volcanic rock
volcanic rock
Type: 1-400
type: ash
Specification: 20-400
material: crater
Size: 1-400 (mesh)
applicable scope: building materials, chemical industry,
Mineral name: pumice, ash
Pumice for volcanic eruption postmagmatic cooling of the formation of a mineral, main component is silica, texture soft, small specific gravity can float on the surface of water, therefore calls the pumice, also called JiangMoShi (for shape and name).
Mineral form: pumice (the daughter party ") for amorphous. General for white, light gray, occasionally the pale red. Have standards of porous structure, and the shape of effective decay, sometimes with a tube structure. Surface dim or a silk luster. Sexual brittle. Small specific gravity, in the water can float. For volcanic eruption postmagmatic cooling of the formation of a mineral, main ingredients by vitreous (silica) composition, accidentally contain a small amount of crystalline mineral, texture soft, small specific gravity can float on the surface of water, therefore calls the pumice, also called JiangMoShi (for shape and name).
Mineral properties: pumice also called light stone, it is a kind of light porous vitreous rocks. It is magmatic eruption, due to the sharp pressure decreases, and the internal gas rapid escape expansion and formation. Pumice is acidic volcanic rock. Hardness is 6, lg/cm3 density less than, can float on the surface of water; Pumice insulation thermal insulation good; Porous and partition sharp. High chemical activity, absorbing strong, in the hydraulicity excitation agent has obvious under the action of water hard gelling properties.
The chemical composition of pumice is not stable, largely SiO2 65% - 75%, Al2O3 9% - 12%, Cao, Mgo, the sum of Fe2O3 for 30%.
Pumice is a kind of cheap natural building materials, development and utilization degree by all countries in the world industrial development level and the rise and fall of the building industry and change.
In today's world leisure complex with different style, style diversity, to top type multi-level development. For modern architecture group has the advantages of light weight, high strength, energy saving, shock, resistance to weathering, moisturizing, thermal insulation, sound-absorbing, non-toxic and cheap characteristics. Pumice products can fully satisfy the above technical requirements, is a kind of new building materials. Some countries for the development and utilization of day heat building sand material facing exhaustion, and pumice, ash, such as resource and poor, forcing its acceleration in domestic inside looking for substitute, add diatomite, expanded perlite, clay, shale, coal slag and fly ash, plastic powder, etc. The above materials comprehensive performance than pumice, ash and cinder is good, and the processing costs are more expensive and in building application subject to certain restrictions. And pumice, ash mining is simple, low cost health, and building industry in the countries all over the world get ordinary application. North America, Western Europe countries to import a lot of the foot domestic building industry needs.
Pumice, ash new USES for being found, range of application widen continuously, such as polishing, beauty, washing, fill section (fancy goods, decorating plate, sound insulation paint, textured paint) as special purpose products in the industry growing demand.
In quantity in the construction of industrial pumice dominated. But in value industrial pumice, ash predominate. Such as washing pumice in Britain price per ton 400 pounds, beauty with pumice per ton 5000 pounds, its profit amplitude is higher. Many manufacturers have turned to produce this kind of high value product. Such as parts of the eastern us from Italy imports - 6.4 mm pumice, make a second processing sale, $220 per ton.
Our country pumice resource is rich, in addition to production and building materials with pumice outside, should be the research and development of industrial grade pumice, depth processing, a large number of exports, occupy the international market.
Pumice comprehensive use
Pumice USES a lot of, the first used in building materials, with its as raw material processing of hollow pumice block is ideal red brick alternative products.
Pumice is still widely used in clothing processing, the finished garments with the "water" more soft, light, consumer is very satisfied. Now "washed clothing" has through the streets.
After processing by the pumice formation of pumice, is good "grinding polishing powder", can be used for the TV color picture tube surface polishing, all kinds of optical instrument lens polishing, various metal deoxidation polishing.
Pumice series products - "insulation poly slag agent" is widely used in casting metallurgy industry.
Use pumice scattered material to finish "wash feet stone" have promote foot blood circulation, healthy body, such as the second heart function.
In addition, pumice and develop new purpose - mainly used for natural light aggregate, thermal insulation materials, packing, etc.
Our country pumice, ash main purpose is as follows:
Building material: with natural light aggregate concrete. Such as external wall, floor, roof plate; Roof insulation, heat insulation layer; Small hollow block; Heat resistant concrete; Activity of cement mixed materials; Preparation without clinker cement; Building facing material department; Sound insulation heat preservation material.
Chemical industry: flour make filtering agent, drying agent and catalyst, oil chemical industry of the molecular sieve store enzyme carrier.
Plastics, packing industry: optical glass senior abrasive, plastic brightener, rubber packing, hard plastic packing, toothpaste, soap and daily chemical packing.
Other: pesticide carrier, fertilizer control agent.
Foreign pumice, volcanic main purpose is as follows:
Building materials: lightweight concrete such as plaster, decorating plate packing than ordinary mixing newspaper soil light 2%, high refractoriness 2%; Block brick, building the big board, bearing component, hydraulic and thermal, bridge engineering construction member; Railway ballast; Cement (with pumice as raw materials).
Abrasive industry: glass and glasses abrasive, soft metal and plastic brightener, tube and screen brightener, electroplating before polishing metal (silver, copper, furniture, Musical Instruments). Cleaning and friction wood, metal surface, stone.
Packing: metal cutlery abrasive cleaner. Circuit board cleaning abrasive. Soap, clothing washing to go up with household cleanser.
Daily chemical: beauty materials, toothpaste, machine using soap and cosmetics packing.
Petroleum chemical industry: molecular sieves. Like glue, asphalt, paper, paint, packing, filtering agent, pesticide carrier, ceramic, enamel glaze ingredients. Instead of light calcium carbonate for plastic filling.
Thermal insulation material: with pumice as the main raw material, after the high temperature melting into mineral wool and its products, used in the ceiling sound insulation.
Water meadows: with large pumice run of mine ore as raw material, reoccupy industrial colloid bonding together, can form a large-scale "water land", can make water pasture.
Industrial requirements
Ore quality usually require: loose density less than 1 g/cm3; Chemical composition, compressive strength, particle size distribution, water absorption rate, silt content for general index.
My company deposit mining technical conditions: minimum workable thickness of 0.5 m, clamp stone eliminate thickness more than 0.2 m,
