Description
Technical field
The present invention is applied in architectural decoration, is related to a kind of preparation method of Light Wall.
Background technology
Material mine exploitation brings more than 70% barren rock material, handles these barren rock material or land occupation is stacked or filled out
Bury, damaged substantial amounts of valuable soil, rock material resource is become environmentally hazardous one big public hazards.Barren rock material is selected removes for these
A part of handicraft, colored stone sand grains are produced, the marble wastes of high whiteness are produced beyond some light powdered whitings, other equal nothings
Effectively there is the method for economic value to utilize it.It is unbroken it is tens of in each mining area be seen everywhere colors stone riprap clinker Cheng Shan
Cheng Ling, fills up gully, and ruinate environment also easily forms mud-rock flow.
With the development of modern industry and the surge of world population, energy crisis, crisis in food, environmental crisis day are increasingly
It is acute.World economy is too dependent on the fossil resources such as oil, coal, and its is non-renewable just to cause such resource gradually withered
Exhaust, and price is climbing up and up, and such resource of burning produces gas and the suspended particulates such as substantial amounts of carbon dioxide, sulfur dioxide
Thing has resulted in the worsening of climatic environment.Find reproducible clean energy resource and substitute them as the concern of scientific research department of various countries
Focus.Wherein biomass energy is because excellent with wide material sources, cheap, strong, the carbon dioxide reusable edible of recyclability etc.
Point, turn into most potential energy substance.Ethanol has been attached great importance as regenerative resource, at present, the life of alcohol fuel
Production is mainly using grains such as sugarcane, cereal as raw material, but population expansion, food shortage determine this raw material production alcohol fuel
Limitation.Cellulosic ethanol is derived from the important energy source of renewable biomass.Lignocellulosic be it is most abundant on the earth can be again
Production-goods source, every year by about 1,000,000,000,000 tons of plant cellulose caused by photosynthesis, to avoid striving grain with people, ground, wood being striven with grain
Matter cellulose is as the most potential raw material of the production of cellulosic ethanol.From the point of view of at this stage, most area is made by stalk
For fuel, or directly burned in field, not only pollute environment, and because the utilization rate of straw burning energy is low,
Cause the serious waste of resource.Making raw material cellulose ethanol using agricultural wastes has without soda acid steam explosion, enzyme hydrolysis work
Skill mild condition, equipment are simple, energy consumption is low, it is environment-friendly the features such as.Not only can the substantial amounts of conversion of biomass energy, alleviate energy
Source crisis, but also atmosphere pollution can be alleviated, improve the ecological environment, promote agricultural sustainable development, drive agriculture industrialization
And benign ecological cycles.Last remaining slag charge is lignin, can be in many because lignin is natural high molecular substance
Field replaces petroleum chemicals productive target organic products.
Artificial stone typically refers to artificial solid material, artificial stone quartz, artificial stone hilllock stone etc..Artificial stone type is not
Together, its composition is also not quite similar.Composition is mainly resin, aluminium powder, pigment and curing agent.Artificial stone is that " high polymer material polymerize
Body ", typically using unsaturated-resin and aluminium hydroxide inserts as main material, the technological forming such as agitated, cast, heating, polymerization
" macromolecule solid slab ", commonly referred to as:" resin plate artificial stone ".
Resin type artificial stone be using unsaturated polyester resin as cementing agent, with aluminium hydrate powder, natural marble rubble,
Quartz sand, calcite, stone flour or other inorganic fillers coordinate according to a certain percentage, and it is outer to add catalyst, curing agent, pigment etc.
The process such as agent, blended stirring, curing molding, demoulding drying, surface polishing is added to be process.
Shortcoming one:Resin type artificial stone is using unsaturated polyester resin as cementing agent, because unsaturated polyester resin is
Liquid, other inorganic fillers are solid powder, are not easy to be well mixed during mixing, during mixing easy heat production cause resin solid in advance
Change, cause finished product sheet material material uneven, easily cracking, buckling deformation.
Shortcoming two:Resin type artificial stone is that resin demand is too big using unsaturated polyester resin as cementing agent, causes finished product
Board cost is higher, non-refractory and belongs to combustible material.
