The first layer and third layer to prepare raw material identical, be II type polyethylene of PERT, the II type polyethylene of PERT It buys from Tao Shi.
The II type polyethylene of PERT refers to the copolymer of ethylene and hexene, the preferably copolymerization of high density ethylene and hexene Object, the parts by weight of the high density polyethylene (HDPE) are greater than the parts by weight of hexene, and the weight ratio of the two is 95:(1-5).
The raw material for preparing of the second layer includes modified low-density polyethylene and PERT I.
In the present invention, the modified low-density polyethylene the preparation method is as follows:
1, low density polyethylene (LDPE) is prepared again: low density polyethylene (LDPE) and toluene being added in flask, under stiring heated Solution is prepared in dissolution, and the concentration of low density polyethylene (LDPE) is 3wt%-10wt%, is cooled to room temperature to it, is then used from preparation solution Syringe extracts solution, and the syringe equipped with low density polyethylene (LDPE) solution is fixed on the specimen holder of electrospinning device, Positive pole is connected with syringe needle, power cathode is connected with collector, starts sampling pump and opens high voltage power supply progress Electrostatic spinning closes high voltage power supply, sampling pump and collector after electrostatic spinning, stops spinneret, collects low density polyethylene (LDPE) Crude product；
2, by low density polyethylene (LDPE) crude product and the 2,2- dimethyl -3-butenoic acid being prepared in step 1, two isobutyl of azo Nitrile stirs evenly, and heating is reacted, and obtains modified low density polyethylene (LDPE)；
3, by the modified low density polyethylene (LDPE) of step 2 and reacting ethylenediamine, modified low-density polyethylene is prepared.
Wherein, in step 1,
The low density polyethylene (LDPE) is bought from Shanghai Su meter Information technology Co., Ltd, trade mark 2102TX00.
The spinning of the electrostatic spinning is 1 day a length of when carrying out.
The operating voltage of the electrostatic spinning is 26KV.
The distance of the spinning head of the electrostatic spinning to collector is 25cm.
The speed that pushes away of the sampling pump makes charging rate be 0.8ml/h.
The spinning head of the electrostatic spinning is the double spray heads of circle of concentric, therefore is prepared by electrostatic spinning low The pattern of density polyethylene is tubular structure.
In step 2,
The additional amount of the 2,2- dimethyl -3-butenoic acid is 5~20wt% of low density polyethylene (LDPE) quality.
The additional amount of the azodiisobutyronitrile is 2~5wt% of low density polyethylene (LDPE) quality.
The time being stirred to react is 6 hours, and the temperature of the reaction is 100 DEG C, and the reaction time is 2~3 hours.
In step 3,
The time of reaction is 8 hours, and the temperature of dewatering period is 140-160 DEG C, and the temperature of cyclodehydration section is 180-210 DEG C, the reaction weight ratio of the modified low density polyethylene (LDPE) and ethylenediamine is 0.3:1.
PERT I: the trade mark of heretofore described PERT I is PERT DX800, and business men is South Korea SK.
In the present invention, the weight ratio of the modified low-density polyethylene and PERT I are (0.1-1.8): 5, more preferably 1.2:5.
Another aspect of the present invention provides the process flow that the fuel supply process system generates gas: the liquefaction Fuel is branched into through the charge pipe on feeding tube first into the first head tank by charge pump, through the second branch of charge pipe Enter in the second head tank, first blower and the second blower by the first branch of air inlet pipe on the first admission line and Gas is driven into the first head tank and the second head tank by the second branch of air inlet pipe respectively, and the gas squeezed into generates pressure for the Liquefied fuel in one head tank and the second head tank branches into gas through the first branch of feed pipe and feed pipe second respectively In body generator.Superconducting fluid in heating device through inlet tube enter in heating mantle to the liquefied fuel in gas generator into Row heating, then flowed back into heating device through outlet tube.First blower and the second blower pass through the second air inlet pipe for gas It is driven into the inside of gas generator, is deep into the bottom of generator, promotes the gasification of liquid fuel；Liquid fuel after gasification It is transferred out through outlet pipe, it is to be used.
The gas generator outer wall is provided with side-mounted magnetic double level gauge, for monitoring the liquid in gas generator The liquid level of fuel, liquidometer can feed back the electric current of 4~20mA in different liquid levels, according to current values liquid level position.Institute The above liquid level and lower liquid level are the liquid level upper limit and liquid level lower limit set by us.When liquid level is lower than liquid level lower limit, the control Cabinet processed can control the amount of fan delivery gas, and open the solenoid valve on feed pipe, increase liquid fuel and enter gas Content in device；When liquid level is higher than the liquid level upper limit, control cabinet can close the solenoid valve on feed pipe, stop liquid fuel Addition.
It is provided with calorific value meter on the outlet pipe, for monitoring the calorific value of gas to be output, guarantees that the calorific value of gas is steady It is fixed.The output gas is the mixture of gas that gas after liquefied fuel gasification and the first blower/second blower provide.
When calorific value is lower than setting value lower limit, increase the gas content that the first blower/second blower provides, increases liquefaction combustion Expect the speed of gasification；When calorific value is higher than the setting value upper limit, the first blower/second blower stops working, and slows down liquefied fuel gas The speed of change.
The bottom of the gas generator is provided with liquid outlet, and the liquid outlet is recycled by raffinate recovery channel and raffinate Tank connection is opened the solenoid valve on raffinate recovery channel, raffinate is recovered to residual when the calorific value of gas to be output is very low always In liquid recycling can.
It is provided with blow valve and pressure gauge on first head tank, the second head tank and raffinate recycling can, works as input To the first head tank, the second head tank and raffinate recycling can gas it is excessive when, some pressure can be discharged from blow valve, prevented quick-fried It splits.
