一次性環(huán)保餐具因使用方便而受到了人們的喜愛,日常生活隨處可見。目前市場上的一次性快餐盒大多是由石油中提煉的聚苯乙烯原料加上發(fā)泡劑,加熱發(fā)泡而成。聚苯乙烯是一種使用為廣泛的高分子材料,具有毒性較低、熔點較高、可塑性強、生產(chǎn)簡便等特點,因而成了制一次性快餐盒的材料。一次性環(huán)保餐具的四種材料類型:
Disposable environment-friendly tableware is loved by people because of its convenient use and can be seen everywhere in daily life. At present, most of the disposable fast-food boxes in the market are made of polystyrene raw materials extracted from petroleum and foaming agents, which are heated and foamed. Polystyrene is a widely used polymer material, which has the characteristics of low toxicity, high melting point, strong plasticity and simple production, so it has become the first choice for making disposable fast food boxes. Four material types of disposable environmental friendly tableware:
1、紙板型紙板快餐盒是以300-350克的漂白硫酸鹽木漿紙板為原料,通過類似鈑加工的沖壓成型工藝進行模切黏合或模切壓制、定型等工序制成。為防止其滲油或滲水,要在其表面淋膜或施用化學助劑。在生產(chǎn)與使用過程中對人體是、無副作用的。但對于紙板的質(zhì)量要求較高,隨之成本也提高。
1. The paperboard fast-food box is made of 300-350g bleached kraft wood pulp paperboard by die-cutting bonding or die-cutting pressing, shaping and other processes through a stamping process similar to sheet metal processing. In order to prevent oil or water seepage, film or apply chemical additives on the surface. In the process of production and use, it is non-toxic and has no side effects. However, the quality of paperboard is required to be high, and the cost is also increased.
2、淀粉型以淀粉為原料的可食用型快餐盒,顧名思義,它是以淀粉類植物為原料,加入膳食纖維和其他可食用類助劑經(jīng)攪拌捏合而成,它采用生物復配、聚糖交聯(lián)、鈣離子螯合等技術(shù)精制而成,有致密層、內(nèi)防水層、膠網(wǎng)層和外防水層四部分構(gòu)成。
2. Starch type edible fast food box with starch as raw material, as the name implies, is made of starch plants as raw materials, dietary fiber and other edible additives through mixing and kneading. It is refined by biological compounding, glycan crosslinking, calcium ion chelation and other technologies, and consists of four parts: dense layer, inner waterproof layer, rubber net layer and outer waterproof layer.

3、紙漿模塑型木紙漿或蘆葦、蔗渣、麥秸、稻草等一年生草本植物纖維紙漿經(jīng)碎漿和凈化,加入適量化學助劑,成型、干燥、整型、定型、切邊、制成。產(chǎn)品的美觀性并不高,同時也會增加廢水的污染。
3. Pulp molded wood pulp or annual herb fiber pulp such as reed, bagasse, wheat straw and rice straw is made by pulping and purification, adding an appropriate amount of non-toxic chemical additives, molding, drying, shaping, shaping, trimming and disinfection. The beauty of the product is not high, and it will also increase the pollution of waste water.
4、植物纖維型在環(huán)保優(yōu)勢上,植物纖維餐盒具有明顯的優(yōu)勢,它是以稻草、稻谷殼、甘蔗渣等提取的植物纖維作為原料,加入成型劑、黏合劑、耐水劑等助劑攪拌通過成型機成型,加以干燥、整形、等后期加工而成。這些農(nóng)業(yè)的下腳料可成為工業(yè)原料,有助于農(nóng)業(yè)資源的綜合利用。
4. Plant fiber type has obvious advantages in environmental protection. It is made of plant fiber extracted from rice straw, rice husk and bagasse as raw materials, mixed with molding agent, adhesive, water-resistant agent and other additives, formed by molding machine, dried, shaped and disinfected. These agricultural leftovers can become industrial raw materials and contribute to the comprehensive utilization of agricultural resources.
在自然環(huán)境中,經(jīng)過一段時間,一次性環(huán)保餐具是可以自己降解的,那么這也就解決的不可降解餐具對環(huán)境的危害問題。并且也節(jié)省了不可降解餐具的主要原料石油等資源。您有更多問題就來我們網(wǎng)站http://咨詢了解吧。
In the natural environment, after a period of time, disposable environmental friendly tableware can be degraded by itself, so this also solves the problem of environmental damage caused by non degradable tableware. And it also saves non renewable resources such as petroleum, the main raw material of non degradable tableware. If you have more questions, please come to our website http:// Consult and understand.
