一次性环保餐具因使用方便而受到了人们的喜爱,日常生活随处可见。目前市场上的一次性快餐盒大多是由石油中提炼的聚苯乙烯原料加上发泡剂,加热发泡而成。聚苯乙烯是一种使用为广泛的高分子材料,具有毒性较低、熔点较高、可塑性强、生产简便等特点,因而成了制一次性快餐盒的材料。一次性环保餐具的四种材料类型:
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、纸板型纸板快餐盒是以300-350克的漂白硫酸盐木浆纸板为原料,通过类似钣加工的冲压成型工艺进行模切黏合或模切压制、定型等工序制成。为防止其渗油或渗水,要在其表面淋膜或施用化学助剂。在生产与使用过程中对人体是无毒、无副作用的。但对于纸板的质量要求较高,随之成本也提高。
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、淀粉型以淀粉为原料的可食用型快餐盒,顾名思义,它是以淀粉类植物为原料,加入膳食纤维和其他可食用类助剂经搅拌捏合而成,它采用生物复配、聚糖交联、钙离子螯合等技术精制而成,有致密层、内防水层、胶网层和外防水层四部分构成。
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、纸浆模塑型木纸浆或芦苇、蔗渣、麦秸、稻草等一年生草本植物纤维纸浆经碎浆和净化,加入适量无毒化学助剂,成型、干燥、整型、定型、切边、消毒制成。产品的美观性并不高,同时也会增加废水的污染。
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、植物纤维型在环保优势上,植物纤维餐盒具有明显的优势,它是以稻草、稻谷壳、甘蔗渣等提取的植物纤维作为原料,加入成型剂、黏合剂、耐水剂等助剂搅拌通过成型机成型,加以干燥、整形、消毒等后期加工而成。这些农业的下脚料可成为工业原料,有助于农业资源的综合利用。
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.
在自然环境中,经过一段时间,一次性环保餐具是可以自己降解的,那么这也就解决的不可降解餐具对环境的危害问题。并且也节省了不可降解餐具的主要原料石油等不可再生资源。您有更多问题就来我们网站https://www.qiluxinke.com咨询了解吧。
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.
