Abstract
The invention provides a foam ceramic used for the automotive exhaust treatment, a preparation method and a special die. The foam ceramic is made from burned organic silicone or organic metallic salts, tourmaline, clay and foam stabilizer. The technological process is: evenly mixing the tourmaline, the clay and the foam stabilizer of 300-2000 order, adding the organic silicone or the organic metallic salts to prepare uniform tourmaline slurry; adding the uniformly prepared tourmaline slurry in a die, which is put in a kiln and burned at 300-750 DEG C. The special die is conical structured, and a lifting rod is arranged in the die. Under the low temperature without destroying the structure of the tourmaline, the invention makes use of the organic silicone (or the organic metallic salts) to solidify and sinter the powder body of the tourmaline. Blistered foam ceramics are formed, which increase the contact surface with exhaust. And the tourmaline generates negative oxygen ions with higher activity to purify harmful substrates in the automotive exhaust.
Description
Affiliated technical field
The present invention relates to a kind of foamed ceramics and making method and particular manufacturing craft that vehicle exhaust is handled that be used for.
Background technology
Along with improving constantly of living standards of the people, motor vehicle quantity also sharply increases, and has also brought the serious environmental pollution when bringing convenience to people's life, and human beings'health has been caused huge threat.The atmospheric pollution of the U.S. has 60% approximately for transport facility causes according to statistics, causes that by automobile the situation of China also allows of no optimist in Japan about 85%.Current automobile exhaust gas has become city primary pollution source.Automobile start with driving process in the pollutent of discharging mainly contain carbon monoxide (CO), oxynitride (NOX), hydrocarbon polymer (HC), aldehyde (RHCO), plumbous particulate matter etc.At present, handling vehicle exhaust has numerous methods, still is blank but utilize tourmalinite to carry out the vehicle exhaust processing.
Summary of the invention
The object of the present invention is to provide a kind of foamed ceramics and making method and particular manufacturing craft that vehicle exhaust is handled that be used for, this mode utilizes the fluctuation of heat of vehicle exhaust bigger, and the characteristic that contains a large amount of water vapors in the tail gas, make tourmalinite produce negative oxygen ion, with objectionable impurities (CO, the NO in the tail gas with greater activity
X, HC, RHCO etc.) be oxidized to the little or avirulent material of toxicity, thereby reach the effect of purifying automobile tail gas.
The technical solution adopted for the present invention to solve the technical problems is:
Described foamed ceramics is fired by organosilicon, tourmalinite, clay and suds-stabilizing agent and is formed.
Described foamed ceramics is fired by organic metal salt, tourmalinite, clay and suds-stabilizing agent and is formed.
Described foamed ceramics manufacture craft flow process is: A, 300-2000 purpose tourmalinite, clay and suds-stabilizing agent are mixed, add organosilicon and be modulated to uniform tourmalinite slurry; To modulate uniform tourmalinite slurry and add in the mould, put into kiln, fire 3-5h at 300-750 ℃.
Described foamed ceramics manufacture craft flow process is: A, 300-2000 purpose tourmalinite, clay and suds-stabilizing agent are mixed, add organic metal salt and be modulated to uniform tourmalinite slurry; B, will modulate uniform tourmalinite slurry and add in the mould, put into kiln, fire 3-5h at 300-750 ℃.
Described particular manufacturing craft is a tapered structure, is provided with motion bar in the mould.
Described organosilicon, tourmalinite, clay and suds-stabilizing agent are followed successively by by weight percentage; 10-50%, 10-25%, 35-70%, surplus
Described organic metal salt, tourmalinite, clay and suds-stabilizing agent are followed successively by by weight percentage: 20-50%, 20-40%, 25-55%, surplus.
Described organic metal salt is be selected from organic zinc, organic-magnesium, organic iron, organoaluminum, organic titanium at least a.
Described tourmalinite is a 300-2000 purpose powder.
The invention has the beneficial effects as follows: characteristics of the present invention are not for destroying in lower temperature (300-750 ℃) with organosilicon (or organic metal salt) under the case conditions of structure of tourmalinite, realization is to the curing nodulizing of tourmaline powder, form the foamed ceramics of many pores, increase contact area with tail gas.Make tourmalinite produce the negative oxygen ion with greater activity, the objectionable impurities in the purifying automobile tail gas rapidly.
The present invention is further described below in conjunction with embodiment.
Embodiment 1: by wt%, get 35% tourmalinite, 20% organosilicon, 40% clay respectively, surplus is a suds-stabilizing agent.
