Problems solved by technology

[0002] Today's household biogas generators are mainly made of cement mortar, bricks, concrete, etc. The construction period is long and leakage often occurs, which may even cause the biogas generator to be scrapped.
Secondly, it is made of glass fiber and thermosetting resin, which is a fiberglass biogas generator. Its advantage is that the leakage of biogas has been greatly improved, but the production efficiency is low and the price is high.
At present, there is no use of modified plastics to prepare biogas generators by injection molding.

Embodiment

[0010] Example: Preparation of Modified Polypropylene and Its Injection Molding

[0011] Weigh 100 parts of polypropylene by weight, 15 parts of ultra-high molecular weight polyethylene, 25 parts of EVA, 15 parts of EPDM rubber (granular), 45 parts of superfine calcium carbonate, and 25 parts of superfine talcum powder. Add to LDH mixer and mix for 20 minutes. Add the mixed material into the feeding hopper of the twin-screw extruder. The temperature of the extruder is controlled in sections. The temperature of each section from the feeding section to the extrusion section is as follows: 150~160°C, 165~170°C, 170°C ~180℃, 180~190℃, 195~205℃. After extrusion, it is drawn and cooled in a water tank, and then pelletized by a pelletizer for injection molding.

[0012] During injection molding, the temperature of the barrel is controlled in sections from the feeding section to the nozzle. The temperature of each section is as follows: 155°C, 160-165°C, 170-185°C, the temperature o...

Abstract

The invention discloses a preparation material and process for household marsh gas generator, wherein the material is prepared from polypropylene, polyethylene, ethane-vinyl acetate copolymerized resin, EPT rubber, calcium carbonate, talcum powder by a finite proportion.

Description

technical field [0001] The invention relates to the use of thermoplastic modified polypropylene as raw material to produce household biogas generator parts by a plastic injection molding method with high production efficiency. The invention relates to the preparation material and the preparation method of the parts of the biogas generator. Background technique [0002] Today's household biogas generators are mainly made of cement mortar, bricks, concrete, etc. The construction period is long and leakage often occurs, which may even cause the biogas generator to be scrapped. Secondly, it is made of glass fiber and thermosetting resin, which is a fiberglass biogas generator. Its advantage is that the leakage of biogas has been greatly improved, but the production efficiency is low and the price is high. At present, there is no use of modified plastics to prepare biogas generators by injection molding. Therefore, such research and development have been carried out. Modified ...
