一． 设备简介

1、 Equipment introduction

      水性涂料是指用水作为溶剂或者分散剂的涂料，一般的的自来水或者井水是满足不了水性涂料生产的需求的，水质不好对产品质量性能影响很大，所以需要对原水进行处理成纯水的标准才能使用，从而产品质量性能得到提升，那么就需要工业纯水设备采用的是去离子水。JDB电子水务在满足用户用水标准的基础上，在设备系统中水箱均设有液位控制系统、水泵均设有压力保护装置、在线水质检测控制仪表、电气采用PLC可编程控制器，真正做到了无人职守，同时在工艺选材上采用推荐和客户要求的方法，使设备与其它同类产品相比较，具有更高的性价比和设备可靠性。

       Water based coating refers to the coating with water as solvent or dispersant. The general tap water or well water can not meet the needs of water-based coating production. The poor water quality has a great impact on the product quality and performance. Therefore, the raw water needs to be treated into pure water before it can be used, so the product quality and performance can be improved, Then, deionized water is needed for industrial pure water equipment. On the basis of meeting the user's water use standard, Hongjie water has set up liquid level control system in the water tank of the equipment system, pressure protection device in the water pump, online water quality detection and control instrument, and PLC programmable controller in the electrical system, so that no one is on duty. At the same time, the method of recommendation and customer requirements is adopted in the process of material selection, so that the equipment is compared with other similar products, It has higher cost performance and equipment reliability.
