% higher than that of EVA resin, and the unit price of PVC resin is higher than that of EVA resin. PVC resin is not easy to degrade and does not meet environmental protection requirements. Unable to enter the European and Americ...
