一次性玉米淀粉餐具在制作工艺上的优势

传统制作一次性玉米淀粉餐具的工艺中，淀粉糊化之工序需使用多种化学制剂，使得操作较为麻烦、不方便工艺的控制和减少成本,而且返工率高,有的原料不易采购,对此厂家推了一种便于工艺控制和操作的能降解一次性淀粉餐具的生产法,该方法能产出较高合格率和成本低的产品,且产品用后越易降解和回收。

In the traditional process of making disposable corn starch tableware, the starch gelatinization process requires the use of multiple chemical agents, which makes the operation more complicated, inconvenient for process control and cost reduction, and has a high rework rate. Some raw materials are not easy to purchase. Therefore, the manufacturer has proposed a production method that is easy to control and operate and can degrade disposable starch tableware. This method can produce products with high qualification rate and low cost, and the products are more easily degraded and recycled after use.

该工艺包括了植物淀粉概化、加料混匀、膨化成型以及表面的处理工艺。其中,植物淀粉糊化温度约为60-80℃、糊化时间是30-60分钟,用料的各组分重量百分配比是植物淀粉13-15、助剂0,8-1.2、水余量、助剂是丙烯酸类阳离子的物质。

This process includes the generalization of plant starch, mixing with ingredients, puffing and shaping, and surface treatment. Among them, the gelatinization temperature of plant starch is about 60-80 ℃, the gelatinization time is 30-60 minutes, and the weight percentage ratio of each component in the material is plant starch 13-15, additives 0,8-1.2, water residue, and additives are acrylic cationic substances.

其中,表面处理为:影化成型的盘、碟类等餐具产品可以直接消菌即成为成品;碗、盒类等产品,可先在其表面喷涂1-6UV克光固化树脂,再经紫外光发生器照射1-3秒,即为成品。

Among them, the surface treatment is that the plates, plates, and other tableware products formed by shading can be directly sterilized to become finished products; Bowls, boxes, and other products can be sprayed with 1-6 grams of UV cured resin on their surface, and then irradiated by a UV generator for 1-3 seconds to obtain the finished product.

与传统技术相比,该新式一次性玉米淀粉餐具制作工艺主要有如下优点：

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

1、由于改进了化工艺,只是选用了一种化学助剂,并降低了粉化混度和时间,所以工艺易于控制操作也简单。

1. Due to the improvement of the chemical process, only one chemical additive was selected, and the powder mixing and time were reduced, making the process easy to control and simple to operate.

2、糊化工艺中所用助剂普通易得,较低,用量少,此一项能减少成本33%,并使总成本降低8-10%。

2. The additives used in the gelatinization process are ordinary and easy to obtain, with lower prices and less dosage. This can reduce costs by 33% and reduce total costs by 8-10%.

3、由于采用了UV光固化树脂对产品进行表面处理,该树脂具有较强抵水、抗油和消菌作用,所以产品合格率高,可达90%。

3. Due to the use of UV curable resin for surface treatment of the product, this resin has strong water resistance, oil resistance, and antibacterial properties, resulting in a high product qualification rate of up to 90%.

4、由于抵水、抗油性能提高,便于自动化连续生产和缩短了加工时间,所以综合能源成本可降低20左右。

4. Due to the improved water resistance and oil resistance, which facilitate automated continuous production and shorten processing time, the comprehensive energy cost can be reduced by about 20%.

5、降解质量变化率>90%,比同类产品提高6-10%

5. Degradation quality change rate>90%, 6-10% higher than similar products
