Description
Technical field
The present invention relates to a kind of used in electronic industry clean-out system and preparation method thereof, particularly a kind of cleaning agent for waste teletron broken glass and preparation method thereof.
Background technology
At present, according to scholarly forecast, in five to 15 years of future, the CRT picture tube date of retirement that China produces, and advanced countries such as American-European and Japan just met with the peak that electron wastes (containing the CRT picture tube) is scrapped at hand.From the Communication Development statistical communiques in 2005 that the Ministry of Information industry announces, learn, China's number of netizens has reached 1.11 hundred million, conservative estimation, what have wherein that 60% people uses is (CDT glass bulb) typotron, this means in following 5-10, will have 0.666 hundred million useless (CDT) (being roughly equal to 1,000,000 tons of glass cullet) indicating meter scrapped successively.This number does not also comprise colour (CRT) televisor and the eliminating of individual (CDT) computer monitor of not networking.At first enjoy the western developed country of electronic product benefit, may not reckon with the environmental stress that electronic waste brings at first, the situation that they are present, the perhaps problem of the many environmentalists of China worry just.According to expert statistics, China obtains useless using glass bulb from telecomputer is scrapped will be increased to annual 600000 tons year by year from ten thousand tons of 15-20 every year, and this is unavoidable environmental pressure.And useless using glass bulb is different from common domestic glass, and composition is special, includes PbO, BaO, and SrO, ZrO and top coat fluorescent material contain graphite and halogen composition in the coating.Both at home and abroad the expert thinks, the coating that contains graphite is through glass-melting furnace high temperature, may form strong carcinogens such as dioxin and enter atmosphere by factory chimney.Contain the CRT glass of special composition, as be submerged, when condition was suitable, objectionable impurities can be dissolved in soil and the water source once more.Therefore, press for safe recovery and reuse CRT image tube broken glass, reduce its harm and pollute.At present, waste image tube recovery and reuse optimal path is to become the raw material of making CRT glass once more.Decoating is very necessary, except preventing generation of dioxin, also for the glass sophisticated categories, because the coating influence is classified and then influenced glass cullet reuse at high proportion.
The method of current decoating and cleaning glass has three kinds:
The manual cleaning: adopt simple basket, net, use the HF acid soak, remove coating, stay glass, discard raffinate; The objectionable impurities that operating process discharges will cause damage to workers ' health.The cleaning raffinate is dealt with improperly, and environmental pollution is very serious.
Cylinder dry method: adopt grinding plant,, glass coating is removed by a glass grinding mutually.But the processing noise is big, the difficult control of dust, and the glass yield is low, accounts for nearly 10% the difficult utilization of glass micro mist.
Cylinder wet method: utilize roller equipment that glass is immersed among the HF, remove coating by chemical action and certain mechanical effect.The loss of this kind method glass is little, but HF acid is bigger to operator's actual bodily harm, the wastewater treatment difficulty; And HF is the clean-out system that domestic and international general limitation is used.
Waste image tube broken glass coating clean-out system is also being set about developing by the country that also has, but must add the cerium oxide composition, and cost is higher.
