The biodegradable materials produced by Anhui Xinke Bio-environmental Protection Co., Ltd. can be degraded completely and rapidly in soil and natural environment according to the design requirements. They are non-toxic, non-polluting and odorless. After degradation, they will not destroy the soil structure. They are truly "from nature, but also from nature", and they are the preferred substitute for plastic and paper packaging. The company has always put the continuous improvement of product quality in the first place, repeated tests in product development, strict checks in the production process, so that the company's product quality continues to improve. Now it has successfully stepped out of the country and entered the international market, the company has also achieved higher economic and social benefits.
Polylactide is a kind of biodegradable plastic which can be used as packaging material in recent years. It has broad application prospects. The raw material of polylactide is lactic acid. The molecule of lactic acid has both hydroxyl and carboxyl functional groups. It has high reaction activity and is easy to dehydrate and condensate to polylactic acid under appropriate conditions. Poly (lactide) can be synthesized by direct polycondensation and ring-opening polymerization of lactide. Whether synthetic polylactide or fermented glucose, maltose, cereal juice or potato starch can be used to prepare biodegradable materials. The compost polylactide is degraded in about a month and can be absorbed by microorganisms in seawater.
Starch, PVA (polyvinyl alcohol) and polycaprolactone have good compatibility, and then participate in a variety of natural additives, so that the various functions of the product are close to or beyond the functions of general plastics. The production of this product has formed a common process in the whole process of mixing, granulation, extrusion, blow moulding and so on, which can be continuously and steadily industrialized. In recent ten years, plastics with its convenience and penetration into all walks of life, into millions of households, together with huge environmental pollution, the world and domestic environmental protection policies copyright, laws, environmental protection bills have been issued continuously, which proves that the demand for biodegradable plastics is gradually entering the standardization and industrialization, and the development of biodegradable plastics is entering a golden period of vigorous development. The company always adheres to the business philosophy of "honesty, quality, innovation and service", adheres to the development strategy of "technological breakthroughs and product innovations". It is brave to explore and make every effort to make all customers more satisfied with its strong company strength, high-quality product quality and perfect after-sales service.
Biofilm process and activated sludge process are both aerobic biological treatment methods. However, the activated sludge process relies on the activated sludge suspended in the aeration tank to decompose organic matter, while the biofilm process mainly relies on the microbial membrane fixed on the surface of the carrier to purify organic matter. It has the advantages of high treatment efficiency, shock load resistance, stable operation, small sludge production and economic and energy saving. Biofilm is an ecosystem composed of highly dense aerobic bacteria, anaerobic bacteria, facultative bacteria, fungi, protozoa and algae. The solid medium attached to it is called carrier, which is the core part of biofilm technology.
