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 Wherein, the rotational speed of the first-order screw extruder is set to 130-180rpm / min, and the first-order screw extruder is divided into seven continuous melt plasticizing 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 frame, and the glass fiber is me...

Abstract

The invention provides a light and high-strength dung leakage plate LFT-D forming process. The process comprises the following steps: (10) resin PP is quantified according to the weight of a template, is then heated and fused in a first-order double-screw extruder, and is sent to a feed port of a second-order double-screw extruder; (20) the fused PP and glass fiber are synchronously fed in the second-order double-screw extruder for mixed plastifying, and are extruded; (30) after being uniformly plastified by the second-order double-screw extruder, the raw material is cut by a second-order screw mold orifice cutter according to the weight of the dung leakage plate, and is conveyed to a taking displacement position with the temperature being preserved; and (40) a plurality of channel steels are arranged in a prefabricated mold side by side, and are suspended in the mold; and the raw material is taken into the press mold for compression molding to obtain a product. The dung leakage plate produced with the forming process has the advantages of light weight, enough strength and rigidity, durability and easy cleaning.

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...
