Asphalt lokushisa eliphakeme
Isingeniso Somkhiqizo
I-High-Light-Lite Cool Tar iyingxube eyinkimbinkimbi yombala onsundu omnyama, okhishwe kusuka ku-coal tar ngokusebenzisa uchungechunge lokuphendula kwamakhemikhali emazingeni okushisa aphezulu. Lokhu okuqukethwe kunezinto ezihlukile ngokomzimba nakokhemikhali, okwenza zibubonise ukusebenza okuhle kwezicelo eziningi zezimboni nezemvelo.
Izinkomba zokusebenza ngokomzimba ze-High-Light Coal Tar Pitch zifaka i-viscosity, density, i-flash point, njll. Inkomba ebalulekile yokulinganisa ukugeleza komoya wamalahle wokushisa wamalahle, ongalinganiswa yi-portary velicometer. Lapho kukhuphuka ngobuningi be-high-izinga lokushisa lamalahle lwamalahle, kulapho kukhulu khona isisindo salo, kanye okuphambene nalokho. I-Flash Point isho izinga lokushisa eliphansi kakhulu lapho i-asphalt yamakhola yamalahle ephezulu adonswa khona.
I-High-Light-Light Coal Tar Pitch inama-adhesion amahle, ubulukhuni, nokuqina, futhi ingamelana nokushisa okuphezulu, ingcindezi ephezulu kanye ne-oxidation. Ukunamathela kwayo okuhle kwenza ukuthi isetshenziswe kabanzi emasimini anjengokulwa nokugqwala, ukunamanzi okuvumayo, nokwakha.
I-High Temperature Coal Tar Pitch inokuqina okuhle futhi kungagcina ukusebenza kwesikhathi eside kumazinga okushisa aphezulu. Ingasetshenziswa emasimini anjengokwakhiwa komgwaqo, ukuqina kokulwa nokugqwala kanye nokuvimbela amanzi, kanye nemboni yezokwakha. Ekwakhiweni komgwaqo, kusetshenziswa i-asphalt yamalahle ephezulu yamalahle esetshenziswa njengesengezo kukhonkolo we-Assalt Road ukuze kuthuthukiswe ukumelana nokugqokwa nokuphikiswa kwamanzi komgwaqo. Emkhakheni wokulwa nokugqwala kanye nokufaka ngaphansi kwamanzi, kungasetshenziselwa ukukhiqiza izimbobo zokulwa nokugqwala kanye nolwelwesi olungangeni manzi, ukuzuza ngokulwa nokulwa nokulwa nokuphikisana nemiphumela yokulwa nokuvimbela amanzi. I-High Temperature Coal taal asphalt isetshenziswa njenge-binder kanye ne-sealant embonini yezokwakha, engathuthukisa ukufakwa kanye nokusebenza okuzwakalayo kwezakhiwo.
I-High Temperature Coal Tar Pitch inezakhiwo ezihlukile ngokomzimba nangamakhemikhali, futhi ukusebenza kwazo kungathuthukiswa ngokuguqulwa ukuze kuhlangatshezwane nezidingo zezimo ezihlukile zohlelo lokusebenza. Ucwaningo nokusetshenziswa kwe-high-izinga lokushisa lamalahle lwamalahle kuhlala kwenza iziqubu, zibeka isisekelo sentuthuko esimeme imboni ye-Coal Tar Pitch.
I-Modified Coal Tar Pitch idlala indima ebalulekile ku-electrolysis ye-aluminium ezitshalweni ze-aluminium. Ngokuqondile, indima yayo ibonakala ikakhulu kulezi zinto ezilandelayo:
- Njenge-Binder: I-Modified Coal Tar Pitch iyi-Binder eyinhloko esetshenziswa ekukhiqizweni kwamabhlokhi we-anode abhakwe ngaphambili we-electroly aluminium. Amabhulokhi we-anode abhakwe ngaphambili angamabhulokhi e-carbon enziwe ngama-aggregates anjenge-petroleum coke kanye ne-asphalt coke, kanye nama-asphalt tatch njengezixhumanisi zama-electrolys cell. I-Coal Tar Pitch ingahlanganisa ngokuqinile ama-bond ndawonye, yakha izinto ze-anode ngamandla athile nokuvuselelwa, ngaleyo ndlela ngenze ngcono ukusebenza kwamaseli we-electrolytic kanye nokukhiqizwa kwe-aluminium.
- Vikela ukwakheka kwe-aluminium oxide: Ngesikhathi senqubo ye-electrolytic aluminium, i-aluminium ion ifakwa kalula e-aluminium oxide, engagcini nje ngokuthinta i-oxidation ye-aluminium kodwa futhi iholela ekungcoleni kwamandla. Ezinye izakhi eziku-Modified Coal tal pitch zingavimba ukwakheka kwe-aluminium oxide, ngaleyo ndlela kuthuthukise ikhwalithi kanye nesivuno se-aluminium.
Ukuthuthuka okuthuthukile: I-Modified Coal Tar Pitch ingathuthukisa ngokuphumelelayo nokuvuselelwa kwe-electrolyte, okuvumela ukuthi kube lula ukugeleza kahle, ngaleyo ndlela kuthuthukise ukusebenza kahle kokukhiqiza kwe-electrolytic aluminium.
- Njengokubekwa uphawu kokubekwa uphawu kanye ne-adsorption: phezulu nangaphansi kweseli ye-electrolytic, i-modifid taal tal pitch ingakha ukufakwa kwe-electrolyte nokungena ku-electrolytic cell, ukuqinisekisa ukusebenza kwezinsimbi kweseli le-electrolytic. Ngasikhathi sinye, kungaba ne-adsorb futhi ususe amagesi alimazayo kanye nokungcola kweseli ye-electrolytic, ngcono ikhwalithi ye-electrolyte kanye nobumsulwa bokukhiqizwa kwe-aluminium.
- Ngamafuphi, i-Modified Coal Tar Pitch idlala izindima eziningi nge-electrolysis ye-aluminium ezitshalweni ze-aluminium, kufaka phakathi ukubopha ama-alumina, ukuthuthukisa ukuthuthuka, ukubekwa uphawu, kanye ne-adsorption. Kubaluleke kakhulu ekuthuthukiseni ukusebenza kahle kokukhiqiza kwe-aluminium electrolysis, ukunciphisa izindleko, nokuqinisekisa ikhwalithi ye-aluminium.
Ubuchwepheshe bokukhiqiza
Indlela ye-Thermal Polymerization yokuguqulwa kwe-asphalt ivame ukwamukela inqubo eqhubekayo ye-kettle, futhi i-kettle yokusabela ingasebenza engcindezi emkhathini noma ingezwe. Ngesikhathi sokusebenza kwengcindezelo yezulu, i-asphalt eshisayo igeleza eKettele esuka esigabeni sesibili se-Evaporator yesibili ye-Coal tar distillation unit futhi ifudunyezwa ku-kettle ukwengeza i-asphalt eguquliwe. I-asphalt eguquliwe igelezela ethangini eliphakathi le-asphalt eliguquliwe ngokwalo futhi bese lithunyelwa ethangini eliphakeme le-asphalt ngokusebenzisa elipholile. Ngemuva kokupholisa kwemvelo ku-150-180 ℃, kubekwa emshinini wokupholisa wokupholisa asphalt ukukhiqiza imikhiqizo ye-columnar. Amafutha negesi akhishwe esiqongweni sefomu le-reactor flash flash oil kanye negesi engabonakali ephelelwe yi-condenser. Lapho usebenzisa umsebenzi wokuhlola, i-asphalt eshisayo idlula ethangini eliphakathi nendawo le-asphalt eliphakathi nendawo futhi ligcwele i-kettle yokuphendula. Ingcindezi ngaphakathi kwe-kettle igcinwa ngo-0.5 ~ 1.2MPA, kanti okunye kuyafana nenqubo eqhubekayo yengcindezi yomoya we-kettle. Uma kuqhathaniswa ne-armoskeric cressresteres armerization, izinzuzo ze-thermal polymerization zithuthukiswe ikakhulukazi ukuwohloka okushisayo, okubangelwa ekukhuphukeni okuphezulu kokuqukethwe kwezakhi zama-asphalt aphansi, kanye nokwanda okukhulu kwenani le-asphalt elilungisiwe. Lapho izinga lokushisa elithambisa lidinga ukwandiswa, ipompo ye-vacuum ingaqalwa ukulungisa iziqu ze-vacuum phezulu kwe-flash distillation tower, ivele ivele ngokuqukethwe kawoyela kwi-asphalt elungisiwe; Lapho kunesidingo sokunciphisa izinga lokushisa elithambisa, uwoyela we-flash ungafafazwa embhoshongweni we-flash. Isivuno se-asphalt elungisiwe sisebenzisa izinga lokushisa eliphakathi nendawo njengento eluhlaza ~ 96% ~ 96%, kanye nesivuno se-asphalt elungisiwe sisebenzisa i-COAL TAR njenge-58% ~ 60%.
Okuhlosiwe
I-Moviefied asphalt isetshenziswa embonini ye-Aluminium Electrolysis ukukhiqiza amabhlokhi we-anode abhakiwe, ukukhiqiza izinduku ze-electrode ephezulu, ama-graphite ama-clan, futhi nawo angasetshenziswa njengama-electrode, futhi angasetshenziswa njengama-electrode ama-linder, izibopho zezinto ezibonakalayo, njll.
