a. Visual observation, that is, starch products are sub light type, some light yellow or milky white. The color of non starch products is dark or bluish white.

b.氣味辯別即同類產品相互摩擦產生熱量后淀粉類產品有淡淡玉米糊味或植物香味其它類產品有塑料氣味。

b. Odor discrimination means that starch products have light corn paste flavor or plant flavor after heat generated by friction between similar products, and other products have plastic smell.

c.燃燒辯別即二類產品分別燃燒紅火焰為淀粉類藍火焰為其它類,燃燒后的灰份用手碾碎后黑色粉沫為淀粉類產品而粉沫較為淺色的是其它類產品。

c. Combustion discrimination means that the red flame is starch and the blue flame is the other. The black powder after burning ash is crushed by hand is starch product, while the powder foam is light color is other products.

2、主要成份有載體樹脂.玉米淀粉.偶聯(lián)劑浸潤劑相溶劑等低分子,構成。

2. The main components are carrier resin, corn starch, coupling agent, wetting agent, solvent, etc.

3、漂浮物可能有二種情況造成的

3. There are two possible causes of floating debris

a.潤滑劑添加量過大并在加工過程中沒有完全脫揮使殘渣付于產品表面上造成的。

a. It is caused by excessive addition of lubricant and incomplete devolatilization in the process of processing, which makes the residue on the surface of the product.

b.無機物如滑石粉.重質鈣添加量過大而形成的。

b. Inorganic substances such as talcum powder. Formed by adding too much heavy calcium.

編輯本段產品優(yōu)點一次性可降解餐具的優(yōu)點：

Advantages of disposable degradable tableware

無公害：由于它是玉米淀粉和其他環(huán)保材料精制而成，不含對人體有害的物質，可放心長期使用。

Pollution free: because it is refined from corn starch and other environmental protection materials, it does not contain substances harmful to human body, so it can be used for a long time.

零污染：產品埋入泥土中，在適宜的溫度下，90天后可降解形成二氧化碳和水，對土壤和空氣不造成污染。

Zero pollution: the product is buried in the soil and can be degraded to form carbon dioxide and water after 90 days under the appropriate temperature, which does not cause pollution to the soil and air.

省資源：玉米淀粉是可再生資源，取之不盡，用之不竭，而紙質餐具和塑料餐具需大量的木材和石油化工產品。以玉米淀粉為原料可節(jié)省大量的石油和森林資源。

Provincial resources: corn starch is a renewable resource, inexhaustible, and paper tableware and plastic tableware need a lot of wood and petrochemical products. Corn starch can save a lot of oil and forest resources.

高品質：產品密織性好，耐水、耐油、防滲透，同時具有良好的耐高溫和耐低溫性，適合冰箱冷凍、冷藏、保鮮食品，微波爐加熱等。

High quality: the product has good tightness, water resistance, oil resistance, impermeability, high temperature resistance and low temperature resistance. It is suitable for refrigerators to freeze, refrigerate, keep fresh food and microwave oven heating.

編輯本段產品前景一次性餐具自1984年在我國使用以來，一聚苯乙烯（eps)為主要原料的發(fā)泡塑料餐具迅速遍布我國的每個角落，進路人的日常生活，形成巨大的消費市場。據統(tǒng)計，目前我國每年消費快餐用具約100億只，其中大部分是一次性發(fā)泡塑料餐具，并且每年以25%的速度增長。由于聚苯乙烯的不可降解，難以回收等缺點，給處理工作帶來了很大的不便。目前在我國個城市的大街小巷，旅游景點、鐵路沿線及江河湖泊。這種被廢棄的一次性餐具隨處可見，可謂觸目驚心，給環(huán)境造成了嚴重的污染。這種“白色污染”不僅增加了環(huán)衛(wèi)工人的勞動強度，給人們帶來視覺上的污染，而且正日益嚴重的污染著我們賴以生存的土地資源和水資源，同樣給人們帶來了諸多的不便和危害。令人欣慰的是我國在這方面的研究已經做了大量的工作，并且取得了很大的成績，加上在政府的科學指導和強有力的支持下，各種環(huán)境餐具便應運而生，收到良好的社會效果。

Since 1984, polystyrene tableware has been widely used in China for the first time in the market. According to statistics, China consumes about 10 billion fast food utensils every year, most of which are disposable foam plastic tableware, and the annual growth rate is 25%. Because polystyrene is non degradable and difficult to recover, it brings great inconvenience to the treatment. At present, in the streets and alleys of cities, tourist attractions, along the railway and rivers and lakes. This kind of disposable tableware can be seen everywhere, which has caused serious pollution to the environment. This kind of "white pollution" not only increases the labor intensity of sanitation workers, but also pollutes the land resources and water resources that we rely on for existence, and also brings a lot of inconvenience and harm to people. It is gratifying that China has done a lot of work in this field, and has made great achievements. With the scientific guidance and strong support of the government, various environmental tableware came into being and received good social effects.
