Introduction to the new craft of recycled glue of Ding Ji
2007/10/5
Man base rubber ( IIR) It is a kind of artificial synthetic rubber made in different butene and rare copolymerization of different fifth two. Because man base rubber have airtight nature fine, ventilative rate low, heat resistance, ageing-resistant performance, acidproof able to bear soda and able to bear polarity solvent advantaging, make tire inner tube of a tyre, capsule, medicine and use such irreplaceable high-quality elastomer materials as the bottle plug,etc..
2005, the volume of consumption of Chinese cube base rubber is nearly 150,000 tons, base rubber of domestic man is fewer than 30,000 tons, 80% depended on import, from 1999 to 2004, the average annual rate of increase of the import volume was up to 26.9%. Because, international petroleum market price rise constantly, man base rubber price is soar constantly too. It is in recent years it rise not appearing from 15000 yuans / about T price, man of base rubber in 32000 yuans /above T. And though man base price, rubber of products rise to some extent, charge price ascensional range to exceed 30% wholly, can't far catch up with the rising at double of rubber price of man's base. So do a lot of enterprises which use the man base rubber turn sight to the best substitution of the man base rubber? Taste - -Ding Ji reclaimed rubber.
Ji Ding reclaimed rubber have some special cooperation advantages even except performance of the similar original polymer, such as improving size stability, it is relatively low to rise hotly, reduce and burn burntly. The airtight is the same as the base rubber of original man, keep various kinds of performance of growing the glue originally better than other synthetic rubber, so the management of the recycled glue of man's base makes tire inner tube of a tyre best choice material well. Man base rubber contain a small amount of different fifth two alkene, so its the degree of saturation is lower, its ageing-resistant performance of vulcanization glue is very fine, this proves it is very able to bear oxidizing, through is it prove, is it sulphurate man base rubber when the regeneration, the function that oxygen plays is very little to abolish too to test, so difficulty than the natural rubber of recycled desulphurization.
The growing of recycled glue of Ding Ji in China at present? The craft has the amount of kind six seven, mainly steams cooking methods, fries and makes the law, pushes out of the law, microwave law, radiates the law, high temperature continuous catalysis law, mechanical law of chemistry etc., but no matter which kind of method is adopted, the purpose is to adopt the most economic, most scientific method to turn abolishing the cube base rubber from netted structure into the line type structure.
As Chinese tire industry develops fast, the volume of consumption of cube base rubber rises fast, especially fast development, meridian of tire, in addition, country " man of medical use bottle plug base" standard issue, the country proposes man's base of inner tube of a tyre of the tire, the powerful demand for the cube base rubber of domestic and international markets, have promoted the development of recycled glue of man's base. But because is the recycled glue of Ding Ji in China one grown? Being in short supply, raw materials abolish man base inner tube of a tyre by 2000 of the year before last / T large, go up to present 6100 yuan / about T, abolish the capsule and rise by 3800 yuan / about T up till now from side to side from 800 yuan / T, the medical bottle plug rises by 2000 yuan / about T at present from side to side from 1000 yuan / T. Ji Ding recycled although glue price is it rise to have, is it abolish man base glue rise the range in price to happen. So cause a lot of cube base recycled glue producers to turn from usury into the meagre profit or profitless. Analyse its reason is mainly raw? The craft method lags behind, grow? Man recycled in base for glue thing have the getting lower too indicator, can only sell at a low price, but grow? The producer is profitless, and has wasted a large number of valuable resources.
I have improved the traditional desulphurization craft through the trying to find out of more than two years, is it is it smelt law craft carry on man base recycled glue desulphurization, craft this is it invest in province, craft simplify, born to have to pinch to adopt? With high efficiency? Is it of high quality and growing to taste? Such advantages as economy is profitable with low costs, and there are no waste liquid, secondary pollution of abolishing the vapour. The whole desulphurization course does not exceed 13 minutes, and the desulphurization is even, the ones that have overcome the coking, carbonization phenomenon? Grow, make Ding Ji's recycled glue finished product keep the best thing indicator.
Traditional desulphurization method prevail relatively in China at present, whom most producer select for use to burn and fry the desulphurization of the pot, the shortcomings of above-mentioned two kinds of methods are: Dynamic desulphurization, has just offered the desulphurization condition of the high-temperature high pressure, desulphurization time is long, the ones that need to join and cost an arm and a leg soften the auxiliary, the more important thing is that can't rub and push to desulphurization raw materials. So will cause the surface coking of raw materials, carbonization, the inside of raw materials can't be taken off completely, cause? Have tasted the surface and solved the particle gathered and existed, have influenced? Taste quality. The baked wheat cake can't control temperature accurately while frying the pot, carbonization compare with coking phenomenon dynamic desulphurization the serious even,so? The thing indicator tasted is unsatisfactory too. Is the greatest problem of the above-mentioned two kinds of desulphurization methods? Grow abolishing the vapour secondary pollution of a large amount of. Pinch the advantage of smelting law desulphurization
First, do not use the auxiliary costing an arm and a leg, in case of necessity? Obtaining lower door Buddhist nun's viscidity only needs to join and soften the pharmaceutical partly ( Machinery oil) .
Second, the equipment is with little investment, a day? 7- 8 man base recycled desulphurization of glue special-purpose to pinch person who smelt, is it take 170,000 only to invest once only. Only need to mix an 1.63 air compressors.
Third, temperature control accurate? Obtain the best door Buddhist nun's viscidity, only need to adjust the temperature of pinching the smelting machine. Viscidity ML of Buddhist nun of door ( 1+ 4) 100 degrees Centigrade can be adjusted wantonly among 40-6.
Fourth, draw such thing indicators as the intensity,etc. to lose small. Abolishing the foetus and carrying on the random sampling to using, measure the average before processing. The recycled glue after processing draws intensity value, the average after processing has only dropped 0.3- 0.5MPa. This is that other desulphurization way is incomparable. Is it smelt base, man of temperature control, law of desulphurization recycled source of raw materials of glue extensive to pinch, uneven to differ, abolish inner tube of a tyre with man base but speech, supreme draw intensity can up to 10MPa to be the above-mentioned, it is the lowest there is only 6.3MPa, so proportion is different.
Test through the long-term observation, the critical temperature high in intensity, with light proportion is low. The critical temperature is high on the contrary, the level of the content of cube base glue determines the level of the critical temperature of desulphurization. Each raw materials it enters to be must to to is it give up intensity or proportion go on at random inspecting by random samples to tear raw materials after the factory, then calculate out desulphurization temperature according to the real data ( Namely critical temperature) . Man base capsule,etc. man base raw materials, sulphurate system sulphur, but resin sulphurate system or chlorine inferior tin sulphurates the system, desulphurization temperature should be relatively high. Quality quality of the recycled glue of Ding Ji of impact on Buddhist nun's viscidity of the door of temperature, its first thing indicator is Buddhist nun's viscidity of the door, then draw the intensity and break the extending rate.
The reason at present? Raw in China? Big man base recycled Buddhist nun of glue door viscidity that enterprise use, base of inner tube of a tyre, man of type, demand ML ( 1+ 4) 100 degrees Centigrade of 55¡À 5, and grow? The required door Buddhist nun's viscidity of enterprise of such small-scale inner tube of a tyres as the bicycle, motorcycle,etc. is ML ( 1+ 4) 100 degrees Centigrade of 45¡À 5, some special enterprises even require viscidity ML of Buddhist nun of door (1+ 4) Under 100 point 40 degrees Centigrade. Door Buddhist nun viscidity high to draw intensity to be too high, but craft good, door Buddhist nun viscidity low to draw intensity to be low even, but the craft is good.
So while pinching and smelting France's desulphurization? Guarantee intensity indicator, reduce Buddhist nun's viscidity of the door, can put into and soften the pharmaceutical (machinery oil) Adjust Buddhist nun's viscidity of the door. It belongs to the artificial synthesis glue that the critical temperature and heat oxidize and control the man base rubber, so it is very crucial to control the good critical temperature by pinching and smelting France's desulphurization, is rubed in raw materials are pinching the smelting machine, while pushing and intensifying to the critical temperature, have already finished dissolving bloated, activate, the course that machinery is solved and gathered,etc., then hot oxidizing process, can't lower the temperature in time, discontinue hot oxidizing process sizing material the coking and carbonization, it is essential to so control the critical temperature and discontinue the hot oxidizing process in time.
Must put into and open the smelting machine to cool in time. Does the method to control pollution pinch and smelt the growing of recycled glue of cube base of France's desulphurization? Course here just for hour such as critical temperature? Grow a small amount of atomized exhaust gas. Installation is collected and covered angrily above pinching the smelting machine, send the fan into water curtain condensation to get rid of the cigarette device, can discharge harmlessly. Condensation water can is it is it use to enclose to go back, water floating thing included can is it is it soften the pharmaceutical or make the fuel to manufacture to pull out.
