Description

1. Technical field [0001] The invention relates to a product made of a polymer material, more particularly to a preparation material and a preparation method of an anaerobic fermentation device and its product. 2. Background technology [0002] Today's anaerobic fermentation devices are mainly made of cement, mortar, brick or concrete. Long construction period, troublesome maintenance, easy cracks and leakage, and even scrapping. Others are made of glass fiber and thermosetting resin, which has the advantage of improving the leakage problem, but the production efficiency is low and the cost is high. So far, there is no one using nano-modified polypropylene and other polymer compounds as raw materials to prepare an anaerobic fermentation device through large-scale injection molding. 3. Contents of the invention [0003] One of the objectives of the present invention is to provide a preparation material for an anaerobic fermentation device. [0004] The second object of t...
