**PET結(jié)晶除濕干燥系統(tǒng) / PET Crystallization Dehumidification and Drying System**
**概述 / Overview**
PET結(jié)晶除濕干燥系統(tǒng)是針對聚對苯二甲酸乙二醇酯(PET)原料特性開發(fā)的綜合性處理方案,集結(jié)晶化、深度除濕與高效干燥于一體。通過**控制溫度、濕度及物料停留時間,該系統(tǒng)可顯著提升PET顆粒的結(jié)晶度(≥45%),并將含水率降至≤30 ppm,徹底解決因吸濕性或結(jié)晶不足引發(fā)的加工缺陷(如水解降解、氣泡、霧化),廣泛應(yīng)用于食品包裝、紡織纖維、再生PET(rPET)加工等高精度制造領(lǐng)域。
*The PET Crystallization Dehumidification and Drying System is an integrated solution designed for polyethylene terephthalate (PET) materials, combining crystallization, deep dehumidification, and drying. By precisely controlling temperature, humidity, and material residence time, it enhances PET pellet crystallinity (≥45%) and reduces moisture to ≤30 ppm, eliminating processing defects (e.g., hydrolysis, bubbles, haze) caused by hygroscopicity or insufficient crystallization. It is widely used in food packaging, textiles, and rPET recycling for high-precision manufacturing.*
**核心功能與優(yōu)勢 / Core Features & Advantages**
1. **結(jié)晶-除濕協(xié)同工藝 / Synergized Crystallization & Dehumidification**
- **預結(jié)晶階段**: 梯度升溫(120-160°C)消除PET顆粒粘連,同步啟動結(jié)晶化(結(jié)晶度達30%-40%)。
