Embodiment Construction

[0032] Such as figure 1 As shown, the lightweight and high-strength leaking dung panel LFT-D molding process of the present invention includes:

[0033] Step 10. Quantify the resin PP from the vacuum feeding system to the vector weighing system according to the weight of the template, and then enter the first-stage twin-screw extruder for heating and melting; the melted PP is sent to the second-stage twin-screw extruder for feeding Among them, the speed of the first-order screw extruder is set to 130-180r / min, and the first-order screw extruder is divided into seven continuous melting zones D1~D6 and D machine head, wherein the temperature of D1 is 180 -220°C, the temperature of D2 is 190-230°C, the temperature of D3 is 210-240°C, the temperature of D4~D6 is 215-240°C, and the temperature of D head is 215-240°C;

[0034] At the same time, the glass fiber is sent to the second-stage twin-screw machine through the glass fiber rack, and the glass fiber is measured and cut by the...

Abstract

The present invention provides a light-weight and high-strength LFT-D molding process for leaky dung panels, including step 10, quantifying the resin PP according to the weight of the template, and then entering the first-stage twin-screw extruder for heating and melting; then sending it to the second-stage twin-screw extruder The feed inlet of the machine; step 20, the melted PP and glass fiber enter the second-stage twin-screw extruder at the same time for mixing and plasticization, and then extrude; step 30, after the second-stage twin-screw extruder is plasticized evenly, the After the material is cut off by the second-stage screw die mouth cutter according to the weight of the leaking manure board, it is then transported to the displacement position of the material with heat preservation; step 40, placing a plurality of channel steels side by side in the prefabricated mold, and the channel steels are hung on the In the mold, the raw material is then taken and placed into the mold of the press for compression molding to obtain the product. The dung leaking board manufactured by the molding process of the invention is light in weight, sufficient in strength and rigidity, durable and easy to clean.

Description

technical field [0001] The invention relates to a light-weight and high-strength LFT-D forming process of a leaky dung board. Background technique [0002] At present, the types of slats used more in the field of agriculture and animal husbandry mainly include cement slats, cast iron slats and injection molded slats. Analyzed from two aspects of performance and economic benefits, its characteristics are as follows: [0003] [0004] Apparently, the above-mentioned leaking manure board cannot be well adapted to the current production needs, and further improvement is needed. For this, the applicant applied for a utility model with the application number 201420229850.4 on May 07, 2014, which discloses a Lightweight and high-strength feces leaking board, which includes a plastic panel and a plurality of plastic reinforcing ribs on the back of the plastic panel, the plastic panel is provided with leaking holes, and the plastic panel and the plastic reinforcing ribs are space...
