Kev npaj ntawm graphene siv calcium carbide li cov khoom siv raw
Cov txheej txheem rau kev npaj graphene siv calcium carbide li cov khoom siv raw tshwj xeeb muaj cov kauj ruam hauv qab no:
(1) Ntxiv cov calcium carbide thiab surfactant nyob rau hauv ib tug sib npaug ntawm 50: (tswj qhov kub ntawm 50 ~ 12min, thiab tau txais cov pa roj carbon;
(2) Ntxuav tus rectorite nrog ethanol ua ntej, tom qab catalyst mus rau hauv lub microweave nrog lub rector-ntsaws rectorite rau catalyst yog rau catalyst yog 8: (0.1 ~ 0.3);
(3) Cov pa roj carbon rau cov kauj ruam (1) thiab cov tshuaj ntsuam uas tau muab tso rau hauv 10 ~ 80) yog qhov sib xyaw thiab sib xyaw ntawm lub nrawm ntawm 800 ~ 1000 teev. Nyob rau tib lub sijhawm, lub nqus hluav taws xob tsis zoo yog tig mus rau 5 ~ 10min, yog li ntawd tias cov pa hluav taws xob ua haujlwm tau thiab thaum kawg cov ntaub ntawv intoriteer nyob rau hauv lub rectorite interlayer cov pa roj carbon ntau yog tau txais;
(4) Tus kws kho mob rectLayer cov pa roj carbon rau hauv kauj ruam (3) ntxiv rau lub tshuab kaw qhuav, thiab tom qab ntawd cov kua qaub sib xyaw ntxiv. Nyob rau hauv kev tiv thaiv ntawm Argon roj ntawm 80 ~ 100mL \/ min, tus ntsuas kub, cov tshuaj tiv thaiv yog nqa tawm rau 3 ~ 8h, thiab cov sib tov yog ib txwm txias mus rau 20 degree. Tus rectorite raug tshem tawm nrog 30% ~ 50% nitric acid los ntawm huab hwm coj los muab cov khoom lag luam ua ntej;
(5) Cov khoom lag luam thawj cov khoom lag luam muaj nyob hauv kauj ruam (4) yog ziab nrog cov txheej me me uas muaj tsawg dua lossis muaj sib npaug rau 2nm.
Lub tshuab hluav taws xob hluav taws xob txo cov txheej txheem tam sim no tsuas yog cov qauv rau kev lag luam muaj calcium carbide.
Cov carbide nyob rau hauv molcide mlocide generated ntws tawm hauv qab ntawm cov tshuaj tiv thaiv rauv rau hauv lub tank, thiab cov khoom yog tau tom qab txias. Kev tsim cov calcium carbide yog qhov kev ua haujlwm hnyav, nrog ntau plua plav thiab muaj zog ntau. Thaum xyoo 1980, lub zog siv rau kev ua ib qho tuj ntawm muaj calcium carbide yog 10 txog 11 gj. Txhawm rau kom txo lub zog siv hluav taws xob, kaw thiab loj-teev calcium carbide furnaces feem ntau yog siv los txo cov cua sov ploj thiab pab txhawb nqa cov pa roj carbon monoxide.
