Intshayelelo kunye nokuhlelwa kwemveliso ye-coal tar pitch

I-Coal pitch, isifinyezo se-coal tar pitch, i-coal tar distillation processing emva kokususwa kwe-liquid distillate residue, yeyohlobo lwe-asphalt yokwenziwa, ngokubanzi yeyolwelo oluqinileyo, oluqinileyo okanye oluqinileyo, olumnyama nolukhazimlayo, ngokubanzi luqulathe i-carbon 92 ~ 94%, i-hydrogen malunga ne-4 ~ 5%. I-Coal tar pitch yimveliso ephambili kwinkqubo yokucubungula i-coal tar kwaye sisixhobo esingasetyenziswa endaweni yaso sokuvelisa i-carbon.

Injongo yokucocwa kwetha kukuqokelela izinto ezinamanqaku afanayo okubila kwitha zibe ziinxalenye ezifanelekileyo ukuze kuqhutyekwe phambili kwaye kwahlulwe iimveliso ze-monomer. Intsalela yokukhupha i-distillate yi-coal tar pitch, ebalelwa kwi-50% ukuya kwi-60% ye-coal tar.

Ngokweendawo ezahlukeneyo zokuthambisa, i-asphalt yamalahle yahlulwe yaba yi-asphalt yobushushu obuphantsi (i-asphalt ethambileyo), i-asphalt yobushushu obuphakathi (i-asphalt eqhelekileyo), i-asphalt yobushushu obuphezulu (i-asphalt enzima) iindidi ezintathu, udidi ngalunye luneNombolo 1 kunye neNombolo 2 iiklasi ezimbini.

I-bitumen yamalahle isetyenziswa kakhulu kwezi ndawo zilandelayo:

* Ipetroli: Izinto eziqinileyo zingaxutywa neoli enzima okanye zenziwe zibe ludaka olusetyenzisiweyo, zinokudlala indima yokutshintsha ioli enzima.

Ipeyinti: Ipeyinti eyongeza i-rosin okanye i-turpentine kunye nezizalisi xa kuphekwa ioyile kwizakhiwo okanye kwiipayipi ezingangeni manzi. Ifanelekile kwisakhiwo sentsimbi sangaphandle, kwikhonkrithi nakwimayini engangeni manzi kunye nomaleko okhuselayo, kwaye ingapeyintwa kwaye ipeyintwe kubushushu begumbi.

* Ukwakhiwa kwendlela, izixhobo zokwakha: xa kuthelekiswa ne-petroleum asphalt, i-coal asphalt kunye ne-petroleum asphalt, kukho umsantsa womgangatho ocacileyo kunye nomsantsa wokuqina. I-coal asphalt ayilunganga kakuhle kwi-plasticity, ayizinzanga kubushushu, iyaphuka ebusika, ithambile ehlotyeni, kwaye iyaguga ngokukhawuleza.

* I-Binder: Yenza i-electrode, i-anode paste kunye nezinye iimveliso zekhabhoni i-binder, i-asphalt eguquliweyo ngokubanzi. Ngokuqhelekileyo, i-asphalt eguquliweyo ilungiswa nge-asphalt yobushushu obuphakathi. E-China, inkqubo yokufudumeza i-kettle isetyenziswa ngokubanzi, kwaye igesi isetyenziswa njengepetroli ukufudumeza i-asphalt kwi-reactor. Ekugqibeleni, i-asphalt eguquliweyo eqinileyo ifunyanwa ngokuhlukana kunye ne-granulation.

* I-Asphalt coke: intsalela eqinileyo ye-asphalt yamalahle emva kokuba ijijeke kubushushu obuphezulu okanye i-coke ecoliweyo. I-Asphalt coke idla ngokusetyenziswa njengezinto eziluhlaza kwizixhobo ezikhethekileyo zekhabhoni, nto leyo ebaluleke kakhulu ekuveliseni izixhobo ze-semiconductor kunye ne-solar panel. Isetyenziswa kakhulu njengezinto ze-electrode zokucokisa i-aluminium, izinto ezikhabhoniweyo kwi-oven yombane kunye nezinto eziluhlaza kwimveliso yekhabhoni kwi-semiconductor.

* I-Needle coke: i-asphalt ethambileyo ecociweyo ngokulungiswa kwangaphambili kwezinto eziluhlaza, ukucolwa okulibazisekileyo, ukucolwa kobushushu obuphezulu iinkqubo ezintathu, ezisetyenziswa kakhulu ekuvelisweni kwee-electrode kunye neemveliso zekhabhoni ezikhethekileyo. Iimveliso ezenziwe ngezinto zayo eziluhlaza zibonakaliswa kukungaxhathisi okuphantsi, umlinganiselo wokwanda kobushushu ophantsi, ukumelana nobushushu okunamandla, amandla aphezulu oomatshini kunye nokumelana okuhle kwe-oxidation.

* I-Carbon fiber: i-fiber ekhethekileyo enomxholo we-carbon ongaphezulu kwe-92% ofunyenwe kwi-asphalt ngokucokisa, ukujikelezisa, uku-pre-oxidation, i-carbonization okanye i-graphitization.

* I-oyile felt, i-activated carbon, i-carbon black kunye nezinye iindlela zokusetyenziswa.
