In order to prevent some polymers from hydrolyzing during processing due to high water content, they must be uniformly dried before processing to ensure the subsequent processing and the high quality of the product.
PET ）等需在一定环境（高真空度、特定温度、特定反应时间）下经固相缩聚来获得液相聚合无法得到的更高相对分子量。 In addition, some polymers, such as polyester ( PET ), need to undergo solid phase polycondensation in a certain environment (high vacuum, specific temperature, specific reaction time) to obtain higher relative molecular weights that cannot be obtained by liquid phase polymerization.
- 固相增黏一体机。 Based on full investigation and research, the company developed the DHDZF3 high-vacuum dynamic drying - solid phase thickening integrated machine specifically for the above needs . Compared with similar equipment on the market, this equipment has the following unique advantages:
1 ）在动态、高温（≤ 260 ℃）工况下，真空度可在 50 Pa~1000 Pa 间可调，并可在需要时长期保持高真空状态（≤ 50Pa ）； ( 1 ) Under dynamic and high temperature (≤ 260 ℃) working conditions, the vacuum degree can be adjusted between 50 Pa ~ 1000 Pa , and can maintain a high vacuum state (≤ 50Pa ) for a long time when needed ;
2 ）能在室温及较高使用温度（≤ 260 ℃）间，实现多阶段的程序控温及时间设定； ( 2 ) Able to realize multi-stage program temperature control and time setting between room temperature and higher use temperature (≤ 260 ℃);
3 ）本机料仓内设有四个带物料动态混合结构的料筒，当旋转时，该结构能有效提高聚合物干燥和固相增黏均匀性，有效防止高温下聚合物物料发生粘连，并且能用于两种或者两种以上不同聚合物的机械共混。 ( 3 ) There are four barrels with a material dynamic mixing structure in the silo of the machine. When rotating, this structure can effectively improve the uniformity of polymer drying and solid phase thickening, and effectively prevent polymer materials from blocking at high temperatures. , And can be used for mechanical blending of two or more different polymers.
4 ）真空控制系统中装有断电自动保护系统，在人工或者意外断电时，能立刻自动关闭料仓真空阀门，保护并维持料仓内的真空状态。 ( 4 ) The vacuum control system is equipped with a power failure automatic protection system. When the power is cut manually or accidentally, it can automatically close the vacuum valve of the silo immediately to protect and maintain the vacuum state in the silo.
