NOVA undertakes the automatic sewing agent production line of 3 TREES

2021年11月，经过多轮角逐，综合专业行业技术（侧重）与商务条款间的对比，上海诺辉成功中标三棵树涂料股份有限公司（安徽工厂）美缝剂全自动生产线EPC项目，值得特别说明的是，在此之前，三棵树全国多个涂料生产基地，从未运用EPC总承包的模式新增产线设备建设，本次选择诺辉作为该模式在三棵树实际产线建设项目中首次运用，是基于诺辉特有的EPC项目管理经验，以及实地考察由诺辉承接的多个EPC总承包实例后的一次尝试，同时也是对诺辉作为国内专业的精细化工设备制造、系统集成成熟经验的肯定；

In November 2021,NOVAsuccessfullygotthe bid for the EPC project of3TREESCoatingsafter several rounds of competition between professional industry businessand technologytermswhich is more important.In particular, before this, many paint production bases of 3trees across the country have never used the EPC general contracting model to build new production line equipment. This time,NOVAis selected as the model for the actual production line construction project of 3trees, which is based onNOVA's unique EPC project management experience,as well as on-site investigation of several EPC general contracting examples undertaken byNOVA. At the same time, it is also an affirmation ofNOVA's mature experience as a professional fine chemical equipment manufacturer and system integration in China.

该生产线包括工艺设计、设备制作、钢结构搭建、现场安装、管道仪表系统、自动化控制系统等全部工作；该生产线建成后，将是目前国内规模最大、自动化程度最高的美缝剂生产线，整条产线由2条A组分生产线，12条B组分生产线组成。

The production line includes process design, equipmentmanufacture, steel structure construction, on-site installation, pipeline instrumentation system,andautomatic control system, etc. After the production line is completed, it will be the largest and most automatedgroutagent production line in China. The line consists of 2 A component production lines and 12 B component production lines.

系统特点：System characteristics

1、粉体投料系统无尘化、自动化，自带过滤滤芯及除尘系统，粉体补料过程中无粉尘飞扬；粉体根据配方需求全自动配料；极大的降低人工成本和改善工作环境；

The powder feeding system is dust-free and automatic, with its own filter element and dust removal system, and there is no dust flying in the process of powder feeding.The powder isfedautomatically according to the formulaand greatly reducinglabor costs and improvingthe working environment.

2、根据高粘度的物料特性，特殊设计混合搅拌结构，超高效混合，生产罐及调色罐真空设计压力为100pa；

According to the characteristics of high viscosity materials, the mixing structure is specially designed for ultra efficient mixing. The vacuum design pressure of production tank and color mixing tank is 100Pa.

3、B组分生产罐采用专色专罐，免清洗，无液废、固废；

The production tank of component Busesdifferenttanks for each color, which is free of cleaning and liquid&solid waste.

4、高效智能，自动化程度高，具备一键启动条件；液体配料及物料转移根据配方需求全自动运行；

High efficiency, high degree of automation, with one-key start condition.Liquid batching and materialconveyingare fully automaticoperatedaccording to formula.

5、成品采用恒压系统泵送至灌装机，这个输送过程全部在密闭的管道中进行，与全自动灌装机联动。

The finished product is pumped to the filling machine by a constant pressure system. This conveying process is all carried out in a closed pipeline, which is linked with the automatic filling machine.
