In a company in the “China toothbrush capital†Qijianghang Township, he witnessed the transformation of straw magical plastics.
At the Jiangsu Xinyuanyuan Daily Chemical Co., Ltd. natural straw plastics production plant, the reporter saw that the machinery in the factory roared, and the bundles of straw were finely chopped into a powder after being streamlined. Subsequently, the workers added lubricants and a chemical material called polylactic acid to the "straw powder." According to the technicians, the mysteries of plastics changed from straw to straw. Polylactic acid is a kind of polymer material made from plant raw materials. It can be degraded by itself and becomes a paste at a temperature of 200 degrees Celsius. Its plasticity is very high. Strong, and can return to solid at room temperature, adding straw fiber can strengthen its strength. The processed paste mixture is finally granulated and turned into solid, solid, small particles at room temperature. Like ordinary plastics, these pellets can be made into plastic toothbrushes, bowls and scoops, combs, and Other products through injection molding, blow molding, and blister molding.
Remember that these straw plastic particles smelled, there is no "plastic taste", but there is a straw fragrance. The chairman of the company, Yin Zhengfu, introduced that the straw content in straw plastic was nearly 40%, so it smelled of straw. Two years ago, the company and Tongji University jointly developed this straw modification blending technology, which filled in the gaps in international and domestic straw utilization technology and obtained national patents. The biggest advantage of straw plastic is environmental protection, reducing the dependence on petroleum, and the toothbrush made can be recycled and reused. Under composting conditions, more than 95% of degradation can be achieved within 6 months. The dust generated during the production of straw plastics is separated from the electrostatic precipitator and can be added back to the raw materials to achieve “zero emissionsâ€.
It is understood that hotel supplies made of traditional plastics are now difficult to sell in the high-end market because environmental protection is not up to standard, and straw plastics are adapting to the needs of this segment of customers. Compared with the use of traditional plastics, the company's raw material costs are reduced by 10%-15%. According to the person in charge of the company, it is estimated that 30 tons of straw plastics will be produced per day after mass production, and more than 10 tons of straw will be needed each day to meet production requirements. The enterprises have already purchased and purchased in the surrounding areas. The purchase price is 500 yuan/mu. After deducting collection, transportation and other expenses, the farmer's straw per mu can increase more than 100 yuan.
