隨著人們對(duì)材料性能要求的不斷提高，可降解顆粒材料的潛在市場(chǎng)和主要需求增長(zhǎng)動(dòng)力。其中，生物降解的物理力學(xué)性能得到了很好的改善。為什么會(huì)說(shuō)生物降解顆粒作為良好的材料與基體樹(shù)脂密切相關(guān)？

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?

可生物降解的無(wú)機(jī)顆粒粒徑足夠小，顆粒之間的界面結(jié)合良好，無(wú)機(jī)顆粒像剛性鏈一樣在聚合物中起到增強(qiáng)作用，這種分散狀態(tài)有很好的效果。膠體二氧化硅和炭黑對(duì)橡膠有補(bǔ)強(qiáng)作用的重要原因之一是它們?cè)谙鹉z中形成了這種二聚結(jié)構(gòu)。

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(wú)機(jī)顆粒以隨機(jī)分散狀態(tài)存在，有的聚集成簇，有的以單獨(dú)的分散形式存在。這種分散狀態(tài)既不會(huì)增強(qiáng)也不會(huì)變韌。因?yàn)榉垠w中顆粒之間的相互作用很弱，會(huì)成為填充材料中較弱的環(huán)節(jié)。無(wú)機(jī)顆粒均勻且單獨(dú)地分散在基體樹(shù)脂中。

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.

在這種情況下，無(wú)論顆粒與基體樹(shù)脂之間是否存在良好的界面結(jié)合，都會(huì)產(chǎn)生一定的補(bǔ)強(qiáng)增韌效果。生物降解促進(jìn)了工程塑化的進(jìn)程，使其發(fā)揮著越來(lái)越重要的作用?？缮锝到忸w粒是具有改進(jìn)的阻燃性、強(qiáng)度、抗沖擊性、韌性等性能的塑料制品。

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，可降解成分或光敏劑（如淀粉）被添加到傳統(tǒng)塑料中，而不會(huì)影響其功能。在自然條件下，可生物降解的成分被降解，從而破壞了整個(gè)產(chǎn)品結(jié)構(gòu)，這不僅有利于減少塑料袋的“飛揚(yáng)”，也有利于加速耐火成分的降解。

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粒材料：淀粉基塑料。淀粉基塑料是我們生活中比較常見(jiàn)的可生物降解顆粒材料，比如一些一次性餐具。如果你有合適的工具，它的主要成分淀粉也可以在廚房里用淀粉制成。

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的聚合物。聚乳酸在整個(gè)生產(chǎn)過(guò)程中無(wú)污染，其性能與許多工程塑料相似，與有機(jī)物有良好的相容性。

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(guò)控制細(xì)菌種類和發(fā)酵過(guò)程來(lái)改變其組成。PHA可硬如工程塑料，也可軟如橡膠，成為近年來(lái)降解材料研究的熱點(diǎn)。

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.
