January 1, 2021 is the first day the national ban on plastic and straws takes effect. Biodegradable plastics are the first choice to replace non-degradable plastics, and biodegradable modified plastics have also become a new hotspot for recent market development.
Nanjing KY Chemical Machinery Co., Ltd. entered the field of biodegradable plastics in the 1990s, independently developed the twin screw extruder machine suitable for biodegradable modified plastics, and successfully delivered 2 sets of TE95 twin screw extruder machines for Tianjin Danhai biodegradable modified plastics. In the following years, many well-known degradable plastics manufacturers purchased several sets of twin screw extruder machines for degradable plastics developed by KY, and expressed a high degree of recognition for the performance of KY's products.
Driven by national policies, the degradable plastics market has ushered in a new development trend. The market for starch-based degradable plastic modified materials has flourished. In order to better seize market opportunities, Mr. Liu Guangzhi, Chairman of KY, personally led the company's technical R&D personnel to race against time. Based on the third-generation HK and SK series twin screw extruder machine technology, several models of special functional screw elements for plastic modification granulation suitable for the degradation of PLA and PBAT have been developed and produced, which breaks through the production bottleneck of low rotate speed and low production capacity of the driving screw of the degraded modified material at one fell swoop.
Compared with the traditional models on the market, the third-generation HK and SK series twin screw extruder machines have higher capacity for processing degradable modified materials and better material performance! According to the user's on-site test, the production capacity of the HK73 main machine is increased by more than 100% compared with the traditional 75 machine under the working condition of 400rpm screw speed, and the single machine production capacity can reach 400 to 500kg/h. The material has excellent performance after cooling and granulation, and it will not cause problems such as the yellowing of the material color due to the increase of the screw speed, which has been unanimously recognized by users.
In December 2020, in just one month, KY delivered more than 20 sets of twin screw extruder machines for degradable modified materials. At the same time, KY has assembled R&D technical strength to develop a new cooling and granulation auxiliary machine system, and is committed to increasing the single-machine capacity of degradable modified materials to another level.
In recent years, the "one-step" process technology of KY's third-generation HK and SK intelligent twin screw extruder machines has been gradually improved, which can provide users with a complete set of machine that can achieve one-step blown film and one-step extruded sheet materials for degradable modified plastics, which eliminates the user's repeated investment in pelleting and extrusion molding equipment, and reduces the waste of energy consumption in the secondary melting process of the degraded modified material. The vigorous promotion and application of this "one-step" technology has reduced input costs and created higher value for more users, and is deeply loved and trusted by users.
