據(jù)悉，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(gòu),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玉米淀粉餐具的生產(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。

It is reported that in the traditional process of making disposable corn starch tableware, the starch gelatinization process needs to use a variety of chemicals, which makes the operation more troublesome, inconvenient for process control and cost reduction, and the rework rate is high, and some raw materials are difficult to purchase. Therefore, the manufacturer has introduced a production method that can degrade disposable corn starch tableware, which is convenient for process control and operation, and can produce products with high qualification rate and low cost, And the products are easier to be 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)。

The process includes generalization of plant starch, feeding and mixing, expansion molding and surface treatment. Among them, the gelatinization temperature of plant starch is about 60-80 ℃, and the gelatinization time is 30-60 minutes. The weight percentage of each component of the material is plant starch 13-15, auxiliary agent 0,8-1.2, water allowance, and auxiliary agent is acrylic cationic material.

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 the traditional technology, the new disposable corn starch tableware production process mainly 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. As the chemical process is improved, only one chemical agent is selected, and the mixing degree and time of pulverization are reduced, the process is easy to control and 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 auxiliary agent used in the pasting process is commonly available, with low price and small dosage. This item can reduce the cost by 33% and reduce the total cost 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. As the UV curable resin is used for surface treatment of the product, the resin has strong water resistance, oil resistance and bacteria elimination effects, so the product qualification rate is high, 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, it is convenient for automatic continuous production and shortened processing time, so 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. Change rate of degradation quality>90%, 6-10% higher than 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(jiǎn)單、成本低、合格率高以及易降解等優(yōu)點(diǎn)。您有需求就來我們網(wǎng)站http://www.qylxschool.cn咨詢了解吧！
