Isingeniso Somkhiqizo
I-Coal Tar Pitch, eyaziwa nangokuthi Coal Tar Pitch, uhlobo lokuphikisana nokudla okunensalela okushiywe ngemuva kokugcona nokucutshungulwa kwe-coal tal ukususa izingxenyana eziwuketshezi. Ngokuvamile kungukulingwa okubonakalayo, okuqinile noma okuqinile, okumnyama ngombala kanye nokucwebezela, ngokuqukethwe kwekhabhoni okungama-92% ~ 94% kanye nokuqukethwe kwe-hydrogen okungama-4% ~ 5%.
Izici eziphambili ze-Coal Tar Pitch zingama-polycyclic kanye nama-polycyclic aphuku le-hydrocarbons kanye nezinto zazo zokuphuma kwazo. Ukwakheka okucacisiwe okuyinkimbinkimbi kakhulu, futhi umehluko ohlotsheni amalahle eluhlaza kanye namasu wokucubungula nawo ungaholela ekuhlukeni kwezakhi. Indlela yamanje ikakhulukazi ihlukanisa ngokususelwa ekushiseni okuthambile okukhombisa.
I-Coal Tar Pitch inezimpawu ezilandelayo:
- Ukuqina kokushisa okuphansi kanye nokuthambisa okulula lapho kufudunyezwa.
- Ukunamathela okuhle ngezinhlanganisela zamaminerali.
- Ukuqina kwesimo sezulu kumpofu, futhi ngaphansi kwemiphumela ephelele yokushisa, ukukhanya kwelanga, umoya-mpilo, njll.
- Ipulasitiki empofu, ithambekele ekuqhekekeni ngenxa yoguquko ngaphansi kwengcindezi.
- Kuqukethe i-phenol, anthracene, i-naphthalene Amafutha, nezinye izinto, ngakho-ke inezakhiwo ezinhle zokulwa nokugqwala.
Ngokuya ngamaphuzu ahlukile wokuthambisa, i-coal tart pitch ingahlukaniswa izigaba ezintathu: iphimbo lokushisa eliphansi, indawo yokushisa ephakathi nendawo, kanye ne-pitch ephezulu, iBanga lesi-2 nebanga lesi-2. Ukusetshenziswa kwalo okuyinhloko kufaka:
- Kusetshenziswe njengophethiloli
- Ukukhiqizwa Kwe-Carbon Electrodes: Iziqu zabo ze-Carbon Grashtization ziphakeme kakhulu, futhi zingasetshenziswa njengezinto zokwakha i-electrode zokukhiqiza, kanye nama-ejenti nama-wetting anchents kanye nama-linders.
- Ukukhiqizwa ngopende: Ngemuva kokucutshungulwa, kungasetshenziswa njengenhlanganisela engangeni manzi yezakhiwo namapayipi, njenge-epoxy yamalahle amalahle e-coating.
- Isetshenziselwa ukwakhiwa komgwaqo nezinto zokwakha: ngokuvamile kuxutshwe ne-petroleum asphalt, ukusebenza kwe-asphalt exubile kungcono kunokuzisebenzisa ngokwehlukana, kepha i-coal tar inezinto eziyingozi kakhulu futhi idinga ukuphathwa ngokungafanele ngaphambi kokusebenzisa.
- Khiqiza imikhiqizo engezwe ngenani eliphakeme njenge-witle coke, i-carbon ecushiwe ecushiwe, i-carbon fiber, njll.
Lapho usebenzisa i-coal tal pitch, ukunakwa kufanele kukhokhwe ubuthi bayo ukugwema ukulimaza impilo yabantu, futhi ukuvikelwa kwemvelo kufanele futhi kubhekwe ukunciphisa ukungcoliswa kwemvelo ngesikhathi sokukhiqiza nokusetshenziswa kwayo.
