Tembiricha yemhirizimba
Chigadzirwa Kugadzirwa Kugadzirira nzira
High-tembiricha yerara tar ndeye byproduct yakawanikwa kubva kumusoro-tembiricha yakaoma yakaoma yemarasha. Iyo yakasviba yakasviba mvura ine kunhuhwirira kwakakosha. Izvo zvinhu zvikuru zvinonyadzisa hydrocarbons uye organic compound zvine okisijeni, nitrogen, kana sulfu. Mushure mekupindirana kwekutanga, zvidimbu zvakaita seoiri yechiedza, phenol mafuta, mafuta emafuta, geza mafuta, uye mafuta anthracene anogona kuwanikwa nenzira inoenderera mberi; Zvidimbu zvakaita seanopenya mafuta, svutugadzike, mafuta epakati, mafuta anorema, uye mafuta anthracen anokwanisa kuwanikwa achishandisa nzira yepamoyo; Dambudziko rakasara riri asphalt. Kuwedzera kugadziriswa uye kunatsa kwezvikamu pamusoro apa kunogona kujekesa mabhenji, uye phenolene, kabhasi, mapuranga, anoputika, zvipuka, zvipuka, zvipuka, zvipuka, kana zvinonhuwira.
Nhanganyaya kune chimiro chemarasha tar
Coal tar pakamuri tembiricha ndeyemakamuri viscous mvura, uye density yeakakwirira-tembiricha yemahombekombe tar yakagadzirwa nekonzerese yakakwirira, kubva ku1.160 kusvika 1.220g / cm3. Inonyanya kuumbwa nePolycyclic inonhuwirira makomputa, ine zvisizvo zvemukati zveAlkyl anamatics, zvakanyanya kubhoira kwenzvimbo zvikamu, uye kugadzikana kwakanaka. Zvikamu zvacho zvine zvirimo zvakakwirira zveNaphthalene, nepo nhengo dzehama dzakanyatso kuderera, pamwe chete neye-methylnaphthalene
Iyo yekugadzirisa tekinoroji yechigadzirwa
Zvivakwa zveChikamu chimwe nechimwe cheTar chakasiyana, asi kune zvakawanda zvikamu nezvidimbu zvakafanana. Izvo zvinodikanwa kutanga kushandisa nzira dzinopesana kuti dzigure zvidimbu zvakasiyana siyana, zvakadai se phenol, naphthalene, anthracene, nezvimwewo
Iyo inobvisa imwe-chikamu chezvigadzirwa zvakamanikidzwa mune inoenderana zvidimbu uye zvimwe zvakapatsanurwa uchishandisa nzira dzemuviri uye nemakemikari.
Chidimbu chisati chasvika 170 ℃ chisina kujeka mafuta; Chidimbu chiri muna 170-210 ℃ chinonyanya kunaka mafuta; Chidimbu chikuru pa 210 ~ 230 ℃ is naphthaerene mafuta; Distillate muna 230-00 ℃ inonyanya kushambidza mafuta; Chidimbu chiri na 280-360 ℃ chinyonyanya kunakirwa mafuta; Chidimbu chiri na 280-360 ℃ Ishracene Oiri; Iyo yekutanga yekubika nzvimbo yeanthracene oiri chidimbu ndeye 310 ℃, uye iri 400 ℃ Kana ichivhara makumi mashanu muzana
Chinangwa Chibereko
Coal tar chimwe chezvinhu zvakakosha muindasitiri inokweretesa, accounting kweanenge 3% kusvika 4% yeiyo yemarasha akaiswa. Kuumbwa kwayo kwakanyanyisa kuoma, uye kazhinji, kwakaumbwa nemarasha
Iyo tar indasitiri inoenderana nekuparadzanisa, kucheneswa, uye kushandisa. Zvidimbu zvakasiyana zve tar zvinogona kuenderera mberi nekuparadzanisa zvakasiyana-siyana zvigadzirwa. Parizvino, zvigadzirwa zvikuru zvinobviswa zvinosanganisira:
. Inoshandiswa pendi nemushonga.
(2) Phenols uye homolologs yavo inoshandiswa kugadzira machira ekugadzira, engineering plastices, mishonga yekuuraya zvipuka, mishonga yemishonga, mafuta, * * * * etc.
.
. Nekuda kwekubereka kwayo kwakakwirira, iyo ichiri kuda kuenderera mberi nekushandisa.
.
. Inoshandiswa kugadzira matenga edenga, unyoro-humbowo matanda, kuvaka kwemugwagwa, uye kugadzirwa
Asphalt coke uye magetsi echira electrodes, nezvimwe
