Description
Technical field
The present invention relates to environment protecting tableware, more particularly to a kind of stone paper dishware and preparation method thereof.
Background technology
Ecological environment is the primary condition of human survival and development, is the basis of socio-economic development.The guarantor of ecological environment
Shield and improvement, are not only the significant problem paid close attention in the world, and are related to 21st century China's economy and social and hold
Supervention exhibition.Forest be the skylight of ecological environment, the mankind Green Ark, civilization cradle, research and practice have shown that, forest maintains
The future and destiny of the mankind, as the theme of land ecology, forest is the key for solving global ecological environment crisis, and it can
Air quality is improved, diversity of organism is effectively protected, prevents erosion, check desertification, prevent Soil degradation, be slow
The crisis of water resource is solved, eliminates or mitigates noise pollution.Forest is relationship environment and the tie of sustainable economic development, and it is can
Sustainable development provides physical environment basis, is the main body of bioenergy.
United nations environment form claims:The ecosystem of the forest as maximum most original on the earth, its area is past 30
The urgency in year only just reduces 94,000,000 hectares in the nineties in last century, Global Forests area, accounts for the forest gross area according to reduction
2.4%, indiscriminate felling of trees, overfarming makes the arable land in the world 23% seriously degenerate, and the land area in the whole world more than 1/3 faces desert
The prestige association of change, global water supply have also lighted red light.
Data shows, wooden ability total amount consumed is up to 1.7 billion cubic meters every year in China, and the country is only capable of providing 1.2 billion cubic meters,
Imbalance between supply and demand is very prominent, it is predicted that after 3 years, China's timber supply and demand breach will reach 6000-7000 ten thousand steres, by 2015
This numeral will reach 1.4-1.5 billion cubic meters.
Statistics shows:The annual production and application in China in catering trade disposable wood sanitary chopsticks up to 60,000,000,000 pairs, it is necessary to blow
The big tree of 25,000,000 growth 15 years is cut down, reduces the ten thousand stere of area of woods 200.The disposable lunch-box that China uses every year exceedes
12000000000, the disposal plastic cup and dixie cup of consumption up to more than 50,000,000,000, these Dining tool products for people provider just
While quick, many potential risks are also brought, a large amount of consumption and waste forest reserves, heavy damage people depend on for existence
Green ecological environment.They are not easily recycled, and the degradation cycle in nature is 200-400, will if being buried in soil
The saturating acid obstruction crop growth in soil is largely effected on, the lighter's digestive system is eaten by mistake by livestock and obtains seriously ill then death, if burning
Then discharge a large amount of harmful poisonous gases.Due to a large amount of the ecological ring being on the rise is caused using these discarded objects that accumulate over a long period
Border is polluted, and it is most to be invented by cake to have become global public hazards to be named as white pollution, annoyings China and generation
Boundary.
How to control and eliminate the sprawling development of this white pollution has turned into the Social Events of the world today.For this
Many countries and regions early begun to it is nontoxic can degradable or regenerated resources tableware material development, successively develop
Can the degradable disposable dinner ware made by the vegetable material such as starch and grain shell, straw, bagasse or to form sediment
Powder is the polypropylene biological degradable tableware of main component, and light, bio-degradable tableware and paper table ware are a variety of, wherein GPPS
Double down degrading dishware indices good process is simple, yield is cheap greatly, but it is undesirable to be a lack of recovery value degradation effect.
Light, bio-degradable tableware are that the starch of addition more than 50% and 10% photo-thermal electricity urge drop in acrylic material
Agent, it is this that chemistry does not occur instead with poly- hydrocarbons by the starch in the degradable dinner set of Main Ingredients and Appearance and auxiliary agent of starch
It should change, therefore, the property of its plastics do not change.With differing only in by shallow lake for common foamed plastics mess-tin
The effect of powder makes its fragmentation, does not solve the property of plastic foam fundamentally.Paper table ware has recovery due to itself
The value of recycling can carry out renewable resources, degradable back to nature, and not have any poisonous and harmful substance in degradation process
It is to generally acknowledge " green package " on our times to remain in big spontaneous combustion, but its raw material is wood pulp and straw pulp, and straw pulp production causes
Problem of environmental pollution compatriots all know that wood pulp largely consumes above-mentioned forest resourceies and destroys the ecological environment that people Men Lai has survived,
In addition the scarcity of resource be its can not sustainable development, be faced with ecology and the double contradition of environment.
