生物降解顆粒作為良（liáng）好的材料（liào）與基體樹脂（zhī）密切相關！

隨著人們對材料（liào）性能要求的不斷提高，可降（jiàng）解顆粒材料的（de）潛在市場和主要需求增長動力。其中，生物降解的物理力學性能得到了很好的改（gǎi）善。為什麽會說生物降解顆粒作（zuò）為良好（hǎo）的材（cái）料（liào）與基體樹脂密切相關？

With the continuous improvement of people's requirements for material properties, the potential market and main demand growth power of degradable granular materials. Among them, the physical and mechanical properties of biodegradation have been well improved. Why is it said that biodegradable particles are closely related to matrix resin as a good material?

可生（shēng）物降解的無機顆（kē）粒粒徑足夠小，顆（kē）粒之間的界麵結合良好，無（wú）機顆粒像剛性（xìng）鏈一樣在聚合物中起到增強（qiáng）作用，這種分散狀態有（yǒu）很好的效果。膠體二氧化矽和炭黑對橡膠（jiāo）有補強作用的重要原因之一是（shì）它們在橡膠中形成了這種二聚結構。

The particle size of biodegradable inorganic particles is small enough, and the interface between particles is well combined. Inorganic particles play a reinforcing role in polymers like rigid chains. This dispersion state has a good effect. One of the important reasons why colloidal silica and carbon black have reinforcing effect on rubber is that they form this dimer structure in rubber.

無機（jī）顆粒以隨機分散狀態存在，有的聚集成簇，有的以單獨的分散形式存在。這種分散狀態既不會增強也不會變韌（rèn）。因為粉（fěn）體中顆粒之間的相互作用很弱，會成（chéng）為填充材料（liào）中較弱的環節。無機顆（kē）粒均勻且單獨地分（fèn）散在（zài）基體樹脂（zhī）中。

Inorganic particles exist in a random dispersion state, some are clustered, and some exist in a separate dispersion form. This dispersion will neither strengthen nor toughen. Because the interaction between particles in the powder is very weak, it will become a weak link in the filling material. The inorganic particles are uniformly and separately dispersed in the matrix resin.

在這種情（qíng）況下，無論顆粒與基體樹脂（zhī）之間是否存在（zài）良好的界麵結合，都（dōu）會產生（shēng）一定的補強增韌效果。生物降解促進了工（gōng）程塑化的進程，使其發揮（huī）著越來越重要的作用。可生物降解顆粒是具有改進的阻燃（rán）性、強度、抗衝擊性、韌性等性（xìng）能的塑料製品。

In this case, whether there is a good interface between particles and matrix resin or not, it will produce a certain reinforcement and toughening effect. Biodegradation promotes the process of Engineering plasticization, making it play a more and more important role. Biodegradable particles are plastic products with improved flame retardancy, strength, impact resistance and toughness.

早期，可降解成分（fèn）或光敏劑（如澱粉）被添加到傳統塑料中，而不會影響（xiǎng）其功能。在自然條件下，可生物降解（jiě）的成分被降解，從而破壞（huài）了整個產品（pǐn）結構，這不僅有利於減少塑料袋的“飛揚”，也有利於加速耐火成（chéng）分的降解。

In the early stage, degradable components or photosensitizers (such as starch) were added to traditional plastics without affecting their function. Under natural conditions, biodegradable components are degraded first, thus damaging the whole product structure, which is not only conducive to reducing the "flying" of plastic bags, but also conducive to accelerating the degradation of refractory components.

日常生活中遇到的可生物降解顆（kē）粒材料：澱（diàn）粉基塑料（liào）。澱粉基塑料是我們生活中比較（jiào）常見（jiàn）的可生物降解顆粒材料，比如一些一次性餐具。如果你有（yǒu）合適的工具，它的主要成分澱粉也可（kě）以在廚房裏用澱（diàn）粉製成。

Biodegradable materials encountered in daily life: starch based plastics. Starch based plastic is a common biodegradable granular material in our life, such as some disposable tableware. If you have the right tool, its main component starch can also be made of starch in the kitchen.

聚乳酸（PLA）。聚乳酸是乳酸中的羥基和羧基脫水形成（chéng）的聚合物。聚乳酸在整個生產過程中無汙染，其性能與許多工程塑料相似，與有機物有良好的（de）相容性。

Polylactic acid (PLA). Polylactic acid is a polymer formed by dehydration of hydroxyl and carboxyl groups in lactic acid. Polylactic acid is pollution-free in the whole production process. Its properties are similar to many engineering plastics and have good compatibility with organics.

聚羥基鏈烷酸酯(PHA)。PHA可以通過控製細菌種（zhǒng）類（lèi）和發酵過程來改變其組成。PHA可硬如工程塑料，也可（kě）軟如橡（xiàng）膠，成為近年來降解材料研究（jiū）的熱點。

Polyhydroxyalkanoates (PHA). PHA can change its composition by controlling bacterial species and fermentation process. PHA can be as hard as engineering plastics or as soft as rubber, which has become a research hotspot of degradable materials in recent years.

這（zhè）裏解釋了作為良好材料的可生物降解（jiě）顆粒與基（jī）體樹脂之間的密切關係的內容。如果（guǒ）您想（xiǎng）了解更多，請關注我們的（de）網站www.shuiniguan.com！
