  一次性餐具按原材料来源、生产工艺、降解方式、回收水平分为以下三大类

  Disposable tableware can be divided into three categories according to the source of raw materials, production process, degradation mode and recovery level.
  一、生物降解类:如纸制品(含纸浆模塑型、纸板涂膜型)、食用粉模塑型、植物纤维模塑型等;
  Biodegradable products: paper products (including pulp moulding, paperboard coating), edible powder moulding, plant fiber moulding, etc.
  二、光/生物降解性材料类:光/生物降解塑料(非发泡)型,如光生物降解PP类;
  2. Photo/biodegradable materials: Photo/biodegradable plastics (non-foaming), such as photobiodegradable PP;
  三、易于回收利用材料类:如聚丙烯类(PP)、高抗冲聚苯乙烯类(HIPS)、双向拉伸聚苯乙烯(BOPS)、天然无机矿物填充聚丙烯复合材料制品等.巧妙鉴别:一次性餐具的优劣,可以通过“一看二闻三摸”的方式加以鉴别。
  3. Easy to recycle materials, such as polypropylene (PP), high impact polystyrene (HIPS), biaxially stretched polystyrene (BOPS), polypropylene composite products filled with natural inorganic minerals, etc.
  看:除了看包装上的生产企业名称、地址、生产日期等,还要对着光看,如果有蓝光或杂质很好不买。闻:有无刺鼻气味。方便筷子太白需要警惕:很多人在外就餐时认为一次性筷子比较卫生、安全,但一些小作坊为了降低成本,使用的都是劣质木材,为给筷子“美”,一些法分子会用硫磺熏蒸漂白,用这种筷子进餐时,残留的二氧化硫就随之进入体内。二是部分餐具密封性差,杯底容易渗水;三是少数餐具生产企业为了让杯子变得更白,就加入大量的荧光增白剂。
  Look: In addition to looking at the name, address and date of production of the manufacturer on the packaging, we should also look at the light, if there is blue light or impurities, it is very good to buy. Smell: Do you have a pungent smell? Convenient chopsticks are too white. Many people think disposable chopsticks are hygienic and safe when eating out. But in order to reduce costs, some small workshops use inferior wood. In order to give chopsticks "beauty", some methodologies will use sulfur to fumigate and bleach. When eating with these chopsticks, the residual sulfur dioxide will enter the body. Secondly, some tableware is poor in sealing, and the bottom of the cup is easy to seep; thirdly, a few tableware manufacturers add a large number of fluorescent whitening agents in order to make the cup whiter.
  根据学临床实验,荧光物质可以使细胞产生变异,荧光剂一旦进入体,就会成为潜在的致物质。餐具是我们用来接待客人不可缺少的一个物品,市场上不少商家利用人们不知如何挑选餐具,从而以次充好,那些不好的餐具很有可能会给我们身体带来伤害,所以我们一定要学会如何挑选餐具。本文将告诉大家如何挑选餐具。一次性餐具数字“3”代表该塑料的材质为PVC。这种材质高温时容易有有害物质产生,甚至连制造的过程中它都会释放,毒物随食物进入人后,可能引起新生儿先天缺陷等。目前,这种材料的容器已经很少用于包装食品。如果在使用,千万不要让它受热。一次性塑料餐盒餐具数字“4”代表该塑料的材质为LDPE。一般制品为保鲜膜、塑料膜等。耐热性不强,通常,合格的PE保鲜膜在遇温度超过111℃时会出现热熔现象,会留下一些体无法分解的塑料制剂。并且,用保鲜膜包裹食物加热,食物中的油脂很容易将保鲜膜中的有害物质溶解出来。因此,食物入微波炉,先要取下包裹着的保鲜膜.一次性餐具难以降解,全面回收处理尚有一定的难度。
  According to clinical experiments, fluorescent substances can mutate cells, and once fluorescent agents enter the body, they will become potential carcinogens. Tableware is an indispensable item for us to receive guests. Many businessmen in the market make use of people's ignorance of how to choose tableware to make it better. Those bad tableware are likely to cause harm to our health, so we must learn how to choose tableware. This article will tell you how to choose cutlery. The disposable tableware number "3" represents that the material of the plastic is PVC. This material is easy to produce harmful substances at high temperature, even in the manufacturing process, it will release, poisons with food into people, may cause congenital defects of newborns and so on. At present, the container of this material is seldom used to pack food. If used, do not let it be heated. The disposable plastic lunch box tableware number "4" represents that the material of the plastic is LDPE. Common products are fresh-keeping film, plastic film, etc. Thermal resistance is not strong. Usually, qualified PE fresh-keeping film will melt when the temperature exceeds 111 C, leaving some plastic preparations that can not be decomposed. Moreover, when food is heated by wrapping it with a fresh-keeping film, the oil in the food can easily dissolve the harmful substances in the fresh-keeping film. Therefore, when food is put into the microwave oven, the wrapped fresh-keeping film must be removed first. Disposable tableware is difficult to degrade, and it is still difficult to recycle.
  那么替代产品选什么合适呢?为了回答这个问题,必须对以下问题有充分的了解后方能得出科学的结论。在我国个城市的大街小巷,旅游景点、铁路沿线及江河湖泊。这种被废弃的一次性餐具随处可见,可谓触目惊心,给环境造成了严重的污染。这种“白色污染”不仅增加了环卫工人的劳动强度,给人们带来视觉上的污染,而且正日益严重的污染着我们赖以生存的土地资源和水资源,同样给人们带来了诸多的不便和危害。令人欣慰的是我国在这方面的研究已经做了大量的工作,并且取得了很大的成绩,加上在府的科学指导和强有力的支持下,各种环境餐具便应运而生,收到良好的社会效果.
  So what is the right alternative? In order to answer this question, we must have a full understanding of the following questions before we can reach a scientific conclusion. In the streets and lanes of cities in our country, tourist attractions, along railway lines and rivers and lakes. This kind of abandoned disposable tableware can be seen everywhere, which is shocking and has caused serious pollution to the environment. This kind of "white pollution" not only increases the labor intensity of sanitation workers and brings visual pollution to people, but also increasingly pollutes the land resources and water resources on which we live, and also brings many inconveniences and hazards to people. It is gratifying that our country has done a lot of work in this area, and has made great achievements. With the scientific guidance and strong support of the government, various environmental tableware emerged at the historic moment and achieved good social results.
                         生物降解颗粒
  可降解颗粒生产厂家首先将黄竹纤维和稻草纤维制浆,并参加糊精停止搅拌。待搅拌平均后,可降入单甘脂和柠檬酸,柠檬酸的作用就是调理pH值。之后参加填充料碳酸钙、加强剂、防油剂和防水剂平均混合。比较初的步骤徽鑫科一次性环保餐具厂家是将这些混合物倒入餐盒模具中停止压制成型,制成坚固、耐热、耐冷、耐酸碱、韧性好的可降解餐盒。将可降解餐盒埋入土壤中2周后开端降解,8周可完全降解,平安环保无净化。
  The degradable granule manufacturer first pulps the yellow bamboo and straw fibers and stops mixing with dextrin. After stirring, monoglyceride and citric acid can be reduced. The function of citric acid is to adjust the pH value.  After that, the filler calcium carbonate, reinforcing agent, oil-proof agent and waterproof agent were mixed equally. The first step Huixinke disposable environmental protection tableware manufacturer is to pour these mixtures into the box mould to stop pressing and forming, to make a solid, heat-resistant, cold-resistant, acid-alkali-resistant, tough degradable lunch box.  After burying the degradable lunch box in the soil for 2 weeks, it began to degrade. After 8 weeks, it could be completely degraded, safe and environmentally friendly without purification.
