可降解塑料顆粒制造過程詳解

　　Detailed explanation of the manufacturing process of biodegradable plastic particles

　　一、可降解塑料的制造原料

　　1、 Raw materials for manufacturing biodegradable plastics

　　可降解塑料的制造原料主要有玉米淀粉、木質素、聚乳酸等，它們的特點是生物可降解，對環境影響小。

　　The main raw materials for manufacturing biodegradable plastics include corn starch, lignin, polylactic acid, etc. Their characteristics are biodegradability and minimal environmental impact.

　　二、可降解塑料顆粒制造工藝流程

　　2、 Manufacturing process flow of biodegradable plastic particles

　　可降解塑料顆粒制造的工藝流程包括物料預處理、混合擠出和顆粒成型三個階段。

　　The manufacturing process of biodegradable plastic particles includes three stages: material pretreatment, mixed extrusion, and particle forming.

　　1. 物料預處理

　　1. Material pretreatment

　　物料預處理主要是將原料進行加工和處理，包括混合、除雜、干燥等過程，以保證塑料顆粒的質量和均勻度。

　　Material pretreatment mainly involves processing and processing raw materials, including mixing, impurity removal, drying, etc., to ensure the quality and uniformity of plastic particles.

　　2. 混合擠出

　　2. Mixed extrusion

　　在混合擠出階段，將經過預處理的原料加入到擠出機中進行熔融和混合。熔融和混合的目的是使原料均勻地分布在整個擠出機內。同時，通過改變擠出機壁內部的壓力來控制擠出機的出料速度和顆粒的大小。

　　In the mixed extrusion stage, the pre treated raw materials are added to the extruder for melting and mixing. The purpose of melting and mixing is to evenly distribute the raw materials throughout the entire extruder. At the same time, the discharge speed and particle size of the extruder are controlled by changing the pressure inside the extruder wall.

　　3. 顆粒成型

　　3. Particle forming

　　顆粒成型階段是將熔融和混合后的原料經過冷卻、切割和包裝等步驟變成顆粒狀態。這些顆粒可以直接用于生產可降解塑料制品。

　　The particle forming stage is the process of cooling, cutting, and packaging the melted and mixed raw materials into a granular state. These particles can be directly used to produce biodegradable plastic products.

　　三、可降解塑料在環保領域的應用前景

　　3、 The application prospects of biodegradable plastics in the field of environmental protection

　　隨著環保意識的逐漸提高，可降解塑料的應用前景越來越廣闊。它們可以應用于各個領域，如包裝、農業、餐飲、醫療等。與傳統塑料相比，可降解塑料不會對環境造成負面影響，符合現代社會的可持續發展理念。

　　With the gradual improvement of environmental awareness, the application prospects of biodegradable plastics are becoming increasingly broad. They can be applied in various fields, such as packaging, agriculture, catering, healthcare, etc. Compared with traditional plastics, biodegradable plastics do not have negative impacts on the environment and are in line with the sustainable development concept of modern society.

　　總之，可降解塑料的制造工藝流程和原料選取對于制造可降解塑料顆粒具有重要意義。相信未來在可降解塑料的廣泛應用下，環保事業將會取得更加顯著的成果。

　　In summary, the manufacturing process and selection of raw materials for biodegradable plastics are of great significance for producing high-quality biodegradable plastic particles. I believe that with the widespread application of degradable plastics in the future, the environmental protection industry will achieve more significant results.
