配方設(shè)計

Formulation design

餐具所使用的填料為秸稈粉，如小麥秸稈粉、玉米秸稈粉或油菜秸稈粉等。

The filler used in tableware is straw powder, such as wheat straw powder, corn straw powder or rape straw powder.

黏合劑為PLA和淀粉混合物，兩者質(zhì)量比優(yōu)選為( 10 ～ 15) ∶ ( 20 ～ 25) 。

The adhesive is a mixture of PLA and starch, and the mass ratio of PLA and starch is (10-15) ∶ (20-25).

填充劑為色白、環(huán)保且成本較低的滑石粉，助劑優(yōu)選用KH-550w 型硅烷偶聯(lián)劑。

The filling agent is talc powder with white color, safety and environmental protection and low cost, and kh-550w silane coupling agent is preferred as auxiliary agent.

工藝步驟

Process steps

該秸稈餐具的加工主要采用一次熱壓成型的方法，包括如下步驟:

The straw tableware is mainly processed by one-step hot pressing method, including the following steps:

步驟一：將秸稈粉、黏合劑、填充劑、助劑和水混合并以40W攪拌電機攪拌1kg物料為例，在攪拌20～30min后，再以噴霧形式加入助劑和水攪拌15～20min，得到混合料。

Step one: mix straw powder, binder, filler, additives and water, and stir the 1kg material with 40W stirring motor as an example. After mixing 20 to 30min, add the assistant and water 15 to 20min in spray form, and get the mixture.

步驟二：將得到的混合料放入模具中進行熱壓成型，熱壓成型的具體條件為：180～200℃恒溫中在30～40的壓力下保壓30～50s，即得到秸稈餐具。

Step 2: put the mixture into the mold for hot pressing, and the specific conditions of hot pressing are as follows: the straw tableware is obtained by holding the mixture at 180-200 ℃ for 30-50s under the pressure of 30-40.

結(jié)論

conclusion

經(jīng)一次熱壓成型得到的餐具產(chǎn)品原料低廉，餐具整體可自行降解為有機肥料，且降解速度快，無害，環(huán)保。

The raw materials of tableware products obtained by one-step hot pressing are low, and the tableware can be degraded into organic fertilizer by itself with fast degradation speed, non-toxic and harmless, safety and environmental protection.

一次熱壓成型比常壓成型得到的產(chǎn)品強度更高，工藝簡單，可操作性高，易于推廣；并且可方便得到不同尺寸、形狀和厚度的餐具。

Compared with normal pressure molding, one-time hot pressing molding has higher strength, simple process, high operability, easy to promote, and can easily get different sizes, shapes and thicknesses of tableware.

根據(jù)模具的不同，采用該研究所述方法可制備各種尺寸和形狀的餐具或器皿，比如盤子、碗、筷、勺子、餐盒、育苗盒等。

According to different molds, tableware or utensils of various sizes and shapes can be prepared by the method described in this study, such as plates, bowls, chopsticks, spoons, lunch boxes, seedling boxes, etc.

秸稈/聚乳酸復(fù)合材料是一種新型降解材料，建議加大對此材料的研究和開發(fā)應(yīng)用力度，為環(huán)保做更大的貢獻。

Straw / PLA composite is a new type of degradation material. It is suggested that the research and development of this material should be strengthened to make greater contribution to environmental protection.
