實（shí）用美（měi）觀玉米澱粉顆粒製作產品優勢

As amylose increases, the average particle size and crystallinity of corn starch particles gradually decrease, and the degree of polarization cross will also weaken. According to the degree of clarity and crystallinity of the polarized cross, the order is: waxy corn starch>regular corn starch>high amylose corn starch. The observation results using a scanning electron microscope show that waxy corn starch is mostly irregularly polygonal in shape; However, ordinary corn starch is similar to waxy corn starch, with most being irregularly polygonal and a few being spherical. And the particle diameter of high amylose corn starch is smaller than that of waxy corn starch and regular corn starch.

利用光學顯微（wēi）鏡觀察三種不同直鏈澱粉含量（liàng）玉米澱粉結構發現，以顆粒大小（xiǎo）和均勻程度而言，26% 普通玉米澱（diàn）粉＞50% 高直鏈玉米澱（diàn）粉＞70% 高直鏈玉米澱粉。且26% 普通玉米澱（diàn）粉顆粒形貌近似圓（yuán）形（xíng），而 50% 和（hé） 70% 高直（zhí）鏈玉米澱粉顆粒形貌都近（jìn）似橢圓形。通過（guò）掃描電子顯微鏡（SEM）觀察，也證實高直鏈玉（yù）米澱粉大多（duō）數為橢圓（yuán）形，少數為不規則形狀（zhuàng）。高衛帥等對高直鏈玉米澱粉蠟質玉米澱粉和（hé）普通（tōng）玉米澱粉進行粒度分布實驗。

Observing the structure of corn starch with three different levels of amylose content using an optical microscope, it was found that in terms of particle size and uniformity, 26% ordinary corn starch>50% high amylose corn starch>70% high amylose corn starch. And the morphology of 26% ordinary corn starch particles is approximately circular, while the morphology of 50% and 70% high amylose corn starch particles are approximately elliptical. Through scanning electron microscopy (SEM) observation, it was also confirmed that most of the high amylose corn starch is elliptical in shape and a few are irregular in shape. Gao Weishuai et al. conducted particle size distribution experiments on high amylose corn starch, waxy corn starch, and ordinary corn starch.

通過分析粒度分布圖（tú）表明，普通玉米澱粉和蠟（là）質玉米澱（diàn）粉粒度分布情況（包（bāo）括：徑距比（bǐ）表麵積表麵積平均粒徑體積平均粒度等）基本（běn）相同，粒徑值與更小（xiǎo）值（zhí）差距較（jiào）小；而高直鏈（liàn）玉米澱粉上述參數比另外兩種玉米澱粉（fěn）大，且粒徑值與更小值差距也較大，粒徑分布相對較均勻。

By analyzing the particle size distribution diagram, it is shown that the particle size distribution of ordinary corn starch and waxy corn starch (including the average particle size, volume, particle size, etc.) is basically the same, and the difference between particle size values and smaller values is relatively small; The above parameters of high amylose corn starch are larger than the other two types of corn starch, and the difference between the particle size value and the smaller value is also significant, and the particle size distribution is relatively uniform.

無定型區和結晶區通過環狀交替（tì）形成（chéng）澱粉顆粒。其主要構成是由直鏈澱粉和支鏈澱粉組成，結（jié）晶（jīng）區主要有支鏈澱粉組成，也含有少量直鏈澱粉（直鏈澱粉含量儀）；大部分直鏈澱粉形成無定形區。

The amorphous and crystalline regions alternate in a circular pattern to form starch particles. Its main composition is composed of amylose and amylopectin, and the crystallization zone mainly consists of amylopectin, which also contains a small amount of amylose (amylose content meter); Most amylose forms amorphous regions.

結晶區和無定形區折射率和密度不同，從而在偏光顯微鏡下觀察澱粉顆粒時會產生偏光十字。不同種類（lèi）玉米澱（diàn）粉偏光十字位置性狀及明顯程度都有差異（yì），偏光十（shí）字（zì）明（míng）顯程度受（shòu）澱粉顆粒大小和（hé）結晶程度影響。直鏈澱粉（fěn）含量影（yǐng）響澱粉結晶程度，直鏈澱粉含量越高，結晶度越低。

The refractive index and density of the crystalline and amorphous regions are different, resulting in a polarized cross when observing starch particles under a polarizing microscope. There are differences in the position and degree of polarization cross of different types of corn starch, and the degree of polarization cross is influenced by the size and crystallinity of starch particles. The content of amylose affects the degree of starch crystallization, and the higher the content of amylose, the lower the degree of crystallinity.

隨著塑料餐具（jù）較多使用，消費者的需求也不僅僅（jǐn）停留在簡單的能用就可以了，很多（duō）消費者對產品的（de）各個方麵也（yě）有了對（duì）應的要求（qiú），塑料餐具廠家也為了迎合消費者的需求進行了一些列的設計和生產，下麵就簡（jiǎn）單介紹一下要求（qiú）：

With the increasing use of plastic tableware, consumers' needs are not limited to simple functionality. Many consumers also have corresponding requirements for various aspects of the product. Plastic tableware manufacturers have also carried out a series of design and production to meet the needs of consumers. Below is a brief introduction to the requirements:

耐磨性

Wear resistance

具備反（fǎn）複使（shǐ）用方便，隨著環保意識的增加塑料袋再次利用也成了很（hěn）多消費者的習慣（guàn），所以就要（yào）具備較好的耐磨性

With the increasing awareness of environmental protection, the reuse of plastic bags has become a habit for many consumers, so it is necessary to have good wear resistance

印刷圖案

Printing patterns

普通市場的方便袋對印刷設計沒有太多要求，但是一些包裝袋就有要（yào）求了，好看的設計圖案在視覺上給消（xiāo）費者較好的吸（xī）引，也利於產品的銷售，這一方麵的作用越來越大了。

The convenience bags in the ordinary market do not have many requirements for printing design, but some packaging bags do. Beautiful design patterns visually attract consumers and are also conducive to product sales, which plays an increasingly important role.

密封性

Sealing performance

不同的貨物包裝，對於密封程度也有不同的要求。然（rán）而，在（zài）正常情況下，需要密封的產品通常具有潮濕和發黴的特（tè）性。因此，大多數工業對（duì）包裝袋的密（mì）封性能要求一般都很（hěn）高。

Different packaging of goods also have different requirements for the degree of sealing. However, under normal circumstances, products that need to be sealed usually have damp and moldy characteristics. Therefore, most industries generally have high requirements for the sealing performance of packaging bags.

實用性

Practicality

包裝袋的設計和生產，塑料袋生產商具體的方式提醒客戶使用的考（kǎo）慮，如環境（jìng），使（shǐ）用商業物業運輸儲存環境。

The design and production of packaging bags, as well as the specific ways for plastic bag manufacturers to remind customers of their usage considerations, such as the environment and the use of commercial property transportation and storage environments.

保存性（xìng）

Preservation

根據用戶不同的商（shāng）品（pǐn）條件，選擇適合的材料和合理（lǐ）的比例，設計製作適合不同行業的塑料袋（dài）。例如，有些塑料製品害怕（pà）長時間的直射陽光，這對產品的保存有不好的影響（xiǎng）。行業可以在這方麵改進和發展。

According to the different product conditions of users, choose suitable materials and reasonable proportions to design and produce plastic bags suitable for different industries. For example, some plastic products are afraid of prolonged direct sunlight, which has a negative impact on product preservation. The industry can improve and develop in this area.

玉米澱粉塑料製品（pǐn）具有生物可降解性良好機械性能及物理性能良好相容性良好（hǎo）的優點。但與易得的甘蔗漿相比，玉米聚乳酸產量仍不高。而且玉米也是一種主糧，大量製作聚（jù）乳酸會大量消耗玉米（mǐ），從而提高糧食的。

Corn starch plastic products have the advantages of good biodegradability, mechanical properties, and physical properties, as well as good compatibility. However, compared to easily available sugarcane syrup, the yield of corn polylactic acid is still not high. Moreover, corn is also a staple food, and large-scale production of polylactic acid will consume a large amount of corn, thereby increasing the price of food.
