Agricultural and livestock waste produced in large quantities, if not properly processed, will not only take up space, but also affect environmental sanitation and reduce the quality of life; if left to be discarded or incinerated, it will It may cause secondary pollution of water, soil and air. Composting the valuable organic materials in these wastes and returning them to farmland soil can not only solve the waste problem, but also increase soil fertility. Compost is a great option. Below ptfe compost film manufacturer will take you to understand the relevant content.
Nano membrane fermentation technology, we must first understand nanomembranes. In fact, nanofilm is a film with a smooth surface, uniform color, no cracks, impurities and holes, and a nanometer-scale pore size. This nanomembrane has selective permeability: small molecular gases such as water vapor and carbon dioxide can pass through, but it can prevent large molecules such as odor from passing through. This is one of the reasons why many farms usually choose nanomembrane fermentation technology when processing livestock and poultry manure.
In fact, ptfe compost film manufacturer materials can satisfy. Nanomembrane is also called e-PTFE molecular membrane. The water vapor and carbon dioxide produced during the fermentation process can diffuse out of the microporous structure of the membrane, while odor molecules such as ammonia dissolve in the water vapor in the inner layer of the membrane and then drip back into the stack to be further decomposed, which reduces The emission of odor increases the nitrogen content of compost. Outside rain and snow cannot penetrate into the membrane, so it can be operated in the open air and reduce investment.
The process of aerobic composting membrane fermentation is to select raw materials. The raw materials can be livestock and poultry manure, kitchen waste, straw vegetables, municipal sludge, etc. The raw materials are mixed with carbon auxiliary materials and fermentation strains. During the mixing, the moisture content and carbon-nitrogen ratio of the premix are adjusted, and several aeration pipes are laid in the fermentation tank. After the premix is mixed, it is stacked into a pile with a height of 1.5 to 2 meters in the fermentation tank through a forklift or conveyor. Fermentation treatment: Cover the surface of the pile with a nanofilm, and use temperature, humidity and oxygen concentration sensors to monitor changes in temperature, humidity and oxygen concentration of the pile in real time. Under sufficient oxygen supply and suitable moisture conditions, fermentation will be completed in 15-20 days.
The core equipment of the e-PTFE membrane covered system is covered on the pile of organic waste (livestock and poultry manure, sludge, domestic garbage, vegetable residues, etc.) of compost film. PTFE Compost Membrane Manufacturer The membrane is composed of an e-PTFE membrane and a substrate. It is sandwiched between two layers of strong polyurethane substrate membranes. The e-PTFE membrane is evenly distributed with 0.2μm pores, while the polyurethane membrane is UV-resistant and corrosion-resistant.
The ptfe nano-aerobic compost membrane currently produced by ptfe compost film manufacturer is the core material of composting technology and has good hydrophobicity and breathability Performance, the interlaced microporous structure of the fibers well blocks the entry of water molecules, while the good porosity allows air circulation.
