1)分辨很簡(jiǎn)單,可分為三個(gè)方面:

1) The discrimination is very simple and can be divided into three aspects:
a.視覺(jué)觀察即淀粉類(lèi)餐具為亞光型產(chǎn)品有些淡黃或乳白色。而非淀粉類(lèi)產(chǎn)品色澤暗黑或青白色。
a. Visual observation indicates that starch tableware is a matte product with some light yellow or milky white color. Non starch products have a dark or bluish white color.
b.氣味辯別即同類(lèi)產(chǎn)品相互摩擦產(chǎn)生熱量后淀粉類(lèi)產(chǎn)品有淡淡玉米糊味或植物香味其它類(lèi)產(chǎn)品有塑料氣味 。
b. Odor discrimination refers to the process of similar products rubbing against each other to generate heat. Starch products have a light corn paste flavor or a plant aroma, and other products have a plastic odor.
c.燃燒辯別即二類(lèi)產(chǎn)品分別燃燒紅火焰為淀粉類(lèi)藍(lán)火焰為其它類(lèi),燃燒后的灰粉用手碾碎后黑色粉沫為淀 粉類(lèi)產(chǎn)品而粉沫較為淺色的是其它類(lèi)產(chǎn)品。
c. Combustion discrimination refers to the two types of products that burn red flames for starch and blue flames for other types. The burnt gray powder is crushed by hand and the black powder is turned into starch products, while the lighter colored powder is turned into other types of products.
2)、主要成份有載體樹(shù)脂。玉米淀粉。偶聯(lián)劑浸潤(rùn)劑相溶劑等低分子,構(gòu)成。
2) The main component is carrier resin. Corn starch. Low molecular weight, such as 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
一次性玉米淀粉餐具
a.潤(rùn)滑劑添加量過(guò)大并在加工過(guò)程中沒(méi)有完全脫揮使殘?jiān)队诋a(chǎn)品表面上造成的。
a. Excessive lubricant addition and incomplete devolatilization during the processing result in residue being deposited on the surface of the product.
b.無(wú)機(jī)物如滑石粉。重質(zhì)鈣添加量過(guò)大而形成的。
b. Inorganic substances such as talc powder. Formed by excessive addition of heavy calcium.
玉米淀粉一次性餐具現(xiàn)狀:用玉米淀粉餐具的不多
Current Situation of Disposable Corn Starch Tableware: Not Many Use Corn Starch Tableware
玉米淀粉餐具成本就是高,因?yàn)樵腺F。不說(shuō)成本,就說(shuō)批發(fā)價(jià),塑料餐具一般是2毛,而玉米淀粉的到了6毛5,這是行情。生產(chǎn)的技術(shù)和流程上都差不多,主要還是因 為玉米淀粉的原料貴。玉米淀粉餐具里的玉米淀粉含量要保證。
The cost of corn starch tableware is high because the raw materials are expensive. Not only the cost, but also the wholesale price. Plastic tableware is usually priced at 20 cents, while corn starch is priced at 65 cents, which is the market trend. The production technology and process are similar, mainly because the raw material of corn starch is expensive. The corn starch content in corn starch tableware should be ensured.
