In the traditional production of disposable corn starch tableware, many kinds of chemical additives are needed in the starch gelatinization process, which makes the operation troublesome, inconvenient for process control and cost reduction, and high rework rate, and some raw materials are not easy to purchase. Therefore, the manufacturer proposes a production method of degradable disposable starch tableware, which is convenient for process control and operation, and can produce high qualified rate and high cost Low cost products, and the products are more easily degraded and recycled after use.

該工藝包括植物淀粉概化、加料混勻、膨化成型和表面處理工藝。其中，植物淀粉糊化的工藝中糊化溫度是60-80℃、糊化時間是30-60分鐘，用料的各組分重量百分配比是植物淀粉13-15、助劑0，8-1.2、水余量、助劑是丙烯酸類陽離子的物質。

The process includes the generalization of plant starch, mixing, puffing and surface treatment. Among them, the gelatinization temperature of plant starch is 60-80 ℃, the gelatinization time is 30-60 minutes, the weight percentage ratio of each component is plant starch 13-15, adjuvant 0, 8-1.2, water surplus and auxiliary agent are acrylic cationic substances.

其中，表面處理為:影化成型的盤、碟類等產(chǎn)品可直接消菌即為成品;碗、盒類等產(chǎn)品，可先在其表面噴涂1-6UV克光固化樹脂，再經(jīng)紫外光發(fā)生器照射1-3秒，即為成品。

Among them, the surface treatment is as follows: the finished products can be directly sterilized by the shadow forming plate and dish; the products such as bowls and boxes can be sprayed with 1-6 UV gram UV curing resin on the surface, and then irradiated by the ultraviolet generator for 1-3 seconds.

與傳統(tǒng)技術相比，該新式一次性玉米淀粉餐具制作工藝主要有如下優(yōu)點：

Compared with the traditional technology, the new disposable corn starch tableware has the following advantages:

一是由于改進了化工藝，只是選用了一種化學助劑，并降低了粉化混度和時間，所以工藝易于控制操作也簡單。

One is that the process is easy to control and the operation is simple because only a chemical additive is selected and the pulverizing mixing degree and time are reduced.

二是糊化工藝中所用助劑普通易得，較低，用量少，此一項能減少成本33%，并使總成本降低8-10%。

Second, the additives used in the gelatinization process are common and easy to obtain, the price is low, and the dosage is small. This can reduce the cost by 33% and reduce the total cost by 8-10%.

三是由于采用了UV光固化樹脂對產(chǎn)品進行表面處理，該樹脂具有較強抵水、抗油和消菌作用，所以產(chǎn)品合格率高，可達90%。

Third, due to the use of UV curable resin for surface treatment of the product, the resin has strong water resistance, oil resistance and sterilization, so the product qualification rate is high, up to 90%.

四是由于抵水、抗油性能提高，便于自動化連續(xù)生產(chǎn)和縮短了加工時間，所以綜合能源成本可降低20左右。

Fourth, the comprehensive energy cost can be reduced by about 20 due to the improvement of water resistance and oil resistance, the convenience of automatic continuous production and the shortening of processing time.

五是降解質量變化率>90%，比同類產(chǎn)品提高6-10%

Fifth, the change rate of degradation quality is more than 90%, which is 6-10% higher than that of similar products

總之，該一次性玉米淀粉餐具新式生產(chǎn)法具有工藝易于控制、操作簡單、成本低、合格率高和易降解等優(yōu)點。

In a word, the new production method of disposable corn starch tableware has the advantages of easy control, simple operation, low cost, high qualified rate and easy degradation.
