PLA可降解片材生產線

　　PLA degradable sheet production line

　　PLA可降解片材生產線特點：螺桿采用漸變型單螺桿設計，針對聚乳酸，玉米淀粉熔融設計，同時針對材料的特殊性可開排氣，立三輥壓延成型，輥筒溫度通過模溫機可調出來的產品不糊料，產品成型表面色澤度好，韌性好，厚度采用千分表定位，收卷采用自動張力卷取。

　　Features: The screw adopts the gradient type single screw design, which is specially designed for the polylactic acid and corn starch melting. At the same time, it can be opened and vented according to the speciality of the material. The three-roll calendering is formed, and the temperature of the roller can be adjusted by the mold temperature machine. No paste, the product molding surface has good color, good toughness, the thickness is measured by the dial gauge, and the winding is automatically tensioned.

　　PLA可降解片材生產線工藝原理：PLA料玉米淀粉料→單螺桿擠出機：原料融熔塑化→ 快換過濾網→擠出模頭成型擠出 → 立三輥壓光機 → 冷卻定型裝置→ 切邊機構→牽引傳送→ 自動張力收卷

　　Process principle: PLA corn starch material → single screw extruder: raw material melt plasticization → quick change filter → extrusion die forming extrusion → vertical three roll calender → cooling setting device → trimming mechanism → traction Transfer → automatic tension winding
