Background technology

Diatomite is from the oceanogenic sedimentation before millions of year,, by ancient times the diatom remains form, its Chemical Composition is mainly SiO 2, contain a small amount of Al 2O 3, Fe 2O 3, CaO, MgO, K 2O, Na 2O, P 2O 5And organic matter.SiO 2Usually account for more than 80%, reach as high as 94%.The diatomaceous iron oxide content of high-quality is generally 1~1.5%, and alumina content is 3~6%.Diatomaceous mineral composition is mainly opal and mutation thereof, is secondly clay mineral-hydromica, kaolinite and mineral chip.Mineral chip has mica and organic matter.

Under electron microscope, diatom is vesicular structure, and countless small holes and material character have the chemical effect of unique physical adsorption function and removing formaldehyde.People for the building room that day by day enters relative closure, for the pathogenic people of pollution that bring because of indoor hardware fitting that are on the increase in society, look forward to having a kind of oligosaprobic ecological decoration material that falls, so the inner wall decoration material take diatomite as main component has come out, but because people's understanding deepens constantly, be the coming up of decorative material for internal wall of main component along with diatomite, some problems need to be resolved hurrily, all if any product strength poor, can not recycle; Some use resene binding agents have stopped up diatomaceous small pore, and the decomposing formaldehyde ability descends; Water-intake rate is low, function singleness; Some producers are used for the house decoration material with rare industrial raw material; The product self that also has does not have antibacterial, causes indoor secondary to pollute; The quality that also has is low etc., makes people pay expensive tuition fee.

At present, the products such as diatom great soil group material used of comprehensive inner wall decoration both at home and abroad probably have three classes:

Gelling material in the product: 1. adopt cement based; 2. adopt tackiness agent (resene) to cohere.3. adopt in a large number industrial gypsum and other inorganic mineral.

Character from the product matrix material: 1. single employing is diatomaceous; 2. the inert mineral fillers that add, use diatomaceous less; 3. follow the line of least resistance, add in a large number high molecular polymer.

From the functional effect of product: owing to too emphasizing and relying on the single performance of diatomite, though adopt in a large number diatomite essence soil, do not note and each function mineral organic composite adsorption-decomposition function formaldehyde, noxious odor DeGrain.The also mineral powder of a large amount of composite kaolin, mica group that has just contains a large amount of kaolinites and micaceous clay ore deposit in fact in diatomaceous associated minerals, highly beneficial to decorative material moulding and the functional stack of diatom great soil group.

1, diatomite itself does not possess into the gelling of mud, and in order to improve its bonding and intensity, some employing cement based are as gelling material, and diatomite not only can't recycle, and has limited diatomaceous adsorption function, and the most direct effect is exactly that water-intake rate descends.

2, the use resene binding agent that has has stopped up diatomaceous small pore, and the decomposing formaldehyde ability descends; A large amount of employing macromolecule adhesives brings into benzene, ammonia, formaldehyde etc. indoor unavoidably simultaneously.

3, the diatomite main component is opal, and is the same with other material of construction, and erosion and the pollution of various moulds are arranged, and do not take measures, and also can carry it in the room of finishing.

4, single utilization diatomite.Nature has many mineral additives that possess excellent function, can use with diatomite is collaborative, make the more perfect function of diatom decorations mud, but irrational interpolation inert mineral filler, not only strength at break, also may bring heavy metal in diatom great soil group decorative material.

5, adding of a large amount of organic high molecular polymers, be unfavorable for fire-retardant.

6, criticize scraping property bad.Because each component ratio is unreasonable, the rapid hardening of some diatom great soil group decorative materials, some shortage plasticity is difficult to machine-shaping.

7, cost is high, and unreasonable use causes waste of material.Diatomite belongs to Nonrenewable resources, and abuse will shorten diatomaceous Sustainable Development and Utilization.

Although China's diatomite resource reserves are abundant, widely distributed, high-quality soil is less, the diatomite that can directly be used in industrial goods only has the minority mining area, quite a few needs import, but much higher-grade diatomite is used on material of construction in the past, is the broaden application field, improve product specification, the change resources advantage is economic advantages, with low-grade diatomite rational gradation composition, to the application of being purified of diatom clay and mine tailing, can take full advantage of local resources, make the increment of diatom mineral products.
