Abstract
A method for using waste plastics to produce light concrete building material included two steps, namely mfg. light particles and mfg. light concrete, at first the non-degradable foamed polystyrene, polyethylene, foamed polyethylene waste plastics are made into 1-8 mm sheets or irregular particles, and degreased, then the obtained light particles are mixed with cement uniformly instead of commonly-used light aggregate to produce concrete according to conventional method. Its advantages include simple technology, less energy consumption, low cost, save cement by 15-20%, good product quality, eliminate environmental pollution etc.
Description
In recent years, along with the development of catering trade, the consumption sharp increase of mess-tin.The disposable snack box overwhelming majority who widely uses at present makes as expanded plastic, because this material non-degradable under the Nature condition, the depleted cutlery box is seen everywhere at avenue, greenery patches, public place and railway, both sides of highway, is referred to as by people " white pollution ".It is buried in underground because plastics need could to degrade more than 200 years, thus can secluding air, the soil that hardens grows germ, the polluted underground water source; If with its burning, can produce obnoxious flavour again, atmosphere pollution, the health of harm humans.And in fact, " white pollution " never only refers to nondegradable disposable plastic cutlery box, the instant noodle bowl of selling on the market, various food-packaging bag, fruit net, portable shopping bag, refuse bag, the interior filling foamed plastics liner of household electrical appliances packing box etc., all be the generally source of causing environmental pollution, plastics pollution has arrived instant stage.Common treatment process is with its recovery, with plastics oil refining or reprocessed plastic(s) etc.Plastics extract polymerization from oil, consumed a large amount of energy therebetween, are plastic cracking tank oil and consume a large amount of energy now, and we think the waste on a kind of program.What is more important is built a factory to be needed more than several kilotons of plastic waste every year at least, and plastic waste is in light weight, and volume is big, dispersion range is wide, the end product value of plastics oil refining production is low in addition, causes purchasing price low, therefore far can not satisfy the demands by reclaiming plastic garbage.
The objective of the invention is to utilize some plastics itself to have premium propertiess such as good mechanical property (specific tenacity), lightweight, insulation, sound insulation, and other plastics also can reach these performances by processing, filling foamed plastics liner in depleted disposable plastic goods such as plastics cutlery box, instant noodle bowl, various food-packaging bag, fruit net, portable shopping bag, plastic cup, refuse bag, the household electrical appliances packing box is used for the Development and Production light concrete construction material, comprises lightweight body of wall, light-weight hollow-brick, light weight concrete aggregate.The exploitation of this new purposes on the one hand can thoroughly be eliminated the harm that " white pollution " causes environment, on the other hand, for construction industry provides building materials raw material new, with low cost, excellent property, construction industry is produced positive influence.
The method that plastic waste provided by the invention is used to produce light concrete construction material comprises to be made light granules and makes light weight concrete two portions.
One, utilize plastic waste to make light granules
The raw material of selecting for use is filling foamed plastics liner etc. in (1) polystyrene foamed, polyethylene kind waste plastic product such as disposable lunch-box, instant noodle bowl, fruit net, the household electrical appliances packing box; (2) common polythene waste plastic product such as various food-packaging bag, plastic cup, portable shopping bag, refuse bag etc.
To (1) class raw material, foamed polystyrene class, polyethylene foam class plastic waste are cut into sheet or the irregular particle of 1-20mm, water cleans a little, and the flush away greasy dirt gets final product;
To (2) class raw material, common polythene class plastic waste is cut into sheet, water cleans decontamination, dries, and with plastic working wire drawing tablets press granulation already commonly used, the polyethylene grain of making is made the bar that diameter is 1-20mm with plastic foamed forcing machine, is cut into granular.
Two, make light weight concrete
According to the method that routine is produced light weight concrete, the light granules that plastic waste is made substitutes mineral light-weight aggregates such as pearlstone commonly used, vermiculite, zeolite, haydite, and is reinforced, mixes to get final product.
The light concrete construction material that adopts method provided by the invention to make, its advantage is:
1, technology is simple, and it is few to consume the energy;
2, production cost is low, can save the cement of 15-20%, and its reason is that perlite can shrink refinement in stirring, and cement is absorbed its inside, makes mixed concrete material volumetric shrinkage, therefore will add into cement; And expanded plastic does not have this phenomenon substantially.
3, construction industry is produced positive influence, make the building structure lightweight, reduce building cost significantly, the good soundproof effect of light building material can reduce city noise pollution, good heat-insulating property can be saved the energy that the heating of air-conditioning consumes, and has reduced heating system fire coal etc. simultaneously to atmospheric pollution;
4, the demand of building materials is very big, utilize plastic waste to produce building materials and have higher input-output ratio, thereby can significantly improve the procurement price of plastic waste, according to preresearch estimates, procurement price can be brought up to 3 yuan/kilogram from present 0.4-0.8 unit/kilogram, so social unemployed understands conscious joining and picks up the ranks of collecting plastic waste, guarantees its raw material abundance.
5, can make full use of waste resource, turn waste into wealth, can eliminate the white pollution thing again, eliminate environmental pollution, have tangible economic results in society.
Several embodiments of the present invention are provided below.
Embodiment one:
Utilize plastic waste to make the roof heat insulation concrete.Earlier the foamed polystyrene disposable lunch-box that reclaims is cut into sheet and the irregular particle of 1-4mm and 4-20mm respectively, the light granules of two kinds of granularities is by the heap volumetric metering; Water cleans degreasing, preferably adopts the air-flow ultrasonic method to clean; By big pellet 50-70%, small pellets 30-50% mixes, and every square metre of light material adds 400-700 kilogram Portland cement, stirs with ordinary method, and thickness paves and gets final product on roofing on request.Its intensity can reach 1-4MPa, thermal conductivity 0.06-0.1W/M.K, unit weight 0.44-0.76M
3/ T, this concrete can be used for directly annotating refrigeration storehouse body of wall.
Embodiment two:
Plastic waste is used to make thermal insulation mortar.The polyethylene kind plastics bag that reclaims, plastic cup etc. are cut into sheet; Water cleans the decontamination stain, dries; With plastic working wire drawing tablets press granulation already commonly used; The polyethylene grain of making is made the bar of diameter 4-20mm with plastic foamed forcing machine, cuts into light aggregate again, by the heap volumetric metering; Every cubic metre of light material adds 300-500 kilogram (also can add the part lime), stirs with ordinary method; Smear on interior wall that to hang 3-5cm thick and flatten and get final product.The interior metope that this method is made can be nailed.
