傳統(tǒng)制作一次性玉米淀粉餐具的工藝中，淀粉糊化之工序需使用多種化學(xué)制劑，使得操作較為麻煩、不方便工藝的控制和減少成本,而且返工率高,有的原料不易采購,對(duì)此廠家推了一種便于工藝控制和操作的能降解一次性淀粉餐具的生產(chǎn)法,該方法能產(chǎn)出較高合格率和成本低的產(chǎn)品,且產(chǎn)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.

該工藝包括了植物淀粉概化、加料混勻、膨化成型以及表面的處理工藝。其中,植物淀粉糊化溫度約為60-80℃、糊化時(shí)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(zhì)。

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,表面處理為:影化成型的盤、碟類等餐具產(chǎn)品可以直接消菌即成為成品;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 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.

與傳統(tǒng)技術(shù)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(diǎn)：

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

1、由于改進(jìn)了化工藝,只是選用了一種化學(xué)助劑,并降低了粉化混度和時(shí)間,所以工藝易于控制操作也簡(jiǎn)單。

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、糊化工藝中所用助劑普通易得,較低,用量少,此一項(xiàng)能減少成本33%,并使總成本降低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光固化樹脂對(duì)產(chǎn)品進(jìn)行表面處理,該樹脂具有較強(qiáng)抵水、抗油和消菌作用,所以產(chǎn)品合格率高,可達(dá)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,便于自動(dòng)化連續(xù)生產(chǎn)和縮短了加工時(shí)間,所以綜合能源成本可降低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、降解質(zhì)量變化率>90%,比同類產(chǎn)品提高6-10%

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